Which Cell Phones & Networks for SSH?

Cliff posted more than 9 years ago | from the GPRS-and-port-22 dept.

Communications 81

muffinresearch asks: "I've been thinking about picking up a new PDA/Smartphone in the seasonal sales, I am finding a lack of more technical information with regards to being able to use SSH software via GPRS. Now as far as I can see, the Treo 600, and the Sony-Ericsson P900/P910i can all use third-party SSH clients.However what is lacking here in the UK is info on which networks allow access on port 22, and whether this access requires a pay-monthly account or can you do it on a Pay-as-you-go account? I'm reckoning some of you will have useful info on what is working for you as far as phones and networks that do SSH, and your experiences in practice. Happy New Year to all!"

Idokorro (3, Informative)

innosent (618233) | more than 9 years ago | (#11230923)

Idokorro offers SSH clients for most J2ME phones, including the various blackberry devices, and also offers one for the Nokia phones with the flip-over keyboard (can't remember the model number). Try Idokorro [idokorro.com]

Geoffreyerffoeg (729040) | more than 9 years ago | (#11231014)

1) Idokorro is definitely not Free, and quite expensive too. BlackBerry SSH starting at $195!? He's probably buying his phone for less than that. (Their Mobile Admin software [$1 995] looks pretty interesting, though: Active Directory, Novell administration, SSH, etc. from a BlackBerry.)

2) He can find clients; his question asks which services have Port 22 access, or which have people used successfully for SSH.

cat5 (166434) | more than 9 years ago | (#11231427)

It's available for the Nokia 6800 (6810, 6820, 6820i) series. I have a 6800 flip for over a year ;) and I must say, SSH is SLOW!

SSH is almost impossible to use on this phone, as the processor is not fast.. but wait.. the 9300/9500 communicators (same price range) are much faster, as I have/am beta testing a 9300 now.. and WOW.. everything is fast!!

Re:Series 60 (2, Informative)

Nestafo (777210) | more than 9 years ago | (#11261891)

I am very satisfied with a Series 60 version of Symbian Putty [sourceforge.net] . It works great with my Nokia 6600 by using GPRS services of major Finnish cellular operators.

I can easily use Pine and Irssi [irssi.org] in my Unix screen. Actually I've found that using the phone's own mail client is much clumsier.

Small screen of 6600 is surprisingly no problem. The only limitation is slow text input. T9 helps you to input fast normal text, but finding some special characters may take a while. The developers of Symbian Putty have been really helpful and actually added some special key shortcuts after my request.

Ping Times (4, Insightful)

BrookHarty (9119) | more than 9 years ago | (#11231035)

My pingtime is 600ms over GPRS and 200ms over UMTS. I've seen it bounce upto 2000ms with boats on the water in NY and not loose a ping.

Myself, I'm using my UMTS Motorola A845 phone as a usb modem, I can still take calls while I vpn and ssh out. Gives me about 3 hours combo surf/talk time before I need to charge, so I leave it plugged in at my desk while I do both.

Nice thing, no matter how much filtering IT does, I just route out over my phone connection... BTW, jerks are filtering some slashdot urls.

Also, While those GPRS phones are only Voice or Data at once, UMTS lets me do both at the same time, I dont have to quit my data session. I havnt tried the bluetooth, but been wanting to see how my pocketpc can ssh out while im on the phone.

UMTS is great, glad that its starting to go nation wide. DO and VO products just are not what you want.

Danger Hiptop (2, Interesting)

jeif1k (809151) | more than 9 years ago | (#11231085)

Get a Danger Hiptop from T-Mobile. You turn it on and it just works. It supports web browsing, E-mail with push, AIM, SMS, a regular cell phone, a transparently web-synchronized organizer, some games, a VGA camera, Yahoo Messenger, and SSH (plus several more applications that I haven't tried). You also get an E-mail address and web-based access to your data. Also, the keyboard is the most usable among all the devices I have tried.

The device is $200 and you pay $20/month for unlimited data services. You have to add a voice plan to that; the cheapest is another $10/month, making the device $30/month (1 year commitment).

Re:Danger Hiptop (1)

rusty0101 (565565) | more than 9 years ago | (#11231189)

Not sure if T-Mobile is a viable solution for him in the UK. If so, great, otherwise see if there is a service that provides something similar for data services.

Re:Danger Hiptop (2, Interesting)

daviddennis (10926) | more than 9 years ago | (#11231293)

They do charge $10 for the SSH client, which I think is pretty reasonable considering that not many customers on a percentage basis are going to want it.

I have the T-Mobile Sidekick and I can say that it's a great feeling being able to SSH on my cellphone without worrying about the enormous monthly fees associated with other carriers.

But there are a few downsides. The main one is that T-Mobile service is pretty bad in many places, including Los Angeles, where I live. When it works, it's great. When it doesn't work, you can find yourself staring at a broken antenna icon for rather longer than I would hope.

Verizon has somewhat better service, from what I understand, but all cellphones seem to have trouble at one time or another. I will say that T-Mobile customer service is pretty good, and you can get the SideKick II and start service for very little out of pocket money. (Watch out for those cancellation penalties, though!)

The SSH client does work and it has saved my bacon a few times already. So I recommend it with reservations about service. If you can, check with fellow Sidekick users in your area before buying.

nyquil (23124) | more than 9 years ago | (#11240118)

Well, in all fairness, the source for the ssh client is distributed with the SDK; a free download. Anyone techy enough to want to use the ssh client can just sign up for the sdk and install it that way. There's tons of applications you can install from skdr.net, all written by users.

Re:Danger Hiptop (2, Interesting)

gabe (6734) | more than 9 years ago | (#11232105)

Danger's platform is limited for developers, so you'll be able to find better apps for other devices that use J2ME, Palm, WinCE, etc. Having said that, the Sidekick/Hiptop II has a very nice web browser, AIM client, etc. But it's quite clumsy as a phone (have to open it up to dial numbers - or selected them from a list on the phone using an awkward scroll wheel).

Re:Danger Hiptop (1)

jeif1k (809151) | more than 9 years ago | (#11232134)

Danger's platform is limited for developers, so you'll be able to find better apps for other devices that use J2ME, Palm, WinCE, etc.

I think what matters is not the total number of applications, but that it gets the job done. And when it comes to mobile Internet access, I think the Hiptop still beats any of the Palm, Windows, Symbian, or Blackberry-based offerings.

But it's quite clumsy as a phone (have to open it up to dial numbers - or selected them from a list on the phone using an awkward scroll wheel).

True, but that's not so different from a flipphone. Also, it has a speakerphone and comes with a headset, which I tend to use when I make a number of phonecalls anyway.

Re:Danger Hiptop (1)

faster (21765) | more than 9 years ago | (#11232141)

awkward scroll

I was with you up to this point.

I like the scroll wheel. It's not perfect, but the UI on the Hiptop is far superior to the waggle-wheel on the blackberry and the pinhead-keys on the Treo (though there are TONS more apps for the Treo).

Other comments about Hiptops and T-Mobile are right on. Spotty service, mostly-good (or better) customer service), cheap phone if you buy on Amazon with voice service. The phone part is a good phone, though it is pretty much impossible to use while driving. I consider that a good thing, but not everyone can ignore a ringing phone even when digging for it and looking for the right button to push can endanger your life.

Re:Danger Hiptop (1)

stickyc (38756) | more than 9 years ago | (#11260029)

I'll second the vote for the Sidekick II. Despite the snoop-dog/Paris Hilton marketing angle, it's actually a fairly good power tool for the road-warrior.
The SSH client supports multiple simultaneous sessions, SSH2, Telnet, and "raw" modes, up to 999 line scrollback, saving login information (with or without passwords), multiple font styles, vt100, ANSI, xterm, and 'linux' terminal emulation (but alas, not alternate ports). T-Mobile does not block port 22 and I've had great success logging in remotely to my home systems.
It also supports IMAPS, although it behaves like a POP account in that it only retrieves emails, there's no folder support and deleting mails from the local device does not delete them from the server. In the end, I prefer this as my inbox often has hundreds of messages and I really only care about the new ones.
If you're willing to forgo T-Mobile's lackluster phone support, you can get a development key that allows you to upload applications outside the normal channels. There's a fairly active development community creating 3rd party apps. Some good ones include a full-featured RSS reader, e-book reader, unified IM client (AIM, Yahoo!, and Jabber).

Of course, since you're in the UK, I dont think this is of much use to you since as far as I know, the Sidekick II is a US only product right now. However, for US folks that are interested, Amazon's got it for $-50 with rebates (that means you get $50 back, about half the first phone bill including setup fees).

putty & a 6600

was great to be sat on a campsite in cornwall @ 10pm, getting a text from work and me ssh'ing into the server and sorting it out without moving

O2 gprs

the bluetooth keyboard doesn't help that much, you have to enter text into putty one line at a time through a dialog box

options .. send text .. [dialog] ... ok

not quiet like using a keyboard at a prompt and certainly not very curses friendly

with the added benefit that agile messenger works (IM client for icq, yahoo, msn & aol)

my friend has a sonyericsson p900 and can VNC into stuff to do work on T-Mobile but he can''t get agile to work at all, despite talking to support "well, it *should* work" is the best they could tell him !

also the 6600 is crippled for bluetooth networking so all traffic is via the GPRS, I've tried gnubox to no avail. (though I've not exhausted the permutations of dongles & base stations & sorting out interference with wifi etc.)

there's even python for series 60 now

I've avoided MSWindows based phones myself as I'm predjudiced against anything that says "synchronizes easily with Outlook" on the box :)

I've had poor luck with Cingular for GPRS. Including the on-phone GPRS service. I switched over from AT&T and have been unhappy. Hopefully ATTWS will bring some clue to the data side of Cingular. They're also not bluetooth or mac friendly.

Re:not cingular (1)

Yaztromo (655250) | more than 9 years ago | (#11237744)

They're also not bluetooth or mac friendly.

Other than for documentation/support helping you to initially set these things up, both are functions of your phone rather than your cell provider.

I just got a Sony Ericsson T610, running on the Fido network hre in Canada. They aren't Mac friendly from what I can see (they provide no mention of it anywhere in their documentation or online), and provide very little Bluetooth information, but I was still able to get full connectivity between my T610 and my PowerBook G4 quickly and easily just by using Apple's Bluetooth setup wizard.

If you're having problems, chances are it's either user error or due to problems with the phone you've chosen (some early Bluetooth cells don't properly implement the spec, for example), and should have nothing to do with your provider.

Re:not cingular (1)

jaredmauch (633928) | more than 9 years ago | (#11238121)

Well, somewhat true, but the issue becomes that when I am getting dropped GPRS connections after under 5 mins of use, and I call them up and they say "screw you, you're trying to use your phone like a modem, we don't support that either" it's more of a function of the provider than the phone/setup i have going..

Try this. Go into System Preferences -> Network -> Bluetooth (or whatever connection type you're using) -> PPP -> PPP Options, and disable "Send PPP Echo Packets".

Orange pay as you go (2, Informative)

megan_of_wutai (649071) | more than 9 years ago | (#11231784)

The Orange pay as you go GPRS "extra" seems to allow all ports.

I've used SSH and IRC and AIM and others over it with no problem (apart from the hideous latency mentioned by others). This is with a Zaurus SL-5500 and a T68. The guy at the support desk who I asked before I got it said that I wouldn't be able to unless I was contract, he lied :-P.

One thing to watch out for if you use linux is that the networks (at least orange and t-mobile) ignore LCP echo requests, which makes your connection time out after 2.1 minutes unless you tell the pppd to forget about those.

I've had friends who tried O2 pay as you go GPRS and found it to be strictly limited to a port 80 proxy server.

Verizon's CDMA2000 1x EV-DO service is available in certain areas right now (14 cities), and it's going nationwide next year.

It's ~400kbps with decent (~200ms) latency. When you aren't in a EV-DO area, it drops back to the ~80kbps 1xRTT standard, still with decent (~500ms) latency.

$80 a month for unlimited data. You can get a discount if you are using it with a PDA and not a PC.

Re:Verizon BroadbandAccess (1)

macdaddy (38372) | more than 9 years ago | (#11232260)

I have a Verizon phone (LG VX7000) and have been fairly impressed with it. I really liked the usability of my Nokia 6120i but its range and battery life sucked. Plus that carrier wasn't in the Wichita, KS area. I am however more than a little disappointed with the speed of the 'Net access and how it's all but unusable on my phone. The transfer rate is neglible and it takes an act of Congress to type in URLs on this phone (not to mention log in with a numeric userid). I should probably just drop the 'Net access option from my phone since I rarely use it (or can use it). I text message often (usually to Google SMS or receive stock alerts from Scottrade). The next time I upgrade my phone I hope to buy a Treo or BlackBerry of some sort. To do that I'll have to be at a point in my life where I'm carrying my engineering bag, briefcase, or some other container which can protect my extrememly expensive phone from damage. However I know I won't be able to carry it everywhere like I carry my LG or my old Nokia. I wish Verizon would allow me to attach another phone to my number for, oh say, $10/month or so. That would be worth it to me if I owned one of those nice PDA-phones. I won't buy one of those phones though until the speed is decent. I think one of those PDA-phones will solve my usability problems. The speed matter still needs to be resolved though. Do you have the new highspeed broadband access? Like it? What phone are you using?

Experience of ssh over gprs worldwide (5, Interesting)

sl956 (200477) | more than 9 years ago | (#11231920)

I am a heavy user of ssh over gprs (or gsm where gprs is not available):
I usually don't need/want a laptop when I am traveling so I initially went the PDA+cellphone way.
I have used my old Zaurus SL-5000D with a bluetooth CF-card and a triband SonyEricsson cellphone (T68i, then T630) to ssh into my european servers from Europe (UK, Italy, NL), the US (NYC, LA), Asia (HK, Cambodia, Thailand) and even from Japan, using a rented blutooth-enabled cellphone.
It has always worked flawlessly. I never had any problem with blocked 22 port or anything like that in any of these countries.
I considered the Treo 600 very seriously, but I will stick to my current PDA+cellphone solution. In Japan the Treo would be as useless as my Sony-Ericsson. But it is a lot easier to rent a simple bluetooth-enabled cellphone and use my usual PDA than it would be to rent an integrated local smartphone with an ssh client.

For the networks questions, there are more problems : if the cost is not important (company paid for instance), just use the roaming partners of your cellphone company : the big european players (Vodafone, Orange, T-mobile) usually try to have at least one partner allowing data in every country (be it over gprs or gsm). But it is expensive, and the costs are very difficult to predict. So if you want to optimize, you have to buy pay-as-you-go plans in every country, being careful to choose plans allowing data. You usually have to pay a premium for data but it is a lot cheaper than simply roaming.
The biggest problem then becomes to choose the right simcard from you (huge) collection depending on the place where you are. It can sometimes be tricky like : So I am in Cambodia near the Thailand border and I don't have any Cambodian pay-as-you-go plan. Choices are using my 12Call simcard because i am not far from Thailand and I can see their network from here, or using my SmarTone simcard, roaming through a local network to HongKong, or simply use the local roaming partner of my european network. Which one would be the cheapest??? The answer, found by trying, was using my HongKong pay-as-you-go plan (SmarTone). Please don't ask me why. :-)

Just my two euro-cents.

You are aware that you could just have bought (or rented) a local SIM card and use it with your foreign phone? That's usually very easy to do (Thai phone companies used to block foreign phones from using their SIM's, but they changed their mind about that years ago).

I spend a year travelling in 2001/2002 and I had good results using a Nokia 9210 for mail and SSH world wide. The GPRS thing was just starting then so I used normal dialup with GRIC as a roeming dial in provider so I could dial in to the 'net locally.

ATT/Cingular & Nokia 6820 (3, Informative)

gabe (6734) | more than 9 years ago | (#11232122)

I use a Nokia 6820 with ATT Wireless/Cingular. It has a fold out keyboard which is quite nice. ATT/Cingular both have unlimited data plans for around $20/mo. ATT Wireless charges extra for data usage by a device hooked up to the phone (Bluetooth, data cable -> laptop) but Cingular does not.

When I need to use SSH and don't have my laptop, I use MIDP SSH [xk72.com] , which is free and "good enough." Ideally I'd wish for a bigger screen only. (From your cellphone: http://www.xk72.com/wap [xk72.com] )

I've found mobiledia.com's forums [mobiledia.com] to be quite helpful also.

no problems with treo 600 and Cingular (1)

neilsly (106751) | more than 9 years ago | (#11232358)

no problems to report with my Treo600 and Cingular - lag is pretty high though, not something I'd want to use every day but it's sufficent to reboot a server or kill a proc if needed.

SprintPCS + Treo600 + pssh (1)

_aa_ (63092) | more than 9 years ago | (#11232472)

I use SprintPCS [sprintpcs.com] , the Palmone [palmone.com] treo600 [palmone.com] , and pssh [sealiesoftware.com] . SprintPCS's network is CDMA [wikipedia.org] so if you're not in the continental United States, and not in or near a metropolitian area, forget about it. For the rest of you I can tell you that it works splendidly, though latent. It'd be difficult to perform any complex task, though not impossible. On the treo the font-size will be tiny. One should consider the treo650 [palmone.com] with it's high resolution screen as an alternative.

I should also mention PalmVNC [palmvnc2.free.fr] . The bandwidth limitations of the sprintpcs network, and the resolution limitations of the treo600 render this application to little more than a novelty. Though again, in a pinch, it's a usefull app to keep around.

Perhaps you already have a phone that runs java midlets? If so you could try SSH & Telnet Floyd [inf.upol.cz] or MIDPSSH [xk72.com] .

O2 OK in UK (1)

babycakes (564259) | more than 8 years ago | (#11232844)

I've had success using PuTTY for Symbian OS [sourceforge.net] on my Nokia 6600 on O2 - am on a contract (one of the "online" tariffs) with them, and after installation on my phone, it worked straight away with no need to call them up. Haven't had the chance to try with pay-as-you-go however, but contract is fine.

o2, laptop, Bluetooth & Corkscrew (1)

dan_polt (692266) | more than 8 years ago | (#11233165)

I use o2s basic online deal with my laptop. Its evil bad and wrong but I then use Corkscrew [agroman.net] to tunnel through their proxy. Its not great (times out after 10mins [1]) but the deal I have has lots of free access, and it keeps me connected when i'm away for a real connection.

I've also used proxytunnel [sourceforge.net] not sure which I prefer.

Downsides (2, Informative)

PapaZit (33585) | more than 8 years ago | (#11233233)

My setup: T-Mobile w/ "Unlimited Internet", Nokia 3660, Palm Zire 72 (bluetooth to phone).

I've used both the Symbian PuTTY port and various palm SSH apps. They work, but there are some significant problems:

-Latency is huge (I've seen over 2000ms). You'd better type it correctly the first time.

-Input is difficult, particularly when you need non-alphanumberic characters (pipe, braces, escape, control characters). You'll want to figure this out before you need it.

-For the above reasons, you may want to think about something with a small keyboard. Still, remember that the little keyboard is still going to be short on keys. Figure out how to enter the "missing" characters.

-You don't get a "real" IP address. It's a 10.x.x.x address going through a NAT. Be sure that any firewalls or admin tools can cope with that.

-The battery drain for this is pretty significant. I get about two hours total use. That's fine for quick fixes, but you won't want to stay logged in to watch an hours-long database rebuild.

-Given the odd screen size and intermittent connectivity, screen [gnu.org] will become your best friend.

Sidekick solves most of that (1)

Beltway Prophet (453247) | more than 8 years ago | (#11233809)

I have to say, the Sidekick really comes through for SSH. There are a few keyboard shortcuts you have to learn (and they're pretty much mnemonic once you figure out that Menu==Ctrl, but they're shown in a pop-up dialog if you forget) but braces, brackets, angles, and most other punctuation are all printed on the keyboard.

Sadly, they hurt the keyboard on the Sidekick II by recessing it so you have to hook your thumbs around the case, and by replacing the soft-topped keys with chiclets. The Sidekick 1 (both mono & color) has the best keyboard of any PDA I've ever used.

Battery life is phenomenal; I can stay online all day in AIM and SSH and still have a bar or two left over. Latency is the only real problem, and there is a line-entry mode if you want to type a long/complex command. I also like the way you can maintain several sessions concurrently.

Dial 611 on the phone to talk to T-Mobile customer service and ask to change your Unlimited Internet service option to the VPN Unlimited Internet option. If the customer service representative you speak to doesn't know what you're talking about, call back until you find one that does. The VPN option gives you a real IP address.

GNU screen [gnu.org] is always your friend. Next to emacs, it's the most ginomously useful piece of software ever written for anyone who logs into a shell, remotely or not.

O2 (0)

Anonymous Coward | more than 8 years ago | (#11233408)

A couple of months ago I was using my O2 (online tariff) phone to SSH into my computer at home.
You connect using the '915000' number, username=o2wap password=02wap. You may need to manually set the DNS servers, otherwise you can SSH into your machine as you would from any other internet connection. Lags alot (~900ms latency) but otherwise still usable at 9600bps. (I recommend using the -C option to ssh when connecting as this will compress the data.)

The sidekick (1)

NateKid (44775) | more than 8 years ago | (#11235253)

I've found that the The Sidekick [t-mobile.com] is just incredible. It has an ssh client, decent webbrowser (though it has trouble with tables/frames/scripting, etc.) and convenient keyboard, as well as decent phone features.

And I am speaking as an owner of the color sidekick - supposedly the newest iteration is significantly enhanced. The only downsides are that
1) the reception isn't 100% (though I hear the newest one is a lot better wrt this).
2) it breaks a lot (though they do have a generous exchange policy).

Anyway, if it's available in your area, I'd definitely consider it. There is no extra charge for any internet usage (about $60/month gives me the package I need) and the ssh app is probably less than $5 to buy. If it doesn't work for you, I hope somebody else benefits from my recommendation.

Re:The sidekick (1)

NateKid (44775) | more than 9 years ago | (#11237576)

The name is just "terminal client" and it lets you telnet and ssh. The charge for it is $9.99 on my phone, but I think I got it for free way back when.

Vodafone (1)

tengwar (600847) | more than 8 years ago | (#11235632)

Vodafone in the UK allows port 22 on contract GPRS - haven't tried prepay but I think it will be the same. The firewall rules will be associated with the APN (access point name - roughly equivalent to a modem bank for a circuit-switched service) and as far as I know prepay customers can use the same "internet" APN as can contract customers (user name "web", password "web". The only issue with that APN that I know of is that HTTP traffic is optimised for the low bandwidth, which can degrade image quality - not an issue for your application.

BTW, I only use SSH from a laptop with a GPRS PC card, so I don't know how well the handset-based applications work.

Re:Vodafone (1)

robjs (724390) | more than 9 years ago | (#11243000)

I own both a Vodafone Business contract (with a Nokia 6230) and one of the Vodafone 3G/GPRS cards. With the handset, linked via Bluetooth to a laptop, I've been able to access SSH/IRC/MSN etc. (Note that it's all behind NAT). However, with this approach, the latency on the session is way too high for it to be usable.

However, with the 3G card, in a Vodafone 3g enabled area (this is getting more and more widespread now, initially I only got 3G in London and Manchester, now it seems to be spreading, and I've got a 3G connection in Huddersfield, Luton, and Oxford) the latency is nice and low, and it feels like you're working on a 128k+ connection. I've used rdesktop (uh, Terminal Services sorry), telnet, SSH, MSN, IRC, HTTP, POP3, IMAP, IMAPS - basically, just about anything) and there's been no problem.

I had (it got half-inched recently) a 15" Powerbook, and using the datacard in OS X was nice and easy, however the features of the Mac software left a little to be desired compared to those of the PC software (there's no text messaging support, data usage tracking etc). The most annoying thing is that, with the new cards that don't use an antenna, there's interference on the speakers from the card, which gives that annoying clicking tone.

So, returning to the original question, yes, no problems with using SSH (or any other protocol) through Vodafone's network, however, I'd definitely recommend their datacards, rather than phones, purely because of the ease of use, and ease of input.

Re:Vodafone (2, Informative)

tengwar (600847) | more than 9 years ago | (#11243989)

the latency on the [GPRS] session is way too high for it to be usable.

There's an intrinsic issue with GPRS. GSM is a time-division system with eight slots - the phone encodes voice, then sends it out in a burst during it's slot, and reverses the process to receive. This puts about 1/4s delay in, which doesn't matter for voice unless you're on a conf call with one of the other parties in direct hearing range.

GPRS was a simple, cheap and technically conservative upgrade to GSM to send packet data in unused time slots. This introduces the latency: you have to wait for the slot, and if you have a large packet it will be fragmented into more than one slot. UMTS (3G) on the other hand was designed for data from the start, so no time division.

Another consideration if you are roaming is that your data will usually be tunnelled back to an GGSN (a router) in the home network which hosts the APN you are using. This can add some latency for general Internet use. There is some capability to tunnel to an APN in the visited network, but I don't know of any networks that actually do this as it would require more cooperation between the home and visited networks. More importantly, the APN is the point at which the home network can add "value added services", e.g. optimisation of HTML, so they usually see a justification for looping the user plane data back home, and would prefer to pay for the international bandwidth to do this.

Some useful information. (2, Interesting)

Yaztromo (655250) | more than 9 years ago | (#11236507)

I've recently hooked myself up with a similar set-up, and have recently been writing about it in my journal [slashdot.org] . I'll detail it a bit here.

Here's what I'm running:

How everything is connected:

  • The PowerBook is outfitted with WiFi (802.11g) and Bluetooth, using WiFi when at home/office, and GPRS through the T610 via Bluetooth when on the road.
  • The Tungsten C is outfitted with WiFi (802.11b) and InfraRed, using WiFi when at the home/office, and GPRS through the T610 via IR when on the road (technically I can get it online via WiFi if I use the PowerBook as a bridge in ad-hoc mode, but it is exceedingly rare that I'd ever need to have both the laptop and the T|C online at the same time when outside WiFi range).

So far, this is a set-up I'm quite pleased with. The only way it could be better were if the Tungsten C supported Bluetooth as well as 802.11b.

I can't recommend Bluetooth highly enough for this sort of connectivity either. So long as I'm within 10m of the phone, I can connect to it from the laptop. And Mac OS X's Bluetooth support is excellent -- I'm able to synchronize my contact list and calendar, transfer files back and forth, send and receive SMS messages from my desktop, dial phone numbers, and connect to the internet -- all without wires, or any set-up hassle.

SSH has been important for me, as one of my primary uses for this sort of connectivity will be CVS source repository access through SSH.

I've only had the phone for a week, but I'm quite pleased with it in general. I could have done without the camera portion I suppose (the resolution and quality is terrible), but might come in handy for something someday.

Overall, the set-up appears to be working well, and I'm as pleased as punch with it. Everything is nicely portable, and I have instant access everywhere I go. Set-up has been a snap, and everything works as expected. Now if only I could get cable modem speeds out of this set-up, I'd never work at a desk ever again :).

Xenna (37238) | more than 9 years ago | (#11237796)

I bet you wouldn't want to run SSH on your desktop without a keyboard. So why would you want to on your phone?

IMO these devices are perfect for remote access:
http://www.nokia.com/phones/9300 [nokia.com]
http://www.nokia.com/phones/9500 [nokia.com]

The 9500 (big with Wifi & camera) has just arrived in the stores and the 9300 (smallet, more elegant, but without the former) will arrive this month. I'm probable going to get myself and my GF a 9300 later this year.

I wouldn't know about networks and prepaid stuff or the UK situation. Currently I use a Clie TG50 PDA with a SE T630 phone and I have been able to use SSH anywhere with my GPRS account (keyboard scuks, tho...). Since GPRS is usually billed by the MB, SSH tends to be very cheap even when I use it abroad.

Re:PuTT on Series 60 (1)

db (3944) | more than 9 years ago | (#11269287)

Err whoa, sorry, something odd happened there. I use Putty on a Nokia 6600 though T-Mobile in the US, and it works without a hitch. I have their unlimited internet plan (which is like $14.99/mo or something). Its free for me because I've been with T-Mobile since they were AirTouch, and was grandfathered into their GPRS unlimited plan. I'd say its a good combo -- typing is a bit arduous, but what are you trying to do over a phone, anyways? Code? Not likely.

If you want a full keyboard, try something more suited like an SE P900/P910a, Moto A1000, or any of the Nokia Communicators.
