vservers (-1)

Anonymous Coward | more than 10 years ago | (#7542600)

I own a shared ISP, and I am looking for a way to do virtual private servers under Linux. (basically, instead of sharing one server, everyone runs their own under a chrooted secure environment) I have looked at linux-vserver, but I want a mature and stable solution. sphera [sphera.com] is an option, but it is proprietary and expensive.

DDumitru (692803) | more than 10 years ago | (#7542817)

Your definately want UML.

http://user-mode-linux.sourceforge.net [sourceforge.net]

UML has a number of differences when compared to chroot environments.

  • Resource usage is higher because less is shared.
  • Each virtual needs a real network, and usually a real public IP
  • Network configuration can become nightmareish as the number of virtuals grows unless you write some signifigant config scripts that run dynamically.
  • You really need a good understanding of networking and especially routing and how ARP works. The docs on the UML site are correct, but they only scratch the surface.
  • You still have to secure the virtual on the host system. This usually involves running UML as non-root inside of a chroot jail that is as sparsly populated as possible.
  • You will want the SKAS patch.
    • With the SKAS patch, you will need a /proc in your chroot jail. Look at mount --bind to just mount /proc/cpuinfo and /proc/mm

On the other hand, UML is good enough to fool even the hackers (I have had UMLs hacked and the hacker didn't realize they were in a virtual).

We run public webservers, and mailservers on UML. We are at the point where we just assume that you use one UML per application. The manageability of running single-application servers is just too good to pass up.

Re:vservers (0)

Anonymous Coward | more than 10 years ago | (#7542953)

Why would you consider someone hacking a virtual server to be a fool? It's as good as the real thing to a hacker in many cases. And by the way: a simple cat /proc/cpuinfo will do the trick of identifying user mode linux.

Re:vservers (4, Interesting)

DDumitru (692803) | more than 10 years ago | (#7543049)

In one sense, hacking a virtual is as good as hacking the real thing. On the other hand, hacking a virtual is quite dangerous on the part of the hacker.

UML virtuals have the ability to log a bunch of stuff "outside" the virtual. This can include keystroke logging on devices (including the pty's that ssh allocates). Plus you have a 100% sniffable network from the outside and the "owner" of the UML can "give" the virtual to the hacker at almost no cost and watch and learn.

If you are concerned about a hacker launching a DDOS using your virtual, this can happen, but you can also stop or mitigate it without tipping your hand against the hacker. You can firewall the virtual from the host side and silently block all (or most) of the attacking packets. You can even rate-limit the damage that they can do with 'tc'.

The amazing thing about getting a UML hacked is that most hackers don't even realize they are being watched. While /proc/cpuinfo and a bunch of device setups are unique to UML, most hackers have no clue and trudge on blindly. If you want to be more "stealthy" and setup a honeypot, the honeypot /proc and /dev filesystems change all the names to match a "normal" physical server. If your purpose is a "honeypot", you will probably need to only run a single UML with enough memory to seem realistic. Even then, if the hacker knows the internals of Linux, he can tell, altough it might require writing/loading a kernel module to see that the address space is not quite right.

You might want to look at FreeVSD ( http://sourceforge.net/projects/freevsd/ [sourceforge.net] ). It used to be a commerical package and many ISPs have used it over the years. It hasn't been updated in a few months though since the company went under in Jan. 2003.

It has all your virtual server stuff and even has a web interface to manage everything as well, like the creation of new virtual servers, etc.

I don't see why the Open Source community couldn't pick up on it and update it for the last releases of Linux distributions. Everyone keeps saying that they would pay to help develop an Open Source virtual server program, well here is your chance to do so with a working program.

If you are looking for a web hosting control panel then you also might want to look at Vishwakarma (http://kandalaya.org/vishwakarma.shtml [kandalaya.org] ). It is a nice package and has been around for awhile with a nice web interface and even has support for reseller, and user management options.

in the enterprise datacenter has to be Cisco Enterprise Printing System of CEPS for short. With CEPS Cisco has over 10K printers in thousands of sites around the world with only 2 print admin's!! CEPS is based around SAMBA and CUPS and allows windows, linux, and unix clients to print to printers in a way that is unmatched for redundancy in any other product commercial or otherwise. Remote print servers can take over controll of print queues quickly in the event of a print server failure and queues can be rerouted to a new print device should a physical printer fail all without client reconfiguration! Cisco was nice enough to give the system back to the world. They have a sourceforge [sourceforge.net] project available for anyone interested.

The physical maintenance is handled by a separate group, and definitely consumes more man-hours. The CEPS team only handles the print servers and driver issues.

Looks good but it's 1/10th the size and not nearly as flexible. For instance when we shut down one facility we just moved the physical printers into the area the employees would be occupying in the new building and transfered the queue's and DNS assignment to the new locations existing print server, almost no client side changes and very little muss on the printer side, I know the MS solution wouldn't be that easy =) But really going from 6 admins for one campus to one and all for only 1K printers isn't that tremendous, it never should have been that bad to begin with!

As an adiministrator at one of the midwest's largest isps/data centers, I am always looking for better ways of administration. Currently, we use plesk for all our client server administration. However, this costs us a fortune... which is passed on to our clients. I would contribute a lot of this money myself towards a 100% open-source, stable, secure distribution specifically made for web hosting. Features like virtual private servers, a control panel comparable to plesk, and completely secured ssh access would be ideal. In addition, kernel mods to protect security (keeping people out of resources they shouldn't be in) should be done. I could do this myself, but I just don't have the time to keep it maintained myself.

Samba is King of the Free Software World (5, Interesting)

Admit it. With the exception of Apache, Samba is the number one reason that Linux (and BSD, too!) has been able to invade the datacenters of companies the world over.

Without Samba, Linux et al would be in a much less pretty position.

Perhaps we should call it Samba/GNU/Linux? :)

Re:Samba is King of the Free Software World (4, Interesting)

Rick the Red (307103) | more than 10 years ago | (#7543025)

I'm not so sure. Yes, from an administration standpoint it's far easier to make the server (Linux) conform (Samba) to the client (Windows) than it is to force all the clients to conform (NFS) to the server, but if Samba did not exist I believe NFS would have stepped in and filled the gap. Samba has reduced the need for a good open NFS client for Windows, but I'm sure someone would have written one if Samba did not exist.

Indeed, I predict that someone will write one should Microsoft succeed in shutting down Samba (via patents or whatever -- you know killing Samba is on their to-do list).

Perhaps AFS and/or CODA will provide enough diviersion that Microsoft is unable to nail either of them.

What do you suppose will happen when a linux machine tries to connect to one of these servers using smbclient or smbmount?

I love Samba, but in a data center? I guess my idea of a data center is the likes of Rackshack and DataPipe, of which have no use for Windows shares, but I suppose if your data center has a need for thousands of Windows shares... :/

SCP is the way for me.

Missing software (4, Informative)

Anonymous Coward | more than 10 years ago | (#7542697)

I would include Zabbix [zabbix.org] to the Monitoring and Administration section. This is out-of-the-box application that takes care of monitoring of our network consisting of more than 400 nodes. It is not as mature as Nagios or MRTG, but its stability and feature set makes it extremely useful. Native high-performance agents cover most of platforms: Solaris, AIX, HP-UX, MS WIN, Linux, *BSD, OS X. Could be installed in a 5 minutes, this is big advantage over Nagios or OpenNMS.

I did my best to give a high level overview of what there is available and to mention the less known, but equally good tools available.

that's a pretty lame troll. If I had to list all the windows systems that were broken into the last 5 yrs from personal experience, it would far out weigh the Debian incident. The diference between open source and corporations is the Open source community is transparent about it. You're obviously not a system administrator.

In my case, I admin a research lab with 12 workstations and two servers, all running GNU/Linux. I spend no more than 15 minutes per week on routine admin tasks, all of it from home. I can also remotely install any software the researchers need. The only reason I ever need to physically go there is to replenish the office supplies (toner, paper, bsank CDs).

Why NeDi makes Cisco easier to use (0)

Anonymous Coward | more than 10 years ago | (#7542702)

As far as I'm concerned HP switches that have web GUI built in are much better for Medium (up to 500 clients) deployment than Cisco crap. Cisco makes money on training, books etc and I feel that they purporsley make their interface (command line only) hard to use. Even the prompt commands aren't intuitivley named. There is just to much money in the books, and training for Cisco to give it up and the price they pay is that people who need to deploy medium LAN's rather quickly will opt for HP and 3Com. Its good to see NeDi taking that vacum and getting Cisco IOS badly needed...uh...common sense.

The Omega Agency - the truth about New World Order (-1, Offtopic)

Anonymous Coward | more than 10 years ago | (#7542717)

THE OMEGA AGENCY
The Author of this Report is Unknown

They are who people are talking about when one says orders come from "above the President".

The Omega Agency consists of a network set up much like the CIA. There are thousands world-wide who take their orders directly from the ruling council of the Omega Agency. This council consists of 10 to 12 people. George Bush and Alexander C. Haig are two names known to sit on the council of the Omega Agency. The OA is the driving force behind what is commonly called the "New World Order." The OA's office is located at Langley AFB.

They plan to establish their NWO, for lack of a better term, in a time span of no less than 5 days. And they intend to do it without open war.

Recall when President Reagan was shot. Haig made the statements to the press that "I'm in charge now." If you'll remember, he caught a lot of flack for that, and shortly thereafter, he was accused of various things that ruined his name politically. This was done by members of Congress who were aware of his seat on the Omega Agency council, and they feared losing their claim to power. Haig jumped the gun in his statements, and ended up giving up his political position because of it. Had Reagan died, we would have had Bush as President, and Haig as Secretary of State. Two men in power who sit on the OA council. But because of the commotion raised by a few members of Congress, Haig faded into the background rather than risk exposure of his connection to the OA, or of the OA itself.

Recall when the Gulf War started. Bush used the exact words "New World Order" in his speech to the country. He said it several times, that the Gulf War marked the beginning of a NWO. The Gulf War was not a war about oil or the freedom of the people of Kuwait. It was a test of how well multi-national troops under the guidance of the UN would react in a war situation. The same holds true for Somalia and Bosnia. Multi-national troops under the direction of the UN. The Omega Agency controls the UN.

Bush didn't lose the election to Clinton. Bush needed to be out of the limelight of the presidency in order to concentrate on and escalate the plans of the Omega Agency. And in Clinton, they had a stooge who would not rock the boat and who would do what he was told. Notice how quick Clinton has been to commit US troops to UN peace-keeping forces here and there. Notice who Clinton appointed as Secretary of State - Madeline Albright, the UN lady. Notice who Clinton gave federal land to - the UN.

Why the need for a one-world government? The reasoning of the Omega Agency is this: Crime is out of control on a world-wide basis, especially in the US. People are out of control, not taking responsibility for themselves or their actions. Population growth is out of control on a world-wide level. The judicial system of the US is a joke. The political system of the US and most countries world-wide is a joke, corrupted and polluted by greed and power-hungry people who don't care about the population they were elected or appointed to serve. Under the governing body the Omega Agency plans to put in power, this would end. End of trial by jury. End of living off of society and not contributing your fair share. End of taking advantage of others for one's own personal gain. All who are able would contribute to the growth and well-being of the world's society, or they would pay the price for not pulling their fair share.

What is this price? Basically, it will be like this: Those who are able physically and mentally to work will do so. If you have a job/profession at the time that the OA takes over, you will continue in that job/profession. If you are drawing welfare, but are physically able to work, you will work. Personal freedoms to come and go as one pleases world-wide will not change. Basically, the OA doesn't care what people do to amuse themselves, entertain themselves, etc., as long as they are working and contributing to the society as a whole. But there will be zero tolerance of any act that hurts/harms another. Crimes against another or against society will be met with the death penalty, if such crime is of a severe nature such as murder, rape or robbery. What is now considered a felony crime will be punishable by death. What is now considered a misdemeanor crime will be punishable by imprisonment on a work farm for a number of years equal to what the OA considers suitable payback for the said crime against society. These work farms will be in the business of growing food, manufacture of clothing, textiles, etc. People sent to these farms will work for the specified time, or will be eliminated.

There will be zero tolerance for any crime that hurts, harms or infringes on the life of others. Example - a person making threatening phone calls to another will be picked up and sent to one of the work farms. A person committing a drive-by shooting will be punished with immediate death. The policing of the populous will be carried out by men/women who are already chosen and merely waiting for the time when they will go to work for the OA openly. Most are current and/or former military people who worked special ops while on active duty. These people will be responsible for seeking out those guilty of a crime. Once the person is located, they will inform that person that they are guilty of said crime and immediately put a bullet in their head. End of crime problem from that person. Should the person's crime not warrant the death penalty, these Public Security Officers will pick up the person and deliver them to the work farm. If the person resists, they will be shot on the spot. No trial, no jury, no lawyer, no Miranda rights. The Public Security Officer will have the authority to act as sole judge, jury, and executioner of the punishment that the OA declares fits the crime.

Population control will be accomplished by mandatory birth control by all people, men as well as women. Abortion will be freely available. There will be zero tolerance for child-bearing out of wedlock. The institute of marriage is looked upon with favor by the OA. There will be a limit of 2 children per couple allowed. Should one become pregnant after the 2-child limit has been reached, and dispite the use of birth control, then the options will be either to have an abortion or to increase one's work load to compensate society for the burden of the extra child. Birth control and abortion will be completely acceptable in the eyes of the various religions world-wide. It will, in fact, be encouraged and mandatory under some religious doctrines. Recall VP Gore's meeting behind closed doors with religious leaders and NASA officials at the beginning of 1997.

But bringing people under control is not the only reason driving the OA, there is another. The other reason is the extraterrestrials. They are here on this planet, living and working with the OA. These ET's are helping the US with its space program and are working toward devising a plan to restore the planet's environment after the OA takes over. Their main reason for being here is to help the OA put a stop to the violent, out-of-control nature of the human race in general. Why? Because they fear us. They realized when we accomplished the first manned space flight that it was only a matter of time before we moved out into the universe. And they don't want our ways to infest their society. They are helping the OA for reasons of self-preservation of their society. They realized that we are the most violent race in the universe that is on the verge of space travel. And they don't want us spreading our warlike, violent, greedy ways to other parts of the universe and disrupting the order of their societies on other planets. They agreed to help the OA in the advancement of our technology and in the repairing of the damage we've done to the Earth's environment in exchange for the OA's cooperation in changing the ways of this world, bringing us humans into line with the societies of the other planets in the ET's sphere of control in the universe.

The OA has not taken control yet because there are forces within the existing governments of the world that are aware of their plans and oppose them. In the US, these forces are largely centered in the CIA and NSA. The CIA wants world control, but on its terms. The CIA wants to see a more communistic-type government set up on a world-wide basis. While the OA professes to believe in the maintaining of personal freedoms so long as one is a contributing member of society and not infringing on the lives of others, the CIA would rather see a world where all people are controlled in all ways, from what type of job one does to how one worships. It is the CIA/NSA/Air Force that is maintaining secrecy where the ET presence is concerned, not the OA. The Omega Agency, once it comes into power, plans to reveal everything to the people of the world. From the running of drugs to finance the Vietnam War to the presence of ET's on this world for the last 50 years or more. George Bush himself is said to have made the statement that he will personally tell of his involvement in the running of drugs to finance the Vietnam war while he was CIA director. To the OA way of thinking, the ends really do justify the means, and in the case of the Vietnam war, the running of drugs was necessary to finance the operation in that country. Therefore, it was a justified endeavor. Not one to be proud of, but justified nonetheless.

The CIA/NSA/OA all monitor the internet closely. Especially IRC. The Net is described as the most dangerous tool in the world at this point in time because it is uncontrolled. Those who talk about these types of things or carry information about these things on their web sites are closely monitored. In "government talk", orders to "watch" someone translates into instructions to keep track of them by whatever means necessary, and if they cross the line, if they stumble upon the truth of the matter and don't keep their mouth shut, "take them out". This can be done in any way that works without drawing too much suspicion. Such as brakes on the car failing, a random victim in a drive-by shooting, a random target in a store robbery where that person just happens to be shopping at the time, etc. The determination as to whether a person needs to be "taken out" is left up to the discretion of the one doing the watching. It is, in effect, an open license to kill to protect the Omega Agency from public exposure before it has deemed the time is right for it to take control of the planet. In some cases, it is determined that the person in question would pose more of a threat if they died. In such a case, the machinery of the OA goes into action to discredit that person. Character assassination, manipulation of others so as to turn people against the person, campaigns to brand them a disinformation agent, a liar, a mentally unstable person, etc., are put into motion. This has been found to be an effective method of dealing with someone who gets to the truth and doesn't keep silent. In fact, it has been found to not only discredit the target victim but to cast a shadow of doubt and suspicion on others who may have listened to the targeted person.

This plan for the establishment of a one-world governing body, namely what is now known as the Omega Agency, has been in the works for a long time. And it is said that it cannot be stopped. Those who oppose the establishment of the Omega Agency's New World Order, and who cannot be brought into line through persuasion or manipulation will be eliminated as threats to society.

The person from which this information was obtained passionately believes that this plan is the solution to the world's problems. This person is also awaiting the start of a new job - as a Public Security Officer. This is a position this person was trained for and accepted before leaving active military service.

OpenBSD has PF - a really cool packet/nat/authentication/bandwidth limiter/port forwarding system that is really, really, cool

You can do clever things, like allow a certain amount of bandwith for sombody, but if they log in, the bandwith limit disappears.

Or parse the spam blackout litsts and block all incoming packets from them (spam trype networks have more that their fair share of crackers)

All withouht crypic config files.

I *REALLY* hope, for Linux's sake, that after FreeBSD ports PF (to replace their IPF), a Linux port will be forthcoming.

IPTables is just fine for simple firewalls, but PF has a much more sane syntax, and it can handle really complex networks without a headache.

PF is sooo good - it's worth learing a bit of OpenBSD to get it. If you're good at Linux - it will take to half a day to learn all you need to get PF on OpenBSD working, and that includes installing OpenBSD.

It's not hard at all - I came from a Windows background and dident even know VI and it only took me three days to learn enough about OpenBSD to get it working.

It is now official - Netcraft has confirmed: *BSD is dying

Yet another crippling bombshell hit the beleaguered *BSD community when recently IDC confirmed that *BSD accounts for less than a fraction of 1 percent of all servers. Coming on the heels of the latest Netcraft survey which plainly states that *BSD has lost more market share, this news serves to reinforce what we've known all along. *BSD is collapsing in complete disarray, as fittingly exemplified by failing dead last [samag.com] in the recent Sys Admin comprehensive networking test.

You don't need to be a Kreskin [amazingkreskin.com] to predict *BSD's future. The hand writing is on the wall: *BSD faces a bleak future. In fact there won't be any future at all for *BSD because *BSD is dying. Things are looking very bad for *BSD. As many of us are already aware, *BSD continues to lose market share. Red ink flows like a river of blood. FreeBSD is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time FreeBSD developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: FreeBSD is dying.

Let's keep to the facts and look at the numbers.

OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.

Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.

All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS hobbyist dabblers. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.

Fact: *BSD is dead

HP OpenView is what we use to manage thousands of network nodes/hubs. Everything is displayed in a hub/spoke fashion and it easily intigrates with all your equiptment using the SNMP (Simple Network Management Protocol). Not open source, however this tool would be easily adopted by any *nix lover. Everything is easily scriptable, and the GUI is based 100% off command-line apps. So, anything you can do in the GUI can be scripted and alarms can be HIGHLY customized, reports generated on site statistic, you can even view real-time graphs of performance, packet-rate, utilization, etc of any single interface, or multiple interfaces on the same graph.

Another tool of use is the Cisco Transport Controller...we use this to monitor a fiber network up in MA.

I have run both. I like NOT having to mortgage everything to buy the software, then finding out that to run it right, you need to sell your firstborn for the hardware to run it on. For the price of the Sun hardware you need to run OV, you could buy the x86 hardware to monitor and manage a LARGE network.

I used to work as an SE for Cisco, ran a mid-sized ISP's network, owned a computer store, and have run a couple of corporate networks(not bragging, just qualifying my experience, Cisco SE's are highly technical salespeople, some very good some bad). I was an Open Source advocate before I went in, and nothing I saw there changed my opinion. Open View, Cisco Works, etc can all be easily replaced by Open Source tools. These tools do the job as well or better for the cost of a few x86 boxes and your time.

The time factor is still there in the proprietary systems, as you have to learn, configure and maintain them just like the OS tools. There *are* situations where something like Open View is the solution. Probably 99% of the time, you're better off (or at least as good) using the OS tools and contributing back to the community.

I use Nagios, Netdisco, RANCID, and MRTG/RRDTool. I love these articles on Slashdot because I'm always finding links to new tools to try.

Even our management turned down the likes of OpenView and Patrol in favor of it (of course cost helped that as well :). It's got it quirks, and isn't very modular unless you know perl reasonable well, but oob in a cisco network it's great with support for other vendors slowly growing. The developers are supportive via their email list as well. If you're in the need of an monitoring platform and your PHB's aren't afraid of open source apps, NMIS should definately be given a look.

Greetings...

We started using Nagios just over a year ago as something quick and simple while we were building our infrastructure (was still beta in those days). It does the job if you have a small site, but does not scale well. We've just switched over to OpenNMS. It does take a lot more effort to configure and get up and running (especially as we're not running it on Linux), but it's worth it for the additional flexibility and features you get. It helps if you have someone who understands Java for the implimentation as the documentation is a LOT more incomplete than Nagios.

If you understand SNMP and systems monitoring and management then OpenNMS is for you. If not, then go for Nagios.

The system also offers easy integration with event management systems open-source or not. It scales well to a great number of devices.

Plus a brand new version just came out! Get it while it is hot.

Why is there nothing professional? (0)

Hello!

I really do wonder why an OS like Linux, which is very strong in the server market, does not have professional grade network management software?

The mentioned tools are nice toys but nothing more. Why are there no free professional tools which support network management standards such as RMON, SAA, NetFlow, etc in a decent way?

I know that there is StableNet PME and Infovista announced to bring their tools to Linux next year.
So there seems to be a market. What holds back the open source community to develop free alternatives?

my company uses netbackup for all out backup needs we have evaluated many options, but find due to lack of support from other vendors when used with non supported solutions, OSS is not a feasible solution. Our company is a 99.9% solution provider and if something breaks there must be a chain of monetary responsibility. Veritas gives us the support we need and all of our other vendors support netbackup. we do have a couple linux servers but for the most part we are a sun environment, which takes us full circle to supported configurations and a 4 hour service window.
