Ask Slashdot: Which Router Firmware For Bandwidth Management?

kbahey wrtbwmon (104 comments)

If you want to know how much each device uses by hour, day, month, then you need wrtbwmon.

It is a simple shell script that uses iptables, and runs on OpenWRT just fine.

wrtbwmon shows a graph for each device by MAC address. if you configure OpenWRT to use a fixed IP address per MAC address, then you see the device name that you assign on all graphs.

The original is here. There is also this fork.

I have modified it to run off of a USB memory stick, and store its data there as well. It does not use much storage, barely 85 to 100 kilobytes per day. So even an old 512MB USB stick should last for many years.

RCMP Arrest Canadian Teen For Heartbleed Exploit

kbahey Security agencies told the CRA (104 comments)

According to the statement on the CRA web site, it was security agencies that told the CRA that 900 SINs were stolen:

Regrettably, the CRA has been notified by the Government of Canada's lead security agencies of a malicious breach of taxpayer data that occurred over a six-hour period. Based on our analysis to date, Social Insurance Numbers (SIN) of approximately 900 taxpayers were removed from CRA systems by someone exploiting the Heartbleed vulnerability. We are currently going through the painstaking process of analyzing other fragments of data, some that may relate to businesses, that were also removed.

So, are the security agencies monitoring traffic to government web sites, so that they are so specific? What else are they monitoring?

Double Take: Condoleezza Rice As Dropbox's Newest Board Member

kbahey Condy's words still fuel conspiracy theories (313 comments)

Back in 2008 when Israel attacked Israel because of foolish Hezbollah misadventures, Condoleezza famously said:

What we're seeing here is, in a sense, the growingâ"the birth pangs of a new Middle East, and whatever we do, we have to be certain that we're pushing forward to the new Middle East, not going back to the old Middle East.

Here is the source.

To this day, the words "New Middle East" is believed by a vast majority over there as a USA conspiracy against Arabs/Muslims. When the 2011 revolution broke out, the first explanation by many was : "It is the USA conspiring against Mubarak, Egypt, Arabs, ...etc."

Now both sides of the political divide in Egypt (pro-Military, pro-Muslim-Brotherhood) point to the other party as an accomplice or agent for that conspiracy.

It is so powerful and pervasive .. no thanks to that ideologue of a Condy ...

Dyn.com Ends Free Dynamic DNS

kbahey Re:If you have Linode, then it is free ... (242 comments)

You did not understand what I said ...

First, I was giving an example of how to get free Dynamic DNS if you already host with Linode. No extra service needed.

Second, the script I described and included the source code for, runs on OpenWRT. Since OpenWRT is a router it does not need to run a remote script (PHP or otherwise) to know what its external IP address is.

Finally, the PHP script was if you do not have OpenWRT, and want to have the equivalent functionality with Linode from a Linux machine that is not the router, inside your network. In this case, you need to get the external IP by running a script on your Linode VPS, then updating Linode's DNS using curl command.

Clearer now?

Dyn.com Ends Free Dynamic DNS

kbahey If you have Linode, then it is free ... (242 comments)

If you have a Linode VPS, then you do have free Dynamic DNS. All you need is a script to update the relevant subdomain.

Here is a script that does it for an OpenWRT router.

Using Linode Dynamic DNS with OpenWRT

If you don't use OpenWRT, you can still use any Linux box behind the subdomain, but you need to setup a small "what is my IP" script outside your subdomain. For example, simple script like so will do the trick:

<?php
print $_SERVER['REMOTE_ADDR'] . "\n";
?>

Now, you need to change the OpenWRT script above to contact the server that has the PHP script, and get the public IP address of the subdomain.

Ask Slashdot: Can an Old Programmer Learn New Tricks?

kbahey No, never too late ... (306 comments)

No, it is never too late for someone who is willing to learn ...

My career spans some 30 years, and I did reinvent my skills every now and then.

I changed careers to computers in the mid 1980s, from pharmacy, of all things. Started with playing around with a Sinclair ZX Spectrum. A year later, I got a job doing programming in COBOL on mainframes, along with PCs. A couple of years after, it was finally UNIX, where I realized this is the system for me. Some years after, it was Linux. Several years after that, it was LAMP (Linux, Apache, MySQL, and PHP).

Now I do consulting on open source exclusively, as a small business owner.

Just have to learn new things every now and then, and do actual projects with them.

Russian State TV Anchor: Russia Could Turn US To "Radioactive Ash"

kbahey Nutcases everywhere ... so what? (878 comments)

There are nutcases everywhere ... so what ...

Here in Canada we have them too. For example, this is a Canadian member of parliament who said military action may be needed against Russia.

But when you know Anders' views, you will not be surprised. He is a Conservative MP, who voted against granting Mandela honorary citizenship, calling him a communist and terrorist.

Here are the rest of his extreme views.

So, one news anchor spewing nonsense is not surprising.

What matters is not letting these type of pro-escalation voices drown out a more level headed reasonable approach ...

Ask Slashdot: Local Sync Options For Android Mobile To PC?

kbahey Seconded ... (146 comments)

Seconded.

I use FolderSync Lite, which is free, and assign certain folders to be synced using SFTP to a Linux server. Any Linux server running OpenSSH has SFTP built in with no extra parts needed.

The folders are mainly the camera, screenshots, ...etc. You can tell it to only sync when there is WiFi, and when the phone is powered on.

EA's Dungeon Keeper Ratings Below a 5 Go To Email Black Hole

kbahey Re:Works for Slashdot as well... (367 comments)

Zero point?

Did you read Slashdot's editorial response? They don't hear us: long time members, moderators and contributors to the site.

They are determined to kill Classic and march along with beta. This means Slashdot as we know it ceases to exist. People are organizing to create an alternate Slashdot site already.

Here is what I wrote as a response to their post.

===
Dice can't see it, since must be new here (he he)...

The most loyal long time most avid readers of Slashdot, are not trolling the site, in protest of the failed beta. Never thought I would see the day ...

Where is GNAA, Natalie Portman grits, and frist prost when you need them!

Let me explain ...

I have been a regular visitor to Slashdot for around 15 years. For that, I get the checkbox to disable ads, though I browse with Javascript disabled so my browser does not slow down.

I come here for the discussions, and often read comments at +5, changing that only if I find a discussion interesting and warrants reading at a lower level.

The new beta uses JQuery for the comment threshold selector, and changes that on the fly. This means all the comments are loaded, but not visible, and processing any page with considerable number of comments will slow down MY computer! If I have a few tabs open to read later, my computer will be unusable.

What is worse it that they require you to click on the slider on every article to change the threshold! This is just insane!

If they insist that I enable Javascript to browse the site at the threshold I want, then they will lose me as a long time. I imagine that others long timers will hate the site too.

Dice have to remember that this site has two unmatched features, interlocked: a moderation system that is good at cutting down the trolling, spamming, and noise, and a comment section that is frequented by many people who are passionate about technology and other nerdy stuff.

If they wanted to intentionally ruin the site and drive people away, they would not have done any worse than what they are doing now.

If they manage to aggravate a lot of their users, the comment section will no longer be attractive to the audience. People are discussing alternatives already. Wisen up and kill the beta NOW!

And no, it is not about look and feel only. Lipstick on a pig does not make it pretty.

See the discussion here about CSS vs Javascript.

I wrote the above in a feedback form that I filled a while ago, and I am emailing this comment to their feedback@slashdot.org. Please send them feedback too.

Paul Vixie On the Unevenly Distributed Intelligence of Internet Infrastructure

kbahey Re:Classic Slashdot (96 comments)

Dice's management have already made up their mind, and they are determined to kill Classic Slashdot. They may entertain some changes to the beta, but they will not kill it.

They will not setup a poll, because they have already decided. Done deal.

The part I am not sure of, is: do they know the extent of revulsion against beta? Or are they just chalking it up to a vocal minority, trolls, and whatnot?

First transmission of Bitcoin over public radio

kbahey kbahey writes  |  about 3 months ago

kbahey (102895) writes "A local radio channel in Kitchener-Waterloo was able to successfully transmit Bitcoin over radio waves. This makes what is believed to be the first known transmission of the digital currency by a public radio station. A series of beeps were played over the air, and listeners were asked to use an app known as chirp.io to decipher a code produced by the sound. Chris Skory of Rockland County, New York was the winning recipient, and unlocked 0.05 Bitcoin worth about $40. The Bitcoin was donated by Waterloo start-up Tinkercoin and a local Bitcoin enthusiast.

Those local enthusiasts engage in local buying and selling of Bitcoin."

Bono wishes movie moguls succeed against downloads

kbahey kbahey writes  |  more than 4 years ago

Khalid Baheyeldin writes "In his New York Times op-ed column, Irish singer Bono, otherwise noted for his humanitarian efforts expressed dismay at losses music artists incur from internet downloads. He notes that "we know from America's noble effort to stop child pornography, not to mention China's ignoble effort to suppress online dissent, that it's perfectly possible to track content". He then goes on to wonder "perhaps movie moguls will succeed where musicians and their moguls have failed so far, and rally America to defend the most creative economy in the world, where music, film, TV and video games help to account for nearly 4 percent of gross domestic product.""

Canadian voting tech enters American politics

kbahey kbahey writes  |  more than 5 years ago

Khalid Baheyeldin writes "The CBC is reporting that a so-called "next-generation Canadian voting technology" is making its way on to the American political stage.

The secure electronic voting system based on cryptographic principles was conceived at the University of Ottawa about two years ago. The makers claims that Scantegrity's electronic voting technology is designed to provide end-to-end verifiable voter results.

From the article:

The key problem in automated voter technology is ensuring voter anonymity — by unlinking ballots from citizens' identities — while still providing them a way to check that their ballots have been cast properly.

"Scantegrity gives voters a privacy-preserving receipt," [Essex] says. "It doesn't show other people how you voted, but it does allow you to have a way to check to ensure your vote gets counted."

The concept is similar to hotels that issue confirmation numbers, he says. "You can go online and look up your confirmation number, but it doesn't display your room number."

Another key security feature Scantegrity provides is software independence, Essex says. "This means if an error is made in the software, that mistake can't go through the process undetected. There's a software tool that does a cryptographic self-audit to verify computations."

Scantegrity is designed as an add-on to existing optical scanning voting systems such as Diebold, he says. But the difference is that mathematical formulas are used to generate the randomized confirmation codes issued to voters, and cryptographic principles are used in the software to tabulate and verify the results.

RedHat's Bob Young on Canada's copyright bill

kbahey kbahey writes  |  more than 5 years ago

Khalid Baheyeldin writes "Red Hat founder Bob Young voiced concerns on Canada's Bill C-61. The bill, among other things, would make it illegal to modify or remove any device or software fitted with a technical protection measures (TPMs).

Young said "the proposed bill will cater too heavily to the content industry and not to the engineers and software developers that are going to be most severely impacted by the new laws. The proposed anti-circumvention legislation, he said, is similar to making the use and ownership of screw-drivers and pliers illegal because they can be used to commit crimes such as burglary."

Bob Young is now CEO of on demand publishing Lulu, and owner of the Hamilton Tiger-cats."

kbahey kbahey writes  |  more than 7 years ago

Khalid writes "The Canadian Press is reporting that after a 72-second surveillance tape was posted on Youtube, a suspect in a stabbing murder case has surrendered.

Consequently, police in Hamilton, Ontario say they now consider YouTube to be an effective crime-fighting tool.

From the article:
Police say the clip didn't lead to any witnesses coming forward, but the extra attention paid to the case because of the use of YouTube likely encouraged the suspect to turn himself in.
Hamilton police believe it's the first time law enforcement has used YouTube as a direct investigative tool.
Staff Sgt. Jorge Lasso, who made the decision to post the clip online, says the video had registered some 34,000 hits as of Thursday.
