Debian Etch DVD Set
by Satish Alwani 11 Apr '07

11 Apr '07

Vihan, I currently have it being downloaded, maybe you can do dvd 2 / dvd 3. Its 38% percent done since last night when I started. I think I should have it in the next 2 days odd. I could send you a copy if you want. So i strongly suggest you work on disc 2 first. I am trying to get one of my friends to pitch in and do disc 3 if possible. Once I have all the discs, I can send 1 copy to nagarjuna as well, so he can directly dump it on the server. TIFR is like 10 mins away for me, else courier zindabad. As of the site, I dont think I have seen it since maybe 3-4 years, if not more. I know it has errors, it was written for php3 maybe the beginning of php4. Just running out of time of updating my own stuff. As mentioned, it was for IE5.5, thats pretty old. Regards, Satish

I am going to try and cover the details, briefly - feel free to send questions my way; either onlist or offlist. Also, if you know someone who might be interested,feel free to forward this email to them. Job Spec: While the job is primarily system admin and network management, there is a fair bit of 'script coding' that is also required. Required: The Indian operation is just starting off, so initial work will require a fair bit of remote 'pairing'. We are also going to be spending a few months in India onsite at a client, so expect to be thrown right into the firezone. Technologies that should not be strange to you : Linux ( we are a 100% CentOS / RHEL shop ), Xen, selinux, puppet ( and/or cfengine ), isp grade networks ( routing, packet monitoring and performance testing ), high performance database's, high density storage, large data volume handling. You *must* be able to write scripted code in ruby. Python and php are also handy to know - but not required - since lots of our legacy stuff is done in python and php ( dont ask, the php stuff was before my time ... ). We dont really care about what degree you have. we also dont care if you got 60% or 90% in your exams or what certificates you carry along with you. But, you need to be able to communicate in English, must have atleast a few years of working in a related environment. Common sense and an ability to rationally think are, however, critical! General sysadmin skills are essential ( we will test you on these ). People with a well thumbed copy of 'unix power tools' should definitely apply! All assignments are permanent, full time and come with the govt requirements for benefits etc. Location: We are looking for people based in Pune, Delhi and Chennai as a base. However, for people based in Delhi and Chennai there will be a frequent ( not exceeding 4 working days / month ) requirement to travel to Pune. Type of Employer: The Company is a infrastructure management consulting service, where we offer systems and network services to clients. We have 27 people working full time and 8 people part-time in the UK. And a further 6 people in Australia. Agile and XP practises are a cornerstone of the management style ( in that there is really no management, the entire organisation tree is very flat ). Salary and Benefits: You get paid pretax's Rs.80,000/- a month. We expect you to work 38 hrs per week. We also only work half-days on Wednesdays. There maybe a requirement to work weekends, but only after suitable advance notice ( mostly to handle infrastructure outage that cant happen during the work week ). There is a 6 months trial run period, wherein you get to see what we do and if you want to work with us, and we get to see if we want you working with us. Interview process: 1. Send me a CV. 2. We call you for a quick chat on the phone. ( 20 min ). 3. Have a longer ( 3 hrs estimate ) sysadmin 'pair' session. 4. Fix a time and have a longer ( 1 hr ) developer 'pair' session. 5. People get hired. ( 1st week of June 2007 ) Regards, - - KB [1] - Agencies and head hunters are not welcome to reply to me, we dont and wont hire people through agencies. - -- Karanbir Singh : http://www.karan.org/ : 2522219@icq _______________________________________________ ilugd mailinglist -- ilugd(a)lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/ - -- You see things; and you say 'Why?'; But I dream things that never were; and I say 'Why not?' - George Bernard Shaw -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Red Hat - http://enigmail.mozdev.org iD8DBQFGHFUbXQZpNTcrCzMRAhxyAKCjCiJKzH1CGPqO2QuDbjV5FaKY/gCgnowq PUd/ZKdpxxZ5Epyo5zwQK+E= =Lf74 -----END PGP SIGNATURE----- _______________________________________________ Ilug-cal-discuss mailing list Ilug-cal-discuss(a)list.ilug-cal.org http://list.ilug-cal.org/mailman/listinfo/ilug-cal-discuss -- The KDE Project : http://www.kde.org KDE India : http://in.kde.org Mailing List : http://mail.kde.org/mailman/listinfo/kde-india

Auto-enable usbnet device on link startup
by Siddhesh Poyarekar 10 Apr '07

10 Apr '07

Hi, This is something I noticed while I was playing around with my Triband connection on USB. If I start (or reboot) my router after my computer has started, the network interface for the USB connection is detected but not enabled automatically. I have to manually up the interface. I guess this behaviour is expected under debian since network configuration (upping of interfaces) takes place only at startup through /etc/init.d/networking. Any network devices detected after startup will be configured but not enabled. Shouldn't default behaviour be to simply enable the interface if it is defined as auto in /etc/network/interfaces? -- Siddhesh Poyarekar http://siddhesh.tk

Please link up these how-to-do-it pages in the wsfii wiki also. The resources idea is brilliant and a great boon. Please see how soon we can make this work. Actually, I think from what I heard in Dharamsala, it should be possible for us to 'mesh' into the system remotely wherever we are located, provided we run OLSR locally and tune it to the same mesh. In that case, downloading the resources will be just a hop or or two away.

Is it possible to 'test-bed' this on a non-wireless, perhaps a standalone, device? Can we create ghost nodes somehow? Anyhow, it hardly matters, since the actual test-bed will be available at HBCSE for trials. Vickram ___________________________________________________________ New Yahoo!

Re: [ILUG-BOM] bash proxy settings
by Debarshi 'Rishi' Ray 09 Apr '07

Firstly, may I know what is your ultimate aim? :-) >> I tried the above but now when i try to ping www.google.com >> ping: unknown host www.google.com is what i get. Make sure there is a DNS server that is reachable from your machine. The best way would be to run BIND as a caching DNS server ('# service bind start' for Red Hat systems) on the machine running the proxy server, and configure your machine to use this as the primary DNS (use /etc/resolv.conf). To confirm that this actually works do: $ nslookup gnu.org on your own machine. [ If you can not have a DNS then try: $ ping 199.232.41.10 If this fails, then read on.] Next, make sure you have a gateway that actually forwards the packet from your subnet to the outside world. I have had experience using a 'gateway' which never forwarded anything, so make sure that the sysadmin is not lying and the gateway is actually forwarding the traffic. Checking this is a bit dicey, and depends if there is any firewall that is blocking traffic bound to specific ports and so on. Here are a few things you can try: 1. $ ping google.com 2. Try using an email client like Mutt, Thunderbird, KMail and see if you can send and receive mail or not. If the SMTP and/or POP3 traffic is blocked this would not work. 3. Disable the proxy in the Web browser (eg., Firefox), and try to visit any site. Again if port 80 or 443 traffic is being blocked or not forwarded, this would not work. 4. Try using Gaim. Do not set any proxy, and try to log into Yahoo!, Jabber, or IRC. 5. Try SSH, without using any HTTP proxy tunnelling tool (like Corkscrew). If you have not heard about tunnelling, then most likely you do not have a any such tool. Just do something like: $ ssh foo(a)external.server Knowing your ultimate aim would have been helpful.

Protecting ubuntu against fork bombs
by Chetan S 09 Apr '07

09 Apr '07

Hi all, An old article caught my eye - http://www.securityfocus.com/columnists/308 It talks about the way linux systems react to a fork bomb and surprisingly it is by freezing stiff. Sadly most distros seem to freeze as the limits are meant to maximize performance and not make it secure, even Ubuntu. Can someone shed light on what knobs/limits to tweak to deal with this "problem" ? regards, C
