firewall setup for ISP
by sel 20 Jan '05

20 Jan '05

Hi all, I am planning a firewall for an ISP setup,where I can filter the well known viruses and protect my N/W from intrusion and can be easily monitored and edited. I am planning for iptables as it is much more versatile,can u suggest me to how to go 'bout with the iptables as I'll have to open almost all the ports and block the ones which are prone to viruses and secondly how do I block the common viruses and is it possible to block spam and mail related viruses through iptables(I already got scanners installed on the mail servers) or suggest me with some better alternative or a package for this kind of setup... Thanx in advance, Regards, Sel (The future is Open,the future is bright) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

If you have some app that has no GNU/linux equiv you can use colinux. http://www.colinux.org/ Colinux allows you to run GNU/linux and windows at the same time like VMware. unlike vmware tho it is free and opensource - could not locate any licence on the site though. rhds jtd

>I am also helping a friend of mine to setup a cyber cafe, they want >users to be disconnected after an hour's usage. Squid does not have this >feature to best of my hacking. Any thought on how to impliment this? The best way to do this is to use IPtables to block the specific client ip after a certain interval of time. As far as someone changing ip on windows machine use dhcpd to alocate a specific ip to specific mac address. Derwyn

The specs are simple and permits a simple design. > adaptible time keeping machine made the PCO booth business sell > like hot cake ! Why can't this happen with Internet ? My dear friend surfing the internet involves far too many complex technology bits too enumerate here. But if you scaled the cost of an ISD call (1200 bytes / s * Rs.0.33 * 60 sec = Rs.20) to that of an internet page (30Kbyte / 1200 * 0.33) you would be paying Rs.8.25 per page. So technology has simplified things to the point where costs and complexity (click to connect) have reduced to negligible levels. This arg is ofcourse a bit oversimplified but valid nonetheless. So please do read up a little before comparisons. > >- i (foolishly?) told him that linux will > >liberate him Have u specified the problem? (or rather i have not understood the problem although i am following this thread). dhcp (leases) + bootp + Remote desktop + diskless client - windoze + employee policy Basically redistribution of costs from individual machines to the server.

Cyber Cafe

> That doesn't stop them from changing the IP. They just have to > change the client settings from dhcp to static ip. 1) When u load any OS do u allow the user permissions to change the ip or mac address if so then the setup and policy is bad. Admin user rights are usually kept with the owner or admin. 2) Also if u use squid and if he does change the ip would he not have to know ur network ips range 2 do that. So if the IP is out of range in squid would he still be able to log on to the net. Derwyn

Freebsd/Freesbie CDs
by Soumen Dass 18 Jan '05

18 Jan '05

Anyone having Freebsd 5.3 (this is the latest Production Release, I presume) CDs available? Or know a shop in Mumbai where I can buy them? I saw the screenshots of Freesbie on osdir.com... they look AWESOME!! Anybody tried that? I'm pretty satisfied with Fedora Core 1. But I must find out what makes the Freebsd users go ga-ga about their system's virtues :) On a related note, I have made a 4.3G primary partition for Freebsd. Is this enough space for a typical home user profile? I'm not into heavy gaming or GBs of music etc... Infact one of the aims of this exercise is also to have a visually appealing but light, fast & fully functional desktop with decent amount of free space. Already using FVWM on my Linux setup, so you might have guessed that I'm the greedy type ;) -- Soumen Dass [Registered Linux User # 272639 - Linux nova 2.4.22-1.2115.nptl i686] "One Architecture, One OS" also translates as "One Egg, One Basket".

I had my backups in the file 'backup.tar' earlier in 2004, using the command : tar -cf backup.tar `ls -A` I needed to backup again, so (in 2005) I used the comand : tar -uf backup.tar `ls -A` But now when I try to extract from the file, using - tar -xf backup.tar I get the error : tar: This does not look like a tar archive tar: Skipping to next header tar: Error exit delayed from previous errors The archive manages to extract the files modified/created only in 2005. I dont remember getting any error messages while creating the tar file. Any pointers ?

The colinux uses either winwoes drivers natively or linux drivers natively (if i have understood things correctly).
