That is the problem with these wizards - only a wizard can use it. You need to setup static ip and enter the ip manually Here is my /etc/network/interfaces file (this is the file which holds the ips etc in Debian GNU/linux). auto eth0 eth1 iface eth0 inet static address 192.168.0.1 netmask 255.255.255.0 network 198.168.0.0 broadcast 198.168.0.255 gateway 198.168.0.1 You will have to find out where your file is (afaik in RH it is /etc/sysconfig/network-scripts/ifcfg-eth0) > Do I need > to manually turn on DHCP or something ?

The modem works peacefully under Win98 and XP Get one thing absolutely clear here and now. Check first if some hardware is supported under GNU/linux. If it is not dont buy it. The specs to write the drivers are not made available cause the mfg wants to fleece u in cahoots with crooked companies like m$. And if it works under windoze stick to that and suffer the consequences. Also you should switch to debian it is the easiest to configure. rgds jtd

Hey guys, we're looking for MySQL ops folks. Skills required: 1. Ability to understand the instructions in this mail 2. You gotta rock* at mysql administration (sorry, if you pop, hip hop, rap or disco, you're not good enough) 3. Experience on FreeBSD is a major plus, linux or other Unix sufficient You'll have to move to Bangalore (or stay there if that's where you already are). Send your resume to me as an attachment in plain text or html format. Include significant differences between MyISAM, InnoDB and MaxDB in your email. Do not copy-paste from a website. *rock: you must be really really good. Know the MySQL administrators docs inside out, be able to work with MyISAM as well as InnoDB and recommend when to use which. Be able to backup a db with minimum downtime (If you can do it in zero downtime then we want to talk to you).

Vulnerability in RHEL 4 kernel: FYI
by Rakesh 24 Feb '05

24 Feb '05

I recently came across a vulnerability in the recently released RHEL v4 (http://www.securityfocus.com/bid/12599/discussion/). Would like to advice guys who have bought or planning to buy the RHEL v4 to see into the Redhat advisory RHSA-2005:092-14 to address the issue. Red Hat Enterprise Linux kernel is reported prone to multiple vulnerabilities. These issues may allow local attackers to carry out denial of service attacks and gain elevated privileges. The following specific issues were identified: The Red Hat Enterprise Linux kernel is reported prone to two local denial of service vulnerabilities. Another issue affecting the Red Hat Enterprise Linux 4 kernel 4GB/4GB split patch can allow local attackers to read and write to arbitrary kernel memory. These issues are reported to affect the Red Hat Enterprise Linux 4 kernel. -- Regards, Rakesh B. Pal Emergic CleanMail Team. Netcore Solutions Pvt.

Do I need to manually turn on DHCP or something ? I noticed that after the Wizard ran, the m/c on startup shows a new error on the console stating unable to bind IP or something. + what is to be done if my modem is not even detected by Linux. The last time I checked, the thing was supported until RHL 7.1 Why was this model singled out like this ? The modem works peacefully under Win98 and XP My current Setup is M/c 1 : winXP with a lan card M/c 2 : Win98 with a lan card and a dial up modem. RHL 8 on dual boot I eventually want to remove Win98 from m/c 2 provided that everything that used to work still does. Regards, Gishu -- http://mm.ilug-bom.org.in/mailman/listinfo/linuxers

Moot point. Doubt anyone running windose will ever have the time from patch-format-reinstall to actually do a case study in anything. Why cant they hire coders in lieu of case study guys to actually fix the sh**. Ahh i forget if they do fixit who will buy longhorn or whatever is the next version extruded from that pandora's company.
