sshd hack
by Chris Mauritz 12 Mar '06

12 Mar '06

I'm not really a programmer and I recently came across this hack to insert a short sleep statement into auth-passwd.c within sshd. It seems to quickly confuse automated dictionary attacks. I've moved sshd to higher ports but apparently the cretins are now scanning to look for that and attacking on whatever port sshd shows up on. Anyway, the link to the hack is here: http://www.aerospacesoftware.com/ssh-kiddies.html Just wondering if any of the wizened programmers out there can think of any reason why this would be a bad thing to do. Cheers,

Q's about switching from sendmail to postfix
by Joe Klemmer 12 Mar '06

12 Mar '06

Running CentOS 4.2 with all updates. I've been using sendmail for my MTA since forever. I've grown used to it and I can make it do what I want it to. However (there's always a catch, isn't there)... Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to everyone. Additionally, I am on the word-a-day list and have noticed that occasionally I don't get the word for that day. At first I thought it was just me. My .procmailrc is a horror to look at and I've got some fairly aggressive anti-spam stuff going on. But my mother has mentioned this problem, too. (I have my whole family setup with email on my server, good son that I am) Anyway, I want to try swapping out sendmail for postfix to see if that makes any kind of difference. Now, I promise to hit the HOW-TO's and FAQ's and google/A9 myself blue in the face, but if someone has already done this could you kindly post a quick message with any "gotchas" you found or any config issues you ran into it would be greatly appreciated.

Latest kernel seems to have found my second NIC
by Bart Schaefer 12 Mar '06

12 Mar '06

I just yum-installed the 2.6.9-34 kernel RPMs and rebooted, and lo and behold, my other onboard NIC is now detected, after a fashion. /etc/sysconfig/hwconf now has entries for: device: eth0 driver: forcedeth desc: "nVidia Corporation CK804 Ethernet Controller" device: eth2 driver: sky2 desc: "Marvell Technology Group Ltd. 88E8053 Gigabit Ethernet Controller" The device/desc lines for both were always there, but previously the device now identified as eth2 had neither a driver assigned nor a recognized hwaddr, and if I disabled either device in the BIOS, then the remaining enabled device would take on the same driver/hwaddr that has otherwise been listed for eth0. The odd thing still is that according to the motherboard manual, the two onboard NICs are identical, so I still don't know why one shows up as nVidia and the other as Marvell. If I wasn't afraid of messing up my working configuration I'd try deleting them both and letting them be rediscovered, just to see if anything else changes.
