problem sending/recieving mails
by maina＠linuxmail.org 02 Nov '10

02 Nov '10

Hi all, I ave setup a CentOS server to act as LAN gateway and also as a transparent proxy server but all client "passing through" that server are enable to send or recieve mails. The mail server is host on the same LAN running mdaemon, both servers are on private IP block(192.168.0.0/24). Am using cisco router to do port forwading for mailserver(25,110,143) ports. If i eliminate CentOS box and direct traffic direct to cisco router everything works. My question is why is it when i use CentOS box as LAN gateway clients are unable to send/receive mails? I ave done nating on that box. Centos 5.5 full updated.

I have updated certain packages through applications->system tools->software updater. Is there any command by which I can know which softwares I had updated?

The graphics controller is Intel Corporation 82G33/G31 Express Integrated Graphics Controller This problem is occuring since the time I have updated firefox. Also whenever I open facebook the system hangs and sometimes logs out. But sites like yahoo, gmail, orkut are opening.

grub irritants
by m.roth＠5-cent.us 01 Nov '10

01 Nov '10

It appears that if I do anything to grub.conf, say, take out the rhgb quiet, after every succeding kernel update, I have to manually edit grub.conf, because the kernel update - maybe the post install script? - will set the default to be the previous kernel. Has anyone got a solution to this, so that a kernel update will give the new kernel as the default? mark

Geany plugins out of sync
by Eduardo Grosclaude 01 Nov '10

01 Nov '10

I'm intending to do some version control, hence looking for some plugins. Geany and geany-plugins packages in Rpmforge seem to be out of sync: Name : geany-plugins Arch : i386 Version : 0.18 Release : 1.el5.rf Name : geany Arch : i386 Version : 0.19.1 Release : 1.el5.rf When both are installed, geany claims that plugins are not "binary-compatible". Frank's own hosted geany RPM (http://www.melvilletheatre.com/articles/el5/geany-0.19.1-1.i386.rpm) is even newer, but no geany-plugins there. Any chance for this to be repackaged? Or, some quick & dirty workaround? Thank you very much in advance! -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

I have CentOS5.3 installed on the system. I have updated firefox to firefox-3.6.11-2.el5.centos. While doing any work on the internet, suddenly the system logs out. What can be the problem?

Possible to reboot a system after kickstart installation without pressing a key?
by Sean Carolan 31 Oct '10

The subject just about says it all - I'm wondering if there is a way to do a completely hands-off installation, including the reboot at the end, without "Press any key to continue"?

migrating users to openldap
by Tim Dunphy 31 Oct '10

31 Oct '10

I noticed that when I migrated my users with the migrate_passwd.pl tool from PADL it didn't migrate the actual passwords (just the rest of the posixAccount info). I think I need to set the EXTENDED_SCHEMA variable and then try running the tool again. does anyone know what this should be? I actually thought there might be a migrate_shadow.pl tool that could accomplish this, but there doesn't appear to be anything like that among the PADL migration tools. So in short the user info is there in LDAP but no one can log in because all the password fields look like this: userPassword: {crypt}* Here is a more complete user entry that is currently in the system: 73 uid=bluethundr,ou=summitnjops,ou=staff,dc=summitnjhome,dc=com uid: bluethundr cn: Timothy P. givenName: Timothy P. sn: Dunphy objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount loginShell: /usr/local/bin/bash uidNumber: 1001 gidNumber: 1002 homeDirectory: /home/bluethundr gecos: Timothy P. userPassword: {crypt}* thanks in advance for any tips you can share that will get this working! -- Here's my RSA Public key: gpg --keyserver pgp.mit.edu --recv-keys 5A4873A9 Share and enjoy!!
