Postfix setup
by Austin Einter 13 Mar '13

13 Mar '13

Dear All I am planning to setup mail server for my domain. Which one is preferred postfix or sendmail. I came across a link * http://ostechnix.wordpress.com/2013/02/08/setup-mail-server-using-postfixdo… * for postfix mail setup. It says, Prerequisites: - The mail server should contain a valid MX record in the DNS server. Navigate to this link how to setup DNS server<http://ostechnix.wordpress.com/2013/01/25/setup-dns-server-step-by-step-in-…> . - Firewall and SELinux should be disabled. I have disabled iptables as my m/c is behind the firewall. It says I need to disable firewall. Is it really required. Kindly let me know. Best Regards Austin

CentOS 6.3 - fail2ban not working properly + workaround
by SilverTip257 13 Mar '13

13 Mar '13

I recall others on this list are using fail2ban to block brute force login attempts. Packages are from the EPEL repo, so I'm just sharing some knowledge here. For about two months now I've had a CentOS 6.3 box (web host) in production that occasionally is ftp brute forced. Oddly enough fail2ban wasn't nabbing the perpetrators. I found that the iptables chain for VSFTP isn't created for one. I have finally come to find [0] that indicates there's a problem with the inotify backend. Setting backend=gamin in /etc/fail2ban/jail.conf gives me the iptables chain I expect to find and one blocked host. Hope this is helpful to somebody until a new version is commited to EPEL. <quote> yarikoptic: ok -- that point was not yet good ;) now (0.8.6-95-gc0c1232) that branch seems to work just perfect. If I hear no complaints or do not see problem with my instance -- I will merge it into master tomorrow, thus closing this issue </quote> [0] https://github.com/fail2ban/fail2ban/issues/44 ---~~.~~--- Mike // SilverTip257 //

6.x - USB key
by m.roth＠5-cent.us 12 Mar '13

12 Mar '13

I just had to rebuild my USB key for a generic install (got to do that for a drive to send with the system back to the OEM for repair, y'know). This time, I used unetbootin, which took a while to build the key, and worked *almost* well. The two annoying hangups: it took a *long* time to extract the packages and put them all on the USB key, looking like a repo... EXCEPT that during the install, anaconda *demands* the .iso. I went back, deleted /mnt/usb/Packages, since it's only an 8G key, and just copied DVD 1 onto it. anaconda stopped, asked me where, I told it, and it happily went on its way. Then, it doesn't give you any kind of default grub.conf Oh, well. Drive's built and boots. mark

CentOs 6.4 and video drivers
by Yves Bellefeuille 12 Mar '13

12 Mar '13

The release notes for CentOS 6.4 state as follows: > With this release the ABI for the X.org video drivers changes, > possibly resulting in a failing X-Session. If you are running 3rd > party drivers - i.e. vBox addons, nVidia, ATI or ELRepo - you need to > ensure a compatible driver is loaded. I use flgrx from ELRepo. Does this mean that fglrx is now incompatible with CentOS? Yves Bellefeuille
