gdm error after while…..

ns2 ~ # /usr/bin/gdm

/usr/bin/gdm: error while loading shared libraries: libdirectfb-0.9.so.25: cannot open shared object file: No such file or directory

Revdep-rebuild should find out the problem for you, the most obvious reason whyit might not is if a previous run of revdep-rebuild did not complete and thetemporary files were still present.  Please try running “revdep-rebuild -i” toensure that the temporary files are cleaned out.  If you do this before trying to re-emerge totem-pl-parser, you can test whether it spots, it and then againwhether totem-pl-parser fixes the problem.

If after you’ve got the results the problem hasn’t been fixed, orrevdep-rebuild wasn’t correctly finding the issue, then please feel free to reopen this bug…  5:)

Install SPF to CentOS Postfix

In computing, Sender Policy Framework (SPF) allows software to identify messages that are or are not authorized to use the domain name in the SMTP HELO and MAIL FROM (Return-Path) commands, based on information published in a sender policy of the domain owner. Forged return paths are common in e-mail spam and result inbackscatter. SPF is defined in RFC 4408. from wikipedia

Install require packages

root@ns99 ~ # yum install perl-Mail-SPF

Get SPF module from http://www.openspf.org/Software Newest at this time is 2.007 and Install SPF module

root@ns99 ~ # wget http://www.openspf.org/blobs/postfix-policyd-spf-perl-2.007.tar.gz root@ns99 ~ # tar zxvf postfix-policyd-spf-perl-2.007.tar.gz root@ns99 ~ # mv postfix-policyd-spf-perl-2.007/postfix-policyd-spf-perl /usr/local/lib.

add following line to /etc/postfix/master.cf

policy  unix  –       n       n       –       0       spawn
  user=nobody argv=/usr/bin/perl /usr/local/lib/policyd-spf-perl

add following line to /etc/postfix/main.cf

smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, check_policy_service,
check_policy_service unix:private/policy
policy_time_limit = 3600

Add SPF record to your DNS. SPF record can be wizardly made from  http://old.openspf.org/wizard.html?mydomain=example.com&submit=Go%21

spf01   IN TXT “v=spf1 +ip4:xxx.xxx.xxx.xxx/24 ~all”
spf02   IN TXT “v=spf1 +ip4:yyy.yyy.yyy.yyy/24  ~all”
