[CentOS] Cannot See Login Screen Anymore !!
Hi CentOS community Friends, It is CentOS 6.2 x86_64 machine, i have upgraded few packages using "yum -y update", after the reboot machine does not show login screen, i have allowed enough time to show the screen that are about 2 hours. booting process does complete, it just hangs when it is about to show the screen. i tried to check by doing ssh for warring/error logs. nothing serious was there. but when i did the ssh to the server then i saw the following error. Prior to the upgrade machine was just okay.. ) MacBook-Pro:~ prabhpal$ ssh -l mike 41.211.25.233 mailer@41.211.25.233's password: -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied Thanks / Nath ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi, it seems that you want to read user & pass info from the MySQL DBMS.
Problem 1 seems to be permission issue, since it cannot write.
Problem 2 is misconfiguration related mysql with dovecot. SEE RED TEXT
because it is working, i have the following in "/etc/dovecot.conf" and
"/etc/dovecot-sql.conf", that concern to authentication. Either you have
not provided the full information or cross check your configuration.
configuration is missing that i feel.
*" /etc/dovecot.conf"*

> args = etc/dovecot-sql.conf

> userdb sql {
> args = /etc/dovecot-sql.conf
> }
*## Authentication processes*
auth_username_chars =
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@
auth default {
mechanisms = plain login
passdb sql {
args = /usr/local/etc/dovecot-sql.conf
}
userdb sql {
args = /usr/local/etc/dovecot-sql.conf
}
*
" /etc/dovecot-sql.conf"*
driver = mysql
connect = host=localhost dbname=postfix user=postfix password=your_pass_word
default_pass_scheme = MD5
password_query = SELECT password FROM mailbox WHERE username = '%u'
*user_query *= SELECT maildir, 125 AS uid, 125 AS gid,
CONCAT('*:messages=1:bytes=', quota) AS quota_rule FROM mailbox
WHERE username = '%u' AND active = '1'
