The CDs should be just fine as far as booting them goes. You need to burn them as an image with your burning software and boot any if the CD-1 or DVD-1 images. If your machine does not boot from CD, you can create a pen drive boot using bootdisk.img from here: http://vault.centos.org/4.9/os/x86_64/images/ (or i386 instead of x86_64) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos Thanks Johnny.

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*
passdb sql {
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
}

}

Thanks, Neil What you should do is run postconf without paramaters to a file and inspect that. In my case e.g. myorigin is set to $mydomain, but mydomain is set to the correct value. Good lcuk Adrian Command will show default values set in postfix: postconf -d | grep myorigin.
