Change web hosting

My previous web hosting gone out of business, I guess. Their frontpage shows that "This account has been suspended". WTF. Luckily, I still have all my web files and database. So, after reading some forum, I decided to move to GoDaddy. The plan is good. I got $60 for two years.

The only backstep is that they don’t provide ssh access for shared hosting. So I have to transfer all the files using FTP. What a pain in the ***. It took me 8 hours to transfer 50MB of my web. Furthermore, they limit their phpMyAdmin to 2MB only, so I (again) have to transfer my sql file and let them install it for me.

Well, at least they have a good support personnel.

Migrating Mailserver

My new mailserver experienced hardware problems related to harddisks and/or motherboard. The problem first occured in /var/log/messages as command timed out on the ata disk.

Then later, Ext3 was experiencing aborted journal, which then make the filesystem read-only. This promptly caused problem with the mailserver activity since people couldn’t send/receive mails anymore.

At first, rebooting the machine would temporarily solve the problem, but it became more often everyday and worsened, I couldn’t even log into the machine anymore.

So, we decided to move back the mailserver to the old machine temporarily. We need to backup this:

  1. The vpopmail database in mysql.
  2. /var/qmail/
  3. /home/vpopmail/
  4. /var/log/qmail/
  5. /var/log/maildrop/
  6. /etc/mail/
  7. /.spamassassin/
  8. /etc/tcprules.d/
  9. /usr/share/toaster/mrtg/
  10. /etc/httpd/conf/httpd.conf, along with any htaccess password file.

The cause of the problem is still unknown, but I suspect these:

  1. Electrical surge from an old UPS used by the mailserver.
  2. The temperature of the server room is too cold. 18 degree celcius? I need to check the operational temperature for the harddisk.

Note on Installing Kannel on Centos4.2

I encountered a problem when tried to install kannel on centos4.2. The kannel package is available from dag repository.

This is my dag.repo:
#dag
[dag] name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

When I yum install kannel, it got error:

From the Centos list, someone encountered similar problem, but he got it when he wanted to upgrade from centos4.1 to 4.2. Mine is installing on 4.2.

So, since the error is only regarding missing library, and since he said that sqlite from different version can be installed along side, I made a decision to force install sqlite from dag:
rpm -ivh –force sqlite-2.8.16-1.2.el4.rf.i386.rpm
Preparing…                ########################################### [100%]
   1:sqlite                 ########################################### [100%]

In /usr/lib, now there is the needed library: libsqlite.so.0.

And then I used yum to install kannel:

Then I plugged the gsm modem in:
