Error While Loading shared libraries , cannot open shared object file: no such file or directory (Easy solution?)

Tuesday, August 25th, 2009

Have you tried ldconfig yet?

I was working on a website that needed to use libraries from some lib directory on Linux. (it’s not like I understand WHERE To put files or install them yet, eh?)

But, after compiling and installing a program, I got the title of this post as an error message (with my specific library mentioned.)

How did I solve it? ldconfig

If it doesn’t work after that, good luck! MY problem was solved. :P

Recent BIND release has bugs — causes (host map: lookup (domain): deferred)

Monday, August 3rd, 2009

I had a problem on a server where a recent update to Red Hat Enterprise Linux 5 (RHEL5) caused all sendmail mail to be:

  1. Inserted into the queue
  2. Never sent
  3. Never sent with message “(host map: lookup (domain): deferred)
  4. Only sent when the mail queue is pushed ( sendmail -v -q )

I found an old post from 2006 that gave me an idea about what to do when sendmail constantly defers mail. I ran yum update and found BIND had some udpates.

After that, all I had to do was restart the sendmail server and we were good to go.

Good news!
