[tac_plus] Tacacs problem with packets

[Jetmir Sulmina]

Hi Heasley,

The configuration file is as in attach. The log file is tac_plus.log is very big to be sent via my mail. The portion of log I sent you was from that file (if you refer to tac_plus.log file). If you need it I'll send tomorrow a part of it since we have finished work for today.

The installation was done from source file: ftp://ftp.shrubbery.net/pub/tac_plus/tacacs+-F4.0.4.26.tar.gz

The problem disappears when I re-instal a fresh copy of OS, but after some days happens again.
If I re-install only the tacacs service the problem remains, does not disappear.

Do you mean after re-installing the O/S or just reinstalling tacacs?  What appears in the logs when it begins failing?

Can you install from sourcecode instead of the Centos package?

You have not attached the configuration & logs.
