Ellzey Thomas<br><br>So there is some level of support. I could not find out how to set the<br>facility and priority, so I just let tac_plus write to the file (I wanted<br>a<br>local copy anyway) and configured syslog-ng to read it and send the logs<br>
onto<br>my syslogger:<br><br># Tacacs accounting logs<br>source s_tac_plus_acc {<br> file("/var/log/tacacs/accounting",<br> default-facility(local6),<br> default-priority(info));<br>};<br># Remote logging to syslogger<br>
destination syslogger {<br> tcp("xxx.xxx.xxx.xxx" port(514));<br>};<br>log { source(s_tac_plus_acc); destination(syslogger); };<br><br>Not the most elegant solution, it does require you to keep your wits about<br>
you<br>if you change log filenames, but it does work. It's for syslog-ng, AFAIR<br>syslogd can be brutally assaulted into doing much the same,<br><br>> Lastly, is there a way to disable an account after X number of failed<br>
