[Openswan Users] xl2tpd vpn logging

[Oguz Yilmaz]

I have problems with logging with openswan-xl2tpd.

I was able to get only the logs below:

Apr 17 09:13:49 2010 xl2tpd[21017]: Connection established to
12.34.56.78, 1701.  Local: 15025, Remote: 2 (ref=0/0).  LNS session is

Apr 17 09:13:53 2010 pppd[21273]: remote IP address 10.11.10.10


I have enabled log options in /etc/pp/options.xl2tpd
logfd 2
logfile /var/log/l2tpd.log

Now I have more logs in /var/log/l2tpd.log. However, No Time and Date
is printed.

My question is, How can I get user name, login time, logout time, L2tp
IP in a log file.

xl2tpd is xl2tpd-1.1.12

Best Regards,
