Hi, I am having a strange problem, where I cannot get pam_access to work as intended. I have placed the following line in /etc/pam.d/system-auth account required /lib/security/pam_access.so Then, in /etc/security/access.conf, I have put the following line: -:mok:10.14.44.104 I.e. I should prevent myself from logging on from host 10.14.44.104. However, when I try to log on (using ssh) from the specified host, I get in without a problem. There is nothing in the logs. It does not help restarting sshd, or rebooting. It does not help putting "ALL" instead of the IP number. I happily get in... Another weird thing is that if I give the argument "debug" to pam_access.so -- as the manual says you can -- it does say something in the log, namely that "debug" is not a recognized option. The system is CentOS release 4.4. I hope someone on this list can offer a bit of advice! Cheers, Morten
