Hi, We all know that the PAM has been embedded on the current RedHat9, but it seems that it does not take effects. I just want to test the pam_limits.so, and I write a simple configuration to limit the number of process in /etc/security/access.conf as follows: myaccount hard nproc 5 (I want to limit the "myaccount" with maxnproc of 5 ) Then, I changed my root account to myaccount, and run ps and grep. [root@Redhat9 security]# su myaccount [myaccount@Redhat9 security]$ ps auxww | grep ^myaccount myaccount 1626 0.0 0.5 2368 1324 pts/2 S 14:36 0:00 bash myaccount 1627 0.0 0.5 2468 3324 pts/2 S 14:36 0:00 ps auxww myaccount 1636 0.0 0.5 1968 1329 pts/2 S 14:36 0:00 grep ^myaccount It means that I have run three processes. And now if I continue to run 2 processes, the myaccount should be prohibited by PAM. However, the PAM does not take effects to limit the myaccount. What is wrong with it? Are there something wrong with my configuration? [myaccount@Redhat9 security]$ man perl .... (it run ok, not be prohibited) Thank you very much~ - johson _______________________________________________ Pam-list mailing list Pam-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/pam-list
