Before enabling ssh to use PAM authentication it is recommended that you leave an additional login window open with root access until you verify that ssh with PAM authentication is working properly. If PAM is not configured correctly you will not be able to log into the machine to correct the configuration problem until you boot the machine into maintenance mode and change /etc/security/login.cfg back to its original state.

(Sometimes the solution can be if group and other write permissions are removed.) /etc/ssh/sshd_config. If in sshd_config file. Permissions as in the original AIX). Hello, Can someone tell me, How i can enable PermitRootLogin in /etc/ssh/sshd_config in AIX currently the server cannot be su - root to as well.

1) Edit the /etc/pam.conf file # vi /etc/pam.conf Add the following sshd lines: # Authentication sshd auth required /usr/lib/security/pamaix # Account Management sshd account required /usr/lib/security/pamaix # Password Management sshd password required /usr/lib/security/pamaix # Session Management sshd session required /usr/lib/security/pamaix 2) Edit /etc/ssh/sshdconfig # vi /etc/ssh/sshdconfig Uncomment the UsePAM line and change UsePAM = no to UsePAM = yes. 3) Edit /etc/security/login.cfg # vi /etc/security/login.cfg Change this line from: authtype = STDAUTH Change to authtype = PAMAUTH Stop and restart sshd. # stopsrc -s sshd # startsrc -s sshd.

I am no longer successfully able to connect to my AIX LPAR. Ssh -v user@ OpenSSH6.2p2, OpenSSL 1.0.1c 10 May 2012 debug1: Reading configuration data /etc/sshconfig debug1: Connecting to port 22. Debug1: connect to address port 22: Connection refused ssh: connect to host port 22: Connection refused This was after attempting to make an sshdconfig update take effect (potentially incorrectly) by running stopsrc -s sshd startsrc -s sshd Prior to running the stop and start, I was able to connect, now it refuses as above. I still currently have one connection open, is there anything I can do to resolve/troubleshoot this? I've already looked at thread, but I am unable to figure out basic things like whether or not the SSH daemon is running (I don't think it is) or how to start it if it is not. Ps -ax did not recognize x as a flag. (edited based on comments) user1@:/usr/sbin ps -ef grep ssh root 5046410 1 0 09:37:38 - 0:00 sshd: user1 priv root 5374164 1 0 13:28:03 - 0:00 sshd: user1 priv user2 581204 0 16:25:39 - 0:00 sshd: user2@pts/0 user1 73212 0 09:37:40 - 0:00 sshd: user1@notty root 9175212 1 0 09:37:40 - 0:00 sshd: user1 priv user1 110410 2 09:37:40 - 0:01 sshd: user1@pts/1 root 11141204 1 0 16:25:33 - 0:00 sshd: user2 priv How can I connect to this LPAR again?

Any help is very much appreciated! After finding, I noticed that something similar is happening, but instead of a missing module, it was something with sshdconfig. Check status of the daemon: user1@:/usr/sbin lssrc -s sshd Subsystem Group PID Status sshd ssh inoperative Attempt to manually start (using absolute path): user1@:/usr/sbin /usr/sbin/sshd /etc/ssh/sshdconfig: line 1: Bad configuration option: penBSD: /etc/ssh/sshdconfig: terminating, 1 bad configuration options Turns out this file was incorrectly removed earlier (prior to sshd restart attempt), but new file was created to be an exact copy of another machine (or so we thought, it was actually a bad copy/paste job).

Based on the line 1 error, we updated: penBSD: sshdconfig,v 1.80 2008/07/02 02:24:18 djm Exp $ to: # $OpenBSD: sshdconfig,v 1.80 2008/07/02 02:24:18 djm Exp $ Not only can we now connect properly, the configuration change we were trying to make in the 1st place to enable X11 forwarding seems to have worked as well.
