AIX

Sir's, the problem is i have script and 1 user in different 30 servers that ssh to our main server at the same time. Then after that may account automatically locked. I dont know what is the reason, is it the max connection of 1 user using ssh.

Pls help. How to fix this.

I am not sure I follow exactly:

You have a script that ssh's to 30 other servers?
You have a script that ssh's from 30 other machines?

Your account is automatically 'locked'? What does this mean exactly, its not a normal error message someone is going to likely see for this type of activity.

From what I recall about programs like dssh (distributed secure shell, where you 'dssh web' and it will make a ssh connection to all your web family hosts, then if you type 'apachectl restart' it will issue the command on all the hosts and give you output / logging with a prefix of the host name) is that they handle this type of thing quite easily. I would look to the faq's of the dssh like applications, there are a few good ones out there.

If you gave us the os your using and more detail on this 'error' it would be helpful. My guess is that your hitting a ulimit or activating a ids/snort rule that some administrator that is ahead of you on this mischief.

Amen to what HPAVC said: troubleshooting systems one never has seen would be a lot easier if at least the problems arising would be described concisely.

A possible problem could be the "maxlogin" value of AIX. It limits the number of simultaneous non-root connections. The value can be found in /etc/security/login.defs, look for a line that looks "maxlogins = <nr>" in the "usw:" stanza.

You can change the value by issuing:

chlicense -I -u <number>

I hope this helps.

Thanks for insights sir's..i will rephrase my statement, i have 1 main server, and 30 sub server. In that 30 sub server i have 1 script each that ssh to my main server w/ the same USER and Password that they were using. After that it will locked that user. so my question why SSH locked my account or the system locked my account. How can i adjust max_user_connection? Or is that the problem? i dont know why it locked the account. Every morning i always unlocked the account. Please help

No clue without details on the OS and the exact error we are just guessing, I mean the tool that you "unlock" the account with should provide the exact answer it its man page "also see: ..." area on how to modify.

Also odd that it occurs after all 30 are done, rather than on the 24th login and then the last 6 fail or what not.

something like that, the scripts were meant for backup, they were some files that have been backup they are some not. Because lit was locked after some servers ssh to my main server. And every morning I reset the account. But the bad thing is they were files were'nt backup because the account has been locked.

I guess there's no problem w/ my aix 5.2, it only happens now, where a lot of servers using only 1 account.

Well open up the license and or auth logs and ...

$ ssh mainserver
$ ssh mainserver
...
$ ssh mainserver
$ ssh mainserver

in a loop in another tty and see exactly what is locking that account. It maybe be enough to just add it to a privileged group wheel, adm, backup or whatever the lockout does.

The error should exactly tell you what you need to start looking for man page wise.
