Admin account - intruder lock out

I just noticed that the Admin account is continuously locked out. When I look in Console1, it says the IP address of the intruder is the same address of the server. I uncheck intruder lock out and seconds later it's locked out again. It seems like something is trying to log in every 4 seconds using admin's account. Any suggestions on trying to find out what is causing this?

Thanks,
Mike

Find what is trying to login over and over again. An old service, for
example, could do this easily if you changed your password somewhere along
the way but didn't tell all of the services using the old password. The
key will be isolating the machine failing the logins over and over.

Good luck.

Re: Admin account - intruder lock out

As AB says. Most commonly a server-based app such as anti-virus or a backup utility.

That's just it, nothing has changed. Is there a way to see all of the processes that are running on a 6.5 box?

In that case use the same steps but find out who is attempting to login
over and over. Intruder detection is meant to detect intruders. Go and
find them whether it's a service, a human, or a script started by a human
to break in.

Good luck.

"modules" is the nearest equivalent to that idea.

Are you saying the Admin user's password hasn't been changed? If that's really so, I can only guess that whatever app is doing this has been configured with the wrong password for the Admin user.

Re: Admin account - intruder lock out

This is odd, I just had an issue with a users account that did this for about an hour. During that time period I had shut them down to see if the login attepts would stop but did not. In C1 I noticed that it was the server ip that the intruder was locked from. There is no cifs, afp running on any of my servers. This had never happened before. The only change made was I started running ACIPDRV on this box yesterday. No errors in dsrepair or sync issues.

Are there any nmas logs that can be looked at to see if there is an address involved? No IPX only IP here.

Also, updated sshd (should have no involvement) and iprint client to 5.60 last week(?).

Re: Admin account - intruder lock out

The best way (I use it all the time), if NetWare run pktscan.nlm and
take the output file and open it in Wireshark. In Wireshark, set the
filter to:

ldap.errorMessage == "NDS error: failed authentication (-669)"

....find the user you are interested in. The rest will avail itself from
there. Most likely it is an LDAP auth, is what I find. Either way you
will see the source address and a lot more.

Brief, 'cause I'm heading out the door, sorry.

Re: Admin account - intruder lock out

Thanks for the reply, turns out that one of our copiers that scans via ftp to the server had this users account as the login account. The user had changed their password a few weeks back. The copier had the old password and that's what was causing the intruder locks..... Knew it had to be something simple like that. :^)
