Novell Cool Solutions: Tip

Posted: 4 Jan 2005

A reader recently asked: "How do you quickly find a user based on an IP address, without going through each user in ConsoleOne?"

Here are four solutions from various Forum experts, as well as some tips on login scripts that access IP addresses:

Solution #1: Use iMonitor

For a quick-and-dirty approach to finding users by IP address, just use Monitor. Scroll down to the user in question and look at the details.

Solution #2: Use NLIST

Use the following NLIST command:

NLIST /R /S > address.txt

This will dump user and Network Address stuff into a file then just open in notepad and search for the address, plus gives you a list for historical reasons. Here's a sample of what you might get:

Object Class: User
Current context: OU.O

User: testID
         Network Address:
                 TCP/IP Network Address
                 IP Address:
         Network Address:
                 IPX/SPX Network Address
                 Network: 18
                 Node: A0C01596DA
                 Socket: 4088

Solution #3: Use JRB Utilities

Check out The JRB Utilities tool set is very handy to own. I use the GETREST.EXE command-line utility as follows:

Getrest * na /j /n /r /x /y=u /e=none /l=address.txt

The output in address.txt file will be similar to this:

testID.OU.OU       0000001b:00012345678c:4d98

Then you just open the file in Notepad and search for the address. It also gives you a list for historical purposes.

Solution #4: Old School, from School Cool

This next solution if from the Novell forum ( As they say it, this is some "Old School" stuff!

"If I want to to write a login scripts for logging the date, time, username, ipaddress to a log files at server, is it possible?"

Here is one way to do it. In the login script, set DOS variables for whatever values you want to keep. For example:

       DOS SET User=%CN
       DOS SET LoginTime=%Last_Login
       DOS SET Address=%Network_Address

Then call a batch file from the login script as follows:

#cmd /c \\sys\etc\dothis.bat

Where the batch file contains something like this:

Echo %Login_Time% %Address% %User% >> \\sys\etc\Logfile.txt

The double ">>" will append the string to the file, and it will create a file if there is not one. This would also build a historical file on the fly.
