A Forum reader asked the following question:
"I want to know how many LDAP connections are active on a server. Is there a way to get that information? We are running eDirectory 8.7.3 on Windows 2000."
And here's the response from Novell's Aaron Burgemeister ...
It's simple enough to code. On *nix platforms it would look like this:
netstat -anp | grep "389\|636" | grep ESTABLISHED | wc -l
The above line says to show all connections numerically, looking for 389's or 636's. (Those are secure / insecure ports - that can be trimmed down to one port or another if you like.) In those ports, look for those connections that are established - the command gives you a count of lines (how many there are).
On Windows it's a similar process:
Take that output and look for lines with "389" and "ESTABLISHED" and then count the lines. This is simple enough in Perl, probably a one-line Perl script, if you install it from ActiveState or something similar.
Peter Kuo adds:
"Note that unless you have presistent connections, usually an LDAP 'connection' doesn't really exist - in the sense that the client authenticates, queries for the info, gets the data, and disconnects right away."
Akos Szechy adds:
"On Windows you can also use the same utilities, as there is a port for grep and wc at http://unxutils.sourceforge.net/ ... It works quite nicely."
