CAPSMAN info dump

I was asked by a friend to give a quick rundown on Mikrotik CAPSMAN configuration, so I dumped the config and added some notes. :) Packages I’m currently running v6.38 but was running about v6.2 only a week or so ago - make sure you have the “wireless” package enabled. Older RouterOS versions required the capsman-v2 package, which is now deprecated. > /sys package print Flags: X - disabled # NAME VERSION 0 routeros-mipsbe 6.38 1 system 6.38 2 ipv6 6.38 3 wireless 6.38 If there was an X, enable it (in this example /sys package enable 3) - remember you’ll need to reboot after enabling a package.

Domain LDAP listening check

A quick command for checking if your Active Directory servers are all listening on LDAP. Guess who had an issue with that today? :) dig +short domainname.internal | xargs -I{} /usr/sbin/hping3 -p 389 -q -c 1 {} 2>&1 | egrep "(transmitted|hping)" You’ll need hping3 - it’s installable from apt-get on Debian, can’t comment about any other distributions. A quick explanation for each part: dig +short domainname.internal - pull the IPs of the hosts in the domain entry - they’ll be your domain controllers sudo is required because hping uses raw sockets xargs runs the next command on each input line hping3 -p 389 - connect on TCP to the LDAP port 2>&1 - redirect STDERR to STDOUT to make it more easily filtered egrep - filter only the required lines This’ll hit each server once and show an output like: --- 1.2.2.2 hping statistic --- 1 packets transmitted, 0 packets received, 100% packet loss It is dirty, but it works!
