The minimum firewall ports for a Windows domain controller and linux server
Posted in Operating Systems, Windows, Network, Firewall, Tips on Friday, February 16, 2018 by cam
In order for a Linux (client) box to communicate with (and perform NTLM auth) a Windows domain controller through a restrictive firewall you would need the following ports opened at a minimum:
udp 53 tcp/udp 88 tcp/udp 135 tcp 139 tcp 389 tcp 445 tcp/udp 464
sshd without-password vs prohibit-password
Upgrading a server from Debian 8 to Debian 9 - I noticed in /etc/ssh/sshd_config that ‘PermitRootLogin’ had the argument ‘prohibit-password’. Having not seen that before I wondered what the difference was between that and ‘without-password’.
Turns out that mean and do the same thing - but ‘prohibit-password’ was introduced to be less ambigous. So there you have it!
Check out the release notes here for proof :-)
