ASA5510 inb active/standby configuration. Somewhere along the line I've lost telnet when failed over to the secondary unit. The firewall passes traffic and I can manage it from ASDM. Nmap shows the primary listening on port 23 but not the secondary when it has the active role. Can't think of any recent changes to the 2 interfaces configured for telnet. I did change the speed of the outside interface to auto to match the ethernet port, but telnet was not bound to e0/0 anyway. I suppose I could rebuild failover from scratch .....
No can do. The secondary unit isn't listening on port 23, there aren't any log entries. As a matter of fact, I can't find any log entries for telnet on the primary unit. Let me look into that some more.
