How to change default TCP (ssh) port number 22 in cucm 11.5

Hello all,

 

I am using CUCM 11.5 and I want to change the default SSH port from 22 to another number as all the other servers in our organization have different ssh port numbers for security reasons.

 

How can I change the default ssh port number in CUCM?

 

I am using ESXI 6.5, and UCOS 6.0

 

Thanks in advance.

AFAIK you cant change that. You need to use the port 22.

No, you cannot change it, CUCM uses a customized and closed OS and plenty of things you could do on a regular Linux server you cannot do here because there's no root access.

Usually, we can change the ssh port number in cisco routers and servers (linux, UNIX, windows etc..), likewise can we change in cucm?

 

I do not want to completely block ssh,

My task is to deny ssh access for cucm via port 22, instead, I would like to set a different port number for ssh and access it.

 

is there any other solution?
