Centos 7 SSH authentication with Cisco ACS TACACS

Post by TheChieftain » 2018/12/03 15:26:41

Hi all,

Has anyone tried to authenticate users on a Centos 7 host, with TACACS against Cisco ACS ?
I added the Centos 7 host to ACS and I know the host is able to reach ACS.
I opened TCP port 49 on firewalld.

and followed the below steps:
https://askubuntu.com/questions/217649/ ... ver/589388

During an authentication attempt, I don't see anything in the ACS logs, and doing a tcpdump (on the centos host) in the same time, I see that actually no requests are being sent to the TACACS server.
What am I missing ?

Thanks,
N

You almost certainly don't need to open that port in firewalld. That is for inbound connections. Outbound connections automatically have responses allowed.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
