BIGIP SSH Proxy Not working properly
Hi All,
Client system --------> BIGIP (SSH Proxy) ---------> Backend Server (key1) (Key2) (public key1 , Public Key2) (192.168.40.56) (Vip:192.168.42.152, self:192.168.41.153) (ip:10.10.100.189)
In my case Key1 and key2 are same. My SSH connection is happening perfectly fine without ssh profile attached.
Please find the below screen shot for the configuration of ssh profile.
Now I verified the public key in authorized_keys and it is there. Direct client to backend i am able to do the password-less conection.
But when i try it from BIGIP VIP it is not connecting at all.
I see the logs like below: F5: logs err : SSHPLUGIN: sshplugin_0|SSHPlugin|ssh_setup_serverside|Core|the backend ssh server does not have a public key that matches the configuration! (0) Erroring out of this connection.
Backend Logs : puppetmaster sshd[2748]: Set /proc/self/oom_score_adj to 0 puppetmaster sshd[2748]: Connection from 192.168.41.253 port 51484 puppetmaster sshd[2749]: fatal: Read from socket failed: Connection reset by peer
I took the packet capture and i can see the Reset is initiated by BIGIP.
I followed the same process given in [URL] from F5 site .
Now i need to troubleshoot what is causing my connection reset. Please help me with the solution how i can get it up an running.
And just out of curiosity why are we running continuous port 22 scanning for the backend server.
Logs: Mar 8 16:51:41 puppetmaster sshd[2747]: Set /proc/self/oom_score_adj to 0 Mar 8 16:51:41 puppetmaster sshd[2747]: Connection from 192.168.41.253 port 48174 Mar 8 16:51:41 puppetmaster sshd[2747]: Did not receive identification string from 192.168.41.253
Any help would be appreciated.
