I compiled OpenSSH_6.6p1 on one of our server. I am able login via SSH to the upgraded server. But I am not able to connect to other servers running OpenSSH_6.6p1 or OpenSSH_5.8 from this. While connecting I am getting an error as below.
Read from socket failed: Connection reset by peer
On the destination server in the logs, I am seeing it as below.
sshd: fatal: Read from socket failed: Connection reset by peer [preauth]
I tried specifying the cipher_spec [ ssh -c aes128-ctr destination-server ] as mentioned in ssh 'connection reset by peer' problem since 5.8p1 (archived version) and was able to connect. How can configure ssh to use the cipher by default? Why is the cipher required here?
telnet ip.or.name.of.offending.server 22?
