We were using AIX 5.3 on Power Servers. Now we installed few machines with AIX 7.1. On which we are facing that most of the ssh client (like RHEL 5 ssh client, secure shell client) are unable to login to AIX 7.1 box via ssh whereas putty client is able to login on same AIX 7.1 hosts.
Below is the debuging log from a RHEL 5 client ssh machine to AIX 7.1 server.
We have experienced the same problem. After much research it appears the cypher length is too big which causes the connection to die before proceeding further. You can test this theory by executing the following:
ssh -c aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128, <HOSTNAME>
To permanently resolve, you should update the version of openssh client on your Linux host.
I forgot to update on this forum. I was able to resolve the problem after changing the cipher in client list.By default client was using archfour , after changing it to some other like blowfish etc now client are able to connect quite nicely. It seem that in AIX 7.1 they have tighten the rope towards security and weakness.
