SSH on PIX firewall

If you are using PIX 6.3, then see:

generate) save all)

Configuring PIX to Accept SSH Connections Our first task is to generate an RSA public/private key pair to use t securely transfer the session key from the server to the client. Th hostname and domain-name must be set before the PIX will allow you t generate the key pair.

Assign a hostname and domain name to the PIX. This is required t generate the RSA key set.

pixfirewall(config)# hostname percival percival(config)# domain-name cisco.com

Generate an RSA Key pair and save the keys to Flash memory.

percival(config)# ca generate rsa key 2048

For >= 1024, key generation could take up to several minutes. Please wait.......... View your newly created RSA Public Key.

percival(config)# sh ca mypubkey rsa

After generating the keys, you must save them to Flash. Failure t perform this step will result in the erasure of the keys at the nex reload.

percival(config)# ca save all

Specify what hosts are allowed to SSH to the PIX and set the SS inactivity timeout. In this case, you will limit SSH access to a singl inside host and kill sessions after one hour of inactivity.

percival(config)# ssh 192.168.111.7 255.255.255.255 inside percival(config)# ssh timeout 60

Set the enable password and Telnet password. You will be required t enter the Telnet password to authenticate your SSH session.

percival(config)# enable password hArd2Gue$$ percival(config)# passwd Ace$$D3n13dNote

If you have previously configured a telnet password and enabl password, you don't need to change them for SSH to work.
