Hi this is the step to SSH:

1. Generate RSA key,

> ca generate rsa key

you can use 512,1024,2048 (2048 preferred)

2. Now you'll need to save using:

> ca save all

3. You'll need to configure ssh access on the PIX, so do the following:

> ssh 255.255.255.255 outside

OR

> ssh 0.0.0.0 0.0.0.0 outside - With this you can connect from any public address.

4. You can view you generated public key on the PIX by issuing:

> sho ca mypubkey rsa

According for your helpful instance.But I still can not telnet to pix from the outside interface.My configuration procedure as shown:

pixfirewall# config t

pixfirewall(config)# ca generate rsa key 512

Please use domain-name to configure Domain name first.

pixfirewall(config)# domain-name pix.com

pixfirewall(config)# ca generate rsa key 512

% Key pair was generated at: 01:36:51 UTC Apr 3 2004

Key name: pixfirewall.cisco.com

Usage: General Purpose Key

Key Data:

Remove all keys from the key ring ? [yes]

Keypair generation process begin.

.Success.

pixfirewall(config)# ca save all

pixfirewall(config)#

pixfirewall(config)# ssh 0.0.0.0 0.0.0.0 outside

pixfirewall(config)#

pixfirewall# show run

Any other wrong with my configuration?

Thanks a lot !

Hi,

Looks fine with the config. Have you try to used "putty" (telnet program for ssh-can be search at google). Try to ssh from putty.

you can not telnet to PIX(outside)

you need use ssh, or you may establish vpn connection to PIX and when use telnet.

Hi,

I usually configure the PIX for CVPN Client access, then allow addresses from the dialup pool to telnet from the inside

telnet X.X.X.X 255.255.255.255 inside

Then add

manaegement-access inside

You can then establish a VPN from a client and then telnet to the inside address

This is probably old news but it might help
