Try this:

Router (config) # line vty 0 3
Router (config-line) # transport input ssh

Unfortunately not all cisco routers support SSH...

Enter configuration commands, one per line. End with CNTL/Z.
orion(config)#line vty 0 3
orion(config-line)#tr
orion(config-line)#transport in
orion(config-line)#transport input s
orion(config-line)#transport input s
orion(config-line)#transport input s
orion(config-line)#transport input ss
orion(config-line)#transport input ss
orion(config-line)#transport input ss
orion(config-line)#transport input ss
orion(config-line)#transport input ss
orion(config-line)#transport input ss
orion(config-line)#transport input ss?
% Unrecognized command

Seems mine doesn't recognize it...
Will upgrading the IOS fix this?

Yes, if you have enough flash and ram.

Perhaps, but my 806 also doesn't support SSH... It depends on the router.

They have changed the feature navigator interface yet again, but I
think about the minimum IOS you need for SSH on your 3640 would be
c3640-is56i-mz.12.15.T16 whis is the IP PLUS IPSEC 56 feature set and
wants a recommended minimum 48MB DRAM and 16MB flash.

That gets you SECURE SHELL SSH VERSION 1 SERVER SUPPORT with 56 bit
encryption. You can go up from there.

Hi,
I saw that this is a very old thread but just to help new visitors.
- Yes SSH support starts after some IOS versions
- Your IOS must be K9 (includes k9 in its name) it means with crypto. There are still some IOS images W/O CRYPTO because of export limitations to some countries.
- And you should make necessary configuration . You can find a sample at http://cisco-network.com/hands-on/ssh-cisco/
