Cannot enable ssh in Cisco IOS 12.3 1

[wstran]

Greetings,

I tried to enable ssh on my router that run 12.3 but could not. I think the version 12.3 supports ssh as I read the books or Cisco web site. Please tell me why. thanks!

For more information, the following are the only options that I got from my router:

Router(config-line)# transport input ?
all All protocols
lapb-ta LAPB Terminal Adapter
none No protocols
pad X.3. PAD
rlogin Unix rlogin protocol
telnet TCP/IP Telnet protocol
v120 Async over ISDN

Not all feature sets of 12.3 IOS support SSH. If you download a feature set with encryption or firewall capabilities you'll get SSH support.
