SFTP Client service information

Hi,

How to find out which sftp client is installed in my system?
And the UserId and Password used for SFTP service.

I am using SunOS 5.8

Please help.

Thanks,
Raj

type "which sftp"

if that does not find it then

"find / -name sftp -type f"

then run it with something like "--version" or similar.
