Using Net::SSH to contact Cisco Routers 1

[netman4u]

Anyone have any sample code for using Net:SSH to connect to and run a sho command?

Net:SSH does not seem to have a way to pass a password to log in and expects a certificate. On my test router I SSH to it and it asks me for a username and password so I do not think Net:SSH will work. I also cannot use Net:SSH:erl as I am using a windows system.

Anyone have any command line examples that work? I dug this up on this forum:

my $password = 'password';
my $user = 'user_a';
my $ip = '100.100.201.22';
my $results=`"(echo $password) | ssh $user@$ip"`;

But it does not work I am still prompted for a password.

Any ideas?

Thanks,

Nick

What makes you think Net::SSH:erl won't work under windows?

Thanks for the reply Paul. I am testing on windows using Active State Perl. My program will eventually run on a Solaris 9 system. I know the Net::SSH:erl will probably do the job as it allows a password however it requires the installation of a large quantity of Crypt modules as well as the Math:ari program and other libraries.

Suffice it to say that I tried going that route in my dev environment but could not get the Math:ari compiled. My Solaris systems have no access to the internet to allow the use of MCPAN and I am not allowed to install any libraries on the systems and it takes weeks if your lucky here to get the unix admins to install them.


That being said, can anyone help me with SSH to cisco devices that require password authentication?

try using PuTTy to cache the cert of the router?

it's good for replacing windows also ;-)

I have been told that the cert will be cached on my Solaris system. What we have here is a lack of understanding on my part of how Cisco SSH works. I did not know that Cisco had a way of implementing certifications as I was prompted for a password when "SSHing" to the routers. If I had the proper cert I would not have to.

My apologies.
