Hi , I am trying to do a "su -" in a remote machine and run some commands as root.
With the below script i am able to login to the remote machine, but i get "su: incorrect password" error even when the password is correct, i guess i am not passing the password in the correct format.
Please look at the below code and let me know where i am going wrong Thanks.
Code :
#! /usr/bin/perl
use Net::SSH::Expect;
#Preparing for ssh session
my $ssh = Net::SSH::Expect->new (
host=>"posideon",
user=>'testusr',
timeout=>10,
raw_pty=>1,
password=>'wel123go',
log_file=>"/forum/log.txt"
);
#Logging in to the session
$ssh->login();
print "Logged in \n";
# Commands executed on the remote machine
$ssh->exec("stty raw -echo");
$whoami=$ssh->exec("whoami");
print "\$whoami : ",$whoami,"\n";
$ssh->send("su -");
$ssh->waitfor('Password:\s*\z', 1) or die "prompt 'Password' not found after 1 second";
my $pass = "passw0rd";
$result = $ssh->send($pass);
print "\$result : ",$result,"\n";
$whoami=$ssh->exec("whoami");
print "\$whoami : ",$whoami,"\n";
#closing the session
$ssh->close();
Content of the log file :
Password:

Nice post about root using ssh::expect. I like your blog very much because it has very interesting articles of different topics like testking 642-067, testking 642-072 and testking 642-357 and their tips and tricks. I am a very big googler and search on different topics. Between searching i found your nice blog. Thanks for your this great blog.
