How to scp as different user in perl script
Hi,

I am writing a perl script that needs to change to a another user and scp files to a remote server. The passwords should not be prompted but read from a config file.

Please help.

Thanks

How do you plan on encrypting the config file to prevent it from being read?
It seems to me that the wisest course of action might be:

First, create ssh keys to allow your host to ssh into the remote host
Code:
scp /source/dir/file user@hostname:</target/dir>
scp -r /source/dir user@hostname:<target/dir>

Thanks. The config file storing the password will have proper permission set to avoid any other user reading it.

My main problem is, I need to scp as another user. How do I switch user and pass the password in the program. It is always prompting me for the password.

Thanks

You may consider changing the UID of the person running the perl script. setuid or some such...

Visit CPAN's site and take a look at Net::SCP Net::SCP - Perl extension for secure copy protocol - search.cpan.org.

It's the right way to do this...

Also, I did a quick google search for "Sending Password with scp", and ran across this site: sshpasswords[modp.com]
Here's what it had to say:
Quote:
#!/usr/bin/env expect -f # -*-tcl-*-
set timeout -1 # wait until done

# trick to pass in command-line args to spawn
eval spawn scp $argv

expect "password: $"
send "password\n"

# wait for regular shell prompt before quitting
# probably a better way using 'wait'
expect "$ $"
