Hello list, I took another stab at finding a way to add a sudo user remotely and it gets you most of the way there. If you execute the script as root it works beautifully and does just what you want. Which is add the user to the group and gives that user group rights to certain commands.
But if you execute it as a user who only has sudo access to the /etc/sudoers file it errors out. cloud:~] bluethundr% ./add_sudo.sh reverse mapping checking getaddrinfo for $host failed - POSSIBLE BREAK-IN ATTEMPT! [sudo] password for bluethundr: Sorry, try again. [sudo] password for bluethundr: Sorry, try again. [sudo] password for bluethundr: Sorry, try again. sudo: 3 incorrect password attempts Connection to $host closed. 1 reverse mapping checking getaddrinfo for $host failed - POSSIBLE BREAK-IN ATTEMPT! bash: /tmp/sudoers.tmp: Permission denied Connection $host to closed. 1 The main problem is that the script doesn't enter the password. I'm attempting to echo the user's sudo pass in like this: $SSH -t $USER@$HOST <http://host.jokefire.com/> 'echo $PASSWD | $SUDO -S $CP /etc/sudoers /tmp/sudoers-template' (of course I'm trying it out in my own environment before I try to use it in their environment). Here' s the script itself, I was hoping you could offer some help here: #!/bin/bash SSH='/usr/bin/ssh' ECHO='/bin/echo' TEE='/usr/bin/tee' SUDO='/usr/bin/sudo' VISUDO='/usr/sbin/visudo' CP='/bin/cp' CAT='/bin/cat' USER='user' HOST='beta' PASSWD='secret' $SSH -t $USER@$HOST <http://host.jokefire.com/> 'echo $PASSWD | $SUDO -S $CP /etc/sudoers /tmp/sudoers-template' echo $? if [ $? -eq 0 ]; then $SSH -t $USER@$HOST <http://host.jokefire.com/> 'echo $PASSWD | $SUDO -S echo "%my_group ALL=(root) NOPASSWD: /sbin/service, /bin/rm, /usr/bin/du, /bin/df" > /tmp/sudoers.tmp' echo $? if [ $? -eq 0 ]; then $SSH -t $USER@$HOST <http://host.jokefire.com/> "echo $PASSWD | $SUDO -S $CAT /tmp/sudoers.tmp | $TEE -a /tmp/sudoers-template" echo $? if [ $? -eq 0 ]; then $SSH $USER@$HOST <http://host.jokefire.com/> "$VISUDO -cf '/tmp/sudoers-template' 2>&1 >& /dev/null" echo $? if [ $? -eq 0 ]; then $SSH -t $USER@$HOST <http://host.jokefire.com/> "echo $PASSWD | $SUDO -S $CP '/etc/$SUDOers' '/tmp/sudoers.bak'" echo $? if [ $? -eq 0 ]; then $SSH -t $USER@$HOST <http://host.jokefire.com/> "echo $PASSWD | $SUDO -S $CP '/tmp/$SUDOers-template' '/etc/sudoers'" echo $? if [ $? -eq 0 ]; then $SSH -t $USER@$HOST <http://host.jokefire.com/> "echo $PASSWD | $SUDO -S $VISUDO -cf '/etc/sudoers'" fi if [ $? -eq 0 ]; then $ECHO -e "You have successfully added the user to sudoers" fi fi fi fi fi fi Thanks! -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
