I am facing the following situation:
The root account on the RH linux box is frozen. But I can still install webmin rpm using another account. I do not want to thaw the root account permanently (though I can do it temporarily). Is there a way to add users to webmin from the command line and configure the modules that they can access (remember I need this to be done from the command line).
Any help will be appreciated.
You could script the process or do the lines manually, I suppose. You'll need to edit the following file to create users (and their passwords) for webmin alone. I still believe you may need root access, although you can create a webmin user to do these things with root priviledges.
# Creates Webmin user and junk password
cp /etc/webmin/miniserv.users /etc/webmin/miniserv.users.bak
echo "$USERNAME:$1$11111111111111111110:0:::" >> /etc/webmin/miniserv.users
# Changes Webmin user password from junk to what they reall want, then shadows it
/usr/libexec/webmin/changepass.pl /etc/webmin $USERNAME $PASSWORD
Something like this could do it, however it is not encrypting the password. It is making a junk password and then using the webmin changepass perl script to overwrite the junk w/ the true password. You could always throw in a crypto section ahead of that to encrypt the password prior to writing it to miniserver.users ($PASSWORD = the password you want, $CRYPT_PASSWORD *obviously* is the encrypted version):
# Encrypt our users password
# Get the encrypted version back from file
exec 6<&0 # Save stdin
exec < holdingfile.dat
echo "Encrypted pass: $CRYPT_PASSWORD"
echo "PASSWORD: $PASSWORD"
exec 0<&6 6<&- # Restore stdin
As far as the modules and all of that, that all deals with the webmin.cats, webmin.acl and adding the customized commands to the cloned module like:
#copy cp template - libexec part
ln -s $MODULEMASTER $USERNAME
# add new clan server to webmin.cats
cp -f webmin.cats webmin.cats.bak
echo "$USERNAME"=servers >> /etc/webmin/webmin.cats
# add new clan to webmin.acl
cp -f webmin.acl webmin.acl.bak
rm -f webmin.acl
cat /etc/webmin/webmin.acl.bak | sed "s/root:/root: "$USERNAME" /" > /etc/webmin/webmin.acl
echo "$USERNAME": "$USERNAME" $MODULENAME >> /etc/webmin/webmin.acl
# copy hd template in webmin directory
cp -rf $MODULENAME $USERNAME
# copy client's customized module acl
cp /usr/local/.../$MODULE.acl /etc/webmin/$MODULENAME/$USERNAME.acl
# add clone to new server directory
echo desc="$USERNAME" blahblah Control Panel >> /etc/webmin/$USERNAME/clone
