Cron job initiating ssh AND sudo (from user, not root)
I've been bashing my head on the desk for 2 days trying to get this to work, but I've had no luck. I'll try to be as clear as possible in my explanation without dragging out the details. I'm trying to set up a cron job for user "john" which runs a script. This script initiates an ssh connection to another box (user : john), and then does a series of commands which require privilege escalation. For the purpose of using keys and avoiding passwordless root traversal across ssh, I cannot do this with the root cron.
Example script and cron job.
example code from localscript.sh
Now I have added the entire path to all of the commands, and that fixed the rest of my script (which is actually quite extensive), but I simply cannot get cron to work with sudo on the remote machine. Now for the same thing you always hear...If I run this script manually, everything works great. When I run it as a cron job, it does everything fine EXCEPT the line with the sudo. Any help is very much appreciated.

I am running a few scripts through a cron job. This is for checking some key services that are running on by box. The problem is, everytime the cron runs, it sends a mail to the root account. The root account mails need to cleared every now and then. Is there some way I can stop these... (1 Reply)

Hi there,
I have an ESXi server and I need to shut it down every night (say at 11 for simplicity). To shut down the ESXi box remotely, I can send an SSH command "poweroff".
Basically my question is, is there any way that I can save the script on my DD-WRT router so that it will login to the... (3 Replies)

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for hostbased authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during hostbased authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the the global client configuration file /etc/ssh/ssh_config by setting
HostbasedAuthentication to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about hostbased authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if hostbased
authentication is used.

ssh-keysign first appeared in OpenBSD 3.2.
