How cacti runs scrit.pl on a remote host ?

[dry]

Hello,

sorry formy bad english ..

I would like to know what mecanism cacti uses to execute script.pl (like linux_memory.pl) on the managed host, whereas the script is located on the manager host ?
Need the managed host to have a web server running with php installed ? or any other thing ?

could U explain me ?

I hope u ll be able to understood my question

Thx, Dry

Typically for remote hosts, you would use SNMP.

The scripts that are tied to localhost are really only designed for localhost.

But with some ssh/rsh magic, you could execute those scripts on a remote server.

Hi rony,

I assume you mean using public key/private key pairs you could do it. Do you happen to have any examples of how this would be done? I guess you would add a data input method that worked that way.

Have you heard of anyone doing it? I'm curious to try it, so if I do get it working I'll post it here. Maybe it can be added as part of the Cacti Documentation.

-P

if you have ssh keys setup correctly and running something like Keychain
( http://www.gentoo.org/proj/en/keychain/ )
to keep your passphrase in the memory you can do something like this

ssh hostname <remote comand and its arguments>
it will login into the remote server, run that command and disconnect

for example i want to run `du -sh /www` on the remote server

Code: Select all

aragorn::~% ssh 192.168.1.3 du -sh /www
18G     /www
aragorn::~%
