Hi All,

I wrote a small crontab to send the output to a group of user every 5 minutes. See Below. Somehow, they (I am also part of that group) are not getting emails. Can anyone point me out on what i am missing 

#custom cron for running the netstat -n command
*/5 * * * * netstat -n | mail -s "output on netstat"

Can you please advise.

Thanks
Anubhav

Anubhav,

The cluster-wide crontab is in /etc/mcp/override/crontab.smbtime. Note that isi_ropc executes its argument on only one node.

Unfortunately Dell broke the `mail` command a while ago.

What version of OneFS? I don’t think it will send email. Try something like this instead:

*/5 * * * * “date; netstat -n; echo" >> /ifs/data/netstat

You could have an NFS client with /ifs/data/ mounted mail the file, if that’s what you really want.

I have just been using the /ifs/tools/sendml.py tool.
ex: /usr/bin/python /ifs/tools/sendml.py -t email address -s "Subject"

Nathaniel,

Does that work as any user or only root? I think someone suggested that in my (fruitless) search for a mail command.

Thanks,

Chris

I am not sure if it requires root- I don't have local users on the isi nodes... so that makes it harder to test and find out on my end...
quick glance- it has perms of root:wheel and 771, but unsure what the dependencies of it require in terms of permissions
