Hi folks, I have setup a 2 crontabs jobs,

one it's a compiled C program that checks if the pop3 server responds, if  
so it's die,
if not it restart the pop3 server.

and the other it's the same but for smtp server.

the 2 programs work ok, but the do not execute from crontab when I logged  
out from console,ssh.
but when I logged on into an ssh session or console session then execute.

it this behavior right?

I'm using 4.3

4.3 has been out of support for almost 20 months.  You've apparently
chosen to continue using it instead of upgrading, so supporting it is
your problem.  Good luck!  I suggest you check the log file for cron
(read the cron(8) manpage for details).

...and yet you seem to have ignored my suggestion to read the cron
log.  Surprise: the same suggestion applies to 4.8!

So, read the logs, describe your setup more completely such as by
including a full dmesg.  Right now, we don't know what architecture
this is, whether virtualization is involved, what user are these
cronjobs set up as, how you confirmed that they are running when
you're logged in, nor how you confirmed that they are *not* running
when you are not logged in.

Without details, I don't see any way to help you other than guessing,
so here's my random guess: it's obviously a bug in your virtualization
setup.  (You didn't say it _isn't_ such a setup, so I could be right.)

no virtualization, i386, I already read the manpage of cron,
didn't say anithing that apply to this situation.

He said read cron logs, not man page...

Programs started by cron will have a different env(1) than those
started from interactive sessions; most notabily $PATH will be
different.

Is there any restriction on accesing networks sockets from cron?

[ message continues ]

There are no such restrictions that do not also restrict programs
started from the shell by/as the same user.

No, this is not normal behavior for cron on ANY flavor of UNIX.
Sounds like a good guess, Martin, but no one can know because he
still refuses to give any of the info he was asked for.
Any real info at all, actually.

Expecting any real info whatsoever on misc@ seems to be futile.
A guess is as much as they can or want to expect.
Perhaps it's some kind of recruitment scheme.
