Top Forums UNIX for Dummies Questions & Answers If user has own crontab, results in accumulation of root CRON processes Post 302392977 by Narnie on Saturday 6th of February 2010 06:59:15 PM

According to the info I read, ubuntu is set up for running cron at log level 1, which will send an email that the process was run or when there is an error.

I have run it on another computer without any problems, too.

I'm running 9.10

I have deleted the mailx program to see if it is hanging on the sendmail.
It tries to send the mail, but then there is no process and it seems to hang there.

This is a ps auxf with bsd-mailx (which depends postfix):

Code:
root     14693  0.0  0.0  91236  1660 ?        S    Feb05   0:00  \_ CRON
root     14694  0.0  0.0  91244  1160 ?        S    Feb05   0:00  |   \_ CRON
woodnt   14696  0.0  0.0  50152  2800 ?        S    Feb05   0:00  |       \_ /usr/sbin/sendmail -i -FCronDaemon -oem woodnt

This is with mailx/postfix unintalled:

Code:
root     31543  0.0  0.0  91236  2196 ?        S    17:47   0:00  \_ CRON
root     31544  0.0  0.0  91240  1272 ?        S    17:47   0:00      \_ CRON
woodnt   31545  0.0  0.0      0     0 ?        Zs   17:47   0:00          \_

Hence my belief that it has to do with mailing and cron jobs.

I've tried to run this in a terminal:

Code:
/usr/sbin/sendmail -i -Fwoodnt -oem woodnt

but never got a prompt back without Ctrl-C

Any other ideas from anyone?

irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
