Re: startup daemon as unpriviliged user
Bingo! Thanks a bunch! I'll check out gettytab too, but the @reboot is exactly what I needed for this. Lou On 02/13/04 08:04 PM, Craig Reyenga sat at the `puter and typed: man 5 crontab -- check out @reboot Or, for something crazy, man gettytab; you can autologin on a tty and then use a shell script to do all kinds of fun things. I used to run X without xdm that way.

For a user unpriviledged but with a login, run service as user if available as an option to the app you want to run or use sudo or equivalent (as root you can sudo anything as any user). I have made this little blurb for my desktop after realizing that it's easy to forget starting spambayes pop3 proxy and then have my kmail be not able to connect to localhost:10110: % cat /usr/local/etc/rc.d/zzz_local_users.sh #!/bin/sh # spambayes cd /home/danny sudo -u danny sb_server.py -D hammie.db -l 10110 pop.vuurwerk.nl 110 # get yahoo mail every n minutes sudo -u danny ./.fetchyahoo It's a bit crude (need to hit enter to get my console back) but for my desktop its ok as it is. Obviously sudo needs to be installed and in path. The processes show up if I 'ps' as user danny and I can kill or hup them.

It's reasonable to create a fetchmail.sh script in /usr/local/etc/rc.d which
does something like:
#!/bin/sh
USER = me
COMMAND = /usr/local/bin/fetchmail...
su - ${USER} -c ${COMMAND}
In this case, however, you might want to invoke it from a per-user cron script
eievery hour or so instead...
