Full Discussion: Run shell script as different user
Top Forums UNIX for Advanced & Expert Users Run shell script as different user Post 69898 by mskarica on Thursday 21st of April 2005 11:23:36 AM

Ok, I think I should rephrase my question. I did some more research on daemons, and I think I can ask my question better now.

A daemon is a process that runs in the background (like a fork), whithout user interaction (from what I read). So basically what happens is that when an email is received, and the shell script is invoked, a daemon is running the entire process. I need to find a way where I can make the daemon act as if it were a unix user so that the process is run as if the user is the one who is invoking the scripts that are called in the main script, rather than the daemon.

So my basic idea is: email is received, forwarded to a script (daemon is still the owner at the moment), in the main script first thing I want to do is change the user from the deamon to another valid unix account, so then everything that is performed from there on out is performed as if the unix user that I specify is the one who invoked everything.

Does that make more sense? Any ideas?

Thanks

sndrd

sndrd(1M)						  System Administration Commands						 sndrd(1M)

NAME

       sndrd - Remote Mirror daemon

SYNOPSIS

       /usr/lib/sndrd [-c max_connections] [-l listen_backlog]

DESCRIPTION

       The  sndrd daemon processes client Remote Mirror requests. Only the root user or a user with equivalent privileges can run this daemon. The
       daemon is automatically invoked in run level 2. sndrd restarts the TCP transport layers.

       Administrators wanting to change startup parameters for sndrd should, as root or equivalent, make changes  in  the  /etc/default/sndr  file
       rather than editing the /lib/svc/method/svc-rdcsyncd file. See sndr(4).

OPTIONS

       The sndrd daemon supports the following options:

       -c max_connections

	   Sets the maximum number of connections allowed to the server over connection-oriented transports. By default, the number of connections
	   is 16.

       -l listen_backlog

	   Sets connection queue length for the RDC TCP over a connection-oriented transport. The default value is 10 entries.

EXIT STATUS

       0	    Daemon started successfully.

       >0	    Daemon failed to start.

       Error information is reported to syslog at level LOG_ERR.

FILES

       /lib/svc/method/svc-rdcsyncd

	   Shell script for starting sndrd.

       /lib/svc/method/svc-rdc

	   Shell script for stopping sndrd.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWrdcr, SUNWrdcu	   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Evolving			   |
       +-----------------------------+-----------------------------+

       svcadm(1M), syslogd(1M), ds.log(4), attributes(5)

NOTES

       Do not manually stop the sndrd deamon. If you need to manually stop sndrd perform these steps. This stops both the sndrd and sndrsyncd dae-
       mons.

	 # svcadm disable svc:/system/nws_rdc

	 # svcadm disable svc:/system/nws_rdcsyncd

       Do  not manually start or restart the sndrd deamon. If you need to manually start sndrd perform these steps. This starts both the sndrd and
       sndrsyncd daemons.

	 # svcadm enable svc:/system/nws_rdc

	 # svcadm enable svc:/system/nws_rdcsyncd

       See svcadm(1M) for additional information.
