Was this in the man pages...if so sorry for wasting your time, I was reading about the kill command and I don't have a unix box at my job to use the man command but wanted the answer now, and this site usually gets the answers to my simple questions quickly. Thanks for the info.
I'm curious. I was under the impression that it was simply a certain type of kill signal, in this case on a "hang up", or disconnection by the user running the process. I know certain processes restart on a HUP signal, but is that always the case, or is that simply how they handle that signal in a specific instance? For example , if I killall -HUP inetd, I know it will restart the inted daemon, re-reading all config files. But when I killall -HUP pppd, it literally hangs up...
Well, that was only an example. Regardless, will signal 1 (HUP) always cause a process to restart, or only in some cases? I was under the impression that it killed your processes when you logged out, thus the "nohup" utility for keeping your jobs running upon logout.
For example, if I telnet to nether.net, sign in, and run "mail", it tracks my processes. Say my session is dropped, or I close my session from my end. Isn't the HUP signal sent to "mail" to kill it, as opposed to TERM(15), or INT(2)?
I know that to restart, say, inetd, for example I can kill -1 it, but not all programs follow this convention. Is that correct?
I'm trying to provide "/usr/bin/kill -HUP" command to one of the user using sudo file. I have configured sudo as following:
Cmnd_Alias KILL1=/usr/bin/kill -HUPAA ALL=NOPASSWD:KILL1
When I login as the user and execute 'sudo -l' command, it... (2 Replies)

I modified /etc/syslog.conf and execute kill -HUP syslogd_PID. There's nothing changes on the PID when I did ps -ef|grep syslogd. It's the same. Do you think it restarted the process of syslogd?
Thanks in advance. (3 Replies)
