SCO SYSV on a HP server. Install notes

Phone extension that rings multiple external numbers (CCME Asterisk)

Skip to end of metadata

o to start of metadata

In this example we want to ring all the external numbers of a few people only by dialing extension 3331.

1: Connect to CCME and create a new dial-peer:

dial-peer voice 3331 voip
 description External Emergency Responders
 destination-pattern 3331$
 session protocol sipv2
 session target ipv4:192.168.0.XXX #(the Asterisk box)
 dtmf-relay rtp-nte cisco-rtp
 codec g711ulaw
 no vad

2: Connect to the asterisk server and add the extension in the default [incoming_context] in /etc/asterisk/extensions.conf: (192.168.0.YYY is the outgoing trunk)

exten => 3331,1,Dial(SIP/5145555555@192.168.0.YYY&SIP/51455555519@192.168.0.YYY&SIP/5145555552@192.168.0.YYY&SIP/5145555553@192.168.0.YYY&SIP/5145555554@192.168.0.YYY&SIP/5145555555@192.168.0.YYY)
exten => 3331,n,Hangup

3: Reload asterisk config and test the extension 

Limit number of unix logins

cat .profile

#!/bin/sh
limit=3

session=`ps -ef | grep '\-sh' | grep $USER | grep -v grep`

number=`echo $session | wc -l`

if [ $number -ge $limit ]; then
echo "No more logins / Il n'y a plus de login. You are already logged as:
$session "

sleep 5
exit 0
fi

# to timeout after 15min of inactivity and forbid users to change the tmout:
echo "TMOUT=900
readonly TMOUT
export TMOUT" > /etc/profile.d/tmout.sh && chmox +x /etc/profile.d/tmout.sh

Forward all emails from one sendmail to another

- in sendmail.cf change Djdomain.tld to something like Dj_subdomain.domain.tld Do the same thing for DMdomain.tld
- in the same sendmail.cf look for Fw or Fw-o and check the file it refers to (usually /usr/lib/mail/local-host-names); in that file remove the line stating "domain.tld" (in fact, remove everything, leave just _subdomain.domain.tld there), that way sendmail will know that it is not the default destination for the @domain.tld

- if necessary, create /home/$username/.forward (chmod 600, chown $username:$group) and put the right info in it

Dell Latitude Keyboard light

The backlit keys interface seems to be broken, so you need to mask the controlling service: systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service
then go to BIOS and and change the keyboard led timeout from 10s to 5s for AC Power and Battery mode - "For some reason if the kbd_backlight service is not masked, it somehow forces the bios led timeout back to 10s, and then the keyboard led always remains lit."
