Bug 48069 – UML init start script, to automatically start and stop UMLs, with ssh dummy user

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Thomas Lassmann 2004-04-16 14:13:44 UTC]

I did write a little init script for gentoo. Works great. There I can startand stop my UMLs with init. To stop the UMLs I need a gohst user, this user can shutdown the UML over ssh without a password. 

Hope this is the right repository. Hope this helps.

Reproducible: Always

starts and stops one UML

[Comment 3 Thomas Lassmann 2004-04-16 14:21:46 UTC]

The script is based on my situation:
I have three UMLs in a DMZ. (umlsquanto, umlarize105, umlxvaderx)
They are connected over tap devices to the host.

How do you propose that we package and make this available to gentoo users?

Added reference to this bug on gentoo-server@g.o email list. Was a discussion already there so I'm just trying to get some more feedback here.

I am not sure how, becauase this two init scripts are bugie suggestion, which work fine for my UML and my special setup. I wannted to give people, who are using UML and want to start it with init, a little help to write their own script. I got some good feedbacks in th uml-user mailinglist.

I could maybe imagine adding it to the UML-howto. And to fit it to the UML-howto network setup. Or just posting it in the gentoo forum with some explanations. Or just collecting some versions of init scripts for UMLs somewhere.

setup environment an tap devices for the UMLs

added to end of start:
  # for all
  iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
  echo 1 > /proc/sys/net/ipv4/ip_forward

added to end of stop
  # for all
  iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
  echo 0 > /proc/sys/net/ipv4/ip_forward

removed this variable

fixed this line to start as the correct user:
	start-stop-daemon --start --quiet --chuid 1000${UMLUID} --background
--pidfile /var/run/${UMLNAME}.pid --make-pidfile --exec /usr/local/bin/linux --
ubd0=${UMLHOME}root_fs ubd1=${UMLHOME}swap_fs ubd2=${UMLHOME}home_squanto
eth0=tuntap,tap${UMLUID},fe:fd:0:0:0:${UMLUID},192.168.0.25${UMLUID} >/dev/null
2>&1

stoping the UML should be changed to stop it with the UMLs mconsole

When Glep 15 - Gentoo Script Repository gets off its feet this is a good candiate for it.

James,

Is this a canditate for the script repository?

I never worked out a clean way of using them. Its here for reference and I hope it helps someone out Thomas.
