[gentoo-user] How to have init-scripts 'wait' for other servers
Hi all, Does anyone know if an existing method to have init-scripts on server A wait for a service on server B to be started? Reason for this: I have one server containing all the databases, one that operates as a NAS and the DNS is running on server 3. In order for the different machines to start correctly, I need to configure it that server 3 starts the DNS before the other machines try to access other machines (don't want to maintain hosts-files as it all works fine once the servers are up and running) Also need to make sure the database and NAS is running before the webserver starts. I tried to google for it, but I can't find a usefull search string that will give me anything usefull. I don't mind reqriting init-scripts for this, but am looking for a way to check if services are up and running from within the init-scripts. Thanks, Joost Roeleveld

I have no idea if this would work or not. But have you tried writing a init script that does nothing but polls for the service and only exits when succeeds? Then you can edit the scripts for the dependent services to require it to start after your polling script. Something like: script /etc/init.d/foo polls tries for database connection. Inside it is a time-delayed loop that tries until it succeeds. Edit /etc/init.d/apache (assuming you are using it for your webserver) to 'need foo' Again, I am just throwing this out randomly. Let me know if it works at all ;p Best of luck, W -- Two college graduates are peeing in a bathroom. The Harvard grad finishes, goes over and washes his hands very well using lots of soap and water, and says at Harvard, they teach us to be clean. The Yale grad finishes, and washes his hands with a very small amount of soap and water and says at Yale they teach us to conserve resources. Right then, a Princeton grad walks in, washes his hands thoroughly, and goes to the urinal, saying At Princeton, they teach us to wash our hands before handling a sacred object.

Then you can edit the scripts for the dependent services to require it to start after your polling script. I have been thinking of something similar, but before starting to write this myself, I wanted to double check if anyone has a better idea and/or already knows of a set of scripts/tools that already implement this. Something like: script /etc/init.d/foo polls tries for database connection. Inside it is a time-delayed loop that tries until it succeeds. Edit /etc/init.d/apache (assuming you are using it for your webserver) to 'need foo' Or, obviously, fails if it doesn't come up within a certain (configurable) time. Again, I am just throwing this out randomly. Let me know if it works at all ;p If there is no existing set of scripts, I will share whatever I come up with. Best of luck, Thanks, Joost

Thanks, Joost Roeleveld Monit may be able to meet your needs and reduce the amount of work you'd have to do to script this up yourself. http://mmonit.com/monit/ An advantage of not touching the init scripts is that you don't have to maintain patches or deal with merge prompts when a package updates it's init script.

Regards, Carlos I will have a look at this. From the website it looks like it should be able to do most of what I need. Might need to reconfigure a few things (like not starting all services using the 'normal' method, but I can live with that as long as monit can still tell me what is running and what isn't... (added bonus, it's in portage: app-admin/monit ) Thanks, Joost

[gentoo-user] How to have default fedora font in gentoo ?
Hi, i'm searching the fedora/redhat default terminal font (maybe Luxi Mono ?) to use in my Gentoo Box. I've tried Luxi Mono following X11-font HOWTO but it doesn't look very well. Any idea ? Thanks, Max. -- gentoo-user@gentoo.org mailing list
