Hello all -
(Please forgive me if I sent this msg twice, first one didn't seem to go through)
I searched through the archives and did not see anything about this (along with google), but if I missed something please don't hesitate to send me some links.
Basically I have hit a problem that I cannot figure out at this point and seemed to have ran out of ideas via Google or the documentation.
I am kickstarting (using cobbler) CentOS 6.2 installs over a private network (can reach the Internet). Part of the installations is to go grab various configuration files, rpm's, etc that are located both internal to the network (different subnet) and externally on the Internet somewhere. This problem seems to be intermittent since it works half of the time, but not the other half.
Any of my kickstart scripts I have that use local commands (not wget'ing files) work just fine no problems. However when it comes to getting things from the network, it does not always get those files. Usually this errors out with a cannot resolve hostname error or no route to host. I have tried the following to overcome this:
1) During post-install, add a network start and sleep for 120 seconds to give it time to come up.
2) Made sure that the "network" commands in the kickstart included -activate
3) Tried making the downloads not depend on DNS which still does not work (no route to host).
Are there any tricks to ensuring the network comes up during post-install for kickstart?
By the way, after the kickstart is done and the VM boots up, there are no changes that need to be made to get the network up and running like normal... DNS, etc work fine immediately.
Thanks for any help,
Daniel
For your RPMs, I'd definitely suggest setting up your own local repos within Cobbler and serving up that way on install - each repo doesnt have to be used for each system you configure...or it can be...
For your files - you might consider using Puppet and have it deploy them post install from a Puppet master?
I know this isn't exactly what you are asking about - just though I'd mention it in case its worth while - as I sort of do something similar myself but using Cobbler/Puppet....

Hi Scot -
Thanks for the response. Long term goal is to put Puppet or Chef in place so definitely know that is the direction I want to go, just a matter of finding the time to put it in place.
RPMs - probably would be smart move to do it through cobbler even though the mirrors are local, might play a little nicer..
Problem is that until I can get puppet/chef put up the files bit is still likely to be a problem, and if I can fix that then the RPMs would most likely get downloaded properly too.

Daniel,
I hear ya... I've spent sooo much time playing with Puppet/Cobbler - a lot of time - its been worth it :)
If you go the route of the RPMs in cobbler - maybe you can just copy your config files to the cobbler machine as well and serve them up that way too - doesn't necessarily have to be in a cobbler repo - but Apache is running there too...and you could easily wget them from there...
