| fish_ | I'm trying to pxe boot the precise installer but it says: IP-Config: no response after X seconds - giving up (but still retries somehow ;)) | 14:53 |
|---|---|---|
| fish_ | anyways, I see the request and offer in the dhcp server log (dnsmasq) | 14:53 |
| fish_ | not sure why it's not accepting the offer. any ideas what could restrict it? | 14:54 |
| fish_ | and obviously dhcp seems to work, since it has booted pxe booted the installer seconds ago just fine | 14:55 |
| devicenull | fish_: is it a cisco switch? do you have portfast enabled? | 15:27 |
| fish_ | devicenull: yes it's a cisco switch but I never heard of portfast. but it's a managed infrastructure (rackspace), so it might be enabled. I'll ask the support | 15:30 |
| devicenull | if portfast is disabled, you'll generally see intermittent timeouts for dhcp | 15:30 |
| devicenull | it's disabled by default, dunno if rackspace turns it on | 15:30 |
| fish_ | devicenull: but it wasn't a intermittend timeout, it keeps retrying several times (dhcp server sends an offer each time) but it never send a request/binds the ip | 15:31 |
| fish_ | but I realized that there are two dhcp servers. eth0 = my dhcp server, eth1 = rackspace dhcp server | 15:32 |
| fish_ | sure, I need them to disable their dhcp server. but the behaviour is still confusing | 15:32 |
| devicenull | isn't there an option to specify which interface to use? I don't know a ton about the ubuntu installer, but centos has 'bootif=eth0' as a kernel parameter | 15:34 |
| fish_ | devicenull: unfortunately the order of interface isn't stable, so you can't really know which interface eth0 is | 15:35 |
| devicenull | ah | 15:35 |
| fish_ | you can specific the mac, but I don't know the mac before booting | 15:35 |
| fish_ | but I just booted the installer with 'break' to get a shell and it seems ipconfig works fine when executing manually | 15:36 |
