[syslinux] which should I use: TIMEOUT, ONTIMEOUT, or ONERROR ?
Hi. I'm trying to get around the problem of an overloaded tftp server causing a pxelinux client hanging at the boot: prompt, waiting for input (no one will input anything to it). The server is OK enough to give the pxebootloader but not the config file, as in this thread: http://syslinux.zytor.com/archives/2004-June/003662.html So, in that case, I guess setting TIMEOUT to some reasonable positive value would help. But, assuming it never got a config file, how would i get the box to automatically reboot or localboot? ------- Cheers, Anthony

Newer versions of pxelinux consider it a fatal error to not fetch its configuration file, and triggers the "reboot after five minutes" (which can be adjusted via DHCP option 211.) -hpa

on second thought, I don't think any of these options will help that case since, I think, the problem is that the pxelinux binary gets to the booting client but the config doesn't. I guess it's cause the retries and timeouts of the PXE firmware in the NIC/BIOS are more forgiving than that (PKT_RETRY and PKT_TIMEOUT) of pxelinux?

Thanks so much. So do I have to send dhcp option 211 or is the default 5 mins? ----- Original Message ----- From: syslinux-bounces at zytor.com <syslinux-bounces at zytor.com> To: For discussion of SYSLINUX and tftp-hpa <syslinux at zytor.com> Sent: Tue Apr 22 14:32:04 2008 Subject: Re: [syslinux] which should I use: TIMEOUT, ONTIMEOUT, or ONERROR ?
