download of sysrcd.dat stalled while downloading [solved]

Postby PoisonNuke » 23 Mar 2011, 12:17

Hello,

I have updated my network book from sysrescd 1.53 to the most current version 2.01

With this version, the download of the .dat file via HTTP is stalling every time with every file. It hangs on the last bytes and tooks about 10sec to continue.

Any ideas why the download via HTTP have such problems?

thank you in advance

Use you the sysrcd as dhcp/http server.
Which bootrom use you?
Are there a additional router with dhcp or nameserver in the subnet?
Use you the automatic generated /tftpboot/pxelinux.cfg/default ?

Hi, I had the same problem, with every version after 1.6.4 (I've tried them all, up to and including 2.5.0-beta004).

Luckily, I also found the cause and a work-around. The busybox wget version seems to stall when your server is setting HTTP Keep-Alive. Disable it on your webserver (or just for the sysrcd location if you actually need Keep-Alive for other stuff) and your downloads will fly again :)

Thank you for posting hopla... no telling how long I would have been poking around trying to figure out why this stalling was happening without being able to figure it out.

Any chance of getting a newer busybox version that does not suffer from this problem in the next Sysrcd release?
We cannot alter the configuration of the webserver we use.


The busybox Sysrcd includes in its initramfs is ancient.
Issue was fixed in Busybox back in 2011: https://bugs.busybox.net/show_bug.cgi?id=3217
