Hi, I was wondering if could be possible to add a cmdline option in /tftpboot/udpcast/pxeslinux.cfg/default to pass configuration file options, like auto=yes lang=US kbmap=US netmodule=pcnet32 netmodparm= dhcp=yes port=9000 disk=/dev/hda mode=0 udpcparam= Something like label linux kernel linux append load_ramdisk=1 initrd=initrd root=/dev/ram0 conf=auto:yes:lang:US:kbdmap:US ... and so on ipappend 1 I would like to add ca_ES lang suport, also spanish keyboard map, how can i do it ? Thanks in advance -- ... en el país de los ciegos el tuerto es el rey y diciendo esto se arranco un ojo ...

Hello all I am using udpcast-20070218-1.i586.rpm on OpenSuse 10.2 It seems that I can transfer (iso) files without problem, but I am unable to transfer directory trees through a pipe. commands # udp-sender --log log.txt --pipe "tar -cvzf - dir/" # udp-receiver --log log.txt --pipe "tar -xvzf - " I keep getting the following error in the receivers ---------------------------------------------------------------- amd:/some/dir # udp-receiver --log log.txt --pipe "tar -xvf -" Udp-receiver 2007-02-18 Compressed UDP receiver for (stdout) at 192.168.1.2 on eth0 received message, cap=00000009 Connected as #0 to 192.168.1.4 Listening to multicast on 232.168.1.4 dup2 -1->1: Bad file descriptor Press any key to start receiving data! ---------------------------------------------------------------- the sender shows the following line repeated ---------------------------------------------------------------- Timeout notAnswered=[0] notReady=[0] nrAns=0 nrRead=0 nrPart=1 avg=9106 ---------------------------------------------------------------- and the transfer stalls. The logs are empty in sender and receivers Any idea out there? :-) Thanks you all.

Mirroring files, security, etc.
by Forrest Aldrich 06 Mar '07

Is anyone using UDPCast to periodically mirror files... ? I see a couple of older (2003) posts that ask somewhat similar questions; however, we have a series of media files (some very large, like a few gig) that need to be mirrored to a few hosts on a periodic basis. Hopefully, without overloading the link in the process. Anyway, we plan on mirroring files that are current within 48hours. Easy to build up that file list. I might be concerned about specifying "download, then overwrite" or "don't download if exists" and such (rsync can do some of these things). Obviously, there's little sense in mirroring files if they already exist. I'm also concerned about security. We have a mix of Unix and Windows servers that will be utilizing this process (whatever it ends up being). Apart from individual firewall rules, what's the best way to secure udpcast from unwanted activity - this is a private network, but still prudent to secure any open services. Thanks.

error: dup2 -1->1: Bad file descriptor more data

If you don't use the "--file" option the resp. file descriptor is -1. Solution is simple: specify both, --file and --pipe. Have fun! Björn
