Hello. Thanks for developing udpcast. It almost compiles on my mac. But I have to make a few small changes. 1.) the linker doesn't support the -Wl,-warn-common option 2.) what is malloc.h? It isn't needed. 3.) struct ifreq is variable size, so we must use _SIZEOF_ADDR_IFREQ (), not pointer arithemetic 4.) some endian issues Thanks, Devin Bayer

Re: [Udpcast] a bug from UDP-sender.exe under WinXP?

by Haiwei Sun

Dear Mikes: Thanks for your suggestion. I tried to turn off my firewall. However, it comes out with the same error. Could we fix port to 5004 only to all receiver, So that all receiver can access the same IP:Port to get the same data? Best Regards, Haiwei > -----Original Message----- > From: Michael D.

config file from pxe

by Lluís Gras

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 ...

error: dup2 -1->1: Bad file descriptor receiving piped tar data

by Paco Cruz

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.

Using UDPCast for transferring files...

by Forrest Aldrich

Where I work, we have a regular series of large (20gig) and small (*.rm) media files that we often need to transfer en masse to other systems. It makes sense to find a tool that can do this with multicasting... this isn't really doing any OS imaging or installation, however. I'm concerned about leaving UDPCast running; even though it's on a private network, it's wide open (potential security issues). In any case, can it recursively copy a directory structure or must you supply it with individual file names, etc. For example, we have a "media" directory where new files are deposited, and those must be mirrored exactly to the other systems, under the same directory structure. And to add spice to this, we're transferring from Unix to Windows Servers (which uses Cygwin) ;-) Thanks.

udp-sender.exe (window version) needs to be updated

by Haiwei Sun

Dear All: This is Haiwei from Singapore Panasonic Laboratories Pte Ltd. I just tested -daemon-mode using udp-sender.exe (window version) under winXP. Below is the command used and its corresponding results: [command] udp-sender -M 239.1.1.1 -P 5004 --daemon-mode --nokbd --autostart 1 -f test.txt [results] Udp-sender 2007-02-18 Using mcast address 234.81.112.185 UDP sender for test.txt at 10.81.112.185 on Intel(R) PRO/100 VE Network Connecti on - Packet Scheduler Miniport (00-00-e2-5b-c7-66) Broadcasting control to 239.1.1.1 Starting transfer: 00000009 Transfer complete. bind socket to 10.81.112.185:5005 (Bad file descriptor) [my comments] There is no need to call bind() again when transferring is terminated. Next receiver should share the same IP:Port as 10.81.112.185:5004? I have tested udp-sender (2006.9 version) under Linux (Fedora 5.0), it works well. So I doubt that udp-sender.exe (window version) may need to be updated. Your comments are welcome. Thanks in advance. Best Regards, Mr. Haiwei Sun R&D Engineer Panasonic Singapore Laboratories Pte Ltd Singapore

Hello all I have "downgraded" to udpcast-20060619-1.i586.rpm... and the transfer works! For me it is OK to be "a year back", but working :-) Thanks again

problem : File "null" has more lines than expected, ignoring the end.

by Salatiel Filho

Hi guys , i am really newbie with udpcast and i have a very annoying problem with my custom kernel built using udpcast-mkimage-20070205-1.i586.rpm Well , i have compiled my kernel and it is working , the problem is every time udpc_dialog shows i get an alert right after slect keyboard option : --------------- ALERT ---------------------- File "null" has more lines than expected, ignoring the end. This is really annoying because i can not make a full automated "deploy", because even when i give a full AUTO config file i still get that error and need press enter to continue. Is there a way to fix this ? have i forgot something? Thanks in advice ... -- []'s Salatiel "O maior prazer do inteligente é bancar o idiota diante de um idiota que banca o inteligente".
