Feature Requests: named sessions and no timeout messages
by Don Bright 27 Jun '06

27 Jun '06

Dear UDP Casters, First let me say thank you for making this program. It has enabled me to completely get rid of Symantec Ghost and it's damnable boot floppies, as well as extremely hard to understand licensing arrangement (I was never sure if I had a legal copy or not, someone else at the workplace just gave me a copy of it, and I couldnt get any information on the license for it) I have two feature requests. The first is to have an option, something like --name, which would provide a 'name' for each 'session', so that if two people are using udpcast on the same network, they wont conflict with each other. I know they could just use different ports, but names seem easier than ports (and certain ports might be blocked or conflict with other programs) The second, is to have a command line option to stop the 'timeout' messages on the sender. I'm sending 7 GB of data and getting 1% timeout (maybe because im sending to some old machines) so you can imagine the massive amounts of messages written to the console. I'd like an option like --quiet or --hide-timeouts to stop this stuff. I might make a patch later on, but I thought I'd through this out there in ccase someone has already done it or its being planned. Thank you.

Ejecting the CD-ROM before broadcast
by Yannick Gingras 26 Jun '06

26 Jun '06

Hi, I'd like to have my udpcast to eject its CD-ROM before a broadcast so I can pick it and boot another box with it. Yeah I could just push the CD-ROM drive button but I'm a lazy bum. cast-o-matic is a great tool so I though I could just upload eject and call it. Ok eject is overkill, I did a smaller eject that I call miniject: #include <unistd.h> #include <stdlib.h> #include <stdio.h> #include <string.h> #include <fcntl.h> #include <limits.h> #include <sys/ioctl.h> #include <linux/cdrom.h> #define DEF_CDROM "/dev/cdrom" int main(int argc, char **argv) { int fd; if (argc > 1) fd = open(argv[1], O_RDONLY|O_NONBLOCK); else fd = open(DEF_CDROM, O_RDONLY|O_NONBLOCK); ioctl(fd, CDROMEJECT); } But unfortunatly I can't find the cdrom device in /dev. Are there any modules that I should add to the image in order to have the cdrom device created in /dev ? -- Yannick Gingras

online-Interface e1000 problems
by Dieter Kroemer 22 Jun '06

22 Jun '06

Hi, after creater in the online interface an image for the intelpro1000-nic I get after startingthe computer with udpcast following message: /lib/modules/2.6.11.12udpcast/modules.pcimap (No such file or directory) --> after klicking okay: mod probe: could not parse modules.dep. I've got an older udpcast image (from december 20005) for the e1000, there are no problems. (I need a newer image, because the computer have to resart after finishing the cloning.) What can I do? Kind regards Dieter

Hi list, I downloaded a new image of udpcast and had to find out that support for FAT-filesystems seems to have gone away. Is there a way to get it back? Thanks Gerhard

cap=00000009 message once at beginning of transfer
by D G Teed 20 Jun '06

20 Jun '06

Hi, We have a new notebook to image. I have started testing of the send of the master, and initially the receiver got a message : received message, cap=00000009 then it shows it is connected and the IP and the rest proceeds without a problem. The sender showed: Starting transfer: 00000009 and then the stats on bytes transfered proceed without error. The connection is over a crossover cable - no switch/hub. Is there anything to be concerned with in that cap= message? --Donald Teed

Trouble with a 3com-812 router
by Paco Cruz 14 Jun '06

14 Jun '06

Hello all I a have setup udpcast in a classroom at a Secondary School to distribute CDs and whole directorie trees, and it works like a charm, except for a minor nuissance. Everytime I want to use udpcast I have to disconnect from the 3com-812 router that serves as a gateway. When I try to send anything with the gateway connected there is an extremely low transmission with errors el al. As soon as I disconnect the router the throughput goes up to 70-90 Mbps. Does anybody have any hint? Thank you all -- Saludos Paco Cruz --------------------------------------------------------------------- "If you have an apple and I have an apple and we exchange these apples then you and I will still each have *one* apple.
