I also just noticed your application when i needed to distribute some source to a few machines for testing and the speed of unicast SCPs seemed to be a bad idea. Only problem is I have a heterogeneous environment -- so i needed the build to work under solaris. Well, i suppose the authors know -- it doesn't. I cooked up a few changes so that it appears to work for me and i wanted to contribute it to you. Where do I send it? Mike __________________________________ Do you Yahoo!? Yahoo!

udpcast for Solaris?
by John C. Fremont 20 Feb '04

20 Feb '04

Has anyone used udpcast under Solaris? I am trying to compile under Solaris 9 and have worked out the compile errors (I hope) and am resolving linker problems now. The hacks I've made aren't pretty and would break under IPv6 but. I was hoping someone may have already done a port. Thanks for any assistance. John

Etherboot/PXE questions
by Donald Teed 17 Feb '04

17 Feb '04

I tried udpcast a few days ago and it worked well. The full duplex option to udp-sender was important to making it stable in my test. I have a couple of questions... 1. (not exactly a udpcast question, but related...) How can I set up DHCP/TFTP so that it doesn't require a specific MAC address to direct a machine to the pxeboot image? 2. How can I provide the etherboot/PXE client machine with the menu file for udp-receiver? 3. Can the DHCP/TFTP server be different than the box running udp-sender? (Were the same in my test). I'm investigating how this can be used to image 4000 laptops for a University, and in this case a bootable floppy or CDROM is too cumbersome. --Donald Teed

Cisco routers, at the least, do not forward packets destined for 224.0.0.1, which is the default for udpcast. Changing this is required for clients to find one another. That point aside, thanks for the useful software and for bearing me out these 5 months ago. regards, Chris

Hi, I would like to know if there is a solution to get udpcast working with NVIDIA nForce MCP Networking Controller. SysRescCD uses nvnet driver with this card. I didn't find it on cast-o-matic. Can you help me? Thank you very much. -- Stephane ********** PROTEGEZ VOS E-MAILS !********** Avec Tiscali SuperMail, vos e-mails en toute sécurité !
