Hello, We'd like to use udpcast to distribute approximately 20G of data to ~100 machines on a daily basis. We currently have 72 machines, but usually only 40-50 of them successfully transfer data. The command lines look like: udp-sender --max-bitrate 45m --full-duplex --min-wait 300 --pipe "tar -c -f - source_directory" udp-receiver --pipe "tar -x -f -" We have a cron job which monitors a directory in NFS for a flag file, and when the flag is raised, the sender starts up, and after a short random timeout, the receivers start up. The receivers write messages to syslog, so I can verify that they're starting up before min-wait expires. Lengthening min-wait doesn't appear to have an effect. We're on switched fast/gig ethernet. Are there any reasons why the sender wouldn't be able to "see" more receivers? Thanks in advance.
