Hey this isn't a fast link. :-) We only have a 2Mbit link, so even if I could convince the rest of the CSIR to do nothing, I could only hope to do 256kByte/s. :-) I wouldn't have thought that fast in US terms. But then they do not have the delay. :-/ > I'd suggest trying passive mode with "-P -" on the cvsup > command line. This may solve your problem, or at least help.

Does anyone know if ftp-master allow passive cvsup connections? I tried it, but cvsup just says this: Connected to ftp-master Falling back to protocol version 16.1 Cannot connect to data port: Connection refused Will retry at 05:59:18 Looking with netstat -a I see the second connection just stay in SYN_SENT state. Hmmm. Maybe I should go back to rsync at least for the packages. Would anybody mind if I run a cvsup and rsync simultaneously or do I have make sure I lockf them on the same file?
