I’m having problems with upload via FTP, so I tried telnet. (Shell access is the reason I picked Dreamhost, actually.) But there seem to be no software available (not on the path anyway) for file transfer. Typically this would be zmodem (rz and sz), or maybe Kermit, but none of these seem to be installed or available. Can anyone advise me on how I can upload/download files via Telnet?
zmodem won’t work.
You could try scp or sftp though. See the kbase article for information on various forms of secure file transfer, including some GUI front ends for scp.
