I have a Beaglebone Black with a fresh flash of the 2015-03-01 Debian image (bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img) that I cannot scp or rsync large files to.
>From my Wheezy 64-bit host VM, I try to scp a 27MB file to the Beaglebone via ethernet and the transfer stalls out after <10MB The debug output from scp shows nothing but "debug2: channel 0: rcvd adjust [number]" notices. Searching the web suggests: - MTU mis-matches - no, both sides are 1500. - turning off tcp_sack - didn't help - Enable compression - didn't help - Try rsync - rsync fails, too - Try tar over ssh directly - didn't work - Upgrading scp/sshd - did "apt-get upgrade scp" and that freshened up a lot but didn't help. Log snippet is below. Any suggestions are appreciated. philmills@VM64:~/DEV/AUC/dist/BEAGLEBONE$ scp -vv -C ModTests [email protected]. d:/home/debian Executing: program /usr/bin/ssh host a.b.c.d, user debian, command scp
