Re: 8-STABLE outgoing scp stalling frequently.
I run a similar network setup at home, and am unable to replicate your experience regardless which host is being copied to/from. Perhaps you have a more specific issue eg nic driver ? I missed the start of this thread, but I have also seen scp stalling on 8-STABLE, except in my case it as inbound ... i.e. uploading to the FreeBSd machine. The client was scp on OSX, though I also saw the same issue with rsync, leading me to belve taht the problem lies somewhere in ssh. In the end I just used NFS and didn't worry too much about it, but just a me too to show it's not just the OP. Mu machines were also directly connected to the same switch on the same ether. -pete. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
