Hi list (and happy new year),
I'm experiencing some troubles using Samba (4.1.17 debian version) over
VPN. Basically we've following setup :
PC === LAN ===> VPN (WAN) ==== LAN ===> Samba file Server
Copying big (say > 1MiB) files from PC to Samba file server almost
always ends up with a NT_STATUS_IO_TIMEOUT error (or "a network error
occured" if trying to copy from a Windows box).
It seems that Samba cannot cope with the fact that LAN speed is way
higher than WAN one (thus filling buffers an not waiting for WAN link to
consume them).
Copying from PC to a Win2003 server on the same LAN as Samba runs
smootly, Windows copy window indicates a copy speed matching the WAN
link speed whereas when copying to samba it shows 1 or 2 seconds bursts
then 30s at 0kb (waiting for WAN tramission).
Tested on several Samba servers (oldest one is 3.0.24 (…)).
Has anyone encountered this kind of issue ?
Regards
