List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org --0015174c35041e5f9004715c02d0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit When I scp or rsync a file several MBs from host Linux machine to guest Linux machine (both CentOS), the transfer starts at several hundred KB/s but slows down pretty quickly until it eventually "stalls". I've found a strange solution which is that if the guest machine pings the host at intervals then it keeps the connection from stalling (with a rate of about 10 to 20 KB/s). pinging works fine, but why does secure transfer have problems with maintaining a stable connection when transfering a single decent sized file? I've tried rebooting the machine to no avail :-( scp command used: $scp somefile.gz user@10.0.2.15:/directory_path/ rsync command used: $rsync -av somefile.gz --rsh=ssh user@10.0.2.15: /directory_path/ thank you, Atoosah --0015174c35041e5f9004715c02d0 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable
