Hi, I'm trying to use rsync (2.6.8) through STunnel (4.16) to synchronize two PC over the internet (they both have the same version of stunnel and rsync). On the server, I have STunnel running with this configuration: cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=0 socket = r:TCP_NODELAY=0 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log [rsync] accept = 273 connect = 873 On the client I have this configuration: cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=0 socket = r:TCP_NODELAY=0 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log client = yes [rsync] accept = 873 connect = UrlOfMyServer:273 Then I connect with rsync using rsync -a -h --progress --stats --partial Account@localhost::RemotePath LocalPath I think the connection is not really stable. RSync sometimes hang. The log file on the client side show 2006.09.11 21:33:11 LOG7[2008:1468]: SSL_read returned WANT_READ: retrying at 30Hz (that's right, it means 30 times a second). My log file nearly gets bigger faster than my downloaded file ;) Is it expected? What does this line mean? I turned TCP_NODELAY to 0 thinking that it my give me synchronous sockets and that it would remove that error, but it didn't... Any help appreciated, Thanks -- Vincent
