Hello,
I am having a problem with sftp transfer. I have the following test setup: 1. A machine which accepts ssh connections. 2. My machine which sets up connection to the first machine and transmits a large file. During the transmission of the file I unplug the network cable of machine 1. Program on my machine waits somewhere in sftp_write. After 20 minutes or so I plug the network cable. Program still waits in sftp_write and will do this forever! I debugged into this problem and noticed that ssh_channel_read_timeout is called with timeout = -1, which means infinite timeout. I am using the default blocking ssh_session and sftp_file. I am also using this: int timeout = 10; ssh_options_set(sshSession, SSH_OPTIONS_TIMEOUT, &timeout); Setting the sftp file to nonblocking changes nothing as the nonblocking flag is only used for sftp file read. When using ssh_set_blocking(sshSession, 0) even connecting the ssh session won't work! So how do I implement a SFTP file transfer, which runs into a timeout of 10 seconds if connection is lost and then returns?
