...get() or copy(), or the case where the copy-data extension is used to copy data between files on a remote server without reading and writing it back over the wire. I?ve defined an extension called "ranges at asyncssh.com <mailto:ranges at asyncssh.com>? which is modeled somewhat after FXP_READDIR for getting valid data ranges in a remote file. Each call can return multiple ranges, but on files with a large number of ranges you may need call this new method multiple times to get the complete list. This allows for the copying to be interleaved with the range requests. The extension looks lik...

...I get a transport packet in which the sftp packet length field registers a length greater than the enclosing transport packet. In othet words sometimes I get a transport packet whose lenght is less than what the sftp packet length field registers. This happens only sometimes. That is, if I give SSH_FXP_READDIR commands say 30 times on the same directory, then I get this packet after around 25-30 iterations. I tried to check the readability of the socket when this happens but the server does not send anything after this and select just hangs. I am not able to think of why this is happening and would appre...
