Logan updated SSHD-927:
-----------------------
Description:
Sftp put fails if the file already exists on the sftp server, terminating the
sfp session immediately.Below is the simple configuration to reproduce
{code:java}
SshServer sshd = SshServer.setUpDefaultServer();
sshd.setPort(9999);
sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider());
sshd.setSubsystemFactories(Arrays.asList(new SftpSubsystemFactory()));
sshd.setFileSystemFactory(new VirtualFileSystemFactory(new
File("C:/temp").toPath()));
sshd.setPasswordAuthenticator(AcceptAllPasswordAuthenticator.INSTANCE);
sshd.start();
{code}
{noformat}
C:\temp>sftp2 test@localhost#9999
Host key for the host "localhost#9999" not found from database.
The fingerprint of the host public key is:
Babble: "xodec-damen-ripeg-hehuh-venep-pebys-zureg-rynit-mypiz-byheh-zixax"
RFC4716: "1d:4f:c2:a4:fe:58:93:61:fe:44:69:26:f2:41:34:f7"
You can get a public key's fingerprint by running
% ssh-keygen-g3 -F publickey.pub
on the key file.
Please select how you want to proceed.
cancel) Cancel the connection.
once) Proceed with the connection but do not save the key.
save) Proceed with the connection and save the key for future use.
Please select one (cancel, once, save): once
test@localhost#9999's password:
Remote system type is POSIX.
sftp> put ndp46-kb4483451-x64_41ba9b8a814351a318e78e4e1c02adc7e9fff67a.exe
Error: Connection lost.
{noformat}
Upon Debugging I found the SftpSystem is terminated because the file channel
received close command ( see attached )
Added event listener to see reading and read method are called but no
writing/write methods are never called.
