Mime Util updated SSHD-402:
---------------------------
Description:
I set up a sshd-server als follows:
{code:java}
this.sshd = SshServer.setUpDefaultServer();
this.sshd.setPort(2023);
this.sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("keys"));
List<NamedFactory<UserAuth>> userAuthFactories = new
ArrayList<NamedFactory<UserAuth>>();
userAuthFactories.add(new UserAuthNone.Factory());
this.sshd.setUserAuthFactories(userAuthFactories);
this.sshd.setCommandFactory(new ScpCommandFactory());
List<NamedFactory<Command>> namedFactoryList = new
ArrayList<NamedFactory<Command>>();
namedFactoryList.add(new SftpSubsystem.Factory());
this.sshd.setSubsystemFactories(namedFactoryList);
{code}
After starting the server, I upload a file (scp -P 2023 filename.txt
localhost:) containing:
{quote}
1234567890
{quote}
Afterwards I remove "234567890" from the local file an upload it again. Instead
of containing on "1\n" the file contains:
{quote}
1
4567890
{quote}
It seems that "23" is replaced by two spaces, and the rest of the original (on
the server) remains in the file and is not overwritten.
