[vfs] UnkownHostKey
Hello,
Im am trying to establish an SFTP connection to an SFTP Server
(shell.sourceforge.net) with JCommander (jcommander.sourceforge.net),
which uses the commons vfs. Unfortunately I always get a
FileSystemExecption: "Could not connect to SFTP server at
"shell.sourceforge.net: UnknownHostKey: shell.sourceforge.net". Other
people are able to use JCommanders SFTP without any problems, but I
don't know, what I am doing wrong.
Although I read the documentation, I do not yet fully understand the
hostkey mechanism. Don't vfs create needed hostkeys on its own, possibly
after asking? I think I have read somewhere, that hosts are saved in
$HOME/.ssh/known_hosts. But this file does not exist, and creating it
does not help either. I found the function
SftpFileSystemConfigBuilder.setStrictHostKeyChecking(), but I did not
find any information about how to use it, as JCommander uses the
FileSystemManager VFS.getManager(). But actually I should not have to
change anything in the code, as other people are able to uses it without
problems.
Any help would be very appreciated,
Matthias

There are some ftp clients that automatically add entries to
$user_home/.ssh/known_hosts, but none of my clients on Windows do that. If you
set strict host key checking to 'false', then JSCH, the library that provides
VFS with SFTP functionality, will write the host key to known hosts. After
that, you won't need to set that flag because it will just read the host key
from known_hosts.
