[Message part 1 (text/plain, inline)]
Package: x2goclient
Version: 4.1.0.0
Severity: grave

When you install X2GoClient on Windows in portable mode, in the
directory some_dir\x2goclient, and create a batch file to start it in
porable mode as some_dir\x2goclient.cmd, with the following content:

@echo off
cd /d %~dp0\x2goclient
start "X2GoClient" x2goclient.exe --portable

Then, either upon connecting to a server (causing ssh\known_hosts to be
created/updated), or upon closing of x2goclient, the content of these
directories gets deleted (save for the file ssh\known_hosts):

some_dir\x2goclient\.ssh
some_dir\x2goclient\ssh

Obviously, this is NOT good, because people will be tempted to store
their private keys in that directory, only to find them gone afterwards.

My guess is that it hits .ssh as well because .ssh is no regular FAT
file name, but rather one that can only be created in cmd.exe with "md
.ssh", and probably only works on VFAT, not regular FAT, so a routine
looking to match ssh that isn't VFAT-safe will hit .ssh instead.

Could it be that we have a bug in x2goclient that purges the ssh
directory whenever known_hosts is accessed for writing, or similar?

Kind Regards,
Stefan Baur
