Bug#411187: tightvncserver: can not use symbolically linked ~/.vnc/ directory or ~/.vnc/passwd file

[Jussi Judin]

Package: tightvncserver
Version: 1.2.9-21
Severity: normal
Tags: patch


When trying to start tightvncserver when my ~/.vnc/ directory is a
symbolic link, I get the following message:

tightvncserver: Wrong type or access mode of /home/jussi/.vnc.

This is due using lstat() function in tightvncserver starting script to
check if file is a directory instead of stat(). Same for ~/.vnc/passwd
file. Following patch fixes this.

This is similiar to bug #411185 for vnc4server (they are using
similiar vncserver file after all).
