Operating Systems Linux Session "hijacking" - Recover lost session Post 302523729 by DGPickett on Thursday 19th of May 2011 02:50:47 PM

I dono't think so, which is why I prefer to have an Xvnc on each UNIX box. If I lose connection, or go home, I just reconnect to my vnc desktop. Depending on settings, two or more can connect to same desktop. If a box is rebooted or crashes, I lose only the local desktop.

You can tusc/truss/strace into your old processes, if you want to try to collect output of such. This generally slows them down. If they start writing to the dead terminal, they may die before you see anything.

NAME
vncpasswd - change a VNC password SYNOPSIS
vncpasswd [passwd-file] DESCRIPTION
vncpasswd allows you to set the password used to access VNC desktops. It stores an obfuscated version of the password in the given file (default $HOME/.vnc/passwd). The vncserver script runs vncpasswd the first time you start a VNC desktop, and invokes Xvnc with the appro- priate -rfbauth option. vncviewer can also be given a password file to use via the -passwd option. The password must be at least six characters long, and only the first eight characters are significant. Note that the stored password is not encrypted securely - anyone who has access to this file can trivially find out the plaintext password, so vncpasswd always sets appro- priate permissions (read and write only by the owner). However, when accessing a VNC desktop a challenge-response mechanism is used over the wire making it hard for anyone to crack the password simply by snooping on the network. FILES
$HOME/.vnc/passwd Default location of the VNC password file. SEE ALSO
