UNIX/Linux: X11 connection rejected because of wrong authentication

 % ssh -X -l userid remotehost

remotehost% /usr/openwin/bin/xclock
X11 connection rejected because of wrong authentication.
X connection to localhost:10.0 broken (explicit kill or server shutdown).

If you encounter X11 connection rejected because of wrong authentication error after logging to an UNIX/Linux host through ssh with X11 forwarding option, -X, check your /etc/inet/hosts file for multiple localhost entries; and remove the unnecessary ones.

For example, my /etc/inet/hosts has the following entries when the xclock failed with an X11 connection rejected .. error.
remotehost% cat /etc/inet/hosts

127.0.0.1 localhost
::1 localhost
10.2.211.150 sunfiret2000 loghost

Removing the 2nd line, ::1 localhost, fixed the issue.

Kodak EasyShare M753/M853: Low Quality Grainy Pictures?

If the image size is around 500 KB even at 7 or 8 MP; and if the resulting image looks grainy, try this to improve the quality of the picture:

Turn off the Auto mode. Change it to manual mode and select ISO 80 or ISO 100. If there is no improvement in the quality of the picture, try the other ISO options 200, 400, 800 or 1250. Note that larger values doesn't necessarily produce cleaner, sharper images.

Twiki Tip: Viewing Meta Data in Page Source

Ridiculously short tip this time.

It would be very frustrating if the meta tags {like %META:FORM%} in a twiki page won't show up even the URL was appended by "?raw=on". The trick to show the meta data as well as the topic data is to append "?raw=debug to the twiki URL.

I'm still looking for a way to edit the meta data though.
