[gentoo-user] Internal dynamic IPs

[gentoo-user] Internal dynamic IPs

[Roy Wright]

Howdy,

I have two machines that are regularly moved between two sub-nets. 
One a gentoo desktop, the other (boo hiss) that sorry excuse for an
operating system laptop.  Now the two subnets are my hardware VPN
at home, and the office.  Both machines need DHCP.  I also have a third
box (gentoo) at home on a static ip.  Now I mostly access the laptop via
VNC over ssh and via scp, rsync, and unison for file transfers.  We do
not have dynamic DNS available internally.  What I currently do is just
use nmblookup on the WINS name for each box and update the /etc/hosts
file (actually I use a down and dirty perl script to do the update).  This
works as long as I remember to do it prior to trying to ssh to the laptop.
If I forget, then sometimes the gentoo systems seems to get the old IP
stuck in cache somewhere where I haven't figured out how to clear it,
except by (gag) rebooting.  I know, my ignorance.

So I'm wondering if there is a better solution and also how to clear
the name server cache.

Thank you,
Roy

[gentoo-user] ffmpeg front-end recommendations?

[Ryan]

I am looking for an excellent ffmpeg front end/gui.  It doesnt matter if
its a console or X based front end, as long as it supports as many
features of ffmpeg as possible for decoding/encoding processes.  The
main purpose is to convert about 200 mp4's that I have into an SVCD/VCD
or mpg format with ability to play with the quality of the video.  I am
able to do it with the command line, but the lines are so long to edit,
that I'd rather have the buttons and dropdowns to select from instead. 
The ideal candidate I found would have been ffmpegX, but that is only
for MacOSX.  Is there something for Linux that is along the same lines
as ffmpegX that would use both mencoder and ffmpeg?

Sounds like a job for avidemux to me....

I tried that yesterday, but it didnt appear to load the video.  It sat
there trying to load, eating 99% of the CPU for about 20 mins.  The file
is only 136MB's and I wouldnt expect it to take that long on an AMD 2800
w/1GB ram.  It looked promising, but didnt seem to work.  The Mplayer
info on the file is below:
