aux/vga doesn't serve it; #v/vgactl is the kernel's exposed interface
to its part of the vga graphics support.

Wouldn't it make more sense for aux/vga to serve /dev/vga* after
initialising the environment?  I suppose the right answer is "Try it",
or am I missing something?

[9fans] charon / tcp pasthrough sniffing

[Matt]

I'm trying to defeat all the shenanigans on www.genie.co.uk in order
to send sms messages without having to use the website

they use some tricky techniques to prevent scripting such as a random
redirected url and 6 cookies!

I thought I'd worked it out but no.

I'm about to sniff the tcp to see what exactly the browser sends to
the site so I can script it

Is there some general purpose tcp sniffing technique I can adopt with
the clever use of cat /net/tcp/N/data or something?

I tried a tcp passthrough last time I worked on this but never got it
working!

any help out there?

TIA Matt

I'll always carry my first language with me and will never learn to
disambiguate English sentences.

I meant: "Would it make sense for aux/vga to set up the VGA
environment - based on a much simpler kernel device - and then serve
/dev/vga* itself?"

Have you already set web browsers aside and spoken directly with the
web server (via HTTP) to see what _exactly_ it's doing?  I've been
known to resort to this (using libwww-perl, but there are other
ways to do the same thing) for particularly intractible websites.
