<0> How would I change ports on incomming packets... if a packet is coming in to port 111 and I want to redirect it to port 112 (UDP packets)? Im having some trouble making the REDIRECT target work
<0> im using string matching
<0> anyone know how to make string matching (-m string) case insensitive?
<1> Icemaann: I am sure -m string has NO idea about case, it prolly does dumb byte for byte matching
<0> Ikarus: yea, I think your right
<1> Icemaann: you could prolly really easily hack a dirty way of supporting it in there, but it would only work for plain-latin lettering
<0> Ikarus: yea, which is all I need. Im using it to match DNS packets based on what domain is queried
<1> ah
<1> Icemaann: well, you just need to add a match for: char + A - a (if I remember my ASCII correctly)
<0> Ikarus: yea, and then recompile the kernel module..... sounds like fun lol
<1> Icemaann: come on, you do know some C I hope
<0> Ikarus: im also having an issue with matching on periods.... Ive seen examples with matching on "cmd.exe" but when I try matching on something with a period it always fails
<0> i know some C, enough to be dangerous :-)
<0> Ikarus: im about to try --hex-string and match on the hex itself, maybe its a locale thing
<1> Knowing C at all is dangerous, but no idea why that matching would go wrong
<1> could be
<0> i set LANG=C, but who knows
<1> btw, I am actually wondering, doesn't string matching **** CPU power like there is no tomorrow ?
<0> Ikarus: yep
<0> Ikarus: temporary solution
