Hi Turner
I will help where i can mate!
Q1 : nano command will work in terminal which will open a very basic editor any changes you make ctrl x to exit and save, if your using desktop the editor is fine, just remember the oscam files will not save auto, you
may have to save to /tmp the in root in terminal cp /tmp/fileyouwanttomove /etc - directoryyouwant to move to
Alternativly if you want to edit files say from another PC you can use notepad (not best) or notepad ++ (better) just ensure that you save the files as all files with the correct format i.e oscam.conf, notepad ++ deals with this better
so you may wish to try that. (note...Notepad ++ save as > on drop down box scroll UP to all files sometimes catches people out)
From there you can drag and drop on to usb and copy to server or log in using winscp and ftp acros to correct location.
Just remember when playing with Oscam/Cccam files often a restart will make the change happen.
Q2 Matter of choice, most use Oscam to read/update card and Cccam to share lines e.t.c some go with just Oscam some use others, probably start with both, see how you get on and make changes from there i would suggest, but depends
on what you plan to do/share e.t.c then there are the versions so best to post what your setup is, card you plan to share e.t.c to point in right direction as some cards may be effected by version?
Q3 I presume you have looked here Forum Gateway - Powered by DnP Firewall You should find your configs here, anything you are not sure with let us know exactly....
Q4 although i have one i dont use Omnikey, Smargo was first out the box :) hopefully someone should add to this!
Bit long winded but should lay some big crumbs for you to look for!
Have Fun, You will Love It
