Stava, no ne mi vurshi rabota zashtoto :

- Na mashinite azd gateway-a njamam pulen kontrol, t.e. ne moga da slagam ssh clienti i prochee, mashinite sa Windows, SCO UnixWare, pak Linux ili IBM AIX - vsichki imat ftp client standartno.
- NE ISKAM useri da imat accounti po gateway-a, izklucheno e. Za tjah trjabva da bude prozrachna jalata istoria - te prosto uploadvat file na ftp server.
- Vsichkoto tova trjabva da stane po dial-up linii i poneze ne iskam da pipat userite nishto - dial on demand.

Dotuk pingvam neshto si i pppd-to dialva, sled zadaden timeout bez trafic si dropi t.e. OK e.
Opitvam se da izmislja, kak pri iniciirane na ftp sesia ot client da se iniciira i ssh tunel kum servera, tova ot svoja strana da vdigne ppp-to, da si svurshi rabotata i da dropi.

Take care
