Kan man ikke lave en regel i shorewall der kun giver adgang til
port 22 fra bestemte adresse?


Det kan man jo nok godt.  Men det vil stadig også være værd at
gennemføre en tilsvarende spærring i SSH-dæmonen (i fald der er
huller i Shorewall).


Jo, men nogen gange vil man jo netop bruge ssh som sftp i stedet for
ftp.  Så kan man ikke lige bruge tilladte adresser.


Nu har du tabt mig.  Kører SFTP ikke også på port 22 sammen med resten
af SSH-protokollen?

Jacob
OK, jeg svarede lidt kort. Jeg mener hvis man vil have mange der skal kunne uploade f.eks til webserver og ikke vil bruge ftp, bliver det lidt svært at liste tilladte adresser.
