- I need some help/advice on limiting Telnet and FTP access to my machines
- under 2.0. Basically what I want to do is allow only those users coming in from
- a "trusted" host (for the most part, our domain, only) access to the machines.
- I think I have the Telent taken care of by putting some code into sylogin
- and grabbing tt_accpornam. I then do a search against a file of valid inet
- addresses and if there isn't a match, the user is logged out.
- My problem is getting FTP to do the same thing. tt_accpornam is never filled
- by the ftpd process and I have come up with no other way to solve this problem.
- Has anyone out there in netland done any "filtering" like this? Any input
- would be greatly appreciated.
