I need a way of allowing only certain IP addresses the ability to telnet to our system on port 23. This would be until the time that they can upgrade their client.

So as an example, we need an exit program to do the following:
* Allow 124.4.* to telnet into our system via port 23.
* Deny all others on port 23.

I’ve found DEVINIT1 & 2 Telnet exit programs but they are written in C and we don’t have experienced C programmers in our group.

Any ideas on a exit program here. It doesn’t sound too difficult but is beyond my skill set.

Thanks,

Does anyone know how to prevent a Telnet User Exit Program from affecting Client Access.
I am able to block a user from getting in thru telnet xxx.xx.xxxx from the PC side.
Yet, this same exit program also blocks a person from using client access, which I can not have.

I don’t really understand what my issue is, or, maybe it just isn’t possible to affect the PC telnet command, without affecting the Client Access command.

Bottom line is that I don’t even want my exit program to run, insofar as Client Access is concerned. Only when telnetting in from the PC Telnet Command.

Please advise

I am working on a TELNET exit program that will prevent people from getting in thru the PC RUN Command, whereby they type in telnet (I/P address of the AS400); ie telnet xxx.xx.xxxx.

I recently downloaded the program DEVINIT2 to see if this would work. . Well, I have 2 issues with this program.

a. Whenever I change the MAP QTXTSRC program thru SEU, and key in a specific user as one of the parameters, it does not work. Anyone can still get in thru the PC Run command.

b. No matter what I change in the MAP program thru SEU, it not only affects the PC Run Telnet Command, but, it also affects client access. So, I not only lock a user out of the AS400 thru the PC run command, but, I also lock them out of the AS400 thru their local Client Access. So, they can not get to their AS400 thru client access, and the program is no good to me here.

I am wondering if there is an alternative to the exit program that I am using, or, if someone is familiar with this particular program and can give me some hints as to what I may be doing wrong.

Please advise

I have a simple RPGLE program witht the following parms.

&Usr_Info *Char Lent(44)
&Dev_Info *Char Len(28)
&Conn_Info *Char Len(76)
&Env_Opts *Char Len(1)
&Len_Env Type(*int)
&Alw_Conn *Char Len(1)
&Alw_Auto *char Len(1)

In my RPG program I peform an Except statment to see what the parameters have in them at the time the Exit Program is invoked, since, I can’t figure out how to debug the program.

Anyways, the Usr_Info parm if blank when I perform the execpt, so, I must not be passing the parameters into the program correctly.

Does anyone have any ideas as to what I may be doing wrong. Not really sure how to define the Alw_Env Paramter in the RPGLE program either ?

Thanks

Nick
