zmodem through access server

(I think there may be some hidden dragons in this forum ..)

We are designing a system to provide files download/uploading service

to field user. In the system, a cisco acess server provide dialin service

for the users, once users dialin, they will download/upload file from/to

a backend file server (solaris)behind the acess server through zmodem

protocol .

Now my question is:

is there anyway for cisco box to automatically telnet to the backend file

server once user dialin? Because to using zmodem, a telnet session need to

established between cisco box and file server, but we don't expect user

launch the telnet connection by themselvies. Instead , we need to find out

whether IOS able to be make the telnet session triggered by dialin event.

Re: zmodem through access server is possible using "autocommand telnet x.x.x.x" under the line config in the access server..

So once the dialin users connect at the modem layer, access server will initiate the telnet session automatically to the specified ip address (x.x.x.x and port is specified)..

Initial portion of the link below discuss that

Re: zmodem through access server

thanks for the reply. One more question though:

Does the field user need to input username/password for telnet session?

Or I can configure a static username/password in the cisco box?

Re: zmodem through access server

You can configure the box not to do authentication so that once the modem connection is made (DSR come up), connection will be "autocommand" telneted to that ip address. Need to go thru authentication if telnet server wants it..Tejal
