Dialer remote-name - what is it for?

[cjdoidge]

Hello there,

ISDN dial-up. One of Dialer's interfaces.

I don't understand one thing - what "dialer remote-name remotename" is used for ?

I understand that when router dials out for authentication it either uses its hostname or "ppp chap hostname HOSTNAME"

So what does dialer remote-name stand for ? Is it like expected remote host name or what?

Thanks,

Alex

It is exactly that, the expected CHAP name of the remote side. It is used, for example, if you are authenticating in both directions, which is often the case. Many PPP features, and authentication in particular) operate in each direction independently (and independently of who made the call in the first place).

So ... when A calls B, A authenticates with B using its own CHAP name ("A"), and B authenticates independently with A, using its CHAP name ("B").

Hi Alex,

First of all see the follwoing link about PPP CHAP Authentication :

http://www.cisco.com/en/US/tech/tk713/tk507/technologies_tech_note09186a00800b4131.shtml

then see :

http://www.cisco.com/warp/public/793/access_dial/ddr_dialer_profile.html#conf

that's an example of DDR and CHAP authentication through BRI interfaces.

be aware at CHAP authentication when two hosts are going to connect together, they should have same password at each side, it means password must be same on both routers.

so when you define dialer remote-name at dialing out interface, it tells to router to use appropriate password to challenge to remote host, also at the remote router (dialing in), the dialer remote-name specify the dialer profile to use.

Hope this helps.
