Re: Running public DNS server on iSeries

["Raul A. Jager W." <raul@xxxxxxxxxx>]

I did run a public DNS on an AS/400, it worked beutifull, I had no 
problems.  When I set two default routes (using two different ISPs) I 
wanted to set the DNS so it will respond acording to the ISP from wich 
the request came but I had to abandon because I had to buy a windos 
machine to do it.

I hoppe now we have a proper command or a link in the Web Admin, but I 
didn't check yet.
