Hi Joel, Bingo! I had to bring a new radius server online at the same time we switched to the HiPer system (the old one wasn't sending back the response packets to the HiPer) and I forgot to remove the MTU line from the users file. Doh! Thanks for the tip. On Wed, 2003-11-12 at 13:51, Joel - Fox Computers wrote:
The partial-page download you mention sounds like an MTU setting, possibly coming from your RADIUS server. Past experiences like this lead me to believe your old TC rack ignored the information, while the new one will certainly use the setting, and a wrong setting will cause exactly what you are describing.
Check to see if your RADIUS is sending back something like "Framed-MTU=576", which seems to be a "common" setting on some RADIUS servers, but it will really mess up your dial-up users.

Hello,
We recently switched one of our dialing pools from an old Total Control 1000 system (CISCO AS5100 terminal server cards with USR Quad Modem cards running analog) to a HiPer system with digital lines and v90 support, and now we seem to be having a lot of compatibility problems. Even when we've had our end users disable 56K on their modem, some of them have a problem of getting connected but not being able to access the Internet reliably (they get the first few packets of data, then the browser just hangs, waiting for the rest.) I've noticed that this seems to happen mostly with AOpen FM56 modems, but they do seem to work fine on our other TC 1000 units (non-hiper: Dual T1's with 12 digital quad modems running v90)
Does anyone know of any compatibility problems I should be aware of, or is there any suggestions as to a good init string/script to use in the Hiper systems to make them more friendly with non-USR modems?
