Re: (ASCEND) Establishing P75 connection to ISP takes long time
So I am guessing that you are the ISP that Peter is having a problem with?
So you say that the login times get very very high, until you reboot the
MAX and then the login times get back down to a second or so? That's bad,
but I am sure you know that already.
Well, first of all if you could include every detail you can think of in an
email back to the list or to me privately, that would help. As in what ver
of RADIUS are you running? What platform are you running it on. How long
does it take the MAX until it must be rebooted? When this slow down occurs,
does it affect all users? Does it affect a local connection profile user,
when the slow down occurs? Do you see this problem occur when the box is
heavily under load, or has been heavily utilized. Do you have many other
devices using the same RADIUS server, do they see slow downs at the same
time the MAX does, or is it just this *one* MAX?... etc etc...
thanks
