First, make sure the HiPerArc software is updated to at least Version 4.2.32. To prevent simultaneous logins, you need to issue the following command on the NAS machine:

set pbus reported_port_density 256

Also, look at the checkrad program on the RADIUS server and comment out the following line, found under the subroutine sub_usrhiper:

($login) = /^.*\"([^"]+)".*$/;

Ascend equipment

You may see the following error entry in your log files:

This problem usually occurs with MAX 4048 machines. To correct this, make sure that the NAS is correctly set up as a max40xx in the naslist file and double-check that Finger is enabled on the NAS machine. It can be found ...
