But still the secondary has to timeout for 3 seconds. The ARC is not making sense on how it is doing the selection. The primary radius server has no eth errors: eth0 Link encap:Ethernet HWaddr 00:40:63:C5:41:E3 inet addr:207.12.240.9 Bcast:207.12.240.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:17350161 errors:0 dropped:0 overruns:0 frame:0 TX packets:10112143 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:2724138195 (2597.9 Mb) TX bytes:2004015793 (1911.1 Mb) Interrupt:15 Base address:0xec00 and the mii-tool has show that the NIC (a via-rhine card) has not renegotiated or dropped the link.

Is there a syslog facility that will record authentication server switches? -- Paul Farber Farber Technology farber@admin.f-tech.net Ph 570-628-5303 Fax 570-628-5545 On Thu, 17 Apr 2003, Joel - Fox Computers wrote:
Yes, sorta - actually the secondary doesn't have to "fail" - that's not the qualification - if it switches to the secondary, and then at some point later it takes more than 3 seconds for the secondary to respond, then the TC tries the primary - if it gets a response from the primary, the primary becomes the active RADIUS server.
YOu said yourself that you have higher-latency between the TC and the secondary - so it makes sense that should it switch to the secondary, it will probably switch back to the primary in a short time.

Then you are saying the secondary has to fail before the primary is tried again?
So then both my primary AND secondary are failing... I find that hard to believe. Logs show that the daemons are not stopping or restarting.
