Hi All, I've been using isdn4bsd for some time now and as a general rule it works well. I do however have occasional problems where after a long period of continuous connection the link dies. Curiously enough, IP-layer diagnostics (ping, traceroute) show that the link is down, but isdn-monitor still reports the channels up and running (even with a small amount of traffic flowing). The machine contains two Traverse NetJet-S cards and I'm using userland ppp (obviously with rbch devices). We use three channels in total. Two on the first card out to our ISP and one on the second card to another office. All channels are intended to stay up permanently. Just before the link dies, I get the following messages: Feb 25 06:46:53 zark /kernel: i4b-L1 itjc_dma_rx_intr: RDO (unit=0) dma=508 src=428 Feb 25 06:46:53 zark /kernel: i4b-L1 itjc_dma_rx_intr: RDO (unit=0) dma=520 src=428 Feb 25 06:47:48 zark /kernel: i4b-L2 i4b_rxd_ack: ((N(R)-1)=4) != (UA=5) !!! Feb 25 06:48:58 zark /kernel: i4b-L4 i4b_l4_setup_timeout_fix_unit: 1046116138: ERROR: idletime[60]+earlyhup[5] > unitlength[60]! Feb 25 06:49:07 zark /kernel: i4b-L4 i4b_l4_setup_timeout_fix_unit: 1046116147: ERROR: idletime[60]+earlyhup[5] > unitlength[60]! Any help with pointing me to what is going on would be appreciated! As an aside, I've never really understood the rates configuration properly or how they apply to userland ppp initiated connections. For an always-up connection, what should: ratetype unitlength unitlengthsrc idletime-incoming idletime-outgoing earlyhangup be set to? and what, if anything, should I put in isdnd.rates? Many thanks for any assistance. Matthew. -- Matthew Horoschun Network Administrator CanPrint Communications Pty. Ltd.
