I just recently received my EtherTalk board for my Mac II and finally
got my A/UX machine up on the network. When things work, everything
seems to work well (ftp, telnet, nfs, sendmail), but frequently I have
a problem which causes the network to come down.
The problem sometimes happens as often as every half hour, or
sometimes not for several hours. When the network goes down it is
accompanied by console messages. I have seen three different (but
similar) sets of console messages:
Receive overflow warning
ku_fastsend: if_output failed: error=70, sentpck=0, am=0
or
ae6_intr: Receive overflow warning
<hostname>: Network is down
or
ae0: overflow NIC reset failed
ae6_intr: Receive overflow warning
As soon as these console messages appear, the network is down and
subsequent telnet's, ftp's, etc, fail with "Network is down". The
only way I can get everything working again is to do
"/etc/ifconfig ae0 up".
Does anyone have any idea what is going on? I don't yet have the
networking manual from APDA. In case it matters I'm on a class B
network and my broadcast address is n.m.255.255.
Any help would be greatly appreciated.
