Solaris 9 network not connecting until i unplug and replug network cable

Post by czep.. » Wed, 14 Sep 2005 03:18:17



Hi,

I'm running solaris 9 on an Ultra60 with a built in ethernet adapter
and 3 PCI Sun GigaSwift Ethernet UTP Adapters.

Each network card is on a different network. When I boot the system, I
cannot communicate on one of the PCI cards until I unplug the ethernet
cable, then plug it back in and wait about 5 seconds. Any idea what
this might be?

Sounds like it might be a switch problem of some sort.

1. OpenBSD 2.9: can't see network until I unplug/re-plug the network cable

Hi all,

I just upgraded a few machines to OpenBSD 2.9 (from OpenBSD 2.7).  Now, on
my old Pentium, it can't see the network until I unplug/wait a few
seconds/re-plug the network cable.  It's a generic 10/100 card (info from
dmesg below).  It was working fine in OpenBSD 2.7... doh.

When I say "can't see the network", everything seems ok from ifconfig etc,
but I can't talk to anything on my local LAN, and nothing on the LAN can
talk to me.  When I unplug the cable, wait, and re-plug it in, everything
sees everything.  So I'm guessing that something with the media autoselect
might be funky?  I've attached my hostname.dc0, maybe it's bad?  Since this
was an upgrade, this is left over from OpenBSD 2.7, did something change
perhaps?

When I do a ping from my old Pentium before unplugging, I can see the light
on my hub blinking, so I know it's doing something... maybe it's ignoring
the incoming responses?  Got me...

From dmesg:
-------------
dc0 at pci0 dev 9 function 0 "Lite-On PNIC" rev 0x20: irq 10 address
00:a0:cc:5f:7b:47
bmtphy0 at dc0 phy 1: BCM5201 10/100 media interface, rev. 2

From hostname.dc0:
-------------
inet 172.16.0.3 255.255.255.0 NONE media autoselect

From ifconfig -a (same before & after unplugging & plugging it in again)
-------------
dc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: Ethernet autoselect (100baseTX)
