Someone suggested changing the duplex settings on the other side, I know
it's running full duplex on DragonFlyBSD, but.. I don't know how to even
find out linux side. I'll have to research that I guess.
ethtool eth0 (or eth1, or whatever it is)


mii-tool (no args)

ethtool will plop out a lot of data, while mii-tool is pretty terse, but
both will specify speed and duplex.

Much thanks!

Well.. I don't know if I should be too thankful.. was hoping they'd be set differently.

Apparently, they're both set to full duplex:


ifconfig xl0
inet netmask 0xffffff00 broadcast
inet6 fe80::204:76ff:fe38:7274%xl0 prefixlen 64 scopeid 0x1 ether 00:04:76:38:72:74
media: Ethernet 100baseTX <full-duplex>
status: active

It doesn't say the speed, but can I assume 100baseTX means it's 100Mb/s ?

Linux: root@pong# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 24 Transceiver: internal Auto-negotiation: on Current message level: 0x00000001 (1) Link detected: yes

Duplex: Full .. I assume that is full duplex, so that can't be it.

I'll try to get boot -v if I can, not quite sure how to go about doing that.

I guess I've had fairly good luck with networking because on the whole, it
usually has just "worked" for me.

I just joined the list yesterday, so I don't know if this was already covered.

Have you tried netstat commands to help?

netstat -rn to view routing table.
netstat -I intname 1 to view per second ether stats.
