Hi Andy,
Weirdest problem I've ever seen. Can;t make head or tail of it.
Now that they ignore the firewall I stil get the same result:
server A (neptune)-switch-server B(opal)
If I ping from neptune to opal I get dots appearing on the "ping -f"
command. If I ping from opal to neptune I never get any dots appear.
Which setting do I take seriously:
ethtool:
ethtool eth2
Settings for eth2:
Supported ports: [ MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Half 1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Half
Port: Twisted Pair
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x000000ff (255)
Link detected: yes
or mii-tool:
mii-tool eth2
eth2: no autonegotiation, 100baseTx-HD, link ok
ethtool says HD the other says FD, which ones right.
When copying files to and from it I get around 9Mb/s, which seems good
for me, what do you think?
Thanks
Dan
