Hello,
FTP connection is kind of slow on my server running Redhat 3.0
When I tried to view the NIC speed using mii-tool and ethtool, they both show different speeds. mii-tool shows 100Mbps and ethtool shows 1000Mbps
# mii-tool -v eth0
eth0: negotiated 100baseTx-FD, link ok
product info: vendor 00:aa:00, model 56 rev 0
basic mode: autonegotiation enabled
basic status: autonegotiation complete, link ok
capabilities: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control
link partner: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD
# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]

Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: umbg

Current message level: 0x00000007 (7)
Link detected: yes
dmesg shows "e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex"
which is the correct setting? is it 100 or 1000 Mbps ?
what could be the cause for a slow FTP connection. All other servers are fine except this.
I appreciate your suggestions and help
Thx in advance
TG
