Hello, in f11 I had a line into /etc/rc.d/rc.local to force speed/duplex/autoneg: /sbin/ethtool -s eth0 speed 100 duplex full autoneg off >> /tmp/ethtool.log 2>&1 In F12 I see that this setting is not maintained. After I log in in Gnome I see that: [root@tekkaman ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP ] 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: 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 The log file has timestamp of my boot time, so that I know it was actually executed. If I run it manually it succeeds and I get now: Advertised link modes: Not reported Advertised auto-negotiation: No Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off Supports Wake-on: g Wake-on: d Current message level: 0x000000ff (255) Link detected: yes but after some minutes I get again: 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 So there is something external that manage this kind of changes. Some questions: - network guys say me that switch port is fixed at 100/full (it is a gigabit ethernet) so, if this is true, even in autoneg there is an error in getting settings - what is the component that changes the settings? I walked through NM applet to edit connections but I don't see any parameter....

So I have many link down messages and (apparently) renegotiation tthat then gives 100/half Any suggestions??? BTW I have libvirtd started but no vm created Thanks in advance, Gianluca -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
