DHCP question

Rate this Message:
Hello. I just finished installing OpenBSD 4.3. The dhcp setup during
network configuration was fine, meaning, IP address was properly assigned. I went ahead with the default values provided. However, after rebooting post installation, I am getting the following messages that seems to point to a network problem (and of course, no IP address is assigned): <messages> fxp0: warning: SCB timed out (x 3) fxp0: config command timeout DHCPDISCOVER on fxp0 to 255.255.255.255 port 67 interval 1 send_packet: Network is down No DHCPOFFERS received. No working leases in persistent database - sleeping. </messages> Several `intervals` are tried. Dump of some relevant(?) files: #ifconfig lo0: flags-8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33208 groups: lo inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 fxp0: flags-8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33208 lladdr 00:16:76:13:ad:54 media: Ethernet autoselect (100baseTX full-duplex) status: active inet6 fe80::216::76ff::fe13::ad54%fxp0 prefixlen 64 tentative scopeid 0x1 enc0: flags=0<> mtu 1536 #cat /etc/hosts: ::1 localhost.WORKGROUP locahost 127.0.0.1 localhost.WORKGROUP localhost ::1 mercury.WORKGROUP mercury 127.0.0.1 mercury.WORKGROUP mercury #cat /etc/hostname.fxp0: dhcp NONE NONE NONE #cat /etc/resolv.conf lookup file bind # hostname mercury.my.domain #domainname (none) For my internet connection, I have a router that acts as a DHCP server assigning IPs as 192.168.11.x. Why is the OpenBSD box not assigned an IP by this router? Can anyone please let me know how I can get the network up and running on the OpenBSD box? Please let me know in case I have missed out on listing any config files. Thanks. Hari |

I am a novice at this and I have little understanding. I have gone through the man pages for /etc/hosts but I could not figure out what exactly I was doing wrong. What should /etc/hosts read as? And what should the $hostname be? The machine is to be named "mercury". > $sudo ifconfig fxp0 up fxp0: warning: SCB timed out (x3) fxp0: config command timeout Hari |

IIRC, it was 192.168.11.8. The DNS was properly identified as the router (192.168.11.1). I dont think there is a problem with the cabling. (I double checked this with a laptop). Hari |

Apologies. This is my fault. I copied the text incorrectly. #ifconfig lo0: flags-8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33208 groups: lo inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 fxp0: flags-8803<UP,BROADCAST,SIMPLEX,MULTICAST> mtu 1500 Rest is OK. Apologies once again. Hari |

It seems the fxp0 interface fails to do some initializing. This probably results in the interface not being fully enabled/up. I'me not sure what SCB is but i think is related to signaling / irq ? Do you see this also with the bsd.rd kernel? Please look if there are differences between the to in dmesg and ifconfig fxp0 ? Regards Robert -- Microsoft: Where do you want to go today?

The only time out messages listed in dmesg are from fxp0 (dmesg | grep -i time). How do I check the SCB thing with the bsd.rd kernel? Hari |
