 No network connection on new 6.1 install
Author: RichardE

We are an all-freeBSD house, but I still consider myself an amateur.

After installing 6.1 from CD distribution on a fresh 'test' machine, I have no outbound network connection. I can ping host, but when I try to ping beyond I get following error message:

'ping: sendto: Host is down'

Also cannot ping 'test' from other machines on network.

Following ifconfig (on 5.4 on 'ttdbs3' and other machines on network) works fine:

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet 65.70.xxx.xx3 netmask 0xfffffff8 broadcast 65.70.xxx.xx7
ether 00:50:22:88:82:84
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet 127.0.0.1 netmask 0xff000000

New ifconfig (on 'test'):

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet6 fe80::250:fcff:fe3d:3b1b%rl0 prefixlen 64 scopeid 0x1
inet 65.70.2xxx.xx4 netmask 0xfffffff8 broadcast 65.70.xxx.xx7
ether 00:50:fc:3d:3b:1b
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
inet 127.0.0.1 netmask 0xff000000

Do the inet6 entries matter (I thought I had opted out of inet6 on install)?
If so, how do I get rid of them?

I opted for no firewall. But with the inet6 entries in ifconfig, could I also have firewall entries that are preventing getting in or out? If so, how do I find and quench them?

netstat -rn:

Routing tables (on test)

(Plus a whole bunch of lines for Internet6)

127.0.0.1 127.0.0.1 UH 0 1360 lo0 27.

To me it looks like 'ttdbs3' can see the NICs on the other machines (hence the MAC addresses), but 'test' cannot (hence no MAC addresses and no ip addresses other than the gateway, which I gave it as 'defaultrouter' in 'rc.conf').

rc.conf (on test)
gateway_enable="YES"
hostname="test.xxxxxxxxxx.com"
ifconfig_rl0="65.70.xxx.xx4 netmask 0xfffffff8 broadcast 65.70.xxx.xx7"
defaultrouter="65.70.xxx.xx6"
inetd_enable="YES"
keyrate="fast"
linux_enable="YES"
moused_enable="YES"
nfs_client_enable="YES"
nfs_server_enable="YES"
rpcbind_enable="YES"
saver="logo"
usbd_enable="YES"
apache2_enable="YES"
mysql_enable="YES"
postgresql_enable="YES"

rc.conf (on 'ttdbs3')
gateway_enable="YES"
hostname="ttdbs3.xxxxxxxxxx.com"
ifconfig_rl0="65.70.xxx.xx3 netmask 0xfffffff8 broadcast 65.70.xxx.xx7"
defaultrouter="65.70.xxx.xx6"
inetd_enable="YES"
keyrate="fast"
linux_enable="YES"
moused_enable="YES"
nfs_client_enable="YES"
nfs_server_enable="YES"
rpcbind_enable="YES"
saver="logo"
usbd_enable="YES"
apache2_enable="YES"
mysql_enable="YES"
postgresql_enable="YES"

Any suggestions?

Thanks
