 |

Am missing something really simple here!  Just rebuilt the box. Ifconfig shows:
| Code: | eth0 Link encap:Ethernet HWaddr 00:01:02:19:95:3C
inet addr:10.22.18.113 Bcast:10.255.255.255 Mask:255.0.0.0

inet addr:10.22.18.108 Bcast:10.22.18.255 Mask:255.0.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

collisions:0 txqueuelen:1000
RX bytes:45355804 (43.2 Mb) TX bytes:51543402 (49.1 Mb)
Interrupt:10 |
But does not show any local loop. I can see the internet and other machines on the lan, but not internals.

try | Code: | | /etc/init.d/local start |
as root. local doesn't show up if the local service isn't running. |

This is the result from netstat -r and I have two nics in the box.
netstat -r:
| Code: | Destination Gateway Genmask Flags MSS Window irtt Iface
10.0.0.0 * 255.0.0.0 U 0 0 0 eth0
default SpeedTouch.cros 0.0.0.0 UG 0 0 0 eth0 |

Sorted it!
But how do I ensure that this happens when the box boots? |

Check the output of rc-update -s
You might just need to:
rc-update add net.lo boot |

| net.lo is already installed. I am worried that when the server boots, it will not find the network. |

Well I booted the server and some items did not come up. But by inssuing the command:
Evertything is now fine. net.lo is already part of the boot runlevel, how do I ensure that this starts up when the server boots? |

If net.lo was one of those items then you're correct.
So which items didn't come up? Gimmie a list! |

These were the ones that did not come up as I remember:
| Code: | spamd
webmin

net.lo was already in the boot list, but this failed to come up. I have to manually issue the command once I had logged in. Any ideas what I should be looking for to put this right? |

Could you post the exact output of
/etc/init.d/net.lo restart
Thanks |

It does show as having started which is the annoying thing. But when I then issued a ifconfig command immediately after the server returned:
| Code: | eth0 Link encap:Ethernet HWaddr 00:01:02:19:95:3C

In fact, having just restarted the "lo" service, this brought down net.lo, and gave the result just above. When in fact I had started "lo" manually last night. I have just had to start "lo" again:

If you're using baselayout-1.12.0 then you're using iproute2 by default if you have it installed.
Try using ifconfig
| Code: | | modules=( "ifconfig" ) |

| iproute2 is not installed. Should I emerge it before I execute the "modules?" |

Really? Wow.
Maybe that's the problem then - try emerging iproute2 and then restart net.lo
If that works, I'll see if I can fix for next release. |

Put this in /etc/conf.d/net
| Code: | | modules=("iproute2") |
And report your baselayout version |

Please post the following files - (remove comments) if you have them installed. You can do this like so
| Code: | | grep '^[ \t]*[^#]' /etc/conf.d/{net,net.lo,net.default} |

/etc/conf.d/net:iface_eth1="10.22.18.104 broadcast 10.22.18.255 netmask 255.255.255.0"

For gods sake, use a recent syntax.
| Code: | config_eth0=( "dhcp" )
config_eth1=( "10.x.x.x broadcast 10.x.x.255 netmask 255.255.255.0" ) |
And is there any point in hiding the IP of your private network?
Here's mine 192.168.0.51/24 - hack me!
Back to the lo probem - what kernel version are you running? |

I'm starting to run out of ideas here.
Add RC_VERBOSE="yes" to /etc/conf.d/net
Then post the output of /etc/init.d/net.lo restart again please |

No change. UL, do we know where the fault lies? It just seems so simple, but all results come back to say that the service is up when clearly it is not.
| Code: | mwf_03sx140 ~ # /etc/init.d/net.lo restart
* Caching service dependencies ...
* Service 'metalog' already provided by 'logger'!;
* Not adding service 'syslog-ng'... [ ok ]
* WARNING: you are stopping a boot service.
* Stopping lo
* Shutting down lo ... [ ok ]
* Starting lo
* Bringing up lo ... [ ok ] |
