Static ip, I'm feeling stupid... (Solved)

ebrostig · Last edited by ebrostig on Tue Mar 02, 2004 6:28 pm; edited 1 time in total

I'm trying to configure one of my machines with a static ip in our corp network. I have received the necessary details from our networking people, yet I can't get this to work and it's not like this is the first machine I have configured with a static ip so I must be overlooking something and I need more eyes on this

Here are the details:

It's it plugged into the network? Either via ethernet or wireless? Can any other machine ping IT?

looks good, the gateway is within the netmask youve got...

i assume youve double checked the details youve got?

problem with the net card itself? mobo? cable? hub? kernel settings?...

mhh, the settings themselfs seem to be ok; broadcast/netmask/default gw can play together...

- the switchport which you are connected to is enabled?
- the switchport you are connected to configured for the correct vlan? (if they are in use of course)
- your mac address is known to the network team? (if they use some sort of 'known-mac-filtering'
- the speed/duplex settings of your NIC are correct?
check with mii-tool / ethtool
set if needed to fixed values; auto-neg can give problems very often

Forgot to mention:
There is no problems with the NIC. It works fine if I use dhcp.

The machine has been on the net using dhcp all the time, I just need to change it to a static.

Your broadcast is wrong.

use: 138.1.4.255

iface_eth0="138.1.3.75 broadcast 138.1.4.255 netmask 255.255.252.0"

Cheers.

airflow · Your broadcast is wrong. use: 138.1.4.255

Well, for what it's worth, I did try both broadcasts as I thought it was incorrect too. No difference when I used 138.1.4.255.

as a last resort, yo ucould turn the box off, and try that config in other machine in the same network, if it works, at least you'll know that something else is wrong.

Try plugging it back in DHCP. Get the NIC info from a working setup, ie.. netmask, broadcast, gateway, routing tables. Plug it back in and use the same setup static. I'm no network expert, but for netmask I always use 255.255.255.0 is 255.255.252.0 correct?

As for using another machine, I can't do that. The ip is bound to the MAC adr of the onboard nic.

I've also tried to use the information from a dhcp configured address and compare it to what I have listed above, and it match.

I'm baffled!

Are you able to ping the gateway? Does the output of /sbin/ifconfig shows what you entered in /etc/conf.d/net?

Check to see if the interface is up:

ifconfig eth0

If it is, ensure the interface has an ip address associated with it.

if it isn't, in the list, start it manually.

ifconfig eth0 up

phu, it seems i found someone who has the same problem as i do!

My server is connected to a LAN. I configured it with a static-ip and can reach the Internet... but when i try to reach any machine in the network - i fail... i also can't be reached by another machine...

it seems that is the same problem as ebrostig has!?!
i'd be very happy, if someone finds a solution :?:

Well, the problem is solved.
Thank you everyone who tried to keep my sanity at a somewhat normal level.

Cause of the problem: Networking helldesk had given me a subnet located in a different part of the country. All info correct, physical location incorrect. They gave me a new subnet and now everything is working like a charm!
