After install, can't get networking in order to do emerg syn

chris_andrew

Hi, all.

At last, i've just managed to install Gentoo on my UltraSparc :-)

When I booted, I got a couple of error messages, but nothing that can't be ironed out.

Unfortunately one of them was to do with networking, so I can't do emerge sync, etc.

eth0 should be set to DHCP, as my computer goes through a router to my ISP.

When I do ifconfig, only my loopback is indicated.

The error on boot is:

Bringing eth0 up via dhcp /sbin/rc : line 109: /sbin/dhcpd no such file or directory.

I would scp my /etc/conf.d/net, so that I could post it, but as I say, the networking is down on the Sun box.

In the /etc/conf.d/net file, all is #'ed out apart from:

iface_eth0="192.............

and further down in the dhcp bit:

iface_eth0="DHCP"

Can anybody help, i'm just so pleased to get it up and running at last.

Cheers,

Chris.

Lookinin,

Thanks for your extremely fast reply. I commented out the surplus if_eth0 line. I then made a note of my /etc/fstab, so that I could remount my partitions.

I've now rebooted, and mounted the partitions, when I try the chroot thing, it all goes wrong. Do I need to mount the partitions with /mnt/gentoo..., like in the install? Is there an easier way to check I have dhcp installed, or to install it. I know once this problem is sorted, it should get better, but I'm struggling at the mo, sorry :-(

.

Thanks,

Chris.

I guess you wouldn't need to emerge dhcpd, since you are not the server.

Just # out the iface_eth0="192.............. and go with the
iface_eth0="dhcp".

If that doesn't work I'd say you check out the dhcp-IP-range of your router
and set everything manually. But don't forget to tell gentoo your gateway.
# out everything except:

Impz,

Cheers, just got your reply. My router automatically allocates IP addresses, too. Would I have to set a gateway? My box is just one of four home computers that hangs off a router to the "outside world"

Thanks,

Chris.

Impz,

Thanks for your advice. Unfortunately, I still get exactly the same Line 109 error!! Damn.

Sorry,

Chris.

Box just rebooting, will try that when it comes back-up. I know little about emerge at the moment, but I guess it will fail to download from the net, due to eth0 being down. I'll let you know....

Glad to help you.

Jup, you have to set the gateway, otherwise your box wouldn't know where to go to find the www
Just make sure you don't double use an IP address.
Set your IP-address to an address the router doesn't allocate to any other computer.

e.g. If

Computer1 has 192.168.1.23
Computer2 has 192.168.1.24
Computer3 has 192.168.1.25
Computer4 has 192.168.1.26

you could set your linux-box's IP-address to any except those four above (e.g. 192.168.1.30).

J-M,

Tried this, with the message:

emerge: There were no ebuilds to satisfy "dhcpd"

Any thoughts?

Thanks,

Chris.

can you tell me the line 109 of your /sbin/rc ?

just do nano -w /sbin/rc , search for the /sbin/dhcpd string and
copy it down.

I'll see what i can do than.

Forgive my oversight. My eyes read what they expected, not what you wrote...I'll let you know :oops:

ahhh dhcpcd that makes some things more clear.

I thought it was looking for a dhcp-daemon. But emerge wants a client.....
Well # out the iface_eth0="dhcp". line and do as i suggested it should work, bc
you don't need the dhcpdc then, bc you set ip-address and stuff manually.

Aaaaaghhh!

Temporary failure in resolution. It tries, but can't download. Can I somehow get it from the Live CD that I installed from (painful)?

Guys,

I have got eth0 to work. Unfortunately, it has the same address as another box on my home network. I'm assuming it didn't get a DHCP address from my router, then.

In my /etc/conf.d/net, the only lines not # out are:

iface_eth0="192.168.0.2 broadcast 192.168.0.255 netmask 255.255.255.0"

and

gateway="eth0/192.168.0.1"

Nearly working, but not quite.

Chris

I have a router that allocates IP-address automatically and I set everything manually.
just # out iface_eth0="dhcp" and i guarantee it will work, bc the computer will not
ask for dhcpcd anymore.
At least it works with my two linux boxes, and i have three windows pcs
running in our household, too.

Please, Read the Handbook!

Basically, you need only one single line for DHCP.

I'm really sorry. I do know the difference between DHCP and static IP address. I am just having problems with getting them to work with Gentoo. I want a dynamic address from my router, and that's it. How difficult can it be?

I've read the docs, and am still not sure. Sorry i've wasted your time.

Impz, I appreciate that your router automatically allocates addressers, as does mine, but this is what I want it to do, not allocate a static address, as you have.

Thanks,

Chris.

ok....now that this issue is cleared out.

chris_andrew. do you know the ip of your router?
If so please tell me I will then to try and write you a /etc/conf.d/net
configured to fit your machine.

If you can then access the inet you will do emerge dhcpcd and then i can help you
change your configs to fit for dhcp use.

Ahh, I see what you were trying to do, now.

I managed to download dhcpcd, and have adjusted my /etc/conf.d/net fiel to dhcp. This now works correctly and I have booted from scratchand all is ok.

I don't know why this happened, I must have overlooked installing dhcpcd during initial set-up.

Thankyou both for your time.

Now onto a keyboard problem.....
