[SOLVED] dhclient and NM work static and dhcpcd don't

I need to get a static ip so I can easily get ssh access to my computer, the problem is that I can't seem to be able to connect with the settings I put in. dhcpcd doesn't work, but NetworkManager and dhclient do.

/etc/resolv.conf

# Generated by NetworkManager
nameserver 192.168.1.1

^ Thats what I normally put in anyway

I wouldn't mind setting up the ip with NetworkManager, I just need the static ip

Thanks for any help.

Re: [SOLVED] dhclient and NM work static and dhcpcd don't

Um, what do you want? Do you want to access your PC from another PC on the LAN or from the internet? If it is the former:
dhcpcd and dhclient are DHCP clients to recieve your dynamic IP if you want one. You shouldn't use them if you configured your network to use static IPs. If you do want to use dhcpcd, you would have to set up a DHCP server somewhere, i.e. on that gateway (192.168.1.1) and configure it to always assign the same IP to a NIC with a specific MAC address.
If it is the latter you need to resarch if your ISP uses dynamic or static IPs and if it uses dynamic ones you need to get yourself a Dynamic DNS service (i.e. dyndns.org) and run something like ddclient to update the IP your ISP assigns to you every time it changes.

I want access from another pc on the LAN, before switching to arch linux from suse I had a static ip setup, but I can't seem to get it working now.

EDIT: Wow, I think I just got it a static IP with networkmanager

Re: [SOLVED] dhclient and NM work static and dhcpcd don't

Well, if you want to do that a simple

ifconfig eth0 up
ifconfig eth0 address 192.168.1.99 netmask 255.255.255.0 broadcast 192.168.1.255

Is fine. No need for dhclient or dhcpcd. They have nothing to do with static IPs.
If you want to do this automatically, the settings in /etc/rc.conf are correct. Just start the network daemon /etc/rc.d/network start and it should be fine.

I tried that and for some reason it didn't work, I managed to get it working through networkmanager though

Thanks for your help
