View 3 RepliesI'd like to have a set up where my Ethernet card has a static IP set up but my WiFi card doesn't.Currently I have a profile for this set up in Network Manager, however on boot up and every time I replug the cable Network Manager chooses the default "auto eth1" profile. I manually have tochoose my own profile for the Ethernet card every time. How can I make it default??I know the workaround would be to use ifup but then I lose the ability to quickly change access points for my WiFi card so that's not a solution for me

At this time there is no security concerns (even though I want to do it right) , because the computer has not even ethernet cable.

I am trying to set up SSH so that I can edit files on a home server (linux). I know this question has been asked many times before, but none of the answers seem to apply to me.
Here's my setup. I have the modem connected to a switch (wired) that connects 2 PCs to the internet (one desktop, one server, both wired).
All of the threads I see that discuss static IPs seem to require that I set up a router. Is this necessary? Can I still transfer files through a switch?
I have a temporary system up with wlan0 and eth2.
I want the eth0 address to be the gateway for accessing the internet on wlan0.
How do I setup static routes?

I'm trying to use the nm-applet tool get a static ip on my wlan. I've created a configuration and set up the IPV4 settings ok but I can't figure out how to stop nm-applet from creating and using the auto wlan configuration. I've tried deleting the auto config but it seems to recreate it when I try to use wireless again. How to make the manual config the default or permanently disable the auto (dhcp) config?

View 7 Replies View RelatedIn 8.04 I can use the network manager app to set a static IP.
In 8.1 the network manager doesn't seem to work. I tried many different permutations of settings and got nowhere. Even though I put in IP subnet and gateway it still does the DHCP config.
So I added lines to my /etc/networking/interfaces file like this:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.0.100
netmask 255.255.255.0
gateway 192.168.0.1
I then either reboot or do this: sudo /etc/init.d/networking restart
This made the network manager icon in the top panel vanish. An ifconfig showed that those settings are in place but DNS doesn't seem to be working. I can ping other hosts on my network by IP but not www.yahoo.com etc.
I even read the man, that's how desperate I got! (a config like the above seems to work on my 8.04 machine except that the auto eth0 appears at the end of the file.)
I didn't see how to set the DNS server(s), unless I was in the wrong man.
I am trying to secure my LAN a little by doing static arp entries. But I am not sure how to go about doing this... I have a gateway, and I have a seperate box that runs dhcpd. I would like to assign every machine an ip and only allow it to use that ip, therefore static dhcp entries, and static arp entries on the gateway.
1. But how do I prevent someone from picking an ip that nobody is using and assigning it manually?
2. I assigned a static arp entry by doing arp -i br0 -s 2.2.2.35 00:1F:E1:CC:2E:46, how do I remove it now? I used arp -d but now it just says:
? (2.2.2.84) at <incomplete> on br0
3. I would also like each machine to have a hostname/dns.. like machinex.local, where I can do forward and reverse dns lookups, how do I config this?
4. I know static arp can be fooled if someone just clones an allow mac.. is there anything else that I could use that is more secure for wired lan?
5. I have my gateway running rflow sending all data to ntop running on my dhcp box.. Ntop is kinda cryptic, is there anything easier to use? or something that is better in features? I would like to see how much bandwidth each local ip is using and possibly what protocols, like ntop already shows.
Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

I'm setting up a home webserver with Ubuntu 10.10 and want to configure the interface to static. I'm using a router, which is setup and working correctly. I have been using linux workstation with dhcp for some time.
I've edited my interfaces file to reflect the parameters for setting static ip, with the exception of 'network'. No matter what I put into this setting, it causes me to loose connectivity to the outside world. I've tried to put my router IP, and my IP set by my provider. What should the 'network' value be?
At this time, my 'interfaces' files only includes the following and has connectivity out to the internet:

I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).
View 13 Replies View RelatedI need static networking to be functional on F14 to try freeipa....the problem I have is I am unable to get eth0 to start. Knowing the software it has to be eth0 or it will likely not work... The guest is in a RHEV6svr environment... So I have disabled NetworkManager and enabled networ and set manula settings in ifcfg-eth0 incl the hware address but eth0 wont start on boot....
next I tried setting a e1000 network card after the hypervisor default didnt work, only to find that this doesnt work either. The MAC addresses are changing as I try and fault find a dead DNS client issue (yet another F14 issue but lets not go there yet, it could be RHEV's "funky" NATing setup)....so I suspect F14 has got its knickers in a twist over the MAC for ETH0....I keep changing it and I suspect it cant keep up.....so I need to disable the automatic function(s), if there is one....
So somewhere down in the code there is probably a line saying eth0= <mac address> but despite greping I cant find that.....or not something that I edit and it then works.... I have tried the gui tools and command line tools and I still have no network..... So what would be a totally CLI process to fix this automated crap? ie stop F14 pointing at the wrong MAC for eth0?

I want my Ubuntu desktop to have a static ip-address, i have altered the interfaces file to the below and also filled the info regarding my wireless network card but still every time I reboot the desktop gets the ip 10.42.43.1, HOW is that possible???
I use a apple time capsule router, I want my desktop to run a apache server thats why I need the static ip. I also want the static ip to be set on the wireless network interface. I have an old laptop with an internal Intel pro 2200 card so there should not be a driver problem.
This i my interfaces config code...
To be on the sure side to get this to work I have configured my router(DHCP) to give my wireless-HWaddress the ip of 10.0.1.15, STILL the ubuntu desktop starts with the false address above.
I wanted to have a static local IP on my server,But on my 192*.168.1.1, there's a place where ic an see all devices, and before, the displayed name was "STASH" and with the update i put, it'S now "--", but i'd like to keep my old one..
View 2 Replies View RelatedI want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4
IP Address: 192.168.1.6 (This is the item I wanted to change and make static)
Broadcast Address: 192.168.1.255
Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections"
3. I selected the wireless tab and then the wireless network I wanted to edit
4. I clicked on the edit button and then I clicked on the IPv4 settings tab.
5. I changed method from Automatic (DHCP) to Manual
[code]....
I decided to take the plunge and change the existing static ip configuration for my home network to a dynamic (DHCP) configuration. The DHCP server in this new network config is my gt701-wg actiontec DSL modem.

Our F14 server is looses access to the network once we set a static IP.The same IP, if used on any other pc works fine.We had the same exact setup in our F10 server also.

I have tried bringing the interface up and down, and have also rebooted. If I change it to DHCP it will display, but this does not really help me.
I've been using slackware for many years. I think I started with Slack 8. I know how to configure the network, I've had this same POS Dell computer for a few years now but the other day I tried to go to a different distro (first mistake) everything worked fine but it was not for me. Once you go slack you never go back! Anyway I had slack on here prior to the change and it all worked fine. I'm running slack 13 and all of a sudden my network is slow as balls! I set it up as I always have so I did some research and tried a few things, nothing worked. So i enabled DHCP and its fine now.. I have a dell xps 420. onboard intel nic. worked fine when i first installed slack 13. Anyone have any clue what to do? I would like my static IP on this machine.

then I can access via ssh by two addresses the one I got from dhcp (10.17.148.223) and the static one (10.17.148.26) I put ifconfig and and 10.17.148.223 appear on eth0 I restart my server and I just can access from 10.17.148.223 I have to put
ifdown eth0
ifup eth0
Again...to access by my static ip, y can access my page by its dns on my server, but I cant access from other computer...so, I guess when my static adress appears on ifconfig I would be able to access my page from other computer...
Using Fedora 10, can anyone tell me how to setup the network scripts to create two network interfaces for vlan x and y. Both interfaces should obtain an ip from dhcp and both interfaces should run over eth0.
