I cannot set a static IP for eth0 in Ubuntu 11.04. I do this: sudo vi /etc/network/interfaces and then edit the file to auto lo iface lo inet loopback auto eth0 iface eth0 inet static
address 172.16.1.39
netmask 255.255.0.0
network 172.16.0.0
gateway 172.16.0.1
and save the file. Then I edit the resolv.conf file by:

If I have a regular 192.168.1.0/24 network, and configure a static NAT rule assigning 173.194.35.104 to 192.168.1.20 - would that be the virtual equivalent of setting up this device directly to the internet with that public IP? How will static NAT affect open ports etc., if I host an ftp on 192.168.1.20 and assign him 173.194.35.104, there will be no need for portforwarding?
Also - will using static NAT, assigning 192.168.1.20 the public ip 173.194.35.104 affect the way other local devices in the 192.168.1.0/24 network communicate with 192.168.1.20, or will it still be the same? Finally, NAT and VPN can be a bit tricky, but will doing a static NAT rule eliminate all these problems or is there anything I need to know here? You may also wonder why I don't just try for myself and see what happens, but that would involve purchasing the additional IP's and a more advanced router as the current one does not support multiple WAN-ip's.
I was at the login screen on my desktop and I tried to hit my samba share from my Ubuntu laptop. Couldn't find it.I logged in, went back to my laptop, oh hey it worked.I have a static IP assigned to my desktop. Is there any reason why this backfired? I'm just trying to find the proper answer for this
View 1 Replies View RelatedI cannot get a static IP to work on Fedora 11. Using Network Manager, I set the IP to 192.168.1.130, the subnet mask to 255.255.255.0 and the gateway to 192.168.1.0 but it doesn't work. I also tried 192.168.1.1 for the gateway, which is what I used in FC7 but still no luck. I verified that these are the settings that I used in FC7, I don't remember ever having a problem before with this.I do remember someone telling me not to use Network Manager in conjunction with Network Configuration... does that make sense? That was for FC9 on my laptop and it was for the wireless so perhaps that doesn't apply here. I did try unchecking the box for Network Manager and using strictly Network Configuration but it still didn't work.

Yes, another newbie question. Just loaded and updated FC 10. Everything works great with dhcp. Tried to setup static ip to learn more about how to set it up and nothing seems to work. I'm connected to DSL via a router when I ifconfig I get:(basic stuff)inet addr: 192.168.1.7 Bcast: 192.168.1.255 Mask: 255.255.255.0

I'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.

Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.

I want to run networking on my laptops in different environment (home, office, airport etc). I found that Netowrk Manager assigns information from DHCP although I requested fixed IP and configured the gateway and DNS. If I reconfigure the DHCP server so that there is no free IP address, the laptop refuses to connect. When I remove the interfaces from the network manager, I get the fixed IP address, /etc/resolv.conf is not overwritten from DHCP but WiFi connection cannot be established, there is no dialog for setting WPA-PSK. The static IP address seems to be taken into account only if the DHCP server is not found. I need the static address at home and in my office because I need the possibility to ssh to my laptop from another computer but I need IP from DHCP possibly authenticating against RADIUS (Eduroam) when travelling somewhere else. Is there an easy way how to achieve it and how to switch profiles easily? And I cannot switch DHCP off because some devices in my LAN cannot work without it.

View 3 Replies View RelatedI'm using an Ubuntu server 10.04 that I set up on an external 2TB USB harddrive. I'm trying to get a static ip on it because I don't have to keep physically going to the computer to find the IP address so I can SSH and configure apache, mediawiki, and all the other cool stuff Ubuntu can do. I can't (aka really don't want to) use an Ethernet b/c its kinda far, but I don't think thats the problem - wifi vs. ethernet. It's connected to a laptop, so it has wifi built-in. I set up some static IP stuff in /etc/network/interfaces as posted here:

Where "*removed*" means that I have taken the text out of this post for security. At the top, I WAS going to do static ethernet, but I decided I wasn't really going to use and and set it back to DHCP (that what the commented part is). My laptop (and all other computers, actually) are on DHCP and for some reason switch between 192.168.2.* and 192.168.1.* because some configuration is messed up in my router (I can't fix it; no permissions). I have a samba and apache server on the server and want full-time access to it without ssh-ing and changing the ip to the 192.168.1 or 192.168.2 networks every time my laptop switches networks, respectively. I can't access the server with my laptop when they're on different "networks".
I'm trying to set my computer up as a server. I've installed LAMP, but now my problem is getting a static ip. I've tried several tutorials, but with each one, I seem to somehow disable my internet connection.
I'm almost positive that this is all over my head, but my aim is for it to not be.
I figured that i would like to have a static ip address so that i could always know what the internal ip address was of my server. But when i make the address static, I am not able to SSH in from a different machine on my network. The network is wireless/wired, through my D-Link router. I can't even ping the server when i give it a static ip. Is there a way that i can have a static ip address and still have it be seen by other machines in my wireless network?
I have had to re-install everytime I need to make changes to my etc/network/interfaces file. Otherwise i am told that permission is denied, even for sudo. Is there a way around this ?
I recently switched to WEP encryption from a functional WPA encryption and I've been having problems since (I need WEP for another device and I understand it's less secure.) I tried updating /etc/network/interfaces for the new network using the information here:
[URL]
interfaces is now:
Code:
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet static

Is there anything wrong with the above? There is a chance I've made matters worse in my frustration... What troubleshooting steps can I take?
I am trying to set up a static ip address. I am using the visual interface. The problem may be that I don't know what they mean by "DNS servers" the linksys says it is 0.0.0.0 but entering that doesn't help. It says "connected" on the "notification area" icon, but I have no internet. I have rebooted the computer and the router.I deleted Auto eth0 and when I added a new connection it is now "Wired connection 1". If I change it to "automatic DHCP" instead of manual, it works fine.What am I missing, I have easily been able to set static IPs on WinXP machines, I would think Ubuntu would be easier.
View 4 Replies View RelatedRecently, I have encountered a problem when setting my network configuration.I want to automatically get an IP address through DHCP at system startup, and this can be done by editing /etc/network/interfaces file, adding
auto eth0
iface eth0 inet dhcp
The problem is that I want to set a static DNS, but DHCP will automatically overwritten /etc/resolv.conf file.
What should I do?
I'm having an issue with a new install of 9.10. I've set the ip address in /etc/network/interfaces and I've also set DNS servers in /etc/resolv.conf.
The issue I am having is that no address resolves, nor can I ping outside of my LAN. I've wanted to avoid using the GUI network setup because it hasn't been saving the information correctly. Here are how the files look code...
I don't know what eth1 is; I only have 1 ethernet connection in that machine, so I'm thinking it may have something to do with that. However if the machine is using eth1 (which has no address) than it follows that I shouldn't be able to locally ssh or vnc into it, right?
how to set up a static IP from Ubuntu... Secondly, on some of the tutorials I read, there was something about changing the DNS server IP adresses. I do know what a DNS server is (Courtesy of www.howstuffworks.com ) but I don't understand why the DNS servers must be changed simply because I chose to use a static IP address.. (My PC connects to the internet via a router.. )
View 7 Replies View RelatedI have followed some instructions to change to a static ip address and have now lost my connection to my router. The mistake I made was not copying the original "interfaces" file before making changes.The file originally had: auto wlan0 iface wlan0 inet (something - I thought it was loopback but didn't work when I added it).
The instruction told me to put:
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
Which I did, using my own ip numbers, except for "broadcast". I didn't add that in because I didn't have a clue what to put there. When it didn't work, I tried putting it back to what I originally had except I can't rememebr that last bit. I added dhcp instead of what I thought it was but this didn't work either.
How can I keep /etc/resolv.conf static ... as in preventing it from being changed by the network manager ... without actually disabling the network manager (so wireless users can get their wireless setup that includes IP address, but leave the resolver configuration as is)?

auto lo

auto seth0
iface seth0 inet static
[code]....
Restart networking:
"sudo /etc/init.d/networking restart"
Everything is fine but 24 hours later the server resets to the DHCP address assigned to it. I have not installed any GUI im just running Ubuntu 10.04 LTS in Hyper V. After it resets to DHCP I log into it using the dhcp address and reset the networking service "sudo /etc/init.d/networking restart". It goes back to the static IP specified in interfaces. I have rebooted several times but every 24 hours it resets.
BTW - Before someone asks about iface seth0 instead of it being iface eth0. It is a Hyper V module running.[URL]

I have 2 Ethernet connections, one (eth0) for the internet which gets set with dhcp, and one (eth1) for my internal network on which I have dhcp3-server running. I set eth1 to use static IP in interfaces, but every time I reset the network, it is fine for a couple of minutes, and switches over do being served by my own dhcp server on the same machine. (the interfaces file clearly says "iface eth1 inet static")
View 7 Replies View RelatedI 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'll be frank. I recently switched to Ubuntu 10.10 to become more familiar with linux as I set up a website, but I'm also an avid user in a private torrent tracker. Coming from windows to linux, I don't know how to properly set up a static IP address from my wirelessly connected laptop. Other walk-throughs for setting up a static IP seem to focus on desktop machines and not a wirelessly connection machine. These walk-throughs also tell me to delete Network manager, which really messes up the ability to find connections for a wireless laptop. I also have two homes I go back and forth with, so I'd simply like the ability to just emit a static IP, and for my main networks to allow me to connect, and upload/download from it easily.
