Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting
Dec 16, 2010Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:
Ubuntu Networking :: Assign An IPv6 Address To Separate Users?
Apr 15, 2011I have an Ubuntu 10.04 server/router with IPv6 internet connectivity (I have an internet routable /64 subnet). Since I have this abundance of IPv6 addresses I wanted to try and assign v6 addresses to specific users on the local system. I've been looking at ip6tables with packet mangling but I don't seem to be able to find out how to do this or if this is even possible.
Current configuration: eth0: Local network, has the /64 IPv6 public range active and the IPv4 LAN range. tun0: 6in4 tunnel with a ISP assigned public v6 address. eth1: Standard IPv4 internet connection.
All users on my system use the v6 address configured on tun0. I want to force them to use the /64 range which is configured on eth0. If I can force users to use a specific v6 address, I'll configure more then one v6 address on this interface based on the users userID on the system.
Fedora Networking :: Block Certain Sites For Exception IP List Users?
Nov 3, 2009I have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.

Dec 11, 2009I use getaddrinfo to get the ip address of the server, it works well on other 3 machines, but always get local address 127.0.0.1 on an 64 bit linux machine. Therefore, other remote clients can not connect to the socket server because the server binds local address l27.0.0.1.
I have also tried pass 0.0.0.0 to getaddrinfo, now the server bind on 0.0.0.0(all available interface). But now I can not print the correct network address of the server, as it is always 0.0.0.0 which is provided by getsockname.
I do not know how to get the network address of the server, rather than the local address.

Networking :: Get A List Of IP Addresses Currently On The Network?
Dec 13, 2008I am using DHCP on my home network. There could be as many as 5 computers logged in at any given time. Their IP addresses change depending on the sequence they log in.I want to be able to connect to them from any of them (some wired, some wireless) and share files by issuing a mount command for the appropriate shared drive.My question is how to get the IP of each computer when I only know the names of the computers. Pinging the computer name succeeds, but it does not give the IP.In other words I am looking for a Linux command that will come back with a list of IP's with their corresponding computer names so I can issue the right mount command. I would like to issue this command from a Linux terminal, but would also be happy to issue it from a Windows XP station.

May 27, 2011I have been trying to wirelessly connect to my network for weeks now. My netgear dongle is fully working. I have installed the driver using ndiswrapper. I can see my network and signal is excellent; everything is working perfectly. When I try to connect it thinks about it but never connects. The password is fine; it works great with other computers. decided to have a go with wicd, so got rid of the Gnome network manager and installed wicd. Adaptor and wicd appear to be working brilliantly EXCEPT I cannot connect. wicd tells me its a bad password. Password fine because it works brilliantly with every other device I connect to my network. If I remove security from network, it tells me it cannot get address, even though it sailed passed that with no problem when there was security. I have searched the internet for a solution to this problem time and time again. Lots of people seem to be having this problem, but no one knows the solution. Is there a solution? It happens with both Ubuntu 10.04 LTS v1 v2 and Ubuntu 11.04. What the heck is going on. This happens with WPA WEP and anything else I try to use

Ubuntu Networking :: No Network Icon In Panel - Switch Users
Nov 8, 2010Have a strange problem with the network icon on my laptop.
I have two users (me & my wife). We often log in and use switch users so we're both logged in at the same time.
Whoever logs in first will get the network manager icon in the top panel, and whoever logs in second won't get the icon.
The second user does get a message (growl notification?) saying the wireless network <whatever> is now connected & it is indeed connected.
It's a bit annoying, as if I log in second, I can't chnage my wireless network to the other one we have, I'm stuck using whichever one my wife selected.

View 1 Replies View RelatedUbuntu Networking :: Cannot Obtain IP Address / Disabling Network Manager In Preferences
Mar 13, 2010The IP address acquisition problem I reported earlier has returned, and I am stymied. To recap: Ubuntu 9.10 would not obtain an IP address via a wired Ethernet connection. I resolved the problem at the time by configuring eth0 in /etc/network/interfaces:
Code:
auto eth0
iface eth0 inet dhcp
and disabling Network Manager in Preferences > Startup Applications.After a powering down the PC today, the problem has returned. It appears that dhclient cannot obtain an IP address. This is true whether I am connected to the router (a Linksys WRT54G running Tomato), or directly to the DSL modem. When my usually wireless Ubuntu 9.10 laptop is wired to the router, it obtains an address almost instantly. I have made no changes to the network configuration since January. I have tried to keep current on Ubuntu updates.
Code:
jgb@alienware:~$ ifconfig eth0

Ubuntu Networking :: Change Ip Address Of Second Internet Sharing Network Card?
Sep 2, 2010I have a second network card in my ubuntu desktop that I have sharing my internet connection with a wireless router. I have set the router to a static ip address within the network cards range. But, every time I restart the computer, the network card uses a different ip address. One time it will be 10.42.43.1, the next time it will be 10.42.46.1, ect. This makes me have to hard reset my router every time it does this. How can I set the network card to use the same ip address all the time?

View 3 Replies View RelatedNetworking :: Individually Address Hosts In Private Network From The Outside
May 24, 2011The facts are as follows:
1. I have at work a regular LAN with many PCs, each with a DNS-registered public IP. Therefore I am able to address each of these PCs by their fully-qualified names and, for instance, initiate ssh sessions to any of these computers just by typing "ssh <name_of_machine>" from a terminal.
2. Within the aforementioned LAN I have just created a private network with some clients, which access the LAN through a router (a D-link DIR-825). We have created this private network for many reasons, but most importantly because we need to guarantee that the hosts in this network will remain networked among them even if the LAN goes down for any reason (which unfortunately happens often). But we still need to have access to the hosts in the private network from the LAN.
3. I am able to define port forwarding rules in the router in order to access certain services on the private network's clients. For example. I am able to access (by ssh) hosts "H1" and "H2" on the private network from a client on the LAN by defining rules for forwarding ports "P1" and "P2" on the router's public IP to TCP port 22 on the private IPs of "H1" and "H2", respectively. Then I would access each of these hosts from the LAN by using:
>ssh -p P1 [ip.address.of.router] (for accessing H1) and >ssh -p P2 [ip.address.of.router] (for accessing H2)
4. The problem with the port forwarding approach is that it is not easily scalable. For instance, If I wanted to enable ssh access to each host in the private network, I would have to define a port forwarding rule for each machine, and then REMEMBER all these port rules when initiating a ssh session from the LAN in order to point to the right host. And the problem gets worse when considering more services in addition to ssh.
5. The ideal solution would be to be have a means for addressing each host in the private network individually, in much the same way in which I address the hosts in the LAN (which have DNS-registered names). For instance, in order to access hosts H1 and H2 as in the previous example, i would like to be able to just type
>ssh [name_of_host_H1] (for accessing H1) and >ssh [name_of_host_H2] (for accessing H2)
The bottom line:
I guess I can say that what I need is some kind of combined DNS-ing and routing that allows me to communicate with the hosts in the private network from outside of it in a transparent way.
The question is: what are any possible solutions for accomplishing this? I have searched the web and found stuff about things like VPNs, reverse-proxies and NAT servers, but I really can't understand if any of these could serve to solve my problem (BTW, isn't my router doing some sort of NAT-ing already? could I just add some DNS-ing in some way?)
