My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.

My Iceweasel is not consistently opening pages. This is new behavior after changing the /etc/network/interfaces file for setting up bridging. The home page is advanced google search. When Iceweasel opens to google, I get a message saying the site is not secure and won't open it. Inputting [URL] ...., it takes about 90 seconds before it opens the site then freezes. If I go to forums.debian.net, the site is fully navigable, if I put anything in the Iceweasel search bar, it freezes.

How do I choose a wireless network to connect to? The Ubuntu 8.10 help tells me to open NetworkManager, but the only thing I can find is 'Network Configuration' in System>Preferences. If I try to run NetworkManager in usr/sbin as a root, nothing happens whatsoever. nm-tool lists several available Access Points for my WiFi antenna.
View 2 Replies View RelatedI have three routers (linksys wrt54gl, ddwrt). I'm trying to use wds bridging, got two of them linked, but not the third. All three routers have the same SSID. I'm using Ubuntu 10.04 netbook remix.
My problem is I need to choose which of these my laptop connects to. Right now it connects to the one router which isn't playing nice with wds. I need it to connect to one of my other routers. I see the other signals using nm-tool, but they don't show in nm-applet. I created a connection in NetworkManager specifying the SSID + mac address of the correct router, but the tray applet doesn't show any options for connecting to manually configured networks, and I can't find any other useful app. I suppose I could rtfm for iwconfig et al, but Ubuntu ought to have an easier way.
I'm surfing along just fine when I select some link in my browser.The status line reports "... waiting for ..." and the browser seems to stall for a long time (minutes). Often, but not every time, I can select the STOP toolbar icon and reload the page. This time things work normally.
I have a similar but different malfunction running Evolution email connected to my hosted IMAP server. I select a message and see "... formatting ..." and then Evolution seems to stall for a long time (minutes). Rarely the stop-reload actions help reading email. Instead,all Evolution windows go dark grey and the entire desktop stalls.[Analysis -- It has the feel of a "network" issue provoking issues within Evolution itself rather than an Evolution-only malfunction.]
Watching the running system with 'htop' and similar, I do not see where some other application or service is sucking all of the available CPU time or such. [Analysis -- It has the feel that either the browser message or the email message were sent into limbo without reaching their intended destination. Stop-reload sends the bits to the right places and so I get results.]
I access the internet through a hotspot with the SSID "OzoneBE.net Open Access". Unfortunately this hotspot is massively overused, and on top of that the signal is weak. There are other hotspots with the same SSID nearby. They have weaker signals, but it's possible they may not be so heavily used, or that I might be able to find a line of sight to one of them, so I would at least like to try connecting to them.
Unfortunately KNetworkManager doesn't give you any way of choosing between these different access points and it automatically selects the most powerful signal, as far as I can tell. RutilT can distinguish between them, but when you try to connect to the one you want, it seems that KNetworkManager intervenes and chooses the alternative with the strongest signal again. However if I kill KNetworkManager, RutilT just won't connect to anything. It fails without explanation.
How can I get proper control over my network management so that I can connect to the hotspot of my choosing, regardless of whether it shares an SSID with another?
When I go to share a folder I do not have the option to select windows networks (SMB). Only the unix service.. I am running ubuntu 10.04

View 3 Replies View RelatedI have a laptop "fura1" with two interfaces, eth0 (Ethernet) and eth1 (wifi), which I assign IPs 192.168.1.10 and 192.168.1.11 respectively. Then a desktop "fura2" with only one interface eth0 (Ethernet). Both are connected to a local network along with other appliances. My doubts arise on how to configure the /etc/hosts file of the desktop "fura2" taking in account that "fura1" has two interfaces, so two IP, but, obviously, only one hostname.
My first attempt for /etc/hosts of "fura2" was:
127.0.0.1localhost
127.0.1.1fura2
192.168.1.10 fura1 fura1.workgroup
192.168.1.11 fura1 fura1.workgroup
192.168.1.102 PDA PDA.workgroup
192.168.1.103 MT MT.workgroup
But it seems to my that assigning two different IPs to the same host is not a good solution. On the other hand, if I give different name to each interface, I will got a host with two hostname (?).
I'm testing some network setups, and bought two dirt-cheap USB network interfaces. My plan was to attach these two to an embedded device (sheevaplug) and mess with firewall setups. However, the two interfaces are absolutely identical; they have the same MAC, and lsusb -v is the same for both, line by line (except for device number, which tells the order the devices are plugged in, I believe?). Also, this is a single usb bus (single port, with a hub).
Now, obviously I can't make much of a firewall setup if I can't tell the interfaces apart. I realize I probably hit a brick wall, but does anyone have thoughts on this?
I have somehow made 2 internet connections on my fedora 10. one is system default, which doesn't work. so I usually login and select from the top panel to the other working one. how to choose it from a terminal? then I can do it from a remote terminal.
View 1 Replies View RelatedI am currently trying to set up two network interfaces in my laptop. The wireless connection wlan0 works fine and it's the one that I use to connect the internet. It's in the range of 192.168.0.x/24 (gateway: 192.168.0.1). The wired interface eth0 is connect to another router (gateway: 10.0.0.13 with IPs in the range of 10.0.0.x/24. The router is set up to work as an AP and the 10.0.0.x network will only be used to control a robot, so no internet access will be required in this network. The problem is that when I have both connections up, I can't access the Internet anymore. I can still ping both routers, I can enter both routers configuration pages but I can't connect to the Internet. If I unplug the network cable, Internet gets accessible again.
I'm still a novice in linux and I can't figure out how to fix this. I don't want to get into static ip for the wireless connection since I'm constantly using the laptop in different places. The objective is to use the 10.0.0.x router to have a development platform for the robot that can be used anywhere without having to reconfigure the robot for a new network, which is a real pain.
In detail, the laptop connects via wireless to the network with intenet (192.168.0.x) and also connects via cable to another wireless router(10.0.0.x). The wireless connection of the second router is used to connect to the robot. Since I can ping both routers when they're both connected, I think it may be something related to the ip routes. I'm using Ubuntu 9.10 with kernel 2.6.31-17-generic

For a very special project, many hardware issues, unusual limitations, etc, I'm turning my ubuntu into an access point (temporarily) by sharing the Internet from one device to another. I found out that with the devices I'm using, this can't be done with the network manager.
I need to get the internet from a device called 'tun0', to my 'wlan0', so it can broadcast it as a very special access point. I've read that there are ways to do this with the terminal.
So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?

I recently upgraded an Ubuntu 8.04 server to 10.04 server. My previous configuration had two network interfaces both routed to the same LAN with the same gateway. This functioned for me so as to support different services on each interface, such as http and smb on one, torrents on another. This routed fine in 8.04 (routing table below). Once I upgraded to 10.04, any packets that traveled beyond the LAN did not return. I checked and there is no local firewall running. Thinking that this was strange I set up a virtual machine and tested it in a different environment at work (and also with a virtual firewall configuration) with the same results.
I also tested several other current operating systems, including Debian 5.04 and Open Solaris 9, all of which routed two interfaces with the same gateway fine. I rolled back from 10.04 to 9.10 and the problem persists, so the change exits also between 8.04 and 9.10. at least identify what is unique to Unbuntu 9.10 and above that is preventing having two interfaces with the same gateway, something that other operating systems do not seem to have trouble with?

I have two interfaces, gprs0 and gprs1, both connected to the Internet from the same HW device, but through two different access points I just read another blog entry with a guy who had two network cards, using one as a back up - I guess this is a little similar, but should be much easier I am guessing - I am just lost Using ifconfig (IP address given by the network) and route to setup the connection,
ifconfig gprs0 10.20.30.40 up
route add default dev gprs0
ping 66.102.7.99 works fine
afterwards

There is data being transmitted and received to device again, I guess the kernel just doesn't know where the incoming data should go without the correct routing tables? Or what exactly is going on?The question I have is how do I configure the device to do the correct routing, using only the ifconfig and route commands? Maybe too trivial for you guys, but I am getting tired of goofing around not knowing what is up and down anymore
DSL modem is a Speedstream 6520 router. All computers work fine via dhcp. I'm trying to setup a small server (print server, ssh & ftp servers). I understand enough of the software part of things to get it going, my problem is setting a static IP on the server box. Every time I set the IP in the /etc/network/interfaces file and reboot, I have no network connection. I can talk to the modem through the browser, but nothing beyond that, not even local computers.
/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.254.202
network 192.168.254.0
netmask 255.255.255.0
gateway 192.168.254.254
ifconfig shows the .202 address, but box can't get to the outside world, and can't ssh into the box from a computer sitting next to it. If I let it dhcp, then I can ssh into it, and have access to the internet. In the modem, I have dmz set for that address. Wan address is static. I can ssh into it if I let it do dhcp, so I know it can work that far. But if I set static ip, I might as well pull the network cable. I've been beating my head on this for over a week, and I'm lost why I can't get it to work. I even changed the dhcp range on the modem, so the .202 is not in that range. There is no dhcp client installed that I can find. I'm using WattOS beta3, which is a light distro based on 9.04. The computer is an old Dell GX150, integrated nic. I have done ifdown and ifup eth0, still no happiness. Doesn't seem like it should be that hard, but I'm stumped. DMZ should let everything pass, so don't need to mess with port forwarding and such. I know it works using dhcp.
