Debian Configuration :: Network Refuses To Connect

Aug 21, 2015

I installed a fresh Debian Desktop without the LAN cable connected. After that I got message when I put the cable in:

Code: Select allNetwork Interface
Connection New Wired Connection failed

I have tried to re-install everything once again with the cable in, but during the Debian installation there was no network detected.

However, I proceeded and re-installed Debian. But the problem persists. It continues to re-connect and than disconnect. There is a symbol showing re-connection. The network eth0 is visible to the machine.

I booted Mint Live disc and the same happens there.

Debian Configuration :: Network - Cannot Connect To Any Other Websites And Apt Will Not Connect To Any Servers

Feb 18, 2011

I am using Squeeze and all appears OK at first... I have a DHCP lease, PING to router works, apache servering fine in and outside the network, Epiphany seems to connects to default debian.org only, BUT I cannot connect to any other websites and apt will not connect to any servers. I installed once, tried to fix problem, gave up and reinstalled and still have the same problem.

I unistalled Network Manager thinking that was the problem, but still the same issue. Is there a default firewall blocking certain connections or am I missing something I'm supposed to know about? I installed some non-free firmware in the beginning of install and all worked... and I connected fine when downloading packages during install.

Ubuntu :: System Refuses To Connect To The Network / Internet

Jun 1, 2010

So I've recently installed Kubuntu 10.04, and after the first and second runs, the system refuses to connect to the network/internet. I'm not sure why this is, or how to fix it. It shows up in ifconfig, but other than that I'm at a loss. The Knetworkmanager applet says "Disabled" when I hover over it, and no connection can be made to the internet (apt, Firefox). I'm running x86, with a Biostar T5XE mainboard (Realtek RTL8168D/8111D network chipset). The logs don't seem to indicate a problem, though I could be wrong. The connection is known good: it connected before, but it won't now.

Debian Configuration :: Cannot Connect To Anything On The Local Network?

Dec 24, 2010

Two nights ago I decided to switch from testing to unstable. Since then I am able to connect to the internet, but not to anything on my local network. I am unable to ping this computer from another one on the network. This computer is connected through wireless. I thought that something might have changed with iptables that was blockinghe localnetwork. I tried to "flush the iptables settings with "iptables -F". Since that didn't work I uninstalled iptables (which didn't work and I reinstalled iptables). In my browser I tried to connect to my router and that doesn't work either.I connect to this computer daily through ssh and connect to a NAS. Without ssh and my NAS I feel kinda lost

Debian Configuration :: Can't Connect To WPA2 Network

Aug 31, 2011

I have a laptop (running Arch Linux) and a desktop. Until recently my desktop computer ran Arch but I'm taking Debian for a spin now. At my home there is a wireless network with WPA2 encoding. I use the wicd gui to connect to this. I assume, that since I can see the SSID in the wicd window, all drivers are correctly installed and functioning. On my Arch computer, wicd reports this SSID as having WPA2 encoding, but on the Debian computer, it shows up as WEP. Even when I choose the correct encryption thing, WPA2 (preshared key), and put the correct password in, I can't get a connection up.

Debian Configuration :: Cannot Connect To Certain WLAN With Network-manager

Jul 23, 2015

Since a recent update on Stretch, I have been unable to use the network-manager to connect to my home wireless network on my laptop. It was working fine before. I did not change any settings on the WLAN router. I can still connect to other wireless networks at work and university, just not this particular one at home. All other non-Debian devices in my household are still able to connect just fine.While figuring this out, I have tried connecting manualy with ifup but I don't really know how that works. Right now there is only the loopback entry in /etc/network/interfaces.

Below is the output of syslog, when gnomes network-manager is trying to connect, but fails.
Code: Select allJul 19 20:01:57 debian NetworkManager[6705]: <info>  (wlan0): Activation: starting connection 'Affenbande'

Debian Configuration :: Refuses Port Connections - VNC

Sep 29, 2010

I'm trying to setup VNC on our debian server so the boss can remotely do admin stuff from anywhere in the world. the first step is getting it working from anywhere in the room, though. And I can't even seem to get that far.

So far I have a VNC server setup, although not without problems. I downloaded and installed vnc from the vnc site, that wouldn't work because trying to start a vnc server gave this error: "error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory"

There are lots of results on google for this error, and the solution everywhere seems to be the same. to install the package: libstdc++2.10-glibc2.2

However, trying to install this package in debian fails. both using apt-get and trying to manually download it from packages.debian.org it just doesn't seem to exist.

I've tried tightvnc from the official repositories and it gives the same error, too.

The way I got around that eventually, thanks to another tutorial, was to install the package vnc4server. then run vnc4passwd to create a password. and after that vncserver works fine, or seems to. Creates display 1.

Now, when I'm trying to connect to hostname:1 from another computer in the LAN. It gives error 10061, connection refused. I installed the debian and I don't recall setting it up to refuse connections on port 1. Is there anything I should check or change to allow the connection, or any log file in debian to check and see what's going wrong?

I'm also trying connecting internally via client on the debian machine, but I can't runvncviewer. I get the same missing shared library error as before. I guess I just worked around, not solved it.

I also can't access it with the java viewer. Trying to connect on port 5801 either from the server itself, or from another one on the lan, tells me it's refusing the connection.

To be clear, I'm certain that the vnc server is started. We have working DNS, and trying to connect directly to the internal IP:1 doesn't work either.

Debian Configuration :: Use A Network Bridge To Connect Virtual Machine?

Jul 26, 2011

I'm attempting to use a network bridge to connect my virtual machine, like so:

[Code]...

The issue is that when I type the following command, I get the further following horrible error message that doesn't seem to really point me to anywhere and I can't seem to find any relevant information to my problem on the web:

root@darkstacks:~# qemu-system-i386 -hda test.img -m 128 -curses -net nic -net tap,ifname=tap0 warning: could not configure /dev/net/tun: no virtual network emulation

Does anyone have any idea what I need to do here? My processor does not have the vmx flag, as it's a 2.4GHz P4. I don't know if that might have something to do with it.

Debian Configuration :: Connect Jessie To Windows Share - Network And CIFS

Dec 4, 2015

I try to connect my Debian Jessie to my Windows share

This is what I have done:

-> 1 - create an .smbcredentials file located in my /home directory (with account / password and domain)
-> 2 - implement /etc/fstab with information like that :
//192.168.x.x/Animes/media/Animes cifs uid=toto,dir_mode=0777,file_mode=0777,credentials=/home/.smbcredentials,iocharset=utf800

and when I try to go on my windows share, I have this message:

An error occurred while accessing 'Home', the system responded: mount: only root can mount //192.168.x.x/Audio-Video-01 on /media/Audio-Video-01

I think about one thing, if uid=toto is different in fstab than my current debian account session name, it is possible the problem came because of that?

(fstab, uid=toto and current session titi)

Debian Configuration :: No Longer Connect To The Wireless Network After Squeeze Upgrade

Apr 17, 2011

I upgraded from lenny to squeeze on a notebook and I can no longer connect to the wireless network. The computer is an LG notebook and the network card is ralink rt2860. I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked

$ lspci|grep Network
08:00.0 Network controller: RaLink RT2860

Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.

Networking :: Refuses To Connect To The BT Homehub

May 30, 2011

I have linux mint 10 and a bt homwhub 2.0. The wifi dongle that I use is a BT Voyager 1055. Before a week ago I could connect to my bt homehub via linux mint and the bt voyager easily and quickly. But now, however, it seems that Linux Mint refuses to connect to the BT Homehub, the BT Voyager dongle seems to be working because it's green light is on. The Bt homehub is fine because our other windows pc's connect fine (I'm on my windows XP laptop now) but linux will not. On linux it recognises that the dongle is plugged it and picks up various WIFI connections including my BT Homehub, but when I try to connect it to the internet via The homehub, it will not, it try to connect for a minute or so and then a little message comes up saying 'wirless network disconected' any one now what to do ?

Ubuntu Networking :: 10.10 Refuses To Connect To Facebook?

Jan 25, 2011

I recently removed Windows from a family member's laptop (Gateway NV52) and installed Ubuntu on it. I started out with Ubuntu 10.04 since it was an LTS. She's been very happy with it until a few days ago when it started acting up and refused to load almost any site she frequently visited. I decided to back up her data and do a fresh install of Ubuntu 10.10 (64bit) which is what I use. It installed fine, wireless works seamlessly as well.

However, Facebook refuses to load on any web browser (chrome, firefox, minefield, midori, etc.). It's only Facebook as well. The login page will appear but it will absolutely not login. I've tried it with several different accounts and it just flat out refuses.y other site loads fine and fast, and logs in fine, but facebook just doesn't seem to load.I really do not want to have to move her back to windows 7 as she's prone to viruses and Ubuntu is just flat out awesome at virtually everything, but for her, social networking is her primary way of connecting to friends and it's critical for her to have access to that site. It's really her make or break feature, and if Ubuntu can't do it then she doesn't want anything to do with it.

I've looked everywhere for a solution to this. I've tried changing DNS servers, disabling and re-enabling the wifi, clearing the cache and cookies, even down to resetting the router we use, all to no avail. The site loads fine on every other PC regardless of the OS, and I've run out of places to look.My experience with the Ubuntu community has been top notch so far, and I'm not shy of any terminal work that may be needed, nor am I shy of fiddling with anything.

Ubuntu Networking :: Belkin Wireless Refuses To Connect?

Jun 15, 2010

I was dual booting with XP and Jackalope using a Belkin N wireless USB. The install on Jackalope was simple, a plug and play type situation, plugged it in and it worked. A few days ago though, i wiped the whole computer and installed Lynx. To my dismay, even though Lynx sees the wireless, sees the available signals, lets me input my password... it fails to connect. It just spins and spins and eventually asks for my password again...

I'm still pretty new to Ubuntu, and Linux in general. I updated, and pretty sure i retrieved 3rd party drivers for the video card properly (using a cable connection), but thats pretty close to where my "expertise" ends.

Fedora :: Evolution Refuses To Connect Localhost IMAP Server

Nov 21, 2010

I have a strange problem with evolution in Fedora 14. I run my own mail servers (Postfix and Dovecot) on localhost. This all worked great in F13 but now evolution refuses to connect to the localhost imap server. If I connect from my laptop (also F14) i.e. not from the localhost all works fine and great with evolution. I deleted all the config and started again to no avail. I also created a new user and logged in with this user and I still get the same so looks not to be user config issue.
evolution --debug=evo.debug.txt returns nothing useful.
Dovecot is listening on localhost as I can telnet to the imap port. Also other imap clients like Thunderbird work fine.

Debian Configuration :: Network Not Work When Use 2 Network Cards

Oct 24, 2010

I'm planning to use Debian as the OS for a firewall machine, which will sit between my internet connection and the rest of my computers. Now my network is all wired, no wireless whatsoever. I'm using the onboard the motherboards cat5 socket which seems to be using the VIA rhine driver and I'm also using a 3com 100MBps card.

I can list the machine spec if you want but it's nothing special, an old Athlon 64 rig with 1gb ram and an OEM motherboard, it all seems to work ok apart from the internet doesn't' seem to work. Lenny seems to detect both cards ok and I even used the net install CD and it managed to download everything using the 3com card.

The strange thing is when I'm in Lenny, I can't seem to connect. I can ping google, but when I try and view a webpage, the browser just sits there with a while screen... Could it be that using 2 network cards is confusing Debian? Right now I've only got the modem hooked up the the 3com card, and nothing connected to the onboard network card.

I have also put it in /etc/init.d/rc.local to get it to load up on startup. This works and I am able to connect using the network manager. The problem is if I disconnect and then try to connect again later, it refuses to connect till I reboot and then it works, till I disconnect again.

Debian Configuration :: How To Connect Wifi From CLI

Jan 7, 2014

I did a netinstall earlier today (latest version, amd64) on my Dell XPS laptop and ended up with a minimal installation because I couldn't connect to the internet. Now I'm trying to get online without a desktop environment.

I have an Intel Centrino 1030, so I downloaded and installed the firmware [URL].... with a usb, then rebooted. My searches have turned up a lot of instructions involving a utility called iwconfig and wpasuppliant, but these are apparently not installed. I don't really know much about it, but my /etc/network/interfaces file looks rather empty:

Code: Select all# The loopback interface
 auto lo
 iface lo inet loopback

Shouldn't there be something like wlan0 there? The network card does show up with lspci

Debian Configuration :: How To Connect /dev/tty.. To IP Port

I need to connect to a serial port server via /dev/tty.. . The serial port IP addresses are the server's IP address with a particular port # (10001, 10002 etc). The way this seems to work is to create a pseudo-tty and somehow link or configure it to point to the serial server's IP/port #'s.
