Debian Configuration :: Internet Sharing All The Sudden Stopped?

Mar 7, 2010

I was just doing the normal stuff, working with my raid-setup. Then I needed to reboot. I did that, and then my internet sharing just stopped working?I remember I just did aapt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get autoremove && apt-get cleanbefore booting, and I just dont rembember if that said anyting crucial, but I really dont think so. Anyways, my LAN i working, all my LAN computers speak with each others, and I have internet (...) on the server. But my sharing just doesnt work. This is how I share my internet:

ifconfig eth1 192.168.0.1
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j SNAT --to myip

Ubuntu :: All Of A Sudden Internet Stopped Working

Dec 12, 2010

My brothers computer uses Ubuntu. All of a sudden the internet stopped working. So I did some research online and found a site that looked like it would work because the comments were good. I did what it said by removing the network manager and then i had to re-install it blah blah blah. Long story short his computer is still without internet. I tried to download the network manager on my computer and install it on his computer. I dont think it worked.If anyone could help me find the correct network manager to download for his computer and then help me get internet back onto his computer.

Ubuntu :: Remote Desktop All Of A Sudden Stopped Working

May 31, 2010

I recently setup an ssh tunnel and wrote a script to connect to my Home PC from my laptop no matter where I am.

I have previously tested this on my own network and multiple other networks while I was over at my friends houses, and it worked completely fine.

So just now I decided to use it after about a day or two after not using it and now nothing happens. Normally it prompts me for a password and takes about 5 seconds then I am in.

I'm using openssh, vinagre, and dyndns for the hostname. Here is the script:

Debian Configuration :: Samba: Sharing A Folder With Multiple Groups?

Aug 30, 2010

I have a folder, called Vault, that we want to share only with certain people. Because it will contain confidential information.

I want the unix group trustees to have read-only access I want the unix group administrators (and root) to have read/write access

All other users should have no access.

the implementation I have so far is:
folder owner: root:administrators
folder permissions: 770
section from smb.conf

[Code]....

However, this is not working as expected. It currently works as follows:

Normal user: No access (expected) Trustees member: No access (fail. Trustees should be able to read) Administrators member: Read/write access (expected)

Debian Configuration :: Ssh Randomly Stopped Working On Server?

Mar 15, 2010

I'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1.
I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT STATE SERVICE

25/tcp open smtp
80/tcp open http
110/tcp open pop3

Debian Configuration :: Upgraded To 2.6.32 => Home Gateway Stopped Working

I was running 2.6.26 and I've recently upgraded to 2.6.32-trunk-amd64 along with other packages (mostly dependencies)... which possibly involved the network stack.

After this upgrade my home gateway stopped working and I'm clueless to where the problem may be.

I can see that the iptables are still there when I type:

iptables -t filter -L -v -n -x --line-numbers
iptables -t nat -L -v -n -x --line-numbers

Debian Configuration :: Plex Media Server Suddenly Stopped Working

Jan 27, 2016

My plex media server suddenly stopped working after years of no hassle use. This is the output of cat /proc/version = Linux version 3.2.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.65-1+deb7u2

My problem is similar to this forum thread viewtopic.php?f=5&t=121945 where I can get it to start by running Code: Select all/usr/sbin/start_pms & but it's not my normal server configuration. I added a couple files to it and it seems to work except it doesn't start when I reboot. I have to run that command again.This is the init script I've been running for years...

Code: Select all----
#!/bin/sh
### BEGIN INIT INFO
# Provides:          plexmediaserver
# Required-Start:    $remote_fs $syslog $networking
# Required-Stop:     

[code]....

My Debian skills are lacking to know how to proceed with troubleshooting what could have happened. Everything else seems fine, I just can't seem to get this application to run at startup or get back my old configuration...

Debian Configuration :: Squeeze X Login Stopped Working - Console Works

Mar 30, 2011

I have been using my system for couple of weeks, and normally update software when the icon is displayed on top bar (gnome). Last couple of days there were updates for X, and I am not sure whether that is the cause of my problem. Once bootup, I get the login screen. When enter the password the login screen keep coming back. there is no error about any password issue, or anything. It keeps prompt me to enter the password.

I could login back the following way.

1. ctrl + alt + F1 , and login with the same username/pwd as for X
2.change to root
3.pkill gdm3
4.exit from root to user privilege
5. startx

The system starts X correctly and no login screen is displayed. I could use the system as usual.

The only thing I did custom to my system was upgrading to the latest kernel (2.6.38) using the source. This was to get support for my hardware, but that was about a month ago. I do not see anything in /var/log (X, demesg etc).

Debian Configuration :: Proprietary Nvidia Drivers Stopped Working After Upgrade

Apr 5, 2011

My GNOME system stopped using the proprietary NVIDIA drivers after the recent dist-upgrade to v6.0.1. It was working perferctly before that.

My inxi output:

When I tried to configure the screen resolution using NVIDIA X server settings, I was told to run 'nvidia-xconfig'. I ran it, restarted X but my resolution is still stuck at the maximum of 1024x768. I've tried running the above many times with the same results. I even tried aptitude reinstalling but still the same.

Ubuntu Networking :: Wireless Internet All Of The Sudden Very Slow?

Jul 14, 2011

I installed 11.04 last week. Everything was working brilliantly until I turned on my laptop today. Now my wireless internet is running soooo slow. Requests take like 5 seconds, then it loads the page for about 10 seconds. Last night it was running fast.Chrome/Chromium/Firefox all run super slow. I tried turning off wireless-N and using G instead, but that didn't help. My windows 7 desktop is not experiencing the same problems in Chrome, or Firefox. I'm not sure if it's updates that I installed yesterday that didn't take until I restarted today

Debian Configuration :: Cannot Browse Internet While Torrenting

Jul 28, 2015

After doing updates to get current with Debian Jessie, I've noticed very annoying network problems going on.

This all happened while also setting up a media server box which led me to much confusion, much of what is described here [URL] ....

I've started this new thread to try to diagnose and properly take care of this specific problem alone:

Browsing the internet becomes very slow, unbearably to the point everything keeps loading up forever. This only happen while having a torrent application opened, the effects are almost immediate, closing the application and browsing resumes as normal.

How about throttling back torrent? This does not work, it even doesn't even need be at top speed. With bare minimum connections and speed will still lead browsing to a crawl.

Even so, every other device on the network is un-affected, router and other PCs continue to browse and respond very well, making it a specific on the computer in question (but also happens on my other debian jessie machine).

Can I even reach the internet? Yes I can, and this is the weird part... I can ping, solve DNS and almost everything else without issues, the only thing affected is actually browsing the internet.

I'd even setup DNS cache with dnsmasq to see if it could speed things up. Disabled ipv6, and trying pretty much every method I could find.

Having pretty much ruled out dns problems and internet connectivity, I'm at a loss for what to look for and try. Only symptom I can describe now is that the browser will start to load up webpage but never completes... but only while torrent is active.

My current setup:

I'm on Debian Jessie, a desktop with eth manually connected. Using dnsmasq for dns caching. Disable ipv6 on the network (by the way, it keeps disabling it self I dunno why).

Running KDE with ktorrent as the client. The same thing happens on my setup media box, also Debian but with deluged running instead.

Browser in question are Firefox and Chrome, both have issues with this.

Turns out it was just a setting in my own router, that apparently limits numbers of connections made, meaning while torrent is working other connections were sure dead.

But it also happens when lots of connections are being made in other ways too. The router in question is Humax HG100R-L2, provided by my ISP. The setting is in the firewall section called IP flood detection.

Debian Configuration :: No Internet Connection After Reboot

Feb 20, 2016

I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list

Code: Select allroot@i67svof:/var/www# ifconfig

          collisions:0 txqueuelen:0
          RX bytes:36463 (35.6 KiB)  TX bytes:0 (0.0 B)

My HWaddr doesn't look that well :) 'ip addr' prints this result:

Debian Configuration :: Eth0 Connects But Don't Have Internet

Dec 17, 2010

I installed Debian Squeeze on my system two days ago, using a wired connection to internet (which worked fine). After that, I had to install the non-free wireless package in order to scan wireless networks. It now works fine, and I can connect and get to internet. But with wired connection, i connect via eth0 and none of my applications work. And they're not in offline mode.Also, i already went here: URL,,, and I checked if that was my case. I tryed what they say several times in some different ways, but I still can't connect. Even more, if I change something like they say, I get "unmanaged device" and I can't even connect to the internet. And the wired connection works, I'm using it right now on my ubuntu 10.10.

If you want more information, I just tried to ping sites like google.com or ......com using network preferences and it does work, it gets 100% of the packages back around 50ms later, so the internet appears to work. Also, when I connect via wireless, everything works perfectly.

In one of my customers, the new internet connection have no public IPV4(using GCNAT), only public IPV6.

And there are various services that require external access, like, vpn (openvpn), a java/web system, ssh, rdp(windows).

fileServer(by vpn).

All is running ok in IPV4.Maybe, the solution is a NAT 6to4. We know this is the future, no more public IPV4.

Debian Configuration :: WiFi Connects But Can't Ping - No Internet

Aug 27, 2015

I've been using Debian for about 6-7 months now. I've had a bit of a major networking problem for the past 4 months or so that I've been trying to fix - specifically, it started when I upgraded to Jessie. I can connect to wifi just fine, and sometimes I can even use the internet for brief periods of time (exceedingly rarely). Then... nothing. No network access, period. I can't ping any outside servers, I can't ping other computers on my network, and I can't even ping my router. Pages I try to load just stay "connecting" for all eternity, network printing fails, and so on.

So after four months of searching online (I've read through way more wireless documentation than I care to say), I finally gave up and admitted that maybe I screwed something up during upgrade to Jessie (as a matter of fact, I did, I had to do the upgrade in two increments [somehow] because my root partition was too tiny by mistake) and I did a clean install. Since I had /home on a separate partition, I was able to keep all my user files, but all settings regarding networking were wiped. So after installing firmware-iwlwifi so I can use my wireless card, I tried connecting to wireless! Success! Then I tried connecting to the internet... success! Briefly. The next morning I tried using the internet again, and it failed in exactly the same pattern as before.

I don't know much about what's going on here, but here's what I do have available:

I do have to use firmware-iwlwifi, which I installed by doing apt-get install firmware-iwlwifi. I don't think it's an issue with the wireless card itself (hardware-wise), the laptop dual-boots Windows 7 (that I never use anymore), and Windows 7 is able to connect to the internet just fine. Connecting directly to my router by ethernet cable works fine, I have perfect internet/network access then.

I can confirm that my laptop is receiving an IP address and that it is using ARP correctly to get the MAC address of my router (I confirmed this by doing the arp command, it has the MAC address correct, I checked from another computer with my router's config page) All other computers on my network work perfectly with my router. To confirm the router/its configuration isn't at fault, I did a full factory reset of the router, but to no avail.

Out of curiosity I tried installing Wireshark (using an ethernet cable to download it) to monitor what happens when I try to access a webpage. I'm no expert on networking, but I noticed something out place when I compare a capture from the affected computer to a capture from one operating normally - there are a lot of STP packets showing up. I did some checking around, it looks like STP is involved in bridging and more complex networking setups (involving switches, for example)... but it shouldn't be found on a home network, especially where there's no bridging whatsoever. These STP packets don't show up on packet captures done from any other computer. I've attached a packet capture from the affected computer here, since the forums won't let me attach a .pcapng file.

Here's the output from a few commands I ran during past troubleshooting sessions:

Code: Select allsudo ifconfig
eth0      Link encap:Ethernet  HWaddr e0:db:55:b5:fe:06 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:12455 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7781 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000

Debian Configuration :: Connect To Internet Through Wireless Card?

Jun 9, 2010

I am currently trying to connect to internet through my wireless card, after half day's effort I reached to this point:

/******The following error appears in the dmesg kernel ring buffer output:
ipw2200: ipw2200-bss.fw load failed: Reason -2
ipw2200: Unable to load firmware: -2
ipw2200: failed to register network device
ipw2200: probe of 0000:02:03.0 failed with error -5*********/

I found a solution from Intel website saying that the problem might be: "firmware in wrong location or wrong firmware version". So I proceeded to download the firmware and placed it in /lib/firmware. Also I tried to use menuconfig to enable loading firmware via hot-plug, but I think I have done something wrong when I was configuring the hotplug and firmware.
