Ubuntu Networking :: Can Download Packages (apt-get) - Ping If Disconnect WAN

Jun 7, 2010

I have 2 nic cards. One I use for my LAN and the other for my WAN (ftp, web). I am using a fresh install of Ubuntu 10.04 LTS. If I disconnect the WAN I can download packages (apt-get), ping etc. If both nic cards are active I cannot do either. This behavior is the same whether or not iptables is enabled. BTW I am using the server version. I was only able to find examples that used a GUI, nothing from the command line.

Ubuntu Networking :: Unable To Ping Over Wireless But Can Ping Over Wired?

Jul 24, 2010

I have two machines on this network, one running Ubuntu and the other running Fedora.

When I'm using the Wireless network on the Ubuntu machine, I cannot ping the Fedora machine. Everything else works. I can browse the net fine.

If I switch over to the Wired Network then I can ping the other machine.

I don't understand why ping doesn't work only over the Wireless. I can ping the router so I'm guessing it's getting blocked by the router but I didn't block ICMP traffic.

I tried asking on IRC and they ran out of ideas too to find out where the problem is.

Networking :: BIND9 SLOW Ping When Ping By Hostname

Feb 1, 2011

I just installed my first EVER bind DNS server. I am running bind9 on Ubuntu 10.04. Everything seems to be working great except one thing: If I ping a host that I have set up in bind by its HOSTNAME the pings take 5-6 seconds to reply/print to the screen between each echo response. If I ping by the host's IP address, they echo back very quickly.

I have read that IPv6 can cause this, but I have disabled it in /etc/sysctl.conf and the problem still exists.

I know everyone says this can't be a DNS issue, but this never was an issue with dnsmasq (which i was using prior), and it doesn't make sense that the ping are ONLY slow when pinging by hostname and not IP.

Configs below:

Ping by hostname - there is a 5-6 second delay between each one of the responses:

Code:

Ping by IP - the responses come VERY quickly one after the other:

Code:

/etc/resolv.conf:

Code:

Code:

rev.0.168.192.in-addr.arpa:

Networking :: Can't Ping Past Gateway / Can Ping Server From Outside

Apr 29, 2010

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

Networking :: Ping Connection To Router OK But No Ping Between Boxes In LAN

May 26, 2010

I have Mandriva One 2009.0 (192.168.1.100) on one box and Mandriva Free 2010.0 (192.168.1.118) on the other. I can ping router (192.168.1.1) from both of these boxes but I can't ping one box to the other and the other way around. What's going on?.

Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.

Ubuntu Networking :: Wi-fi Disconnect Every Few Hours?

Sep 25, 2010

Periodically, about 3 to 5 hours, Ubuntu disconnects from my wi-fi network and doesn't reconnect until I restart the router.This is an Ubuntu specific issue, since it doesn't happen when I boot into my Windows partition, and it doesn't happen to other computers on the network.

Ubuntu Networking :: Disconnect The Network On Shutdown?

A month ago I had (and still have) a weird problem were leaving my switched off computer plugged into the network killed the whole network.

well I have found a fix, if I disconnect my computer via software (Right click and disconnect "eth1" and shut down the network will remain up. I want to make a script that runs on shutdown that simply disconnects "eth1". Are there any pre-made shutdown scripts in ubuntu that I can simply add "eth1 enabled = 0" or something.

Ubuntu Networking :: Wireless Connection Not Working After Disconnect It

Jan 9, 2010

I have a cisco linksys wireless adapter (WUSB600n) which, most of the time, great when booting up. But mostly after some time (1min- 1hr.) it disconnects. When checking the status I can see some of the networks around me, including mine. But selecting it doesn't do anything. I searched the forums and tried:

sudo dhclient
and
sudo /etc/init.d/networking restart

But still no connection; the only thing that helps is rebooting.

Ubuntu Networking :: Disconnect Pc From Switch It Sometimes Connects Before It Times Out

May 19, 2010

I have my internet connection via a wireless USB adapter and that works fine. Recently I connected my pc (Ubuntu 9.10) through a wired switch to my modified xbox so I can watch my videos in my office. I can share my content with my xbox (except for the items on my external USB HD's - I am working on that and will post that question elsewhere) but when I have my PC's wired connection plugged into the switch I can not surf the web or check email. It gets stuck at resolving host and then times out. If I disconnect the pc from the switch it sometimes connects before it times out. Usually it is quicker if I reboot without the wired intranet connection.

Ubuntu Networking :: Wireless Network Connection Disconnect-reconnects Every 5 Min
