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.

OpenSUSE Network :: Nmblookup Resolves But Cannot Ping Netbios Names Or Ping FQDN

Feb 23, 2011

This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.

Ubuntu Networking :: Ping To Offline Host Returns Arbitrary Ip Address?

Mar 17, 2011

A brief description of my network:It is a small home network consisting of an Ubuntu 10.04LTS server edition, an Iomega ix2 NAS, a WinXP pro server and several family laptops.This is all routed through a Netgear WNDR3300 home router. All are assigned IP's via DHCP and all but the laptops are static (via DHCP though). The WAN address/DNS is assigned via DHCP from my ISP.The problem:When one of the machines is offline, Ubuntu does not resolve the netbios name correctly. No surprise here. But what is happening is that it is finding some arbitrary machine on another network. Below is what a ping to an offline host reveals:

Code:
ping -c3 hostname
PING hostname (204.232.162.92) 56(84) bytes of data.
