http://forums.fedoraforum.org – Hi Friends, I am using Fedora 16 32+ bit distro. How do I check if my dns service is working or not? I tried the following command based on my very little knowledge of network things. Below is the output to a few commands. Thanks. I use a router to connect my pc via LAN and a laptop via wireless. Code: [root@localhost john]# ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_req=1 ttl=64 time=0.606 ms 64 bytes from 192.168.1.1: icmp_req=2 ttl=64 time=0.579 ms 64 bytes from 192.168.1.1: icmp_req=3 ttl=64 time=0.568 ms 64 byte (HowTos)

I've got a bit of a basic networking question here regarding ping.

When pinging a particular host on a completely different subnet, I get a response like this:

PING myhost.example.com (1.2.3.4) 56(84) bytes of data. 64 bytes from 1.2.3.4: icmp_req=1 ttl=115 time=1.88 ms 64 bytes from 1.2.3.4: icmp_req=2 ttl=115 time=1.66 ms 64 bytes from 1.2.3.4: icmp_req=3 ttl=115 time=1.96 ms 64 bytes from 1.2

I can ping github.com but I can't ssh into it.

Why is the ping command outputing different results for these two instances?

$ ping -c 3 www.google.ca PING www-cctld.l.google.com (173.194.79.94) 56(84) bytes of data. 64 bytes from pb-in-f94.1e100.net (173.194.79.94): icmp_req=1 ttl=48 time=24.7 ms 64 bytes from pb-in-f94.1e100.net (173.194.79.94): icmp_req=2 ttl=48 time=24.5 ms 64 bytes from pb-in-f94.1e100.net (173.194.79.94): icmp_req=3 ttl=

I'm running fedora 17 now for a few days.

I'm a little new to all the intricacies of Linux workings, so please bear with me if this is a dumb question.

I'm using Linux Mint 12 and I have an Asus PCE-N15 wireless card, which is running the Windows driver. Anyway, periodically I completely lose my connection, though Network Manager and iwconfig still claim that it's fine.

I have a server which I've been using at home (with no problems) for about a year. I recently upgraded the memory from 2x2GB to 2x4GB and updated the operating system to ubuntu server 11.10. Following this I have network problems with the server after a few minutes.

Simple question: how to make ping on Linux to show line numbers in output?

I mean:

1 64 bytes from www.site.com (2.7.1.1): icmp_req=1 ttl=247 time=17.9 ms 2 64 bytes from www.site.com (2.7.1.1): icmp_req=2 ttl=247 time=16.1 ms 3 64 bytes from www.site.com (2.7.1.1): icmp_req=3 ttl=247 time=16.1 ms

OpenVPN struggling 18 weeks 5 days ago

I've got some problems with my OpenVPN setup.

The Setup: -> Ubuntu Server 12.04 -> Two active NIC's: eth0 (default): 192.168.1.0/24 eth1: x.x.x.x (external ip)

I've managed to get the routing to work so i can connect to the outside world with the eth1 NIC.

holmen@filserver:~$ ping -I eth1 -c 3 www.linuxquestions.org PING www.linuxquestions.org (75.126.162.205) from 192.168.1.2 eth1: 56(84) byte
