I have tried hostname and ping in a cluster machine, with different outputs. I am wondering what is the difference between the two? For example, on the same machine, hostname outputs node4.XXX and

ping -c 1 $(hostname)

outputs pc333.XXX.

Hi,

I am using FC9 and internet is working fine on it. Well, I ping to google, it is resolving but if I ping by hostname to other LAN computers. it gives error : unknown host. but if i ping with IP address it is pinging.

NOTE : 1) My firewall is acting as a dns server and other windows systems are resolving it.

My ISP (Insight if you know them) says I had open ports. OK I did! Shame on me! I'll blame my $15.00 router but I know it's my fault. OK took care of that.

I have a home network of a few computers, one of which is an iMac running Mac OS and another is a PC running Windows 7. The PC is able to ping the iMac both by IP and hostname, but the iMac can only ping the PC by IP. I'd like it to be able to ping the PC by hostname as well.

Find mobile device on network 17 weeks 5 days ago

I'm trying to write a small program that will poll the network for certian ip addresses or mac addresses (though mac doesnt seem to show up past my WAP)

My networking isn't very strong but many mobile devices don't support ping on the network (im looking at you iphone)

is there a fairly easily to poll all network addresses on the network regardless if they will reply to ping?

[ubuntu] DNS does not resolve 2 years 43 weeks ago

I've had this problem forever, but now it's become a work issue and not just personal.

I cannot ping any hostnames on our LAN

/etc/resolv.conf has both name servers configured correctly. I can ping the IP, but can't ping the hostname. I know it's something really simple, just can't put my finger on it.

Here's a rough scheme of my network: - http://i.stack.imgur.com/zrlJJ.png The network is divided into VLANs. The linksys device is connected to a VLAN20 access port.

I have found (and tried to solve for the past 6 hours) an intriguing situation.... I have a new install of ubuntu server 12.04 on fairly old hardware (core duo, two onboard network controllers). I have 2 networks that are connected but usually kept separate. one is 192.168.10.x and one is 192.168.5.x. If I set up both of them i can ping computers in the 10.x network, but not in the 5.x network.

Sorry to bother around here.
