I understand that it has three elements, separated by periods, as in "a.b.c". Um, not necessarily. Your hostname is your computer's name to the internet. The one I'm typing on now is pollux.cis.ksu.edu. There's really only two components: pollux and cis.ksu.edu. The first is the hostname, the second is the domain name. If your field is asking for a fully qualified domain name, you'll use both: pollux.cis.ksu.edu. But how do you find out what your hostname is? Use nslookup on your IP address. acrux ~% nslookup 129.130.10.33 Server: zaurak.cis.ksu.edu Address: 129.130.10.3 Name:pollux.cis.ksu.edu Address: 129.130.10.33 The first two lines list the DNS server that's being contacted, the second two are the information you requested. Thus, this computer's IP address is 129.130.10.33, and it's hostname is pollux.cis.ksu.edu. Oh, yes, even Windows NT has nslookup (surprise!). Don't try it on DOS (a.k.a.

However, in this case, it's asking for the gateway DEVICE, which will be your ethernet card that goes out to the rest of the network, most likely eth0. John

RE: [expert] Network Questions to Ask?
Lester, Thats the ticket the gateway is your problem. A gateway is a network point that acts as an entrance to another network. On the Internet, in terms of routing, the network consists of gateway nodes and host nodes. The computers of network users and the computers that serve content (such as Web pages) are host nodes. The computers that control traffic within your company's network or at your local Internet service provider (ISP) are gateway nodes. Now note most addressing is done out of tradition but it might not be so were you are at also assuming you are on a class c network. So lets say that your ip address is 192.168.0.123 and your DNS servers might be located 192.168.0.1. so usually in this case the gateway is located at 192.168.0.254. But again this is left up to the admin who assigned the ip address. Your best bet is to ask the Windoze and NETWET guy :) what the gateway is. As soon as you get that you should be in like Flynn. You can also check your network settings by typing ifconfig at the console. and if everything looks good try to ping a site and if you get a reply your up.

Now, can you ping your NIC by IP address? For example, my computer is at 192.168.1.3, so I verify the operation of the network on my computer with: ccurley@charlesc $ ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3): 56 data bytes 64 bytes from 192.168.1.3: icmp_seq=0 ttl=255 time=0.1 ms 64 bytes from 192.168.1.3: icmp_seq=1 ttl=255 time=0.1 ms 64 bytes from 192.168.1.3: icmp_seq=2 ttl=255 time=0.1 ms --- 192.168.1.3 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 0.1/0.1/0.1 ms - - Part of my problem is that I am the only Linux user on campus.

It comes into play when you have a multi-homed computer (it is on multiple networks). I've also set it up as the default gateway, and had that work. - - We have to DNS numbers, and I put the first one in the spot where it - was called for. I think that's OK. Cool. Put them both in. Ping a well known domain name to be sure that it is working, netscape.com, or halcyon.com. There was a bug in NT's ICMP handlers that lead a great many NT admins to turn off ICMP (the protocol that ping uses). So check to see if the name is resolved, not necessarily to see if you get return packets. For example, ccurley@charlesc $ ping www.microsoft.com PING microsoft.com (207.46.131.30): 56 data bytes --- microsoft.com ping statistics --- 5 packets transmitted, 0 packets received, 100% packet loss I got an IP address, so my DNS is working. But they have ICMP turned off, so I never got a response. No problem. Halcyon.com runs Linux, and appears to have ICMP on, so: ccurley@charlesc $ ping www.halcyon.com PING www1.halcyon.com (206.63.63.35): 56 data bytes 64 bytes from 206.63.63.35: icmp_seq=0 ttl=45 time=254.8 ms 64 bytes from 206.63.63.35: icmp_seq=1 ttl=45 time=251.9 ms 64 bytes from 206.63.63.35: icmp_seq=2 ttl=45 time=261.8 ms --- www1.halcyon.com ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 251.9/256.1/261.8 ms is cool. - - But I'm not sure about my host name.

In my case, it is "charlesc". On my private intranet, I have a bogus top level domain, "localdomain". So my "fully qualified domain name" (FQDN) is "charlesc.localdomain". Now, I have a simple network here. HP, for example, has a much more complicated network (a Class A network). They have geographic subdomains. The Fort Collins facility is at "fc.hp.com". HP Palo Alto is at, I believe, "pa.hp.com". When I worked at HP in Fort Collins, my computer's host name was dwarf, so I was at "dwarf.fc.hp.com." So check with your network admin. If you have a flat network, it may well be your FQDN is, say, "lester.emmanuel-college.edu". If they have subdomains, it may be "lester.subdomain.emmanuel-college.edu". Your email address does not necessarily tell you your FQDN, because competent Unix admins can play games with sendmail to disguise your FQDN from the outside world, and a good thing, too, for your privacy. Also, in any subdomain, all host names on the same level must be unique. So check with your admin. Have the admin either approve your proposed host name, or assign you one. Whatever you do, make sure your DNS administrator is told, and adds you to the DNS database. Otherwise no-one will be able to find your computer by domain name.
