View 2 Repliesi searched the internet on how to resolve IP to hostname in my internal network. However, i could not find any solution to it. Any gurus around have any knowledge on this? i have tried whois, dig and nslookup however it doesnt give me anything.
View 1 Replies View RelatedI just built out an Ubuntu Server 10.04.
My problem is setting the hostname. I cloned the machine, then normally on the clone, I would change the /etc/hostname and /etc/hosts file.
However, when I do this, upon restart, I get the message, "init hostname main process (some process number) terminated with status 1"Then, when the machine finally boots, the hostname is set to (none). Literally has braces like: user@(none):
I've tried: sudo hostname machine_name but it says can't resolve hostname (none).
I've Google'd around a lot but can't get it. It may have something to do with 10.04? I have been using 9.04, 9.10 with no problems.
eric@(none):~$ cat /etc/network/interfaces

I got my server set up with 10.04, and with everything installed: DHCP, SSH, Samba, VBox, etc.
DHCP, SSH work fine, but I am having problems where I cannot ping the hostname of the machine.
It worked for a few minutes after I got everything installed and now it's not letting me connect via hostname. I can connect fine if I use the IP address. I cannot ping the machine by hostname unless I add it's IP address to the hosts file.
I am updating all of the company systems from Novell SuSE Desktop 10 SP2 to 11. We have several links on the desktops of users that are URL's. In version 10, I just did a Create Launcher, Type was Link and I could type in a URL. The LINK type no longer exist. I checked on my system at my desk which is OpenSuSE 11 and it also does not have the link type. I have been searching on the Internet for creating Launchers and then looking for information on creating links and have not been able to find anything. Can anyone point me to a good howto or document on creating URL link launchers (we have a system that runs Apache and from the users PC they click the link to connect to the server). I tried just creating a bookmark in Firefox and then dragging the bookmark to desktop and customizing icon. But, I build the systems at our corporate offices, and when I build, the IP address on the system is the actual IP and since it is not at the final location it can not connect, and the bookmark creation on desktop fails with error 'Unable to resolve hostname'

View 3 Replies View RelatedAs the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.
Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or anything.
So I recently upgraded from Debian 5 to Debian 6 and now for some reason I cant SSH into my server FROM my server. All of the following fail with the same error:
[URL]
They all come back with: ssh: Could not resolve hostname 127.0.0.1: Name or service not known. I never actually tried this before upgrading so I'm not sure if its caused by the upgrade, but I would like to get this fixed. Also, ping with all of the above hostnames fails as well. I can SSH in from other computers and I can SSH out from the server. For whatever reason, I cant SSH from the server to the server though.
I got an application deployed on Websphere Application Server on SUSE Linux V 10. We are accessing the application using the IP address in the URL. Please let me know how to configure the DNS, so that we can use the Host name in the URL and the Host name is automatically mapped to the IP address.
View 1 Replies View RelatedI have two computers.
Computer A = windows 7.
Computer B = Ubuntu Server 9.10
Computer B automatically receives an IP address from my router.
I can ping computer B from computer A using the IP address. I cannot ping computer B from computer A using its hostname.
My router did not show a hostname under it's active clients table. After some searching I found a threat where somebody suggested modifying /etc/dhcp3/dhclient.conf and adding 'send hostname "blahblah"' This allowed me to see the hostname in my router but I still cannot resolve it from my windows box.
I have a weird problem since yesterday that I can't solve. I can't ping / ssh my machine anymore using its hostname... says "unknown host", "network unreachable". I have no idea why - it used to work perfectly. I can still ping / ssh using the IP so it must be a problem of hostname not being resolved.
I have a dynamic IP (I'm at work...) but that doesn't seem to be the problem - network manager automatically adds a line in /etc/hosts with <mycurrentip> <hostname> (I checked, it's indeed the IP given by ifconfig and that I can use to ping/ssh).
2nd question: Another computer has a similar problem but slightly different: the hostname is resolved but points to a wrong IP (seen in ping or nslookup), different from what ifconfig returns. As a result, ping times out and ssh says "no route to host".
I am using a Dell Latitude D610 that is a few years old, and running Fedora 13. I do not think hardware is too relevant to my problem, nor is it an issue with my OS itself. I do not dare perform an upgrade to Fedora 14 at this point because this is an active work machine, for school use. To the heart of the problem, I am extremely irritated by the erratic behavior of Epiphany Browser (and just an hour ago, Midori). If I open more than a few pages at once (e.g. ctrl-clicking a bunch of Google search results) more often than not I get a chain of "cannot resolve hostname" blank tabs.
Oddly enough, I refresh the pages (one by one, of course - I don't know how to mass refresh) and they load properly! The problem is more prominent on Wikipedia - most articles have images embedded here and there amongst the text. When I visit the page, none of these show up - the page loads, and after I see the blue mercury-looking progress indicator shoot to the end, the spaces where the images should be are blanked and in the centers lie a little thumbnail of a grey photo with the corner turned up - e.g. generic-can't-show-the-image.
This is remediated by visiting wikimedia.org or refreshing the article itself, whereupon the images fall into place. The problem seems to carry over into Midori browser, which I installed a few hours ago just to use as an alternative - I say "had" because just now, the problem resolved itself. I strongly suspect that it has to do with my changing my cache size from 169 MB to 13 MB, which I did just now. That issue is now trivial; next question: Google Docs behaves very strangely in my browser. Whenever I make a normal alphanumeric keystroke, it shows up fine; but "backspace" and "delete" and "enter" are both doubled.
I double-space between my paragraphs by accident and when I make a mistake in my typing I often suck myself into a cycle of mistakes. E.g. "Polanrd" --> "Polan" --> "Pol" --> "Pold" (hitting backspace twice to trim off "rd", but Google Docs redoubles the keystrokes into four backspaces and I end up taking off too much and adding the lone "d" in the wrong place). The problem shows up to a lesser extent in the built-in chat, wherein backspace is not affected, but every time I hit "enter" my chat appears twice (as though I had hit enter twice).
Seismicmike here. My first post. I'll try to be as clear and concise as possible. For the sake of this post, I'm going to use 1.2.3.4 as a place holder for my public IP. On my web server, I would like to be able to access the /var/ftp directory through a web browser. I have successfully done so with Google Chrome, but I cannot access the directory in Firefox or IE. Both FF and IE ask me for authentication but then time out attempting to load the directory.
I suspect that there may be something up with switching to passive mode and/or that this issue may be more with my configuration of Firefox and not with the server (seeing as how Chrome works). Another possibility may be related to SSL. When I connect with FileZilla, I have to use the FTP over Explicit SSL/TLS option in order to connect. In any case I still would like to fix it. I would also like to avoid having to install FireFTP if at all possible.
Steps to reproduce (not that you can without my actual IP =J):
* Open Chrome
* Go to ftp://1.2.3.4
* Enter username
* Enter password

View 10 Replies View RelatedI am currently facing one issue with my network. I have several computers and this is what happens, everything works fine when I use the ip address, but when it comes to hostname.
-Windows computers can't ping/see the computer 5 (while it is running linux), but they can see computer 3 while running ubuntu 8.10 and computer 2 while on Mac OS X.
-computers 2 and 3 can see/ping everybody while on Mac/Linux.
-computer 5 can ping everybody.
-computers 1, 2, 3 and 4 (on every OS) can see/ping computer 5 while on windows xp.
Basically, the problem is with computer 5, it can see, but it is not seen by other computers (just when running ubuntu lucid)Computer 5 is supposed to be a printer server, so it must be seen by the others regardless of OS.When I ping computers 5 the TTL is 64, when I ping other computers, TTL is 128. I don't think this means anything, but I am not sure.Initially I thought this was a printer issue, but then I realized is something related to network when I tried to use ping/explore the computer 5 by ip/hostname (it works by ip, but not by hostname).Computer 5 is sending the hostname to the router properly, it appears in the dhcp client list.
I am trying to mount a NAS device using the hostname on my linux computer (running slax)
The command I am using is

mount error: could not find target server. TCP name hostname/sharename not found
No ip address specificed and hostname not found
I can do this mount from an older version of SLAX but i can't from this new version. smb:/ can find then through the file explorer window but I can't mount them from the command line.Is there something i am doing wrong?

I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
I have setup a home based web server to host a photo blog for myself and my friends. I will be running wordpress and possibly a phpbb3 forum. I'd like to open this to discuss server administration, server setup, and server maintenance. However, I have a pretty good start on all of those but serving a domain name to my static ip. Here my static ip is 24.10.202.144. I registered a domain through [URL]... It appears that I have the domain working to forward to my ip. However, I am still getting this output file from apache.
[code]...
I have tested the domain name across a few different computers on different ips. It works appropriately. I just want to make sure I have it set correctly on the (apache) server side of things. Then I can get more into Zone Editing etc.
