Any attempt to load a webpage gives a Cannot Resolve Hostname error. i can ping [URL], but cannot load the page. However, the page will load by typing its IP address [URL] I have been trying to figure this out for days. cat /etc/resolv.conf nameserver 192.168.1.254
View 9 RepliesSo 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 am trying to mount a NAS device using the hostname on my linux computer (running slax)
The command I am using is
mount //hostname/sharename /mnt/test -t smbfs -o username=***,password=***
i am getting back the error
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?
This morning it would not boot; when I tried to wake up the system, it gave me a bunch of errors, the last ones being as follows: "mount error: could not resolve address for servername: No address associated with hostname mountall: mount /media/shares [1402] terminated with status 1" I am writing this in Win 7 since I lost ubuntu. I am using ubuntu 11.04.
View 2 Replies View RelatedMy problem is that my debian in hard drive 1 wont load, gives me a fatal error.
This is my computer:
Hard drive 1 (1TB): broken debian 333gb, windows7 666GB (approximately)
Hard drive 2 (250GB): debian (working fine, im using it now).
Details: I tried to install some webcam software thing and I think somehow i deleted some system files... ...So now when I start my computer, grub loads and i choose Debian on hard drive 1,i click it but when it goes through the list of things, it says
FATAL ERROR /lib/modules/2.6.32-5-amd64/kernel/fs/fuse/fuse.ko: No such file or directory
And it just goes to a blank screen with a blinking cursor.
Now that's not all. I did something else wrong... I ran Gparted from a usb stick to create an extra partition on hard drive 1 because i was trying to install another linux on it or something so I can access my computer.
But, when I tried to shrink it and create an extra partition on the disk of about 150gb, it was taking so long and i read that it may take about 40 hours, so i turned it off after a few hours. So, I may have created more problems than my original problem.... I can still boot into Windows 7 though.
So now i have:
Hard drive 1 (1TB): broken debian about 120gb, windows7 666gb (approximately), free partition
Hard drive 2 (250GB): debian (working fine, im using it now).
Also, of interest: When I look at the folders of the messed up debian, there is nothing in the /lib/modules/2.6.32-5-amd64/kernel folder. Empty.
So basically. my problem is that I get the fatal error, and then maybe i create some extra problem by stopping the partitioning when it wasnt done. so please help me try to fix the fatal error first
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.

I've installed newest Debian (Squeeze) and then on fresh system made instalation of VirtualBox OSE as it is written on http://wiki.debian.org/VirtualBox.
I've also created virtual machine, however when I try to run it I got error message:

I 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've a fully working openvpn network but it works only using ip address.Clients should comunicate each other thought the server. To semplify the managment of clients I'd like to use their hostname instead their ip. there are a way to achieve it?Now openvpn assign ip address to the clients, but if is needed I can install other software on the server, it's a Debian machine.

View 2 Replies View RelatedI 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).
I have three Debian systems running, along with several XP laptops, PS3 and two DirecTV systems. I use two of the three Debian systems as media servers, and the third is an older system mostly for playing around with. My home network is running fine with the following nuisance. The two newer Debian (Lenny) systems are <barney> and <mitzi>, the older is named <oscar>, running Debian Sarge 3.1. From either locally or remote login to <barney> and <mitzi> I can ssh into either of the other two systems, however when logged into <oscar> I cannot ssh by name to either of the other systems. e.g. ssh: mitzi: Temporary failure in name resolution..However, from <oscar> I can ping outside my network (e.g. ping www.google.com) with no problems.I can also ssh to the other systems via IP address, just not by name.
I've compared the /etc/ssh/ssh_config, /etc/resolv.conf, /etc/ssh/sshd_config and other files between the two systems and not seeing anything peculiar. arp, route, etc., don't show different behavior between the systems either.
I have squeeze with gnome. Various apps let me log in as root when needed to but if I logout as a user and try to login as root it won't let me (won't authenticate password). I had this problem before and reinstalled Debian and definitely checked for it to allow me to do this and it worked for a while after new install. Apparently some update overrode my preferences. This is a major defect and may force me to abandon Debian. I don't use root often but I don't have any use for a operating system that won't let me use it. Anyone know how to correct this. I am not interested in using a terminal on a regular basis or ever for that matter.
View 14 Replies View RelatedI've just installed Debian Squeeze from a live CD. When I open a web browser (be it iceweasel or epiphany) and try to go to google.com, it tells me it can't resolve the host name. [Edit: They do, however, allow me to go anywhere on debian.org, minus the search feature] I also get the same error when I try to go to my website running on a local server. However, when I type the server's IP address (192.168.0.10), it goes to the website fine. Basically, any program I run that needs to resolve a host name returns an error, with the exception of the host command:
I've tried changing my DNS server IP from 192.168.0.1 (my router, configured to provide DNS) to 192.168.1.254 (my internet modem, also configured to provide DNS). That didn't help any. Then I changed my DNS server IP to the same one used by the modem, and now everything works.
I've tried googling my way out of the issue, and I've found where someone had the same issue as I've got and fixed it by adding "blacklist ipv6" to their /etc/modprobe.d/blacklist.conf file, but that didn't work for me.
So, recap: Why does resolving domain names fail for certain applications (except the "host" program) when the DNS server IP is that of my router or modem (which works fine for all of my other computers), but suddenly works when I point the computer straight to my ISP's DNS servers, and how can I permanently fix the problem?
I 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.

I 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.
Is there away to resolve the hostname after creating a new subdomain. So we don't need to wait internet need some times to able to resolve the hostname. For example, if I add new subdomain to "test.example.com", I can directly ping to this hostname from internet.
View 3 Replies View RelatedI just installed Debian with the latest testing iso, and I'm having problems connecting to the web via browser. I can ping hostnames (i.e. google.com, debian.org, etc.) from the terminal and it resolves just fine, but if I try to load a page from Iceweasel or Epiphany it says the page won't load because it can't resolve the hostname. Can someone tell me what I'm missing?the detail that I'm running amd64. I've checked iptables and found no entries, and for good measure I flushed it to be certain. I also checked resolv.conf but that looked normal, just a nameserver entry pointing to my home router. I'm new to Debian, but have used Linux for years, and I'm genuinely stumped. I'm sure the solution will smack me in the head for its simplicity, but nonetheless I need at least a shove in the right direction.

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'

As 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.
I'm trying to set load balancing over 2 ISP link on a router / firewall running Debian Jessie.
There are iptables rules for balancing and forwarding:
Code: Select alliptables -t mangle -A PREROUTING -j CONNMARK --restore-mark
iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j ACCEPT
iptables -t mangle -A PREROUTING -j MARK --set-mark 10
iptables -t mangle -A PREROUTING -m statistic --mode random --probability 0.5 -j MARK --set-mark 20
iptables -t mangle -A PREROUTING -i $wan1 -j MARK --set-mark 10
[Code] .....
There are iproute2 rules:
Code: Select allip route add 172.20.0.0/24 dev eth0 src 172.20.0.150 table WAN1
ip route add default via 172.20.0.254 table WAN1
ip route add 192.168.0.0/24 dev eth1 src 192.168.0.150 table WAN2
ip route add default via 192.168.0.254 table WAN2
[Code] ....
The packets marked as 20, theoretically routed via table WAN2 via 192.168.0.254, are lost.
The WAN2 gateway is working if I set as default without balancing.
I disabled the rp_filter module on all interfaces and I installed xtables-addons-dkms.
I also try this but I had trouble with forwarded connexions.
I would like my CPU to be overclocked, while retaining frequency scaling capabilities. The CPU is a Core2 Quad Q6700, with a stock speed of 2.67 GHz. In my BIOS, I can manually increase the FSB, but if SpeedStep (EIST) is enabled, the increased FSB is ignored by Linux, and the max speed remains 2.67 GHz. If I disable SpeedStep, then the CPU successfully runs at the higher speed I would expect, but does not scale down when under low load. As it is now, I am only running it at 2.8 GHz.Does CPUFreq *require* SpeedStep to be enabled in the BIOS?
