Networking :: Mount -t Smbfs Error Can't Resolve Hostname
Sep 24, 2009
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.
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
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 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.
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 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.
Cannot connect to internet via Firefox or Midori on my Dell Inspiron 8200 laptop with a Netgear wireless card. However, I can update via yum, I can ping google from the CLI, I can ssh to my desktop, I can point a browser to find my router which /etc/resolv.conf points to, but can't get a browser to resolve hostname. I'm posting from a different machine (desktop), here is my /etc/resolv.conf:
Command used as root to mount a Windows 2003 server share to Linux Red Hat 4 x86-64 on Dell: mount -t smbfs -o username=user,workgroup=domain.edu,password=password //server.domain.edu/h$ /mnt/test The mount is successful, but only root can write to the mount. How do I set the permissions on the mount to allow certain users read/write access to the share? I am logged on the Linux server as the same user who authenticated the mount. The user can read write on the Windows server share, but not while loggged into the Linux server.
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 just built an AMD Phenom II Six Core with 4 Gigs Ram a 160Gib / and swap, and (2) Two Tb mirror for Raid (data storage) I had been using DMRAID in the deprecated box but this box has MDADM v3.1.4 - 31st August 2010 from source (on MDADM wikipedia).
I have no permission problems with using the raid and dmraid is un-installed. The raid is working perfectly and is mounted in my fstab with ext4 defaults 0 2 as my options.
I have two exports /media/raid/Test /test
Both show IP and subnet on the showmount -e for the server. I can mount the test just fine on the server. I cannot, however, mount the /media/raid/Test error: mount.nfs: access denied by server while mounting hostname:/media/raid/Test Using dmraid I am able to have the deprecated box export and mount nfs shares from the raid but using MDADM on the new computer, I cannot. I get similar results with pointing MYSQL's data folder to a location on the "/media/raid/Database" (even with apparmor entries).
Mount a Windows share where my user account has admin privileges. All permissions granted to the share on the windows pc side.Mount statement is as follows:sudo mount -t smbfs -o username=johndoe //winname/directoryname /mnt/tmp/Share mounts ok but does not let me create or write to an existing file. When I select Properties on the directory it says that permissions are unknown on the share looking at it from Ubuntu.
I have the following two lines at the bottom of my /etc/fstab
Quote: //172.16.6.15/e /tmp/e cifs _netdev,iocharset=utf8,credentials=/root/.smbcredentials,gid=0 0 0 //172.16.6.15/e/Public /var/www/index/pub cifs _netdev,iocharset=utf8,credentials=/root/.smbcredentials,gid=0 0 0 My server address is 172.16.6.1.
If the destination (which is my workstation desktop) 172.16.6.15 is offline when the server tries to boot, the entire boot procedure halts with the following message: Unable to find suitable address. mountall: mount <destination> terminated with status 2 The problem is that my server runs headlessly, and every time something silly like this happens where you'd normally expect the OS to continue regardless, I'm forced to plug a monitor in and diagnose on console
So my question: Is there any way to make it proceed with the boot normally despite the host being unreachable? I could probably chuck a mount command into crontab or /etc/rc.local or a /etc/network/if-up.d script, but isn't this the way it really should be done (/etc/fstab)? If so, then we shouldn't expect the entire boot to halt just because a network share can't be mounted, right? While on the topic of a headless ubuntu server 10.10 not booting without some kind of intervention, I have yet another issue: If the server goes down without proper shutdown (power failure, for example) the grub menu displays the kernel choices and there's no countdown timer. Instead, I have to manually press enter to continue the boot. Is there any way around this? Clearly this should not be the case for a server distribution
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.
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'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.
I have squid on my RHEL5 server and a no of windows clients ,on clients some sites opened without any error but some sites whilw opening says unable to resolve hostname ,why this kind of problem ?This may be DNS problem ,but it should happen for all address not some .
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).
I'm running Ubuntu 10.10 with all the updates. I'm in an NFS/NIS networked environment. My mounts eventually work, but mountall fails with this message in /var/log/boot.log: mount.nfs: Failed to resolve server myservername: Name or service not known
Here's the entry in /etc/fstab: myservername:/nfs/share/path /mount/path nfs rw,_netdev,bg,hard,intr,rsize=8192,wsize=8192 0 0
Here's the host entry in /etc/hosts: 123.45.678.901myservername
I've noticed that mountall seems to be trying to mount my share before it has network access.
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 # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface code....
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.
I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.
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'
I'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.
Here's the not-so-quick-and-dirty description of the situation:
I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.
I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).
The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.
Every machine has an equivalent resolv.conf:
As an example, I will show the output of a handful of my development machines:
I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:
columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200
Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL: - Ping by IP address - Ping by hostname - ssh, scp, vnc, etc by IP addess
Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.
Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.
Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.
Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.
I'm trying to ping another Ubuntu computer on my local network. If I try doing,ping <hostname>then I get the messageping: unknown host <hostname>however, if I doping <hostname>.localthen I get a response back. I was wondering how I can change it so that I can ping without having to append .localI've installed winbind and modified my /etc/nsswitch.conf file but this has made no difference.
I have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".
I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.
Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".
How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.
Evolution has balked at every webaddress I've thrown at it: Example: Code: Could not connect to imap.google.com (port imaps): Host lookup failed: imap.google.com: Name or service not known same thing happened for smtp as well as the canonical names provided by nslookup.
I was able to succeed in connecting my email finally by using the IP provided by nslookup, but still am unable to get my google Calendar to connect: Code: Cannot open calendar: Unexpected HTTP status code 2 returned (Cannot resolve hostname (www.google.com)) No proxy settings configured in Evolution or Fedora and none needed. Lemme know what else I can provide.
im trying to get a network setup i followed the instruction via gentoo wiki samba what i have done
[Code]...
then i did chmod 777 to the shared folders on both machines went into nautilus it sees the folder but it will not mount the folder showing the error msg:"unable to mount location failed to mount windows share" ive been searching unbuntu forums opensuseforums and google for an answer to this issue but as of right now anything that i have tried to do has failed and nothing seems to be working.
