Ubuntu Networking :: Nfs Lockd Not Responding
Sep 29, 2010
I have been using 10.4 as a Linux NFS server to share it's storage with a number of Mac computers we use in the office. All the Macs are configured to connect to the Linux server using the mount_nfs command in terminal.I have been using this method to transfer files to and from the Linux server for a while. Today, I installed a number of standard Ubuntu updates / security patches per the standard GUI update tool.
Now, I'm getting "nfs server 192.x.x.x:/media/video: lockd not responding" error messages. I have not seen this error before, and I haven't changed anything else about the configuration of the Linux server or the Macs with the exception of the installation of the security patches.

i am using nfs on my network with server ip 192.168.1.10 (the exporting server)
and i am mount nfs partition in /etc/fstab and when i login into console using the
alt ctrl FX
i continously get the following error
lockd: cannot monitor 192.168.1.10
moreover the mount is somewhat irregular on host systems as i am mounting home directories on all the systems on network and authentication using NIS, when i try to open firefox in console it continusly gives this error and firefox doesn't open and then after a reboot again of the client workstation firefox opens

I boot some Slackware with PXE. All work fine except i can't fix the client lockd ports.NFS is compiled inside the kernel, so all modprobe.d options are useless.But rpcinfo -p on the client side shows me totally different ports.On the NFS server, the ports are ok, as i appended lines in /etc/lilo.conf Server and client kernels/modules are identical.

I'm have some desktop computers sharing my Centos 5 server diskpace through NFS. From time to time, without any warning, lockd bugs and all the users that are using GTK applications like Firefox,Gnome.get stuck.
My first atempt is to restart the NFS, but locked files persist because I can kill the lockd pid process, even using root account , I suppose this is because it's a kernel process. Here is the message error I get when restarting NFS matrix kernel: lockd_down: lockd failed to exit, clearing pid

I am running ubuntu 10.04 on a VMWare Server virtual machine. I have assigned the ubuntu machine an ip address of 192.168.17.101. The ip address of my Windows machine hosting the Ubuntu VM is 192.168.17.100.
From the Ubuntu machine, I can ping all other machines on the local subnet. But when I try to ping the ubuntu machine, it does not get a reply.
I have a clean, plain install and the only software I have installed is Nagios.

when I do snmpget -v 1 -c public localhost system.sysObjectID.0on the same machine the snmpd is running on- I get a respond SNMPv2-MIB::sysObjectID.0 = OID: ccitt.1when I send same request from another machine (using SNMPc program) - I see no reaction.I used "wireshark" to monitor packets, and I see the requests sent from the other machine. I also see them get to the first machine.

My current situation is that the command "sudo modprobe ndiswrapper" is not responding, nothing happens. I am using [URL] as my guide and the "sudo modprobe ndiswrapper" is my next step. Here is some general information that you might ask for:
I received ndiswrapper utilities from "Synaptic Package Manager"
I was using jaunty jackelop before hand and the instructions worked perfectly but I decided to update to Karmic Koala 9.10 (I first installed the cloud enterprise version and realized that was way over my head).

The server is a Dell 1650 1U server, which a fresh install of CentOS 5.3, formatting the drive in the process. It has two e1000 NIC's and based on the wiring eth0 is the public segment and eth1 is the private segment.Both nic's make a solid 100mb connection to the cisco switch, and I can ping both interfaces "just fine".
If I run nmap on a remote PC that is also dual-homed in this fashion, I get the same response as to which ports are open (essentially everything since I disabled iptables temporarily to troubleshoot this issue) on both interfaces, which would be the expected result.But... and here is the source of my confusion... I can see the server by pinging it, I can use SSH to make such a connection and log in, but I cannot get apache to "answer the phone" so to speak.Runing "tcpdump -i eth0" shows me that my browser on a remote PC is attempting to connect, but without reply.If I send my browser to the ip address of eth1, I get the default CentOS new web server page as is the norm.Nothing shows in my /var/log/httpd/access_log or error_log at all... apache simply isn't answering.The httpd.conf is the original, and the one line I attempted to 'adjust' was the "listen 80" line, which I added the ip addresses specifically, but that didn't change anything.I am unsure how nmap can indicate the port is open and there is a service behind it, when on the same PC that ran nmap, I cannot connect at all.Might anyone have a clue to toss me so I can work to figure this out?

My network manager application went missing a few days ago. I enabled it by right clicking on the taskbar above and opting for "show". It reappeared and worked fine. After I rebooted, however, it was there ok, but it doesn't respond to clicking at all. It has stopped working.

Currently have a problem with my LTSP server when using a gigabit switch with a megabit thin client.I am using K12LTSP with Fedora 9.The thin clients get most of the way through booting up then I get error messages saying:nfs: server 172.31.6.1 not responding, still trying.I don't get this problem if I use a 100 meg switch though.I have found several forum posts on the internet which all seem to point to the following webpage with a solution:However, when I make the recommended changes It doesnt make a difference.Below is an example of the default file located at /var/lib/tftpboot/ltsp/i386/pxelinux.cfg with its default settings:

I am running a 2 NIC system with the routing table for eth0 allows user access to the internet,etc. and eth1 routes to another private network (192.168.x.x). eth1 is configured to handle DHCP requests.When a device connected via eth1 boots, it requests an IP from the DHCP server. Using tcpdump, eth1 is receiving the request but is not offering a lease.dhcp.conf seems to be configuring the DHCP service correctly. and dhcpd is running.The host is running Red Hat Enterprise Linux (Server Edition) 5.1. Perhaps I need to modify fire-wall rules (or disable them on eth1 altogether)?

System: hp pavilion dv7 running ubuntu 10.04
Today my laptop battery died and after i plugged it in and restarted it said that networking was not enabled. hitting the networking key didn't re-enable it. i right clicked the wireless icon in the tray and clicked "enable networking" and it enabled it but no networks showed up as available and the networking status light on my keyboard stayed red. I've restarted the computer several times to no avail. anyone know what i need to do?

As i've installed the new fedora update packets ,i've seemed to develope a strange networking problem .. Network description Fedora 15 with 3 LAN adaptors eth0 > LAN (IP address 192.168.0.254)eth1 > network connected to a pppoe conection eth2 > WAN to another provider. Ok so let's ignore eth2 because i've disable mangle(i was using trafic shifting on some ports). So now i'm using it as a simple NAT server .. so the problem is : >>my server is not responding to the traceroute command is it should .. the network works thou but this is what i get.

I'm attempting to set up a server for performing diskless boots here. I'm using Gentoo 2008, and have followed the instructions here:
[URL]
I've gotten to the end of the basic DHCP setup, and I can not get the server to issue addresses. I've confirmed dhcpd loads up OK, and is running in top.
Here's the contents of /etc/dhcp/dhcpd:
Code:
# Disable dynamic DNS
ddns-update-style none;
# Assume one default gateway for IP traffic will do

My config works fine when enabled but after an hour the site stops responding at all. When I restart, flush or disable iptables it works fine again. Wondered if anyone could see any glaring errors I've made

I am an 'experienced perpetual newbie' using Ubuntu 9.04. I know a little about quite a few things but nothing past intermediate knowledge so:I am trying to set up a simple LAN between 'rhino' (192.168.1.102) and 'polly-laptop' (192.168.1.101). My router address is 192.168.1.1
From polly-laptop:
sudo mount rhino:/home /media/rhinohome
polly-laptop can access rhino:/home fine.

I have a strange problem where my machine will suddenly stop responding to connections while still remaining partially connectible. Here's an example sequence of events I have taken (numerous times). If anyone can spot something else I should check or has seen these symptoms before please let me know.1) System is using an Edimax 7318-usg, Ubuntu 10.042) Wifi connection is working, with power management turned off (iwconfig)3) Signal strength does not cause the connection to drop (confirmed with router logs)4) When in a ssh session on the problem machine suddenly the ssh session is dropped "host is down"5) When I attempt to re-initiate ssh it fails, no route to host...6) Pinging it fails, accessing a webpage hosted on it fails, all access fails7) The machine I'm pinging/sshing from still has a good network connection8 ) I check my routers DHCP leases, problem machine still has a valid lease.
9) Router still shows problem machine in routing & arp table & shows active traffic going to and from (I checked the routers states and bandwidth monitor for this)10) I try sshing and pinging the problem machine from the laptop on the local network, it still fails, no route to host, wtf?11) I go to the problem machine physically, wifi connection is up with decent signal12) ifconfig indicates it still holds an IP address13) I open a browser on the problem machine, any webpage loads fine14) I ping the laptop from the problem machine, ok15) I ssh from the problem machine to my laptop, it works16) At this point I ssh from the laptop to the problem machine, sometimes it works sometimes it fails(it seems that pinging/sshing the laptop FROM the problem machine sometimes makes it connectable again).
17) Usually if I wait a while the problem machine will randomly become connectable again at random intervals18 ) The only reliable way to make the problem machine connectable again is manually reconnecting it to the wireless network19) I tailed auth.log ufw.log, etc. nothing suspicious disallowing my ssh connection20) dmesg shows nothing unusual, as far as I can tell, just some activity negotiating WPA keys and suchBy looking at the timestamp for the WPA negotiation and cross referencing the router bandwidth monitor I can tell the WPAnegotiation doesn't make it drop the conectionSo that's it, lol.

I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Currently running Ubuntu 10.04. Recently had problems with panels not appearing but desktop responded as normal. NOW, it would appear my icons formerly occupying my desktop are gone, and i can no longer left or right click on the desktop or group select anything. All the panels function as they should, but now the desktop itself is not responding and as stated my desktop icons disappeared.

I bought a Philips CDRW/DVD CDD5263 from Amazon for my Acer Aspire One netbook. After plugging in both USB cords to the system, the drive is powered, will respond to the eject button on the drive itself, but I cannot do anything with it from the computer, namely watching DVDs. I have been using Ubuntu for about a year now, but I still don't know much about the inner workings. I would assume this is a driver or compatibility issue, but I thought I'd double check before returning it.

I'm trying to run xmonad, but the hot key alt+****+enter is not giving me the terminal.Is it because I haven't installed xterm?Right now I can't do anything on my machine because I cannot access terminal.I always boot to SLiM, and from there enter xmonad.By the way I'm running arch, I would post on the arch forums but I can't sign up since I need the terminal to run a verification code type thing

I have been looking at Ubuntu for a couple years and finally decided to give it a try on an old Dell laptop 1150.Managed to get it loaded on and it all came up, did the updates.But the desktop will not respond. When the mouse arrow passes over on the left side icons it will sometimes change the color of them but still won't do anything.I did a quick search but did not see anything relatedam an absolute rookie with this Linux thing. Did I make the right choice with Ubuntu?

I am having a strange problem with nautilus when I try to go up on level using either the up arrow or the breadcrumbs the button depresses when I click it but nothing happens. If I sit there and click click click about 2 dozen times it will finally respond. I just noticed this today. The machine in question is running 9.10. Maybe this computer is just junk, I mean it only has a 2.8 Ghz Pentium
