Ubuntu Networking :: NFS Server Is So Hard To Get Running
Mar 26, 2011
I cannot understand why a NFS server is so hard to get running..i tried everything.. googled and searched the forums to find guides and HowTo's but none of the works all i want is the server sharing /media (and all subfolders)everyone with access to the server from my should be able to mount the shares and use have all permissions on the shares..Now when i try the above guide, i can mount the share on the client but the subfolders are empty.
I currently have a centos 4.4 I believe running with a 250GB hard drive. I want to make an image of that hard drive. I have tried removing the drive and connecting it to my windows pc using an adapter that would allow my windows machine run the hard drive as it was a regular external hard drive. Of course windows doesn't reconize that drive since it is linux partitioned. I am thinking that I need to have the hard drive inthe box I am wanting to copy and put in a blank drive in the box that I want to copy to. And boot from a live CD and use cat or dd to copy it. I have seen the commands before bust I am thinking this is the only way. Basically I am wanting to have a duplicate of the drive and build a whole new server that is already all setup.I will just change the host name and assign it another Public facing UP. Is this correct? Oh, and the new server will have different hardware. Might even be AMD or intel different from source or destination.
I have an old unuseable computer at home that became useless after a hard disk failure. I don't want to spend money on buying a new PATA IDE HDD for it, so I was wondering if I can use a PXE boot server on my notebook (using a virtual machine with Linux) and boot a Linux on the old machine with PXE without using Hard Disk. It is possible? Do I will need to make some extra configuration or use some specific enviroment do do this?
I'm running Ubuntu 9.04 on an Asus EEE 901. I am going to be running this as a mail server and web server (light usage!). As I will only be connecting in by SSH I want to be able to manage the network connections via the terminal/command line. I am using primarily the wired interface but want to have the wireless connected as well incase (WPA encryption). Am I missing something when I can not find config files for nm-applet? What's my best way of doing this?
I'm trying to get a dhcp server running on my laptop. I want devices to be able to connect to a wireless AP I've set up (using hostapd) to then connect to the rest of the internet via my ethernet connection from the laptop.
However, I can't get dhcp to work properly. It always fails, leaving this message in the syslog
Code: Jan 19 15:49:15 lucid-laptop dhcpd: WARNING: Host declarations are global. They are not limited to the scope you declared them in. Jan 19 15:49:15 lucid-laptop dhcpd: WARNING: Host declarations are global. They are not limited to the scope you declared them in.
I've been the las 4 days setting up my first VPN (OpenVPN bridged). The server is up and running OK but when I try to connect I've got this message in the client log.
Quote:
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) TLS Error: TLS handshake failed
I have a private server which I stream media from, but since I've installed VMware running Windows 7 and set up Windows to used a bridged connection, so I can access the network drives in Windows. Now that I have done that, I cannot connect to my home server unless I have VMware running.
I only want windows running when I need it, but I need access to my server at all times.
I have a remote machine on which my server application runs. The remote server is linux based. What and all steps I would required do to IDENTIFY and SOLVE for following two problems
I have a single CentOS server with two separate NIC's. I was asked to install an internal Wiki on Apache but have that dedicated to one NIC so it's internal only. Then have just a site running on Apache on the 2nd NIC which is externally accessible. I have never done anything like this and would like tonow how difficult this would be on a single stand alone server that I have above?
To use squid i want to install linux in my 200 GB hard disk. I need guidance regarding to installation phase.A server which will be dedicated for squid proxy what things should I keep while installing my red hat linux operating system.I mean the partition sizes for swap ,root ,boot and any partion for squid cache should I need during making partitions ?
Am attempting to set a static IP address on a server (to be used with Mythtv) and is running mythbuntu 10.04 (apologies if this is the wrong place to post this). I can set a static IP address that is in the range of 192.168.1.x on other machines on the network but when I try with the server it is not able to connect to the network. When using the DHCP rather than manually assigning the address it is assigned an address with the 10.0.0.x range. Why is it doing this I have never have this problem on other ubuntu boxes (and this one prior to a format of the OS).
The router/gateway is 192.168.1.1 I did have a DHCP server on the mythbox before formatting it and I was able to assign a static 192.168 address and retain internet connectivity. But I have re-enabled the DHCP server on my router since formatting the box.
Removed hard drive from our office server to check model number (windows pc). reinstalled same hardrive and now i can't connect to server from the network (MAC). it gives me error code -43.
*Solved* I have been reading the following guide on how to use the VNC programs and a GUI to connect to my main machine from my laptop via my LAN and router:
[URL]
This allows me to control the server remotely, and run applications on the server remotely, with the GUI output being shown on my laptop, which is really neat I had Eclipse + PDT running on my server and had to stop it and start a new instance remotely from the laptop via VNC viewer, as Eclipse said the workspace I wanted to use was already in use.
So starting the VNC server on the main machine does not allow me to access the programs that are already running on the main machine under the native X server. However I can now do PHP debugging remotely using Eclipse + PDT now, and all the PHP source code is on the server machine. That's OK, but I would like to do more than that. I want to be able to connect to the native X server on my main machine, and control all the applications running on the main machine remotely from my laptop, without having to shut them down and restart them again via a VNC viewer.
Is there some sort of remote control program I can use to allow me to connect to the running X server on my main machine from my laptop, and control those applications remotely please, so the desktop layout on the main machine's screen is mirrored on the laptop screen?
I set up my first web server and it works flawlessly -when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.
I have two network interfaces on my server, eth0 (public static IP connected to internet directly) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1. It is connected directly to the internet and serves as a SNAT for other comps on the lan.I added "192.168.1.1 www_server_com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.HOwever, the server itself only opens website if the address islhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www_server_com ( I cant use dots as I do not have more than 15 posts on the forum )Here is the firewall script I am using.
I'm trying to access data from TFTP server which is running on my fedora 15, when i tried to read that file from TFTP path..i'm getting response as time out.. even i tried to get the data in localhost itself...there also i'm getting same time out.. i tried all permission mode.
In the past, I've installed Internet services as daemons and as xinetd.d with no problems. Those approaches do not meet my needs. And, perhaps, nothing will.
- the service was converted from VB-6 to wxPython. It has a GUI which is accessed with either "remote desktop" or VNC. - the wxPython service works on Windows and can be accessed from other hosts on my LAN - the wxPython service works on CentOS and Fedora, but can only be accessed from within the server host. Even from other user-ids. But, I cannot get to it from other hosts. - ipchains AKA firewall ports are marked for INPUT. - The server host uses autologin to fire up a useid in group "user". I do not want it running as "root". the .bash_profile fires the service up. - the service is heavily mult-threaded, and supports devices connected to serial ports asynchronously with the ephemeral port threads (all this works).
There are some programming solutions that I would rather not develop. - a proxy service that runs under xinetd.d. - separate the GUI code from the Internet and serial port code. Allocate a "control" port for remote GUI control. a'la SAMBA & SWAT
Is there any hope, that I can run it as is, by doing some network configuration stuff.
i installed unix services for windows 3.5 on a windows xp pro box and it installed fine. I configured nfs on the debian box and exported the ip of the client computer and forwarded port 2049 correctly. I followed the instructions for setting up teh nfs client on windows. However whenever i go to tools->map network drive and type in the server-domain-name:/file-address it says it cannot connect?
My office is on migrating to UNIX system. I am configuring Centos as our server including some program will be running on it. But one of the problem is we use foxpro for operating some program on server directly. I can run that program on Centos using DOSBox. My question is how can i run that program on winxp client that connected to network through samba to that program on server? so my plan is just give the shortcut and link it to server. I have tried to open it but not work.
I am a newbie to linux of 4 weeks. I set up my first web server and it works flawlessly - when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.I have two network interfaces on my server, eth0 (public static IP connected to internet) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1
I added "192.168.1.1 www.server.com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.
HOwever, the server itself only opens website if the address is localhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www.server.com.I do not understand why the record in etc/hosts doesn't point it in the right direction. It seems that when I open address 192.168.1.1 it still gets routed to the external network. I have seen using DNAT to deal with the problem but it didn't work in my case (maybe I didn't do it correctly). I have spent whole evening/night trying to sort it out, it's 4AM now, going to bed frustrated and angry (at myself hahaha). Still like linux very much, won't be going to windows anymore. Please help
My first time installing centos server and adding it to xp home network. I am new to setting up my own network in general. I have a home windows wired ethernet xp network (simple linxs router) with 2 xp boxes and one centos5 box all connected to the same router. I just set up the centos box running tomcat on port 8080. I need to do two very basic things at this point, but am not sure what I need to do:
What do I need to do so I can: 1. Connect in firefox on one of my xp boxes and call the tomcat server running on my centos box? 2. Be able to ftp to centos box from either of my xp boxes?
I'm trying to open up some ports to connect via vnc to a server running Centos 5.5. I've edited /etc/sysconfig/iptables everything *looks* fine, but I still can't seem to get access to the port I've opened (I added some newlines for clarity between commands):
I am at a loss. I can not access my work remote desktop via the terminal server client on my wired box running Ubuntu 10.10. My wireless laptop is able to connect right away once I established the VPN connection. The VPN connection is established on both boxes with no problems.
When I tried the Terminal Server Client on my wired boxed, it says it can not establish a connection. Yet my wireless box gets connected immediately!
I check the /etc/dhcp3/dhclient.conf and the /etc/resolv.conf to see if there were any differences, but they are essentially the same. When I have the vpnc connection, they both recognize it and I am able to ping the IP address shown when I do a "ifconfig" on the terminal.
What can be the problem? Anything I need to configure on a wired computer versus a wireless one? What else can I check?
I have been trying to install centos on my hp servers and when i get to partitions my hard drives the OS does not detect any harddrives. I have 4 scsi drives and i believe a intergrated smart array controller.
I installed Ubuntu 9.10 onto my laptop and then upgraded it to Ubuntu 10.4. I've added some software packages along the way, such as MythTV and several smaller apps, but have not gone crazy in adding apps. I have a 160GB hard drive.I ran out of disk space recording a World Cup game and was surprised. I deleted all of the MythTV recordings and ran Computer Janitor and now I have only about 50GB of free space! It is not my primary computer, so I don't have a bunch of videos, music, pr pictures on it.
I did a clean install of Ubuntu 10.4 to a USB flash drive and it has only 3.7GB occupied on the drive.Any recommendations of why I have over 100GB on the hard drive and any cures on how to clear out unneeded files?
I'm finally making the change away from rhythmbox for the now adopted Banshee and I'm noticing that my fans run really hard when I'm running banshee. I'm monitoring speeds and don't notice a huge increase in temp but the fans none the less run hard. CPU usage is running around 6% for banshee not nearly enough to cause this fairly large laptop so having the fans run hard make it a bit loud when around others
Hi. I have Ubuntu 10.04, nm-applet is running in the background, my battery icon and sound icon are showing but my network icon has been missing for the past 2 days. It was working fine before but now it's not. How can I fix this issue if I don't have an ethernet cord? Is there a way to roll back the recent updates or do I need to reinstall my network manager?
I've tried restarting the system and I've tried killing nm-applet and reloading it using Alt F2. I get some Debug error.
When I try to run nm-applet --sm-disable
It says an instance is already running and then gives me a warning.
I tried removing "iface eth0 inet dhcp" from /etc/network/interfaces and then tried restarting by "sudo /etc/initi.d/networking restart"
It says:
What can I do to connect to the internet? I have a flash stick if its possible to download a .deb package on this mac and transfer it over to my other laptop to fix the problem. If its possible.
I install Ubuntu from an installation of Ubuntu, rather than using the installation CD?Specifically, I have Ubuntu 10.04 installed (and bootable) on an SD card, and would like to install from Ubuntu (running on the SD card) to the netbook's hard drive.
