  Setting up a simple NFS server
Posted by: xDamox - 2005-09-06, 05:25 PM - Forum: Samba and NFS - Replies (1)


In this guide I will show you how to setup a simple NFS server using Fedora, but I will show how to set it up via command line so you should be able to configure it on more than one distribution.

 

The first step is to make sure you have the NFS server software installed you can check this

by issuing the following command:

 



Code:
rpm -q nfs-utils




 

if you don't have this package installed, you can use the YUM packages management tool to install the package, to do this issue the following command:

 



Code:
yum install nfs-utils




 

Once you have installed the package you can begin to configure the NFS server, you should have

a file in the /etc directory called: "exports". This file determines what directory's will be exported, who

is allowed to access them and what permissions they have.

 

In this tutorial I will be exporting my /home directory and allowing only the IP of 192.168.0.13 to

access this exported directory. So the first step is to edit the exports file and added the following:

 



Code:
/home 192.168.0.13(rw,nohide)




 

The above exports the /home directory with the read and write permissions the attributes

inside the brackets can be read using the man command along with other attributes that can go in the brackets:

 



Code:
man exports




 

Once you have setup your export you should start the portmap daemon. The portmap daemon MUST always be running when running a NFS server.

 



Code:
service portmap start




 

Once your portmap has been started you can start your NFS server:

 



Code:
service nfs start




 

Once the service has started you can check everything is running by issue the following

command:

 



Code:
rpcinfo -p




 

You will get output similar to:

 



Code:
  program vers proto   port
   100000    2   tcp    111  portmapper
   100000    2   udp    111  portmapper
   100003    2   udp   2049  nfs
   100003    3   udp   2049  nfs
   100003    4   udp   2049  nfs
   100003    2   tcp   2049  nfs
   100003    3   tcp   2049  nfs
   100003    4   tcp   2049  nfs
   100021    1   udp  32833  nlockmgr
   100021    3   udp  32833  nlockmgr
   100021    4   udp  32833  nlockmgr
   100021    1   tcp  32774  nlockmgr
   100021    3   tcp  32774  nlockmgr
   100021    4   tcp  32774  nlockmgr
   100011    1   udp    704  rquotad
   100011    2   udp    704  rquotad
   100011    1   tcp    707  rquotad
   100011    2   tcp    707  rquotad
   100005    1   udp    706  mountd
   100005    1   tcp    709  mountd
   100005    2   udp    706  mountd
   100005    2   tcp    709  mountd
   100005    3   udp    706  mountd
   100005    3   tcp    709  mountd




 

Once everything is checked out and the services are running you can connect form 192.168.0.13 and mount the /home directory.

 



Code:
mount 192.168.0.2:/home /mnt/home




 

Replace 192.168.0.2 with your NFS servers IP and the /mnt/home mount point to one that

suites you.

 

if you make any changes to the export file you will need to reexport it instead of restarting the

services issue the following:

 



Code:
exportfs -r




 

well you can now setup a simple NFS server and store your files on the server :)

  site uptime, kernel uptime reset itself.
Posted by: anyweb - 2005-09-06, 02:27 PM - Forum: Site News - Replies (7)


hi guys

 

according to

Quote:[root@www root]# w 16:21:03  up 21:10,  3 users,  load average: 0.04, 0.04, 0.00
the site is up only a few hours, which to me is rather annoying.... 

I didn't reboot it, further examination revealed that all logs are OK and not one of them mentions a reboot or crash, indeed not only that but ifconfig shows data throughput that just 'doesnt happen' on linux-noob.com in 21 hours....

 

Quote:[root@www root]# ifconfig eth0eth0      Link encap:Ethernet  HWaddr 00:B0:D0:88:FF:78

          inet addr:100.0.0.3  Bcast:100.0.255.255  Mask:255.255.0.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          Interrupt:10 Base address:0xfc00
 

ok then, so what is happening here ?

 

well according to this site the uptime changed after a certain number of days/hours

 

[/url]http://en.uptime-project.net/page.php?page...ofile&uid=60313

 

Quote:1. 26.04.2004 14:42 GMT  05.09.2005 16:21 GMT  1y 132d 01h 38m 07s  Linux 2.4.22-1.2188.nptl
 

and we all know that there are 365 days or so in the year, and 365+132 =497 days....

 

well guess what. the above linux kernel (fedora) was unpatched for a uptime overflow after 497 days, so the server did NOT reboot, but the uptime WAS RESET by a bug in the kernel.

 

[url=https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97373]https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97373

 

if only i knew before it 'reset' itself.

 

dam annoying and i'd like to announce this post so that others may be aware in the future.

 

cheers

  vpn
Posted by: freagel - 2005-09-01, 12:05 PM - Forum: Network Problems - No Replies


I have a D-link router connected to a LAN where we need to use vpn.

I have two computers (debian and windows XP) connected to the router, both are able to set up a vpn-tunnel. The problem is when I set up one vpn connection from my debian machine, and another vpn connection from windows XP, that everything works but very slowly (400B/s wher a "normal connection should deliver 800kB/s) in the beginning and stops working after 2-3 minutes.

 

What did I do wrong?

Do I need to let my router making the vpn connection?

Is this possible?

 

Thx in advance

  resolv.conf is overwritten on reboot
Posted by: znx - 2005-08-31, 09:19 PM - Forum: Network Problems - Replies (2)


Just a quick tip:

 

For those using DHCP clients, you will proably find that on reboots that your resolv.conf is overwritten. To stop this from happening you can:

 

 

For dhcpcd its easy, add the option -R to your command line:



Code:
# dhcpcd -R




 

You will need to find the configuration file to edit and add this option to (differs per distro).

 

For dhcp-client there is a couple of options, the best, imho is to create a file "/etc/dhcp-enter-hooks":



Code:
# /etc/dhclient-enter-hooks

make_resolv_conf() {
     echo "doing nothing to resolv.conf"
}




 

 

Thats it... have fun,..

  Cannot turn sound volume up....
Posted by: JSuperKitten - 2005-08-31, 01:32 PM - Forum: Audio and Video - Replies (3)


Hi,

 

i have recently installed RedHat 9.0 (kernel 2.4.20-8) on my PC. So far, everything works great only i could not say that much when it comes to playing cd's.

I have a Sound Blaster Live card, which the system could still not detect. Still i am able to play cd's

Only i cannot seem to find where i may turn the sound volume up. I mean turning the volume up in KSCD is fine, however i have to turn up the volume of my speakers to almost the maximum in order to hear cd's.

Thus i have been searching every possible sound configuration program within KDE and failed to succeed in restoring volume to a proper level.

Isn't there some type of equivalent to the Windows>Control Panel>Sound Configuration in KDE?

or else a command that could possibly interact with the system's sound controls?

 

thank you,

JSK
