Wondering if the internal network will benefit of connecting to a local DNS server, rather than my ISP dns server. Can I create this local DNS server, without having an external domain, pointing to my server ?
All I want is faster lookup of known hostnames, both internally (hostnames) and externaly (cnn.com etc..)
I am installing a cluster which is hidden from the rest of the world and there is no router either froma general login node. I would therefore require a local repository of the updates to CentOS5.4. When I checked I only found instructions for a full mirror. As I have no room and neither the human resources to setup and maintain a full-blown mirror, this is not a solution. However if I try to find updates for 5.4 to download in a repository-type of way I fail to find a solution. Maybe I am just not looking in the right places.
View 1 Replies View RelatedI'm setting up my server under CentOS 5.5 (text mode) and I installed cherokee server but I couldn't reach it with the ip given by ifconfig. So I figured it might be an problem within cherokee. I also wanted to install webmin so I did that to see if I could reach that one. But also the webmin server is not reachable (I know the port number should be behind the ip ). So if I look up ifconfig I see the server has got an local ip (192.168.1.42) but I can't reach it from another computer in the same local network.

View 1 Replies View RelatedI'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

I am now trying to setup a VSFTP server where local users can upload files to there home directory so that Apache can serve web pages straight from the directories of system user home/accounts giving users the ability to run their own web sites which are hosted off the main server [tutorial here: [url]
So far i have been able to serve/display index.html files from the users home directory [url] but so far i cant upload files to any user home directory, every time i try to upload a file with filezilla i get this error message: 553 Could not create file. Critical file transfer error
I have searched online for similar problems like mine and so far i've tried alot of the solution but none seem to work. I'm confused, dont know where i went wrong, i put the users in a group called ftpusers and here are the permissions on the users (test, ftpuser & testftp) home directory. have a look an tell me where i went wrong :(
Also the root directory where the web pages are served from is called public_html here are the permissions
Here is my vsftp.conf file can someone check it to see if i made any errors in there:

View 1 Replies View RelatedI am new to linux, running a brand new centos 5.2 server. One application I want to use it for is to serve as a network host for a game my friends and I enjoy. Normally, to run the game in host mode you call the binary and pass it a port number (along with other options). To host a second instance of the game, same thing different port, you get the idea.
After doing that the binary runs in your window and dumps to stdout, so if you want it to run 24/7 you have to come up with your own strategy like nohup. Fair enough, now, I'm trying to coax the game into restarting automatically upon reboot. The most correct way to do this seemed to be to write a script for init.d so that's the road I traveled down. Now, to strain the metaphor, the pavement has ended and I'm stuck in the sand.
Here begin my questions:
I've been following the structure of other init.d scripts and I notice they all seem to call the function daemon() (contained in /etc/init.d/functions) to start their services. Looking at the structure of daemon() I see that you can pass it a user and a pidfile. The user part seems to work fine, but no pidfile is created. Let me be more specific.
Like the other scripts, I explicitly touch /var/lock/subsys/game-port on startup, which works fine. However, all of those other services seem to have a pidfile in /var/run and mine doesn't. They don't create it explicitly in their init.d script therefore I assume that some other process is creating the pidfile. At first I thought it would be the call to daemon(), since you have the option of passing it --pidfile, but that doesn't seem to work.
Are the services themselves creating the pidfile? If that's the case then I have more complications because the game binary apparently doesn't do this. Second question but probably related to the first. None of the other init.d scripts I looked at seem to do anything special to detach their services from a particular terminal session, therefore I didn't think that I would need to either.
Again I thought this was something the call to daemon() might accomplish, but either I'm wrong or I'm doing something wrong. I can probably work around this with nohup or appending '&' or something, but I'm just curious that other services like crond, sshd, named, etc., don't seem to do this. Are they determining this behavior from within the binaries themselves? I hope this is clear, as I said I'm new so I may not be getting all of the terminology correct.
I've been looking for a good tutorial for setting up a BIND DNS server for my local network.

View 2 Replies View RelatedI'm in the process of creating local repos for our company servers (CentOS 5.5) and laptops (Fedora 13). And while the CentOS part went perfect the Fedora part is causing major trouble.But first things first, here's the setup: a central CentOS 5.5 server is running Apache2 and has a VirtualHost listening on Port 8080 for both CentOS and Fedora. The DocumentRoot for this VirtualHost is /data/repo wherein two directories, centos and fedora, reside.

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

I can ssh from my laptops but it will not open the apache startup page.
View 1 Replies View RelatedI have recently installed Fedora 12 on a desktop PC and as my first experience of Linux, I am really impressed. I have now installed several packages and have reached a point where I would like to share the PC with other user (family members in the same house).My question seems so basic I am almost embarrassed to ask it but could some one explain the best way to create a local shared directory that could be used to store files accessible to everyone (e.g. music, photos, videos, documents etc.)There will be three users and as it is a family PC, they will all have full access.
Reading posts from various forums, I am little confused about what is the best way to proceed (i.e. what is Linux best practice). The simpler of the two methods is to simply make the directory using the mkdir command, followed by the chmod command to assign full access rights. Fore example if the local shared directory is called 'share'. The alternative approach assigns a group, a group administrator etc and then adds users to the group.
i am using Fedora 12. How can i download the entire repository of fedora(fedora-release, Rpmfusion)..?
what will be the size of the respository??
