Fedora Servers :: Build A 3 Node Web Server Cluster To Run A Php Application ?

Feb 24, 2011

I need to build a 3 node web server cluster to run a php application. Since the app requires users to login (which means a session state is to be maintained), I will be sharing sessions save path, I also need to share the application directory across 3 nodes. I having trouble deciding which cluster file system to select.

Networking :: Port Based Routing For Local Traffic?

May 24, 2009

I have problem with port based routing for local traffic. I can't use trick with iptables -t mangle, ip route table 1, ip rule fwmark table 1 because it works only with forwarded packets. I can't even use patch-o-matic because it's obsolete. And xtables-addons doesn't contain support for "-j ROUTE" yet.

Fedora Servers :: Build A F12 Cluster To Run DHCP On Top Of Two Servers Using Pacemaker And Drbd?

Apr 28, 2010

I'm trying to build a Fedora 12 cluster to run DHCP on top of two servers using pacemaker and drbd. The pacemaker runs great but i'm having the hardest time getting DRBD installed.

My kernel version is First i tried to [root@dhcp-primary drbd]#yum install drbd this doesn't give me everything because apparently the kernel module for DRBD must be built from source. so i unpacked drbd-8.3.6.tar.gz and tried :


I'm not very experienced in compiling from source i'd love to make an rpm for this but after scouring the web and trying different install methods, I am still at a loss.

Programming :: Build All Project Dependencies On Fedora/RedHat-based Systems?

Sep 17, 2010

On Debian, if I want to compile some package X myself, but I don't want to spend time hunting down and installing its dependencies, I can issue the following command:

apt-get build-dep X

And apt (so long as it knows about package X) will install all the dependencies for me.Does the yum package manager on RedHat-based systems have a similar feature?

Ubuntu Networking :: Can See All Devices On Local Network And Their Local Ip Addresses

May 16, 2010

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

Ubuntu Networking :: Unable To See Local Web Sites From Local Network

Jun 28, 2011

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page ( is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

Server :: Build A 2 Node Failover Nfs Cluster?

Feb 9, 2011

I am using Centos. I have read places that you can use Drbd + heartbeat + nfs to make a simple failover NFS server.I can't find any document that works though. I've tried 20 or so, including some Debian ones.So, does anyone have any other ideas of how to do this?Point me in the right direction please.I want 2 nodes. One to be actively serving an NFS share The other to be ready for failover. If the first one goes out, the second takes over.Meaning, the filesystem is in sync, the IP must change, and NFS must come up

Fedora Networking :: Networkmanager Can See My Local Wireless Network - Asks For The Wep Key

Sep 26, 2009

I've spent AGES getting ndiswrapper to work on FC11 with my USR 5416 card.

Now it's finally working and Networkmanager can see my local wireless network. Problem is when I try to connect and it asks for the wep key, the encryption I'm using is not an option.

My network uses a 64 bit ASCII passphrase. My options when connecting are:

None of these seem to be right for my network and, consequently, none of them work.

Ubuntu Networking :: Use Local IP Only On Local Network?

May 25, 2010

I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.

However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.

Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?

Server :: 2 Tier File Synchronization (block Based, Possibly Cluster FS)

Oct 25, 2010

I'm looking for a write one, read many file synchronization, file system or similar technique. In fact I want a to imitate a zfs_send/zfs_receive similar behaviour on Linux. My requirements are pure local (or in terms of distributed file systems: rack-aware) file handling with remote synchronization. Some random features/requirements I want to achieve are (I use the terms file and "file system" here interchangeable, as I don't care wheter I have to synchronize file based or use full file system supporting that):
Access on files from a specific host is pure local, i.e. the node has a full copy of a file, no parts are distributed. Read and write access is local, the remote side gets synchronized with write changes only Write changes on the remote side are non-blocking and asynchronous No need for concurrent file access, concurrent, distributed locking and so on Every file is changed by a single node only, other nodes have read access The file "owner", thus the node allowed to write files must be changeable Similar techniques (some as technology concept, not usable for me) exist, among those DRBD, MySQL Replication or even pure rsync.

I don't care whether I'm referring to a pure local solution (i.e. between two block devices) or a client/server mode. DRBD won't fit because its a peer to peer solution, I need to synchronize a lot of clients with a central storage through that way where DRBD just mirrors from peer to peer among two nodes and doesn't allow another node to take over the role of the primary node (i.e. node A is master, storage B secondary, I want to change to a thrid node C which becomes master and receives hence a full update from storage B.

Just as a guess, I'd make a local LVM volume on every node where write access happens. In the same time there exists a iSCSI target with multipath to a remote hosts which is shared with every node, again providing a clustered LVM. So I'd need to synchronize a local LVM volume with a remote LVM image. The question is just by which technique I could achieve that (i.e. as RAID 0, where every read and write goes to one node only and doesn't wait the other node to succeed). I could achieve this with rsync by a cyclic push to the remote host, but the problem is, that rsync isn't block based thus I'd need to synchronize every time the whole file, not only changes.

Fedora Servers :: How To Setup GFS2 Without Cluster Suite / How To Configure Cluster.conf

Nov 6, 2010

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

Can anyone enlightened me on what should I be doing so that I could "bump" the cluster config version?

OpenSUSE Network :: Cannot Resolve Host Names On Local Network?

Mar 9, 2010

I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!

This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.

Networking :: Creating Simultaneous Network Connections To A VPN And Local Area Network?

May 31, 2010

I'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:


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.

Networking :: Routing To Internet Through One Network And To Local Ips In Another Network?

Mar 31, 2009

I have two networks. One of them is wired, the other is wireless. The wired has an internet connection and a few other computers connected to it. The wireless network has a few hosts connected to it too, but it has no internet connection. What I've been trying, fruitlessly, to do, is make all connections that are bound to the internet, or my wired network, be routed that way, and all the connections to the hosts of the wireless network go that way.

Here's the setup..

Wired: Gateway =

Route internet through here

Wireless Gateway =

If my computer sends a packet to the internet, it should be routed through If I send a packet to one of the local hosts of the wireless network, it should be routed through Here's the routing table I've set up(This is one of many configurations I've tried)


$ ip route show dev wlan0 scope link via dev wlan0 src


With this, and everything else, I get destination host unreachable when pinging. The strange thing is that, if I unplug my eth cable, reboot and connect to the wireless network, everything is fine and I can access the router and the others. I'm trying to improve my networking skills, as I've had this of setting up a small linux box as a router for quite some time, for the fun of it, but I need to get routing under control before I go ruin my network.

Fedora :: Change That Network To A Based Network?

Apr 12, 2010

I've been running Fedora on my Laptop (Dell Precision) for 1.5 years. I have a Windows based network. What I'd like to do now is to change that network to a Linux (Fedora) based network. Its got 4 workstations and a switch ... I don't want internet access to this network, ... just to be able to share files between the PCs. In windows it was a matter of specifying different IPs and same workgroup assignments to each node. How does it work in Fedora ?I'd also like to see Peer-to-Peer work between my Laptop and my friend's Acer laptop running (Fedora too).

Fedora Networking :: Can't Export NFS In 9 X64 Virtual Cluster

May 2, 2009

I'm trying to get experience in creation of virtual Fedora 9 x64 cluster using Ubuntu 9.04/Virtual Box 2.2.2. I have a head node with 1 G of RAM and two slave nodes with 512 M each. There's internal networking in Virtual Box with DHCP, so my nodes have addresses: (Slave0.localdomain), (Slave1.localdomain), (Head.localdomain). Ping is OK. I've added the following string to /etc/exports file: /usr/share And then used /usr/sbin/exportfs -a But showmount -e entered at slave node shows nothing. What's wrong? May be I have to somehow start nfsserver, but how?

Networking :: Build Fast Home Network With Domains And Workgroups?

Jan 4, 2010

At home we have a small home network, but it is very slow. I believe it is, because some computers are placed in a workgroup, called WORKGROUP and others are placed in a domain called TUE. The domain is because many of the laptops at our house also have to work on our university, and I can't simply put them in a workgroup.

The reason why I believe it is slow because of this, is because file sharing between the computers in the workgroup goes with 5 MB/s. File sharing between a domain computer and a workgroup computer goes as fast as 160 KB/s. This is the upload speed of our internet here. How to make the connection with the domain computers the same speed as the workgroup computers? I can not simply put the domain computers out of their domain and in the workgroup (as explained before)

Our network looks as follows:

General :: How To Build Distribution Based On Ubuntu / Debian / Mint Easily

Aug 26, 2011

Is there a tool or tutorial to build a distro based on mint/ubuntu/debian?Git, scripts, and tools, small compilations for branding are OK. Compiling kernel, x11, gnome, compiz, etc. is BAD unless really required. Specifically, I'm looking for a way to have some applications installed by default, change logos/about boxes, change theme, configure what compiz options are, and add firmware drivers (connect to the Internet to download wireless adapter driver? <- headache, gotta find a lan cable now ...), and still have the liveCD install method. I'd like it to be based on linux mint, but I only want a few tools from it (update manager, software manager, flash, media codecs), so it's ok if it's ubuntu/debian with those mint tools added back in.

I saw some options, too complex, and others too simple. Not looking for a "learning experience" like LFS which gives me a horrible linux build if I don't do something exactly right. Nor any of those tools which are just package pickers and don't do enough. suse studio looked about right(maybe tad too easy), but was RPM based, not deb based.

Networking :: What TLD To Use For Local Network

Mar 29, 2010

As it looks like the number of DNS Top Level Domains are just going to proliferate in the near future, use locally on an RFC 1918 private network in order to prevent a future name collision issue?

.local is the most obvious one but as that was stolen by Apple for mDNS/rendezvous use it's probably wise to avoid it now.
