Fedora Networking :: Multiple IP On Single NIC?
Jan 23, 2011
I've been trying to set multiple IP my Fedora 14 but nothing seems to work. Upon browsing the net, I found there are two ways for it. One is eth0:0~eth0:n nd another is eth0-range0. All are configs under network-scripts. But neither of them worked for me. Even grabbing a working example from my live server doesn't do the trick (though the server is a CentOS 5.5).
Currently using eth0-range0
ONBOOT=yes
IPADDR_START=192.168.1.127
[code]...

I have question about the UNIX sockets. my goal is to connect multiple sockets from a single client to a single server and keep them open...I'm not sure if that is possible to create or not. Do you have any suggestion or an example of code?

I've got a co-worker who is trying to connect multiple devices to his wireless router - Xbox, Wii, TV, Dishnetwork box, etc. Not all of the devices are wireless however. He's had several thoughts on how to get this done and I know very little about this kind of thing so I thought I'd ask some of you.
His first thought was to buy a multi port bridge, but he doesn't like any of the ones he's seen so far.The other thought was to connect all of the devices to a switch and then use a single bridge, but he isn't sure if this would work.

I know a fair amount about setting up a simple network but I'm curious about setting up a more complex topology...For example...A "box" has two NIC's acting as a bridge, normally this would involve two distinct networks (ie. 192.213... and 192.214...) is it possible that this physical set up can create a single network (192.213... 192.213...) resolving IP's from either a DCHP on the "box" or a DCHP server somewhere else on "one side of the box"likewise with differing physical network types, a "box" with a NIC and a TCP/IP over usb setup connected to another device with TCP/IP over usb (OTG/Gadget) so that all the IP's are on one logical network.

I am find myself in need of building what amounts to 3 ip networks on 1 physical lan.
first LAN is another companies network on the 10.0.0.0 network a mix of pc's and equipment
second is LAN new company network 192.168.168.0/24
third network is an ip phone system for both i would like to use 192.168.200.0/24
i am hoping to use the same dhcp server to do this, assigning address to the old company's 10. network via mac address reservation.

Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".

is there an app, runs in Fedora, with a GUI, that can join multiple mp3s into a large single file?
I know Audacity can do this, but it's not really suitable for multiple files and I have voice notes that are in 10 minute chunks.

I recently installed Ubuntu Server 9.10 with the intent of using it as a platform for running a couple of Windows XP virtual machines along with Linux/Ubuntu.
I had no problems getting the server installed. Had no problems getting the network up and running so that I had access to both my internal network as well as external connectivity to the internet. Had no problems getting a VM installed and putting Windows XP inside of it. Had no problems setting up a bridge between the WinXP virtual machine and the physical ethernet card (eth0).
What Im having trouble with is figuring out how to bridge from multiple VMs AND Ubuntu natively through one physical ethernet card.
When I set up the bridge, it knocks out the static IP address of the ethernet card that was set up initially with Ubuntu when first installed before the VM was created and installed. Therefore, connectivity within Ubuntu natively is lost.
Similarly, am having trouble figuring out how the second VM (also going to be running WinXP) is going to get its connectivity since it doesnt seem to like me setting up 2 bridges to the same physical ethernet interface card.
I need all 3 machines to have static IP addresses and be visible/accessible from the external network for either web/mail/dns/etc servers on the Ubuntu side and for remote PC control functionality on the VM side.
I have tried setting up alias ethernet interfaces (eth0:1, eth0:2, eth0:3) with static addresses which work fine from native Ubuntu in presenting multiple IP addressees, but it seems that Im not permitted to bridge to these alias interfaces.

My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. Do you have any idea what open source solution i can apply for my problem?
I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.

I have an Ubuntu install on an 8Gb SDHC Card, customized for my Toshiba NB205. It took quite a bit to get sound and BT working, but now it's fine. Just out of curiousity, I used this same SDHC Card to boot my Dell D610 -- it booted, and sound and WiFi worked fine. I was surprised. There was a single error message after the desktop appeared, but I didn't record it.
I am now wondering: is it practical to use a single USB installation with multiple devices? I can imagine a number of complications, but was surprised that my attempt worked on two very different hardware platforms. There was discussion, when pendrives first appeared, of being able to use one to boot any PC to your own USB-based OS, bypassing any other OS installed on the PC.

Is there any limitation to the number of transactions through a single port if so then if we assign multiple port to that particular service then the performance is increased (what i suppose)
so: Is there any way to assign multiple Ports to a single service. like for a web server the main service is httpd or some thing like that to be running on the server and now if we assign multiple ports to that service then the performance increases.

We have too many audio Paths, for each user have one. We would like to create a unique folder to Read in network.
For example:
The idea is Mapping all folders to the path /pub/Music in server, so all user can access all music online in the server.
Very Well. How we can do it?
And when pc1 and pc2 have the same subfolder, like Beatles, and in the subfolder have different folders ( PC1-Beatles/Revolver ) (PC2-Beatles/Habbey_Road) or The same folder (PC1-Beatles/The_Mistery_Magic_Tour) (PC3-Beatles/The_Mistery_Magic_Tour)...
Is there a way to contemplate this issue?

I'm using my home server to netboot into live CDs. To summarize that article, netbooting a liveCD system involves passing an NFS host:/path in kernel's command line, which is subsequently mounted as /cdrom on the live system. The article mentions copying the contents of the iso image to a place on the hard drive, but I see no reason for this, since the contents need to be read-only anyway, which is easy to achieve by mounting the iso through a loop device:
Code:
# mount
...
/dev/loop0 on /mnt/kubuntu-lucid-amd64 type iso9660 (ro)
/dev/loop1 on /mnt/kubuntu-natty-amd64 type iso9660 (ro)
[code]....
Now, I am using NFS to mount a regular (rw, HDD) directory which I use as a network drive and I can mount any subdirectory and still access all the files within, ie. when I export /data on the server, I can still mount /data/downloads on the client:
Code:
server:# exportfs
/data 192.168.1.4/32
client:$ sudo mount -t nfs 192.168.1.1:/data/downloads /mnt/netshare
[code]....
Is it possible to export just /mnt and be able to mount any/all of the subdirectories? NFS doesn't like going across multiple file systems:
Code:
server:# ls -al /mnt/kubuntu-natty-i386/
total 3532
dr-xr-xr-x 11 root root 4096 2011-04-27 11:29 .
drwxr-xr-x 7 root root 4096 2011-07-25 21:46 ..
[code].....
When I try to export just /mnt and mount /mnt/kubuntu-natty-i386 on the client, the mount succeeds but the mounted directory is empty.

I am using DVD::rip to convert some instructional DVD's to .avi (xvid + mp3). I have never used this app before but its seems fairly straight forward and easy to use. I am able to convert 1 title from the DVD to 1 avi file. One DVD however has 19 titles which vary from 3-5 minutes in length. My question is, can I convert all or at least some titles to a single .avi file and if so how?

I need to transpose a file with over a 1000 rows of 5 columns of numbers into a file with a single column of numbers. The numbers are separated by a single space and range from one digit to 5 digits each. I tried using awk, but can only get it to grab one column of numbers.
Input:
1 2 3 4 50
600 7 8 9000 10
11 12000 13 14 15
Desired output:
1
2
3
4
[code]....
Tried using: awk '{split($0,a,""); print $NF}' <filename> and got:
50
10
15
It only grabbed the last number in each row.

I am looking at setting up a multiple postfix SMTP servers for a single domain. Below is my requirement, I would appreciate if someone out there could guide me to achieve this using postfix..
1. Want to setup 2 postfix SMTP Server with 1 POP3 Server.
2. Server1 will host POP3 & SMTP services for domain "metallica.one".(IP: 1.1.1.1, MX: mx1.metallica.one)
3. Server2 will host only SMTP services for domain "metallica.one" (IP: 1.1.1.2, MX: mx2.metallica.one)
4. Server1 & Server2 will be used as load balancing for sending mails. (either manual settings in email client, or auto-loadbalancing is still preferred).
5. Mail received for domain metallica.one on Server2 should be pushed/forwarded/relayed to Server1 where POP3 services are running.
6. Outgoing mails for other domains from Server2 should be sent directly to the other-domain-recipients without relaying to Server1.

I have configured a file server with samba and winbind in RHEL5.I am able to allot permission for the active directory groups to my Linux folder.No issues.But i want to set multiple groups of active directory to get ownership to a single directory. Say there are 3 groups a,b,c to have permissions to a folder of the Linux machine.
Code:
chown -R root:Active_directory_group_name path_to_linux directory
I have set
Code:
chmod 770 /myshare
meaning that user and group would have full rights to /myshare
Code:
chown root:a
works great I tried with the option of
Code:
chown -R --reference=/etc/shares_own.txt /myshare
In reference file(shares_own.txt) i gave the entry as
Code:
root:a,b,c
This is not working.

I am having a problem with apache's virtualhost directive hosting multiple domains on a single IP with Apache 2.2 on Fedora 11. For example i have domaina.com and domainab.com pointing to the same IP address and have my httpd.conf configured like so:
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /www/domainA
[code]....
The problem is when i navigate to either domaina.com or domainb.com i get the default Apache page. Its like it is only accepting the default DocumentRoot directive.
