Networking :: Assigning Process To Use Specific Nic
Apr 19, 2010
I want to be able to tell processes/programs somehow to use a specific nic. I have a laptop (used as dekstop) and want to make pidgin use my wireless. I have a gigabit wired connection and a wireless connection. I want to force pidgin to use the wireless connection. But more specifically, I just want to block pidgin from using eth0... how to go about that? I can't find anything that will block applications... I could block outside servers from communicating with eth0, but I don't want to do that.
This is a long shot but I'm looking for a way to assign an IP to a specific location or process. I'm running a server for a small indie game that I liked, I intend on running as many gameservers as possible from this server, however I hit a problem: The game limits servers to 4 per IP address, after this the servers no longer are able to connect to the main server and therefore be used. My server has enough IPs to run many gameservers, but I'm unable to work this out.
I need to assign either an IP address to a process or folder, right now I have it set up like so: (assuming 1.1.1.1 = server IP)
/gameservers/server1/program < assigned to 1.1.1.1 /gameservers/server2/program < assigned to 1.1.1.1 /gameservers/server3/program < assigned to 1.1.1.1 /gameservers/server4/program < assigned to 1.1.1.1
[Code]....
I do not have access to modifying the core program, it runs in Java. How would I go about doing this, if indeed possible? I need to either apply the selected IP to a folder or process without changing the actual program.
I got this definition:"a process that replaces a series of related, specific routes in a route table with a more generic route." honestly I found it not so clear.. I want to know if this definition is correct and also more details about this subject..
I have to do a project on network security.For that i have to capture the packets from the device. I installed libpcap tool in ubuntu. If I give ifconfig -a it lists out eth0, wlan0, lo. I am able to connect to the internet via eth0. But when I give
#include <stdio.h> #include <pcap.h> int main() { char *dev, errbuf[PCAP_ERRBUF_SIZE];
[Code]...
It says device is null. I'm not able to run sniffex.c program also. All I want to do is to capture the live network level packets and analyse them.
Just completed installing Xubuntu 9.04 to my old Dell Latitude CPi and it seems to be working quite well. However I need to assign interface eth0 to my pcmcia network card (as opposed to eth1 or eth2). I have two cards to try out. One of them comes up as eth1 and the other as eth2. There is no eth0 listed when I run ifconfig -a. There is no built-in network cards on the laptop, so I don't know why it won't assign eth0 to either of the cards.
how to assign eth0 to either of the two PCMCIA network cards.
I've written a program for a class that my professor will be testing in various low memory environments to see how it behaves when the program runs out of memory. Is there a way I can simulate the execution in a low memory environment without creating a virtual machine?
On my RHEL5 system one of my key file in one specific directory gets deleted when I start my application suite (having multiple processes). Is there some way to narrow down which specific process is deleting this file?
I want to change the resource limits for a specific processOr to create a new process and give it limits as I want, There is a function setrlimit, Which is possible to change it but for a programmatic I want to apply it to another Process, The problem is that this function does not receive process ID for example. I read in most books on the subject of The Linux system programming
and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...
This works perfectly, however when I try to add a second client this way it doesnt. I tried to add the above code multiple times as a whole (2 times the above code) but that doesnt work. I also tried to just add more lines under host apex but this also doesnt work.
So my question is: How do I add more of this mac related IP adress assignments in the dhcp.conf?
Is there a way to bind specific programs to specific network devices (not IPs, since I have dynamic IPs)?
For example, I wish for irssi to route through eth0 and w3m to route through eth1. Keep in mind these devices have dynamic IPs, so I cannot attached them to an IP.
The solution cannot be accomplished through route since route pivots on IPs not devices.
I have two onboard gigabit Ethernet ports and 3 10Gb add-in fiber ports. When everything is cabled but nothing is IP'ed yet, I do an ifconfig -a and the two gigabit ports are showing as "__tmp2143330114" and "__tmp1076785124", eth0, eth1 and eth3 show as the 10Gb addin cards. On other (identical) servers, eth0 and eth1 are always the gigabit ports and eth2, 3, and 4 are the 10Gb ports. Anyone know what is going on?How can I make sure that Red Hat detects and assigns these ports correctly on boot, or at least can I reassign what ports are designated eth0-eth4?
I want to make make my fedora machine access-able over the internet. I want to assign IPV4 address to this machine( I already have one IP address ) which can be used for this. What configuration changes I need to make in fedora to make it accessable to the external world
I'm trying to find how to schedule a process to start at a specific time (not on start up). How would I schedule a process/application to start at a specific time (if it matters, it will be a background process). For instance, have process abc start every weekday at 5am. I've done this for windows many times though have only been using linux regularly for a few months and haven't figured out the best way of doing this.
So far the best solution I have is to create a program that will start on boot and have it check the time and sleep until the required time and then start the required process(es) at the required time(s). But this seems more of a hack since I'd expect there to be a proper way of doing this.
I just had an ATT Uverse RG installed. However my Smoothwall router that previously worked fine with the ADSL SpeedStream is no longer accepting an address assignment DHCP ip address from this new gateway. (3800HGV-B)Any thoughts ideas or experience working with this hardware? ATT only supports Windows and Mac
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
I need to search a bunch of files in a specific folder for a specific number and add all the numbers together to a total sum. I use Rsync everyday, everytime I run rsync i get a logfile (rsync output) witch contains the textstring "Total bytes sent: xxxxxx".
The "xxxxx" can vary in lenght. I need to extract the "xxxxxx" from each file and add the numbers together to a total size over a week or a month. Is this possible? And I wish to only use bash. One way of doing stuff at a time my friends .
my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.
I'm trying to mount a USB key in a RHEL5 box to upload some file. I found doc online and followed it and mounted it fine the first time. Then I unplugged it and found that I have another file to upload so I plugged it back in. However this time it's not assigned a partition (last time was sdb1) and I can't mount it anymore. I think the USB key is recognized and the driver is installed properly:
I'm using Debian kernel 2.6.32-5-amd64 I have this little nit picky problem when I re-boot, my webcam and my Tv card switch around on video0, video1 and video2 if my usb webcam is plugged in at boot. I would like to keep it plugged in all the time and have it on video2 and my TV card on video0 and video1. I had read where maybe setting up a udev rule might accomplish what I want to do I just don't understand how.

I am able to connect to wlan0 in SSH to address 192.168.1.200, and I also receive requests when ping 192.168.1.200 from a windows machine. How can I use a different subnet for my wlan0 iface...
I am using linux mint and have installed Netbeans on it but whenever I run netbeans from accounts other than root it throws an error for not having permission to start glassfish server of netbeans. I also tried running this application using run as administrator option but then the application does not start.
So is there a way to assign netbeans admin rights permanently so that whenever I start this application from other accounts I should not face this error?
