for providing an earlier solution from which I have modified and butchered the below script.The intended purpose of this script is to take a subnet mask for example 255.255.255.0 and turn it into the corresponding wildcard mask value in this case it would be /24I have got to the point where I have the binary value, the script is

The related services must be restarted automatically for the new IP Address and Subnet Mask to take effect. No user name and password should be asked for when using that Web Interface.

View 10 Replies View RelatedI am using ubuntu Lucid and connected to a network with windows machines.Our network admin changed some settings in the network, and all machines need to change their subnet masks to access local machines (e.g. I am getting "unable to mount" message when I try to connect other Windows PC's on the network.)
If I open the connections panel, and "Edit" the "Auto eth0", I can get: IPv4 Settings -> Method -> Manual -> Addresses -> Add .And I am pretty sure I will put new subnet mask address into "Netmask" box, what to put others? Namely:
IP Address, Netmask, Gateway and below:
DNS Servers, Search Domains
I can get some info about my network connection by right clicking network icon on the panel, and select "Connection Information" Tried to fill manual settings with some of those info (the ones made some sense to me) but I still cannot mount windows network drives, plus my internet connection dies.So, is there any way to change Subnet Mask "ONLY", without touching any other setting.

I have TWO L3 + router switch (say switch1 and switch2). I created VLAN100 with VLAN ID 100 in both the switches. I created router 192.168.1.1/24 in Switch1. I created router 192.168.2.1/24 in Switch2. Switch1 is connected with 1.x/24 PCs. PCs are configured with 1.1 gateway. Switch2 is connected with 2.x/24 PCs. PCs are configured with 2.1 gateway. Both Switch1 and switch2 are connected by a trunk to carry VLAN100 data.
1)I have few PCs of 1.x connected to say Switch1 Is it possible for PC with IP 192.168.1.100(x) to ping PC with IP 192.168.2.100(y)?What are the configuration required in both switches to make them communicate ? All the device in both the subnets should ping/communicate with each other.
2)Move PC (192.168.1.100) to switch2. Move PC (192.168.2.100)to switch1.What will happen when PC(1.100) ping (2.100) and vice versa?What will happen when PC(say 1.80 in switch1) pings PC (say 1.100 in switch2) and vice versa? What will happen when PC(say 1.80 in switch1) pings PC (say 2.100 in switch1) and vice versa?
Is there any Linux tool that will take a SWF file and output some kind of video format?

I am trying to figure out how to mask local timer interrupts on a specific core of a multicore system from within user space. The interrupts are causing latency spikes of 3-10u that we would like to remove. We are only running 1 thread on the core h everything shielded except for these timer interrupts. This thread makes no system calls and thus is never getting context switched out. I am not looking to turn them off entirely but rather turn them off, run my code, turn them on in a continuous loop. The thread runs in user space which we are hoping to maintain. We also have no desire to modify the kernel if possible. I've read about using spinlock_irqsave() but it appears (not positive) that it must be used within kernel space.

Quote:As the line between securely hosted and controlled enterprise applications and cloud-based applications continues to blur, there's more "legitimate" traffic between corporate networks and the Internet than ever before. This opens up new vectors for attack by hackers nd cybercriminals as more traffic types are allowed through corporate firewalls. The result is an increase in diversity of covert command and control channels, which hide inside legitimate traffic in order to bypass perimeter security. These C&C channels, used by malware ranging from simple spambots to more sophisticated rootkits, vary in the maliciousness of their intent from casual hacking all the way to advanced persistent threats (APT) and industrial espionage.
View 1 Replies View RelatedWhile I was setting up CentOS 5.5 for my first time I faced this problem which is connecting to a printer is not possible, my tutor told me you need to change from eth0 to eht1 or eth2, what does that mean? And if I do this, how can I connect a printer which I have its name and IP address.
View 4 Replies View RelatedI have two NIC Ethernet card (eth1 and eth2) on the same computer (linux) connected by a cross cable.
The two interfaces are on the same subnet :
eth1 : 192.168.200.1 255.255.255.0
eth2 : 192.168.200.2 255.255.255.0
Then i add a route for each interface :
route add -net 192.168.200.0 netmask 255.255.255.0 eth1
route add -net 192.168.200.0 netmask 255.255.255.0 eth2

ping 192.168.200.1 -I eth2 or ping 192.168.200.2 -I eth1
Ping command reaches error : Destination Host Unreachable
Computer A has two network interfaces. One is on a 255.255.255.240(eth0) subnet and has an IP of 192.168.1.6 and the other is on 255.255.255.0(eth1) subnet and has an IP of 192.168.1.64.
eth1 can communicate with modem(192.168.1.254), which also acts as a gateway to the Internet.
eth0 can communicate with my internal LAN, which consists of several computers including Computer B. This subnet 255.255.255.240 has it's own gateway to the internet at 192.168.1.1. However gateways will not apply to this scenario. I just added them to help paint a picture of my network.
What I am trying to do is tunnel http from a web server running on the modem(192.168.1.254) across to Computer B within my internal LAN and be able to view the http content via a browser. Sure I can just open a browser on Computer A, but I'm running Computer A headless. I can also curl it from a command line, but I'd like to learn how to tunnel across a subnet. If I get this to work, would I be able to interact with the site(i.e. make modem configuration changes)? or would it just be one way? How do I tunnel data from the eth1 subnet over to the eth0 subnet and over to Computer B on my internal LAN?
What I tried was the following:
I setup a proxymini to run on Computer A and have it listening on the eth0 interface on port 8080 by using this command 'proxymini -l 192.168.1.6 -p 8080'.
Then on computer B, I setup httptunnel -a 80 -p 192.168.1.254:80 -d 192.168.1.64:8080.
Then I should be able to view the site through a browser on port 80 on the computer I run httptunnel? This setup isn't working.
Two servers, one is RHEL 4, and the other is RHEL 5. They are both on the same subnet, one is 10 the other is 11. I added the Webmin rule to the iptables config file but for some reason, the RHEL 4 server, I can access Webmin but the RHEL 5 server I can not. I checked the iptables file and they are the same for both servers, except two rules which are for other ports.
I'm reading about the iptables and had a problem when I manually added the port 10000 entry after the REJECT entry, but wondering if I need to move it up higher or maybe there's another possible block?

View 1 Replies View RelatedI have a linux desktop with two connections - fast eth0 and slow modem ppp0. Most of traffic (e-mail, DNS, NTP) can be routed simply by IP/mask. But how about http and p2p (torrents, DC++)? Routing by IP is unacceptable, because there is very huge amount of routing rules. I need route http packets (80 port) through ppp0, p2p through eth0 (10000:65535 ports). I've found that splitting traffic by port is possible with marking packets for different gateways. For begin I cleared all tables and bringed up connections.
