i am using centos 5.4 (5.5?) gnome on multiple machines in a local network.is there a program available that does the following:you type a message in a 'note'screen on one computer and can send it to one (to choose) or all machines in the local network that are online, so you can read the message on these other machines screens.
View 6 RepliesMy two machines are both running Ubuntu 10.10. I want to transfer program files between them using a local area network.
My Ubuntu machines can both see the Window machines on the network, and get files from them. But my Ubuntu machines do not detect each other as being on the network. Nor can my Windows machines detect my Ubuntu machines.
From what I can tell, that's normal, and I've become resigned to using a pendrive to transfer files between the two machines. Or even sending files as email attachments.
there is a clean and easy way to transfer files between two Ubuntu machines on the same local area network.
In the firewall, I opened port 5900 for TCP traffic. Now the console is displaying packet information whenever a connection is made. Why does it send a message to stdout/stderr for an allowed connection? How can I stop it? Logging level is set to critical only, and not-accepted packets should only be logged for the internal and DMZ zones.

I am new to networking and trying to setup my own local area network using virtual box machines. I have installed BIND 9.7.3 using yum in Fedora (dns server) and created all necessary .conf and zone fil es. I am successfully able to resolve domain names on this host machine (dns server). for example dig @dns.domain.lan client1.domain.lan correctly resolves domain name.

I have a postfix mail server on ubuntu 10.04 lts behind a router. so all local users are fetching/sending mails through ms outlook using local IP. Sometimes when internet goes down and any mail send then it bounced back immediately saying domain not found. Can u please tell me how i configure to hold all mails in postfix server rather than bounce when internet fails and will pass through when restored the internet around 15-30 minutes?
View 2 Replies View RelatedI've run into a problem gathering usage for my xen virtual systems. With my old model I used to gather all network usage via my cisco devices using the the counters for each port. Each system had it's own port on the switch, and I tracked network usage accordingly. Now that I'm using xen for virtual systems, and multiple vm's share the same switch port, i'm not exactly sure what my best option is for tracking usage.
I thought I may be able to setup vlans on the switch, and bind each vm to a different vlan using vconfig... but it seems like there has to be a better solution than that.

I'm using CentOS 5.5 as a media server to stream media content over my local network. Currently i'm having problem while installing last.fm scrobbler.

I'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 RelatedWe are in the process for Integration Network with our Government Network.
Let say that our network are 192.168.0.0/24
And the Government network are 10.0.0.0/8
I want to know if the local network can resolve the internet names in Government Network. I am using Bind for DNS.
I'm running a "relatively standard" home network environment. That is, I've got a DSL connection to my ISP, and am running a router/NAT environment that connects a number of machines -- Mac, Windows, and Linux -- to the external network. Internally, all the machines have addresses in the range of 192.168.0.x. However, because of the static/NAT address mapping, the machines whose internal addresses are mapped to external static addresses show up at external hosts as 216.xxx.yyy.zzz (the address range assigned to me by my ISP).
The other machines, which are on the network via NAT, show up as 66.xxx.yyy.zzz, the address assigned by my ISP. Finally, I'm running a local DNS server that handles addressing issues for my domains and sub-domains that are hosted on local machines. All the machines use this local server for their DNS, with my ISP's DNS server as secondary. All of this is to say that it's more or less a pretty typical configuration, and, in general, everything is working fine.
Here's where it gets tricky:
* Machine A is a Fedora 10 linux box, which hosts an externally visible domain and runs, among other things, a web server. It's assigned to one of the addresses that's mapped to a static IP address.
* Machine B is a MacBook Pro, running Snow Leopard (10.6). It typically runs at 192.168.0.6, which is NOT one of the addresses mapped to a static address, but "just" a NAT address.
Now, suppose Machine B hits the web browser run by Machine A: the log files should show the traffic arriving from the local address, 192.168.0.6. However, it instead shows up as coming from 66.xxx.yyy.zzz, the external NAT-affiliated address. This seems wrong, especially since all the other machines on my network show 192.168-type addresses when hitting the web server.
I now change Machine B's address to 192.168.0.5 -- one of the statically-mapped addresses. Browsing traffic is now arriving from 192.168.0.5, which is (I think) as it should be. I now change Machine B's address back to 192.168.0.6. The web traffic on Machine B is now reported to be arriving from 192.168.0.6 -- NOT 66.xxx.yyy.zzz. It's complicated by the fact that I don't know where to look for the problem. All the log files on all the machines seem relatively normal; there are least no glaring problems screaming out from them.
i have a small issue, to make our network more secure, i now require outgoing email to require authentication. Now the problem..i have a automated mailer that does not have the option to authenticate. is there a way to allow a certain email address or the local network to send out without authentication? If i cannot do this for a single email user to allow them through with authentication, how would i remove the authentication paramaters in the postfix smtp..
View 2 Replies View RelatedI want to build a topology of this kind:
|eth0 (a.a.a.a) |
Linux PC |<----------------> | ROUTER
|eth1 (b.b.b.b) |
|<----------------->|
the linux machine has two interfaces eth0 (a.a.a.a) and eth1 (b.b.b.b) connnected to two interfaces of a router. Now that if I send any packet destined to b.b.b.b from a.a.a.a interface on the linux machine, it should take the folowing path: eth0->router->eth1 . and it should be the same for vice versa.
I was setting up a new Linux box and router today and when I was looking to see if my custom DNS servers were being handed off in DHCP to my Ubuntu box I realized that the isp was shoving down onto my machines their dns suffix. Since I have configured my dhcp scope in the router to hand out a local dns suffix I am not sure why my suffix is not being used. Is there a way to use the .local dns suffix for both my linux and windows machines with dhcp instead of having to manually set the suffix?

Yet, when I access the www.homepage from elsewhere, my www.homepage is accessible.
I can browse to my www.homepage by entering the local IP address into browsers on both local machines, so I know the machines are talking to each other. Just not letting me get in via normal internet browsing channels.

I've been trying to understand how Linux creates the network/interfaces on a machine (been reading the Linux admin guide), but as I'm pretty new to this subject, I've got lost in the forest.
To provide with my goal:
1.) Learn about network setups on Linux
2.) Be able to maintain my own (virtual) network
3.) Configure my (virtual) network
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)

I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
