There are 2 IPs assigned to a LINUX machine. Now I installed a Tomcat instance on it. After I started the Tomcat I can access via both IP as follow:
http://ip1:8080
http://ip2:8080
But I just want the Tomcat binded to IP1. How can I do that?
I am having a problem.I use Ubuntu 10.04 server edition.Two computers on LAN one with Public Ip A other with local (Class C IP)say it BWith a third computer in same subnet I can access a TomCat application running on B as http://Ip of B:8080/applicationI want to use A as a Reverse Proxy for this application to be reachable from internet.So on Googling I came across some thing known as mod_ajp I enabled that on my Server A asa2enmod proxya2enmod proxy_ajpa2enmod headersbut after that I am not able to understand as how do I define vhost to be able to forward HTTP request which come on A as www.myserver.com/appto B which I can see internally as http://Ip of B:8080/application so Tomcat on B handles this.
View 4 Replies View RelatedI've got my first EC2/cloud instance of Ubuntu up and running. This is my first time really dealing with the server edition. I've loaded Apache, Tomcat, PostgreSQL, and Webmin. I've got a public IP on the instance and it is working. I've opened, for now, ports 80, 8080, 443, and 10000 to 0.0.0.0/0.
I cannot get into Tomcat Manager or Webmin at all through a browser. For Tomcat, I've restarted, stop/started, and verified that Tomcat is running. I installed Webmin all through apt-get commands so any dependencies should have been installed (first time doing it this way), but cannot get to the login screen. But if I just go to the IP, Apache goes to the "It Works." splash page. Did I miss some set up? Is there an internal firewall in Ubuntu Server edition that needs to be set?
I have KDE 4.4 and Firefox 3.6. Whenever I click a link from a plasmoid widget, it tries to open Konqueror and another instance of Firefox. The page actually loads in the opened Firefox window, but the task bar shows an instance of Konqueror and another instance of Firefox, that keeps loading for a while then close. See image below:
I currently have setup the browser default application as "firefox". If I set this option to use the default application, it opens in Konqueror and I don't see additional windows in the task bar. If I change the option to "firefox %u", then it exhibit the same issue, but the process is much faster, so the loading windows don't stay for long in the task bar. Additionally, it opens the link on a new Firefox window and opens the page twice. Although Konqueror is not loaded, the bouncing icon next to the mouse pointer shows up and stay for a while.

I might just be crazy or particularly dumb today but what I'm trying to do is have sed replace the first and second instance of a character on a line but not after that.
Basically it is a csv file with a date formatted as dd/mm/yyyy and I need to completely remove the slashes. No problem using:
Code:
sed 's////g' < file > outputfile
The only problem is that one of the columns after this may also contain these slashes and shouldn't be removed.
I must have read every single sed page on the net today to find a way to do it to no avail! Is it as simple as :
Code:
sed 's////1' < file > outputfile
And then run the same on the output file again? these two slashes will always be the first and second slashes in the file.
I'm trying to use tigthvnc (with ssh tunneling) in order to acess remotely my parent's kubuntu desktop. That way I'll give them some support when I'm at my home or office.
Practically I hadn't used vnc with linux, but I recall having used with windows. In linux when I logged to the remote machine (which runs vncserver) it's opens a new instance of X server. I'd like to access to the X session that's already opened. Let's suppouse my parents are logged into X with the user: john. I'd like to access john's session, to see and check his applications. In one word I'd like to vnc in linux behaves the same way as windows.
Is that possible with vnc? I'm using tightvnc. I tried -shared option in client, but no success.
how to stop the instance before shutting down. I tried dbstop and oracle stop, but neither work.

So i'm really loving the whole gnome-do/docky thing. My question is that on other docks, you can hold down a modifier key to launch a new instance rather then switching to an already opened instance of an app. So lets say I have chrome on the win7 dock
first click launches chrome
other clicks will focus the opened window
shift click will open a new instance of chrome
ctrl-shift-click will launch a new instance as admin
Is there anything similar in docky?

I've beeb setting up keepalived/haproxy as a load balancer for our site.
If you keep it down to two load balancing instances it works just fine. However, I was told to add a 3rd load balancer to the mix and that adds a new wrinkle. I need to add a new keepalived instance and I can't quite figure out how that's done.
It would seem to me to be an issue of the priorities as that is the only thing I altered in the files. Initially, nodes A and B were set to 101 and 100 respectively. I set node A to 102, node B to 101 and node C to 100... keepalived restarts and the virtual IP is pingable. But the website goes down!
SO then I tried Node A set to 101, node B to 100 and node C to 99. Same thing, I restated keepalived and the site goes down, tho the virtual IP remains pinagble and keepalived and haproxy are running.
here is a sample config file from my setup:
Code:
vrrp_instance VI_1 {
state MASTER
interface eth0

is it possible to run for instance pan remotely via ssh and make that instance of pan running on server, regardless upon closing it via ssh?for example i would love to do: start pan instance via ssh on the server keep it open while downloading close the ssh session, keep the pan running on the server in background. open ssh session and access the same instance of pan running on the server etc something in that loop.im unable to do that because when i close pan ssh remotely the instance automatically terminates on the server.

View 1 Replies View RelatedWhen a new instance of a running KDE 4 application (kwrite, konqueror, etc.) is run under opensuse 11.4 with KDE4 it seems that the default behaviour is to open a new tab in the running instance.
This occurs when the new instance is called from the command line; the start menu; the run dialogue; or a desktop icon, even when called from a separate desktop. In konqueror the menu option <File> <new window> opens a new tab and seems redundant.
How can a user force KDE 4 applications to run a new instance in a separate frame / window when another instance of that application is already running?
