where to look for setting up my web server A so that if I have to bring it down for maintenance, all web traffic will go to my backup server B. I thought about changing DNS entry but that will take time to update.
View 2 RepliesI've two internet based server ( xx.xx.xx.xx and yy.yy.yy.yy ) The Y server is running VNC server and is responsible for answering to VNC sessions. But I need to hide the IP of Y server so I want X server to be as VNC Proxy and redirect all VNC sessions to Y server.
I guess the best way is to use iptables but actually I can't get it working so
I'm trying to workaround a limitation in a server application. The limitation is that I can only connect to a LOCAL mysql database. I am trying to fool the server in to using a remote mysql database. I was hoping to do this by simply forwarding 3306 to another server on the same subnet.To that end I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.
View 14 Replies View RelatedI'd love a hint or two on the following problem. I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.
Code:
iptables -t nat -A PREROUTING -p tcp --dport 3306 -j DNAT --to 128.XXX.XXX.XXX:3197
iptables -A FORWARD -p tcp -d 128.XXX.XXX.XXX --dport 3197 -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE
Since locally-generated packets will never hit the PREROUTING rule, you'll need to setup a near identical rule using OUTPUT to make it work. Here is what I've tried:

View 1 Replies View RelatedI have a scenario where a Debian (in this case) device will be connected to an existing LAN.What I then want said box to do, is to query the LAN to see if there is an existing DHCP server present. If there isn't one - then simply use the Debian box as the DHCP server (which works fine atm).If there is an existing one - I need the Debian box to be able to turn off it's own internal one and get it's details from the existing server (ie. change from server to client).
These action will need to be sat in the background as well - just in case another DHCP server appears on the LAN after this box does. Don't shoot me for saying it - but I know Windoze server does this. Is there a 'script/util' that anyone knows of (I am trying to do this auto-magically)?
I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.
Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.
In trying to upgrade from the default VNC server, I have installed RealVNC on latest Ubuntu Natty Narwhal, and it seems to work fine. But I would like to make it so RealVNC starts in the background when ubuntu is booting. I found the website below, but those procedures seem a little dated, so I thought I would check here first. Does anyone know of a good way to load the vnc.so module on boot? I have nvidia drivers and such installed, so I am afraid adding the load module section in xorg.conf might make it somodules that I don't know about don't load
View 1 Replies View RelatedI have been beating my head for the last few weeks on this problem, (although I have been taking the wrong approach, it seems).
I need a gateway to direct web traffic to three separate servers/domains. I have been trying to do this with both a dns server and , (seperatly), apache server to forward requests. The dns server was a no go, and <i can only get apache to redirect http and ftp.
After Googling this ALOT, I believe that what I need is a gateway server to redirect my traffic to the 3 different servers. I have been reading about using using nat and iptables for this and was wondering if anyone had any advice/suggestions on this. The other thought I had was to use something like pfSense to create the gateway, but I am still reading the documentation, and I am unsure if this approach will work.
The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.
My current setup is:
old server:
www.mydomain.com main site
www.mydomain.com/subdirectories related sites from same server, different directories
I am adding an additional server that I would like to initially only use for the main site, something like this:
new server
www.mydomain.com main site
www.mydomain.com/subdirectories would be pointed back to the old server instead
What's the best way to redirect the traffic for the sites found in sub-directories on the old server?
I'm using Apache 2 on a Linux server and I was wondering if it was possible to redirect certain IP ranges to another page. I know it's possible to block an IP, but is there a way to block all IP's and only allow a certain IP range to connect, such as 5.87.xxx.xxx? I own this server, so if I need to use another OS, webserver, change configuration files, etc., that's fine.

I know that I can use the Redirect directive in apache to redirect users to another domain with "Redirect permanent / http://www.newdomain.tld", but when I use that line the entire URL is preserved.
For example, if a user tries to access [url] they will be redirected to [url]. Is it possible to redirect all requests to the root of the new domain [url]?

The problem is i have many other contexts.
context1

context3
So if you go to [url] you get re-directed to context1. Which is not what I want. Basically I am asking how can I set the default context on the server to context1 if you do not type it?

I'm hosting my own dedicated server with Ubuntu Server 10.10. I have it set up with a static local IP, and I've configured DynDNS to link up with my router and allow my server to go live to the internet. I have all the appropriate ports unlocked, with the exception of port 80. This port is blocked by my ISP (Charter) and I can't use it. Due to this, I configured my router to listen on port 81, and direct it to my server.
So, In order to view it, you need to go to the IP XXX.xxx.XXX.xxx:81 Today, I registered (www.online-self.com) in hopes of getting around my current mask (provided by DynDNS.com (omegame.selfip.com). So here is my dilemma, When I go to the host of my domain name , I want to redirect my DNS to my server IP.
I can't seem to do it though? They want a strict IP address, no port extensions. How do I get around this so that my domain name and IP address link up? I'm thinking I may be missing a step, or maybe I needed to register a domain name that simply redirects? I'm starting to get confused on what I should do next. Can I even do this?

View 1 Replies View RelatedI have several web servers running apache on my LAN. Each internal server hosts a number of domains.I would like to make these available to the internet and make sure they all get to use port 80 and 443.My idea was to put Apache on the firewall and have all http(s) traffic from the Internet to my firewall be redirected by Apache to the different internal apache servers. This, in theory, would allow me to keep the standard http(s) port.
Can this be done? I was thinking of mod_rewrite and mod_redirect but in all honesty, I'm a little at a loss on where to start.Can someone point me to relevant documentation or give me the basic idea on how to start?
