I wish to use the VNC server built in to the Ubuntu to easily access it from other computers on my local network. I need to skew the VNC Server port off of the normal 5900 to something else because I am using VNC to access several computers (sometimes simultaneously) so each VNC server needs to be set with a different port #. At this point it is all local subnet connections with no incoming internet access and I am not worried about security.
I installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?
I have Ubuntu Server (x64) installed on my box with Apache2 and Squid. For awahile port 80 (http) was fine, I could update packages and use wget. Then one random day port 80 became blocked for incoming traffic. I couldn't use apt-get and had to change to an ftp mirror to update. Also wget is not working.
I will be setting up a web server at my house. It will be a simple page for my family to keep in touch and maybe some other stuff. Here is the problem: I believe my ISP blocks port 80. So when setting up the firewall and it list the normal port 80 am I able to edit to say 8080? I have a ddns already setup for my router and I am waiting for an email back from DynDNS.com on setting up a new domain to forward to my already setup hostname. I just need to get everything redirected to another port beside 80.
It appears that my ISP is blocking port 80, so I can't set up a proper website on my home computer. I'd like to choose a different port to use (they block 443 also), and I'm not sure how to do this with Fedora (or any Linux flavor for that matter
I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 188.8.131.52/23451 and 184.108.40.206/23452 Receiving on 220.127.116.11/23452 and 18.104.22.168/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [22.214.171.124/23452] take its datagrams from emitter [126.96.36.199/23452] and vice-versa!
My application has to listen to http request and it must be able to read the http header and then forward the request from proxy. All these things must be done on C/C++. please help me. Awaiting for your reply.
* a router/gateway. The external interface have the public IP, an other the DMZ, a third the internal room* a DMZ with the web server* an internal network (internet public room)I redirect the http port 80 to the web server. You should see him there.But I can't see this web site from the internal room. From the public IP /URL I have some sort of non existent message (sorry forgot to copy it). If I call for the private IP, I get the home page (but not the CSS files)the gateway nat's the networks.What is the trick to see the web site from the internal network?
I setting up a web server on my Linux (Centos) using "Apache" web server. And its working well, it will show my websites. But when i try to put my url in a internet browser (ie. only type "myweb.com" ) is only be [URL]. Usually as i know like the other websites (ie. google.com) it will go to auto replace the name be [URL]. But my url here it's not be replacing like that. How to do this configuration. I don't know where the services that i need to look. (ie; named (bind) or in Apache web server it self)?
I'm running Ubuntu 9.10, and am trying to get proftpd to listen on a port other than 22. I've modified the proftpd.conf file, as well as adding the desired port to my /etc/services file, yet if I try anything other than port 22, the connection is refused.
It appears that X Windows under Ubuntu (or Gnome?) is started to listen to a Unix named socket, instead of a TCP port number, for client connections. That's what SSH is forwarding when it does X forwarding. I need to start X applications on a remote machine, and then close the SSH connection. So I need to make the connections directly. This is within a LAN on private IPs, so security is not an issue. I searched on help.ubuntu, but there appears to be no particular document that covers this. Anyone know where this is configured to enable it to listen on a TCP port like the usual 6000?
I just installed KVM on a new system and just found out the hard way that virt-manager cannot be installed on the same machine because of a library conflict, so I will have to manage my VMs from another machine. I will use a SSH tunnel to forward the port, but I don't know what it is. Also, how do I start KVM?
Can't seem to access my squid server on port 80. I have port 80 allowed in the conf for this IP. apache is listening to port 80 but only on the 2nd IP. iptables is allowing through port 80 incoming nmap shows no ports open on 80 though:
Starting Nmap 5.00 ( http://nmap.org ) at 2009-08-20 11:19 BST NSE: Loaded 0 scripts for scanning. Initiating SYN Stealth Scan at 11:19
I'd like to report an issue I've had with Ubuntu server ISO. I downloaded ubuntu-9.10-server-i386.iso by HTTP on ubuntu's website and burned it on a CD. It doesn't work well. I got an error in udevadm sys/devices/pci0000 etc. it was a problem with the hardware, but it seems that it's the ISO that is corrupted. I checked the MD5 checksum and it's not good. Then I download the same ISO a second time (by HTTP) and same problem.
So it seems to me that the ubuntu-9.10-server-i386.iso that we can download by HTTP is not the same as the torrent one. Maybe I'm wrong. Anyway, if I'm right I hope this information will be useful for administrators.
I tried searching and tried different things and have failed miserably. What I am trying to accomplish is have postfix listen on port 587. I have read that I should do this using Linux Firewall rules as to not mess with postfix config. Here's what I have in my ip6tables.
Code: iptables -t nat -A PREROUTING -p tcp --dport 587 -j REDIRECT --to-ports 25 However, when I restart ip6tables I get unknown arg --to-ports
I'm thinking about some ways to limit access to my web-server. It runs Nginx and php in FCGI. The server contains a large amount of information. The data is freely available and no authentication is required but other companies might like to mirror it and use on their own servers.
The requests could be limited on different levels: IP, TCP, HTTP (by nginx) or by the php application. I found some solutions (like Nginx's limit_req_zone directive), but they do not solve the second part of the problem: there's no way to define a whitelist of clients who are allowed to use the data.
I thought about an intellectual firewall that would limit the requests on IP basis, but I'm yet to find such device. Another way was to hack some scripts that would parse the log file every minute and modify the iptables to ban suspicious IPs. It would take days and I doubt this system will survive, say, 1000 requests per second.
Perhaps, some HTTP proxy, like Squid, could do this?
On Fedora 13 is there anywhere else on the system that I have to change to get Apache to Listen to an assigned port, something other than 80. Suppose for instance I wanted Apache to Listen on port 94. I told by the site that their router is forwarding apache to port 94. That doesn't mean I change the Listen in httpd.conf. correct. Apache is still expecting connection on port 80 but in this case 80 then gets forwarded in the router to 94. This is my understanding.
I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:
# This is the ssh client system-wide configuration file. See # ssh_config(5) for more information. This file provides defaults for[code]...
When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.
Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.
I have disabled GDM and start GNOME with gnome-session from .xinitrc . Now when i press Sleep button, GNOME says it cannot suspend. The same is with pressing suspend or hibernate buttons on Shutdown window. At the same time "sudo pm-suspend" and "sudo pm-hibernate" DO work. So, i would like to disable GNOME from listening to ACPI events and to configure everything via acpid scripts. I tried to stop acpid to see if GNOME will not receive events in this case, but it still does. So, the question: how can i stop GNOME from listening to ACPI events?
