Fedora Networking :: Can't Connect VNC Using Http
Aug 6, 2009
I have Fedora 11 and have successfully set up VNC so that I can connect within the network (direct using vnc client/server setup). I am in the middle of working on a problem and have a fried who is in another city and was trying to set up VNC so that he could connect via http, which I know is possible (that it listens on range 5800 + the display number - mine is 3 in this instance). For the life of me I cannot get the java http viewer to work, here is what I have done so far: My vncservers file:
[Code]...
My router is set up to forward incoming requests on the range 5900-5910 and 5800-5800 to this computer. I have opened ports 5902, 5903, 5802, and 5803 on my linux firewall. So far as I know, this is all that is necessary..well. Whenever I attempt to connect via [URL]:5803 I get a time out error. What could be wrong?

I have an Ubuntu 10.10 machine hosting a virtual Windows machine on virtualbox. I have 3 servers I connect to using SSH with password authentication, on standard port (22)For some unknown reason, I have one server that I cannot connect to Via SSH using putty/terminal or HTTP via Browser from my Host nix box, but my Virtual machine CAN connect via both. Same machine, same network, one virtual with a bridged adapter, one physical network card connected to my network.

How do Http requests and responses go from a client to the server? IS a TCP Connect Tunnel always formed or is there some different mode ?

I'm using the Netopia 2247 router. I'm on Fedora 13, on a Thinkpad T60.
For some reason, ever since I switched my ISP (just last night), I can't connect to any non-HTTP services. I've tried Thunderbird for IMAP, FileZilla for FTP/SFTP, and Empathy for XMPP. Nothing connects. Chromium, Firefox for HTTP: works just fine. I know it seems really far stretched to think that this could be an issue on my end, but: I've checked with the ISP, and they insist that there's no reason this should be happening. They will be coming in tomorrow to take a look at wiring and all that though. I'm able to access my IMAP email via my smartphone's built-in mail client, via my new ISP. This is using a Nokia N82, with default messaging client (just called Messaging). But, who knows, maybe N82's email client actually uses HTTP? (Unfortunately, my only "desktop" computer is T60, and I only have Fedora installed on it; I realize the icon at top right shows Windows, but that's my work desktop, and I definitely can't take that home for testing). I've checked the firewall settings on the router, and put them at the very lowest setting.
Again, I know it seems far fetched that there's something wrong with my system (e.g., I've traveled with my laptop and have never had any problem accessing IMAP or FTP on other connections), but I just want to make sure I've exhausted every possibility. So, if you could entertain the possibility that it's something on my end, what might it be?
Maybe disabling SELinux might help? I'm going to try that when I get back home. Although: I feel like an SELinux dialog would've popped up if that was the problem.

I'm trying to set up a server for an NPO who connects to the Internet through an internal proxy (Websense). I can't access the Internet unless through the proxy.
Since it's a server I did not install a GUI so I'm wondering how to connect the new server to said proxy server. I have the IP address, port number and username-password for the proxy server. The new server has a static IP address and is ready too go!

Using netcat, nc(1), craft a valid http/1.1 request for getting http headers (not the html file itself!) for the main index page of www dot aalto dot fi. What request method did you use? Which headers did you need to send to the server? What was the status code for the request? Which headers did the server return? Explain the purpose of each header.
nc -v www dot aalto dot fi 8080
HEAD / HTML/1.1
host: www dot aalto dot fi
And it returns:
200 OK
Content-Length: 858
Content-Type: text/html

I really don't know what does it mean. Question 2: Using netcat, nc(1), start a bogus web server listening on the loopback interface port 8080. Verify with netstat(, that the server really is listening where it should be. Direct your browser to the bogus server and capture the User-Agent: header "Direct your browser to the bogus server and capture the User-Agent: header" I don't understand this question.

I can ping certain websites, such as Adobe.com, but I cannot access them via http (i.e. through firefox or yum). Some websites work through http, like Google, while others don't. The ones that don't are always the same.
What really hurts here is I cannot yum to all repos i'd like to. Since the same sites cannot be accessed through firefox, I imagine there is some underlying problem with my system's HTTP setup.
My windows machine on the same network works fine. I have had this problem since I installed Fedora 10 about 4 months ago. I'd rather not reinstall as nothing really seems broken (aside from this http issue), my system is completely up to date.
If I use a public proxy website I can get to the sites I can't connect to directly. I've followed a FAQ from mozilla for Firefox that hasn't helped, but I don't think its a Firefox issue since yum suffers as well. I also followed the fedora FAQ and I have been using OpenDNS servers.

I have come across a fairly minor issue however. When using any IM clients I am unable to login to MSN using the direct connection method. Instead I find myself having to connect using the HTTP method. I wouldn't worry about this except many of my contacts are complaining that they are getting "message unabled to be delivered" errors regularly when trying to contact me.

My box has to connect to internet using specified http proxy.I have set proxy in both kde control center and yast2 control center. They both tell me the proxy works fine. But when I really try to use yast2 to update my system, it report an error:
Code:
Failed to download ./repo/repoindex.xml from [URL]
History: - [AbstractCommand.cc:195] URI = [URL]
Even I try
Code:
export http_proxy=http://XXXX
yast in command line,the error still exist.
In debian apt-get and slackware slackpkg,my proxy works fine. So I am sure it is not my fault and maybe it is a bug of yast2.

I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something.
Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.

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 installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

My school network uses a http proxy to access the internet, but I am dubious about the security, and so I would like to use http inside ssh to keep my data secure. I don't really know where to start on this, so a step-by-step guide, or links to resources, would be helpful.

I have a http proxy account. It works well under windows through wodTunnel(an active X control component). But, I usually works under linux. I want to use it here. But I don't know how. I tried gstm, it can connect to the server successfully, but it seems can't respond to my http request. What should I do next?

Machine 1) I have a Server with RHEL5.
eth0 = 192.168.48.x (static class C ip connected to VLAN switch)
Internet available via HTTP proxy through vlan but from other main server but not from machine below.
Machine 2) I also have a Server with RHEL4.
eth0 = 124.30.XXX.xxx (public IP for availing internet)
eth1 = 192.168.60.xxx (class c ip to share internet via squid on the same LAB)
eth2 = 192.168.16.xxx (class c ip connected to VLAN switch)
Now what I want is ssh connectivity available to Machine 1, so as to enable remote machines on the internet connected. I know that it might be hard for Machine 1 to share ssh directly on the internet but if there is any kind of tool or tricks to setup pls tell. So the only chance is ssh via machine 2 then after connected to Machine 2 then again ssh to Machine 1. But how do I make ssh available online? IPtables are set correctly machine 2 can't be ping on the internet.

I just upgrade my Fedora 14 to Fedora 15 RC1.I found the critical issue for me that Juniper Network connect(SSL VPN) didn't work for me again.I wonder if the network interface name changed impact this, but I am not sure about it as I didn't see any obviously error.I can connect the VPN auth page with my username and password after I switch my Java plugin to Sun JRE( I use google Chrome).As the Java VPN applet started, it appeared for a while and shutdown again. I think the VPN auth has been passed at that time, the problem might about creating the VPN Tunnel.

eBox has two virtual nics (above) - one is NAT (eth1) and the other is bridged (eth0)
The client is on vmware ESXi 4.0. It's an openSUSE 11.2.

I have a server (Fedora 12) setup at a client's datacenter and the network is setup to allow me ssh access into the server, but prevents me from opening any connections from the server. However, I need to make http and https request from the server. What I'd like to do is forward all http/https traffic through another machine outside the network.
I've been looking at the documentation for ssh and the various options there and have gotten so far as to enable initiating an ssh connection from the client network back to my machine, but am not sure where to take it from there.
Here are some of the commands I've used so far:
Code:
I'm attempting to bind port 80 to be forwarded through the local machine. I assume I use "ssh -R" to create a dynamic tunnel to forward requests but I must be missing something.
By the way, root login via ssh is disabled.

My Server Name comes up empty and I want to change the default Webmaster email address root@localhost to something else, but I can't change anything. I enter mu new server name and e-mail address, but when I click on the OK button I get a popup box which asks me if I want to save and exit. I click on the Yes button, and the box disappears. HTTP Server configuration does not exit and my changes are not saved.
