Usually we require vnc to take remote sessions. There was one another i think it was called xdrp or xrdp. I am asking this out of curiosity, is there any way to take remote sessions using http. Like in web conferencing, we invite users to join the conference and then we are able to share desktop. Is there any way to do this on one-to-one basis ? is such a technology exists for linux (for any disto) ?
View 1 RepliesWe started hosting some very large content on our site, and the usage patterns in cacti have revealed that the HTTP sessions through our load-balancers drop off dramatically right at midnight.
The logrotate process runs right at midnight, and issues a reload command through the service tool (CentOS 5.5):
Code:
$ cat /etc/logrotate.d/httpd
/data/websites/logs/*_log /var/log/httpd/*log {
missingok
daily
dateext
compress
rotate 7
sharedscripts
postrotate
/sbin/service httpd reload > /dev/null 2>/dev/null || true
endscript
}
Looking at the init script reveals that the reload section is suppose to trigger a HUP of the httpd process:
Code:
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
RETVAL=$?
echo $"not reloading due to configuration syntax error"
failure $"not reloading $httpd due to configuration syntax error"
else
killproc -p ${pidfile} $httpd -HUP
RETVAL=$?
fi
echo
}
In which, Apache should reload it's configuration and start the new logfile without breaking current sessions. However that clearly isn't what is going on. I'm tempted to edit the logrotate script to trigger a HUP directly by cat'ing the PID file directly. Is this normal behavior for Apache when signaled with a HUP?
I'd like to remotely administer my Linux machine at home whilst I'm at work. Only ports 80 and 443 are avaiable, through an HTTP proxy. I don't want to install tunnelling software.What I really need is something that'll run on my server and display a console inside a web browser.
View 3 Replies View RelatedI have a mate who runs the IT in his office. He has recently set up and secured the network but now has an issue logging in to the network from home. Here is the message I got from him regarding the set up and what he is having specific issues with.
I was really pleased with the results on my Pen Test; the office itself is a pure MS environment but the testers all use Ubuntu 9.10 to hack with. The main tools of choice are Nessus and Ophcrack with a bit of NMap. It's pretty scary what you can do with just these tools. I had a Wireshark trace running all the time and it's fascinating to watch how these guys crack open a system. The only really major change I've had to implement on my network is to force the use of SSL as a transport layer for our remote desktop sessions. This has forced me to start using MS RDP Client 5.2 because it can use certificates on the session. The problem I've got now is that the Terminal Client in Ubuntu can't do this so I can't remote in from home on my Ubuntu laptop.
I have a need to support multiple remote desktop sessions. Each one seperate from the other and run concurrently.
Windows XP supports one. Widows server support two. How many will Ubuntu server suuport? How about Ubuntu desktop?
I currently have a RHEL 5.4 software development server. A lot of my developers are using windows desktops and they need to run interactive sessions on the server. I need to support between 4-6 concurrent users on the server. I tried doing this with VNC but I was never able to set that up for more than one user at a time.
View 2 Replies View RelatedI have a Debian VPS running Lenny and I'm trying to setup a way to run remote desktop sessions from it. I went with FreeNX, NX client for windows from nomachine, XDM and xfce4. All seems to have installed well, but I can't start an NX session on my box. I can connect to the server and authenticate, but the client hangs on "Downloading the session information," eventually timing out. The log output is below - I'm not even seeing an error message. Any ideas?

The only thing I noticed during install, which was about 400 packages since this was a barebones VPS, was that I should consider recompiling the kernel with CONFIG_SOFTWARE_SUSPEND=y. I don't know if this has any impact on session information, however, since this is a new session, not one I'm trying to resume.

View 1 Replies View RelatedI need to redirect all http/https/ftp traffic through the remote proxy, but when I changes connection settings in browser or in System->Preferences->Network Proxy it doesn't work well: instead of getting page content browser asks for saving some short (8 bytes) file with the same content for all requested pages. It happens in Chrome/Opera/Firefox. This proxy requires authorization and works on computer with Windos XP. It worked well when I was using Windows 7 and Proxifier, now I have Ubuntu 9.10 with all available updates.

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

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.

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?

BUT, when I want to shutdown my laptop, I am in trouble since the remote processes are killed.
I did my research and found out that "screen" is a great solution for me, it is! (As long as I don't SHUTDOWN my laptop). Isn't there a way to "persist" the "screen" sessions so I can shut it down and then re-attach to a session?

View 3 Replies View RelatedI am no longer working on the Linux-machine directly, but I'm using Windows puTTY to get a terminal-session. Within that puTTY window I want to switch (or maybe create first) several sessions between which I can switch arbitrarily. I have read about using Ctrl-Alt-Fn, which doesn't work, most likely due to the puTTY interface. I have tried chvt n, which doesn't do anything either (or that it seems). I have tried "bash &" and got bash in the background, which I could call forth using fg, but then had to stay with that and couldn't switch anywhere. Only option was "exit". So, what's the correct way to get several sessions in that puTTY window and switch between them?
View 2 Replies View RelatedIf I ssh to a remote machine and then lose internet connectivity, the session freezes. I can't control-c or otherwise abort and go back to my local xterm or terminal prompt but if I wait several minutes it will do so.
There must be some way to force it to abort the remote ssh session when connectivity is lost. I'm on a Mac but I believe this happens on cygwin or linux as well.
Firstly, what's the best way to execute commands on startup, cron? Can I use su in a shell script to switch between different users, if so how?
How do I create several detached screen sessions on startup? screen -A -m -d -S test ./script.sh seems like it should work but using it in a script started by cron doesn't show any screen sessions running after booting.
It looks like the screen session is closed after the command finishes executing, can I keep it open so I can see the output?

I'm trying to understand if anyone is left on a server. Basically I manage a simple linux server remotely used by 3-4 individuals. I can never tell if someone is actually on or not using w/who.What I'm seeing is some people having what appears to be inactive/lost VNC sessions. I don't understand idle fully, but I do believe a program (without user interaction) can clear idle back to 0, correct?Anyway, I'm asking because every now and then I need to reboot the server, and I do not want to interrupt any program working on calculations or waiting on having the data saved.

I just added 8 additional vncserver sessions(Xvnc) (using a well-documented procedure my predecessor used) to my RH Enterprise 2.4.21-4 (OK it went by fast) server. This brings the number of session listed in my /etc/sysconfig/vncservers file to ~32. Applications and terminals now seem to choose if they will open or not in the Xvnc session and not all sessions start at boot. I can start them manually, and they will work, but then they stop working properly. You can open a session, view the active desktop, click on menus and associated drop-down items to try and open apps, but the apps/terminals just won't open. Is there a limit to the number Xvnc Sessions that can be managed? If so, what is it? This happens whether I try to connect from a Winddows box or another Linux box.

I was doing some rather lengthy procedures using a terminal. Then I wrote script using Kate, and input it into that terminal, and then realized that I was logged in as a normal user in that terminal as opposed to a superuser, which is how I was logged in at the other terminal. I've never noticed this before because I've never done anything that takes this long.
Is there any way to link all terminal sessions in such a way that they all show me logged in as the same user? I don't even know if this is even important, but I don't want to risk losing any things that I had done.
