I have a USB powered LED light attached to my pc. ( I keep my cave dark and this little light perfectly lights up my desktop and keyboard) I would like to be able to turn off the USB port the LED light is attached to when the PC goes to idle and dims my monitors and when the PC goes back to active I would like the LED light to come back on.

View 2 Replies View RelatedWhen I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.
The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.
What is causing this?

View 1 Replies View RelatedI'm running Fedora 15, and am trying to run a program that uses gsoap/soapcpp2 2.7.17 to communicate with different parts of the program. As far as I know everything has compiled correctly and I am using the same versions of the required libraries as several working installations. However, every single time the program tries to open a port, the program is unable to do so. This happens no matter what port I specify.
if there is anything in fedora that would limit or disable the ability of the program to open a port to start communicating. I have tried disabling the firewall with no change to the behaviour.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?

I have a mail server i need it to send message via port 587 not port 25, i make some changes to my postfix server which i use and it is already successed making a telnet to 587 port like it :
[Code]....
I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?
The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.
The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.
I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?
When I use the following command:
ssh user@ssh_server -L 5500:localhost:5500 -p 22
everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:
ssh user@ssh_server -R 5500:localhost:5500 -p 22
I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...
I want to set my ip as static and port forward it through a specific port can anyone help me with this im using ubuntu 10 with 64 bit OS
View 1 Replies View RelatedIs it possible to have the machine suspend when idle at the gdm login screen? I understand it is possible when a user is logged in through the System > Preferences > Power Management controls. What is happening is that the computer is sitting at the login screen and stays on, wasting power. I'd like it to suspend/sleep after a timeout.

View 2 Replies View RelatedVERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.
I tried to make "ssh tunneling", but failed and got this message.

Is there any way to verify if packets being trafficked over a certain port are valid for the service you want to use this port for?
One obvious example that probably clarifies my question:
When I open port 443 (outgoing or incoming) for https/ssl traffic, I don't want this port to be used for say openvpn traffic.
Thus: when someone wants to surf to a website with https, it should be ok but if someone wants to connect to his home openvpn server over that same port, it should be blocked.
I'm trying to use iptables in order to forward all the incoming packets for port 5555 to port 5556 on the same server (192.168.2.101).
I wrote the following commands:
iptables -A PREROUTING -t nat -i any -p tcp --dport 5555 -j DNAT --to 192.168.2.101:5556
iptables -A FORWARD -p tcp -m state --state NEW -d 192.168.2.101 --dport 5556 -j ACCEPT
I've had this bug on pretty much all Linux distro's I've tried in the last few months, but because I love Ubuntu and I can't seem to find this bug reproduced anywhere (though I'm not sure it's a bug worth reporting if it's just me) I decided to bring it here: Whenever a program that is not resource intensive (for example, Update Manager while it's downloading packages) is running for around 20 seconds, and I am not typing or moving my mouse, the system will hang. It will sit there for hours on end unless I move the mouse or hit a key.
Worse yet, it will hang on boot and shutdown too. I often have to hit a key to get the hard drive to start reading again and for anything else to happen for that matter. I'm using Ubuntu 9.10 on a relatively new laptop, but like I said before, it's happened on a bunch of distros: Debian, openSUSE, Fedora... I just have no idea what could be causing it at this point.
When I'm on windows 7 my core i3 processors automatically clocks down when not much CPU power is needed. Somehow I have the idea that ubuntu 10.04 doesn't auto clock down my CPU when idle. I can tell by the short life my full battery has on ubuntu. Only 2hours compared to 5 on windows 7. Is there a way to manage this? So that the CPU automaticly adjusts it's clock settings?
