I'm writting an app for desktop and embedded linux and I need to get information about the multiserial port, and I need to know which port is been used (by a printer, por example).The multiserial I'm using is an Altera Corporation Device 0004, and I just need to tell how many ports are there and how many is been used.

View 1 Replies View RelatedJust did a check on "shields up" and it says that ten of my ports are open. I get the same result with or without both shorewall and firestarter. I suspect it may have something to do with the mysql server packages added automatically during installation. Am I right. If so, what can be done about it? If not, has anyone any idea how to keep my ports closed?

Only reason I can think of as to why I can't connect to it is because my ports aren't open. I also recall SELinux complaining about something awhile ago, I can't seem to bring that up any more for some reason.

View 9 Replies View RelatedI'm starting to feel like a spamer or something. (I don't usually have this many computer questions, I'm a nerd, but known NOTHING about ubuntu).
All of a sudden NONE of my usb ports work? I can't get USB drives to work or an external drive. They aren't recogonized at all and the lights on them don't light up.
All i need is to see a list, window or anything that shows all of the serial (rs232) com ports that are on my Ubuntu 10.04 machine and what their associated port numbers are.
I have one com port that is on the motherboard (so obviously its com 1) and it works fine. but i also have a usb to serial (FTDI) com port that i cant figure out what the port number is...
If i've accidentally deleted the vboxusers group off my list in System-> Administration, is there a way to get it back? I really need to unlock my USB ports for my VM.
View 3 Replies View RelatedI want to test automatically if the USB ports are in use.
I want to test it in a bash script
I found some information about ttyUSB0 in the /dev/
The problem is, there is usb hub between the system and the mouse/keyboard. The other USB port is in use for the Ubuntu live usb.
When I open the /dev/ map virtual and pull out the usb keyboard the hidraw1 diappears, same for the keyboard.
When both are out and I pull out the usb hub, nothing happens.
Do anyone know how to test it?
I need to talk to several serial ports. I was thinking of having a bunch of USB to serial cables and then plugging all of them into a USB hub, which goes to the computer. What I want to know is, will I see each serial port as a separate thing? With 1 USB to serial cable and no hub, I see /dev/ttyUSB0. With this hub, will I see /dev/ttyUSB0, /dev/ttyUSB1, etc?
View 1 Replies View RelatedI've installed Debian Lenny on a Fujitsu Amilo L7310GW, and everything works well, except for the usb ports. Anything plugged into them doesn't register at all. If I plug in my usb pendrive with the light then the light comes on for a moment and then nothing.
I started up Knoppix 6.2 from the same pendrive, and it starts to boot, right up to where you can choose the OS and options, and then a bit further but then it fails because I suppose enough of the OS has been bootstrapped to use it's own usb facilities.
I've looked at the logs, dmesg/syslog/messages/debug, and also got some output from lsusb but I can't see what could be the problem.
I can successfully forward a port via:
PHP Code: ssh -L 5900:localhost:5900 test@192.168.5.1
how do I forward several ports at once. This is a wrong example but:

View 1 Replies View RelatedHave configured squid in routing server and it works fine. Able to block sites and allowed all http request to pass through squid so able to monitor http traffic. And the downloads from linux machine like wget, ftp, etc.. and from windows download manager cannot be monitored which is drawback right now. In squid is it possible to allow ports like ssh, ftp etc so that it can also be monitored? If so need some spark ideas on it.

View 1 Replies View RelatedI'm using slackware 12.1 for some time now and this morning (kind of the first day of my winter break) I decided to fix an old USB pen drive to save some docs... (bad idea #1). I had some trouble deleting some files. Slack kept telling me that the files weren't there, so (probably not the smartest decision ever) I decided to "format" the tiny thing. (bad idea #2). Cfdisk wouldn't do it and I ended up on fdisk. (bad idea #3). I thought I was formatting 4 partitions in the same pen drive which now I think might have been my four usb ports. After that, no USB Ports are working at my computer at all. I even boot slackware 13.1 from a dvd and still couldn't get any USB working. Rc.hotplug is nowhere to be found.
At the end of dmesg, I get:

This individual has been within the Ohio State computer labs for sometime because educational endeavors ceased building another Linux personal computer since the last AMD Socket A smouldered within a RAM melt. (Have on idea way there was a smoulder because over clocking was not invoked!) This query is interesting because almost all of the new processors sold are sixty four bit. Flash which is still alpha or beta and a couple of Google applications have not been fully embraced upon the x84-64 architecture which is problematic!
Why? This is just a random post that might be locked or deleted but an individual has been disturbed with the lack of x86-64 application support within Linux considering Unix operating systems have been upon this architecture for an extended period compared to Microsoft operating systems. Citing that SUN or now Oracle possessed the sixty four but architecture when this individual started to dabble within the I.T. industry many years ago. There is still substantial grief that Redhat did not purchase SUN for the hardware.
I'm here to lend your support again. I just install "VirtualBox" in Fedora12, but would like to recognize USB ports, how can I do this?

On the server machine when I do port scan with nmap I see the following result:

Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1.
Interesting ports on localhost (127.0.0.1):

But when I try to do telnet from an external machine, e.g:
telnet <IP of host> 53
I get:
Connection refused
telnet: Unable to connect to remote host
I also did a port scan with a tool on an external machine but port 53 and 25 weren't listed as opened ports. Also CheckDNS.net on the server returns "Connection reset. Probably DNS server is offline". I am 100% sure that named and sendmail are running. When I do a ps -aux I see:

View 1 Replies View RelatedI'm working on a Linux (fedora) based arcade dance machine using a game called Stepmania. I've got it all up and running and i'm trying to get it to work with two dance pads.
It detects the dance pads fine and they work well, the only issue is that when the machine is turned on it seems to randomly pick which pad is /dev/input/js0 and which is /dev/input/js1
What this leads to is the pad on the left controlling the character on the right & vice-versa. So I was wondering if there is any way to tie or map the joystick to a particular USB port so they always stay where they should ? Or is there another way this could be accomplished ?

A few months ago I installed Ubuntu 9.10 on my girlfriends laptop, on her request, as she didn't like Windows any more. Since then the internet connection periodically slows down due to too many open ports/connections. Always when this happens I call our ISP and usually there are around 80-200(!) active connections to various IP's.
She is not downloading torrents or anything.
She only uses Firefox and a few open tabs as people do.
Skype is open.
Wireless internet connection.
I am thinking either Ubuntu is updating more or less constantly or the ports/connections aren't closed "after use".
Does any body know how to enable ports in ubuntu 10.04?
