When trying to run a program, from Gnome terminal, for a device connected to /dev/ttyS0 (COM1), I get a segmentation fault. I think the terminal may not want to leave the connection open for some reason. Do I first need to mount the device somehow?

How can I find out list of multicast addresses and port in use?"netstat -ng" only gives list of multicast addresses that have been joined, it does not give port number.I have several hundred servers running application that listens to several multicast addresses on different ports. I want to write an audit script and get the list of multicast address and port numbers.

View 1 Replies View RelatedIf the filesystem is mounted with noatime option does it influence find -atime behaviour? I tested and it looks that find is able to see access time but why should it if mounted with noatime? Or maybe it depends on the type of filesystem (I`m using XFS)?EDIT: Looks the answer is [URL]htmlIf a file system has been mounted with this option, reading accesses to the file system will no longer result in an update to the atime information associated with the file like we have explained above. The importance of the noatime setting is that it eliminates the need by the system to make writes to the file system for files which are simply being read. Since writes can be somewhat expensive, this can result in measurable performance gains. Note that the write time information to a file will continue to be updated anytime the file is written to.

I'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 ?

I am new to Linux. I am installing oracle OBIEE 11g on Linux Red Hat 5.6 64 bits and I got stuck at ports not open error.

How do I open ports on my server.
How to separate sftp and ssh and run on different ports.
i.e.
a) sftp on port x
b) ssh on port 22
I searched from the web and there are no detailed instructions. They suggested something like separating sshd_config into two files (file A and file B) and run two instances. Each instance points to its configuration file.
However, they didnt write down the detailed procedure of:
a) how to modify file A and file B (i.e. which line should insert specific commands)?
b) how to run two instances?
c) how to point each instance to its config file.

I find it strange that fdisk sees the drive but mount doesn't.
I just installed pysdm so I could configure what drives mount on boot, and now when I go to access my external harddrive, this is what I get:
Unable to mount Hard Drive
Error mounting: mount exited with exit code 1: helper failed with:
[mntent]: line 11 in /etc/fstab is bad

So, I plugged in two hard drives to my server. I started with two, an IDE and an SATA. Then I plugged in another SATA and an external SATA using a PCI controller card.
I currently only have command prompt (Putty) access. How can I set the drives up to be usable. They were on another server that died.
Since I installed Debain Squeeze with KDE (for more than a month), there is something I cannot explain to myself. 5-10 minutes after bootup my hard disk begins to work very intensely. Then, after 2-3 minutes it comes back to its normal operation. Using "atop" I found out that the first process that squeezez my HDD is "find". Then, a little bit later, mount.ntfs-3g appears. Both do what they do, then exit and everything's back to normal. What I suppose, is that that something is searching, first on the Linux partitions, then on the ntfs partitions.
Does anybody know what is this phenomenon related to? Or at least, how could I find out. Ah, and to avoid some basic troubleshooting questions: I have 3 GB of RAM, so no swap is needed. And I repeat: it's find and mount.ntfs-3g that use the HDD.
How do I verify that my 6 GB/s SATA ports are working under Linux?
Linux detects the ports, and I can use them for disks but I would like to figure out if they are using a 6 GB/s controller/driver instead of the slower, more common speed.
