I started my computer with a problem that all of the windows without title bars. I tried to logout my laptop, and the problem was solved. I opened one terminal window, type 'who', founded that i was login the system as 'tty8'. That was really funny, I know that if i login the system normally i may login the system as 'tty7'. why i login as 'tty8' when logout one time? My edition is ubuntu 10.04.

View 2 Replies View RelatedI've been having a lot of trouble with getting wireless networking devices to work. I guess I have a lot of company, since mfrs don't seem to be very interested in supporting Linux.It seems that one common symptom is that, when I try to "Ping" using the Terminal, I get "network is unreachable".Does this mean anything specific, or is it a general output whenever the network is not carrying on two way communications? Does it mean that the wireless interface is down? Does it mean that the wireless hardware is not transmitting? Not receiving?

I have been using gcc to compile C programs.
I want to know what exactly is the meaning of Compiling a C program.
I checked
cc -S prog.c
will give an .S file and if you analyze the hexdump I saw some assembly instructions.
So what does the compiler do which is not required in case of interpreted languages?

I'm working on a friend's Samsung R530, Intel Core i3 3330M (T430) processor. It had Windows 7 installed, which crashed so I'm trying to recover the files before installing Ubuntu (the recovery partition is gone, there was no facility for making recovery disks and Samsung won't send any out). I put in the Live CD for 10.04 which took ages to load and then gave me the following error message:
udevd (90): worker (181) unexpectedly returned with status 0x0100
udevd (90): worker [180] failed while handling '/devices/pci 0000:00/0000:00:00:00'
which was repeated for [182] and [230] then it all went blank for ages then I got a message saying eject the cd and press enter, just like you do at the end of an install. However, I didn't get an option on whether to boot from the cd or install ubuntu. anyone got any clue what the error message means? and am I correct in thinking that the cd tried to install ubuntu? I've tried 3 different live cds, all of which have previously worked on other machines so I'm pretty sure it's not a cd issue.
But I can't get a single one of them to boot from cd and all throw up the same error messages, except the 9.04 cd, which just hangs. Have also tried a USB live image and got a disk error message. When I try booting from the HDD I get OS not found, boot from cd. Which is not entirely unexpected because of the previous problem with windows but it also seems that Ubuntu hasn't actually installed, or if it has then there's been a problem and it hasn't done it properly.
I'm using openSUSE 11.3. In the Yast2's module: Software Management, in the search tab, there is a column called: "Installed (Available)", It usually shows the current installed version of the package, but sometimes its blue, red or most of the times black. What does the color mean?

View 7 Replies View RelatedI've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

View 9 Replies View RelatedI just focus on the filter table:
First : What is the meaning of the "opt" parameter?
Second : What is the aim of the "destination" for the INPUT chain ? The destination must be the ip of machine, isn't it ? I must put anywhere (except if my ip is fixed), right?
Third : The same : What is the aim of "source" for the OUTPUT chain?
Fourth : What are the following rules?
Code:
target prot opt in out source destination
ACCEPT udp -- eth1 any anywhere anywhere udp dpt:bootps
ACCEPT tcp -- eth1 any anywhere anywhere tcp dpt:bootps
ACCEPT udp -- eth1 any anywhere anywhere udp dpt:domain
ACCEPT tcp -- eth1 any anywhere anywhere tcp dpt:domain
eth1 is my wireless interface and I use it on a local network, my comp being the gateway.I suppose that "domain" is linked to the dns and it must be open if the devices on the lan specified my comp as their dns, right? But what about bootps?
I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.
Any idea how I could remap them to the original meaning?
