I am getting following assertion in my application:
pthread_mutex_lock.c:275: __pthread_mutex_lock: Assertion `(e) != 35 || (kind != PTHREAD_MUTEX_ERRORCHECK_NP && kind != PTHREAD_MUTEX_RECURSIVE_NP)' failed.
all my mutexes are of type PTHREAD_MUTEX_RECURSIVE and as per all the man pages/tutorials, EDEADLK error is to be returned for mutex of type PTHREAD_MUTEX_ERRORCHECK ONLY.I really should not be hitting this assertion.Would some kinda weird memory corruption be causing this? Or is there something more to it that I am not aware of.I am using linux kernel 2.6.2, glibc 2.5 on PPC.
we have a multi threaded program on Linux where one thread is waiting on poll() system call with event set to POLLIN, & another thread has closed the same socket fd (which is passed to poll) , but the poll() did not return, is this the expected behavior? From man page of poll we found that the poll should return POLLNVAL if the socket fd is closed, is my understanding correct or is there any bug in the poll()?In Solaris we observed that the poll system call is returning with POLLNVAL if the socket is closed.

Lets say I have a site "Website1.com"
On that site I want to run a little javascript that verifies that the site was accessed as "Website1.com" and not "dev-Website1.com"
If it was accessed correctly, nothing happens. If it was accessed incorrectly, it displays an error saying "You are trying to access this site incorrectly."
What is the simplest way to accomplish this?
i m using atoi() to convert char value to int. and then passing that int as a swtich variable.switch goes in a case and exectuing that particualr function but returning 0 value....for example: i am finding no of process() and system up time().when switch program goes in system up time it gives right values means correct no of days, hrs , min and sec but when it goes in no of process() it gives 0 answer.

I've had all kinds of different results and problems, but I've never been able to successfully log into multiple servers, though the first server in the list most times works okay (though might not on this iteration). I'm a bit hack and slash and I would be very greatful not only for a solution, but any tips on how I should have done this and places where I could clean up my code.
I have a directory that has a bunch of files and directories under it that I need to correct the filenames of. In fact, I plan on running this as a cronjob to keep checking filenames for certain characters. I want directories and filenames with spaces or pluses (+) to have those certain characters replaced with underscores (_). I know that this will involve sed but I'm not sure what else. A simple shell script would handle it.

Im doing a sudoku-solver as a school assigment in Java. It is supposed to solve both 6x6, 9x9 and 12x12 boards.Im pretty much done with my algorithm(brute force), but I'm having a hard time figuring out how to calculate the right Box for a Square. I found this snippet:
Code:
// calculate BoardPos for index, where index is 0..80
void loadBoardPosFromIndex(BoardPos &pos, int index) {
pos.index = index;
[code]...
This works on 9x9 boards, but I really dont get the math behind this, and how I can create a generic rule for both 6x6, 9x9 and 12x12 boards.

View 3 Replies View RelatedI found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

I have been searching for 90 minutes for something that I "think" should be fairly easy. I'm pretty new to Bash Scripting so I could be completely wrong. Then again it may be a weird request to even need something like this. But here it is.I have a script written to convert data from one of our software version to another. The only thing I need to add to it is a "check to make sure the user running the script is in the /tmp directory".

Sleep button works just fine. /etc/acpi/sleep.sh from console too.

I noticed that it always goes to sleep again when I wake up laptop by opening the lid. For example if I run /etc/acpi/sleep.sh, pm-suspend or press the sleep button laptop goes to sleep, then i close the lid and when i open it back - the problem occurs.

View 2 Replies View RelatedI have a linux box, which was given to me by a company with 3 dedicated IP addresses. My goal was to setup ssh tunnels on all three dedicated IP Addresses.
Via Putty, i am successfully able to create a tunnel to the box's on IP1 IP2 and IP3 - that is i can make incoming connections on all three IP's.
However, my problem lies when i attempt to USE the tunnel. AIn all instances, regardless of the IP i actually tunneled into the box with, it returns IP1 as an outgoing connection, i.e if i setup IE to use the tunnel, it will return my IP as IP1, even though i have created the tunenl via IP2/IP3.
What id liek to accomplish is that when i create a tunnel via IP1, then outgoing connections go via IP1, and when i create a tunnel via IP2, then outgoping connectiosn go via Ip2 etc.
After discussing this with a colleague of mine, he infomed me he had the same problem at one point, and that some configuration on the box was required - however he was unable to recall.
I'm building a very small netbootable client, using a stripped down custom kernel and busybox v.1.18.4 (stable) with the embedded ifconfig and udhcpc applets
after startup, the initrd is loaded, and the proc, sys, dev and pts folders are properly created and mounted.
/proc/net/dev properly contain eth0 as an ethernet device.
in the init script I execute a background call to udhcpc passing the dhcp.script properly to udhcpc, and dhcp.script is then executed when the bound event occurs.
what I cant get past is udhcpc is passing back the interface evironment variable as etho0 (thats, 'eth' lowercase 'o' and a zero '0', when it should be passing 'eth0', thats 'eth' and zero '0')
I know I could hardcode the eth0, but i was hoping for a somewhat smarter system.

I have a situation where I have two DNS servers - a BIND one for our Unix hosts and a Windows Server DNS one for the Exchange and other Windows hosts. I set up the BIND server to slave from the Windows one, which it seems to do just fine.
Windows DNS has entries like "_gc._tcp.domain.local" in it, which are needed for domain logins, etc.
However, when I try to use nslookup on those entries, it fails when querying the BIND server. When I do a domain transfer with dig, I get all the answers I expect.
This failure means that the Windows boxes can't query the BIND server for the answers they need. By default, from DHCP, it is the BIND server they get, so that's a big problem. If I manually switch their DNS to the Windows server, it works perfectly.
