Ubuntu Networking :: Can't Identify Process/Unbind Socket Blocking MongoDB
Mar 27, 2011
I'm running Ubuntu 10.10 64bit, and I'm a newbie when it comes to networking.
My issue is that there seems to be a socket bound to a port blocking MongoDB from accessing it's usual port 27017. The strange thing that it was working just fine until recently and I can't figure out what I did to screw things up... I can make it use a different port but the reason why it can't bind to the default port and why I can't fix it is really bothering me. I've tried rebooting the machine even with nothing else running when I try to run Mongo is still blocked giving the following message:
Code:
ropes@ropes:~/mongodb-linux-x86_64-1.8.0/bin$ ./mongod
./mongod --help for help and startup options
Sun Mar 27 14:08:14 [initandlisten] MongoDB starting : pid=2718 port=27017 dbpath=/data/db/ 64-bit
[Code]....

My question is quite simple:What are type of applications where socket in blocking mode can be used ?
And where non-blocking mode to be used ??
TCP is blocking by default.

I need to write program for non blocking socket connections.I have made extensive research but could only get to non blocking READ or WRITE after the connection is established. run the program do a series of tasks (ex: counter printing time on screen) if there is request for connection, connect send or receive data.

Been trying all sorts of different things to implement a non-blocking send on a TCP server socket.As I kill the client, the server keeps blocking on the send no matter what. Am I missing something? Any other way to do that without involving any additional thread?

To see if an application is using all the cores in a system, I wanted to identify which process is running on a core at a given time. Is there any way to get that information?

I have a WA% between 50-80%.
So I have a few questions.
1. Is that WA% only disk I/O or can it include network IO?
2. How do I identify which processes are making up that WA statistic?
3. Why does iostat report 100% utilization when the drive read/write speeds are under 1MB/s?
The reason I'm asking.
My Oracle stats are saying that the drives are running at about 5MB/s right now, the WA is 55%, and the iostat -m -x is reporting the drives running at 100% utilization with a read/write rate under 1MB/s. The read speed of the drive is 98MB/s (tested with hdparm -tT when I installed the drives)
I know I have a few queries using full tables scans which I'm working on but I'd think that 100% utilization should be running at the full 98MB/s.
I want to try to identify which process (most likely and oracle one) is using the 100% utilization/55% WA.

I want to configure socket timer to release socket(port) once the connection is terminated. Do we have something in Linux OS to configure this delay to release socket?.
Any command, link or man-page anything will be helpful.
I browsed a lot but unable to find it.

I had installed Fedora 10
Below is the output of uname -a
Linux 2.6.27.5-117.fc10.i686.PAE #1 SMP Tue Nov 18 12:08:10 EST 2008 i686 i686 i386 GNU/Linux
I need to enable telnet service on it, then found xinetd and telnet-server not installed,
Then I had installed below
First I had installed Xinetd: xinetd-2.3.14-21.fc10.i386.rpm
then I had installed telnet-server: xinetd-2.3.14-21.fc10.i386.rpm
After installation I executed below commands
Service xinetd start
Chkconfig xinetd on
Chkconfig telnet on
Service iptables stop
Chkconfig iptables off
Iptables �F
After I had tried telnet localhost ----IT FAILED
when I run telnet server manually by issuing the below command
/usr/sbin/in.telnetd, I get below error
[COLOR="Red"]/usr/sbin/in.telnetd: getpeername: Socket operation on non-socket[/COLOR]
I have other system running same OS, I had followed the same steps discussed above to enable telnet, It works fine on it.

I have the following problem. I want to find out connection between process and socket. When I type to the terminal the following command netstat -anpetu so I get the following output:
[Code]....
As you can see just some connection have assign PID/Programme. How can I find out Program of this socket without PID/programme. like this 0.0.0.0:52472? Certainly I know that some port are well-known but there are a lot of unknown ports(like 8307 3350 and so on).

I need to send a java application the CTRL+F11 key sequence. Unfortunately, I don't seem to be able to do it from xfce, because it seems to be some default key binding.
Is there any way of sending that key combination to the application (either by removing it from XFCE, or by sending it via a command line directly to the application)?
I've looked in the Keyboard panel in Xfce settings, and there is no binding for CTRL+F11. However, if I try to add a new key binding, it says it is used by xfwm.

I am pragmatically trying to upload a list of files from my client machine to a proFTPd server I have running on Ubuntu. Every time I get several (around fifty) files into the transfer, I get the following error: Quote: Connection reset by peer: socket write error
I am able to remotely upload 25,000 small files of ~ 1K in size, but when I go to upload hundreds of 2-4 Mb files, I get a socket write error. Am I using up all available sockets before they can be released? If so, how do I release the sockets? If not, what does this error mean and why am I getting it?

I am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished.
1) Is it possible that the child processes that are not finished occupy the socket memory of the parent process and ultimately a point is reached where no socket memory is available to fork new child processes.
2) What is the standard limit of socket memory in linux?
3) What is the fate of such child processes (as I have mentioned above)?
4) How to debug such cases so that the exact problematic area is identified?

I'm having trouble with mongodb on debian. I'll start from the scratch: removing it.
Code: Select allapt-get autoremove --purge mongodb
Or:
Code: Select allapt-get purge mongodb
Or:
Code: Select allapt-get remove --purge mongodb
All end in the same way:
Code: Select all dpkg: error processing package mongodb-org-server (--configure):
subprocess installed post-installation script returned error exit status 102
Errors were encountered while processing:
mongodb-org-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

I'm trying to install mongodb (so called schema-less database). It requires libraries like libjs, libmozjs, spider-monkey and the like. I had an idea that installing xulrunner would provide most of that, but it doesn't do so in any nice way. I'm a bit scared to muck up my firefox/thunderbird/seamonkey system, which I suspect might easily happen if I tread wrong.

I have a device that is working on modbus protocol andI have written a small program(with block TCP read method ) to read its registers via modbus protocol.my program is working very well but except those times that I unplug the Ethernet cable or turning off the modbus gateway during programs work.at this time my program stops on recv system call (if it reach this system call exacly when I unplug Ethernet cable or turning off the modbus gateway during programs work).I changed my source to work in nonblock TCP method, at this time with the same situation my program does not stop/block on recv system call but after pluging back the Ethernet cable or resuming the connectivity situation back it reads data incorrectly .this is my code:Quote:
#define DEBUG
#include <fcntl.h>
#include <string.h>

im getting that error in my code for some reason. I compiled my code, and when i try to run this server it throws me an error on my call to setsocketopt(). The only way it can reach that part of my loop is if it succeeds when it calls sock() so I dont understand why the error says its an operation on a non-socket. Im just trying to set up a server to pass messages from a client to it a viceversa. Here is the code:
Code:
int main()
{
int socket_fd, new_socket_fd, k;
struct addrinfo hints, *server_info, *p;
struct sockaddr_storage peer_address;
code....

I was wondering if anyone might know of good reference material, books websites etc., that discuss network security issues in layman terms. I would like to set up a dedicated Linux box as a firewall and would like to have a deeper understanding of the different types of configurations that are possible. I run a dual boot system and most of the firewalls I have used on the Windows side are very confusing to me. A lot of the time they give you a pop up that informs you that some cryptically named program is trying to access the network or the internet and wants to know if I want it to or not, 99% of the time I have not idea if it is a legitimate program or not. I realize that this is probably a separate issue (knowing how to identify programs and processes that should have access from those that should not) from setting up a firewall and basic network security but I know that they are related.

I have iomega appliance, which is based on Debian distribution. There is an NFS share that I have created which is without password.Since it is without password, there are some viruses copied. I want to find out which IP address is the source of these files. In other words, I want to know which PC is copying these infected files on the NFS share.
