OpenSUSE :: Grep Hangs On Sockets?
Jun 6, 2010
Here's a silly question: suppose I want to "grep" an entire directory. Real life example: we reconfigured our mail server to a different IP address, so I needed to search for each occurrence of the original to make sure they'd all been changed.
A simple
Code:
grep -i -l -r "192.168.1.200" *
... works great until it hits a socket. This particular mail server has sockets scattered at random through the directory. When grep hits one of these, it hangs.
I've tried every command line option I can think of it to force it to ignore these sockets, but to no avail. Any of you Grep Gurus out there want to give me a hand?

I was logged in as root, made some changes to my users and think I may have inadvertently changed root somehow. Ever since then, my machine runs just fine, I can sudo, Yast, etc without any issues. (Root password is fine) but when I try to log in as root, the system changes the screen display, as if it's going to login, then returns me back to the login prompt without error. If I "ctl+alt+F1", I drop out to the console and can login as root, but cannot startx because the display is already in use.... So, I removed the .X0-lock, but still cannot get the GUI to load. (after running rm /tmp/./X0-lock, I get a fatal error, "can't establish any listening sockets..." "Ctl+Alt+F7" brings me back to the GUI where I am logged in as myself in Gnome) if I login with my user account, everything runs fine and all is well.

I need to kind of grep within grep. My input file would be something like:
[Code]....
and I need to find the first occurrence of hello before MY PATTERN (hello 9008 in this case), so the output should be:

works fine on a FAT32 dsk:
Code:
fgrep -iRn -C 2 'print' *.txt
---also recurses one level and displays all kinds of data
---------------------------------------------------------------
in root / ext4 directory:
Code:
fgrep -iRn -C 2 'print' *.* or fgrep -iRn -C 2 'print' *.txt
---displays msgs:
fgrep: *.*: No such file or directory
and
fgrep: *.txt: No such file or directory
I am probably missing something very basic.recursive does not seem to work from root directory.Is this (as they used to say) a feature? This is on an 11.2 system, upgraded to 11.3 (ran zypper verify to verify. According to it.. all is well).

Is there any way to implement a simple ping script in C (unix)? I'm programming simple OpenWRT scripts.
I have found some examples of ping in C:
[URL]
However, nothing happens, nothing is sent.
When I look at the code, in the portion where the socket is created, I can see that the socket is not binding to any interface:
Code:
if ((sockfd = socket(AF_INET, SOCK_RAW, IPPROTO_ICMP)) == -1)
{
perror("socket");
exit(EXIT_FAILURE);
}
setsockopt(sockfd, IPPROTO_IP, IP_HDRINCL, &optval, sizeof(int));
Instead, it uses "setsockopt" to set some options.
My guess is that it is trying to send packets over the eth0 interface instead over the wl0 (wireless) interface (which is the one I want to use to send pings).
Now, my question is: Is there any other way to send pings in C by binding to an interface?

I need to create a C/C++ program in Linux that succeeds in detecting how many tcp-sockets and what tcp-sockets are created by the other processes in the system in a particular time interval (e.g., the interval time this application is running in). Then, I'd need to get some information like local/remote port number and local/remote ip address of each of these sockets.

I am struggling a little on how to best approach this problem. I have wrote a server program that runs via xinetd, that obviously spits out data at the client end. Fairly straightforward stuff?There is a point in my server code where I need to display an image/gui i.e something that runs on X11 that prompts a user to perform a task on the display connected at the the server side.So far I have written a test program that displays some text at the client end and then launches the browser at the server end. I have also set the following export. Code: export DISPLAY=:0 and then goes on to launch my web browser. Works great when ran locally on the server and when I remotely telnet in to the server and run the code.
However when I try to run the same piece of code as a xinetd service the export seems to have zero affect and the client terminal window displays errors associated with there not being a X11 server running.The code launches fine when I create a socket to serverip:6556 it just the ability to display gui programs to another display that does not seem to be working.

The problem started when I noticed I couldn't upload to people using a torrent downloading program, the program listened on port X and when I sniffed on the same port I saw that syn's are forwarded correctly from my nat to that port but the program doesn't relate to those packets. Then I listened with NC, and even on another port nothing is being answered to those syns packets.

Can someone help me with this problem,trying to send a packet,using tcp/ip,the packet should look like this:
Code:
field 1: SOCKS protocol version, 1 byte (0x05 for this version)
field 2: status, 1 byte:
0x00 = request granted
0x01 = general failure
0x02 = connection not allowed by ruleset
0x03 = network unreachable
0x04 = host unreachable
0x05 = connection refused by destination host
0x06 = TTL expired
0x07 = command not supported / protocol error
0x08 = address type not supported
field 3: reserved, must be 0x00
field 4: address type, 1 byte:
0x01 = IPv4 address
0x03 = Domain name
0x04 = IPv6 address
field 5: destination address of
4 bytes for IPv4 address
1 byte of name length followed by the name for Domain name
16 bytes for IPv6 address
field 6: network byte order port number, 2 bytes
and this is my code:
Code:
int domainLen = strlen(domain);
char reply[domainLen + 7];
reply[0] = 5; // version
reply[1] = 0; // succed
reply[2] = 0; // reserved
reply[3] = 3; // its a domain
reply[4] = domainLen;; // lenght of domain
for(int j = 0; j < domainLen; ++j)
{
reply[j + 5] = domain[j];
}
reply[5 + domainLen] = 80; // port
reply[20] = '�';
Send(reply, sizeof(reply));
domain is "www.google.com". Am I doing it right ? I dont know much about bits.

There is a transient bug in my code which I just can't catch.
The basic idea is this. I have a multithreaded server and two thread pools, the IO pool and Worker pool. The main server thread listens to incoming connections. When it gets one, it dispatches a thread from the IO pool to read the socket. An IO thread reads the socket. If there is data, it invokes a thread from the Worker pool. This thread then finishes off the processing including closing the socket. The code follows.
Before I show the code, let me tell you what's happening when I am testing it. I have a client program which has about 30 threads, each opening a separate socket connection with the server. Each sends a request which the server responds to. Sometimes I have all the threads finish in a zip. Sometimes both the client and the server hangs. And yet at other times, the client gets a connection refused message.
Now the code. I have omitted some of the nitty-gritties, including possibly variable declarations. I'll post them if it's required.

I am trying to install Ubuntu 10.10 x64 on a HP Pavilion p6565uk.
My PC is x64 compatible, although ubuntu will not install.
I don't get to any gui, it says ubuntu will continue install in 5 seconds, at 0, nothing happens. The CPU light is flashing, but nothing happens.
After about 10 minutes, it reboots, but when the HP splash screen shows (Before the boot selection screen) it just hangs. I have to do a hard shutdown to boot back up.
I am using wubi for install.

I've been using OpenSUSE (11.2) and ssh to access my Ubuntu Server (8.04). The problem is that when I give the shutdown command to turn off the server (sudo shutdown -P now), OpenSUSE hangs and I can't close bash and the computer locks up. I then need to turn my OpenSUSE box off by pushing the power button. Any idea what might be causig this?I'm not sure if this is the right place to ask this question because I don't think this is a bash problem but I wasn't really sure where to ask this question.

After my first installation/ version of Ubuntu 64, I performed a netstat and noticed I did NOT have any Active UNIX domain sockets as I do now. After doing some research, I found this is related to MYSQL and server services which I am in no need of running and nor do I want to run if not needed. So exactly what are these services used for, which app is creating this and why?
Is it possible to remove the app or processes if they are not needed? Killing these connections every time they attempt to establish would be rhetorical.

I am doing a project where 2 clients connect to server and communicate (chat) and transfer data one after other using sockets. I have working code for this in C language. Now our main aim is to create a communication link where two clients transfer multiple streams data parallely. To be more precise i want to transfer images files and audio files parallel at same time, so is it possible to send data parallel using one socket connection?

I have a C program which does.
1. Creates a UDP socket
2. Send the UDP Request packet to the TFTP server.
3. If the TFTP server is not listening in the 69 port, the remote machine send an ICMP ("Port Unreachable") message.
Is there a way to receive a notification from the Linux kernel on receipt of an ICMP packet to the created UDP socket.

if(sockfd[i] < 0) error("(MAIN) - Error openning socket 1");
port_num[i] = portno;

I am using the API libpcap in order to filter the traffic of the port 53 from my PC ro other PCs, in other words the DNS traffic.I want to get more information about the DNS traffic that is being sent to the DNS server, in other words the queries. So far I have no idea how to read the information data or payload of the UDP package in order to read the content of the traffic for example if there is any PTR, A, MX, etc Resource Record.According to the RFC 1053 there is a header that is possible to use in order to easily get this info.
