Networking :: Can't Bind Send Socket: Address Already In Use
Feb 23, 2009I am currently trying to get a B.A.T.M.A.N mesh network up and running. the thing uses UDP port 4305 for broadcasting to nearby nodes and it seems this port is closed or used by something else.
now i have tried to open this port with commands like
Code:
iptables -A INPUT -p udp --dport 4305 -j ACCEPT
iptables -A OUTPUT -p udp --dport 4305 -j ACCEPT
it still gives me the same error saying the socket cannot connect.any way for me to scan that udp port, see what is blocking it and open the thing up ?

Programming :: Send A UDP Msg Across A Socket?
Jan 24, 2011Has anyone had an issue with gdb not being able to send a UDP msg across a socket?
I have ComponentA sending a msg to ComponentB utilizing gdb. ComponentB gets the msg. ComponentB sends a msg to ComponentC. ComponentC does stuff to the msg and sends a msg back to ComponentB using gdb.
ComponentB never seems to receive the 2nd message.
If I don't use gdb the messages Tx and Rx without an issue.
I'm flying blind without gdb to figure out a different bug.

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

OpenSUSE :: Traceroute Broken In 11.4 - Unable To Create ICMP Send Socket: Permission Denied?
Apr 5, 2011Code: # traceroute -I 69.12.32.2 Note: the -i and -I options were exchangedfor compability with LBL traceroute Use -I for ICMP, and -i <ifname> to specify the interface name unable to create ICMP send socket: Permission denied Note that the command was done as root. This worked in 11.3.
And yes, it works without the "-I". But it should work with the "-I". One shouldn't have to boot into Windows, just to run "tracert" there.
Networking :: Multiple FTP Upload Socket Error "Connection Reset By Peer: Socket Write"
Jan 31, 2010I 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?

Server :: Send And Receive E-mails To And From An Array Of Virtual Domains?
Jan 4, 2010I've set up a fully functional e-mail server and can send and receive e-mails to and from an array of virtual domains without a problem. The only hiccup I have is that only root is able to send e-mails via mutt. I have not stipulated a sendmail line in the mutt configuration so it's sending e-mail with default configuration. How can I get it so that all users on the server can send outgoing e-mails via mutt?
Update: Solved this by following this http://inmyplace.info/2008/05/07/pos...ission-denied/
Programming :: Send File Through Raw Socket Using C Programming
Jul 23, 2010I am currently doing a research on video transmission over wireless LAN. I tend to transmit my offline file (xx.svc) from server to client.It may sound stupid (since I have a very little knowledge about c programming and raw socket), but my biggest challenges is that when I want to write the file to the buffer, how actually to define/include the file at the programming coding? where I need to locate the file? Is it at the same folder with my c programming, or somewhere in the linuxinclude folder?
Can anyone just give a simple example on how to include a file and write it into a buffer before send it through raw socket.

Programming :: Setsockopt : Socket Operation On Non-socket Getting Error?
Mar 30, 2009im 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().

Im just trying to set up a server to pass messages from a client to it a viceversa. Here is the code:

View 1 Replies View RelatedNetworking :: How To Avoid Loopbacking For UDP Socket
Aug 26, 2010I am facing some problem with loopback on UDP sockets. is there anyway by with we could avoid loopbacking of a UDP datagram destined to same IP address, and instead force it to go all the way till NIC and then come back to the socket.
The problem is, we have some piece of code written at driver level, and we want each and every packet to hit that code on its TX and RX path. But if src and dest IPs are same, packet loops back from the IP stack itself, without hitting the driver code.
Can we modify the characteristics of a UDP socket, such that each and every packet has to go through NIC interface, thus avoiding loop backing when the src and dest IPs are same?

Ubuntu Networking :: Windows Socket Connection ?
Mar 17, 2010I am trying to connect with Winsock Windows sockets from a PC running Windows XP with a utility program that enables a dialogue over sockets. I have the listener running on Ubuntu on Port 6330. I can telnet to the listener and interact from both the Ubuntu desktop and the XP PC. But my utility program using Winsock is unable to connect. I have no firewalls impeding this. Maybe there is a better vehicle than the Windows Winsock.dll? I dont need network file access, just TCP ports/.sockets.

Apr 18, 2010Have a question regarding the implementation of TCP keep alives.
If I enable the option of keep-alives on a TCP socket, is there any way that my application can get the response to the keep-alive back from the kernel. Basically, I have a 'select' blocking on a socket on which I have enabled keep-alives. I need to know if select would unblock if a response to a keep-alive sent by the kernel is received on the socket.
