read function
Hello all
In UNIX i wrote a program which simply establishes a conncetion with another system, using write system call i wrote a message to the server from client and from the server i send another message, for the second time i send a mesage using write system call to the server, when i send a message from the server using write system call for the second time iam not able to read in the client , the client waits in an infinite loop. what is the problem in using repeated read or write calls subsequently
plz explain my doubt

I use fopen, fscanf, fclose to read a file. It can work well. since many files should be read, a function is created with the same code. But in the function, fscanf can not work well.
for example, the first line of the the file is: > filename
but the fscanf will give: 207/23/eee/34

net::proxy::connector::dual
Net::Proxy::Connector::dual(3pm) User Contributed Perl Documentation Net::Proxy::Connector::dual(3pm)
NAME
Net::Proxy::Connector::dual - Y-shaped Net::Proxy connector
DESCRIPTION
"Net::Proxy::Connecter::dual" is a "Net::Proxy::Connector" that can forward the connection to two distinct services, based on the client
connection, before any data is exchanged.
CONNECTOR OPTIONS
This connector can only work as an "in" connector.
The "server_first" and "client_first" options are required: they are hashrefs containing the options necessary to create two "out"
"Net::Proxy::Connector" objects that will be used to connect to the requested service.
The "Net::Proxy::Connector::dual" object decides between the two services by waiting during a short timeout. If the client sends some data
directly, then it is connected via the "client_first" connector. Otherwise, at the end of the timeout, it is connected via the
"server_first" connector.
o host
The hostname on which the connector will listen for client connections. Default is "localhost".
o port
The port on which the connector will listen for client connections.
o server_first
Typically an "out" connector to a SSH server or any service that sends a banner line.
o client_first
Typically an "out" connectrot to a web server or SSL server.
o timeout
The timeout in seconds (can be decimal) to make a decision. Default is 1 second.

ACKNOWLEDGMENTS
This module is based on a script named sslh, which I wrote with Frederic Ple "<sslh@wattoo.org>" (who had the original insight about the
fact that not all servers speak first on the wire).
Frederic wrote a C program, while I wrote a Perl script (based on my experience with connect-tunnel).
Now that "Net::Proxy" is available, I've ported the Perl script to use it.
