Hello I need to submit this exercise until the end of the day of the 18th of may.
I have to write a code using Language C (Fedora, Linux). If requested I insert also my student number: 1230065.
I also insert this code sent by the professor to check if the code works correctly:
#!/bin/bash
if [[ $# -eq 0]] ; then
echo 'Utilizao:' $0'nmero_de_estudante'
exit 0
fi
CFILES=$(echo -e "ex2_clt.c
ex2_srv.c
ex3_clt.c
ex3_srv.c
ex4_clt.c
ex4_srv.c
ex5_clt.c
ex5_srv.c
ex8a.c
ex8b.c")
OIFS="$IFS"
IFS=$'
'
for file in $CFILES
do
ls ${file} &>/dev/null || echo Ficheiro \"$file\" no encontrado.
execfile=${file%.c}
ls ${execfile} &>/dev/null && ( grep "$1" ${execfile} &>/dev/null || echo Verifique se faz a impresso solicitada em \"${file}\")|| echo Ficheiro \"$execfile\" no encontrado.
done
IFS="$OIF"
Here it is the exercise:
Exercise 2
a) Implement a client/server application using TCP/IP based communication according to the
following protocol:
After establishing the connection to the server, the client sends the contents of the
file whose name is specified as the first argument of the command line.
Upon accepting the connection, the server should write all the received data (i.e.,
the file contents sent by the client) to a temporary file. The temporary file is created
and opened using the following sequence of instructions:
For an example on file manipulation, see the program provided in simple_clone.c.
b) Analogously to I-5), ensure that the server can handle multiple clients simultaneously.
Thank you very much, regards
Lorenzo.
