Hello I need to submit this exercise until the end of the day of the $18$th 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 'Utiliza$$o:$\text{'}$ $$0\text{'}$n$$mero$\_$de$\_$estudante'

exit $0$

fi

CFILES$=$$$($echo $-$e $"$ex$2\_$clt$.$c

ex$2\_$srv$.$c

ex$3\_$clt$.$c

ex$3\_$srv$.$c

ex$4\_$clt$.$c

ex$4\_$srv$.$c

ex$5\_$clt$.$c

ex$5\_$srv$.$c

ex$8$a$.$c

ex$8$b$.$c$")$

OIFS$="$$IFS"

IFS$=$$$\text{'}$

$\text{'}$

for file in $CFILES

do

ls $$\{$file$\}$ &$>/$dev$/$null $||$ echo Ficheiro $\backslash "$$file$\backslash "$ n$$o encontrado.

execfile$=$$$\{$file$\%.$c$\}$

ls $$\{$execfile$\}$ &$>/$dev$/$null && $($ grep $"$$$1"$ $$\{$execfile$\}$ &$>/$dev$/$null $||$ echo Verifique se faz a impress$$o solicitada em $\backslash "$$$\{$file$\}\backslash ")||$ echo Ficheiro $\backslash "$$execfile$\backslash "$ n$$o 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.
