Description
Write a program that implements the SLIP protocol (RFC 1055) to copy
data from one process to a second process via a socketpair. Note that,
although it does not provide great performance, this version of SLIP
writes (and reads) just one byte at a time.
The original process should establish a socketpair for the two processes
to communcate and then create the second process. The first process should
then read a file named “infile” and pass the contents to the second process
using SLIP via the socketpair. Use the RFC1055 *maximum* packet size of
1006 bytes. However, do not pad to have all packets be the same size.
The second process should receive the data and create a copy of it by
writing the received data into a file named “outfile”.
Note that infile may contain any 8-bit value in each byte, i.e. the bytes
will not all necessarily be printable characters. Each time that your
program sends an ESC, ESC_ESC, or ESC_END character, it should print a
one-line message notifying the user; it should NOT print a message about
sending simple END characters.
Testing will go something like this:
rm -rf infile outfile
cp some_file infile
./p1
cmp infile outfile # <– works for binary also
Submitting the project for grading:
You should use turnin to submit a tar file containing all of the required
files, including source code, makefile, etc.
The project should compile and link as p1.
To build the project, I will cd to my directory containing your files
and simply type:
rm -rf p4
rm -rf *.o
make
