Exercises: Sun Remote Procedure Call
Before asking questions regarding this exercise, please review the
lecture notes of Week #01 and #02 as well as the documentation linked to
on this page.
Sun Remote Procedure Call
Use Sun RPC to implement a simple file server. The file server should
implement simple functions that allow clients to read from and write to
files hosted on the server. It is up to you whether you want to make
the server stateful or stateless.
Developing software using sun RPC
- Write an XDR interface definition. For example:
> cat date.x
program DATE_PROG {
version DATE_VERS {
long BIN_DATE(void) = 1;
string STR_DATE(long) = 2;
} = 1;
} = 0x31234567;
- Generate stub code, client and server templates, and a Makefile (on
Mac OS X rpcgen doesn't generate a Makefile):
> rpcgen -Ca date.x
> ls
Makefile.date date.x date_clnt.c date_svc.c
date.h date_client.c date_server.c
- Edit the client and server templates (date_client.c, date_server.c)
- Build:
> make -f Makefile.date
- Run the server
> ./date_server
(Note: On Mac OS X I found that I had to start the server as root with sudo)
- Run the client
> ./date_client localhost
More documentation
A nice set of slides that gives a good overview of XDR data types and
other RPC programming issues.
If you want more detailed information, Part 2 of the
Sun Network Interfaces
Programmer's Guide has all the information you'll ever want about RPC
programming.
