This is a binary distribution of sunrpc-4.0 compiled for Linux.
|
||||
|
||||
It is the RPC (Remote Procedure Call) and XDR (eXternal Data Represenation)
|
||||
library together with support programs. The original freely distributable
|
||||
sunrpc was written by Sun Microsystems for BSD systems. I did not include
|
||||
any secure_rpc stuff because I don't think it is very widely used and the
|
||||
secure_rpc distribution didn't include the necessary DES encrpytion.
|
||||
|
||||
I did a fair amount of hacking to get it to work with Linux. Plus
|
||||
I fixed a couple of ugly bugs.
|
||||
|
||||
The archive includes:
|
||||
|
||||
README this file
|
||||
etc/rpc RPC services files
|
||||
etc/portmap RPC portmapper daemon
|
||||
etc/rpcinfo RPC status reporting program
|
||||
usr/bin/rpcgen RPC protocol compiler
|
||||
usr/bin/rstat RPC sample remote status program
|
||||
usr/lib/librpclib.a RPC and XDR library
|
||||
usr/include/rpc/* RPC library include files
|
||||
usr/include/rpcsvc/* RPC protocol descriptions and header files
|
||||
usr/man/man[1358]/* RPC man pages
|
||||
|
||||
The binaries were compiled with version 4.1 jump-table libraries.
|
||||
They will not work with Linux TCP/IP 0.8.1 without the kernel patch at the
|
||||
end of this file. I have sent it to Ross and he may include in the next
|
||||
release. Even if you don't apply the patch you can still use the library
|
||||
and header files for porting.
|
||||
|
||||
You must have a /usr/etc/inet/protocols file for some of the programs
|
||||
to work. Here is one I cooked up:
|
||||
|
||||
$ cat /usr/etc/inet/protocols
|
||||
# protocols - standard well defined IP protocols
|
||||
ip 0
|
||||
icmp 1
|
||||
ggp 2
|
||||
tcp 6
|
||||
egp 8
|
||||
pup 12
|
||||
udp 17
|
||||
idp 22
|
||||
raw 255
|
||||
|
||||
Also make sure you have the following lines in /usr/etc/inet/services:
|
||||
|
||||
$ grep sunrpc /usr/etc/inet/services
|
||||
sunrpc 111/tcp
|
||||
sunrpc 111/udp
|
||||
|
||||
Here is how you use the portmapper. In your rc/rc.local/rc.net or whatever
|
||||
put the following fragment after you configure TCP/IP:
|
||||
|
||||
if [ -f /etc/portmap ]
|
||||
then
|
||||
echo "Starting portmapper..."
|
||||
/etc/portmap
|
||||
fi
|
||||
|
||||
Then if you have TCP/IP in your kernel and have applied the patch you
|
||||
can say:
|
||||
|
||||
$ /etc/rpcinfo -p
|
||||
program vers proto port
|
||||
100000 2 tcp 111 portmapper
|
||||
100000 2 udp 111 portmapper
|
||||
|
||||
If you get "Connection refused" you probably haven't applied the patch.
|
||||
|
||||
If all is well you can go to another machine on the net and say:
|
||||
|
||||
$ /etc/rpcinfo -p your-hostname
|
||||
program vers proto port
|
||||
100000 2 tcp 111 portmapper
|
||||
100000 2 udp 111 portmapper
|
||||
|
||||
This is not very useful unless you have some RPC services to provide.
|
||||
I have not yet finished porting rstat_svc which is very BSD-kernel oriented.
|
||||
When I do, you will be apply to run Sun's Performance Meter to display
|
||||
information about your Linux machine.
|
||||
|
||||
I will be releasing my port of a mount daemon and nfs server daemon shortly.
|
||||
|
||||
You don't need to run the portmapper or apply the patch to use RPC services
|
||||
on other machines. The only programs in this distribution that can do that
|
||||
are rpcinfo and rstat.
|
||||
|
||||
