Hi Mark,

that's it. Maybe you have to add a linfeed in this line (rdate.c) for a better output:

  printf("Loop %d: time on host %s = %ld == %s \n",
         i, server, *lres, ctime(lres));


But indeed, that is the error. The output of my test (libtirpc without changes):

$ ./client ttil75
Loop 0: time on host ttil75 = 1514880129 == Tue Jan  2 09:02:09 2018
can't establish connection with host ttil75


And the test, if i patch the libtirpc (port = 0 before bind()):

$ ./client ttil75
Loop 0: time on host ttil75 = 1514879460 == Tue Jan  2 08:51:00 2018
Loop 1: time on host ttil75 = 1514879461 == Tue Jan  2 08:51:01 2018
Loop 2: time on host ttil75 = 1514879462 == Tue Jan  2 08:51:02 2018
Loop 3: time on host ttil75 = 1514879463 == Tue Jan  2 08:51:03 2018
Loop 4: time on host ttil75 = 1514879464 == Tue Jan  2 08:51:04 2018
Loop 5: time on host ttil75 = 1514879465 == Tue Jan  2 08:51:05 2018
Loop 6: time on host ttil75 = 1514879466 == Tue Jan  2 08:51:06 2018
Loop 7: time on host ttil75 = 1514879467 == Tue Jan  2 08:51:07 2018
Loop 8: time on host ttil75 = 1514879468 == Tue Jan  2 08:51:08 2018
Loop 9: time on host ttil75 = 1514879469 == Tue Jan  2 08:51:09 2018
Loop 10: time on host ttil75 = 1514879470 == Tue Jan  2 08:51:10 2018
Loop 11: time on host ttil75 = 1514879471 == Tue Jan  2 08:51:11 2018
Loop 12: time on host ttil75 = 1514879472 == Tue Jan  2 08:51:12 2018
Loop 13: time on host ttil75 = 1514879473 == Tue Jan  2 08:51:13 2018
..
..
..
Loop 96: time on host ttil75 = 1514879556 == Tue Jan  2 08:52:36 2018
Loop 97: time on host ttil75 = 1514879557 == Tue Jan  2 08:52:37 2018
Loop 98: time on host ttil75 = 1514879558 == Tue Jan  2 08:52:38 2018
Loop 99: time on host ttil75 = 1514879559 == Tue Jan  2 08:52:39 2018


I think, the cause for this error is a failure in the function bind(). But I don't know the sources of bind().

Greetings and a happy new year

Raimund

Betreff: Re: AW: RPC clnt_create() adress already in use

Hi Raimund,
I think I've now got a working RPC test-bed on my Cygwin machine.  I did have to deal with Windows Firewall but it was easy.  I installed rpcbind, started it up, compiled following your recipe and ran './server' and './client localhost' in two separate windows.  What I see is this...

./client localhost
Loop 0: time on host localhost = 1514712920 == Sun Dec 31 01:35:20 2017 can't establish connection with host localhost

Am I correct that what you expect to see is multiple lines each starting with a different "Loop" number?  And that if I use a vanilla (non-Cygwin) libtirpc I should see those multiple lines?
Thanks,

..mark
