scenario:
*************
* case one: *
*************
home via nfs and amd from solaris nfs server:
/a/sunbode2/export/home/staff/tilk
trying to make a fifo on linux host:
15:35:10].atbode63.tilk% mkfifo fifo
[15:35:38].atbode63.tilk% ls -l fifo
-rw-r--r-- 1 tilk kmem 0 Apr 22 15:35 fifo
[15:35:41].atbode63.tilk% file fifo
fifo: empty
*************
* case two: *
*************
making fifo on solaris host:
[15:33:46].sunbode2.tilk% rm fifo
[15:36:49].sunbode2.tilk% mkdir fifo
[15:36:55].sunbode2.tilk% ls -l fifo
total 0
[15:37:01].sunbode2.tilk% file fifo
fifo: directory
and let's see what's this on linux:
[15:35:47].atbode63.tilk% file fifo
fifo: character special (255/255)
[15:57:33].atbode63.tilk% ls -l fifo
crw-r--r-- 1 tilk kmem 255, 255 Apr 22 15:45 fifo
OOPS !!!!!
***************
* case three: *
***************
this time nfs server _and_ client running under linux:
15:57:37].atbode63.tilk% cd /usr/local/sci
[16:03:01].atbode63.sci% ls -l
total 0
lrwxrwxrwx 1 tilk sysadm 28 Mar 31 13:35 atbode63 ->

16:03:09].atbode63.sci% cd atbode66
[16:03:28].atbode63.atbode66% ls
[16:03:29].atbode63.atbode66% ls -la
total 2
drwxrwxrwt 2 root root 1024 Mar 31 13:40 ./
dr-xr-xr-x 3 root root 1024 Mar 31 13:39 ../
[16:03:52].atbode63.atbode66% ls -l /.stage/atbode66_sci
lrwxrwxrwx 1 root root 22 Apr 22 16:03
/.stage/atbode66_sci -> /a/atbode66/export/sci/
atbode66:/export/sci on /a/atbode66/export/sci type nfs
(rw,nosuid,intr,soft,timeo=10,retrans=8)
[16:04:10].atbode63.atbode66% mkfifo fifo
[16:04:31].atbode63.atbode66% ls -l fifo
prw-r--r-- 1 tilk kmem 0 Apr 22 16:04 fifo|
here it works !!!!
btw.:
we have here a heterogenous net with a lot of host running
aix/irix/sunos/solaris/hpux
and under all these commercial unices the scenario:
host_a: nfs server (os a)
host_b: nfs client (os b)
and making fifo on host_b in directory from host_a everything works
flawlessly
