Hi,

I have a FreeBSD server which exports a filesystem which contains a
named pipe.
When i try to access the pipe from my linux box, it sees a character
device instead.

----------------------------------------------------
View from FreeBSD Server (FreeBSD 3.3-RELEASE):

root@pcsrv1 [/data/kits/diskimages]# ls -l x
prw-rw-r-- 1 rebehn wheel 0 Feb 6 12:24 x

-----------------------------------------------------
View from linux box (Linux reno 2.2.13 #8 SMP):

reno:~# mount pcsrv1:/data/kits/ /mnt
reno:~# cd /mnt/diskimages
reno:/mnt/diskimages# ls -l x
crw-rw-r-- 1 rebehn root 255, 255 Feb 6 13:24 x
^ ^^^ ^^^
--------------------------------------------------------------------------------
View from Solaris box (SunOS paris 5.7 Generic sun4m sparc
SUNW,SPARCstation-20):

root@paris [/home/admin/backup]# mount pcsrv1:/data/kits /mnt
root@paris [/home/admin/backup]# cd /mnt/diskimages/
root@paris [/mnt/diskimages]# ls -l x
prw-rw-r-- 1 rebehn root 0 Feb 6 13:24 x

The same happens with a solaris nfs-export. FreeBSD sees the pipe ok,
linux sees a character device.

Is this a known issue?

Any help would be appreciated.
