SCO NFS client with HP/Apollo NFS server?

SCO NFS client with HP/Apollo NFS server?

Post by Mark Eva » Sun, 09 Jan 1994 01:44:28



I am trying to NFS mount a remote HP/Apollo file system on a SCO
Opendesktop platform with limited success.  A couple of things are
*ed up:

    SCO NFS has trouble with Apollo soft links pointing to a file
    pathname of the form //node/path/filename.  For some reason SCO
    truncates the last two characters of the filename.  Directory
    links, on the other hand, are handled properly.  NOTE:  I have
    other NFS clients (SGI, Tandem) which do not exhibit this problem.

    I can maybe work around the above problem by changing my
    soft links.  A more basic problem, however, is that remote
    file access is flaky.  I can read small (< 4KB) files, but
    larger files cause it to hang.  Perhaps I need to diddle
    with NFS mount parameters.  It is currently running with
    defaults.

Any suggestions would be greatly appreciated.  Has anyone gotten
a SCO NFS client to talk to an Apollo NFS server?  Is SCO NFS
industrial strength?

Many thanks

The two environments are as follows.

SCO:

SCO ODT 3.0.0
Release = 3.2v4.2
Machine = i80386
BusType = ISA

Apollo:

Domain OS, 10.3.5, NFS V2.3

In case this isn't clear, on the Apollo, I say:

     cd //blast/user/mse/tmp
     ln -s //blast/user/mse/blah blah

On SCO,

     cd /hp/blast/user/mse/tmp   # where /hp/blast is the mount point for //blast
     ls -l blah

[...] 21 Jan 07 13:51 blah -> /hp/blast/user/mse/bl

Note that the Apollo is configured to translate //blast to /hp/blast
which the SCO NFS client picks up on.

In case anyone else is stumped, I have solved the second problem by
adding the following options to the mount command (applicable to
3COM503 card):

    rsize=4096,wsize=4096,soft,intr

The first problem is still open.  Suggestions will be appreciated.

1. NFS server on HP-UX 10.20 & NFS client on RH-5.2 : write permission ???

Hi,
I have a HP-UX 10.20 workstation (named ltas18) and a Linux RH-5.2 box
(named bobo).
I would like to setup NSF with server=HP-UX and client=RH-5.2.

This is my /etc/exports on HP-UX:

/home/dang/quy -anon=65534,root=bobo:ltas22,access=bobo:ltas22
/disk4/dang/quy -anon=65534,root=bobo:ltas22,access=bobo:ltas22

On my Linux "bobo", in the /etc/fstab file I have :

/dev/hda5 / ext2    defaults  1 1
/dev/hda1  /mnt/dos vfat   noauto,user,rw  0 0
/dev/hda6   swap swap    defaults  0 0
/dev/fd0  /mnt/floppy  vfat    user,noexec,nodev,nosuid,rw,noauto 0 0
/dev/cdrom  /mnt/cdrom  iso9660 user,noexec,nodev,nosuid,ro,noauto 0 0
/dev/sda4  /mnt/zip vfat    user,noexec,nodev,nosuid,rw,noauto 0 0
ltas18:/home/dang/quy /mnt/ltas18 nfs user,rw,auto,rsize=8192,wsize=8192
0 0
ltas18:/disk4/dang/quy /mnt/disk4-ltas18 nfs
user,rw,auto,rsize=8192,wsize=8192 0 0

From my account on "bobo" I tried:

$ mount /mnt/ltas18

It works ! But I have not write permission on this ! Howto to acces to
NFS with "rw" permission ? I have already defined "rw" in potion of
fstab !

However, with root on "bobo" I can write into /mnt/ltas18 but with owner
and group ID of my Linux box, not exist in HP-UX machine !!

Howto to define ID of user and ID of group on the remote (server) &
local (client) ????

Thank you very much and it's possible I would like to receive your
message at my e-mail address.

Thanks !
