how to backup files from solaris 8 to linux rh 6.0 or vice-versa across home
networking at 11:30 pm???
thanks!

Setup the machines so they love each other (.rhosts stuff).
From Solaris try something like ufsdump -0cuf
<remote_host>:/dev/<tape_device> <filesystem_to_dump>
Example: ufsdump -0cuf mars:/dev/st0 /
I would script it for multiple partitions.
Works for Solaris to Solaris.

ufsdump (Solaris) or dump (Linux) to standard output, then pipe that
through ssh to the other computer to dd to the tape device.  Of course,
one of the computers must trust the other in some manner that ssh
supports.  It can also be done with rsh, though only the .rhosts method
of trust is supported.

I have .rhost of the opposite hostname in the directory , I still have
permission deny stmt.

Can you rsh or rlogin to the other host without needing to type in
the password?  After logging in, find out what host the host you
just logged into thinks you are coming from (via last, finger, etc.).
If name resolution is incorrectly set up, you may have to use the
IP address.  In some other situations, there may be several host names,
only one of which will match.

Also check the permissions on the $HOME/.rhosts file.

And check into using ssh, which gives more security as well as more
options for authentication methods.

Beware of incompatibilities......

This will only work if your software does not use more functionality
than:

-       open() with open mode from O_RDONLY, O_WRONLY, O_RDWR

-       read()/write()

-       seek()

If you like to do more, you should switch to the 'rmt' Implementation
from star (ftp://ftp.fokus.gmd.de/pub/unix/star/alpha/)

This rmt server gives 100 % compatibility to:

-       old 1981 BSD features

-       Sun/Solaris extensions that give compatibility for MTIO opcodes > 7
        and allow to use MTIOCGET status call.

-       GNU extensions that allow to use more than the two lowest
        bits in the open() modes.

-       Schily SING extensions that deal with Linux ioctl incompatibility
        for MTIO op codes in the range 0..7

In addition, it gives you up to 40% more speed compared to a Sun rmt server
and it implements additional security features.

As it may be installed as "login shell", you don't need overwrite your
system's /etc/rmt in order to use it.

*************************************************************************
NEVER NEVER use the GNU 'mt' command (as found on Linux) in remote mode
if only one of the machines runs Linux!
*************************************************************************

If you call (from Linux)

The solaris host will perform a RETENSION. Worse things may happen
with other commands.

The mt command that comes with star does not have this problem if you use the
rmt server that comes with star.

Depending on how complex your setup is you might want to take a look at
Arkeia ( http://www.knox-software.com )

The easiest way might be to NFS mount the solaris filesystems onto the
RedHat box and run your backup from there as you would for local
filesystems.
