tried to transfer the dosread-command with dd?
something like
dd </usr/bin/dosread >/dev/your_diskdrive
and vice versa on the target system

Subject: restoring permission's on root file system .
We are following process to restore permission's on root file
system . Now we have reset.perms.out file on another aix system .
We are trying to copy this file to bad aix system so that we can
execute and restore permission's .unfortunately there is no
doswrite/read commands on target system. since system is booted in
maintenance mode cannot install bos.dosutil file set .
we are trying dd, cpio etc..
Is there a way to copy file from one aix system to another aix
system ? using any other commands than dosread and doswrite ?
or can we bring network up in maintenance mode ? so that we can
ftp this file .
drwxr-xr-x 2 root system 1024 Dec 30 08:49 drinfo
-rw-r--r-- 1 root system 733137 Jan 09 12:34
reset.perms.out.Z (want to copy this file )
drwxr-xr-x 2 root system 512 Jan 09 13:23 reset
spcws01@/tmp>
Thanks

Check this out-
it uses a mksysb tape of the damaged system to generate a script
to fix
perms-

if you don't have a mksysb tape, you can use the following:
You run the script listed below on A GOOD system with correct
permissions. This will generate a file 'reset.perms.out' which
contains the necessary 'chmod' and 'chown' commands to restore
permissions on the affected system. You can then COPY this file
over to the BAD system and run it.
-- begin script --
#!/bin/ksh
cd /tmp
rm reset.perms.out 2>/dev/null
find / -ls |awk '{print $3,$4,$5,$6,$7,$8,$9,$10,$11,$12}'|
awk '{
if ( NF == "9" )
{
printf ("chown %s.%s %s\n",$3,$4,$9)
{
perms=0
if(substr($1,2,1) == "r")
perms = perms + 400
if(substr($1,3,1) == "w")
perms = perms + 200
if(substr($1,4,1) == "x")
perms = perms + 100
if(substr($1,4,1) == "S")
perms = perms + 4000
if(substr($1,4,1) == "s")
perms = perms + 4100
if(substr($1,5,1) == "r")
perms = perms + 40
if(substr($1,6,1) == "w")
perms = perms + 20
if(substr($1,7,1) == "x")
perms = perms + 10
if(substr($1,7,1) == "S")
perms = perms + 2000
if(substr($1,7,1) == "s")
perms = perms + 2010
if(substr($1,8,1) == "r")
perms = perms + 4
if(substr($1,9,1) == "w")
perms = perms + 2
if(substr($1,10,1) == "x")
perms = perms + 1
if(substr($1,10,1) == "T")
perms = perms + 1000
if(substr($1,10,1) == "t")
perms = perms + 1001
printf("chmod %d %s # %s\n",perms,$9,$1)
}
}
}' >reset.perms.out
chmod 755 reset.perms.out

Subject: permission's or / (root) changed
Hi all,
Our Junior-while working with Developer changed some permission
on root file
system, I don't have details but he was telling me developer
provided some
script to change permission's and he accidentally executed on
root file
system.
Now we are getting messages processes spawning to rapidly ...
the box is
down. I started working with him to restore this box.
What are our options?
I know I can restore from mksysb. (He is in doubt about mksysb
tape -
created one year ago :-) and searching one .
Assuming that we don't get mksysb -
Can I install AIX from CD and do importvg on whatever volume
groups were
there?
Or is there any way to set / permission's to original one?
Thank You
SD
