32 Getting ready to install VCS One
Configuring ssh, rsh, or remsh before installing
2 Remove the “rsh” entry in the
/etc/securetty
file.
3 Disable the rsh server. Enter the following:
chkconfig rsh off
4 To ensure security, delete the .rhosts file from each user’s $HOME directory.
Enter the following:
rm -f $HOME/.rhosts
Configuring remsh on HP-UX
Remote shell (remsh) functionality is enabled automatically after installing an
HP-UX system.
Modifying the .rhosts file on HP-UX
A separate .rhosts file is in the $HOME directory of each user. You must modify
the .rhosts file for each user who remotely accesses the system using remsh.
Make sure that each line of the .rhosts file contains a fully-qualified domain
name or IP address for each remote system having access to the local system.
For example, if the root user must remotely access system1 from system2, you
must add an entry for
system2. companyname .com
in the .rhosts file on
system1.
To modify the .rhosts file on HP-UX
1 Enter the following:
echo "system2. companyname .com" >> $HOME/.rhosts
2 To ensure security, delete the
.rhosts
file from each user’s
$HOME
directory. Enter the following:
rm -f $HOME/.rhosts
For more information on configuring remsh, see the operating system
documentation and the
remsh
(1M) manual page.
Configuring rsh on AIX
To configure rsh on AIX
1 Enable rsh. Create a
/.rhosts
file on each target system. Add a line to the
file specifying the full domain name of the source system. For example, add
the following line:
sysname. domainname .com root
2 Change permissions on the
/.rhosts
file to 600. Enter the following:
chmod 600 /.rhosts
