Hi All,
I want to disable bunch of unused services on SLES and RHEL to improve the performance. Since we have more than 100 servers to disable services, I want to do with some script. Any one can give me an idea how to write a script to disable services. Thanks

I had a doubt if any services need to be restarted if port no in /etc/services in an RHEL setup is changed. For eg, the port no of 443 for SSL may need to be changed.
I hope my query is clear whether any services need to be restarted if port no in /etc/services is changed.

services_mkdb
SERVICES_MKDB(8) BSD System Manager's Manual SERVICES_MKDB(8)
NAME
services_mkdb -- generate the services database
SYNOPSIS
services_mkdb [-b | -l] [-q] [-o database] [file]
services_mkdb -u [file]
DESCRIPTION
The services_mkdb utility creates a db(3) database for the specified file. If no file is specified, then /etc/services is used. The data-
base is installed into /var/db/services.db. The file must be in the correct format (see services(5)).
The options are as follows:
-b Use big-endian byte order for database metadata.
-l Use little-endian byte order for database metadata.
-o database
Put the output databases in the named file.
-q Do not warn about duplicate services.
-u Print the services file to stdout, omitting duplicate entries and comments.
The databases are used by the C library services routines (see
The -b and -l flags are mutually exclusive. The default byte ordering is the current host order. getservent(3)).
FILES
/var/db/services.db The current services database.
/var/db/services.db.tmp A temporary file.
/etc/services The current services file.
EXIT STATUS
The services_mkdb utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
db(3), getservent(3), services(5)
BUGS
Because services_mkdb guarantees not to install a partial destination file it must build a temporary file in the same file system and if suc-
cessful use rename(2) to install over the destination file.
If services_mkdb fails it will leave the previous version of the destination file intact.
