Dear Guru's
I'm using Putty and want to edit a file. I know we generally use vi editor to do it. As I'm not good in using vi editor, I want to convert the vi into something like text pad. Is there any option in Putty to do the same ? Thanks for your response.

rplay.hosts
RPLAY.HOSTS(5) File Formats Manual RPLAY.HOSTS(5)
NAME
rplay.hosts - rplay host authentication database
SYNOPSIS
/usr/local/etc/rplay.hosts
DESCRIPTION
The rplay.hosts file contains a list of hosts and access permissions which rplayd uses to validate incoming connections. Each line is of
the form:
hostname[:permission]
where
hostname is the name of a remote host or a host's IP address. Wildcards can be used within IP addresses to match multiple hosts.
The wildcard character is "*".
permission is an optional field containing any combination of the following characters:
r the host can read sounds.
w the host can write sounds.
x the host can play, stop, pause, and continue sounds. This is normally called execute permission.
m the host can monitor the audio stream written by rplayd to the audio device.
"rx" permissions are used when no permissions are specified.
EXAMPLE
#
# All hosts have read access:
#
*:r
#
# Trusted hosts:
#
nice-guy.sdsu.edu:rwx
friend.sdsu.edu:rwx
amigo.sdsu.edu:rwx
130.191.224.224:rwx
#
# Hosts which can read and execute:
#
foo.bar.com:rx
130.190.*:rx
146.244.234.*:rx
using.default.perms.edu
#
# Hosts which can monitor the audio stream
#
nsa.sdsu.edu:m
FILES
/usr/local/etc/rplay.hosts
SEE ALSO
rplayd(1)
BUGS
The permissions for an "*" entry apply to all matching hosts. The order of this file does not matter. Specific hosts can have access dis-
abled with entries like:
bad.guy.edu:
however, any matching "*" entries will still apply.
