This seems to come close to what you're expecting (without needing GNU awk >= 4):
Code:
awk '
/^\// { $3 = 13
        $4 = "*"
        $5 = "$W1"
        printf("%s", $1)
        for(w = length($1); w < 40; w += 8) printf("\t")
        printf("%-5d%-2d\t   %s\t%-6s%s\n", $2, $3, $4, $5, $6)
        next
}
1' input

If you're using a Solaris/SunOS system, use /usr/xpg4/bin/awk or nawk instead of awk.
It produces:
Code:
... ... ...
# contents of maillog, messages, and lpd-errs to be confidential.  In the
# future, these defaults may change to more conservative ones.
#
# logfilename          [owner:group]    mode count size when  flags [/pid_file] [sig_num]
/var/log/appfirewall.log		640  13	   *	$W1   J
/var/log/ftp.log			640  13	   *	$W1   J
/var/log/hwmond.log			640  13	   *	$W1   J
/var/log/install.log			640  13	   *	$W1   J
/var/log/ipfw.log			640  13	   *	$W1   J
/var/log/lookupd.log			640  13	   *	$W1   J
/var/log/lpr.log			640  13	   *	$W1   J
/var/log/mail.log			640  13	   *	$W1   J
/var/log/ppp.log			640  13	   *	$W1   J
/var/log/secure.log			640  13	   *	$W1   J
/var/log/system.log			640  13	   *	$W1   J
/var/log/wtmp				644  13	   *	$W1   B

except that the copy and paste used to produce this converts the tabs in the output to spaces.

startsrv

STARTSRV(8)						      System Manager's Manual						       STARTSRV(8)

NAME

       startsrv - invoke ttysrv for a particular host.

SYNOPSIS

       startsrv host

DESCRIPTION

       startsrv  fires	up  ttysrv  for  a  given  host.  It  will  kill  any  already	running  instance  for	that  host, then read /etc/remote-
       tty/opt/<host>.srv for any options to pass to ttysrv (defaulting to those that set 9600,8n1), /etc/remote-tty/prot/<host>.sock for the per-
       missions the socket should be set to (default 660), /etc/remote-tty/owner/<host>.sock for the owner of the socket (default rttymgr:dialout)
       and /etc/remote-tty/prot/<host>.log for the permissions of the logfile (default 640).

       The device node used is /etc/remote-tty/dev/<host>. This will normally be a symlink to the correct file in /dev.

       ttysrv is configured to log to /var/log/remote-tty/<host>/<host>, with a  pidfile  at  /var/run/remote-tty/pid/<host>  and  the	socket	at
       /var/run/remote-tty/sock/<host>.

SEE ALSO

       remote-tty(1), ttysrv(8).
