SOLARIS有关ftp/telnet的配置文件-红联Linux系统门户

系统安装好了，默认情况下除root用户外的其他用户ftp/telnet是可用的，如果需要对ftp/telnet做一些调整，需要修改配置文件，ftp/telnet涉及到的文件有下面一些。

ftp stream tcp6 nowait root /usr/sbin/in.ftpd in.ftpd
telnet stream tcp6 nowait root /usr/sbin/in.telnetd in.telnetd

# Syntax for TLI-based Internet services:

#
# By specifying a value of tcp6 or udp6 for a service, inetd will
# pass the given daemon an AF_INET6 socket. The following daemons have
# been modified to be able to accept AF_INET6 sockets
#
# ftp telnet shell login exec tftp finger printer
#
# and service connection requests coming from either IPv4 or IPv6-based
# transports. Such modified services do not normally require separate
# configuration lines for tcp or udp. For documentation on how to do this
# for other services, see the Solaris System Administration Guide.
#
# You must verify that a service supports IPv6 before specifying as
# tcp6 or udp6. Also, all inetd built-in commands (time, echo, discard,
# daytime, chargen) require the specification of as tcp6 or udp6
#
# The remote shell server (shell) and the remote execution server
# (exec) must have an entry for both the "tcp" and "tcp6" values.
#
# Ftp and telnet are standard Internet services.

# RPC services syntax:
# /

rpc/ \
#
#
# can be either "tli" or "stream" or "dgram".
# For "stream" and "dgram" assume that the endpoint is a socket descriptor.
# can be either a nettype or a netid or a "*". The value is
# first treated as a nettype. If it is not a valid nettype then it is
# treated as a netid. The "*" is a short-hand way of saying all the
# transports supported by this system, ie. it equates to the "visible"
# nettype. The syntax for is:
# *||{[,]}
# For example:
# dummy/1 tli rpc/circuit_v,udp wait root /tmp/test_svc test_svc

第二，root用户的ftp/telnet，默认情况下root用户是不允许ftp/telnet的，修改/etc/ftpusers配置文件，将root用户注释掉，则root用户才可以ftp，如果想让某个用户不能ftp，可以将其加到这个文件中来。
ftpusers文件内容如下
#root
daemon
bin
sys
adm
lp
uucp
nuucp
listen
nobody
noaccess
nobody4

修改/etc/default/login配置文件，找到CONSOLE=/dev/console，将其注释掉，就可以用root用户telnet了。

附：/etc/default/login配置文件

# ident "@(#)login.dfl 1.13 03/01/10 SMI"
#
# Copyright 1989-2002 Sun Microsystems, Inc. All rights reserved.
# Use is subject to license terms.
#
# Set the TZ environment variable of the shell.
#
#TIMEZONE=EST5EDT
# ULIMIT sets the file size limit for the login. Units are disk blocks.
# The default of zero means no limit.
#
#ULIMIT=0
# If CONSOLE is set, root can only login on that device.
# Comment this line out to allow remote login by root.
#
# CONSOLE=/dev/console
# PASSREQ determines if login requires a password.
#
PASSREQ=YES
# ALTSHELL determines if the SHELL environment variable should be set
#
ALTSHELL=YES
# PATH sets the initial shell PATH variable
#
#PATH=/usr/bin:
# SUPATH sets the initial shell PATH variable for root
#
#SUPATH=/usr/sbin:/usr/bin
# TIMEOUT sets the number of seconds (between 0 and 900) to wait before
# abandoning a login session.
#
#TIMEOUT=300
# UMASK sets the initial shell file creation mode mask. See umask(1).
#
#UMASK=022
# SYSLOG determines whether the syslog(3) LOG_AUTH facility should be used
# to log all root logins at level LOG_NOTICE and multiple failed login
# attempts at LOG_CRIT.
#
SYSLOG=YES
# SLEEPTIME controls the number of seconds that the command should
# wait before printing the "login incorrect" message when a
# bad password is provided. The range is limited from
# 0 to 5 seconds.
#
#SLEEPTIME=4
# DISABLETIME If present, and greater than zero, the number of seconds
# login will wait after RETRIES failed attempts or the PAM framework returns
# PAM_ABORT. Default is 20. Minimum is 0. No maximum is imposed.
#
#DISABLETIME=20
# RETRIES determines the number of failed logins that will be
# allowed before login exits.
#
#RETRIES=5
#
# The SYSLOG_FAILED_LOGINS variable is used to determine how many failed
# login attempts will be allowed by the system before a failed login
# message is logged, using the syslog(3) LOG_NOTICE facility. For example,
# if the variable is set to 0, login will log -all- failed login attempts.
#
#SYSLOG_FAILED_LOGINS=5
第三，如果想让某个用户只能ftp，不能telnet。可以先把/etc/passwd文件中该用户的shell改成/usr/sbin/nologin，然后再在/etc目录下建一个shells文件，里面加入/usr/sbin/nologin。
