redhat linux下配置rsh和rcp
1首先確認機器是否安裝rsh包:
[oracle@linux ~]$ rpm -aq |grep rsh
rsh-0.17-25.4
rsh-server-0.17-25.4
如果沒有安裝以上兩個包，請找到相關軟件安裝(如果是LINUX，可以從安裝碟中找到)
安裝包:
rpm -ivh rsh-0.17-5 (linux 操作系統)
rpm -ivh rsh-server-0.17-5 (linux 操作系統)
2: 修改/etc/xinetd.d/rsh腳本文件
no
[root@linux ~]# vi /etc/xinetd.d/rsh
rsh 屬於xinetd服務，修改/etc/xinetd.d/rsh腳本文件文件中的選項
將disable 設置為no
# default: on
# description: The rshd server is the server for the rcmd(3) routine and, /
# consequently, for the rsh(1) program. The server provides /
# remote execution facilities with authentication based on /
# privileged port numbers from trusted hosts.
service shell
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rshd
# disable = yes
disable = no
}
3．重啟rsh服務
[root@linux ~]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
4. 檢查是否啟動: rsh server 監聽和TCP 是514。
[root@linux ~]# netstat -an |grep 514
tcp 0 0 0.0.0.0:514 0.0.0.0:* LISTEN
unix 3 [ ] STREAM CONNECTED 44514
5：配置rsh server
修改/etc/securetty文件: echo rsh >>/etc/securetty
如果打算用root作為rsh用戶的話:
先用root登錄到機器A中進行以下操作:
[root@linux ~]# echo "192.168.7.10 root" >>.rhosts //允許192.168.0.10 以root訪問
[root@linux ~]# echo "192.168.7.15 root" >>.rhosts
重啟rsh server.
.rhosts一般位於 rsh server服務器相對應賬號目錄下比如root(與.bash_profile在同一目錄)
查看是否配置成功：
[root@linux ~]# more .rhosts
192.168.7.10 root
192.168.7.15 root
6：配置vi /etc/hosts，加入對方的IP和機器名(hostname)。機器名可以參考127.0.0.1一行。
[root@linux ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 linux localhost.localdomain localhost
192.168.7.15 linux ＃本機ip及機器名
192.168.7.10 hlht ＃遠程服務器ip及機器名
7：配置vi /etc/hosts.equiv
[root@linux ~]# vi /etc/hosts.equiv
127.0.0.1 localhost
192.168.7.10 hlht
192.168.7.15 linux
8：到/etc/pam.d/目錄下，把rsh文件中的auth required pam_securetty.so一行用“#”封掉即可(注意修改紅色字體一行：加＃)
[root@hlht ~]# cd /etc/pam.d
[root@hlht pam.d]# vi rsh
#%PAM-1.0
# For root login to succeed here with pam_securetty, "rsh" must be
# listed in /etc/securetty.
auth required pam_nologin.so
#auth required pam_securetty.so
auth required pam_env.so
auth required pam_rhosts_auth.so
account required pam_stack.so service=system-auth
session required pam_stack.so service=system-auth
9：重啟rsh server.
[root@linux ~]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
10:測試和注意的問題:
登錄到192.168.7.10機器進行測試
看是否能看到結果。如果看到
[oracle@linux ~]$ rsh -l oracle 192.168.7.10 ps -ef
connect to address 192.168.7.10: Connection refused
Trying krb4 rsh...
connect to address 192.168.7.10: Connection refused
trying normal rsh (/usr/bin/rsh)
Permission denied.
這是由於權權限問題，一般是由於 .rhosts沒有配置正確。.rhosts一般位於
rsh server服務器相對應賬號目錄下比如root(與.bash_profile在同一目錄)
如果看到
[root@linux pam.d]# rsh -l root 192.168.7.10 env|grep PATH
connect to address 192.168.7.10: Connection refused
Trying krb4 rsh...
connect to address 192.168.7.10: Connection refused
trying normal rsh (/usr/bin/rsh)
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/bin:/bin
表示rsh配置成功，可以使用rcp進行遠程拷貝。
11.RCP 遠程目錄拷貝
[root@hlht run]# rcp -r source linux:/opt/oracle/yljs
//linux為剛才配置的192.168.7.15服務器名
connect to address 192.168.7.15: Connection refused
Trying krb4 rcp...
connect to address 192.168.7.15: Connection refused
trying normal rcp (/usr/bin/rcp)
[root@hlht run]#
root用戶可以操作；普通用戶好像不行；沒有配置好普通用戶的遠程拷貝。
