表 6-1. 本章重要的OpenSSH 程序和文件 |
|
|
客户端程序 |
|
|
ssh |
远程登陆和远程命令执行 |
|
scp |
拷贝文件 |
|
sftp |
交互式拷贝文件,类似FTP |
|
服务器程序 |
|
|
sshd |
服务器后台进程 |
|
创建和使用密钥的程序 |
|
|
ssh-keygen |
创建和修改公钥和私钥 |
|
ssh-agent |
缓存SSH 私钥, |
|
ssh-add |
操作 key cache of ssh-agent |
|
重要的文件和目录 |
|
|
~/.ssh |
存储密钥及其配置文件 |
|
/etc/ssh |
密钥及其配置文件的系统配置目录 |
|
~/.ssh/config |
客户端配置文件 |
|
/etc/ssh/ssh_config |
客户端配置文件(系统级) |
以上可能适用于其他的ssh,比如SSH Secure Shell (), 更多信息可参考< SSH, The Secure Shell: The Definitive Guide (O'Reilly).>
当前用户是root, 常用的登陆方式:
# ssh
# ssh
# ssh -l meil
参数如下:
usage: man [-adfhktwW] [section] [-M path] [-P pager] [-S list]
[-m system] [-p string] name ...
a : find all matching entries
c : do not use cat file
d : print gobs of debugging information
D : as for -d, but also display the pages
f : same as whatis(1)
h : print this help message
k : same as apropos(1)
K : search for a string in all pages
t : use troff to format pages for printing
w : print location of man page(s) that would be displayed
(if no name given: print directories that would be searched)
W : as for -w, but display filenames only
C file : use `file' as configuration file
M path : set search path for manual pages to `path'
P pager : use program `pager' to display pages
S list : colon separated section list
m system : search for alternate system's man pages
p string : string tells which preprocessors to run
e - [n]eqn(1) p - pic(1) t - tbl(1)
g - grap(1) r - refer(1) v - vgrind(1)

非交互式程序可以这样执行, 不会建立login会话
[root@Meil89 sda1]# ssh
root@
12:04:21 up 7 days, 13:58, 1 user, load average: 0.00, 0.00, 0.00
交互式程序可这样执行, -t使SSH 分配一个pseudo-tty, 以下如果不是用”-t” 将不能编辑, 多见于基于文本的终端和游戏.
ssh
图形相关可以这样执行: 比如打开远程的终端窗口
ssh -X -f server.example.com xterm
要确认远程端,没有设置DISPLAY, SSH会自动设置为正确的值,一般在bash_profile or .bashrc和/etc/profile(全局)可设置,也有可能使/etc/ssh/sshd_config中没有打开X11Forwarding
scp -rp ./* meil@
Scp最常用的参数为 -r递归,包含目录, -p保持原有属性
使用以下,
rsync -a -e ssh .
有如下好处,
避免scp拷贝符号连接, 以及不管文件在不在都进行拷贝.
加-v可以显示详细信息.
rsync -a -e ssh -v .
参数如下:
man, version 1.5k
usage: man [-adfhktwW] [section] [-M path] [-P pager] [-S list]
[-m system] [-p string] name ...
a : find all matching entries
c : do not use cat file
d : print gobs of debugging information
D : as for -d, but also display the pages
f : same as whatis(1)
h : print this help message
k : same as apropos(1)
K : search for a string in all pages

P pager : use program `pager' to display pages
S list : colon separated section list
m system : search for alternate system's man pages
p string : string tells which preprocessors to run
e - [n]eqn(1) p - pic(1) t - tbl(1)
g - grap(1) r - refer(1) v - vgrind(1)
