尚观第十一天学习笔记ssh ftp
NFS：nfs提供文件系统
portmap 提供协议rpc
# /etc/init.d/portmap restart
# /etc/init.d/nfs restart
配置文件：
主包：nfs-utils
# vim /etc/exports
/tmp *(rw,no_root_squash)
# mount -t nfs 192.168.100.253:/tmp/mnt/nfs/
# showmount -e 192.168.100.253
Export list for 192.168.100.253:
/tmp *
# showmount -a 192.168.100.253
ssh：
# /etc/init.d/sshd start
启动 sshd： [确定]
ssh无密码登录：
# ssh-keygen
# scp id_rsa.pub 192.168.100.3:/root/.ssh/authorized_keys
修改端口：
# vim /etc/ssh/sshd_config
tcp wrapper:
vim /etc/hosts.allow
vim /etc/hosts.deny
sshd:192.168.100.155
sshd:192.168.100.
sshd:192.168.100.0/255.255.255.0
sshd:192.168.100.0/24
sshd:192.168.100.*
sshd:192.168.100.1?,192.168.100.2?
samba:
配置文件：
# vim /etc/samba/smb.conf
74 workgroup = MYGROUP ／／工作组
75 server string = Samba Server／／描述
security = share／／共享级别
289
290 comment = this is mysamba!
291 path = /haha
292 public = yes
293 writable = yes
重启服务：
# /etc/init.d/smb restart
客户端挂载：
# mount -t cifs //192.168.1.253/mysamba /mnt/samba
Password:
# cd /mnt/samba
# ls
a b
user级别（带用户名和密码）：
vim /etc/samba/smb.conf
security = user
comment = this is mysamba!
path = /heihei
writable = yes
添加本地帐户：
# useradd smbuser1
添加smb帐户：
# smbpasswd -a smbuser1
New SMB password:
Retype new SMB password:
Added user smbuser1.
挂载（user级别）：
# mount -t cifs -o username=smbuser1 //192.168.1.253/mysamba /mnt/samba1
Password:
# smbclient -L 192.168.1.253

常用共享属性：
comment = this is mysamba!
path = /heihei
public = yes
writable = yes
write list = user1 user2 @grp1 @grp2
read only = yes
read list = user1 user2 @grp1 @grp2
browseable = yes
valid users = user1 user2 @grp1 @grp2
printable = no
tftp:基于xinetd的服务
# /etc/init.d/xinetd restart
# vim /etc/xinetd.d/tftp
disable = no
server_args = -s -c /tftpboot
