ubuntu12.4下tftp设置精华
因调试6410开发板,需在ubuntu12.04下搭建tftp服务器,在网搜了多个ubuntu下配置tftp的文件,发现都有或多或少的问题,如下是我的配置过程,已验证通过可供参考!!!
1)安装tftp-hpa,tftpd-hpa, xinetd
~$ sudo apt-get install tftp-hpa , tftpd-hpa, xinetd
2) 在/etc/xinetd.d/下创建并配置tftp文件
~$ sudo vim /etc/xinetd.d/tftp
1 service tftp
2 {
3 socket_type = dgram
4 protocol = udp
5 wait = yes
6 user = root
7 server = /usr/sbin/in.tftpd
8 server_args = -s/tftpboot -c
9 disable = no
10 per_source = 11
11 cps =100 2
12 flags = IPv4
13 }
-c 用于开启上传功能。
3)配置tftpd-hpa
~$ sudo vim /etc/default/tftpd-hpa
1 #/etc/default/tftpd-hpa
2
3 TFTP_USERNAME="tftp"
4 TFTP_DIRECTORY="/tftpboot"
5 TFTP_ADDRESS="0.0.0.0:69"
6 TFTP_OPTIONS="-l -c -s"
其中/tftpboot为 tftp共享目录
4) 修改xinetd.conf文件
~$ sudo vim /etc/xinetd.conf
defaults
6 {
7
8 # Please note that you need a log_type line to be able to use log_on_success
9 # and log_on_failure. The default is the following :
10 # log_type = SYSLOG daemon info
11
12 }
13
14 #includedir /etc/xinetd.d
15 tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftpboot
5) 重启tftp服务并测试
sudo service tftpd-hpa restart
sudo /etc/init.d/xinetd reload
sudo /etc/init.d/xinetd restart
6)本机测试
在/tftpboot下创建测试文件love
#cd /tftpboot
#echo xuguodongaigongxia > love
#chmod 777 love
测试一下 tftp服务:
重新打开一个终端
#tftp 127.0.0.1
tftp>get love
tftp>q
#ls
退出后,查看当前目录,发现love文件已在当前目录。
如果上述设置还不行的话,那么就要把selinux禁用掉:
sudo gedit /etc/selinux/config //如果没有selinux/config这个文件,则创建。
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
把上面的SELINUX=enforcing 改为:SELINUX=disable 禁用SeLinux
然后reboot重启PC
