Today, I want to introduce you to how the gssftp service that comes with Linux system is used. The content of the article Xiaobian think good, now to share with you, think there is a need for friends can understand, hope to help everyone, the following with the idea of Xiaobian to read together.

RedHat and CentOS both come with a gssftp service that can be used as follows:

[root@linux local]# cd /etc/xinetd.d[root@linux xinetd.d]# lschargen cups-lpd daytime-udp echo-udp gssftp krb5-telnet rsync time-udpchargen-udp daytime echo eklogin klogin kshell time

Edit the gssftp file by changing server_args to-l and disable to no:

[root@linux xinetd.d]# vi gssftp# default: off# description: The kerberized FTP server accepts FTP connections /# that can be authenticated with Kerberos 5.service ftp{flags = REUSEsocket_type = streamwait = nouser = rootserver = /usr/kerberos/sbin/ftpd#server_args = -l -aserver_args = -llog_on_failure += USERID#disable = yesdisable = no}

Restart xinetd service:

[root@linux xinetd.d]# service xinetd restartStopping xinetd: [ OK ]Starting xinetd: [ OK ]

Port 21 is open:

[root@linux xinetd.d]# netstat -tnlpActive Internet connections (only servers)Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program nametcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN 22543/xinetd

If the firewall does not open port, open port 21 and restart the firewall service:

[root@linux xinetd.d]# vi /etc/sysconfig/iptables[root@linux xinetd.d]# service iptables restartFlushing firewall rules: [ OK ]Setting chains to policy ACCEPT: filter [ OK ]Unloading iptables modules: [ OK ]Applying iptables firewall rules: [ OK ]

This FTP service is available, you can use linux system user login, but gssftp is not safe enough, temporary emergency or internal use can be, stable FTP service or recommended to use vsftp to build.

Linux is a free-to-use and freely distributed UNIX-like operating system, is a POSIX-based multi-user, multitasking, multi-threaded and multi-CPU operating system, using Linux to run major Unix tools, applications and network protocols.

The above is the Linux system comes with the gssftp service is how to use the full content of the, more and Linux system comes with the gssftp service is how to use the related content can be searched before the article or browse the following article to learn Ha! I believe that Xiaobian will add more knowledge to everyone, I hope you can support it!
