netstat -l | grep telnet

Problem in connecting to the ftp server

I had a Linux system and I tried to ftp to the server. I was getting the following error:

Connected to site.com.
220 ns1.site.com FTP server (Version 5.60) ready.
User (site.com:(none)): user
530 Must perform authentication before identifying USER.
Login failed.
ftp> bye
221 Goodbye.

To resolve the problem I updated the entry in the /etc/xinit.d/gssftp file. I located the entry server_args = -l -a  and removed -a option. Then I issued the following command.

service xinetd restart

This solved the problem.

 

ftp不能对root帐户操作的原因有2个 
1. /etc/ftpusers里面有root, 
2. 还有一个原因就是/sbin/sh缺省情况下/etc/shells里面是注释掉的 
所以你要对root进行ftp, 在unixware下还要修改/etc/shells把/sbin/sh前的#号去掉

 

redhat 7.x不能用root用户ftp，telnet

用root 登陆 在/etc/pam.d/login里把第一行注释上就行了。

现想用telnet远程登录这台机器,root用户不能登录
打开/etc/xinetd.d/krb5-telnet 然后把disable=yes 改成no
再打开/etc/pam.d/login 里pam_securerrytty.so注释
重启xinetd　

service   xinetd   restart   启动telnet服务

 

netstat -l | grep telnet

tcp        0      0 *:telent          *:*       LIST　　telnet服务正常

netstat -l | grep ftpserver
