1.安装telnet 和telnet-server yum -y install telnet yum -y install telnet-server 注意：在此安装过程中，会依赖解决xinetd的超级守护进程的安 装 --仅仅是centos6 centos7 如需要xinetd则手动安装 xinetd yum -y install xinetd service xinetd restart systemctl enable xinetd.service --将xinetd 加入开机启动 systemctl start telnet.socket 再启动telnet 注意:不能登陆到 root 且登陆普通用户 需要有密码 如失败 请先关闭双方防火墙 service firewalld stop chkconfig --list --检查xinetd支持项目 CentOS7 xinetd不再支持 telnet CentOS6 使用xinetd 开放 telnet服务: # chkconfig --list | grep 'telnet' telnet: off 　　 　　 # chkconfig telnet on 　　 # chkconfig --list | grep 'telnet' telnet: on 　　注意:不能登陆到 root 且登陆普通用户 需要有密码 如失败

I am required to test at least 130 ip addresses and ports. I am hoping to write a bash script such that it reads the ip address and ports from an input file. I have the following while read line do telnet $line >> $2 done < $1 This is a crappy code as it cannot determine whether its connected or failed, and I have to rely on its auto escape character to disconnect from a connection. How can I improvise this such that it updates $2 with the status quickly? I am working on Redhat and do not have netcat or expect installed.. ymonad As other stackoverflower's said, I would recommend using nmap or

当新添加的监控主机报telnet service is down on的时候，大家不要惊慌，这个是属于模板中添加了一项监控参数，监控被监控机的telnet服务，有两种解决办法，第一呢就是找到对应的监控项给关闭掉（简单粗暴的方法）按需关闭。如果不用关闭的话就要用第二种方式，那就是解决报错的根本问题。 1、首先查看是那台设备报警，然后去对应的设备上查看是否按照telnet服务和xinetd守护进程服务。 rpm -qa telnet-server rpm -qa xinetd 2、未安装则开始对三个东西进行安装（默认安装rpm镜像中最新版本） yum -y install telnet-server yum -y install telnet yum -y install xinetd 3、安装完成后设置开机自启动 systemctl enable xinetd.service systemctl enable telnet.socket 4、开启telnet服务和xinetd守护进程 systemctl start telnet.socket systemctl start xinetd 5、最后再检查一下zabbix中的报错是否解除恢复了，咱们看到下图已经解除了。 来源： https://www.cnblogs.com/xiangxu-zhao/p/11805019.html

I'm trying to write a script to allow me to log in to a console servers 48 ports so that I can quickly determine what devices are connected to each serial line. Essentially I want to be able to have a script that, given a list of hosts/ports, telnets to the first device in the list and leaves me in interactive mode so that I can log in and confirm the device, then when I close the telnet session, connects to the next session in the list. The problem I'm facing is that if I start a telnet session from within an executable bash script, the session terminates immediately, rather than waiting for
