Open interactive telnet session from Python

由 半世苍凉 提交于 2019-12-02 08:14:45
问题 I am currently writing a small script in Python which reads some possible connections from a database (triple of node name, telnet IP address and telnet port) and present that to the user to choose to which node to connect. After this selection I want to open an interactive Telnet session, which can be used by the user as if he had manually connected using the telnet command. Somehow I probably will need an escape sequence for that. It only needs to work on Linux OS. I could just call telnet:

Ansi escape sequences as bytes

问题 Could someone run me through the bytes in the ansi escape sequences... I'm coding with pen and paper at the moment, and all the ansi tutorials list the codes as ESC[.... I need to see the actual bytes in the stream. Would one of you gurus with unlimited amount of time devoted to retards like me like to exemplify one or two sequences in bytes? Big thanks! 回答1: The first Google image hit for "ascii table". You're welcome. Just match the characters in the tutorial with the red characters, and

C# - Socket to log on to Firewall

由 大兔子大兔子 提交于 2019-12-02 05:20:09
I wrote an app to automatically connect to our different Firewalls. All of them work with the same frontend. We telnet to the IP and they give the message LOGIN or LOGOUT and ask for a username or password. I used this code: public static void ConnectToFirewall(string strUsername, string strPassword, string strFirewallIp) { IPAddress[] ipaIpAddressCollection = Dns.GetHostAddresses(strFirewallIp); IPEndPoint ipeIpEndPoint = new IPEndPoint(ipaIpAddressCollection[0], intPort); Socket sckSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); sckSocket.Connect

Escape character is '^]'. 解决方法 [root ~]# telnet 192.168.1.22 8080 Trying 192.168.1.22... Connected to 192.168.1.22. Escape character is '^]'. telnet> -- "telnet>"代表进入了telnet命令行窗口 telnet> quit Connection closed. “^” 是Ctrl键的意思！ 1、提示按 " Ctrl + ]"键 呼出telnet的命令行！ 2、然后执行telnet命令 3、退出telnet命令行： quit 。 连接断开，退出成功 来源： https://blog.csdn.net/ShiMengRan107/article/details/102718367

由 放肆的年华 提交于 2019-12-02 04:58:25
I am working on running telnet command on SSH shell session, for obtaining it I used JSch following the official example . I wrote my own code following also this example on StackOverflow this is my code: package Utility; import com.jcraft.jsch.Channel; import com.jcraft.jsch.JSch; import com.jcraft.jsch.JSchException; import com.jcraft.jsch.Session; import java.io.BufferedReader; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.InputStreamReader; public class JavaTelnet { public static void main(String[] arg) { try { System.out.println(telnetConnection(USER_ID

The first Google image hit for "ascii table". You're welcome. Just match the characters in the tutorial with the red characters, and take the corresponding hex value! Escape is 0x1B and [ is 0x5B, so you want 1B5B. You may look for ANSI

telnet安装和使用教程

一、安装telnet 1、检测telnet-server的rpm包是否安装 [root@localhost ~]# rpm -qa telnet-server 若无输入内容，则表示没有安装。出于安全考虑telnet-server.rpm是默认没有安装的，而telnet的客户端是标配。即下面的软件是默认安装的。 2、若未安装，则安装telnet-server，否则忽略此步骤 [root@localhost ~]#yum install telnet-server 　 3、检测telnet-server的rpm包是否安装 [root@localhost ~]# rpm -qa telnet telnet-0.17-47.el6_3.1.x86_64 4、若未安装，则安装telnet，否则忽略此步骤 [root@localhost ~]# yum install telnet 二、重新启动xinetd守护进程 由于telnet服务也是由xinetd守护的，所以安装完telnet-server，要启动telnet服务就必须重新启动xinetd [root@locahost ~]#service xinetd restart 三、测试 我们先来查看TCP的23端口是否开启正常 [root@localhost ~]#netstat -tnl |grep 23 tcp 0 0 0.0.0.0

Sending Commands to Telnet

由 白昼怎懂夜的黑 提交于 2019-12-02 02:41:57
问题 I have a Form that I am making that lets me select a line and reset all of the port on the line. This is done through Telnet. I understand how to Socket and send the IP Address I wish to work with but what I do not understand is sending the commands to log in and reset the ports. The set up is that when one of more check boxes are selected for the different line it calls on private sub to run a line before starting on the next one. I have been web searching for a few days not. The last code I

CentOS 7.6 Telnet服务搭建（Openssh升级之战 第一任务备用运输线搭建）

（以下内容亲手完成，如果需要搬走记得把写博的小白的名字和邮箱一起搬走） 出来玩（学习），总是要还的！ 　　有不明的问题的时候，都来博客园转转，总能找到答案或者灵感，开博3个月都没发一篇帖（不晓得管理员有何感想，不会封我的号吧），不能只是索取没有付出。小白一枚琢磨了半天才扒拉明白Telnet服务搭建（照葫芦画瓢，也要知道葫芦从哪里来的），去繁就简，简单整理一下，分享一下。 　　Linux上的ssh那么好用为什么还要用Telnet这么老旧的东东呢？ 最近被SSH 暴力枚举漏洞弄得头疼，奈何CentOS7最后版本是7.7（里面只openssh7.4，想升级到openssh 8.0），用yum升级ssh是没戏了，rpm的依赖关系（擦汗）。。。。。。，所以只能学编译安装了，第一次使用编译安装这种神器，真怕失手把sshd整挂了，弄个备胎，Telnet是也！ 正文： Setup 1 系统信息 安装 贴下系统信息　　[图1] [root@azeroth ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) 下面是已经安装完成的Telnet版本查询，如果还没有安装的是没有包信息显示的。[图2] [root@azeroth ~]# rpm -qa|grep telnet telnet-server-0.17-64.el7

Linux下Telnet服务的安装配置
