eNSP——通过Telent登录系统

£可爱£侵袭症+ 提交于 2019-12-05 10:58:04
我们先介绍一下Telent是干啥的: Telnet通常用在远程登录应用中,以便对本地或远端运行的网络设备进行配置、监控和维护。如网络中有多台设备需要配置和管理,用户无需为每一台 设备都连接一一个用户终端进行本地配置,可以通过Telnet方式在一台设备.上对多台设备进行管理或配置。如果网络中需要管理或配置的设备不在本地时,也可以通过Telnet方式实现对网络中设备的远程维护,极大地提高了用户操作的灵活性。 这个课题可以模拟一下场景: 公司网络场景,路由器R1是公司机房的一台设备,公司员工的办公区 与机房不在同一个楼层,路由器R2和R3模拟员工主机,通过交换机S1与机房设备相 连。为了方便用户的管理,现需要在路由器R1上配置Telnet使用户能在办公区远程管 理机房设备,为了提高安全性,Telnet需要使用密码认证,只有网络管理员能对设备进 行配置和管理,普通用户仅能监控设备。 开始: 我们现在来建一下拓扑图 1.基本配置 我们配置一下相关信息 配置完,我们ping一下看看能不能ping通(另外俩同理) 2.配置Telnet的密码验证 接下来我们在R1上配置Telnet验证方式为密码验证方式,密码为qiyuan(自己起),并设置验证密码以密文方式存储,在配置文件中以加密的方式显示密码。(命令看图片) 在用户设别R2和R3上使用Telnet连接R1 这样我们就连接好了,可以去R1看一下

How do I use Python libs such as Paramiko for chain connections with Telnet and SSH

拜拜、爱过 提交于 2019-12-05 08:48:32
Similar to a question asked here: SSH and telnet to localhost using python I'm trying to find a solution to the following problem: From Server A (full rights) over Jumhost B (no sudo), I want to connect to several Network devices using Python (one after another is enough, it doesn't have to be in the same time). With SSH only this would be no problem but a lot of devices use Telnet only (I know that this isn't secure, but it wasn't my decision to do it like that). After research I came across multiple solutions for chain SSH connections, such as Paramiko, Netmiko, Pxssh etc. But I can't find a

Bash script telnet to test multiple addresses and ports

﹥>﹥吖頭↗ 提交于 2019-12-05 07:08:46
问题 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

本次工作的内容是实现wince 通过网络连接开发板功能 1,首先理解下两个功能,telnet通过远程控制,ftp一般用于上传下载。 2,添加相应组件,打开core os在CEBASE-Communication Services and Development-servers 添加FTP Server和 Telnet Server。 3,这里还需要增加一个组件Core OS”->”CEBASE”->”Core OS Services”->”Debugging Tools”->”Remote Display Application、 这个组件是方便我们远程开发板桌面。 4,找到注册表文件platform.reg,添加 [HKEY_LOCAL_MACHINE\COMM\TELNETD] "UseAuthentication"=dword:0 "IsEnabled"=dword:1 "AllowAnonymous"=dword:1 "AllowAnonymousUpload"=dword:1 "AllowAnonymousVroots"=dword:1 "DefaultDir"="" "IsEnabled"=dword:1 "UseAuthentication"=dword:0 [HKEY_LOCAL_MACHINE\Comm\FTPD] "IsEnabled"=dword:1

大城市里の小女人 提交于 2019-12-05 01:06:16
1,检查是否已安装 在安装Telnet前先检查系统是否安装了telnet-server和xinetd rpm -qa telnet-server rpm -qa xinetd 2,下载离线安装包 xinetd-2.3.14-34.el6.x86_64.rpm telnet-server-0.17-47.el6.x86_64.rpm telnet-0.17-47.el6.x86_64.rpm 3,上传并安装 rpm -ivh xinetd-2.3.14-34.el6.x86_64.rpm rpm -ivh telnet-server-0.17-47.el6.x86_64.rpm rpm -ivh telnet-0.17-47.el6.x86_64.rpm 4,配置开机启动 配置Telnet,xinetd和telnet开机启动,否则无法启动Telnet服务 systemctl enable xinetd.service systemctl enable telnet.socket 5,启动服务 systemctl start telnet.socket systemctl start xinetd 6,配置防火墙规则 firewall-cmd --permanent --add-port=23/tcp firewall-cmd --reload 来源: https://www

Execute remote commands from Debian to Windows via Telnet

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-04 20:53:55
I am working on remotely executing a command line in Windows from Debian. For that, I tried to use the bash script below. Using the expect tool, it consists in connecting via telnet to the remote server, entering username and password values and sending the command line desired. #!/usr/bin/expect set timeout 20 set name 192.168.1.46 set user Administrateur set password MSapp/*2013 set cmd "TASKKILL /F /IM Tomcat6.exe" spawn telnet 192.168.1.46 expect "login:" send "$user\r" expect "password:" send "$password\r" expect "C:\Users\Administrateur>" send "$cmd\r" The telnet connection is well

VT100 escape sequences: Cursor movement wrap around to end of line

♀尐吖头ヾ 提交于 2019-12-04 19:14:47
I'm creating a Telnet CLI application that is controlled with VT100 escape sequences. So to e.g. navigate the cursor left the <ESC>[D escape sequence is sent from the Telnet server to the client, which may be Putty or Gnome-terminal. Unfortunately, with lines that are longer than the Putty line length, the escape sequence above will not permit navigating the cursor to the line above the current line. An example. Cursor is '|'. Comments are marked with '//' ---------------- >potato| // Now I press left arrow which sends esc sequence to application ---------------- >potat|o // Works as expected.

八十一:memcached之telnet操作memcached

断了今生、忘了曾经 提交于 2019-12-04 18:50:13
先打开telnet服务否则会报错 确认memcached服务已启动 telnet ip 端口 连上以后敲一下回车 常用的命令: 1、set:在memcached中添加一个key->value,如果这个key已经存在,则会替换原来的值,否则做添加操作 set [key] 0[是否需要压缩] 60[过期时间] 7[字符的长度,输入的数据必须等于此长度] 2、get:从memcached中根据key获取数据 get [key] 3、add:给memcached中添加一个key->value,如果这个key已经存在,会添加失败,否则添加成功 add [key] 0[是否需要压缩] 60[过期时间] 7[字符的长度,输入的数据必须等于此长度] 4、delete:删除memcached中的键值对 delete [key] 5、flush_all:删除所有键值对,会直接删除所有数据,需谨慎使用 6、incr:可以给数字加上数字,如age=18, 使用incr age 2,则age=20 7、decr:可以给数字减数字,如age=18, 使用decr age 2,则age=16 8、stats:查看命中概率,即获取到值的概率 get_hits:get命令命中次数 get_misses:get命令未获取到值的次数 curr_items:当前memcached中的键值对个数 total

阿里云=>RHSA-2019:1884-中危: libssh2 安全更新

只愿长相守 提交于 2019-12-04 18:40:48
由于项目构建时间比较长,近期安全检查发现openssh有漏洞。所以要升级openssh到7.9p1版本。由于ssh用于远程连接,所以要谨慎操作。 建议生成环境要先做测试,之后再在生产环境升级。 1 前期准备 1.1 依赖安装 1、 OpenSSL版本:目前OpenSSH7.9不支持OpenSSH1.1.x以上。否则编译的时候会报错。 2、 Zlib1.1.4或1.2.1.2或更高版本 3、 gcc:因为编译需要gcc 4、 openssl-devel:编译时需要 1.2 注意事项 1、 前期多打开一个xshell窗口。保证连接正常。因为可能出现升级失败。结束后要确定好再关闭。 2、 备份sshd_config配置文件(方便后期使用或者方便升级失败使用) 3、 最好关闭防火墙,如不关闭防火墙请开启ssh需要的端口和telnet需要的端口。如果ssh不是22端口最好打开22端口。因为ssh配置文件默认22端口。所以建议关闭防火墙。 2、升级之后要重建xshell的session不然会出项下面提示 1 安装telnet 1.1 安装telnet 为防止openssh升级失败。所以安装telnet。保证openssh升级失败也可以通过telnet连接服务器,进行恢复操作。并不用去机房。 #yum install -y telnet-server #yum install -y xinetd
