Unable to negotiate with x.x.x.x port 22: no matching key exchange found. Their offer diffie-hellman-group1-sha1

Note: You may also see the following error;




Unable to negotiate with x.x.x.x port 22: no matching cipher found. Their offer: aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc

Solution

This is not Apple’s fault, it’s OpenSSH version 7. SHA1 is weak, so support for it has been removed. Which is fine, but all my clients Cisco Firewalls/Routers/Switches are probably all using  RSA/SHA1. So until they re all updated I’m going to need to re-enable SHA1.

Open a terminal windows and execute the following;

Locate the line ‘ #   MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160′ and remove the Hash/Pound sight from the beginning.

Locate the line ‘ #   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc’ and remove the Hash/Pound sight from the beginning.

Then paste the following on the end;

HostkeyAlgorithms ssh-dss,ssh-rsa
KexAlgorithms +diffie-hellman-group1-sha1

Like so;




Theres no reason to reboot, it should work straight away.


Загрузка данных из внешних файлов

Внешняя обработка «Загрузка данных из файла» предназначена для загрузки данных из внешних файлов (*.xls) в справочник «Номенклатура» и документ «Установка цен номенклатуры».

Добавление внешней обработки в конфигурацию

Внешняя обработка подключается из списка Дополнительные отчеты и обработки (Печатные форма, отчеты и обработки - Настройки и Администрирование). В форме подключения настройки Администратор системы может настроить режим публикации (Используется, Режим отладки, Отключена), назначить разделы, в которых обработка будет доступна из списка дополнительных обработок (Указать разделы командного интерфейса)и настроить быстрый доступ пользователей, регулярно использующих данную обработку в своей работе (Настроить быстрый доступ). Поскольку обработка используется только на клиенте, настройка расписания для нее недоступна.

Пользователь может открыть обработку из списка Дополнительные обработки настроенных Администратором разделов программы. 

После открытия обработки с помощью команды Открыть файл необходимо выбрать файл источника данных. После чтения файла данные отобразятся в табличном документе страницы Источник данных формы обработки. Если верхние строки открытого файла не должны обрабатываться при загрузке, например, заголовки прайс-листов, заголовки колонок таблиц,  то необходимо заполнить поле Первая строка данных источника. Обработка данных будет производиться со строки с установленным номером.

CentOS 7 VirtualBox SSH Forwarding
gedesh

Check the IP address by command

[root@hostname ~]# ip address

inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic enp0s3

Then use "Devices/Network/Port Forwarding" dialog box from VirtualBox menu.

And forward 22 port to 222 port from VirtualBox to the LocalHost

Then finally use "ssh root@localhost -oPort=2222" to connect!

       


Cisco and MacOS terminal
gedesh

macbook:user$ cd /dev

macbook:user$ ls -ltr /dev/*usb*

macbook:user$ screen /dev/tty.usbserial-AL03CCPB 9600

To Disconnect

Enter Ctrl+A followed by Ctrl+\


lsof | grep usbserial

 If the port is in use, you will get a response like this (otherwise it will return nothing):

 screen    1575 MacUser    5u      CHR               35,2     0t2405        645 /dev/tty.usbserial-AL03CCPB

 

Note the session number. In my case, it's 1575. Then run:

 

screen -x 1575 (obviously use your session number from the grep)

 

It will return you to your previous screen session. Then use ctr-A ctr-\ to close it properly (will ask you to confirm).

Password Recovery Procedure for the Cisco 2600 and 2800 Series Routers
gedesh

Procedure 1

Complete these steps in order to recover your password:


  1. Attach a terminal or PC with terminal emulation to the console port of the router.

    Use these terminal settings:


    • 9600 baud rate


    • No parity


    • 8 data bits


    • 1 stop bit


    • No flow control


    Refer to these documents for information on how to cable and connect a terminal to the console port or the AUX port:


  2. If you can access the router, type show version at the prompt, and record the configuration register setting. See Example of Password Recovery Procedure in order to view the output of a show version command.

    Note: The configuration register is usually set to 0x2102 or 0x102. If you can no longer access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0x2102.


  3. Use the power switch in order to turn off the router, and then turn the router back on.

    Important Notes:


    • In order to simulate this step on a Cisco 6400, pull out and then plug in the Node Route Processor (NRP) or Node Switch Processor (NSP) card.


    • In order to simulate this step on a Cisco 6x00 with NI-2, pull out and then plug in the NI-2 card.



  4. Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMmon.

    If the break sequence does not work, refer to Standard Break Key Sequence Combinations During Password Recovery for other key combinations.


  5. Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.

    This step bypasses the startup configuration where the passwords are stored.


  6. Type reset at the rommon 2> prompt.

    The router reboots, but ignores the saved configuration.


  7. Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.


  8. Type enable at the Router> prompt.

    You are in enable mode and should see the Router# prompt.


  9. Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory.

    warning Warning: Do not type copy running-config startup-config or write. These commands erase your startup configuration.


  10. Type show running-config.

    The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.


  11. Type configure terminal.

    The hostname(config)# prompt appears.


  12. Type enable secret <password> in order to change the enable secret password. For example:


    hostname(config)#enable secret cisco
    
    


  13. Issue the no shutdown command on every interface that you use.

    If you issue a show ip interface brief command, every interface that you want to use should display up up.


  14. Type config-register <configuration_register_setting>. Where configuration_register_setting is either the value you recorded in step 2 or 0x2102 . For example:


    hostname(config)#config-register 0x2102
    
    


  15. Press Ctrl-z or end in order to leave the configuration mode.

    The hostname# prompt appears.


  16. Type write memory or copy running-config startup-config in order to commit the changes.




Procedure 2

Complete these steps in order to recover your password:


  1. Shut down the router.


  2. Remove the compact flash that is at the back of the router.


  3. Power on the router.


  4. Once the Rommon1> prompt appears, enter this command:


    confreg 0x2142
    


  5. Insert the compact flash.


  6. Type reset.


  7. When you are prompted to enter the initial configuration, type No, and press Enter.


  8. At the Router> prompt, type enable.


  9. At the Router# prompt, enter the configure memory command, and press Enter in order to copy the startup configuration to the running configuration.


  10. Use the config t command in order to enter global configuration mode.


  11. Use this command in order to create a new user name and password:


    router(config)#username cisco privilege 15 password
      cisco
    


  12. Use this command in order to change the boot statement:


    config-register
      0x2102
    


  13. Use this command in order to save the configuration:


    write
      memory
    


  14. Reload the router, and then use the new user name and password to log in to the router.


Example of Password Recovery Procedure

This section provides an example of the password recovery procedure. This example was created with a Cisco 2600 Series Router. Even if you do not use a Cisco 2600 Series Router, this output provides an example of what you should experience on your product.
