You can use a RJ-45 to DB-9 Female if your computer has a serial port. Connecting to Cisco from Linux and FreeBSD Add user to the Dialout groupDescription: to connect your computer to a Cisco device via its console port, you usually need a RJ45 rolled cable. You can use screen, although Minicom (or a GUI program) offer more.Application Minicom to enter AT command modem. Many other documents explain how you can make a serial connection fromYou just need a serial to USB adapter, the right driver, and some Terminal software. You may have to connect to some devices via a serial connection: as an example, on a GNU/Linux platform, you can use Minicom, GtkTerm, Putty, and other programs, to connect to the Console port of a Cisco router: and then access the IOS CLI through an 'out of band' connection.
Minicom To Cisco Via Serial Install A Serial
After pressing the "E" key, the communication parameter window will open (Fig. If a connection to a specific sequential port is displayed, no changes are needed.It is also necessary to configure the E (BPS / PAR / BITS - speed / parity / stop bits) in accordance with the requirements of the modem and the system to which the Internet provider system will have (as a rule). 18.9, check its links using the LS -I / DEV / MODEM command. If the modem is connected to the second sequential port, you can specify / dev / ttys1 due to the use of minicom for outgoing compounds.If the serial port is already connected to / Dev / Modem, as shown in Fig. First of all, you must install a serial device by pressing the "A" (Serial Device) key and specifying a suitable device file. 18.9).To change any value, press the key with the corresponding letter.
For example, for a modem with a speed of 14.4 kbps, set value 57,600 bits, for 28.8 kbps - 115,200 bits / s. As a rule, this value is four times higher than its nominal speed. To modify any of them, press the key with the corresponding letter.For the Speed \u200b\u200bparameter, select the value equal to the maximum modem speed when the data is compressed.
By executing the EXIT menu command, complete the configuration procedure and continue working in the MINICOM terminal emulator window (Fig. Save the modified set of parameters as the default configuration by running the Save Setup AS DFL menu command (Save Parameters as DFL). Another press of Enter leads to return to the main menu.This information should be enough to test the modem. The correct values \u200b\u200bof the remaining parameters, find out the system administrator to which it is to be connected.Return to the Serial Port Setup window by clicking Enter.
Installation is different depending on the distribution. To connect to the Cisco console, you must install the Minicom package. Initially, you need to connect the console cable to the COM port of the machine, with the Linux installed OS and the port console on Cisco. The answer must be the message "OK"The article is considered the simplest way Connections to the Cisco Terminal from Linux medium. To make sure this again, enter AT and press ENTER.
At first, you need to find and connect the computer and switch to the appropriate cable cable (via COM port or USB adapter) computer. ).Setting up different switches, routers and other equipment is usually done through a serial COM port (RS232). In this example, this / dev / ttys0 is the address of the COM1 port.As a result, you need to get the following settings:We save the modified configuration as default settings in the Mainicom main menu, or as a configuration with a specific name (Save Setup as. We change the serial port (Serial Device) to the port to which Cisco equipment is connected. We go into configuration of the serial port (Serial Port Setup) and change the value speed / parity / bits (BPS / PAR / BITS) by 9600. Setting MinicomFor the proper operation of Minicom with Cisco, it is necessary to produce its initial setting.
No.Save the configuration as default settings in the Main Menu MINICOM (Save Setup AS DFL), or as a configuration with a specific name (Save Setup AS. When connecting through the MINI-USB connector, the port may be as / dev / ttyacm0.Help by commands can be found by pressing Ctrl + a then Z.As a result, we get standard settings For Cisco and HP ProCurve:A - Serial Device: / Dev / Ttys0 B - Lockfile Location: / Var / Lock C - Callin Program: D - Callout Program: E - BPS / Par / Bits: 9600 8N1 F - Hardware Flow Control: YES G - Software Flow Control : No. In this example, this / dev / ttys0 is the address of the COM1 port. Put from the package under Debian (Ubuntu):To minicom saw Cisco it needs to be properly configured to start with the key:We go into configuration of the serial port (Serial Port Setup) and change the values \u200b\u200bof speed / parity / bits (BPS / PAR / BITS) to 9600 8N1.We change the serial port (Serial Device) to the port to which the equipment is connected and adjust the flow control parameters (Flow Control). To connect under Linux you need to put minicom program.
IT IS Used to Talk to External RS-232 Devices such as Mobile Phones, Routers, And Serial Console Ports. Introduction.Minicom Is a Text-Based Serial Port Communications Program. Settings through the CU utilityCHOWN UUCP / DEV / TTYUSB0 CU -S 115200 -L / DEV / TTYUSB0If you do not set chown rights to the device file, you can get a message:The main advantage of the Cu utility is that it works equally well under Linux and under FreeBSD only the names of the devices differ.Chown UUCP / DEV / CUAA0 CU -S 115200 -L / Dev / Suaa0The only one needs to select the device file correctly where the device is connected. However, sometimes the connection parameters are written directly on the device next to the console port. So before connecting you need to carefully read in the documentation, what speeds and flow control should be set. The speed of 19200 sometimes 115200 is used on 3COM switches (now HP) and any other speed they do not understand.
Next, ENTER IN A Terminal Enter: Sudo Minicom -s.One Will Next Choose "Serial Port Setup". Which We Will Need in Order to Use Minicom. In The First Section Above IT IS Ttyus0, The Other Is Ttyusb0. Using the ProgramIN ORDER TO FIND THE NAME OF YOUR PORT (S) ENTER THIS COMMAND IN TERMINAL: dmesg | Grep Tty.If IT IS A Direct Serial Connection, The Output Will Be Something Like This: Console Enabled Serial8250: TTYS0 AT I / O 0x3F8 (IRQ \u003d 4) IS A 16550A 00:08: TTYS0 AT I / O 0x3F8 (IRQ \u003d 4) IS A 16550A Audit ( 1243322582.732: 2): Type \u003d 1503 Operation \u003d "inode_permission" Requested_mask \u003d "A ::" DENIED_MASK \u003d "A ::" NAME \u003d "/ DEV / TTY" PID \u003d 5705 PROFILE \u003d "/ USR / SBIN / CUPSD" NAMESPACE \u003d "Default"For a USB-to-Serial Adapter, One May See: Console Enabled USB 4-3: PL2303 Converter Now Attached to TTYUSB0What We Are Interested in Is The Name of the Serial Port.
Once Saved, One May Choose Exit, and One is at the Minicom Prompt. Once Configured, One May "Save Setup AS DFL", Which Will Save the As The Default Configurations for Future Connections (/etc/minicom/minirc.dfl). Once These Have Been Adjusted, One May Want to Also Go to the Modem and Dialing Menu and Remove All Information in Setting Options a Through I.
Press "Enter" to Save the Changes. By Default This Will Be Saved AS "Minicom.log", But Change It To Whatever You Like With the "A" Key. SELECT "FILENAMES AND PATHS" AND PRESS "F" (LOGGING OPTIONS).
