Similarly, when I'm unable to ssh to the server, I want to be able to connect somehow remotely when I can't ssh remotely or locally.Īppreciate your input on these two things. Many times I'm unable to connect to the Ubuntu servers due to VFS limit reached so only option is to reboot and when you have server years old then it's scary to reboot so I was wondering if there is still a way to connect to it and increase the limit by somehow connecting to it to prevent the reboot. This will help you to save lots of time when you have to logon to 20-50 terminals a day so I'm a fan of this feature however I also use my Windows machine but I have not been able to find such an option on a windows environment.So.if you're aware of any terminal that might help then please let me know.Ģ. I have been trying to figure out two situations and I hope you can provide some valuable input.ġ on a Mac you can use iterm2 which enables you to send text using a keystroke which has the password saved when you configured it. Now the serial connection should open up and it will be connected with the cisco device. To use this configuration use the following command. Now choose save setup as… and change the name to whatever you like, for example cisco, now save and exit from minicom. Next configure minicom to use that serial port and connect to the cisco device.Ĭhoose serial port setup, change the serial device to /dev/tty0, change the Bps/Par/Bits to 9600 8N1. The seial port in this example is at /dev/tty0 With the help of a loopback test, you can simulate a complete communications circuit. It releases you of the need to connect to additional hardware in order to identify issues with a serial port, cable, or application generating requests. Once installed you need to find out what your serial port connection is. A loopback test is a common way to troubleshoot RS232, RS422, and RS485 communications. This guide is for Debian/Ubuntu but will work with any linux distribution.įirst you need to install minicom this is easy using apt-get or yum, just do the following command. If you need to connect your linux server to a cisco device through the serial port this is the best way to do it.
