Telnet - Remote login service, unencrypted text messages Here are some of the most common ones:ДЇile Transfer Protocol (FTP) Data TransferДЇile Transfer Protocol (FTP) Command Control The Internet Assigned Numbers Authority (IANA) has assigned port numbers to commonly used services like SSH, FTP, HTTP, HTTPS, and others. You may use the -p option to specify another port number otherwise, SSH will defaultВ to 22. In this example, -v stands for verbose, andВ you should see output similar to this: debug1: Connecting to port 22ДЄs shown, SSH is trying to connect to using port number 22. For example, to connect to the host via SSH, I would use this command: ssh -v Well-known ports (also known as system ports) are numbered from 0 through 1023. Port numbers are divided into three ranges: well-known ports, registered ports, and dynamic or private ports. Other services use this port number to communicate with the service or app. Ports are identified with positive 16-bit unsigned integers, ranging from 0 to 65535.

In simple terms, if a software application or service needs to communicate with others, it will expose a port. It is also possible for different services running on the same computerВ to expose various ports and communicate with one another using these ports. When a computer system seeks to connect to another computer, the port serves as a communication endpoint. Witin computer networking,В ports serve a similar purpose.

Therefore, I sshвЂ™d to the IMM as USERID/PASSW0RD, factory default credentials and created a login profile. The configuration backup and restore did not include the login credentials. asu rebootimm -kcsДЇollowing the reboot, I was able to ping the IMM IP address. I expected the IMM to start working right after the restore but it did not. I saved the IMM configuration before the reset using asu save backup_file -group all Next I restored backup configuration using the kcs interface. ssh inside the IMM cli, I used clearcfg command to reset the IMM to factory default configuration. Then I realize I can ssh to the IMM using the LanOverUsb interface from the Service Console. The asu utility has resetrsa which does not work on IMM. ThereвЂ™s got to be another way to reset the IMM to default settings. I am 99.9% certain I will not break anything but I choose to be extra cautious. I thought of taking my desk monitor and keyboard but this isnвЂ™t my home lab. The host is housed in a small facility that does not have kvm or crash kart.

We even ran a cable between the IMM port and a laptop.ДЄs the host is classic ESX 4.1, we used the asu utility from the host to check the configuration. The MGMT NIC had green light, was blinking and our network guy saw they were exchanging packets. Our network guy validated the switch configuration. We have seen this before and managed to solve it by resetting the IMM via LanOverUsb or cold restart of the server- graceful shutdown of ESX(i), followed by unplug, plug both power supplies but not this time. We have one server where we cannot reach the IMM remotely. A part of our pre-upgrade checklist is to ensure we have IMM access.

#Imm port upgrade#

It is going to be a two step process, the first of which will be upgrade to 5.1 using the ISO. We are going to upgrade a handful of ESX 4.1 hosts to 5.5 or 6, if the hardware supports.
