The longest telephone record in history

History repeats itself.

On the morning of Monday (Oct 27), everything seemed normal. I saw my colleague's email and was busy with my head. My colleagues in the office soon told me that the files scanned from the copier couldn't be received in the mailbox. I tried it. I wrote a blog post about the same situation before (it seems that the record is indeed useful :). So I checked the Exchange Server immediately. Everything went fine. Then I checked the barracuda Email Firewall, so I was unable to open the Web management interface and ping the IP address. Go to the data center and check the network interfaces of the vswitch and Ba. You cannot change the network cable or port, or restart the BA. Use the monitor and keyboard to directly connect to the BA. You can see and log on to the basic management interface. There is a hardware check on the boot interface, so you can choose to execute and the system starts to detect the memory.

At the same time, report the situation to the manager, and then find the relevant information to call the BA technical support. At first, I had to confirm my identity. On their contact list, I only had one of my managers and one of my colleagues in the office. The manager was not there. When my colleagues started to answer the phone, they could not proceed to the next step. Send a text message to her colleague and ask her to answer the phone. After confirming the identity, I started to provide technical processing. The phone in the IDC had poor listening performance. The other party asked me to open a management interface and I did not hear it again several times. Instead, I logged on to a URL of BA, after downloading a plug-in, you can enable desktop sharing, but you cannot connect to the Web management interface. On the phone, instruct me to restart again and again, switch to the repair mode, and try to establish a remote connection, but BA will not get the IP address, so I will make an automatic repair without damaging the data, because it takes some time, let me call them after the repair is completed. Take advantage of this gap for lunch.

The lunch is over and the repair is over. Ping the IP address is still unavailable. Use the keyboard to log on to the basic management interface and change the IP address from 2.13 to 2.15. You can ping the IP address and change it back to 2.13. Call the manager and ask him to change his login password (this is the only device on the company's network that does not password our IT staff). Then, you can log on to the web page and call Ba again, open remote logon from the management interface, and they can check and determine the fault. Initially, no external emails have been sent to the company's email server via BA since last Friday afternoon. The other party finds that firmware is not the latest version, so the first-level upgrade starts from the current version, after each upgrade, restart the instance and enable remote logon. Finally, even if they were updated to the latest version, the problem was not solved. They had to get off work at and change their shift. They transferred the ticket to the technical staff of the next shift for handling.

When the phone rings, the technicians in the next shift will continue to handle the problem. Remotely log on to the company's computer, open the remote login in BA, and then hand it over to them. The technical staff confirmed that they could contact me before and then hung up the phone. The call was coming in at, but it was still not done. It had to be handled tomorrow morning.

When I arrived at the company on tuesmorning, I still failed to receive any external emails. Then I called BA and the manager sent a notice to all my colleagues. After repeated attempts to automatically repair the data without damaging the data, the technicians asked me to back up the configuration file and make the last move-restore the factory configuration. Then there is a series of firmware upgrades and restarts. Finally, the backup configuration file was imported and everything was recovered at around noon.

Hotmail and Gmail can be used to send test emails to the company, including test emails sent by barracuda technicians. Interestingly, after that, I received several notification emails sent to me by the BA yesterday afternoon to create a repair number. Aren't we able to handle emails that we cannot receive?

One and a half days (Working Hours) Call the phone in the IDC room. If the phone number in the IDC room is not easy to use, you have to keep the receiver in your ears. Most of the time there is no movement in the receiver, the noise in the data center is unclear when there is a dynamic or static traffic. At night, I had to continue to listen to the phone call. This is the longest and most miserable phone record-filing experience in my history.
