gns3 Configurations are deleted/are not saved when restarted

Probably you are using gns3 for the fist time and getting this problem! that when you make you topology, make all configurations, save it and when you restart the gns3 all the configurations are gone away, and only the topology diagram is there?

Don’t worry it is because you are missing one step while saving your Router’s configurations in gns3, that is you have to export the configurations after that you have to save the gns3 file.

Saving Router’s Configurations in gns3 is a two step process

1. Click the FILE menu and Click the import/Export, save the file where you want or choose the default location

2. Click the FILE menu and Click Save.

Step are also shown in the Snap below, Please click to maximize it.

Connection control operation failed for disk 'ide1:0'

I was getting this error while removing Operating System ISO image mounted on the Virtual Machine.

What worked for me, is
1. Uncheck the "Connected and Connect at power on" from Device Status.
2. Then Change the Device type from "Datastore ISO File to Client Device" Radio Button
3. and press OK to save the changes.

Note:- I was able to remove the mounted ISO only by directly logging to the ESXi at https://esxi-ip-address/ui

where it asks

"The guest operating system has locked the CD-ROM door and is probably using the CD-ROM, which can prevent the guest from recognizing media changes. If possible, eject the CD-ROM from inside the guest before disconnecting. Disconnect anyway and override the lock?"

You need to select yes to eject the CD-ROM and then remove the ISO file successfully.

a file I/O error has occurred while accessing vmware converter

While converting physical Windows 7 machine to Virtual machine of infrastructure type, I got this error. The error seems it is unable to read/write source or destination datastore.

I have installed VMware-converter-en-6.2.0-8466193 on Windows 7 physical machine with option locally selected. (not at server/client option)

All of my ESXi servers are connected to the vCenter Server, so I had to use vCenter Server's IP address to send this physical machine to the virtual world.

The issue i found was with the dns resolution to the vCenter Server's hostname. Since I am not using the same dns server on the Windows 7 client machine. So I updated the host entries manually for the vCenter Server's hosname to it IP address.

After adding dns eteries to the hostfile of windows 7, I am not getting this "a file I/O error has occurred while accessing vmware converter" and the migration has started.

How to import Putty Saved Connections to mRemoteNG

Just started using mRemoteNG and its being very cool to connect to different remote connection with different protocols e.g Window Remote Desktop, VNC to Linux, SSH, HTTP connection etc. from a single application.

As new user I configured some remote desktop connection which was quite easy to figure out. But when I wanted to add SSH connections, it came in my mind to import all of the saved connections in the putty. But I couldn't figure it out how can it be done, though it was quite easy and here are the steps.

Open your mRemoteNGCreate a folder if you want segregation of multiple networksCreate a new connectionEnter the IP address of remote server under connection in Config paneUnder the config pane, select protocol "SSH version 2". Once you select protocol to SSH version 2 you are given option to import putty sessions, as shown in the snap below.

In the above snap, I have imported CSR-AWS session from my saved sessions in Putty.
