UNetLab Putty Connection TimeOut?

Question

linux

Good afternoon,
I can not log in using Putty to UNetLab virtual equipment. I did everything according to the instructions and documentation from unetlab.com.
I deployed the OVA file, registered the ip address, created test pieces of iron, downloaded and uploaded the following IOU images:

-rwxr-xr-x 1 root root 113535540 Jun  7 15:04 L2-ADVENTERPRISEK9-M-15.2-IRON-20151103.bin
-rwxr-xr-x 1 root root 159350476 Jun  7 15:04 L3-ADVENTERPRISEK9-M-15.4-2T.bin

I also generated the iourc.
Registered access rights to images.
The test launch of images works out with a bang:

cd /opt/unetlab/addons/iol/bin
touch NETMAP
LD_LIBRARY_PATH=/opt/unetlab/addons/iol/lib /opt/unetlab/addons/iol/bin/L3-ADVENTERPRISEK9-M-15.4-2T.bin 100

But when I try to connect using putty, I get a black screen and a Connection TimeOut error.
I connect through the Firefox browser, OS Elementary Freya.
Tell me where else to dig.
Thanks in advance for your reply.

Answer 1

If it is useful to someone, then updating the system and the UnetLab package helped me.

Answer 2

Either the SSH server is hanging on a different port, or it is not there at all, or there is no access.

Answer 3

Connects via telnet by default.
The telnet client in Windows 7, 8 and higher is disabled by default, you need to enable it in the components.
Putty has not been set up yet.
