IOU Devices not starting

[ccie79]

I have setup EVE and created a simple two router one switch topology to test with. I right click on a device and start and it says started on the right but the device doesn't actually start. The error log is blank. The unl_wrapper.txt file looks something like below. Answers to some other questions you might have.

Yes, I watched the videos.
Yes, I ran the command to fix permissions.
Yes I created a license file. I have created license files for IOU before so I know how to do it.
I can view the license file using the command in your documentation cat /opt/unetlab/addons/iol/bin/iourc

running the command to test the IOU image from a terminal window is successful. I am able to start an IOU image using a set of commands like the one below. It just won't start in an actual eve webpage when I have created a topology.

cd /opt/unetlab/addons/iol/bin
touch NETMAP
LD_LIBRARY_PATH=/opt/unetlab/addons/iol/lib /opt/unetlab/addons/iol/bin/<iosname.bin> 1

IOU nodees need iourc licence sir

[ccie79]

I understand they need a license. As my post indicates I created a license, I can view the license, I can start a IOU device from the command line. I just can't start one from the web page.

[Uldis (UD)]

another thing,
fix permissions, and be sure you did clear browser chache and refresh browser.
all is in FAQ.

[ccie79]

As i indicated in my original post I have done those as well.

Here again is what I have tried.

Yes, I watched the videos.
Yes, I ran the command to fix permissions.
Yes I created a license file. I have created license files for IOU before so I know how to do it.
I can view the license file using the command in your documentation cat /opt/unetlab/addons/iol/bin/iourc

running the command to test the IOU image from a terminal window is successful. I am able to start an IOU image using a set of commands like the one below. It just won't start in an actual eve webpage when I have created a topology.

cd /opt/unetlab/addons/iol/bin
touch NETMAP
LD_LIBRARY_PATH=/opt/unetlab/addons/iol/lib /opt/unetlab/addons/iol/bin/<iosname.bin> 1

[ccie79]

Ok. That was strange. I rebooted the host again and then it started working. I had already tried rebooting once so strange.

I am having the same exact problem. I've generated the license file and implemented the permission fix, and even these commands:

cd /opt/unetlab/addons/iol/bin
touch NETMAP
LD_LIBRARY_PATH=/opt/unetlab/addons/iol/lib /opt/unetlab/addons/iol/bin/<iosname.bin> 1

Having absolutely no luck getting the router to turn on. The message is green that it has started. Ccie79, was it just a reboot that cleared it up? I've restarted my machine (both virtual and physical) and I'm having no luck getting the router to turn on.

[packetloss]

One thing I have noticed, and maybe this helps with troubleshooting, is that whenever I add a new node that it will always fail and give me an error message the first time I try to start it, but then supposedly succeeds each subsequent time I get start the device.

[packetloss]

Nevermind, I figured it out. My iourc file had a .txt appended at the end, and removing the extension along with reboot the VM did the trick.

Lucky you! Unfortunately, my situation still stuck in the same situation, I followed the videos, fixed the permissions, created a license, a NETMAP file and I'm able to run all my IOL images from CLI but when I attempt to run a device into the lab, it says started but nothing happens. I 've also tried with two browser and cleaned the cache. I'm running EVE version 2.0.3. Any Clue ? thanks in advance...
