Segmentation fault (core dumped)
There error is: Could not open ro target file: /home/sai/.shadow/lib/libshadow-plugin-torctl.so
Make sure you have successfully built and installed shadow-plugin-tor, and make sure that the file exists in the correct location: /home/sai/.shadow/lib/libshadow-plugin-torctl.so.
If so, then the suggested fix is Try adjusting your system's max_map_count., which is explained further on the wiki. See also #58 where someone else had the same issue. (You may need to log out/in or restart after updating the map_max_count to make sure you OS applies the change.)
Please let us know if you get things working.
Thanks it is working after i reinstalled shadow.I would like to know if there is a website that has database for tor simulation in shadow that has varied number of relays, file servers and clients or should we create our own network configuration files for simulation
Glad you got it working!
There is no database of Shadow-Tor simulation network configurations. I would like to create a page on the wiki that people can use to link to their own configurations, but so far that doesn't exist.
The most recent configurations that I have used are posted here:
https://tmodel-ccs2018.github.io/
(See Shadow host configuration at the bottom of the page.)
These are somewhat resource intensive, so it might be better to generate your own.

Thanks for the information.
I tried to create the simulation config file using
python ~/shadow-plugin-tor/tools/generate.py --nauths 1 --nrelays 20 --nclients 200 --nservers 20 --fweb 0.90 --fbulk 0.10 --nperf50k 100 --nperf1m 50 --nperf5m 50 /home/sai/shadow-plugin-tor/tools/parsealexa.py /home/sai/2018-10-20-18-00-00-consensus /home/sai/server-descriptors-2017-01 /home/sai/extra-infos-2017-01 /home/sai/clients.csv
but the data is not generated and the terminal is still There is no errors. How much time is estimated for this process?
There is a lot of data to process so it can take some time (maybe a few hours). Please be patient.

how do i fix this?
