Sumo cannot connect to Tracl server error 104

[Muhammad Waqar Younis]

Hi,

1.I have followed all the steps in veins tutorial. 

2.start sumo first  with this command:  /home/user/veins-4.6/sumo-launchd.py -vv -c /home/user/sumo-0.32.0/bin/sumo.exe

3.But whenever I run veins example from omnet++ , I get an error "could not connect Tracl server". 

This is the error in sumo window:

I have tried different versions of sumo also but there is always this error. Please help me. Thank you

This cannot be. If you are really using the command you said you are using, you should see a line saying "Starting SUMO (/home/user..." instead of "Starting SUMO (/home/waqaryounis..."

Also, I do not think the SUMO binary on your system is called "sumo.exe", but rather "sumo" or "sumoD"

Best,

Christoph

(/home/waqaryounis/sumo-0.32.0/bin/sumo.exe –c

 

This route doesn’t seem to be correct if you are using windows.

 

Usually the path in windows start by the disk, something like /c/…

Hi Muhammad,

If you are working on Linux, you first need to install the Sumo, through terminal: "sudo apt install sumo" in the directory that unpacked Sumo.
