Hello.I installed quartus 15 in ubuntu.And I want to know how to find my real Network Interface Card ID .And how to start modelsim alone?

Use the ifconfig utility to find the NIC ID on Linux.

• At a command prompt, type:

/sbin/ifconfig eth0

And how to start modelsim alone?

Perhaps the below link helps.

Try

/sbin/ifconfig -a

If ifconfig -a does not list eth0 means that your wired adapter hasn't been found. Things to check:

• lspci - is you network adapter listed?
• Reboot and enter bios setup. Check if the built in network adapter is enabled.
