how to find "int 0x80" address?

st flag

I had tried to hook "int 0x80" system call for a testing in x86_64 ubuntu system. The idea is: write a simple drive module in order to entering system module, in system module load idt table and find out 0x80 call function address(use: function_address = idt_addr.base + 0x80service_offset)

But when i do these the address we got is not correct. I also dump the machine code [function_address, function_address + 32 bytes] and use decodecode script translate to assembly lauguage try to find address accoding jump instruction.

so how is correct way i can find out "int 0x80" function address ?

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
