libpcap problem - Not Owner

Timo J — Wed, 07 May 2003 09:34:43 GMT

How to access /dev/lan and/or /dev/dlpi -devices from own program using libpcap functions. Full error message: "Unable to open device(pcap_open_live): recv_ack: promisc_phys: UNIX error - Not owner"

OK, I won't change the owner of those devices. Is there any decent way to access those devices from normal user processes?

Hi

Have a look at sudo which can allow lower level users limited higher functions.

Put your commands in a script or a C program and change the permissions to add suid to root (chmod 4555 ) so that it gains root permission when it runs so it can access /dev/lan.
