Verifying LAN Device Files
Chapter 422
Verifying LAN Device Files
All IP access to LAN devices is done through the files /dev/lan and /dev/snap, which are
symbolically linked to the Data Link Provider Interface (DLPI) device file /dev/dlpi. The
/dev/dlpi file is automatically created at installation time. Verify that the /dev/lan and
/dev/snap files have been created and symbolically linked to /dev/dlpi by entering:
ls -l /dev/snap output will look something like:
lrwxr-xr-x 1 root sys 9 Mar 15 11:59 /dev/snap -> /dev/dlpi
ls -l /dev/lan output will look something like:
crw-rw-rw- 1 root sys 72 0x000077 Mar 15 11:59 /dev/lan
ls -l /dev/dlpi output will look something like:
crw-rw-rw- 1 root sys 72 0x000077 Mar 15 11:59 /dev/dlpi
The major number, shown in the fifth column, must be 72 (decimal) and the minor number,
shown in the sixth column, must be 77 (hexadecimal). If the information differs significantly,
delete the file and recreate it correctly with the mknod command:
mknod /dev/dlpi c 72 0x77
or
insf -d dlpi
