.SH NAME

\fBifmon\fR \- network interface monitor

'''

.SH DESCRIPTION

Network interfaces in Linux are not static and cannot be reliably configured

during system startup. \fBifmon\fR addresses this problem by monitoring kernel

events and spawning scripts to configure interfaces once they appear in the

system. Together with its client tool, \fBifctl\fR, it also maintains stable

mapping between identifiable physical devices and their assigned setup scripts,

regardless of non-persistent interface names the kernel uses.

.P

Whenever a new interface appears, say \fIeth1\fR, ifmon spawns

.P

.nf

/etc/net/identify \fIeth1\fR

.fi

.P

which should attempt to identify the physical device behind \fIeth1\fR

and its assigned profile. This is typically done by running

.P

.nf

\fBifctl \fIeth1 \fBidentify\fR

.fi

.P

which then passes profile name back to ifmon. For any device that has

been successfully identified and assigned a profile, ifmon then runs

.P

.nf

/etc/net/mode-\fIprofile\fR

.fi

.P

to configure the device.
