However only one can listen on a specific interface or all interfaces at once. This applies to all facilities except the general interface statistics, which is still restricted to only one instance at a time.</P ><P > Because of this relaxation, each instance now generates log files with unique names for instances, depending on either their instance or the interface they're listening on. If the <I CLASS="EMPHASIS" >Logging</I > option is turned on (see the <A HREF="config.html" >Configuration</A > chapter), IPTraf will prompt you for a log file name while presenting a default. You may accept this default or change it. Press Enter to accept, or Ctrl+X to cancel. Canceling will turn logging off for that particular session.</P ><P > If you don't specify an absolute path, the log file will be placed in <TT CLASS="FILENAME" >/var/log/iptraf</TT >.</P ><DIV CLASS="FIGURE" ><A NAME="AEN411" ></A ><P ><IMG SRC="iptraf-logprompt.png"></P ><P ><B >Figure 1.

You can override the defaults with the <TT CLASS="COMPUTEROUTPUT" >-L</TT > parameter.
