However only one can listen on a specific interface or all interfaces at once. The only exception is 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 <ICLASS="EMPHASIS">Logging</I> option is turned on (see the <AHREF="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 <TTCLASS="FILENAME">/var/log/iptraf</TT>.</P><DIVCLASS="FIGURE"><ANAME="AEN419"></A><P><IMGSRC="iptraf-logprompt.png"></P><P><B>Figure 1.

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