>Number: 3463 >Category: kern >Synopsis: netstat -I packet count increase on sl0 when there's no traffic >Confidential: yes >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Thu May 1 17:30:01 PDT 1997 >Last-Modified: >Originator: Thomas David Rivers >Organization: >Release: FreeBSD 2.2.1-RELEASE >Environment: FreeBSD 2.2.1-RELEASE 386dx-33 with Intel 387; 8 megs ram, 16550 uarts. NE2000 NIC. >Description: netstat -I sl0 when there is an inactive SL/IP connection continues to add to the in and out packet count. Even though no packets are moving through the serial line. Perhaps the packets destined through a different interface (e.g. ed0 in my case) are being counted incorrectly against the sl0 interface? >How-To-Repeat: Do a slip connection, let it quiesce so no SL/IP packets are moving through the sio driver. Run netstat -I sl0, note the Ipkts and Opkts. Wait a second or two (watch the modem lights to make sure nothing actually goes through) Run netstat -I sl0 and notice that Ipkts and Opkts has mysteriously increased. >Fix: >Audit-Trail: >Unformatted:
