(1) AIX 4.x's version of BPF is undocumented and somewhat unstandard; the
|
|
current BPF support code includes changes that should work around
|
|
that, but, lacking an AIX machine on which to compile it, we don't
|
|
know whether the BPF support for AIX will compile.
|
|
|
|
If it doesn't, or if the workarounds fail to make it work correctly,
|
|
you should send to tcpdump-workers@tcpdump.org a detailed bug report
|
|
(if the compile fails, send us the compile error messages; if it
|
|
compiles but fails to work correctly, send us as detailed as
|
|
possible a description of the symptoms, including indications of the
|
|
network link-layer type being wrong or time stamps being wrong).
|
|
|
|
If you fix the problems yourself, please send to patches@tcpdump.org
|
|
a patch, so we can incorporate them into the next release.
|
|
|
|
If you don't fix the problems yourself, you can, as a workaround,
|
|
make libpcap use DLPI instead of BPF.
|
|
|
|
This can be done by specifying the flag:
|
|
|
|
--with-pcap=dlpi
|
|
|
|
to the "configure" script for libpcap.
|
|
|
|
(2) Also, it is a good idea to have the latest version of the DLPI
|
|
driver on your system, since certain versions may be buggy and
|
|
cause your AIX system to crash. DLPI is included in the
|
|
fileset bos.rte.tty. I found that the DLPI driver that came with
|
|
AIX 4.3.2 was buggy, and had to upgrade to bos.rte.tty 4.3.2.4:
|
|
|
|
lslpp -l bos.rte.tty
|
|
|
|
bos.rte.tty 4.3.2.4 COMMITTED Base TTY Support and Commands
|
|
|
|
Updates for AIX filesets can be obtained from:
|
|
ftp://service.software.ibm.com/aix/fixes/
|
|
|
|
These updates can be installed with the smit program.
|
|
|
|
(3) After compiling libpcap, you need to make sure that the DLPI driver
|
|
is loaded. Type:
|
|
|
|
strload -q -d dlpi
|
|
|
|
If the result is:
|
|
dlpi: yes
|
|
|
|
then the DLPI driver is loaded correctly.
|
|
|
|
If it is:
|
|
dlpi: no
|
|
|
|
Then you need to type:
|
|
strload -f /etc/dlpi.conf
|
|
|
|
Check again with strload -q -d dlpi that the dlpi driver is loaded.
|
|
|
|
Alternatively, you can uncomment the lines for DLPI in
|
|
/etc/pse.conf and reboot the machine; this way DLPI will always
|
|
be loaded when you boot your system.
