Re: [Freeipmi-devel] ipmi_lan_open_session() question

[Albert Chu]

Hi Jim,

I think the open_lan_session() function was created a long time ago as a
convenience function for libfreeipmi users.  I know that the ipmiutil
author (ipmiutil.sourceforge.net) atleast uses it.  I suppose it has
never been used for the FreeIPMI tools because:

A) some tools like bmc-config only work in-band
B) some tools like ipmipower need to work more reliably/quickly and
therefore "manually" setup a lan session

As for the reason why your code isn't working with MD5, I'm guessing:

sizeof(password),

should instead be

strlen(password)

???

I see a few corner cases in the code.  In particular the fallout case
for "goto error;".  I'll let AB talk about this since its his part of
the lib :P
