Good point ! BTW; for your squid problem I would use a local DNS with 
forwarders for that, AFAIK on hobbes there are some bind versions (bind 
== DNS server) around. But if you never configured a DNS server, I am 
sure you surely want to avoid this. Beside that I see your point.

At least ovverides of DHCP options should should normally be solved with 
DHCP methods,  just disable the option in the DHCPCD.CFG. But I see a 
problem where one would want to use different DHCP configurations for 
different connections.
Unfortunately it seems not to be possible to use different dhcpcd.cfg 
files, AFAIK one cannot specify a separeate config file :-(  And I don't 
dare to set ETC to something different  to launch a DHCPCD with a 
separate config - you never know what will happen (not work) then. 
Again, the implementation of IBM is narrow-minded and outdated (same 
with allowing DHCP only for one interface at a time).


Including connect and disconnect scripts will be quite a major change 
and take some time. Moreover, it may make sense to use REXX extension 
scripts as a script solution. XWLAN would create an own REXX environment 
(e.g. "XWLAN" or "XWL") so that REXX scripts can easily access internal 
XWLAN variables, like querying the settings of the current profile etc. 
 From those application specific REXX files, of course, OS/2 commands 
can still be executed. Beside that, of course plain CMD files could be 
supported as well, possibly passing XWLAN values as environment 
variables to the called process.

thanx, Christian
