hi,
I am using ham for automatically executing my modules or restarting them in case they terminate abnormally or are terminated by a user, and it's working fine on the x86 as well as ppc architecture Very Happy. The problem is when i want to legally shutdown my application. What i am doing is first calling ham_detach_name to deattach the module and then sending it a message to quit, on which the module terminates itself ... this seems to be working fine on x86 and the module terminates .. but when i try to use the same code on ppc the ham_detach_name is successful ( it returns 0 for the first time and returns error if i try to detach it after that ) .. but when the module terminates itself .. the ham restarts the module which isn't desired Sad .. Please help me out on this.

Post subject: Reducing MTU on Ethernet interface - how?  PostPosted: May 29, 2006 - 06:21 PM

I need to reduce the MTU on a QNX Ethernet interface to
allow operation with an upstream router to a DSL line.
(MTU discovery isn't working due to a router firmware problem.)
Is there some way to do this?

(I know about "sysctl -w net.inet.tcp.mss_ifmtu=1", but that
doesn't help; that's for when QNX is running the PPPoE client itself.)

QNX 6.21, x86

(I still keep one QNX desktop machine around from the Overbot project,
to support the students at UC Santa Cruz who now have the Overbot.
and like the Overbot, it runs 6.21.)

Hi John,
may you should set the MTU size if you configure/start your interface.
Using sysctl is too late.
cheers,Peter
