[AGENT++] how to specify the source address for traps

[Antoine Gatineau]

Hello all,

I have a problem : I run an agent++ client in a chrooted environment
with user rights. The problem is that NotificationOriginator is not able
to give a valid address (address = 255.255.255.255).


I didn't find functions to generate traps with a specific source
address, Is there one? However, I came with a solution to force the
source address when creating the pdu. Here is what I did :

I overloaded all the function used to generate traps from :
	virtual int Mib::notify(const NS_SNMP OctetStr&, const Oidx&, Vbx*,
int, unsigned int=0);     (mib.h)

	virtual int NotificationSender::notify(const NS_SNMP OctetStr&,const
Oidx&,Vbx*, int, unsigned int=0) = 0; (mib.h)

	virtual int NotificationOriginator::notify(const NS_SNMP OctetStr&,
const Oidx&, Vbx*, int, unsigned int=0);   (notification_originator.h)

	int generate(Vbx*, int, const Oidx&, unsigned int, const Oidx&, const
NS_SNMP OctetStr&);   (notification_originator.h:267)

	int NotificationOriginator::send_notify(ListCursor<MibTableRow>& cur,
NotificationOriginatorParams& nop, int notify);
(notification_originator.h)



To :
	virtual int Mib::notify(const NS_SNMP OctetStr&, const Oidx&, Vbx*,
int,UdpAddress, unsigned int=0);

	virtual int NotificationSender::notify(const NS_SNMP OctetStr&, const
Oidx&,Vbx*, int,UdpAddress, unsigned int=0) = 0;

	virtual int NotificationOriginator::notify(const NS_SNMP OctetStr&,
const Oidx&,Vbx*, int,UdpAddress , unsigned int=0);

	int generate(Vbx*, int, const Oidx&, unsigned int, const Oidx&, const
NS_SNMP OctetStr&,UdpAddress srcAddr);

	int NotificationOriginator::send_notify(ListCursor<MibTableRow>& cur,
NotificationOriginatorParams& nop, int notify,UdpAddress);

The UdpAddress parameter represents the source address a want the pdu to
use.
in send_notify, I added the line :
	pdu.set_v1_trap_address(srcAddr); srcAddr = UdpAddress parameter
	
	
now, I just have to call :
	UdpAddress source(SourceParameters);
	mib->notify("context", oid, vbs, sz,source);

instead of :
	mib->notify("context", oid, vbs, sz);


Could you tell me if there is a best solution? 

Thank
