there is no routing protocols running, and between A and B theres only a switch, they can see each other. > > The machines like A need to know that C can be reached via B.

The best solution is to enable dynamic > routing on B and allow it to announce routing information to the network > for C. there is a static route in A so it can reach C. i can see the packets coming from C to A (ping), and i can see the echo reply from A to C coming out from the A's interface, the problem is that i cant see it coming in from the OSA, its like the OSA dont want to take the packet, or something like that. im trying to use the primary router thing to work, but i cant the osa take the option, i think that maybe the problem is that, because actually the osa is dedicated to my z/vm LPAR and i dont have no more OS's running on it, only my linux is using it. thanks > > Talk with your networking people and see which they would prefer. > > -- db > > David Boyes > Sine Nomine Associates > > > > -----Original Message----- > > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > > Alex Leyva > > Sent: Thursday, March 13, 2003 11:35 AM > > To: [EMAIL PROTECTED] > > Subject: OSA mode and lost packets > > > > > > Hi all, im again here with problems... > > > > i've configured a linux with the OSA-Express dedicated to it, > > using the > > qdio mode, and its running ok, i've defined a virtual nic to the same > > linux, and created a guest lan, then, i brought up another > > linux, defined > > a virtual nic in the same guest lan, both linux can see each other, > > everything its ok, and it look like this: > > > > host_A----host_B----host_C > > > > host_A is outside the z800, is a pc, connected at the same > > switch that the > > OSA. > > host_B is the linux that owns the OSA and have a virtual nic > > host_C is another linux that have a virtual nic, connected to the same > > guest lan that host_B. > > > > ping from host_B to host_A is ok. > > ping from host_B to host_C is ok. > > ping from hots_A to host_C is NOT ok. > > > > i have ip_forward enable, routes are ok, with tcpdump in > > host_A i can see > > that the echo request came from host_C and that host_A send the echo > > reply, in host_B i can see the echo requet going trough the OSA, but i > > cant see the echo reply, i have this OAT in the OSA: > > > > > > ************************************************************** > > ********** > > *** Start of OSA address table for CHPID 00 > > *** > > > > ************************************************************** > > ********** > > * UA(Dev) Mode Port Entry specific information > > Entry Valid > > > > ************************************************************** > > ********** > > LP 2 (ZVM ) > > 00(2000) MPC N/A HALLOLE (QDIO control) > > SIU ALL > > 01(2001) MPC N/A HALLOLE (QDIO control) > > SIU ALL > > 02(2002) MPC 00 No HALLOLE (QDIO data) > > SIU ALL > > FE80::2:5500:39A:B703 > > ::A01:460C > > 03(2003) N/A > > N/A CSS > > 04(2004) N/A > > N/A CSS > > 05(2005) N/A > > N/A CSS > > > > |...+....1....+....2....+....3....+....4....+....5....+....6.. > > ..+....7.. > > 06(2006) N/A > > N/A CSS > > 07(2007) N/A > > N/A CSS > > 08(2008) N/A > > N/A CSS > > 09(2009) N/A > > N/A CSS > > 0A(200A) N/A > > N/A CSS > > 0B(200B) N/A > > N/A CSS > > 0C(200C) N/A > > N/A CSS > > 0D(200D) N/A > > N/A CSS > > 0E(200E) N/A > > N/A CSS > > > > > > i have some questions about this osa: > > why the name is HALLOLE? i dont know where it cames from > > i dont know why i have two UA's with QDIO control > > i dont know why the address appears like > > FE80::2:5500:39A:B703::A01:460C, > > i think that it must be an ip address right? > > > > i think that i must define the linux like the PRIMARY, > > instead of having > > NO, maybe thats the problem with the traffic? > > if so, how i can do that? > > > > thanks > > > > -- > > Alejandro Leyva Rabinovich. > > Jefe de la Unidad Departamental de Soporte Ticnico > > (Administracisn de Mainframe). > > Direccisn General de Informatica. > > Secretarma de Finanzas. > > Gobierno del Distrito Federal. > > > -- Alejandro Leyva Rabinovich.
