Problems loading qeth for a Guest Lan
I am attempting to setup a Guest Lan on zVM 4.3 on a z800. I have one Linux machine, lnxrtr1, up and running with a CTC connection to the zVM TCPIP virtual machine. My goal is to have the lnxrtr1 linux machine act be a router for my Guest Lan. I am now trying to get lnxrtr1 to communicate to the Guest Lan. I have defined the LAN as follows: cp q lan qdiolan2 details LAN SYSTEM QDIOLAN2Type: QDIO Active: 1 MAXCONN: INFINITE PERSISTENT RESTRICTEDMFS: 8192ACCOUNTING: OFF Authorized userids: LNXRTR1 SYSTEM Adapter Owner: LNXRTR1 NIC: 7000 Name: BEARS Ready; T=0.01/0.01 17:34:01 In lnxrtr1, I have defined the NIC and have coupled it to the LAN, as shown with the following query commands: CP Q NIC DETAILS Adapter 7000 Type: QDIO Name: BEARS Devices: 3 Port 0 MAC: 00-04-AC-00-00-00 LAN: SYSTEM QDIOLAN2MFS: 8192 RX Packets: 0 Discarded: 0 Errors: 0 TX Packets: 0 Discarded: 0 Errors: 0 RX Bytes: 0TX Bytes: 0 Connection Name: HALLOLE State: Session Established Device: 7000 Unit: 000 Role: CTL-READ Device: 7001 Unit: 001 Role: CTL-WRITE Device: 7002 Unit: 002 Role: DATA CP Q V 7000 OSA 7000 ON NIC 7000 UNIT 000 SUBCHANNEL = 0015 7000 QDIO-ELIGIBLE Now the linux setup information: My /etc/chandev.conf file in lnxrtr1 contains the following: ctc0,0x7100,0x7101 add_parms 0x10,0x7000,0x7002,portname:BEARS qeth1,0x7000,0x7001,0x7002 My /etc/modules.conf file in lnxrtr1 contains the following: # alias eth0 lcs #alias eth1 off alias eth1 qeth alias tr0 off I load qdio and qeth as shown below: lnxrtr1:~ # insmod qdio Using /lib/modules/2.4.17/kernel/drivers/s390/net/qdio.o lnxrtr1:~ # insmod qeth Using /lib/modules/2.4.17/kernel/drivers/s390/net/qeth.o lnxrtr1:~ # lsmod Module Size Used by qeth 138992 0 (unused) qdio 40128 1 [qeth] ipv6 249664 -1 (autoclean) ctc53808 1 (autoclean) fsm 1984 0 (autoclean) [ctc] lvm-mod47280 0 (autoclean) My current ip settings: lnxrtr1:~ # ifconfig ctc0 Link encap:Serial Line IP inet addr:147.185.179.2 P-t-P:147.185.2.158 Mask:255.255.255.128 UP POINTOPOINT RUNNING NOARP MTU:8992 Metric:1 RX packets:465 errors:0 dropped:0 overruns:0 frame:0 TX packets:422 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:53351 (52.1 Kb) TX bytes:53154 (51.9 Kb) loLink encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) When I define the IP configuration for the eth1 with the following command, I lose all IP connectivity and there are no messages in the TN3270 window. lnxrtr1:~ # ifconfig eth1 147.185.179.65 From the TC3270 window I can run ifconfig and get the following: ifconfig ctc0 Link encap:Serial Line IP inet addr:147.185.179.2 P-t-P:147.185.2.158 Mask:255.255.255.128 UP POINTOPOINT RUNNING NOARP MTU:8992 Metric:1 RX packets:1438 errors:0 dropped:0 overruns:0 frame:0 TX packets:1413 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:162163 (158.3 Kb) TX bytes:245515 (239.7 Kb) eth1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:147.185.179.65 Mask:255.255.0.0 inet6 addr: fe80::200:ff:fe00:0/10 Scope:Link UP RUNNING NOARP MULTICAST MTU:1492 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:51 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:0 (0.0 b) TX bytes:14376 (14.0 Kb) Interrupt:21 If I bring eth1 down from the TN3270 window I can logon on with putty.

In a couple of cases I had to use: qeth-1,0x To have the driver pick the device automatically.

That range includes your CTC address, which probably stops it working. Choosing a different address for eth1 would probably be the simplest solution. Richard

THanks to all that responded. The problem was routing. Thomas L.
