z/VM and SuSE Linux Ver 8

[Raymond Noal]

Dear Lists:   Our z/VM and Linux testing goes in about 6 month cycles. The last time we used SuSE Linux under z/VM, we had z/VM 5.1. We are now using z/VM 5.2 at the 0501 RSU maintenance level.   All of a sudden now (?), we can no longer connect to our Linux virtual machines using PuTTY. The network guys tell me that they can see the request going to the z/VM TCPIP address and being rerouted to the appropriate IP address for the Linux virtual machine, but there is no response from Linux. With my virtual Linux machine running I can not PING the z/VM TCPIP stack nor can I ping my Linux machine from the MAINT virtual machine. When I try to PING TCPIP from Linux, the Linux console stops working.   Has anyone else had a similar problem? Have TCPIP parameters changed that much between z/VM 5.1 and 5.2?   Here is my TCPIP profile statements –   DEVICE OSA0 OSD 00B0 PORTNAME OSACHP86 PRIROUTER                         LINK ETH0 QDIOETHERNET OSA0                                                                                                                        DEVICE ZVMLAN1 OSD 10B0 PORTNAME ZVMLAN1                                 LINK ZVMLAN1 QDIOETHERNET ZVMLAN1                                                                                                                 ; (End DEVICE and LINK statements)                                       ; ---------------------------------------------------------------------- HOME                                                                       172.17.51.026   ETH0                                                      172.17.230.1    ZVMLAN1                                                ; (End HOME Address information)                                         ; ---------------------------------------------------------------------- PRIMARYINTERFACE ETH0                                                     ; ---------------------------------------------------------------------- GATEWAY                                                                  ; Network       First           Link     MTU  Subnet        Subnet       ; Address       Hop             Name     Size Mask          Value        ; ------------- --------------- -------- ---- ------------- ------------ 172.17.50.1     =               ETH0     1500 HOST                       ; 172           =               ZVMLAN1  1500  0.255.255.0 0.17.230.0    172.17          =               ZVMLAN1  1500 0.0.255.0     0.0.230.0    ;                                                                        DEFAULTNET      172.17.50.1     ETH0     1500  0                         ; (End GATEWAY Static Routing information)                               ; ---------------------------------------------------------------------- START OSA0                                                                START ZVMLAN1                                                            ; (End START statements)                                                 ; ----------------------------------------------------------------------     Here is the console log from the Linux IPL   ..done""                                                                        Setting up network interfaces:""                                                    lo                                                                          ..done""                                                                            eth0      qdio: loading QDIO base support version 2 ($Revision: 1.145.4.1 $/ $Revision: 1.66.4.1 $)                                                          IPsec Security Association Database (SADB): initialized.                        IPsec Security Policy Database (SPD): initialized.                              IPsec PF_KEY V2: initialized                                                    IPv6 v0.8 (usagi-cvs/IPsec6 based StS) for NET4.0                               IPv6 over IPv4 tunneling driver                                                 qeth: loading qeth S/390 OSA-Express driver ($Revision: 1.337.4.7 $/$Revision: 1 .113.4.2 $/$Revision: 1.42.4.1 $:IPv6:VLAN)                                      qeth: allocated 0 spare buffers                                                qeth: Trying to use card with devnos 0x10B0/0x10B1/0x10B2                       qeth: Device 0x10B0/0x10B1/0x10B2 is an OSD Express card (level: V522)          with link type Gigabit Eth (portname: ZVMLAN1)                                  IP/Netmask:    172.17.230.2 / 255.255.255.0                                     ..done""                                                                          My Linux machine is IP address 172.17.230.2.   There is also no PORT statement entry for port 22 (PuTTY SSH).
