My SLES 8 guests running under ZVM V5.1 on a Z099 work fine.

I am not sure exactly what question to ask the list. NMAP fails to produce any results from any zseries Linux guest. Same 'failure' with different levels of Linux, NMAP and zVM. NMAP just says 'Host seems down.' I tried to bypass any network firewalling by recabling osa to an available router interface. Then I tried to NMAP from Linux guest to another Linux guest and it still fails. Ping, traceroute ,everything else seems to work fine. I did a 'tcpdump -v icpm' and did see two requests and responses to the nmap. Result for 'flags [none]'. Q. Is the tcpdump command above sufficient to see any errors? If I enter arp -v on the console, I get 0 entries. Q. Is this correct? Something i just read but may have misinterperated in Networking with Linux in zSeries was about "layer2 and layer3 traffic can be transmitted over the same OSA CHPID, but not between two hosts sharing the same CHPID!" Dont know if this applies to me for the NMAP test between Linux guests as valid? ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
