Re: SFTP Authentication Question
you need to place the Z/OS public_rsa key into the authorized key file on the Linux guest and make sure that the SSHD is configured to allow authorization via public key. I don't believe you can provide password in a batch job, but you could try it interactive and see if that is the problem mary_elw...@navyfederal.org Sent by: LINUX-390@VM.MARIST.EDU 12/23/2008 12:32 PM Please respond to LINUX-390@VM.MARIST.EDU To LINUX-390@VM.MARIST.EDU cc Subject SFTP Authentication Question I'm trying to change over from FTP to SFTP on Linux.

"ifconfig -a" output was also identical to what I sent previously. Needless to say, the "rcnetwork start" didn't accomplish much. As for initrd not having the logic to load dqio and qeth, I think it does. I did a "shutdown -r" and watched the reboot very carefully again. The following sequence comes up on the HMC Integrated Console: Setting up network interfaces lo loIP address 127.0.0.1/8 [1A done. lo waiting for mandatory devices lcs-bus-ccw-0.0.0510 lcs-bus-ccw-0.0.0512 __NSC__ 2 0 lcs-bus-ccw-0.0.0510 No interface found lcs-bus-ccw-0.0.0512 No interface found Setting up service network....failed. And then the Samba startup, CUPS startup, Apache startup, etc., all fail. 0.0.0510 and 0.0.0512 are the proper device numbers for the OSA ports. And the OSA card and ports are shared with 4 other LPARs, and they're working just fine, so I am pretty sure it's not an OSA problem. And I don't understand how moving /usr could cause this, unless I deleted something somewhere that I wasn't supposed to. I am completely stumped, which is not all that hard, given what I know about Linux. The only thing I can think of next would be a POR of the 9672, which I can't do until September sometime, or a re-install of SLES 9 SP3, or both. Any/all ideas appreciated. Dave Dave Stuart Prin.

The lsmod command showed that the qdio and qeth modules were not loaded. The modprobe you did looked pretty successful. If you did an "ifconfig -a" after that, eth0 might have shown up, in which case an "rcnetwork start" command should bring things up the rest of the way. I have no idea why your initrd doesn't have the logic in it to load the qdio and qeth modules at boot time. But, once your system is back up and running, you should re-run mkinitrd, and re-run zipl. Then, reboot to make sure things come up the way you expect.

Hipersockets vs qdio
Any one want to advise on the following? I have Z/VM running with three Linux guests (sles9) sharing an OSA card in qdio mode. I also have hypersockets working within the zvm and one linux and two Z/OS 1.6 lpars. I need to add several more linux guest, but I do not want to keep sharing the osa card. I have been reading about the network setup using virtual lans, virtual switches, and just defining a hipersockets nic. I believe using hipersockets will give me better performance. Any one know differently? Would I be better off just defineing the nic with hiper and forget about all the virtual lan stuff? I read that you can do this, but it did not say how. If so How do I do this...be specific ...I'm new at all of this, Linux and VM. I know I can do these commands when logon as maint on vm, but where do I place them to be permanent. -- 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
