But now I'm having a new problem. ssh into the install system is hanging on key exchange (it worked fine when I was using LCS so I'm confident it's not something wrong with ssh itself). On closer investigation it seems possibly MTU related? I can ping from the FTP server (which it is successfully downloading the initial installer components from) into the LPAR with ICMP packets >1400 bytes, but if I use telnet to get a shell on the installer system, I can't ping the other direction with ICMP packets >548 bytes. Why should it be so asymmetric? The CPU is not being chewed up by the LCS, though, and that does seem to have been the issue with bringing dasd online, as that works fine now. Once I cranked the MTU down to the lowest allowable (576 bytes) everything is working. But... gross. Several arbitrary intermediate steps between 1500 and 576 solved nothing; why so low? Once the install completes I shall have to see about experimentally finding the actual limit. ok bear. -- until further notice ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
