Or just make putty use SSH V2. My version defaulted to V1, you can change it in the connection - SSH panel Choose 2 on the Preferred SSH protocol version line. Jay Brenneman Bingo! I was having the same problem from Putty with a new Intel SLES9-beta system and that fixed the problem.

Mark, I would say put the .../present/ directory on the front page. I'd recommend sorting the presentations/papers in reverse chronological order and perhaps adding a date to each entry (perhaps a small script/app to gen the Web page is worth looking into). Keeping the presentations up to date

Just downloaded Samba 3.0.4 to upgrade from Version 2.2.5-SuSE. I am following the normal install procedure. It seems that there are some patches for SuSE. But there is a caveat that goes with that. ... I would like to know how the list members approached the upgrade. Also please advise me

Re: Expanded storage in VM - can it be used for linux swap?

2004-06-22 Thread Michael MacIsaac
When you create a vdisk for swap, it does NOT use any storage. Really. Can you measure this? If you can't ... :)) I was under the impression that creating the VDISKs does take some memory for the data structures, though I'm not sure how much. -Mike MacIsaac, IBM mikemac at us.ibm.com (845)

zfcp module and the SLES-9 beta

Hi, Has anyone gotten the zfcp module to work with the SLES-9 beta? We can insmod the zfcp module with no parameters (not too useful), but with the same command that works on SLES-8: # insmod /lib/modules/`uname -r`/kernel/drivers/s390/scsi/zfcp.ko map=0x400 0x02:0x20040060451609A4

I do recall there was a bug in the dasd driver that called the discipline handlers in the wrong order. We did this with SuSE during the Domino residency last year and I thought we did this with Red Hat too, but don't see it documented in the redbook (SG24-7021). It is documented for SuSE on p

Hello List, I've been grappling with SLES-9 and have already installed it a bunch of times. I thought it would be helpful to share some of my findings. For the most part, I feel the SLES-9 install is an improvement over SLES-8: Pros: (1) Parallel dasdfmt and fdasd of disks - no separate ssh
