Re: LINUX Security
Hi Could you explain me, please, what is the reason to remove 'root' name from a system? Local user can read /etc/passwd and find out who is really root, so it is not save us. For remote logins we can disable root. Is this not enough? Thank you. WBR, Sergey
Re: TCPIP vs. OSA
Hello Rob! If you're talking about OSA with QDIO, then I think there are situations where you want to have a virtual router rather than direct access to the OSA device. The IP address assignment is done with the qeth driver, so [... nice explanation ...] QDIO devices get more efficient at higher bandwidth (because buffers get filled better and less handshaking is done). This works out both in CPU time and memory usage. Depending on the shape of network traffic, the savings may be more than the cost of the virtual router. Thank you for explaining that so well. I already had these issues in mind (not so clearly though). In that customer's case, there will be just a few web servers being administered by a very limited number of people. Given your explanations, I belive there's no real reason for not using OSA in their case. Thank you again! -- Gustavo Niemeyer [ 2AAC 7928 0FBF 0299 5EB5 60E2 2253 B29A 6664 3A0C ]

Does Linux/390 take advantage of any of the VM facilities when running under VM vs. in an LPAR? I'm thinking especially of the handshaking that is possible with paging. I.e. Linux thinks the page is in memory, but VM has it paged out. I think this is done with VSE and I remember it back in the OS/VS1 days as well. What about other VM-only facilities? Yes, pseudo page fault support is there already. When a process gets blocked because the particular page is paged out by VM, the kernel gets a chance to run another process. Recent changes to z/VM improved the PFAULT support. I have not seen numbers about how effective this is for Linux, but it is enabled by default when you run in a virtual machine. In fact, virtual memory itself as provided by z/VM is already a benefit over LPAR since it allows the Linux guests to breathe. The other thing is the shared kernel support that has been there for some time now. This allows you to put some 2MB of the kernel in shared pages and thus reduce the footprint of your penguins. And the dasd driver can use Diagnose I/O instead of SSCH and exploit MDC and other z/VM benefits. There have been some problems with that part of the driver in the past, but it looks like the current code works. Rob

Trying to cough up the $$$ for Z/VM also. The distribution of SSH that I tried was on http://s390.nichols.de/ssh/index.html. Page says the archive included binaries compiled under OS/390 2.9, but I sure as hell couldn't find them or figure out where they were in a different archive. If anyone is interested in trying to get Open SSH working under OS/390\Z/OS and unix system services with GCC or some other open source C compiler (if there is one) I think we could do something very beneficial to the OS/390 AND linux/390 Communities. Why IBM does not include open SSH as part of of the base is beyond me. |-+ | | paultz | | | [EMAIL PROTECTED]| | | Sent by: Linux on| | | 390 Port | | | [EMAIL PROTECTED]| | | IST.EDU | | || | || | | 12/16/2002 11:44 | | | AM | | | Please respond to| | | Linux on 390 Port| | || |-+ --- ---| | | | To: [EMAIL PROTECTED] | | cc: | | Subject: Re: Linux/390 and z/VM interactions | --- ---| Jim, Yes, quiesce your Linux prior to doing your DFDSS backup of your CDL DASD. As to SSH, I assume you are referencing the SG245944 Redbook, chapter 25? I know it's out there, I just haven't gotten to it yet. I'm trying to find some free time to do similar automated tasks via SSH. I'll be interested to hear from you if you beat me to implementing SSH on your z/OS system (don't have z/VM). Best regards, Paul From: James Melin Subject: Re: Linux/390 and z/VM interactions. Just so I can wave a 'see, these people say it needs to be done this way' paper at my head sysprog I assume to use CDL and back up linux volumes with DFDSS 1) the volumes need to be 'avaiable' to the OS/390 image doing the backup, and that 2) Linux needs to be quiesced and halted in order to get a good backup of the devices? Lastly, has anoyne gotten Open SSH to work for OS/390? I'd like to use it to have automation be able to logon to Linux etc, and do stuff but I want encrypted shell. I've not been able to get the one S/390 port to work as we don't have the IBM C compiler. Has anyone ported GCC to the Unix side of OS/390 (Z/OS)? If so can the open SSH be made to work? Thanks.

(please) Tell IBM about your VM Linux on VM Education needs
(cross-posted to vmesa-l, ibm-main, linux-390) Hello, Please help us to understand your education needs (and those of your staff) by providing your input and guidance. For starters, these are the newly-updated VM course offerings from IBM. - Installing, Configuring and Servicing z/VM for Linux Guests (ZV060) - z/VM Linux Connectivity Management (ZV100) 1) Do these courses combined with either a zSeries Tech conference or SHARE or GSE meet your VM education needs? What about the VM needs of your staff members? 2) Please tell us the additional z/VM and Linux on VM related topics for which you need in-depth education? 3) Any comments on the delivery method (formal classes, online), location, and cost? 4) Do you have (or plan to have) new-to VM staff who will need the CP/CMS basics? Please respond via way that is most comfortable for you. - directly to me - or VM web feedback: http://www.vm.ibm.com/forms/feedback.html - or here on the listserv if you don't mind sharing the information and/or encouraging discussion on this topic. I will share your responses with my colleagues in IBM Learning Services for consideration in educational offerings and course development, and also I will keep them in mind when assembling the agenda for the 2003 zSeries Technical Conferences. We look forward to hearing from you. Thank you. Regards, Pam C
