Re: Linux default permissions
In /etc/profile /etc/csh.login etc. change the umask from 022 to 026. On SUSE the default is 022 which says the default permissions for creating non-executable files is the exclusive or 022 against 666 - 644. Changing it to 026 should give you 640 - rw-r-. -Original Message- I've asked a simular question before this and the concensus was to use ACL instead of permissions, but... The default permissions defined when a file is created, seems to be +644. This allows any Linux user to read the file, even the user isn't the owner or isn't a member of the same group. That's not too good. I would like to change something, somewhere, so that for certain users, any files they create have permissions set to something like +640, or perhaps +600. I can keep FTP users from changing to someone else's directory and reading. Samba and Putty users seem to have the unrestrictive ability to change directories to other users.

install -c -m 750 hcp ${prefix}${bindir}
clean:
rm -rf *.o *~ core mongen monstat actgen hcp diag0 *.ko *.cmd
.tmp_versions
The build process is:
1. For the device driver -
make -C /lib/modules/`uname -r`/build M=`pwd` SUBDIRS=`pwd` modules
You need to have the kernel source installed and at last a make *config
performed.
This will generate cpint_mod.ko which can be installed via:
make -C /lib/modules/`uname -r`/build M=`pwd` SUBDIRS=`pwd` modules_install
Issue -
depmod -a
Then modprobe cpint_mod to load it. In SLES9 SUSE have decided that major no
107 is
used for cpint so you could put an entry into /etc/modules.conf to get the
driver
loaded automatically (i.e. sans cpint_load).
2. For the utilities (hcp etc.)
make tools
The 2.3 package should be available shortly. In addition to the ioctl fix it
contains a
fix for the diag0 driver on 64-bit systems.

FCP Access Control
One of the interesting items for SCSI users is the following: Configuration Utility: The Configuration Utility for FCP LUN Access Control is designed to be a Linux user space application which may be used to configure the FCP LUN Access Control. To define and activate LUN Access Control, you would create an access control table that describes the access rights in XML format. In this table, you would define access rights to storage controllers and devices in the SAN and identify devices to be shared in read-only mode. The Configuration Utility for FCP LUN Access Control is required to process the access control table, verify proper specification of the rules, and activate the access control functions in the FCP channel. The Configuration Utility for FCP LUN Access Control is designed to be a package consisting of user documentation and sample files with a skeleton to help you generate an XML-format access control table, and the utility program itself. The program is intended to provide a command line interface (CLI) and be supported by Linux on zSeries. The Configuration Utility will be provided for download by registered users via Resource Link (TM) http://www.ibm.com/servers/resourcelink/ A user's guide for this function is available, and is named Configuration Utility for FCP LUN Access Control User's Guide, publication SC33-8280-00. FCP LUN Access Control will be supported by the FICON Express2 and FICON Express features when configured as CHPID type FCP, will be exclusive to z990 and z890, and is planned to be available in the z/VM and Linux on zSeries environments. Refer to the Software requirements section for further information. This statement represents IBM's current intentions. IBM development plans are subject to change or withdrawal without further notice. To obtain the authorization code for downloading both the configuration tool and the user's manual via Resource Link, contact via e-mail: [EMAIL PROTECTED] You must include your Resource Link ID, the customer name, the z990/z890 machine serial number, and a short description of intended usage.

Redbooks: Domino 6.5, CISCO MDS 9000
* IBM Lotus Domino 6.5 for Linux on zSeries Implementation See: http://www.redbooks.ibm.com/abstracts/sg247021.html This IBM Redbook will help the reader plan for, install, and configure the new IBM Lotus Domino 6.5 product on an IBM zSeries system running Linux. We discuss why you should consider running Domino for Linux on zSeries, and list the advantages of running Linux in a guest under z/VM . We then describe the structure of running Domino for Linux on zSeries for those who are not familiar with all of those products, and review what is new in Domino 6.5, since this is the first release that is supported on Linux on zSeries. We provide detailed technical information about planning, allocating, and managing disk space, network considerations, installing Linux and Domino, and administering Domino. We also discuss systems management, capacity planning and performance tuning, connectivity to DB2 , migration from previous Domino releases or Domino servers on other platforms, and troubleshooting. This redbook is targeted to zSeries systems programmers, Domino administrators, consultants, and service technicians. This updated version includes information from customer and IBM experiences. - * Implementing the Cisco MDS 9000 in an Intermix FCP, FCIP, and FICON Environment See: http://www.redbooks.ibm.com/abstracts/sg246397.html This IBM Redbook describes how to install and configure the Cisco MDS 9000 family in an IBM Fibre Connection (FICON), Fibre Channel Protocol (FCP), and Fibre Channel over IP (FCIP) environment. We have tried to consolidate as much of the critical information as possible while covering procedures and tasks that are likely to be encountered on a daily basis. Each of the products described has much more functionality than we could ever hope to cover in just one redbook. The IBM/Cisco SAN portfolio is rich in quality products that bring a vast amount of technicality and vitality to the SAN world. Their inclusion and selection is based on a thorough understanding of the storage networking environment that positions Cisco and IBM, and therefore its customers and partners, in an ideal position to take advantage by their subsequent deployment. In this redbook we cover the latest announcements related to the IBM/Cisco SAN family. We show how these announcements and the products can be implemented in both a mainframe and an open systems environment. We address some of the key concepts that they bring to the market, and in each case, we give an overview of those functions that are essential to building a robust SAN environment in an effective and concise manner. -- 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

Redpaper on cloning FCP disks
See: http://www.redbooks.ibm.com/redpapers/abstracts/redp3871.html This Redpaper describes a procedure to clone a root filesystem residing on an FCP-attached SCSI disk. Cloning SCSI disks that act as a Linux root filesystem requires special processing (compared to cloning ECKD DASD). An initial ramdisk containing the zfcp device driver is required to IPL from SCSI. The ramdisk also contains the FCP device mapping needed to access the root filesystem on the SCSI disk. When the filesystem is copied, a new initial ramdisk must be created on the cloned disk. This ramdisk must map the cloned SCSI disk as the root filesystem (and not the filesystem on the original master SCSI disk). We illustrate the steps using a SUSE SLES9 Linux distribution running as a guest under z/VM. The procedure also applies to Linux running in an LPAR on zSeries. -- 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

Re: Effect of LIMITSOFT vs NOLIMIT?
If NOLIMIT is set then it's possible for the share leftover when everyone has had their SHARE satisfied can be consumed by a single virtual machine. Using LIMITSOFT means this leftover will be shared according to the value set. Imagine an apple pie. After everyone has had 1 slice and there's some left over, then with NOLIMIT a greedy individual can gobble the whole lot.

Re: 127 device limitation for hipersockets
I'd use a VSWITCH for the small packet traffic. The OSAs would internally switch things between partitions. I'd use real hipersockets for the big packet stuff to directly connect partitions/machines. That way you're not relying on a single machine being up and acting as a router as well as eliminating the router overhead. This way you'd half the real hardware requirements and allow growth until the limit is addressed. -- 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

Re: z/VM Virtual Switch Controller define problem
Somehow the user you are using is a class A user and the first/only one on the system. As such VM has made your user the system operator and your console mode defaults to CP - all commands go straight to CP and not to the operating system within your virtual machine. You need to: 1. Logoff 2. Get the true operator logged on 3. Change the user's configuration to eliminate class A If you really want this situation you can enter TERM MODE VM and CP will pass the input to your virtual machine rather than intercepting them.

Re: ILC for signal handlers
Excellent news. Many thanks Uli. Changing ucontext would cause significant ABI issues, so we like to avoid that if at all possible ;-) In any case, for those signals where the PSW address points after the faulting instruction, the siginfo_t always contains a field si_addr which holds the address of the faulting insn itself. This can be used for purposes like the one you describe. There has been a little bit of confusion about just when the PSW points to or after the current instruction in the past, but the rule (that current 2.6 kernels enforce) is: SIGILL/SIGFPE/SIGTRAP point after the instruction, every other signal points to the instruction. For an example of how to handle your very problem (analysing SIGFPEs resulting from divide), you may have a look at libjava/include/s390-signal.h (HANDLE_DIVIDE_OVERFLOW) residing in current GCC sources. -- 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
ILC for signal handlers
When a signal like SIGSEGV or SIGFPE is intercepted by a signal handler that receives signal no., siginfo_t, and ucontext the PSW is that of the program old PSW. However, the instruction length code (ILC) is not passed anywhere nor can is it accessible (nor could it be relied upon) from low-core. This makes writing signal handlers that inspect the problem difficult. For example, I want to distinguish between a zero divide exception and other fixed point exceptions (both PROG 009). I'd like to inspect the opcode to see if it was a divide operations and then check the operands to see if the divisor was 0. The divide instruction could be 2, 4, or 6 bytes long (RR, RX, RXY format) but because the PSW address is pointing to the instruction following and there's no ILC I cannot write a foolproof method of finding the opcode (having 1d20 could be the opcode for DR but it might be part of the displacement field of the D, DL instructions). I'd like to suggest that the ucontext structure be enhanced to include the ILC information. (Changing the current behavior of the PSW address would probably cause massive breakage.)

Patent Office Rejects Microsoft's FAT Patent
See: http://linuxtoday.com/news/2004093003026NWLL
In the reexamination proceeding initiated earlier this year by the Public Patent
Foundation ('PUBPAT'), the United States Patent and Trademark Office has rejected all
of the claims of Microsoft's patent on the FAT file system, which Microsoft describes
as 'the ubiquitous format used for interchange of media between computers, and, since
the advent of inexpensive, removable flash memory, also between digital devices.'
Relying predominantly on evidence provided by PUBPAT when the reexamination was
requested, the Patent Office made multiple rejections of the Redmond, WA based
software giant's patent. Microsoft has the opportunity to respond to the Patent
Office's rejection, but third party requests for reexamination, like the one filed by
PUBPAT, are successful in having the subject patent either narrowed or completely
revoked roughly 70% of the time...
