Re: How to enter control characters from an EBCDIC keyboard?
I use the carrot ^ (above the number 6) followed by a capital C: ^C for Ctrl-c on the 3270 console. -Original Message- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of Clovis Pereira Sent: Sunday, April 04, 2010 4:27 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: How to enter control characters from an EBCDIC keyboard? Hi, Sometimes, I forgot to type the cont parameter using the ping command on a 3215 terminal (example: ping -c 4 ip.address). In 3215 terminals, ping without a count result in a forever command. The unique way to stop it (al least the unique I know, without terminate the session) is a Ctrl-C. In this case, I open a Notepad session, click a Ctrl-C pair (^C), paste and copy it in the 3215 session, so stoping the ping command. Obviously, I use it on a PC and using a 3270 emulator that supports copy/paste. I think a Notepad session and copy/past can be useful. Regards, Clovis.

Sent by: Linux on 390 Port LINUX-390@vm.marist.edu David Boyes wrote: I'm working on EBCDIC support for Perl 5. I'm not familiar with EBCDIC terminals, but apparently there are asynchronous ones. Very, VERY rare -- to the point of almost non-existent. The 3270 is the primary terminal type, and it's half-duplex, page-oriented. The older line-mode terminal (the 3215) is emulated, and pretty much behaves as a dumb TTY. How can one enter a control character from such a terminal? On ASCII terminals, pressing the Ctrl key and another at the same time generates a control sequence. Since H is the eighth letter of the alphabet, CTRL-H sends 8, which is a backspace on ASCII platforms. Is there something similar that happens on EBCDIC? The convention to enter a control character is to use the digraph '^letter' (EBCDIC not or cent sign (depending on code page) + character) and have apps translate that to the appropriate code point. The issue is that control characters in a 3270 world don't work the way they do on byte-oriented terminals, so they're rare (if not almost non-existent) in the 3270 environment. In the rare event a control character is used, it's almost always represented as a hex value in a string (for example to enable color or highlighting), and those don't occur as control characters. I don't understand the above. On ASCII terminals, often a control is printed as '^letter.', but entering requires pressing two keys at the same time. It seems like you are saying that the terminal will send a control character whenever a not or cent or maybe caret is typed whenever followed by a letter. If so, how then does one enter these three characters literally? And where could I find a mapping to look at, a sample for one of the code pages? The few EBCDIC code pages that I'm familiar with have 65 controls: 0 to 0x1F plus 0xFF. Are all 65 enterable from the keyboard? See above. I see from the archives that there are some problems between the ASCII LF (or NL) and the EBCDIC NEL. Is there a rule of thumb for which of these, or both, should mean a new-line, matching, say, '\n' in the C language? On a page-oriented terminal, the concept is somewhat difficult to represent. Writing a newline doesn't actually update the screen until you rewrite the page. On the older terminals (3215), the equivalent would be processing a CR/LF pair. In fact, you pretty much need to assume that all line-oriented I/O has exactly the function of a TTY. No cursor positioning, nothing smarter than a TTY. Also, in looking at the Perl 5 source code, it is clear to me that no one is running modern Perl versions on EBCDIC platforms, because it wouldn't work. But I can't imagine a Linux system without Perl. Could someone explain? Linux on z is an ASCII system. Perl works just like it does elsewhere. Ditto with OpenSolaris for Z. There isn't anything in the Z hardware that dictates the use of particular character sets; it's just what you program it to recognize as character graph 'A'. IBM has included machine instructions to help process EBCDIC data, but that's for the convenience of OSes who choose to code data that way. I guess I would ask what kind of EBCDIC support are you creating? Other than providing a string translation function (to_ascii, or to_ebcdic), I'm not sure what EBCDIC support for Perl would mean. Perl already has a codepage mapping toolset, and there are a number of EBCDIC variations, so the question of which EBCDIC? comes up. Are you porting Perl to a specific IBM OS? If so, that might be a very different set of questions. -- db -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit

Multipathing in failover mode question
Hi, We are running kernel 2.6.18-128.el5 (Red Hat 5) with device-mapper-multipath-0.4.7-23.el5 in failover mode. Two paths are defined to each LUN in zfcp.conf. I expected the first path defined to be the primary and the second path to be the failover path. That is sda to be the primary (active) and sdb to be the failover (enabled).

Re: Size of Linux DASD under Z/VM?
Hi, We run Red Hat 5.3. Our production LPARs use FCP attached SCSI for local file systems, SCSI managed via EDEVs for the OS install (/ and /boot) and 3390's for VM. It takes a lot of planning up front for the SCSI box configuration. 50G and 100G are good LUN sizes. Good I/O performance requires that there be isolation in the backend real drives for groups of LUNs. For example, real drives backing up db2data LUNs should be separate from other file system LUNs. Get lots of real disks. We use multipathing in failover mode as performance is better than multibus mode. We also use the data=writeback option on the mount command. Also use LVM striping.

Nfs and pcnfsd daemon
Hi, On a Linux 2.6 kernel (I'm using RHEL 5), how is the pcnfsd daemon started? I have an SFS fiespace mounted via NFS on a zLinux guest and cannot write to it.

Re: Nfs and pcnfsd daemon

Betsie -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of David Boyes Sent: Thursday, April 10, 2008 11:37 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: Nfs and pcnfsd daemon You don't run pcnfsd on the client; pcnfsd has to run on the server side. It's a hack to allow non-Unix systems to authenticate a connection from a non-Unix system and get a valid numeric UID so that NFS security works. One of the major defects of the NFS protocol: Unix NFS daemons inexplicably believe whatever the client tells them. Except for secure NFS, in which the tokens were just more complicated; it still believed anything you told it; the questions were just harder to understand...8-). The default behavior these days (ignore UID=0 requests unless deliberately stupidly configured) is at least somewhat improved. NFS v4 just uses GSSAPI and defaults to Kerberos 5 authentication. Much better, if considerably more complex to configure. As I said, NFS is a crummy protocol design. DNRFS on DECnet was a lot smarter, as was Courier on XNS. But, it was lightweight and fit well in EPROMs and didn't require licensing ... You need to get the mountpw command (source is provided by IBM) and run it prior to trying to mount the filesystem on the Linux guest. Mountpw allows you to supply a VM userid and pw to authenticate the client, which will then use the authentication token created by mountpw when the actual mount request comes in. Gaaack. Are you saying that Linux doesn't support PCNFS as a client? Well, pcnfsd was invented as a DOS thing -- DOS couldn't do the RPCs necessary to support NFS and didn't have any concept of user anyway. Linux has always had a full NFS client, so usually pcnfs isn't ever needed. I can't say categorically that a pcnfsd client for Linux *doesn't* exist, but I've never seen one. BTW: the URL I referenced is the IBM CMS NFS support page. If mountpw is no longer required, probably time to update it. In your Copious Free Time, that is... or make Miguel do it.

Re: zFCP Disk
Hi Jerry, I am attempting a similar project. I'm trying to use an EMC DMX SCSI box attached to my zLinux guests. I attach (or DEDICATE) an FCP subchannel (an IODEVICE) to a zLinux guest for each physical path I want. We are not going thru a fabric switch but using point to point cabling. (I can't use any of the discovery tools.) I was able to get multipathing working, I believe, using DM-MPIO. My challenge is getting LVM2 working in a multipath environment.

The FCP Redbooks and NPIV Redbooks make some sign cant assumptions on the level of knowledge that we have. So for example: I'm attaching to a EMC Clarion in my test environment. I had to sign into the switch before they could finish the masking, but when using yast it insisted on knowing ALL the details of the FCP connection before I could proceed. By experimentation I found that if I used the zfcp_host_configure command to set the VM device on line it signed me in and out of the switch. Then there was more time spent trying to find commands to show what I could see and where they were all located. Some of the things I came across like san_disc showed up but with no examples to go by I couldn't work out what it was asking for or the appropriate entries.

Single user mode and root password
Hi All, In the virtualization cookbooks for RHEL 4 and 5, it says in single user mode, you are logged in as the root user and all of the file systems in /etc/fstab are mounted. This has not been my experience and I am trying to determine why. None of my SLES 9 or RHEL AS 4 systems go into single user mode without prompting for the root password. I have verified that the TERMINAL LINEND character is set when issuing the VI VMSG response. I have been told that the prompt indicates an error in /etc/fstab or a startup problem. If I boot into another state ( 3 or 5 ), there is no indication of /etc/fstab problems. Checking dmesg, I can't see any errors. Any other suggestions for debugging this problem, please?

I'm currently involved in a discussion about how the usability aspect of Linux on the mainframe can be improved. For this reason I'd very much like to hear about your experience with installing, configuring and running Linux on System z. What has been your most annoying experience in this context? The two areas that get the most blowback from the people we deal with are: 1) The contortions necessary to get the first guest installed, particularly for a traditional mainframe population. Having to use non-mainframe tools or obscure devices such as the HMC CD or DVD drive (which are usually not physically accessible, or not managed by operator automation in a way that is convenient to people doing the installs). We (SNA) are well advanced on doing something about that, but that's the biggest complaint we hear. 2) The difficulty of working with the console in environments with security regimins which require root logins to be limited to the console device for Linux systems. Most sites with Unix or Linux/Intel backgrounds and any concern for security have security standards for managing privileged access to systems. Complying with those standards -- to play along with the message of Linux is Linux -- means disabling root logins on all terminals but the console...but that puts Unix admins in the position of having no fullscreen access to do repairs, and the current generation has no experience with TTY consoles. The VT220 hardware console support is nice, but few have it yet, and won't be available widely until 5.3 becomes ubiquitous (and there's no direct support in the VM TCP stack for a solicitor to connect to a virtualized console). It would also be helpful to know what system you worked with before Linux on the mainframe (e.g. zOS/zVSE/zVM/Unix/Windows/Intel based systems). Everything.

I started with SLES7 on z/VM 4.2 on a MP3000 H30. Now up to SLES9 on z/VM 5.2 on a z/890 plus an IFL. The initial, first, worst fight I had, had to do with installing from some media, on some other foreign (foreign to me, being a VM and VSE type for 30+ years). I first used Win/98 and mounted CDs there. I think I was using Samba. Eventually, I got the networking issues straight and I could install SLES7, which I did over an over (practice makes perfect and I was trying out different machine configurations). This was on a 10 mb LAN. 3-4 hours and it was done (I would be doing other work during this time.) A year passed. Time for some more images. SLES8 was now available. However, I was now on Win/2000. Samba didn't work so well. Many days of fighting this. Finally went to the FTP route. Got a freebie FTP server, and had many trials and tribulations in using it. Networking isn't my knowledge base. And SLES8 had different install options and features. Some nice, some good, but it all looked different. It took a lot of time to realize that I did know what I was doing. However, it still took me a long time to give up on the Samba option and go to a FTP server. Another couple years passed. SLES9 was now available. FTP didn't seem to work anymore. I never figured out what the problem was. But I could still install SLES8. So I created a FTP server from SLES8 to store the SLES9 images on. SLES9 didn't seem to install much differently then SLES8, and it was much faster (no vswitch at that time, just routed thru VM's TCPIP stack). We need something, that can take a dummy like myself and drop down a Linux image, preconfigured and preloaded with the Linux images so a person can do the install from a fast, reliable place. And then documentation on how to install a Linux image, based on this preconfigured/preloaded server. Plus, documentation on how to upload new Service Packs and new releases to this server. About as close to free beer as you can get, without actually having a beer G. Some of the many problems I hit, besides changing PC platforms: Some PC based software didn't understand the long file format of Linux. I think that was mostly on Win/98. I don't know if there is any PCs now that have that type of problem. The default FTP server in SLES8 is configured not to allow you to use that FTP server as a source for a SLES install. You have to know you need to change the FTP config file to allow this. My notes are: Joe /etc/vsftpd.conf Uncomment: Local_enable = yes Write_enable = yes Save Chroot_local_user=yes Required for ftp server for zLinux install During installation, when entered *s390x/sles9root*, it gets translated to */s390x/sles9root*. For install to work, it must remain in the suse9 subdirectory and not changed to be off of root. All the Redbooks on installing zLinux, assume that the servers you are using to install from, are properly setup. Well, this dummy, in which my FTP server experience was limited to the VM FTP server and the default configuration for the CSI FTP server on VSE, there was a lot of knowledge that had to be gained for a Linux FTP server, in order to make it useful. So I was in a Catch-22. My knowledge wasn't sufficient on FTP servers to configure one properly. However, to have a FTP server running to test with, I needed a FTP server to be running. Many times, I put it down and went to other projects for a few months. Then, comes firewalls. From my PC, I can basically do anything I need to. But not from the mainframe. YOU (Yast Online Update), just isn't going to work. The network guys are Windows oriented. They also have very major concerns about viruses. Rightly so, as when a virus hits our PC network (4,000 PCs in a City Wide WAN), it takes months to fix the problems. For access outside of the firewall, they want antivirus software installed. Which we don't have. What I keep thinking of, is some Windows based software, that can pull all the new fixes from Novell, and send them up to a mirror residing on zLinux for distirbution via YOU to my zLinux images. Doable...yes. Do I have time? No. It would be nice to have a drop in solution. And yes, we do have a Novell maintenance contract (and we had a SUSE one prior to that). Next topic: TAPE DRIVES Damn it. We are mainframe. We have Ficon and Escon attached tape drives. They may be behind a VTS. They may be managed by a robotic unit. They may be electronic or disk based. We have existing tape management systems. Try supporting them.

First, I'd like to say thanks for all of the great ideas/suggestions, and second, I'd like to apologize for not responding sooner. Also, just so everyone knows - I am working with a SLES9 SP3 based server. So, what I have figured out at this point is that I definitely did not make the LVM persistent via updating zipl.conf doing a mkinitrd zipl, and since I hadn't IPLed the server since creating the LVM, it was just waiting to get me - I guess I assumed to much from Yast as that is what I used to create the LVM. At this point I have been working with the cippled server to see what I could figure out then accomplish based on everyone's feedback and so haven't taken the recovery system route yet ... Here's what I have been able to do so far: After bringing the 2 volumes online (chccwdev) and re-establishing the LVM (vgchange) and then mounting it (mount /pathname), it looks like I'm back to were I was before - the directories data appear to be intact within the LVM space as well. So I think all I have to do at this point is to update the zipl.conf (by adding 'dasd=100-104' to the parameters statement under the [IPL] section) and do a mkinitrd zipl - does this sound about right? If so, I was wondering if there is a way to update the zipl.conf from a VM-based display since I don't have IP connectivity to the server at this point to use putty and the like - or is this why I need to run a recovery system and chroot into the problem server environment - so I can make this update issue the mkinitrd zipl commands? If I can use the VI line editor to accomplish this from the VM display, for example, does someone know how to do this (what commands will work)? I am going to start working on the recovery system concept - I think it's a good idea in general - even if it turns out that I don't need it for this.

Among other things, the team is responsible for helping customers set up proofs of concept, answering technical questions, giving presentations, writing white papers (and perhaps Redbooks!) and working with product development to ensure they know what customers need. Since I've been very involved with this mailing list, the linuxvm.org web site, SHARE, and Slack/390, one of my concerns was that I be able to continue with all of these. I've been assured by my manager-to-be that I may do so. I'll definitely be at SHARE in Tampa next month. I hope to see the usual suspects from the mailing list there as well. As everyone here knows, while SLES is a good Linux distribution, Novell still has room for improvement in their mainframe platform. The good people at SUSE Labs have told me they would like to work very closely with us, so I hope to be able to act as a conduit between this mailing list, and our customers in general, to help accomplish that improvement. I can't promise specific results of course, but everyone I've talked to is very interested in making SLES on the mainframe even better. I've already got a list started, based on traffic from the mailing list. If you'd like to add something to the wish list, please contact me off-list.

Or just try the FTP again while watching vmstat 10 100 (every 10 seconds for 100 occurrances). Be careful though that your ad-hoc instrumentation is not going to cause load itself. Unless you validated the cost of it, you can not be sure you're not causing it to swap for example. If you just care about swapping: when you swap to VDISK the I/O rate to VDISK for that virtual machine is reported by the monitor, so you can tell what the swap rate was without looking inside... But quite often you also want to see other things (e.g. CPU usage, network traffic, fragmentation, etc). That's why we consolidate Linux measurements in a performance database for review and reporting. And the neat thing is that I can go and look at what happened during the test, without having to set up my instrumentation and run the test again.

Re: HLASM on zLinux install
I could read the headers and trailers of each of the sections but not the PDFs themselves. When I found the trailer for the rpm file, I just backed it up and gave the tape to zLinux and dded the rpm. Since then I've been told by a couple of people to look at the Dignus Systems/ASM product for zTPF builds. The README file from IBM (when I finally received it) had JCL samples for IBGENER.

That is, the image name can be prefixed by the server (CPC) name followed by a dash. This doesn't work so well when the LPAR name contains a dash, eh? :-) So, snipl sees CCPUC-LX2 and assumes it is image LX2 on server CCPUC, overriding the associated server obtained from the config file (I think). So try something along the lines of P0012345-CCPUC-LX2. The Right People have been found (from the source code, I might add!) and notified.
