This service machine would then use VM's LDC (?) to create a 3270 session and it would convert the 3270 control sequences to VT-100 control sequences. Troth writes: Arty Ecock wrote a TNVT100 program for CMS which lets one TELNET from z/VM to, say, Linux. I seem to remember that he said it was a difficult project and that in practice it doesn't work as well as one would hope. Still, I love this thing! It's ... er, uh ... elegant. Now ... the protocol conversion you describe above is going the other way. That's talking about plugging in a byte-at-a-time terminal into a block-mode service. That's the easy way, ala TN3270 and ye olde 7171. Going the other way is the tough trick. (And I know you know it's reverse. I'm just stating that it is harder to do.) But it can be done. In my relative youth, I wrote an application that used remote 3270s (we're talking bi-sync here), using EXCP. Part of the application (ir was really a basic TP monitor) provided the means to use enquiry programs written in COBOL, hiding all the 3270 stuff from the programs. As you might guess, I got fairly close to the protocol as it goes over the wire, along with driving your actual 3270 screens. As part of the project I got to advise the block writing the network software, we didn't have real 3270s, they were async glass teletypes. In ASCII, so I had to handle EBCDIC screens (local and remote, the ones I had to practice with) plus remote ASCII 3270s. The 3270 emulation took a while - basically it's equivalent to writing slushware for the screne itself plus for the controller, but its moderately straightforward. To support 3270 terminals in Linux, we'd need SNA (for SNA terminals) and/or bisync. I don't know how long the SNA would take (or even if its already available), but I guess the bi-sync implementation would be about what I did: not a huge task, and something I could do comfortably in Hercules _iff_ I have a (emulated) 2701 controller. I don't know that Herc does that. The problem is everone's favourite Linux applications. They all expect to see each keypress as it's made. Run lynx, type / and it immediately responds. Ditto vim, emacs, links, mutt, pine. Would you be happy using a 3270 if every second keypress is ENTER? My suggestion: If possible, use a PC running Linux. Use z3270 to talk to VM, zOS etc. Use ssh to talk to zLinux, X if you're comfortable doing that. If not that, then Windows on your peecee, a 3270 emulator and putty. If you're stuck with 3270s, talk about reequipment:-) btw rdesktop does a fine job getting a Windows desktop onto a Linux peecee. I use it regularly. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ do not reply off-list -- 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: protocol converter?
Russ Teubner developed and marketed a product called A-Net that did something very much like this for SNA-attached 3270 terminals. It ran on MVS, VSE, and VM (including VM/370). The emergence of A-Net marked the advent of Teubner Associates, when has since merged with or been acquired by Esker. The SNA requirement on VM required VTAM, which required GCS, which is probably more than you bargained for. And, the remote connection to the ASCII application, if you will, used TCP/IP mostly, but could also connect through a 3708 protocol converter plus a few other connectivity options. So there are a few issues with that specific product or others like it that would not natively address the requirements as I understand them, meaning it would take additional development work to do it. But the nuts and bolts part of performing ASCII terminal emulation for a 3270 device was available in A-Net. Yes, it can be a pain using an application as control-character intensive as vi with ASCII terminal emulation on a 3270 device - but in a significant number of cases, even these types of applications could be made usable with A-Net in a limited environment. Commonly-used key sequences were programmed as scripts that could be invoked by PF keys. So, yes it can be donebut I suggest you consider the specific application(s) you intend to use with such a capability. If these applications are heavily dependent on use of control character sequences, and I consider vi to be in that category, then keep in mind that you have a greatly-restricted number of AID keys on a 3270 keyboard (usually about 30: PA1,2,3, PF1-24, ENTER, CLEAR, maybe ATTN if you can use that) vs. all the keys on an ASCII keyboard that you attempting to emulate. Randy Evans, Viaserv, Inc. I'm curious if something similar could be done for Linux. That is, have the Linux console be defined as CONMODE 3270 in the guest's VM directory. Now, have a device driver which could do a reverse 3270 protocol conversion. That is, make the 3270 appear as a VT-100 (or subset). The application would use VT-100 escape sequences. The device driver would convert these to 3270. I will grant that emulating the full duplex ability of the VT-100 and control keys would make this difficult. But z/OS DIDOCS emulates a full duplex capability on a 3270, so it should be possible.

While 'fdisk' does work, last time I used it there was some confusion in its logic when run against FBA. Note that FBA does not require the low-level format function of 'dasdfmt'. It is already blocked. No shame in using /dev/dasdd as un-partitioned! If it is to be LVM fodder, that makes all the more sense. But if you abso-blasto-lutely must partition it, then CP LINK the EDEV to CMS and FORMAT it there. You'll then automagically get LDL (zLinux disk layout) instead of CDL (compatible disk layout, which requires CKD). CMS FORMAT will skip the block creation on FBA disks and simply lay a CMS filesystem onto the disk.

Since FBA volumes, by definition, don't need formatting, dasdfmt was written to bail if you point it at an FBA device.

Has anyone setup the '/' root filesystem to be multipath-tools and LVM with SLES9 SP3 ? I have setup three SCSI devices. One for /boot, one for the '/' filesystem, and a third one with individual LVM filesystems. /boot is it's own small SCSI device. I have the main '/' filesystem as a separate SCSI multipath/lvm device (/bin , /sbin, /dev, /etc, /mnt, /proc, /root, /srv, /sys, /lib, /lib64) These directories are on another SCSI device multipath-tools device with individual LVM filesystems: (/opt, /home, /usr, /tmp, /var). I get this message during the SCSI IPL: Reading all physical volumes. This may take a while...

Isn't the better/full answer to get IBM to support the Integrated ASCII Console on the HMC? Lee Well, that assumes you have physical access to the HMC. But, yes, I would like that. Or have z/VM emulate the Integrate ASCII Console for the guest systems. I guess what is really needed is a free 3270 full screen editor (like UTS NED) that can be bundled with any Linux distribution. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.

Re: question on '/' root filesystem as zFCP/multipath-tools/LVM
Hi Mark, Yes, we did go thru what we believe is the correct modules for FCP support in the initrd. We ran the mkinitrd after chroot to the new SCSI/LVM/Multipath-tools design. We had changes in lvm.conf, created multipath.conf, changes to udev.rules. mkinitrd and zipl output: Linux0:/ # mkinitrd -d /dev/rootvgx/root Root device:/dev/rootvgx/root (mounted on / as ext3) Module list:jbd ext3 dasd_diag_mod dasd_fba_mod dmsetup dm-multipath dm-mod dm-snapshot dasd_eckd_mod sd_mod zfcp Kernel image: /boot/image-2.6.5-7.252-s390x Initrd image: /boot/initrd-2.6.5-7.252-s390x Shared libs:lib64/ld-2.3.3.so lib64/libacl.so.1.1.0 lib64/libattr.so.1.1.0 lib64/libblkid.so.1.0 lib64/libc.so.6 lib64/libdevmapper.so.1.01 lib64/libdl.so.2 lib64/libpthread.so.0 lib64/librt.so.1 lib64/libselinux.so.1 lib64/libuuid.so.1.2 Cannot determine dependencies of module dasd_diag_mod.
