The easiest way to answer this kind of question is to draw it on a piece of paper. Linux on a vswitch can certainly point to a z/VM static VIPA as long as the VIPA is in the same subnet as the Linux guests. (A gateway is, by definition, in the same subnet as the host.) So if I drew this on paper, the Linux guests would be sending their traffic to VM TCP/IP. That means they are routing. THAT means they get ZERO benefit from the vswitch. Remember that getting rid of the virtual router is the prime reason for using the vswitch in the first place. I don't your statement that you cannot use the same subnet for your Linux guests "without redesigning [your] whole OSA and OSPF network". The Linux guests will have the same requirements as VM TCP/IP. You treat them as you would a shared OSA configuration. Perhaps your subnet is simply too small? If it cannot be expanded, then you can use VLANs to create additional LAN segments and subnets, but you do it inside the switch/router, not inside the mainframe. (Which is where dynamic routing should be done, anyway, IMO.)

Plus, there's simply no benefit to using a journaled file system in read-only mode. The journal is there to record updates that haven't been written out to the file system yet.

Re: vswitch gateway
If you're talking about sending all your Linux/390 network traffic through the z/VM TCP/IP stack, then there's no point at all in using VSWITCH. Simply set up a Guest LAN and define the z/VM TCP/IP IP address on the Guest LAN as the default gateway. You'll need to have z/VM advertise the routes to the IP addresses on the Guest LAN to the rest of the network, but then I take it you already understand that. I'd be really interested in hearing why you cannot put additional IP addresses on the same subnet without redesigning everything. That sounds kind of odd to me, and I'm not even a networking guy.

Re: ftp question, not really Linux
Can the box/PC from which you're ssh-ing to zLinux also connect to the Winx box on which you want to put the file? If so, and if the zLinux ssh server has port-forwarding enabled, you can port-forward (tunnel) SMB thru your PC's shh client to connect your mainframe Linux to your Winx share. You then could use smbclient, for instance, to put files from zLinux onto your Winx share. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of McKown, John Sent: Wednesday, December 29, 2004 12:53 PM To: LINUX-390@VM.MARIST.EDU Subject: ftp question, not really Linux I hope ya'll don't mind.

Re: ftp question, not really Linux
John: Looks like you rolled out an FTP client in C. I have done something similar using Perl (Net::FTP module). It is slick in that you can examine the FTP log in real-time and determine if the FTP succeeded. One of the problem I had was to make sure that the file is processed at the other end only after the transfer was completed. I am not sure if the pipe addresses that issue. In my case, I created a file with the name .in.progress and renamed it after successful completion. __ Ranga Nathan / CSG Systems Programmer - Specialist; Technical Services; BAX Global Inc.

Re: Moving root to a new volume
Hi, Yes, but In my example, I was making the old and new root disks available to a second system. In a follow-on note to mine, Mark Post gave an example of doing it all on one system. I suggest that you look at his method first. From Mark's Post Taking the system out of service for such a long period of time can easily be avoided by: 1. Adding the new disk to the existing system dynamically 2. Doing the same dasdmft, fdasd and mke2fs. 3. Following the HOWTO at http://linuxvm.org/Info/HOWTOs/movefs.html from steps 3 to 4, but doing the "cd" to /, instead of /usr. 4. chroot to /mnt 5. Update /etc/zipl.conf, but only if any device numbers will change. 6. Run zipl 7. exit the chroot environment 8. Unmount the new file system. 9. Reboot at the time of your choice. This also eliminates the need to modify all the other parameters in /etc/zipl.conf to remove the /mnt from the directory paths.

Well, you've just pointed out why this is crazy. If you want to automate it, save the file first, and then wrap an ftp session in expect or something so you can manage the error handling. Or failing that, write a Perl or Python app, using one of those languages' FTP libraries, which takes input on stdin and puts it onto the other box, so you can at least get some sort of failure notification. You could use mkfifo (not mknod) to create a named pipe to feed the input of the script, too, if you wanted, so from your perspective you'd still just open and write a file, but you'd get some sort of error handling. Allow me also to go on my usual rant. FTP is evil. Not only does it transmit authentication information in cleartext, but the awful design of active-mode FTP constitutes a layer 2/layer 3 violation which makes it inordinately difficult to proxy or tunnel through NAT. Yes, I realize that it's what your Windows guys support; that doesn't make it a better idea. It's been time for FTP to die for a decade now.

If you can control what FTP client is used on your system, check out using 'ncftp' and 'ncftpbatch'. ncftpbatch allows you to essentially schedule the transfer as a background task, and there are options to remove files after a successful transfer. This works pretty generically, and the background part is really slick.

The Windows people don't understand, trust, or want anything to do with Linux. The Windows people will trust ftp from us mainframers because they feel that they have greater control. In addition, the ftp is working now, so "why change?" True enough. This is one of my "wild hare" (since I no longer have much hair) type projects. In addition, if I can get this working, I don't need to interface with them at all. They are not very "open". I can understand that. I feel similiarly towards my systems as well. Also, I could do something similiar on our z/OS system if I get it working on Linux (where I feel it will be easier to program and test).

I fork() ftp, with the stdin associated with one of the pipe() file descriptors and stdout/stderr associated with the other pipe() file descriptor. I then feed the appropriate ftp commands to the ftp process via the pipe. Basically, I feed in the userid and password, followed by a "put". The "put" command references the filesystem name which is socket that I did the mknod() and open() on. I feed my report out this. This places my report "directly" on the Windows server. Is this crazy? I do understand the possible problems if an error occurs in the ftp process. I won't have my report anywhere else to send later. In this case, I guess that I would "restart" my report generator to create an actual disk file on the Linux box. It's a low traffic season.

Re: Problem solving z/VM and Linux
Hi Arjen, I didn't see a response to your question about where VM messages are logged. As a general rule, most sites direct all important system messages to the system operator (named OPERATOR unless you've changed it in your parms file). From your question, I'll assume you are not running the Programmable Operator Facility (PROP) or CA's VM:Operator, so there are no 'formatted logs' per se. OPERATOR should be spooling it's console, if not put the following in it's PROFILE EXEC: 'CP SPOOL CONSOLE START TO * CLASS T' To spool consoles to the OPERATOR reader in CLASS T (modify as you may like). Rerun the profile exec. Don't forget to close these console files periodically as they can get quite large. To close a console, execute CP SPOOL CONSOLE CLOSE on the OPERATOR userid (optionally provide TO where-you'd-like-it to close the file to a destination other than OPERATOR's reader, where you initially spooled it to). You can either PEEK at console files in the reader or receive the file to disk (giving it a name since these are 'unnamed' files) and XEDIT it. If you PEEK, don't forget to either permanently change the (dumb!) default of peeking at only the first 200 lines of a reader file by executing: DEFAULTS SET PEEK FROM 1 FOR * Or provide '(FOR *' on the PEEK command. Hint: Use the ALL Xedit command to restrict what you are seeing to records that match your interest, for example 'ALL /TCPIP/' to show records with the string 'TCPIP' in it, ignoring all others.

At our site we've got z/VM Linux guests which sometimes drops it's TCP IP connections. The TCPIP stack off the VM installation itself seems working well! Now I want to browse loggin information etc. to find a clue for this problem. I expect VM to create loggings (at least console) Has anyone an idea where and how to start browsing in VM logs?

Re: Error on startup
You are in a limited shell. You don't have the full set of commands but enough to troubleshoot disk errors. Typically running fsck on the root disk will fix your problems. After you do that, do a CTRL-D.

vswitch gateway
We are setting up a vswitch and our problem is we can't use the same OSA subnet for the vswitch IP addresses without redesigning our whole OSA and OSPF network. My question is 'Can Linux on a vswitch point to a zVM static VIPA as its gateway instead of a LAN router gateway to reach the network?' That way we could maintain our current OSA subnet and OSPF as is. Dave Kutz Network Engineering Highmark, Inc.

Re: File system full
Thanks everyone... There where a number of suggestion that worked very well. It turned out to be a hidden file from a background task that I didn't know the customer had running.
