Re: Read-Only Telnet
You may wish to do what we have done with our application running on all platforms, not just Linux/390. We direct logs files out through a secure port to one or more log servers. The level of detail of this action is set by the system administrator and the log files for the application are reviewed at one or more workstations located in one or more areas. For secured access to the system by the administrator(s), use SSH/Telnet. For log files, see above. This can be done with syslog as well.

The prime example that the developers keep bringing up is along these lines: User A calls in a problem which working with the app via their browser.The developer wants to ssh into the host and issue a tail -f logfile while the user is doing their thing to better understand the sequence of events causing the problem. With the current FTP method, it becomes difficult to completely correlate User Action A with Log message B, especially if their are other folks working just fine at the time. rbash was one of the ones that came up in my searches after your earlier post, but I haven't really had time just yet to delve deeper into just how restricted, restricted is. (Specifically preventing the modifications of files you might otherwise gain access to via world permissions). Generally a shell user is not supposed to be able to harm the system in any way I frankly feel pretty good about the permissions elsewhere on the box, (Famous last words) however given that I have such little control over the permissions within this applications directories, I was hoping there was a safer way. Something that would override any world permissions. In my ideal pipe dream, not only would I be able to see You can look but you can't touch, but I would even be able to deny access to You shouldn't be here ever ever ever types of files. (Although the vendor appears to have done this much right. I should be able to do that with group permissions right now, but it would be a nice thing to be SURE). Mounting the system read-only may work. But remember that some actual work has to be done on this system. That is: those developers need to actually change config files. We have a change management process in place, so if they go in and determine the problem requires a change, they would need to go to the development system, make the changes and promote them as needed, so in this case, the Read-Only image might be a good way of doing what I need to do. On a side note, the security admin suggested that a different way to tackle this might be through key-stroke auditing, we could allow the developers in doing the best we could with permissions as they are and send a report of what EXACTLY they did somewhere that they couldn't get to. That way IF someone did something bad we could at least figure out who/what/where/and when, (why would be a whole different can of worms).. Any suggestions down that road would be appreciated too.

That this has been enshrined on Linux is certainly short sighted. The only reason I use vi is that 1) it is much the same on each *NIX system, 2) and it is reasonably compatible with the ex editor and sed for HMC and 3270 terminals, so I don't have to relearn an editor everytime I change terminal type. Its just as amusing that the 1970's technology of the 80 column card, transfered on the 3270 glass tube was enshrined on MVS as ispf and VM as xedit. Neither of them work very well for long, variable length records such as a long /etc/parmfile line. And its beyond annoying when xedit translates my parmfile to ALL UPPER CASE by default. The case m i command is NOT intuitive. At least ispf prereads the data and sets the mode to something reasonable, but then its pretty bad at dealing with something past 80 bytes. Vi has sense enough to wrap the lines. What really is needed is a simple editor that is a more intuitive and universal, rather than arguing whether the 3270 implementations are better or worse than the teletype implementations. But there are plenty of those! (pico^H^H^H^Hnano and joe are nice two. relatively intuitive). But both will show garbage on a 3270 terminal... Maybe someone could come up with a simple Java editor that will work the same on HMC, 3270, and teletype terminals! Its an editor guys - we shouldn't have to read a 3 inch manual to make it work! No. most unix text editors use termcap/terminfo to get information about the capabilities of the terminal . Most of them use the library ncurses for terminal graphics, some use slang. I saw that there is a terminfo entry of ibm327x . When I tried to use it pico (sorry, that is the only ncurses program I have at my disposal at tha machine) blantly refused: 'ibm327x': I need something more specific. I tried some other 'ibm*' entries, all of them were accepted, but I got all sorts of different garbages: the escape sequeces were clearly not interpreted by the terminal. Is there any way to get proper termcap/terminfo entries working? (e.g: avoid the need for unalias ls?)

We have an opportunity to put forward a Samba on Linux/390 solution for our corporate file/print needs. The current environment is Novell Netware on 4 X Intel servers, approx 750 desktops, approx 3 million files using about 1TB disk. Our management is open to a Linux on mainframe solution but I don't want to put up a technical solution if it is not robust and scalable. Robust is no problem -- Samba is very, very stable and function-rich. Scalable will take some thought, and require some more information, mostly related to how you plan to deploy it. We are running OS/390 on a 9672-R36 (G5), OSA-2 fast ethernet. One thing: do NOT use the Samba on OS/390. It is *very* old and has known vulnerabilities, as well as not performing all that well. Some questions: 1) Do you have VM? If not, I'd recommend acquiring z/VM before you seriously contemplate Linux-based services. Linux in a LPAR works, but managing it for HA services is a serious pain, and you'll want at least a warm failover server in case you need to do maintenance. Two LPARs is a bit expensive for just fileserver traffic. 2) What is the ratio of reads to writes? Volume of transactions is important; if your existing 4 servers are relatively busy, you probably will need another OSA card or a faster card to avoid degrading performance for the OS/390 system. You may want to investigate alternatives to the OSA with better price/performance curves. 3) Are the current servers colocated, or distributed? SMB and SMB over IP are fairly bandwidth intensive, and IPX over IP is *very* chatty. This will have an significant impact on your WAN if the servers are not colocated today. 4) Do you already have a mainframe hosted backup solution such as FDR or TSM? If not, can you afford to dedicate a tape drive to the LPAR? 5) Are there long-distance WAN links involved in this setup? If so, you may want to consider a more sophisticated architecture such as Samba overlaying a larger scale enterprise file system like AFS. This will substantially increase the scalability of the solution, at the price of some additional complexity (and also offer some nice benefits in terms of bandwidth optimization and backup solutions). If you're interesting in details of this solution, drop me a note off-list. Is Samba going to work well in a real-life production environment? Any thoughts or comments would be much appreciated. Yes, without question, Samba is stable and reliable. The environment around it needs planning carefully, but it's an excellent solution for file and print service. -- db

Re: Informal Survey
Here are my reasons: 1. Across-the-board compatibility for middleware components without compromising the power of the mainframe. This is something we didn't get with OS2, RS-6000/AIX or OMVS. 2. Uniformity. 3. Eliminates OSF/SUN/Unix confusion (finally!). My 2 cents.

Re: WebSphere 4
Yes. 1. When installing DB2 don't use the examples. Use common sense and make sure you read the instructions carefully. 2. Make sure the installation medium you use is consistent with you operating system. Watch for mistakes in upper and lower case. 3. Make sure the installation has an X-Windows environment. I used VNC and it saved the day. You do not need KDE or Gnome. 4. Call IBM Support. These guys are the best. If you have any questions about any aspect of this, call me or write me. I think that WebSphere on L390 is great. I'll let you know if it is better than Apache/Tomcat next. Thanks, Stephen J.
