Re: Getting to a VM/Linux Guest
I don¹t believe this will work. Looking at their web site, they don¹t acknowledge that the product runs on anything but Intel. If they had installs for it on other platforms, any other platforms, you¹d think they¹d be proud enough to say so -- Robert P. Nix Mayo Foundation.~.

For administrative tasks, ssh. For regular user access, that would depend upon the application. In some cases they're web based (Websphere, SAP). In some cases there is a specific client available (Domino). In other cases they're sockets based and the users may or may not know (or care) that they are using Linux on the mainframe (eg.

Re: Getting to a VM/Linux Guest
Once a z/VM Linux guest is defined and the Linux operating system is installed and initial users such as a root user and admin user added to the system what would be the most common way of accessing the Linux guest? Ssh over the network is the accepted method. Could you dial into the Linux guest? No. I've been working on PVM support and LAT support for consoles, but DIAL wasn't on my list. Is TCP/IP'ing to the guest the best way of accessing the guest either locally or remote. Yes. It's the only method that allows full function of the character-mode applications running on Linux.

Re: Getting to a VM/Linux Guest
Note that telnet is not secure. Unless your application or user has a specific need for telnet, TURN IT OFF. Use ssh instead. It provides the same style of access plus a lot more features, and is secure, so your passwords aren¹t flying across the intra / internet as open text. Add to this X11 forwarding, secure intersystem copies (scp), intersystem data tunneling, passing single command lines to the server, and the ability to trade keys to avoid password prompting when performing batch-type routines, and ssh becomes the hammer of choice for system access. -- Robert P.

Linux can most certainly support secure Telnet, whether kerberized, TLS-negotiated, or SSL-wrapped implicit. Granted, no one bothers since they already have SSH, but there's nothing stopping you from doing secure Telnet. Adam
