managing mixed environments with MobaXterm

connect from Windows clients to Linux servers

MobaXterm Professional provides full X server and SSH support in a portable (no install required) customized (no unwanted games nor tools) application.

connect from Linux servers to Windows clients

Diligent system administrators usually isolate the EPM system servers completely from the Internet, allowing no direct connections. The recommended practice is to download and validate more than 20GB of Oracle EPM source software and patches to a client desktop before transferring to the EPM servers. By running MobaXterm on a Windows client, secure connections, rapid file transfer and remote terminal access is straight-forward from the Windows client to Solaris/Linux servers AND from Solaris/Linux servers to the Windows client.

Prerequisite: MobaXterm Professional
This post describes the process that I use to setup MobaXterm Professional. The cost is negligible as we remove components undesirable in client environments (e.g., games, port scanner, network packet capture, http server, NFS server, et cetera).

In addition, we will add plugins (e.g., httperf, Curl, and DnsUtils like dig or  nslookup).

The Home Edition is free, subject to MobaXterm terms and conditions, but somewhat limited and excludes professional support.

      13. Close the customizer and test the new package by extracting the zip; I used C:\projects\software\MobaXterm\MobaXterm_Portable_epm-jonhwilliams
      14. In addition to the MobaXterm.exe, the folder might contain an automatic backup, configuration files and plugin files, per your selections. MobaXterm configures and starts X at runtime

      15. Starting an SSH server on Windows is a three-click process. This allows a Linux user to connect to a Windows machine and rsync files as needed.

      16. Start, stop and configure SSH Server using the buttons. Use any available port

using rsync and ssh

There are extensive writeups on-line to help with rsync and ssh. Here are the two commands I use most frequently.

First validate that SSH Server (in MobaXterm) is running on the Windows client machine. From the Linux server:

ssh -X WindowsUser@windows.client.where.SoftwareDownloaded

If that works the following will synchronize and validate  all source files in drive L to the Linux hyperion installer drive (dry-run does what you think it should; check out the other options here)

rsync --dry-run -Ivvvrtz -e "ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" --progress WindowsUser@windows.client.where.SoftwareDownloaded:/drives/l/ /u01/hyperion/installer

external links

The rsync utility can really mess things up if you don’t know what you are doing, so take some time get to know what you are doing. The advantage is a rapid, validated file transfer, that if interrupted will resume without complaint wherever transfer got interrupted.

If you need more robust tools for frequent transfers of massive (TB) data, there are other options.
