How to bypass the login banners?

There is actually more than one banner to bypass. One of the them is the message of the day banner, commonly located in /etc/motd. Typically friendly, example in AIX

****************************************************************************
*                                                                          *
*                                                                          *
*  Welcome to AIX Version 6.1!                                             *
*                                                                          *
*                                                                          *
*  Please see the README file in /usr/lpp/bos for information pertinent to *
*  this release of the AIX Operating System.                               *

This is easy to bypass, simply place .hushlogin file on your serverside homedirectory :


$ touch $HOME/.hushlogin
$

Yes, it is that easy.

A bit more cumbersome is the ssh banner. Which rather have an aggressive look with criminal punishment threats.

Well, you could delete it from your ssh server but this would not please your sysadmins. The banner is actually a pre-authentication banner, so you must configure it on the client. With the unix ssh client, you lower the log level. Either with a command line option, -o LogLevel=quiet, or in a configfile

$ cat $HOME/.ssh/config
LogLevel=Quiet
StrictHostKeyChecking=no
NumberOfPasswordPrompts=1

This is so quiet that you will not get any feedback if you cannot connect, but I prefer quiet than noisy.

A very commonly used Windows ssh client is putty, and there, O miracle, there is a pre-authentication-banner option to uncheck in SSH-Auth.

This appeared in putty 0.62 and it made my day today :-)

The new metalink interface

I just started using the New My Oracle Support User Interface

It is a zero-flash interface with more capabilities than the “html” interface we used the previous years. It still provides about the same browser experience as the flash one.

Have a try… according to Oracle : “it will eventually replace the Flash version”
To my French speaking readers : eventually does not mean “√©ventuellement” but rather “√† l’occasion”.
Google Translate is quite ok this time : “elle finira par remplacer la version Flash”

change system wide PATH variable in Windows

This is utterly simple and mostly you did it with the mouse.

To do it with command line and powershell, proceed this way.

Open a powershell window


powershell

or if you have no right to edit the machine-wide environment, runas admin

runas /user:yourdomain\youruserplusadmin powershell

then access the environment assembly


[environment]::setEnvironmentVariable("PATH","c:\oracle\product\11.2.0\client_1\bin;C:\WINDOWS\;C:\WINDOWS\system32;C:\Program Files\Putty;C:\Program Files\Perforce;C:\Program Files\TortoiseSVN\bin;C:\WINDOWS\system32\WindowsPowerShell\v1.0","MACHINE")

MACHINE is a for a Machine-wide setting and USER is for a USER-wide setting.

I hope it will be of some use

Completly unrelated, Enterprise Manager 12c for AIX is out. Do not wait it for HPUX, it is not planned. For Windows 64bit, it will come “between March and May 2012″ according to note 793512.1 on metalink
