Bypassing Java with the SGD PC Client

SGD and the problem with Java



Ever since numerous Java exploitations were revealed and fixes implemented in 2013, Java and it's associated security fixes have been in a seemingly constant conflict with another of Oracle's products the Secure Global Desktop (SGD). It seems like each new Java update breaks one or more releases of SGD, forcing either an update of SGD or a difficult down grade to Java. And somewhat similar to being on any other version of Windows than Windows 10, if you're on an older version of Java your system will either constantly harass or silently force you to upgrade.



Fortunately, with newer releases of SGD you have the ability to completely take Java out of the equation by using the "Secure Global Desktop Client" which can be downloaded by connecting to any Secure Global Desktop's initial webtop session. To access the download use your browser to connect to the initial webtop session of your SGD server (in my case that would be https://r2lnx5.rtwotech.com) and look at the initial list of options it gives. Here is the list from my newer instance:

Disaster Recovery of an SXe Database Server







A big worry of any company that relies on a single database server to keep their business up and running is what happens in a worst case scenario when that one single point of failure, the database server, goes down. Typically, unless you have a backup system loaded, running and ready to go, a failure of this magnitude can take days to weeks to resolve (depending on what failed, how fast you can get replacement hardware and how good your backups are).



Some of the factors that contribute to how long it will take to get back up and running are just out of your control. You can’t pre-determine what components will fail, and in many cases, you can’t control how long it will take your hardware vendor to fix the problem, or provide you with replacement parts or a new machine. But there are somethings you can do to mitigate the issue and change that down time from perhaps days to instead a couple of hours or less.

Restoring your Nxt or Nxtwi database into Test



!! Although updating the Test Database from the Live Production DB (if done correctly) should have no effect on Live whatsoever, caution should always be the prime concern. So as descriptive as I’ll try to be here, if you have to do this and you aren’t “completely” comfortable with the procedure, then it would be best to just call/email me and have me (or someone else that knows this process) do it for you…!!



I get a lot of questions and have spent a lot of time restoring customers Nxt and Nxtwi databases into their respective test databases. That being the case, I thought this would be a good place to start the SXe forum for my many Infor customers.

Conventionally Infor keeps the nxt and nxtwi databases in /db, their bi files in /db, their ai files in /ai, the online backups in /backup, the main source, executables, libraries and script files under /rd, and the entire Test structure under /test. So although this is different in some cases we’ll use this default directory structure at the template for our example.

Securing vsftpd in RedHat Linux

FTP (File Transfer Protocol) is a common mechanism for moving files between computer systems. It’s been around since 1980 and has been used so frequently that most computer users have a least some familiarity with its commands and its control structure. The problem is that in its basic and most often found form, it has no security whatsoever. All user logins, passwords and data are passed across the network in a completely unencrypted, open text format. In fact, the vast majority of infected Linux systems I’ve worked on have been infected by users or bots connecting in via ftp.

So what I’ll do here is show you how to secure your vsftpd site by modifying the vsftp.conf configuration file and adding a self-signed certificate created with Open SSL.
