RHEL5 won't support TLSv1.1 or higher

Posted 03-19-2016 at 10:59 AM by MensaWater
Updated 03-19-2016 at 09:15 PM by MensaWater

We found the version of curl provided for RHEL5 does not include the flags "--tlsv1.1" or "--tlsv1.2" provided by later versions of curl.

This means CentOS5 curl does not include/support the flags "--tlsv1.1" or "--tlsv1.2".

RHEL7 and RHEL6 versions do support TLSv1.1 and TLSv1.2 and work when using them. One might need to run yum update for curl and/or openssl to have the versions with the support. On my RHEL6 systems I had...

It runs from command line but not from cron or init script

This question has been posted many times over the years both here at LQ and other sites. Accordingly I'm making this a blog post in the hopes people will find it useful.

When one run things at command line they inherit the environment of the user running them as set by things such as /etc/profile, $HOME/.bashrc, $HOME/.profile and/or $HOME/.bash_profile.

There are many environment variables that can impact a script. You can see all the environment variables you...

CLI to get Oracle Supply Network email attachments

Posted 10-06-2015 at 03:37 PM by MensaWater
Updated 11-12-2015 at 08:05 AM by MensaWater

I'm writing this up because I've often seen the question "How do I extract email attachments at command line?". I had to figure out how to use various tools to do this recently and figured I'd share what I did.

EDIT 11-Nov-2015:
While what is written below certainly works for extracting email attachments including those sent by OSN it turns out Oracle does NOT include all fields in the email they send so we ultimately abandoned this setup for OSN and are instead...

Running jnlp on Windows 7 as Administrator

Tags jnlp, san, windows7

OK - This isn't really Linux but is related to work I do as a System Admin wherein we use Cisco DCNM (Fabric Manager) to manage our Cisco MDS 9513 SAN switches. In addition to installing the Fabric Manager jnlp on our local Windows 7 workstations we install the Device Manager jnlp (element-manager.jnlp).

We did a recent upgrade to DCNM 6.2(5a) on our main Fabric Manager server (Windows 2008 R2) and upgraded the switches to 6.2(5) version of NX-OS. (One must run a version of DCNM/Fabric...

Interface reverts to different zone in firewalld RHEL7 (SOLVED)

Posted 06-16-2015 at 02:47 PM by MensaWater
Updated 06-16-2015 at 02:49 PM by MensaWater

We recently setup a couple of new DMZ servers so decided to use zones "internal" and "external" rather than zone "public" (which RHEL7 uses by default). We also set "internal" as the "default" in firewalld.

We used firewall-cmd to assign our em1 interface (this is first embedded NIC, on some systems this might still be eth0 instead) to the external zone. We then assigned em2 (second embedded NIC, this might be eth1 instead)...
