Starting with newer versions of OpenVPN Ibelieve 2.2+ you need to have "script-security 3" set or you can't execute a third party script.
Prior to that you could also use the auth-user-pass-verify like this:

curl: (35) Unknown SSL protocol error in connection
The main solution is to update curl and nss. If you are having an issue with curl through Apache/PHPyou will need to restart PHPafter.
It's important to remember that this error could mean a lot of things but most often it simply means that curl and openssl may be outdated and only allow newer secure ways of connecting to SSL.
In general here is how you would fix it in most c........
Some of the cheaper or newer SSL suppliers will require this to work properly (otherwise you may be prompted that the cert is invalid when it's not the case but it will certainly scare off your users!).
In the Apache vhost conf for the domain here is what you add:
Here is a full example of an SSL Vhost config in Apache using a CA Certificate file
Unable to negotiate with 192.168.1.99 port 22: no matching host key type found. Their offer: ssh-dss
It looks like the DSS option is not considered secure so when connecting from newer Linux systems to an older one you will get the above error.
It can be fixed (but you should consider upgrading your SSH daemon):

Centos 6 requires GLIBC 2.12 however a lot of new programs you would want to compile may need a newer glibc. You can't remove the old glibc since the whole OS is based on it but you can install the updated glibc alongside it and do an export pointing to your updated GLIBC.
mkdir ~/glibc_install; cd ~/glibc_install
pcimodules no longer works it produces nothing probably because the format of /sys/bus/pci is different.
lspci -k doesn't work on older lspci versions.
pciutils can be compiled but it won't work if you have an old system and compile on a newer glibc.
iteriate through /sys/bus/pci/devices/*/modalias
Done on Centos 7.3 very important as clearly based on older guides it was a lot easier and more simpler! Hint do not use grub2-install!
One huge caveat if you are an oldschool user or sysadmin who has avoided UEFIbooting
The normal way will not work here if your Centos was using UEFI. Newer systems use it by default.
The easiest way to check is to do an fdisk -l if your sy........
This is a 8TB Seagate external USB 3.0 device apparently newer kernels use a module called "UAS" instead of "USB Storage" which causes issues as a lot of devices are not properly supported in UAS mode by the kernel driver. The solution some say is to disable UAS specifically for your USB device but I'd rather just disable UAS altogether.

It all comes down to a bug essentially where you are running an older kernel that doesn't support the newer Debian templates. The solution is to update your OpenVZ kernel.
Here are some symptoms of the problem/lack of kernel support:

There was a problem importing one of the Python modules

It seems every other updated version of Java or Icedtea breaks things and I will save the frustration of Java for another post.

In plain English this happens after you upgrade VBOX and it rebuilds kernel modules based on a newer kernel than you are running (eg. you upgraded your kernel but haven't booted into it).
It is too bad there is not a standard work around that would allow it to realize this and keep old kernel modules and use them if it detects your current kernel is older than the most recently build modules.
RTR3InitEx failed with rc=-1912 (rc=-1912)
It sounds like this is corrected in later versions of the OpenVZ kernel but Iam not sure, it may also be that a much newer kernel is needed and Centos may not have a recent enough kernel.
*Debain 7.0 however does work fine as a temporary fix or work around.

Iwas surprised to see that Linux Mint at the latest 17.2 version still has NO mdadm installer option, and worse the installer will not be able to create a proper booting environment even when you do install it.

Are you getting the same old error message even though your iptables settings for OpenVZ are correct?
iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
The reason is because in newer vzctl the old way of setting IPTABLES="" in vz.conf is completely deprecated (I spent some time fiddling wondering why my settings were correct but........

This is because you need the libimobiledevice-utils package installed and a newer version of it.
My older Ubuntu 10.10 uses a version that does not have "idevicepair" which seems to work perfectly and automatically with newer versions of the library.
Basically if you install the above library it should be plug and play and if your imobiledevice-utils doesn't have 'idevice........

I was having an issue with only certain random/jpeg files with the functions imagecreatefromjpeg imagecreatetruecolor and other related ones.
This issue was annoying basically it seems like a libgd issue/bug with newer versions of PHP and it was difficult to trace-out. One very useful thing that helped me was using "php-cgi" and passing the query string as an argument eg:

This may sound silly but there will be conflicts/issues with the default Centos repository so you have to use a third party like remi (I prefer not to do this but it's the only option unless you migrate your sites/data to another server or can stand some downtime-not an option IMHOon a production server).

Have you ever found a website/page that has several or perhaps dozens, hundreds or thousands of files that you need downloaded but don't have the time to manually do it?
wget's recursive function called with -r does that, but also with some quirks to be warned about.

I wanted to Import/Use a .vmdk hard disk image file from VMWare. Generally you can just "point" VirtualBox to it and use it and it will work but I found an exception.
One of my Centos 4.4 x64 images wouldn't boot. I had two copies, an older one and the newer one. The older one booted as normal (once I changed the VirtualBox driver to IDE from SATA). The newer one stopped at the "GRUB loading" message no matter what I tried.

The solution is simple but it's a wonder why VBOX doesn't address it directly?
Perhaps newer versions will but you have to add your user to the "vboxusers" group and then login and logout and you'll see the devices you wanted but couldn't access are now available.
The weird thing is that the grayed out issue doesn't happen with all devcies but one notable thing is the Apple iPhone especially in DFU or Recovery Mode which is an big issue for some people.........

It's not just as simple as running the chroot command, you need to ensure the /proc and /dev entries are passed through and populated to the chroot environment.
Step 1 - Mount Your Off-lineOS

Step 2 - Mount Proc
mount -t proc none /mnt/proc
Step 3 - Mount Dev
Most guides will tell you to use this: mount -o bind /dev /mnt//dev but that doesn't work for some reason in many cases:

*This is a bug with initramfs support, all kernels after around 188.8.131.52 suffer from this problem.
