On Centos, I ran into the following error:
sudo snmptrap -v 2c -c read localhost '' UPS-MIB::upsTraps
MIB search path: /root/.snmp/mibs:/usr/share/snmp/mibs
Cannot find module (UPS-MIB): At line 0 in (none)
UPS-MIB::upsTraps: Unknown Object Identifier
The above error happened after
Copied UPS-MIB.txt to /usr/share/snmp/mibs
I started snmptrapd:
snmptrapd -f -Lo -Dread-config -m ALL
The version of the Net-SNMP is 5.2.x.
The same procedures work fine with Ubuntu 18.04/Net-SNMP 5.3.7.
I wonder how to debug and fix the problem?
Besides the Net-SNMP version difference, on Ubuntu, I found an instruction to install mib-download-tool, and execute it after the installation of Net-SNMP, and comment out the lines beginning with min: in snmp.conf in order to fix the error of missing MIB's.
However, for the Centos, I had no need and found no such instruction, thus I have not done it yet, as there is no error message of missing MIB's.
The MIB file is downloaded from https://tools.ietf.org/rfc/rfc1628.txt
renamed to UPS-MIB.txt (It seems to me that the name of the MIB file does not matter, as long as it's unique? I tried to use a different names, upsMIB.txt, rfc1628.txt, but it does not help to improve.)
I solved the problem as follows:
manually copied /usr/share/snmp/mibs/ietf/UPS-MIB on an Ubuntu with Net-SNMP 5.7.3 installed to the Centos /usr/share/snmp/mibs/UPS-MIB
then restart the snmpd
by the command:
service snmpd restart
then the OID of UPS-MIB becomes visible and accessible.
Maybe, the version that I downloaded from https://tools.ietf.org/rfc/rfc1628.txt is not suitable??
I am getting below error

mcrypt is removed from php7.2. can not use in PHP 7.2. i have created new function and added in common helper.
if (!function_exists('mcrypt_create_iv')) {

}
might be helpful to other users.
install mcrypt
sudo apt-get install php7.2-mcrypt
sudo systemctl restart nginx.service
This polyfill is useful for backwards compatibility w/ mcrypt on PHP 7.3:

I'm running into a fatal error when I'm trying to import using Mongodb 3.3.9. My script has worked before, but when I upgraded my Mac os to Sierra, I'm running into what looks like a Go language problem.

Others have noted a similar problem that was supposed to be resolved in an earlier version (mongorestore random crash (fatal error)), but my problem persists.
As the comments suggested, it's solved reinstalling mongo. If you install it using brew execute: brew uninstall mongo.
If you just followed the steps in their tutorial, just delete the executable. If you don't know how, follow this:
which mongo
#now you have a path
rm -rf yourMongoPath
sudo launchctl unload /System/Library/LaunchDaemons/org.ntp.ntpd.plist
worked for me
I've installed Capistrano on my Ubuntu with the following commands
sudo gem install capistrano
sudo gem install railsless-deploy # I want to deploy a PHP website
sudo gem install capistrano-ext
When I run "capify ." in my deployment folder, have got an error:

I'm a noob with Capistrano and Ruby
Any idea to resolve this problem ?
Thx
Probably what's going on is that you installed Capistrano as the root user. However, running capify from a non-root user account is trying to find Capistrano installed for that specific user rather than a system-wide install.
Can you run simply
gem install capistrano railsless-deploy capistrano-ext
As the user, without Sudo?
To answer your comment: It's generally not best practice to be installing and running cap deploy scripts as the root user. For your purposes maybe it will be OK, since you are doing a very limited task with Ruby/Cap; in the future, I would recommend looking into something like RVM.
RVM (Ruby Version Manager) is a tool you will be able to install system-wide, that then will manage your ruby version and gems per user.
