Ever forgotten to add a critical service to monitoring? Want to know if a service or process fails without explicitly monitoring every service on a host? …Then why not use SystemD’s existing knowledge of all the enabled services? Thanks to ‘Kbyte’ who made a simple Nagios plugin to do just this! Requirements Python3 (For RHEL/CentOS 7 yum install python34) python-nagiosplugin My pre-built RPMs or pip3 install nagiosplugin PyNagSystemD
Scripts and source available here: sql_ascii_to_utf8 The Goal To be able to take a Postgres Database which is in SQL_ASCII encoding, and import it into a UTF8 encoded database. Requirements: Python3 (For RHEL/CentOS 7 yum install python34) python-nagiosplugin My pre-built RPMs or pip3 install nagiosplugin PyNagSystemD The Problem PostreSQL will generate errors like this if it encounters any non-UTF8 byte-sequences during a database restore: # pg_dump -Fc test_badchar | pg_restore -d test_badchar_utf8 pg_restore: [archiver (db)] Error while PROCESSING TOC: pg_restore: [archiver (db)] Error from TOC entry 2839; 0 26852 TABLE DATA table101 postgres pg_restore: [archiver (db)] COPY failed for table "table101": ERROR: invalid byte sequence for encoding "UTF8": 0x91 CONTEXT: COPY table101, line 1 WARNING: errors ignored on restore: 1 And the corresponding data will be omitted from the database (in this case, the whole table, even the rows which did not have a problem): ...
The most common way to use rsync is probably as such: rsync -avr user@<source>:<source_dir> <dest_dir> Resulting in 30-35MB/s depending on file sizes This can be improved by using a more efficient, less secure encryption algorithm, disabling compression and telling the SSH client to disable some unneeded features that slow things down. With the settings below I have achieved 100MB/s (at work between VMs) and over 300MB/s at home between SSD drives. ...
Let’s pretend you have a project on Gitlab called ask-izzy and you want to mirror it up to Gitlab which is located at https://github.com/ask-izzy/ask-izzy Assuming you’re running Gitlab as the default user of git and that your repositories are stored in /mnt/repositories you can following something similar to the following instructions: Grant write access to Github Get your Gitlab install’s pubkey from the git user cat /home/git/.ssh/id_rsa.pub On Github add this pubkey as deploy key on the repo, make sure you tick the option to allow write access. ...
At the end of every year I note down a summary of the best applications, hardware & websites I’ve enjoyed & depended on throughout the year (and often for some time before).
