nginx, flask, and file downloads
Okay so here's the setup:
[-] The primary server API is exposed via Flask (Python) and all static files, including all html, css, js is served by nginx.
[-] Python is exposing an API at url http://domain.com/api/download/<file_id>, where file_id is a database id for the file that we're interested in downloading.
1. User wants to download a file, so we spawn a new window with the url '/api/download/<file_id>'
2. Nginx intercepts the request, sees that it starts with /api/, and then forwards the request to Flask, which is being served on port 5000.
3. Flask routes the request to its download method, retrieves the pertinent data from the file_id, and constructs additional header settings to make nginx happy and to force the browser to see the file stream as a download request instead of the browser just trying to open the file in a new window. Flask then returns the modified header stream to nginx
4. Nginx is finally ready to do some work. While parsing the headers for the incoming request, it encounters "X

Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs

Report how many days before and http ssl certificate expire. I've also provided a template if you want to use it with Zabbix as an External Check: - Configure ExternalScripts variable in zabbix_server.conf - Put the script in the external script folder (I've used /etc/zabbix/externalscripts/) - Import the template & assign it to your host. - Wat…

Easy way to do a mysqldump and restore using netcat (this is NOT encrypted)
#####
# You'll be needing two machines, the target machine and source one (makes sense, right)?
#####
# On the target machine
nc -l 55555 | gzip -d -c | mysql <database name> -u<user> -p<password> [ | <decrypt> ]
#####
# On the source machine
mysqldump -u<user> -p<password> <database name> | gzip | nc <ip of target server> 55555 [ | <encrypt> ]
