Ziggo Amsterdam Osdorp de Aker: netwerk-ID 4444, frequentie 164000, Modulatie 64QAM, Symboolfrequentie 6900

Posted by jpluimers on 2019/12/16

Since Ziggo had two URLs giving wrong/correct setup for digal TV, here is the thread and the correct information:

“Dit is fout:Frequentie: 47400, 474000 of 474Netwerk-ID: 4444 of 04444Modulatie: 64-QAMSymboolsnelheid: 6875Dit is goed:Vul bij het netwerk-ID 4444 in.Vul bij frequentie 164000 in.Selecteer bij Modulatie 64QAM.Vul bij Symboolfrequentie 6900 in.2/…”

Correct information for Ziggo Amsterdam de Aker:

  • netwerk-ID 4444,
  • frequentie 164000,
  • Modulatie 64QAM,
  • Symboolfrequentie 6900

Great tip from: [Archive.is] Michal Špaček on Twitter: “Friendly reminder: if you allow users to register email addresses on your domain, make sure they can’t get: admin@ administrator@ hostmaste… https://t.co/wUHXrQC2J0”:

 Friendly reminder: if you allow users to register email addresses on your domain, make sure they can’t get:
  • admin@
  • administrator@
  • hostmaster@
  • postmaster@
  • webmaster@ (and others from RFC 2142)

otherwise users might be able to get an HTTPS certificate for your domain.

CHMOD – Applying Different Permissions For Files vs. Directories – Server Fault

Posted by jpluimers on 2019/12/16

The answers at [WayBack] CHMOD – Applying Different Permissions For Files vs. Directories – Server Fault describe various ways to do this. Depending in why/when you want to change them you’d probably favour different ones, so be sure to read the answers.

I mostly use these combinations:

find . -type d -exec chmod 700 {} \;
find . -type f -exec chmod 600 {} \;

and

find . -type d -exec chmod 775 {} \;
find . -type f -exec chmod 664 {} \;

And since I forget how to do ocatal too often:

commonly used permissions:

Permission COMMAND
---------   ------------------
rwxrwxrwx   chmod 777 filename
rwxrwxr-x   chmod 775 filename
rwxr-xr-x   chmod 755 filename
rw-rw-rw-   chmod 666 filename
rw-rw-r--   chmod 664 filename
rw-r--r--   chmod 644 filename

permissions are divided into 3 divisions. The first rwx is for the owner. The next 3 is for the group. The last 3 is for everyone else.

rwx------  owner permissions - read, write, executable
---rwx---   group permissions - rwx
------rwx   other permissions - rwx
