I am happy to announce a new major release of GNU poke, version 5.0.
GNU poke 5.0 release is now available at
https://ftp.gnu.o ... e/poke-5.0.tar.gz
The tarball is signed and you can get the PGP signature at
https://ftp.gnu.o ... ke-5.0.tar.gz.sig
GNU poke (http://www.j ... rch.net/poke) is an interactive, extensible
editor for binary data. Not limited to editing basic entities such
as bits and bytes, it provides a full-fledged procedural,
interactive programming language designed to describe data
structures and to operate on them.
I'd like to thank everyone who contributed to this release through code,
documentation, or testing.
What is new in this release:
commands (-p, --hserver-port).
uint<32> will be interpreted as a single-precision floating-point number
and uint<64> will be interpreted as a double-precision floating-point
number as defined per the IEEE 754 standard.
The following expressions are now supported:
- Addition: a .+ b
- Subtraction: a .- b
- Multiplication: a .* b
- Division: a ./ b
- Ceil-devision: a ./^ b
- Exponentiation: a .** b
- Remainder: a .% b
- Post-increment: a.++
- Pre-increment: .++a
- Post-decrement: a.--
- Pre-decrement: .--a
- Negation: .-a
- Less-than: a .< b
- Less-than-or-equal-to: a .<= b
- Greater-than: a .> b
- Greater-than-or-equal-to: a .>= b
- Equal-to: a .== b
- Not-equal-to: a .!= b
spaces! Extent of a PVM value mapped in a given IO space will be tracked
and values will be re-mapped only if a write happens in their extent; which
is a big performance win for read-intense programs.
length/size of an array with dynamic bound(s) to help the user to
understand the mistake.
fields. Previously write to nested fields of integral structs did not
materialize in IO space.
floating point numbers: sqrtf and sqrtd.
They accept uint<32> and uint<64> respectively as the IEEE 754 single and
double precision floating-point numbers.
to not break the ABI, and bump the version components according to the
libtool's recommendation (when needed).
are now accepting either pk_compiler or pk_val. This is the first step
toward removing global state from libpoke to be able to have multiple
instances of libpoke in a single process (and also to be able to accomplish
thread-safety). We're not there yet, but we'll be there some day (hopefully
soon)!
poke 1.0 by the rationale that it's not that useful of a flag. Turns
out it's quite useful to start from an empty file when assembling binary
files from scratch using poke.
fixed and the following methods has been added:
get_{file,owner_user,group}_name.
also add ptime_str function to get date/time information as a string.
modules, but we still cannot have poke executable for MinGW platform.
Help is very much appreciated in this area!
includes a bunch of corrections to the documentation! Cheers to them!
Happy poking!

Fail2ban ispeziona i log file (ad es. /var/log/apache/error_log) e banna IPs che mostrano un comportamento sospetto -- troppe password sbagliate, tentativi di exploits, etc. Generalmente Fail2Ban è quindi usato per aggiornare le regole del firewall al fine di rigettare gli indirizzi IP durante un intervallo di tempo settabile, benchè ogni altra azione (come l'invio di una mail di notifica) può anche altresì essere impostata. Tra le altre cose Fail2Ban mette a disposizione dei filtri per diversi servizi come apache, courier, ssh, etc.
Mostrerò brevemente come installare e configurare fail2ban per rigettare le connessioni di IP sospetti, specialmente quelli riguardanti la patch qmail-dnsrbl. Ciò evita di essere bannati noi stessi da spamhaus, che è gratuito solo fino a 100.000 query al giorno.
fail2ban richiede che si abbia un firewall come nftables o iptables attivo.
