GDPI seems to be having issues since yesterday in UAE. Still works but it’s struggling (random SSL errors).
anyone else facing the same thing or is it just me? Tested on Windows/MacOS/iOS using similar programs and techniques and I see issues everywhere.
@toodle has provided PCAP dumps, and it looks very similar to Saudi Arabia (probably the same DPI manufacturer, ntc.party is blocked as well).
Workaround as for now:
goodbyedpi.exe -6 -e 130
It will work only for Firefox though.
and why would it work only on firefox and nowhere else?
Try this one
goodbyedpi.exe -6 --frag-by-sni
You still need to disable Kyber, as there’s no segment reassembly.
chrome://flags → kyber → disable
goodbyedpi.exe -6 -e 130 works for some sites, but not others. Specifically https://www.redgifs.com/ seems to not be working. And goodbyedpi.exe -6 --frag-by-sni doesn’t seem to be working at all. I get this error:
unknown option -- frag-by-sni
Usage: goodbyedpi.exe [OPTION...]
-p block passive DPI
-r replace Host with hoSt
-s remove space between host header and its value
-a additional space between Method and Request-URI (enables -s, may break sites)
-m mix Host header case (test.com -> tEsT.cOm)
-f <value> set HTTP fragmentation to value
-k <value> enable HTTP persistent (keep-alive) fragmentation and set it to value
-n do not wait for first segment ACK when -k is enabled
-e <value> set HTTPS fragmentation to value
-w try to find and parse HTTP traffic on all processed ports (not only on port 80)
--port <value> additional TCP port to perform fragmentation on (and HTTP tricks with -w)
--ip-id <value> handle additional IP ID (decimal, drop redirects and TCP RSTs with this ID).
--dns-addr <value> redirect UDPv4 DNS requests to the supplied IPv4 address (experimental)
--dns-port <value> redirect UDPv4 DNS requests to the supplied port (53 by default)
--dnsv6-addr <value> redirect UDPv6 DNS requests to the supplied IPv6 address (experimental)
--dnsv6-port <value> redirect UDPv6 DNS requests to the supplied port (53 by default)
--dns-verb print verbose DNS redirection messages
--blacklist <txtfile> perform circumvention tricks only to host names and subdomains from
supplied text file (HTTP Host/TLS SNI).
This option can be supplied multiple times.
--allow-no-sni perform circumvention if TLS SNI can't be detected with --blacklist enabled.
--set-ttl <value> activate Fake Request Mode and send it with supplied TTL value.
DANGEROUS! May break websites in unexpected ways. Use with care (or --blacklist).
--auto-ttl [a1-a2-m] activate Fake Request Mode, automatically detect TTL and decrease
it based on a distance. If the distance is shorter than a2, TTL is decreased
by a2. If it's longer, (a1; a2) scale is used with the distance as a weight.
If the resulting TTL is more than m(ax), set it to m.
Default (if set): --auto-ttl 1-4-10. Also sets --min-ttl 3.
DANGEROUS! May break websites in unexpected ways. Use with care (or --blacklist).
--min-ttl <value> minimum TTL distance (128/64 - TTL) for which to send Fake Request
in --set-ttl and --auto-ttl modes.
--wrong-chksum activate Fake Request Mode and send it with incorrect TCP checksum.
May not work in a VM or with some routers, but is safer than set-ttl.
Could be combined with --set-ttl
--wrong-seq activate Fake Request Mode and send it with TCP SEQ/ACK in the past.
--native-frag fragment (split) the packets by sending them in smaller packets, without
shrinking the Window Size. Works faster (does not slow down the connection)
and better.
--reverse-frag fragment (split) the packets just as --native-frag, but send them in the
reversed order. Works with the websites which could not handle segmented
HTTPS TLS ClientHello (because they receive the TCP flow "combined").
--max-payload [value] packets with TCP payload data more than [value] won't be processed.
Use this option to reduce CPU usage by skipping huge amount of data
(like file transfers) in already established sessions.
May skip some huge HTTP requests from being processed.
Default (if set): --max-payload 1200.
LEGACY modesets:
-1 -p -r -s -f 2 -k 2 -n -e 2 (most compatible mode)
-2 -p -r -s -f 2 -k 2 -n -e 40 (better speed for HTTPS yet still compatible)
-3 -p -r -s -e 40 (better speed for HTTP and HTTPS)
-4 -p -r -s (best speed)
Modern modesets (more stable, more compatible, faster):
-5 -f 2 -e 2 --auto-ttl --reverse-frag --max-payload (this is the default)
-6 -f 2 -e 2 --wrong-seq --reverse-frag --max-payload
I’m on Firefox 126.0.1 and GoodbyeDPI v0.2.2.
You need to build from source, v0.2.2 (Mar 21 2022) doesn’t have the --frag-by-sni option (~3 days ago)
If you read path\to\ then you have to replace that part with the actual path to the folder because that wouldn’t work.
Assuming you’re on windows you just need to get w64devkit, GoodbyeDPI-master, and WinDivert 2.2.2-A
Extract all of these to their own folders and make note of their names, then add w64devkit/bin to your PATH (refer to the next step/dropdown)
Open up CMD as an administrator and run
cd path\to\GoodbyeDPI-master\src
Then run
make CPREFIX=x86_64-w64-mingw32- BIT64=1 WINDIVERTHEADERS=path\to\windivert\include WINDIVERTLIBS=path\to\windivert\amd64
If there weren’t any issues it should have resulted in a goodbyedpi.exe file being made in GoodbyeDPI-master\src, you want to copy goodbyedpi.exe, WinDivert.dll and WinDivert64.sys over to your existing installation of GoodbyeDPI v0.2.2 and replace all in the x86_64 folder.
Now you should be able to use --frag-by-sni
Sorry for any bad writing/incorrect information, I’d wrote this based off of what I’d did
ValdikSS, а у этого параметра --frag-by-sni вообще нет значений? Просто использовать как есть?
Я думаю, вы можете использовать его как есть, без дополнительных значений (см. скриншот выше). Translated using DeepL
