debugserver failed to create socket

[liuxuan30]

Hi there,

I followed here on iOS <11.2 and Electra 1.0.4 (old one) to launch debugserver.
Steps:
1 create two proxies

$ iproxy 6666 6666 &
$ iproxy 2222 22 &

2 ssh into device, run jailbreakd_client and launch the debugserver. For example, to debug AppStore app:

$ /electra/jailbreakd_client <the appstore pid> 1
$ /Developer/usr/bin/debugserver localhost:6666 -a <the appstore pid>

3 launch LLDB and attach to it. Everything works fine.

However, on Electra 1131, with same steps, I got several error message, something like

debugserver(libsystem_network.dylib)[3028] : __nwlog_err_simulate_crash_libsystem libsystem simulate crash failed "libsystem_network.dylib: netcore_create_control_socket :: socket(PF_SYSTEM, SOCK_DGRAM, SYSPROTO_CONTROL) failed [1: Operation not permitted]"

There are some more, but all are about libsystem_network and socket errors.

I'm not sure what's going on. Is this new Electra1131 issue, or what I miss? Thanks!

I’d love to know the solution to this :)

what are you doing here? @KingKong5147 don't post meaningless comments.

[KingKong5147]

Meaningless ?...... First of all I can write what I like and secondly I have an issue with Debugserver on iOS 11.3.1 which you had working on iOS 11.1.2. I asked for help . If you don’t like go Fuck yourself .

Alright, blocked and reported. You post my profile link above, which helps nothing, and you want to know the solution, fine, you have the right, but you have to follow the community rules to ask help. Your language and tone will get you no help anymore, at least from me.

My debugserver can't work fine on 11.3, too.
I tried jailbreakd_client pid 1/2/6, nothing can help.
It shows that:
Attaching to process xxxx...
Listening to port xxxx for a connection from localhost/xxx.xxx.x.xx...
Failed to get connection from a remote gdb process.
Exiting.
