Mac OS X - libproxychains4.dylib coult not be inserted about proxychains-ng

[rofl0r]

"A lot of the time" means it works sometimes and sometimes not ? this sounds strange...

try to run with gdb
i.e. gdb --args proxychains4 nmap foo bar

paste the backtrace (bt) when it receives the SIGTRAP.

i suspect some problem in the mac dynlinker.

It is strange, curl for example works fine.
My gdb output:
Starting program: proxychains4 -f src/proxychains.conf nmap nmap.org
Reading symbols for shared libraries +........................ done
[proxychains] config file found: src/proxychains.conf
[proxychains] preloading ./libproxychains4.dylib

Program received signal SIGTRAP, Trace/breakpoint trap.
0x0000000000000000 in ?? ()

well nmap works usually with pcap so on a completely different layer which is not really compatible with proxychains.

only nmap's syn scan could theoretically be compatible with proxychains. that's its only mode that works straight with libc sockets.

the SIGTRAP backtrace is not useful at all...

Ok, that is too bad. Thanks for the response though.
