dndx / shadowsocks-libuv Goto Github PK

After shadowsocks-python update and use sendall(), server will sometimes not be able to complete handshake process. The problem had been identified. If you are using shadowsocks-python, please use commit 8c5c40915ea8fbd22a0f1a6a9596010565118b35 as a temporary solution, I will fix server ASAP.

when run with user nobody at port 10086
I got this error

2013-01-09 12:02:50 FATAL: fopen failed, Permission denied on File: server.c Line: 563

change the port to another heigher port did not work ,either.

Is there any possible to run this with out root privilege? (Or add this into Your @todo)？
Thanks for reading this.

RC4 have a very simple algorithm and can be implemented in just few lines of code. According to my test, we only need the EVP_BytesToKey(3) to make password derivation. It seems that EVP_BytesToKey(3) is using PKCS#5 v1.5 so it's possible just implement this algorithm and throw openssl dependency away.

In my encrypt.c , I just used EVP_BytesToKey(3) to do derivation. After that I used a rc4 implementation I found in OpenBSD Directory and it's working very well.

Looks like travis do not have openssl installed on their worker, trying to put openssl into project.

when I use make to build this project in mac. I get a unknow error.
$ make
cc -Wall -O2 -DNDEBUG -I libuv/include -std=gnu99 -L/usr/local/opt/openssl/lib -I/usr/local/opt/openssl/include -o
server server.c utils.c encrypt.c md5.c rc4.c

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [all] Error 1

How to solve that?!!Please

For easy deployment, I choose to use static linking by adding -static to CFLAGS. This will result getaddrinfo segfault.

There's some problem in static linked program which loads pthread and uses getaddrinfo. More info in ths glibc bugzilla thread.

No problem in your code, just create this issue to notify you about this problem. Maybe you can add this in README so other people will not waste time doing this again.

错误如下：
cc -Wall -O2 -DNDEBUG -I libuv/include -std=gnu99 -o
server server.c utils.c encrypt.c md5.c rc4.c
libuv/libuv.a -lpthread -lcrypto -lm -lrt
server.c: In function after_write_cb :
server.c:151: warning: dereferencing type-punned pointer will break strict-aliasing rules

I built shadowsocks-libuv by MinGW32 toolchain with some small fix in Makefile:
LIBUVFLAGS = "OS=mingw"
CFLAGS += -D_WIN32_WINNT=0x0600 -I"f:/openssl-0.9.8k_WIN32/include"
LDFLAGS += f:/openssl-0.9.8k_WIN32/lib/ssleay32.lib f:/openssl-0.9.8k_WIN32/lib/libeay32.lib -lws2_32 -lmswsock -lkernel32 -luser32 -lgdi32 -lpsapi -liphlpapi -lmsvcr110

Building is successful, but report error when running, never succeed:
