1. Apache 2.4 에 mod_cband 설치시 발생하는 에러
make 과정에서 아래와 같은 메시지 출력

mod_cband.c 파일을 편집합니다.
vi /usr/local/src/mod-cband-0.9.7.5/src/mod_cband.c
이때, src/.libs/mod_cband.c 라는 파일이 존재 않은 상태에서 작업해야 합니다.
빨간색은 수정 이전 라인, 파란색은 수정 이후 라인입니다.
1333번 라인
p.add.sin.s_addr = inet_addr(r->connection->remote_ip);
p.add.sin.s_addr = inet_addr(r->connection->client_ip);
1342번 라인
fprintf(stderr,”%s leaf %s\n”,r->connection->remote_ip,leaf);
fprintf(stderr,”%s leaf %s\n”,r->connection->client_ip,leaf);
1362~1365번 라인
if (c->remote_ip != NULL)
addr = inet_addr(c->client_ip);
else
addr = c->remote_addr->sa.sin.sin_addr.s_addr;
if (c->client_ip != NULL)
addr = inet_addr(c->client_ip);
else
addr = c->client_addr->sa.sin.sin_addr.s_addr;
위와 같이 수정한 다음 make 명령을 내리면 정상적으로 컴파일이 진행됩니다.

Libraries have been installed in:
/usr/local/apache/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR’
flag during linking and do at least one of the following:
– add LIBDIR to the `LD_LIBRARY_PATH’ environment variable
during execution
– add LIBDIR to the `LD_RUN_PATH’ environment variable
during linking
– use the `-Wl,-rpath -Wl,LIBDIR’ linker flag
– have your system administrator add LIBDIR to `/etc/ld.so.conf’
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
