Good day Folks! Working on a bridging firewall/gateway and attempting to solve the age-old mystery of whether I can get NAT to work across a gateway that has 2 NICs and requires a bridge... Upside is, I have the gateway working, bridging works (as does OpenVPN using that bridge). But NAT does not in Fedora Core 4... >From dmesg: Linux version 2.6.11-1.1369_FC4 So I went to the website and downloaded the 1.1 source to build it. It needed libsysfs.h and it was not on my server. Went to the libsysfs website and downloaded 2.0 and built it with no obvious issues. The .h file is now there. Back to brctl and building it. ./configure --prefix=/usr Works like a champ. No errors. make (errors - looks like one big one) for x in libbridge brctl doc; do make -C $x ; done make[1]: Entering directory `/software/bridge/bridge-utils-1.1/libbridge' gcc -Wall -g -I/usr/src/linux/include -c libbridge_devif.c In file included from libbridge_devif.c:28: libbridge_private.h:39:2: error: #error Using wrong kernel headers if_bridge.h libbridge_private.h:43:2: error: #error Using wrong kernel headers sockios.h is libbridge_devif.c: In function âbr_get_bridge_infoâ: libbridge_devif.c:196: error: âSYSFS_BRIDGE_ATTRâ undeclared (first use in this libbridge_devif.c:196: error: (Each undeclared identifier is reported only once libbridge_devif.c:196: error: for each function it appears in.) libbridge_devif.c:196: error: syntax error before string constant libbridge_devif.c:197: error: syntax error before string constant libbridge_devif.c:198: error: syntax error before string constant libbridge_devif.c:199: error: syntax error before string constant libbridge_devif.c:200: error: syntax error before string constant libbridge_devif.c:201: error: syntax error before string constant libbridge_devif.c:202: error: syntax error before string constant libbridge_devif.c:203: error: syntax error before string constant libbridge_devif.c:204: error: syntax error before string constant libbridge_devif.c:205: error: syntax error before string constant libbridge_devif.c:206: error: syntax error before string constant libbridge_devif.c:207: error: syntax error before string constant libbridge_devif.c:208: error: syntax error before string constant libbridge_devif.c:210: error: syntax error before string constant libbridge_devif.c:212: error: syntax error before string constant libbridge_devif.c:213: error: syntax error before string constant libbridge_devif.c:214: error: syntax error before string constant libbridge_devif.c:216: error: syntax error before string constant libbridge_devif.c: In function âbr_get_port_infoâ: libbridge_devif.c:296: error: âSYSFS_BRIDGE_PORT_ATTRâ undeclared (first use in libbridge_devif.c:296: error: syntax error before string constant libbridge_devif.c:297: error: syntax error before string constant libbridge_devif.c:298: error: syntax error before string constant libbridge_devif.c:299: error: syntax error before string constant libbridge_devif.c:300: error: syntax error before string constant libbridge_devif.c:301: error: syntax error before string constant libbridge_devif.c:302: error: syntax error before string constant libbridge_devif.c:303: error: syntax error before string constant libbridge_devif.c:304: error: syntax error before string constant libbridge_devif.c:305: error: syntax error before string constant libbridge_devif.c:306: error: syntax error before string constant libbridge_devif.c:308: error: syntax error before string constant libbridge_devif.c:310: error: syntax error before string constant libbridge_devif.c: In function âbr_read_fdbâ: libbridge_devif.c:468: error: âSYSFS_BRIDGE_FDBâ undeclared (first use in this make[1]: *** [libbridge_devif.o] Error 1 make[1]: Leaving directory `/software/bridge/bridge-utils-1.1/libbridge' make[1]: Entering directory `/software/bridge/bridge-utils-1.1/brctl' make[1]: *** No rule to make target `../libbridge/libbridge.a', needed by `brct make[1]: Leaving directory `/software/bridge/bridge-utils-1.1/brctl' make[1]: Entering directory `/software/bridge/bridge-utils-1.1/doc' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/software/bridge/bridge-utils-1.1/doc' Apparently it does not like something... Any ideas? Did a make clean and configure again Re-downloaded and unpacked the source - same error(s). Would like to get some form of NAT working between this kernel, iptables 1.3.0 and bridge utils. Any help would be appreciated! Thank you. Jerome -- FRWS WebMail (http://www.frws.com) Cause you deserve Spam and Virus free email...
