>Description:
I am using mount_nwfs on FreeBSD 8.2-RELEASE. I use mount_nwfs to access a Novell NetWare 6.5 server. I noticed that there is no scheme for german filename translation, only swedish and koi8-r. After some searching, I found out that the source code for these conversions are in /usr/src/lib/libncp/ncpl_nls.c. So I created a scheme for german filename conversion.
The patch is attached. It changes the files /usr/src/lib/libncp/ncpl_nls.c and /usr/include/netncp/ncp_nls.h. Then libncp can be recompiled and the german scheme for filename conversion is available. It works perfectly for me.
I also noticed that there is another file ncp_nls.h in /usr/src/sys/netncp. I don't know how this file is related to the one in /usr/include/netncp, but probably the same change should be applied to that file too.
Apparently, NetWare uses the old IBM codepage 437 for character encoding. I use ISO 8859-1 on FreeBSD (locale de_DE.ISO8859-1). My translation table should work for other languages that use ISO 8859-1 as well, but I only tested it with german.
My patch has been reviewed by Boris Popov (bp at freebsd.org) and he found it ok.
>How-To-Repeat:
Mount a NetWare volume with mount_nwfs, which has files with german special characters in the filenames. On FreeBSD, these characters are incorrect.
>Fix:
Apply my patch to /usr/src/lib/libncp/ncpl_nls.c and /usr/include/netncp/ncp_nls.h. Then recompile libncp (simply execute make in /usr/src/lib/libncp). Copy the newly created libncp.so.4 to /usr/lib (backup original first!).
Then mount_nwfs can be executed with the option "-w de" to mount the NetWare volume again. The german special characters in the filenames are ok now.
