Syslinux - Jun 2006 - tftpd-hpa: remap '/tftpboot/ncd4/foo' into 'ncd4/foo'

Hello,

This about remapping in the HPA tftp server.

A client does request for '/tftpboot/ncd4/foo' which should be
'ncd4/foo'


I have created a remap file that looks now like this:

r tftpboot/ncd4/modshmx/login.hmx ncd4/modshmx/login.hmx
r tftpboot/ncd4/modshmx/setup.hmx ncd4/modshmx/setup.hmx
r tftpboot/ncd4/modshmx/term.hmx ncd4/modshmx/term.hmx

Because 

r tftpboot/ncd4/\(.*\) ncd4/\1

did not work for me. The manual says:

    The following escape sequences are recognized as part of the replace-
    ment pattern:

    \0     The entire string matched by the regex.

    \1 to \9
           The  strings  matched  by  each of the first nine parenthesized
           subexpressions, \( ... \), of the regex pattern.


Does someone have a working example of '\1' replacemant?


Cheers

After some sleep I tried

r tftpboot/ncd4/modshmx/\(.*\) ncd4/modshmx/\1

so there is no slash in the replacement, but it didn't help.

Try:

r tftpboot/ncd4/\(.*\)$	ncd4\/1

Also, you can just do:

r tftpboot/ncd4/	ncd4/

... since the pattern doesn't have to match the whole string.
