Re: wu 2.6.2 compiled on RH 7.3 has B in dir listing

My guess is that it is using the internal ls instead of the external binary.
There's an off-by-one error in the rpad function in ftpd.c, which can cause
spurious characters to be written to a couple of the fields, right where
you're seeing the B's.

If this is the problem, you can either recompile so that it no longer uses the
internal ls, or you can make a trivial edit to the source code and recompile.

The rpad function in ftpd.c includes the following lines

        a = (char *) malloc(len + 1);
        memset(a, ' ', len-1);
        a[len] = 0;

You need to change the middle one to

        memset(a, ' ', len);

to fix the problem in the internal ls.

Cheers, Bob
