Subject: ftpfs change to compensate for some servers
Date: Thu, 9 Nov 1995 15:02:02 -0500


some FTP servers include . and .. in the list, which messes up
common commands applied to a mounted ftpfs directory.
the following change prevents them from being seen:

vortex% diff $home/cd/cmd/ftpfs /sys/src/cmd/ftpfs/proto.c

> static int	isdotdot(char*);
670a672,673
> 			if(isdotdot(field[7]))
> 				return 0;
681a685,686
> 			if(isdotdot(field[8]))
> 				return 0;
692a698,699
> 			if(isdotdot(field[9]))
> 				return 0;
