This can be overridden by mounting the filesystem with the "-oallow_other" mount option, a/c to the fuse FAQ (http://apps.sourceforge.net/mediawiki/fuse/index.php?title=FAQ#Why_don.27t_other_users_have_access_to_the_mounted_filesystem.3F), but when I try to specify this on the archfs command line it is rejected with 'Error: no such option; see man archfs' (which incidentally does not exist). You're right -- archfs does not pass options on to the underlying fuse system. It really should. Here's a quick fix for you: In archfs.c, around line 27, change:     args[2] = "-d";     return fuse_main(2, args, &operations, NULL); to:     args[2] = "-d";     args[3] = strdup("-oallow_other");     return fuse_main(3, args, &operations, NULL); If that doesn't work, change the first argument of fuse_main from 3 to 4. (I'm not sure what argc is supposed to be there ...) Thanks Andrew, after some messing around I found that this works: change line 27-30 to: args[2] = strdup("-oallow_other"); args[3] = "-d"; return fuse_main(3, args, &operations, NULL); I think that the first argument in 'return fuse_main' refers to the number of arguments in args, although args[2]="-d" in the previous code this is actually ignored (it is the debug mode). My change still ignores the '-d' but uses the '-oallow_other'. (I could enable '-d' I think by setting the first argument of fuse_main to 4. In fact your 2nd suggestion would have worked - running in debug mode.) Now I have another problem! I can see the archfs filesystem through Samba (e.g. in Windows Explorer), but it wrongly shows directories as zero-length files. To be more precise, I can see the 'date' directories (e.g. 2008_11_17_18_50_42) but inside these I see directories as zero-length files, and of course I can't navigate into these sub-directories. This is not a fuse problem because sshfs works fine, it must be something in archfs. I have tried archfs with -s option (instead of -t default), but it is just the same (-l option does not seem to work at all). Any suggestions gratefully received... Dominic
