Am I going crazy?

[Michael Jinks <mjinks bsd uchicago edu>]

On my machine I have a directory called "/home/software".  Here's a
listing:

[mjinks putzel software]$ pwd
/home/software
[mjinks putzel software]$ ls -l
total 6
-rw-rw-r--   1 root     bsdis         395 Sep 28 23:18 README
drwxr-sr-x   2 mjinks   bsdis        1024 May  4 20:55 gzip
drwxr-sr-x   2 mjinks   bsdis        1024 Sep 28 23:18 linux
drwxr-sr-x   6 mjinks   bsdis        1024 Sep 28 20:09 solaris
drwxr-sr-x   2 mjinks   bsdis        1024 Sep 28 23:13 sources
drwxrwsr-x   2 mjinks   bsdis        1024 Sep 28 23:13 uploads


Within that directory, there is a directory called "ssh".  But it
doesn't show up in ls:

[mjinks putzel software]$ find . -type d -name ssh -print
./ssh
[mjinks putzel software]$ ls
README	 gzip	  linux    solaris  sources  uploads


I've tried examining the directory in various ways.  For example:

[mjinks putzel software]$ file ssh
ssh: setgid directory
[mjinks putzel software]$ stat ssh
  File: "ssh"
  Size: 1024         Filetype: Directory
  Mode: (2755/drwxr-sr-x)         Uid: (  500/  mjinks)  Gid: ( 1023/  
bsdis)
Device:  3,8   Inode: 473091    Links: 3    
Access: Thu Sep 30 22:24:55 1999(00000.00:01:00)

Change: Tue Sep 28 15:07:37 1999(00002.07:18:18)


I can go into it and look around.  It contains what I expect:

[mjinks putzel software]$ cd ssh
[mjinks putzel ssh]$ ls -al
total 1010
drwxr-sr-x   3 mjinks   bsdis        1024 Aug 17 15:44 .
drwxr-sr-x   8 root     bsdis        1024 Oct  1 03:21 ..
drwxr-sr-x   4 mjinks   bsdis        3072 May 12 11:20 ssh-1.2.27
-rw-r--r--   1 mjinks   bsdis     1022546 May 13 16:28 ssh-1.2.27.tar.gz
-rwxr-xr-x   1 mjinks   bsdis         331 Aug 17 15:43 sshd.INITSCRIPT


The "total 1010" above strikes me as odd, but moving along:

I can copy the directory to another name and it shows up fine.  I can
move the directory to another name and it shows up fine:

[mjinks putzel software]$ su
Password: 
[root putzel software]# cp -rp ssh ssh.two 
[root putzel software]# ls
README	 gzip	  linux    solaris  sources  ssh.two  uploads
[root putzel software]# mv ssh ssh.three
[root putzel software]# ls
README	   linux      sources	 ssh.two
gzip	   solaris    ssh.three  uploads

But try as I might, I just can't have a file in /home/software named
"ssh" show up in a listing:

[root putzel software]# touch ssh
[root putzel software]# ls
README	   linux      sources	 ssh.two
gzip	   solaris    ssh.three  uploads
[root putzel software]# file ssh
ssh: empty


See!?!?  The file exists, but it won't show up in ls!


What sort of thing causes this?
