Symbolic links are easy to spot with ls. Hard links are more difficult for a 
couple of reasons.
First, by definition, a hard link is simply another entry in a directory 
with the same inode. (Use ls -ali).
  INODE             LINKS
 6411 drwx------   3 gaf gaf     120 2005-09-01 09:05 Personal
The directory, Personal has 3 hard links:
1. The entry in the parent directory name personal.
2. The entry in the Personal directory itself (the .)
 6411 drwx------   3 gaf gaf   120 2005-09-01 09:05 .
3. A subdirectory always has an entry for its parent, this is the ..
 6411 drwx------  3 gaf gaf   120 2005-09-01 09:05 ..

scp _should_ ignore the . and .. entries. If you have a subdirectory in the 
uleopold tree that has the same inode as uleopold that could be causing the 
problem. I've seen this thing occur on Linux (rarely) after a crash. 
Normally, the system will prevent you from doing this, but it has happened 
to me, primarily as a result of a bad power supply. I would possibly 
suspect that since 10.3.10.8:/home/uleopold/* worked, that scp might have a 
bug in it, which is why I suggested logging in to the 10.3.10.8 system, and 
issuing the cp -rp 10.3.10.8:/home/uleopold /var/tmp
