Unexpected Tilde character on directoryname

[Mohamad Djuarsa]

Hi,

I encountered problem in my HP-UX 11.23 while today ,suddenly there was a new directory with tilde character and 1 number in the directory name.
I've tried to trace for some logs ,but there are no any user except me who has login to this machine today.

i.e
original directoryname: /directory/mydir
the new directoryname: /directory/mydir~1

although the original directory is still there.
could you anyone to help me to find out the reason why this new directory has created ?

thx,
-dju

Hello Mohamad,

a) Do you, by any chance share this directory
with Windows users (Samba, for example)?
I have seen funny issues like yours when
Windows users have access to Unix directories.

Each file system decides how it wants to implement short file names in Windows.

For example, Windows 95 uses the "~n" method exclusively. Long file names will contain a tilde for the first 9999 files with the same name:

longfi~1 longfi~2...

After that it seems to start randomizing the
end bit.

Windows NT adds the hexadecimal hash overflow technique.

Some file systems (like Novell) just truncate
the name. "Long dirname for file.txt" on a
Novell server will come out to
"LONGDIRN.TXT".

b) Strange directory and file names can also
be created by incorrect CTRL-C or similar
sequence.

c) Who is the owner of the directory and
what are its permissions? Is the directory empty? What is the datestamp of
last modification?

d) Can you list directories for
unprintable characters:

ls -alb /directory/mydir
ls -alb /directory/mydir~1
ls -alb /directory

a) I will ask to IT application support in my office first, since Windows 2003 for client which point to this directory for upload data thru application..
c) no, there are some files from windows which uploaded to this directory thru application.
for the ACL please see the following list below :

Hello,

I am almost confident that it is Windows
client that is causing it.
Depending on the setup of your
Samba on the HP-UX server and the way the
Windows users access the files,
they probably save the original versions
before making changes.
