Hi,

I'm currently using rdesktop 1.8.1 built from sources and I saw
something strange:

rdesktop is continuously asking for the same license file.

Here is a strace output of a fresh start (no .cal in
~/.local/share/rdesktop/licenses/):


[admin@S777TXDTTEST ~]$ strace -o rdesktop.trace /usr/bin/rdesktop -x
0x86 -N -a 16 -P -z -k en-us S777SQ01 -u ''
Failed to negotiate protocol, retrying with plain RDP.
[admin@S777TXDTTEST ~]$ ls .^C
[admin@S777TXDTTEST ~]$ cat rdesktop.trace |grep lice
open("/home/admin/.local/share/rdesktop/licenses/09dcea473ad6f1ca5c33bc89=
df88aa42560b82b4.cal",
O_RDONLY|O_LARGEFILE) =3D -1 ENOENT (No such file or directory)
stat64("/home/admin/.local/share/rdesktop/licenses",
{st_mode=3DS_IFDIR|0700, st_size=3D4096, ...}) =3D 0
open("/home/admin/.local/share/rdesktop/licenses/ebbcc14692930d5d3f71925f=
6cc657ec02fa02cf.cal.new",
O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0600) =3D 5
rename("/home/admin/.local/share/rdesktop/licenses/ebbcc14692930d5d3f7192=
5f6cc657ec02fa02cf.cal.new",
"/home/admin/.local/share/rdesktop/licenses/ebbcc14692930d5d3f71925f6cc65=
7ec02fa02cf.cal")
=3D 0


What we see here is:

1. search for 09dcea473ad6f1ca5c33bc89df88aa42560b82b4.cal file
2. fail to open it (it doesn't exists)
3. write to another file something (a new TSE license?)
4. close this new file

If I re-launch rdesktop, then the same file (09...) is asked, not found
and another _new_ CAL file is created. At this point, I have 2 CAL files.=


If I mv the latest CAL to the wanted CAL (09...), here is what I have:

[admin@S777TXDTTEST ~]$ cd .local/share/rdesktop/licenses/
[admin@S777TXDTTEST licenses]$ ls
0f6f3932c9ecff5b253edabc71d017de013a1778.cal
ebbcc14692930d5d3f71925f6cc657ec02fa02cf.cal
[admin@S777TXDTTEST licenses]$ mv
0f6f3932c9ecff5b253edabc71d017de013a1778.cal
09dcea473ad6f1ca5c33bc89df88aa42560b82b4.cal
[admin@S777TXDTTEST licenses]$ strace -o rdesktop.trace
/usr/bin/rdesktop -x 0x86 -N -a 16 -P -z -k en-us S777SQ01 -u ''
Failed to negotiate protocol, retrying with plain RDP.
[admin@S777TXDTTEST licenses]$ cat rdesktop.trace |grep lice
open("/home/admin/.local/share/rdesktop/licenses/09dcea473ad6f1ca5c33bc89=
df88aa42560b82b4.cal",
O_RDONLY|O_LARGEFILE) =3D 5
[admin@S777TXDTTEST licenses]$ ls
09dcea473ad6f1ca5c33bc89df88aa42560b82b4.cal
ebbcc14692930d5d3f71925f6cc657ec02fa02cf.cal  rdesktop.trace

Then it's ok, the 09... CAL is reused (we see a read() and close() of
this file) and no extra CAL created.



Then, two questions :

* is this behaviour the expected one?
* does this behaviour can be responsible about an over consumption of
TSE licenses?

Thanks.
