Hallo
I've got some Problems with Cygwin using XDMCP. I'm try to connect to an kdm.
After caling XWin.exe -query 192.168.220.2 just an X appears and disappears
some minutes later.
On the kdm-host I found the follwing in kdm.log:
------------------
Xlib: connection to "10.75.7.71:0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
------------------
This message appears five times for every connecting-attempt.
I have tried useing the -from switch, but it didn't change anything.
I tried to connect form the same host with XWin32 and from an Linux Box with
XFree86 and both worked.
After that I sniffed a bit arround with ethereal and found something strange:
a working connection looks like this:
xfreehost -> kdmhost XDMCP Query
kdmhost -> xfreehost XDMCP Willing
xfreehost -> kdmhost XDMCP Request
kdmhost -> xfreehost XDMCP Accept (with cookie)
xfreehost -> kdmhost XDMCP Manage
xfreehost -> kdmhost XDMCP Manage
xfreehost -> kdmhost XDMCP Manage
kdmhost -> xfreehost TCP SYN
xfreehost -> kdmhost TCP SYN, ACK
kdmhost -> xfreehost TCP ACK
kdmhost -> xfreehost X11 Initial Connection Request (with cookie)
xfreehost -> kdmhost TCP ACK
xfreehost -> kdmhost TCP Replies/events
kdmhost -> xfreehost TCP ACK
...
...
...
A connection useing Cygwin looks like this:
cygwinhost -> kdmhost XDMCP Query
cygwinhost -> kdmhost XDMCP Query
cygwinhost -> kdmhost XDMCP Query
kdmhost -> cygwinhost XDMCP Willing
cygwinhost -> kdmhost XDMCP Request
cygwinhost -> kdmhost XDMCP Request
cygwinhost -> kdmhost XDMCP Request
kdmhost -> cygwinhost XDMCP Willing
cygwinhost -> kdmhost XDMCP Request
cygwinhost -> kdmhost XDMCP Request
kdmhost -> cygwinhost XDMCP Willing
kdmhost -> cygwinhost XDMCP Accept (with cookie)
kdmhost -> cygwinhost XDMCP Accept (with another cookie)
kdmhost -> cygwinhost XDMCP Accept (with another cookie)
cygwinhost -> kdmhost XDMCP Manage
kdmhost -> cygwinhost XDMCP Accept (with another cookie)
kdmhost -> cygwinhost XDMCP Accept (with another cookie)
cygwinhost -> kdmhost XDMCP Manage
cygwinhost -> kdmhost XDMCP Manage
---- Theses two messages sometimes apper later (beetwen the TCP)
cygwinhost -> kdmhost XDMCP Manage
cygwinhost -> kdmhost XDMCP Manage
cygwinhost -> kdmhost XDMCP Manage
---- This block apears five times
kdmhost -> cygwinhost TCP SYN
cygwinhost -> kdmhost TCP SYN, ACK
kdmhost -> cygwinhost TCP ACK
kdmhost -> cygwinhost X11 Initial Connection Request (with last cookie)
cygwinhost -> kdmhost TCP Replies/events ("Invalid MIT-MAGIC-COOKIE-1 key")
cygwinhost -> kdmhost TCP FIN, ACK
kdmhost -> cygwinhost TCP ACK
kdmhost -> cygwinhost TCP FIN, ACK
cygwinhost -> kdmhost TCP ACK
---- the last message
kdmhost -> cygwinhost XDMCP Failed
Can someone explain, why cygwin sends three Querys, and five requests
messages?
Has someone an idea?
Thanks
Anton
P.S.: If someone ist interested in the Ethereal log Files - just ask (about 10
kB)
