screen: Attach attempt with bad pid

[stewe]

nazdar borci,

chcel som si pokusne rozbehnut screen, a to tak, ze jeden uzivatel nieco pise do terminalu v screene a druhy sa pripoji a pasivne pozera co ten druhy robi, isiel som na to takto

jo, mam mac os x 10.6.6, takze

xSup1-2:~ miklosovic$ screen -ls
No Sockets found in /tmp/screens/S-miklosovic.

takze spustim screen normalne
xSup1-2:~ miklosovic$ screen

potom Ctrl + : a napisem
multiuser on <enter>, napise ze ten mod je enabled
potom Ctrl + : a napisem
addacl molnarp <enter>
potom Ctrl + : a napisem
chacl molnarp -w "#"

potom detachnem screen a pozriem sa na pid
xSup1-2:~ miklosovic$ screen -ls
There is a screen on:
   61988.ttys000.xSup1-2   (Multi, detached)
1 Socket in /tmp/screens/S-miklosovic.

ok takze pid je 61988, takze dam screen -r, som spat
a teraz sa lognem na druhej konzole ako
user molnarp, zadam

xSup1-2:~ molnarp$ screen -r miklosovic/61988.ttys000.xSup1-2

a proste sa nic nestane a ked sa prepnem do mojho okna tak je tam presne ta hlaska,
ze "Attach attempt with bad pid(a tuna pid)"

este som pridal setuid bit na screen
xSup1-2:~ molnarp$ ls -la /usr/bin/screen
-rwsr-sr-x  1 root  wheel  628784 Nov 20  2009 /usr/bin/screen

obaja uzivatelia su v skupine wheel
xSup1-2:~ molnarp$ id
uid=503(molnarp) gid=20(staff) groups=20(staff),405(com.apple.sharepoint.group.4),404(com.apple.sharepoint.group.3),61(localaccounts),12(everyone),0(wheel),406(com.apple.sharepoint.group.5),403(com.apple.sharepoint.group.2),402(com.apple.sharepoint.group.1)

xSup1-2:~ miklosovic$ id
uid=502(miklosovic) gid=20(staff) groups=20(staff),405(com.apple.sharepoint.group.4),404(com.apple.sharepoint.group.3),61(localaccounts),12(everyone),0(wheel),406(com.apple.sharepoint.group.5),403(com.apple.sharepoint.group.2),402(com.apple.sharepoint.group.1)
