Bug 491536

I confirm that the same bug appears in Centos 5, even when using clusterssh-3.25 (rebuilt from rawhide spec + latest upstream sources).

I am not sure if this is related or not, but in F-10 I get:

([wolfy@wolfy ~]$  cssh zoli
Cannot open pipe for reading when talking to zoli: No child processes
Use of uninitialized value $win in concatenation (.) or string at /usr/bin/cssh line 792.
Protocol error: bad 3 (Window); Sequence Number 8
 Opcode (10, 0) = UnmapWindow
 Bad resource 0 (0x0)
 at /usr/bin/cssh line 799

I am still unable to admin multiple servers using cssh in Fedora 11.

I can also confirm the bug on 32-bit:

$ cat /etc/redhat-release
Fedora release 10.93 (Leonidas)
$ uname -r
2.6.29.1-111.fc11.i586
$ rpm -q clusterssh
clusterssh-3.22-2.fc11.noarch
$ rpm -q perl-Tk
perl-Tk-801.028-7.fc11.i586
$ cssh foo
no event type or button # or keysym at /usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi/Tk/Widget.pm line 1105.
 at /usr/bin/cssh line 1434

This seems to be a bug in perl-tk package - the line mentioned in the error message is some windows-specific code which (afaik) should not be executed on linux. (I've downloaded few other perl-tk utilities from web and lots of them crashes with the same error but work when the line is commented out)

Adding perl-tk's maintainer to CC-list.

Andreas, could you please take a look at this bug and reassign it to your component, if it's perl-tk issue?

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

More information and reason for this action is here:

I was able to resolve the issue by patching the file 
/usr/lib64/perl5/vendor_perl/5.10.0/x86_64-linux-thread-multi/Tk/Widget.pm with a patch from http://bugs.gentoo.org/attachment.cgi?id=178622&action=view.

$ cat /etc/redhat-release

diff of Widget.pm, After patching with the perl-tk-804.028-Widget-mousewheel-bind.patch from Bryan D. Stine <battousai> 

$ diff Widget.pm Widget.pm.orig

<   }

clusterssh is working for me..

Unsurprisingly, even with the above patch I still get:
# cssh root@biblioteca

[wolfy@wolfy tmp]$ rpm -q perl-Tk

Sorry Manuel, the patch above was intended just for the error:

no event type or button # or keysym at
/usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi/Tk/Widget.pm line
1105.

This seems to be the same problem as described in bug #489228 comment #8.  I've attached a patch there that seems to remedy both.  I think we can effectively call one a duplicate of the other.  Comments?

Unfortunately that patch does not fix the error that I see :( I get the exact same error, even after rebuilding for Fedora 10 the current perl-Tk + perl-Tk-fix.patch from  bug #489228 . The error is identical to the one pasted in comment #7 .

Okay, going back to comment #7 and attempting to duplicate that error...

# uname -r;rpm -q clusterssh perl-Tk
2.6.27.24-170.2.68.fc10.x86_64
clusterssh-3.22-1.fc9.noarch
perl-Tk-804.028-5.fc9.x86_64

Doing a straightforward `cssh root@host` works.  I think there's something else at play here.  Crud.

same problem here:

uname -r;rpm -q clusterssh perl-Tk
2.6.29.4-167.fc11.x86_64
