• ssh X11 forwarding issue

  - by bbuser

  I have put ForwardX11 in my ~/.ssh/config and then I start a X11 application like this: ssh -f user@host 'someapp; sleep 1' This works fine. The application someapp has a button which opens a viewer application via a shell script viewer.sh. When I press the button the viewer comes up. This is all good and as expected, but if I do ssh -2 -f user@host 'someapp; sleep 1' there's trouble. someapp starts very well, but if I click the button the viewer doesn't show up. As the viewer is called via a shell script, I replaced the call with xclock and the situation was exactly the same - I think the viewer is not to blame. The situation is the same on Linux and AIX. The reason I need -2 is that I finally want to use connection multiplexing and this does only work with version 2. The reason for the sleep 1 is that it didn't work otherwise;-) To add more confusion, with ssh -2 -f user@host 'xterm &; app; sleep 1' the viewer works as long as the xterm is open. When I close xterm ssh -v outputs the following debug1: channel 1: FORCE input drain debug1: channel 0: free: client-session, nchannels 3 debug1: channel 1: free: x11, nchannels 2 and from that moment the viewer doesn't show when I press the button. I also replaced the viewer application with a script that writes the $DISPLAY variable to a file. The variable is always set correctly.

• Reproducible file corruption for files on windows share

  - by bbuser

  We have about 40 file servers in our intranet to distribute software packages. The servers have names like example01, example02 etc. Every name resolves to a single IP-address (A-record) and the IP resolves back to that name (PTR) for every single server. The thing is, that for a certain file (mypackage.cab) I get different results depending on whether I use: \\192.0.2.01\fs\pkg\X12345678 or \\example01.foo\fs\pkg\X12345678 While in one case the file is correct in the other case the file has exactly the right size, but it is all zeros. For a certain combination of client and server I can reproduce this reliably. It doesn´t matter if I download in Windows Explorer, via robocopy or even from Linux with smbclient. It´s always the same, one file corrupt, the other ok. It happens only for certain combinations of clients and servers, not others. For example: client01 example01.foo -> OK (192.0.2.01 is also OK) client01 example02.foo -> broken (but 192.0.2.02 is OK) client02 example01.foo -> broken (but 192.0.2.01 is OK) client02 example02.foo -> OK (192.0.2.02 is also OK) client03 example06.foo -> OK (but 192.0.2.06 is broken) client03 example07.foo -> OK (192.0.2.07 is also OK) etc... In some cases I get the broken file when I use the IP address in other cases when I use the name. For every client the majority of servers is Ok, but from every client I tested I have at least 4 cases of broken files. All this happens only for mypackage.cab (about 5k in size), it never happened for any of the other files in the same directory. Confused? Certainly I am. Any idea what can cause this or any idea what to try to figure it out is welcome. Clients are Windows XP. Servers are NetApp filers I don´t have access to. I can (and will) contact the filer team again, but first I have to have an idea what is going on.

• Why do I have to unserialize this serialized value twice?

  - by 55skidoo

  What am I doing wrong here? I'm serializing a value, storing it in a database (table bb_meta), retrieving it... OK so far... but then I have to unserialize it twice. Shouldn't I be able to just unserialize once? This seems to work, but I'm wondering what point about serialization I'm missing here. //check database to see if user has ever visited before. $querystring = $bbdb->prepare( "SELECT `meta_value` FROM `$bbdb->meta` WHERE `object_type` = %s AND `object_id` = %s AND `meta_key` = %s LIMIT 1", $bbtype, $bb_this_thread, $bbuser ); $bb_last_visits = $bbdb->get_row($querystring, OBJECT); //if $bb_last_visits is empty, add time() as the metavalue using bb_update_meta if (empty($bb_last_visits)) { $first_visit = time(); echo 'serialized first visit: ' . $bb_this_visit_time_serialized = serialize(array($bb_this_thread => $first_visit)); bb_update_meta( $bb_this_thread, $bbuser, $bb_this_visit_time_serialized, $bbtype ); //add to database, bb_meta table echo '$bb_last_visits was empty. Setting first visit time as ' . $bb_this_visit_time_serialized . '<br>'; } else { //else, test by unserializing the data for use. echo 'last visit time already set: '; echo $bb_last_visits->meta_value; echo '<br>'; //fatal error - echo 'unserialized: ' . $bb_last_visits_unserialized = unserialize($bb_last_visits[0]->meta_value); echo '<br>'; echo 'unserialize: ' . $unserialized_visits = unserialize($bb_last_visits->meta_value); echo '<br>'; echo 'hmm, need to unserialize again??: '; echo $unserialized_unserialized_visits = unserialize($unserialized_visits); echo '<br>'; echo 'hey look, it\'s an array value I can finally use now. phew: ' . $unserialized_unserialized_visits[$bb_this_thread]; }
