Attempting To Send Inventory - Invalid Host? SVN 4193

[Sebastian Roth]

@Tom-Elliott And I guess you can’t reproduce this on your system?!

@Raymond-Bell How many clients do you have? Could you please run this command on your FOG server:

lsof -i :3306
COMMAND   PID     USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
apache2 22534 www-data   12u  IPv4 21769312      0t0  TCP localhost:43411->localhost:mysql (ESTABLISHED)
mysqld  24347    mysql   10u  IPv4 20564983      0t0  TCP localhost:mysql (LISTEN)
mysqld  24347    mysql   31u  IPv4 21769313      0t0  TCP localhost:mysql->localhost:43411 (ESTABLISHED)

Maybe you need to install it first. Package in debian is called ‘lsof’ just like the tool itself.

[Tom Elliott]

@Uncle-Frank of course I can’t. I believe you’re on the right track though as I only have one or two clients connecting to my system. And most of the time they are off to begin with. So it isn’t a surprise to me if it is related to sheer numbers of clients connecting and disconnecting. I’m of the mind though that it’s my attempt to use the real connect after initializing the mysqli object in lib/db/MySQL.class.php and missing some check somewhere as this is a fairly new issue, not one people have been experiencing the whole time.

[Sebastian Roth]

Searching through the forums I saw that Raymond Bell and Joseph Hales both mentioned those errors in apache log some time ago. For example see here: https://forums.fogproject.org/topic/5661/web-interface-slow-svn-4333

Browsing the code history around that time I found this: http://sourceforge.net/p/freeghost/code/3971/

Why a connect call (in the query function) which wasn’t there before?

[Tom Elliott]

@Uncle-Frank The reasoning is that in some cases the connection just appears to go dead. So on the construct (which is already called) it automatically makes the link, rather than implicitly making it do so.

[Sebastian Roth]

@Raymond-Bell And while you are at it. Please run the same command using port 80 again. My guess is that you see a lot of apache processes in the first listing (port 3306) and it would be interesting to see “who” is calling all these (connections from your clients is my guess): lsof -i :80

[Raymond Bell]

@Uncle-Frank Nothing show up running
Ubuntu 12.04

fog@fog-virtual-machine2:~$ lsof -i :3306
fog@fog-virtual-machine2:~$```

@Raymond-Bell Hi, is it new hosts or hosts that are disappeared that you want to register ? I’ve a same problem with my FOG server, some mac address are missing in the mac address table, I’ve to delete all hosts which are not in the mac address table to register it.

[Raymond Bell]

@ch3i This is a host that was reg and then was missing from fog a week later. I will check the mac address table

[Raymond Bell]

@ch3i I can see the host in the Host Listing Export and it does not have a mac address but when i do a search under host i can not find it. How would i delete it out of the Host Listing Export? Also i get a blank page when i try to look at report Hosts and Users

You have the same bug than me, some mac address disappeard and I can’t view it in the host view… can you post the result of

SELECT hostName 
FROM hosts 
WHERE hostID NOT IN ( SELECT hmHostID FROM hostMAC );

[Raymond Bell]

@ch3i And all are missing from fog Host Search

mysql> SELECT hostName 
    -> FROM hosts 
    -> WHERE hostID NOT IN ( SELECT hmHostID FROM hostMAC );

@Raymond-Bell Have you updated to current trunk since yesterday? I really wonder why you do not see any mysql connections on your FOG server. Maybe this issue was solved just by itself. Well then you might want to head for your initial problem and I think ch3i is pointing you the correct way!

Yes i have updated to 4199
Hopefully @ch3i can help me delete these out of here and then i can re-register them

[Raymond Bell]

I have deleted all that where in the list and got the host to register.

[Wayne Workman]

For future readers, the select statement that @ch3i posted can be converted into a delete statement like so:

DELETE hostName 
FROM hosts 
WHERE hostID NOT IN ( SELECT hmHostID FROM hostMAC );
