Folks, I am writing a script that will export the tags for a running instance as environment variables. Problem with autoscaling groups, is that these tags are not available to the instance.
How does one know which autoscaling group an instance belongs to via api/aws cli commands? I need to use instance tags in scripts, however, they are not available. Suggestions?
Thanks!
Folks, Trying to setup Locust in AWS using latest amazon linux. After installing locust, i get the following when starting in master mode:
locust -f foo.py --master
Traceback (most recent call last):
File "/usr/bin/locust", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in <module>
working_set.require(__requires__)
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require
needed = self.resolve(parse_requirements(requirements))
File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: requests>=2.4.1
What would be the most elegant fix for this? Thanks
Folks, Please correct me if I am wrong, but I was under the assumption that the reason rsync's first run is slower than subsequent, is because it builds up a database of the file structure on the sender.
However, Im not seeing this in the docs: http://rsync.samba.org/how-rsync-works.html
Does rsync in fact build a database of local files? Can we specify where it should be stored?
Thanks!
Folks, As we know, the 3.x kernels have higher TCP default connection values, such as initcwnd and initrwnd. For 2.x friends, is there a way to set these in /etc/sysctl.conf instead of the ip route way?
Instead of the following:
sudo ip route change default via 192.168.1.1 dev eth0 proto static initcwnd 10
Is there a way to set the same in /etc/sysctl.conf?
Thanks
it must be 2 am in the morning... and ive had zero sleep. Nonetheless... I am trying to get my developer to send me a public ssh key. If the guy sends you a file that begins with:

Thanks! )

Trying to load balance my app with the use of an AWS Elastic Load Balancer. The app is a custom TCP-based sender/receiver.
In any case, ELB seems to send 100% of the traffic to one machine, neglecting the other healthy attached instance.
I see no options in changing the round/robin behavior...
Suggestions? Thanks!
I have a web server which is quite heavy on the mysql server:
Here is a graph of questions being executed on the database:
Is there a way to increase the max questions allowed? You see how the graph tops off and stays around 5K while the web server is active?
Yes, other things are being done on the code side of things, just wondering what we can do in my.cnf. All tables are already being served from /dev/shm.
Thanks!
DNS servers that are pre-configured on EC2 instances seem to be only: 172.16.0.23
Does anyone know if thats a dedicated DNS VIP for a specific region? Should we add more DNS servers in for fault tolerance?
We have our mysql servers behind a load balancer which is masking the original IP address.
Is there any way we can log the connection requests in MySQL?
There is either a misconfigured app somewhere that is triggering authentication requests. Increasing the max_connect_errors would be a hack... its better to find the incorrectly coded page.
Thanks
Gents, Trying to insert a google analytics/piwik javascript bit in the footer of the stream.
For some reason, I dont think you can do this with ProxyPass/ ProxyPassReverse/ vhosts...
If someone can point me in the right direction, it would be greatly appreciated!

For whatever reason, I am not able to include the following line in my httpd.conf:
AuthBasicProvider file ldap
I keep getting the following error:
Unknown Authn provider: ldap
Apache is compiled from source with :
--enable-authnz-ldap
--enable-ldap
What other compile-time options should I pass? Building this for svn/ldap servers, compiling support in instead of dso.
Thanks! V

After having a bit of a fiasco with clvmd, I would like to start from scratch, and really not use clvmd, since in my case its almost not needed. I can easily have 'lvscan' incorporated in higher management things like ... puppet.
In any case, how does one fix the:
connect() failed on local socket: No such file or directory
Internal cluster locking initialisation failed.
WARNING: Falling back to local file-based locking.
Volume Groups with the clustered attribute will be inaccessible.
Would fdisk /emcpowerpath, pvcreate /emcpowerpath, and recreating the VG fix this issue?

trying to spit out last 100 lines of catalina.out and email them to myself. Can someone suggest a quick oneliner on how to do this?
I can only come up with something like:
tail -100 catalina.out | /bin/mail -s blah myemailaddress
seeing the following in my mysql error log file:
InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes

110927 18:36:37 [ERROR] Plugin 'InnoDB' init function returned error.

How can this be easily fixed?

Trying to join a osx machine on a dhcp network which forces certain client IDs.
Even if I was to modify the client-id via the network properties, the DHCP server is not accepting this request, since Windows and Apple send this via different options
You can set the ClassID in the Network Control Panel in the DHCP Client ID box. The trick lies in setting up your DHCP server to recognize it. Windows XP sends the DHCP class ID via DHCP option 77, and OS X sends it via option 61. You'll have to set your DHCP server to check for option 61, +with an offset of 1 and a length of 9+. That's the tricky bit.
So, without modifying the DHCP server... (which does not belong to me), is there anything that can be done on OSX to modify the client-id option to be 77?
I am trying to reproduce a .iso (of clonezilla), needed a proprietary driver to work. I had to unpack, unsquashfs, add a driver, resquash, re-iso the distribution....
Now, I am trying to re-create a bootable .iso :) An iso that will not be written to DVDs, but to usbs rather, or be booted into xen/kvm/etc...
Every attempt has failed so far... here is the general syntax I am using:
>$ cat makemeanewiso.sh
genisoimage -r -v -V "CASPER" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ../bootme.iso .
If I download a clonezilla image, and do the following to it :
mount -o loop clonezilla.iso tmp/
mkdir tmp2 && cp -Rf tmp/* tmp2/
run the makemeanewiso.sh from here
Then, the iso does not boot with a xen DomU, but boots just fine if burnt to a DVD :)
Can someone please help me out with mkisofs options to make a good iso?

Gents, what would you recommend for production use in a FC environment, where live migration is a must?
Which clustered file system should we use? OCFS2?
Would you still need drbd?
Thanks!
