Python errors running s3cmd on Amazon AWS

Whenever I ran s3cmd on my AWS instance, I got the following errors:


/usr/lib/python2.6/dist-packages/S3/S3.py:9: DeprecationWarning: the md5 module is deprecated; use hashlib instead
/usr/lib/python2.6/dist-packages/S3/S3.py:10: DeprecationWarning: the sha module is deprecated; use the hashlib module instead


The problem is that this is an old, crappy version of s3cmd, 0.9.8.4. You can get version 0.9.9 using the instructions in the linked blog post. It’s just a matter of adding a new source to your apt-get sources list and then running apt-get update.

ssh_exchange_identification: read: Connection reset by peer

I got this while attempting to ssh into a VM on ubuntu. When I pinged the box, I got this:

PING 192.168.1.86 (192.168.1.86) 56(84) bytes of data.
64 bytes from 192.168.1.86: icmp_seq=1 ttl=64 time=0.614 ms
64 bytes from 192.168.1.86: icmp_seq=1 ttl=64 time=1.89 ms (DUP!)
64 bytes from 192.168.1.86: icmp_seq=2 ttl=64 time=0.602 ms
64 bytes from 192.168.1.86: icmp_seq=2 ttl=64 time=0.925 ms (DUP!)

Whoops! The VM was already running and had been granted the exact same IP. It was responding from two places at the same time, which was confusing the hell out of SSH. Just kill one of the boxes and you’re fine (DHCP release/refresh doesn’t work, because both boxes have the same MAC address).

Thanks to this thread for the hint.

I got this when trying to install the ruby thrift client. It’s trying to compile a native extension, which needs ruby 1.8 dev version. Simple fix:


sudo apt-get install ruby1.8-dev
