When testing a new MTA configuration, most administrator make an SMTP connection by hand using telnet. That fine, but there is a little tool to simplify the job: swaks
To send a mail to the local MTA with a from ex@ample.com to the adress foo@bar.org:
# swaks -f ex@ample.com -t foo@bar.org -s 127.0.0.1Further Reading and sources
When doing a vzctl enter from an OpenVZ hypervisor you go inside the container but… without any environment variables :
hypervisor:~# vzctl enter container
entered into VE 101
container:/# echo $LANG
container:/# su -
container:~# echo $LANG
en_US.UTF-8
You can workaround this ‘problem’ by patching the /root/.bashrc from the container to execute a su - like this :
if [ "$LANG" = "" ]; then
exec su -
