[cs615asa] hw4 security groups

[Javed Akhtar]

Hi,

I am facing one problem regarding the SMTP part of assignment. When I am
trying to send email from one of the instance using the program 'mail' on
Stevens mail server i.e nexus.stevens.edu  567. I am getting an error saying
connection rejected. Is it something to do with security group? 

 

Also, I got an email from AWS saying that I reached a limit on the volume of
email that I can send out of SMTP port 25 on my instance. Does that mean, I
am actually able to send emails from my instance but the SMTP port is
blocked at Stevens so I am not able to receive those sent emails?

 

Thanks & Regards,

Javed Akhtar

Hey everyone,

 

I was under the impression that if two instances are in the same security
group they will be able to talk to each other, however it is still necessary
to allow udp inbound traffic so one can query the other via udp. Hopefully
this can help somone save some head beating against wall time.

 

Regards,
