Im implementing custom authentication using AWS api gateway and Lambda functions. In Chalice documentation, its stated that I need a authorizer_id to link the lambda function with the desired authentication.
@app.route('/authenticated', methods=['GET'], authorization_type='CUSTOM', authorizer_id='ab12cd')
def authenticated():
return {"secure": True}
Question: Where can I find the authorizer_id for my custom authorizer?
Is there any way to set a Docker containers system time dynamically (at run time) without effecting the host machine?
Using
hwclock --set --date "Sat Aug 17 08:31:24 PDT 2016"
gives the following error:
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --debug option to see the details of our search for an access method.
Using
date -s "2 OCT 2006 18:00:00"
gives the following error:
date: cannot set date: Operation not permitted
Use case:
I need to test time sensitive software (behaviour depends on the date).
Other common use cases:
Im developing a web-based application, using Angular2 as front-end and Django 1.10 as back-end, and Nginx as web-servers interface.
Should Angular2 access the Django API through api.mydomain.com or mydomain.com/api/?
I have seen examples of both, and I want to know the pros and cons.
Ive noticed that AWS's DNS service (Route53) appends a dot (.) at the end of every DNS url:
ns-xxx.awsdns-yy.co.uk.
ns-xxx.awsdns-yy.net.
ns-xxx.awsdns-yy.org.
ns-xxx.awsdns-yy.com.
Question: Is this a bug, or should I include the . in my DNS settings?
I've noticed that my Django application from time to time makes double database queries, instead of just one. The log file shows two similar requests at (almost) the exact same time.
Example:
[pid: 749|app: 0|req: 892/2837] x.x.x.x () {44 vars in 896 bytes} [Fri Sep 9 12:00:55 2016] GET /clinic_profile/61 => generated 0 bytes in 1 msecs (HTTP/1.1 301) 3 headers in 134 bytes (1 switches on core 0)
[pid: 750|app: 0|req: 659/2838] x.x.x.x () {44 vars in 898 bytes} [Fri Sep 9 12:00:55 2016] GET /clinic_profile/61/ => generated 84989 bytes in 374 msecs (HTTP/1.1 200) 3 headers in 102 bytes (1 switches on core 0)
This is a critical flaw in my system and I need to fix it asap.
Question: How can I filter out double requests?
Im using Django, Nginx and Ubuntu 14.04
By coincidence I looked at my servers ssh log (/var/log/auth.log) and I noticed that someone is constantly trying to gain access:
Sep 7 13:03:45 virt01 sshd[14674]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=116.31.116.42 user=root
Sep 7 13:03:48 virt01 sshd[14674]: Failed password for root from 116.31.116.42 port 13423 ssh2
Sep 7 13:03:52 virt01 sshd[14674]: message repeated 2 times: [ Failed password for root from 116.31.116.42 port 13423 ssh2]
Sep 7 13:03:52 virt01 sshd[14674]: Received disconnect from 116.31.116.42: 11: [preauth]
This happens a few times every minute, and has been going on for a long time without me knowing about it.
Question Should I be concerned about this, if yes: What should I do about it?
Im using Amazon EC2 to host a few websites on a single instance. From time to time I need to rescale my instance type. This requires a shut-down of the instance, and after relaunch the instance have gotten a new public IP address. This requires me to change the DNS config (very annoying), which takes up to 12 hours before it works.
Im pretty sure that im doing something wrong here, so my question is: Whats the best approach?
Im using nginx as load balancer in a dockerized setup. Im trying to get the http_geoip_module up and running so I can redirect traffic based on users geographical position.
Question:
The command nginx -V outputs --with-http_geoip_module=dynamic.
Does this mean that the geoip_module is installed? Its the =dynamic that confuses me, this detail does not appear in the tutorials im following.
