Linux – In the /etc/hosts/ file on Linux/OSX, how to do a wildcard subdomain

linuxlocalhostmac-osxunix

I need to test sub-domains on my localhost. How can I effectively have this result of adding *.localhost.com to my /etc/hosts/ file?

If it's not possible, how do I work around this problem? I need to test wildcard sub-domains on my localserver. It is a Django devserver, can the Django dev server handle the sub-domains? Can some other piece of software/routing give me the end result I want?

I have written a dns proxy in Python. It will read wildcard entries in /etc/hosts. See here: https://github.com/hubdotcom/marlon-tools/blob/master/tools/dnsproxy/dnsproxy.py

/etc/hosts file being ignored

I found the problem.

The /etc/hosts file had overly restrictive permissions -rw------ (I believe that is 600 octal). Changing that to mode 644 fixed the problem.

My tests with ping were done with ordinary priv, and the hosts file was unreadable. My original problem was getting postgresql to startup properly; it starts with root privilege, but apparently sheds priv before starting its child processes for autovacuum and such, so by the time it needed a domain resolved, it could not read the hosts file.

Thanks to everybody who replied. It has been enlightening.

Linux – How to reach max network throughput in Linux

Just on the topic of maxing traffic, instead of writing your own udp test program, iperf (iperf package in Debian/Ubuntu) is a great tool to generate TCP bandwidth, but it require a remote host with Linux with same or better network capacity:

Remote host:

# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------

On host I want to test:

iperf -i 1 -c 192.168.15.6
------------------------------------------------------------
Client connecting to 192.168.15.6, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[  3] local 192.168.15.132 port 37163 connected with 192.168.15.6 port 5001
