Operating Systems Solaris Restarting inetd picks up environment, passed on via telnet Post 302660513 by mde on Friday 22nd of June 2012 02:49:09 PM

Restarting inetd picks up environment, passed on via telnet

Curious problem I just encountered: needing to restart inetd, I su'd to root and executed the usual commands
Code:
# /etc/init.d/inetsvc stop
# /etc/init.d/inetsvc start

Shortly after this, users started reporting unexpected behaviour after logging in with telnet, and it turned out they all had environment variables set to values that only I would use.

It appears (at least, this is the only explanation I have been able to come up with) that inetd inherited my environment (carried over via su) when I executed the 'inetsvc start' script, and telnet, and thence the login shell, then also inherited that environment.

Has anyone else noticed this? Is this a bug? Or should I have restarted the service some other way?

NAME
micro_proxy - really small HTTP/HTTPS proxy SYNOPSIS
micro_proxy DESCRIPTION
micro_proxy is a very small HTTP/HTTPS proxy. It runs from inetd, which means its performance is poor. But for low-traffic sites, it's quite adequate. It implements all the basic features of an HTTP/HTTPS proxy, in only 260 lines of code. To install it, add a line like this to /etc/inetd.conf: webproxy stream tcp nowait nobody /usr/sbin/micro_proxy micro_proxy Make sure the path to the executable is correct. Then add a line like this to /etc/services: webproxy port/tcp Change "port" to the port number you want to use - 3128, or whatever. Then restart inetd by sending it a "HUP" signal, or rebooting. On some systems, inetd has a maximum spawn rate - if you try to run inetd services faster than a certain number of times per minute, it assumed there's either a bug of an attack going on and it shuts down for a few minutes. If you run into this problem - look for syslog messages about too-rapid looping - you'll need to find out how to increase the limit. Unfortunately this varies from OS to OS. On Free- BSD, you add a "-R 10000" flag to inetd's initial command line. On some Linux systems, you can set the limit on a per-service basis in inetd.conf, by changing "nowait" to "nowait.10000".
