Description of problem:
In /usr/share/rhn/register/rhnreg.py:49 :
proxyHost = cfg.readEntry("httpProxy")[7:]
last '[7:]' clause makes it cut the proxy name, it it cannot connect to it.
Steps to Reproduce:
1. Configure an HTTP proxy
2. edit /etc/sysconfig/rhn/rhn_register to go to the proxy
3. add a print statement after line 49 in /usr/share/rhn/register/rhnreg.py
Actual Results: trashed proxy URL
Expected Results: good proxy URL
There is more to say about RHN register proxy facility:
1. It is a HUGE pain in the ass to expect users to figure out they have to
edit a text config file in order to just start a registration process, when
those users are behind a firewall.
2. rhn_register itself does nothing to identify a problem - it blocks for
some 5 minutes, than bails out.
Here is what should be done:
1. HTTP proxy setting should be system-global. All programs must grok it:
- ask during system setup
- set in /etc/sysconfig/... and suck into shell as a bunch of *_proxy
- Modify Netscape/Mozilla to grok these env variables
- modify up2date, rhn_register to do the same
2. Make rhn_register smarter:
- don't let it block - user should be able to cancel it
- make it print a friendly message 'Connecting to <proxy URL>'
- in case of proxy connect error make it print it clearly
3. In fact, rhn_register could probably be implemented as Web-based
registration process... Have to think out all the details though...
Just figured it out: this [7:] crap is for 'http://' - so the comment is
One more complaint - you should be smarter in parsing the proxy specs - should
be able to grok both formats. Other complaints still hold.
Editting of a text file is not necessary, as you can easily run 'rhn_register
--config' and do it from there. As for there needing to be global proxy
settings, I agree, but I don't think that's a knock on rhn_register/up2date, as
Netscape/Mozilla also require that you configure them for proxy before they will
be very useful to you after installation.
Well, to be honest, I had no idea about '--config' option. OTOH, why would
rhn_register be configurable using an option, while up2date would have a special
program for that? Also, when being run on an unregistered machine, why wouldn't
rhn_register go into the configuration mode automagically instead of promptly
trying to access the [unavailable] Internet? Same holds for up2date.
As for Netscape/Mozilla proxy - that's exactly what I suggested:
1. Tweak source code of both to pay attention to *_proxy env. vars. Good way to
do it would be the following logic:
- if personal proxy settings in Netscape/Mozilla configs are explicitly set -
- otherwise, if *_proxy are set - use those and save them in personal configs
- If env vars' values differ from personal configs - warn about it (possibly
once) and offer to save new values in personal configs.
2. Set the aforementioned variables - it is essential, you guys have some
centralized tool to tweak all configs - preferably text-mode, like Yast. This
would set all system config parameters, beginning with proxy settings, to the
firewall config to hard drive parameters tweaking...
The comment is not wrong as the attribute should not have a "http://"
according to the comment during configure:
Attribute Name: httpProxy
Comment: HTTP proxy in host:port format, e.g. squid.redhat.com:3128
In that case, the '[7:]' part in the aforementioned line of Python code is
wrong. Anyway, this is NOT relevant for a PROPER fix. The latter should:
1. be able to read proxy in ANY format
2. read proxy from centralized resource rather than from it's own config file
3. inform the user about its current operation in a non-blocked fashion to allow
the user to cancel.
added more robust proxy name parsing...
It now understands "foo.bar.com:2341" and "http://foo.bar.com:23423"
btw, there is already a web based RHN registration system, but it is
somewhat limited (difficult to get the package list, hardware profiles,
etc...). But it does allow you to generate a system id and get the box
also, rhn_register and up2date both support the "--config" option. In the
case of up2date, the gui version is implemented as a seperate utility.
work on making the app less blocky has begun as well...
