getting current UNIX uid
Hello, I am trying to get the user that is running the scripts uid, I have had a look at the pwd module and it does not appear to offer that functionality. Is there any way within python to get that information ? Regards, Johhny -- http://mail.python.org/mailman/listinfo/python-list
Python password display
Hello, I am currently writing some python code which requires the use of a password. Currently I am using the raw_input function to take the users input in and use it. One problem with that is the password is displayed in clear text on the console of the server. I would like to work on a way around that. Is there any built in method to do that or any how-to's around the Internet / Advice that I could research? Regards, Johhny. -- http://mail.python.org/mailman/listinfo/python-list
regular expressions and matches
Hello,
I have recently written a small function that will verify that an IP
address is valid.
==SNIP==
import re
ipAddress = raw_input('IP Address : ')
def validateIP(ipAddress):
ipRegex =
r"^([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])\.([01]?\d\d?|2[0-4]\d|25[0-5])$"
re_ip = re.compile(ipRegex)
match = re_ip.match(ipAddress)
if not match:
print "an error has occured with ipAddress"
return match
else:
return match
print(validateIP(ipAddress))
==SNIP==
I was having issues trying to get my code working so that I could pass
the IP addresses and it would return a true or false. When it matches I
get something that looks like this.
python ip_valid.py
IP Address : 192.158.1.1
<_sre.SRE_Match object at 0xb7de8c80>
As I am still attempting to learn python I am interested to know how I
could get the above to return a true or false if it matches or does not
match the IP address. I would also like to expand that so that if the
IP is wrong it requests the IP address again and recalls the function.
I have done the same thing in php very easily but python appears to be
getting the better of me. Any assistance and advice would be greatly
appreciated.
Regards,
Johhny

Hello, Thankyou for your response, If I check that the errara_package value is with a print I get the following. ===SNIP=== Updated libc-client packages that fix a buffer overflow issue are now available.

replacing \n characters in a hash
Hello,
I am currently trying to write some scripts to get information from the
xmlrpc for redhat network. One of the issues I am having is trying to
strip off the special characters in the hash that is returned. Here is
an example of the information returned within the hash :
===SNIP===
{'errata_update_date': '2005-12-06', 'errata_topic': 'Updated
libc-client packages that fix a buffer overflow issue are
now\navailable.\n\nThis update has been rated as having moderate
security impact by the Red\nHat Security Response Team.',
'errata_type': 'Security Advisory', 'errata_notes': '',
'errata_synopsis': 'Moderate: libc-client security update',
'errata_references': '', 'errata_last_modified_date': '2006-01-25
10:37:24', 'errata_issue_date': '2005-12-06', 'errata_description':
'C-client is a common API for accessing mailboxes.\n\nA buffer overflow
flaw was discovered in the way C-client parses user\nsupplied
mailboxes. If an authenticated user requests a specially
crafted\nmailbox name, it may be possible to execute arbitrary code on
a server that\nuses C-client to access mailboxes. The Common
Vulnerabilities and Exposures\nproject has assigned the name
CVE-2005-2933 to this issue.\n\nAll users of libc-client should upgrade
to these updated packages, which\ncontain a backported patch that
resolves this issue.'}
===SNIP===
What I would like to do is remove the \n characters from
'errata_topic'. Which is this section of the hash.
Updated libc-client packages that fix a buffer overflow issue are
now\navailable.\n\nThis update has been rated as having moderate
security impact by the Red\nHat Security Response Team.
What I had attempted to do is use the replace() function but it
consistantly comes up with the following errors:
Traceback (most recent call last):
File "rhn_errata.py", line 63, in ?
errata_package = errata_package.strip('\n','')
AttributeError: 'dict' object has no attribute 'strip'
where errata_package is JUST the errata_topic hash value.
Any advice would be great on how to do that.
Regards,
Johhny

reading files
Hello All,
I am working my way through learning python as a language. I am having
some issues with something that looks right and does not work. I am
trying to get myself more familure with reading files. Based on the
tutorials at www.python.org This "should" work. but im not sure what
the issue is.
===SNIP===
import string
vsftpd=open('vsftpd.conf', 'r')
print vsftpd
vsftpd.read()
vsftpd.readlines()
vsftpd.close()
===SNIP===
When I check the permissions to ensure they are correct I get the
following.
stat vsftpd.conf
File: `vsftpd.conf'

Modify: 2005-12-16 12:34:00.0 +
Change: 2005-12-16 12:34:00.0 +
When I run the script I get the following:
python reading_file.py
Does anyone have any advice on this issue at all.

text manipulation
Hello, I am trying to write a script in python (to replace a perl script with limited functionality). Now I have some issues. Currently I am using the perl to load the file then regex parse certain lines to remove characters (uncomment lines and change variables). I would like to take that into the python script. I have had a look at the module "string" and I dont think its what Im looking for. Here is an example of some text I would like to manipulate #comment here #user_defined_variable = no # I would like to make that #comment here user_defined_variable = yes # With perl/sed Its very easy, However Im having issues to do it in python.

Re: newbie to python
Hello,
If I go into the python shell and type help("modules") It does show
that crypt is there. However Im unsure if that means that there is help
or its got the module installed.
>From a dpkg --list python* I have
ii python2.4-crypto
2.0+dp1-2ubuntu1 cryptographic
algorithms and protocols for Python
Which means it should work. However Im not really getting anything from
it. Which makes me wonder.
