| Summary | 0003308: restartdansguardian.py write wrong configs | ||||||||||
| Description | When I apply some access policy in proxy with content filter, the same (proxy/dansguardian) doesn't work anymore or block everything. After some analysis the log and config files was found a problem in python script restartdansguardian.py. The problem is on listing the directories that is being considered as a string. When the number of content filters exceeds 9 (nine), coming close 10 or more content filter, the list is inverted. Listing with normal number: 1, 2, 3, 4, 5, 6, 7, 8, 9 e 10. Listing using string: 1, 10, 2, 3, 4, 5, 6, 7, 8 e 9. It does dansguardian manages configs with incorrect information, send value in variable "groupname" with totally wrong config of the content filter. i.e. the config file dansguardianf10.conf responsible for Segurança group, had "groupname" variable with value "Custo content2". Solving problem took the following steps, wich gave north to debug python script: # ls -1 /etc/dansguardian/profiles/ [ Here it shows the listing as if it was string. ] # ls -1 /etc/dansguardian/profiles/ | sed "s/^\(.\)$/0\1/" | sort | sed "s/^0\(.\)$/\1/" OR # ls -1 /etc/dansguardian/profiles/ | sort -n [ Here we saw how the list should be. ] After checking the script was not finding anything. When running the command below, we had the answer: # restartdansguardian -d [ Show where the script error. ] Now enter in file /usr/local/bin/restartdansguardian.py # vi /usr/local/bin/restartdansguardian.py We look for line containing ".Include" and moving to fuction "def getprofiles()" responsible for creation of content filters. The process took to run debug line by line in the fuction getprofiles. def getprofiles(): if file_exists(DANSGUARDIAN_SETTINGS): profiles = glob(DANSGUARDIAN_SETTINGS) else: profiles = glob(DANSGUARDIAN_SETTINGS_DEFAULT) profiles += glob("%s/*/settings" % DANSGUARDIAN_PROFILES) profiles = sorted(map(lambda p: os.path.dirname(p), profiles)) debug(profiles) return profiles The process. # python Python 2.4.6 (0000001, Nov 10 2009, 07:02:03) [GCC 3.4.6 20060404 (e 3.4.6-10.endian8)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import os >>> import glob >>> profile = glob.glob ("/var/efw/dansguardian/settings") >>> profiles = glob.glob ("/var/efw/dansguardian/settings") >>> profiles += glob.glob ("%s/*/settings" % "/var/efw/dansguardian/profiles") >>> profiles ['/var/efw/dansguardian/settings', '/var/efw/dansguardian/profiles/content2/settings', '/var/efw/dansguardian/profiles/content3/settings', '/var/efw/dansguardian/profiles/content4/settings', '/var/efw/dansguardian/profiles/content5/settings', '/var/efw/dansguardian/profiles/content6/settings', '/var/efw/dansguardian/profiles/content7/settings', '/var/efw/dansguardian/profiles/content8/settings', '/var/efw/dansguardian/profiles/content9/settings', '/var/efw/dansguardian/profiles/content10/settings', '/var/efw/dansguardian/profiles/content11/settings', '/var/efw/dansguardian/profiles/content12/settings', '/var/efw/dansguardian/profiles/content13/settings', '/var/efw/dansguardian/profiles/content14/settings', '/var/efw/dansguardian/profiles/content15/settings', '/var/efw/dansguardian/profiles/content16/settings'] >>> profiles = sorted(map(lambda p: os.path.dirname(p), profiles)) >>> profiles ['/var/efw/dansguardian', '/var/efw/dansguardian/profiles/content10', '/var/efw/dansguardian/profiles/content11', '/var/efw/dansguardian/profiles/content12', '/var/efw/dansguardian/profiles/content13', '/var/efw/dansguardian/profiles/content14', '/var/efw/dansguardian/profiles/content15', '/var/efw/dansguardian/profiles/content16', '/var/efw/dansguardian/profiles/content2', '/var/efw/dansguardian/profiles/content3', '/var/efw/dansguardian/profiles/content4', '/var/efw/dansguardian/profiles/content5', '/var/efw/dansguardian/profiles/content6', '/var/efw/dansguardian/profiles/content7', '/var/efw/dansguardian/profiles/content8', '/var/efw/dansguardian/profiles/content9'] Discovery. >>> profile = glob.glob ("/var/efw/dansguardian/settings") >>> profiles = glob.glob ("/var/efw/dansguardian/settings") >>> profiles += glob.glob ("%s/*/settings" % "/var/efw/dansguardian/profiles") >>> profiles ['/var/efw/dansguardian/settings', '/var/efw/dansguardian/profiles/content2/settings', '/var/efw/dansguardian/profiles/content3/settings', '/var/efw/dansguardian/profiles/content4/settings', '/var/efw/dansguardian/profiles/content5/settings', '/var/efw/dansguardian/profiles/content6/settings', '/var/efw/dansguardian/profiles/content7/settings', '/var/efw/dansguardian/profiles/content8/settings', '/var/efw/dansguardian/profiles/content9/settings', '/var/efw/dansguardian/profiles/content10/settings', '/var/efw/dansguardian/profiles/content11/settings', '/var/efw/dansguardian/profiles/content12/settings', '/var/efw/dansguardian/profiles/content13/settings', '/var/efw/dansguardian/profiles/content14/settings', '/var/efw/dansguardian/profiles/content15/settings', '/var/efw/dansguardian/profiles/content16/settings'] >>> profiles = map(lambda p: os.path.dirname(p), profiles) >>> profiles ['/var/efw/dansguardian', '/var/efw/dansguardian/profiles/content2', '/var/efw/dansguardian/profiles/content3', '/var/efw/dansguardian/profiles/content4', '/var/efw/dansguardian/profiles/content5', '/var/efw/dansguardian/profiles/content6', '/var/efw/dansguardian/profiles/content7', '/var/efw/dansguardian/profiles/content8', '/var/efw/dansguardian/profiles/content9', '/var/efw/dansguardian/profiles/content10', '/var/efw/dansguardian/profiles/content11', '/var/efw/dansguardian/profiles/content12', '/var/efw/dansguardian/profiles/content13', '/var/efw/dansguardian/profiles/content14', '/var/efw/dansguardian/profiles/content15', '/var/efw/dansguardian/profiles/content16'] >>> OBS.: The glob module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell.
