I want to write a program to filter web content. I believe that i can write a filter program by usig java however problem is that how can i place this program like "internet -> filter -> web browser" ?
View 4 RepliesWe have approximately 100 retail locations that will have split vpn tunneling. Intranet traffic will flow over the vpn to the corporate headquarters, voip traffic will tunnel to a regional hub and internet bound traffic will go over the local isp. The retail locations are small with 1-8 users and no enterprise grade equipment (servers, etc). This setup in effect will render our current content filtering solution useless.
The locations will be equipped with Cisco ASA 5505 Firewalls. The original plan was to use a Websense server and the url filtering feature to act as a content filter. I just found out that pricing for Websense was not included in the budget will be a show stopper.There may also be some performance issues with this method. Putting a proxy server at each location is not really an option. We do not have the resources to place a server at each location, plus the users could simply unplug an inline device or go around it. There is minimal supervision at most of these locations.
Ideally, I would like to find a way to use something like Dansguardian with an ldap interface and the url filtering feature of the ASA firewalls. I found a program called n2h2p, but I can find 0 documentation for it. It is also 2 years old with no updates. I also need to be able totrally manage this as trying to keep up with 100 different configurations for 400 users would be virtually impossible for the amount of time I will have available
I have the following command that I run on cygwin:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv
I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each
/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties
so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:
/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>
and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv
I have been assigned a task to implement a free open source content filter having feature of web, email, instant messaging etc. If any one has the information or worked on this type of product please share it.
View 8 Replies View RelatedI want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.
1. If the To Header contains "support@thisdomain" then run a program.
What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.
2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.
3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.
last friday my schools isp enabled iwsva - interscan web security virtual appliance from trendmicro. all traffic is now filtered, and slowed down. videos and other videostreams are now useless. after this we have had serious problems using our netbooks with ubuntu, and upgrading workstations with ubuntu has become very problematic, or almost impossible. i have to run the update process 6-8 times before all packages are updated.
what can i do to document the problem in a good way. the isp tells me that there are no problems, and that it has to be a linux problem. (ever heard that one before?) the ltsp-clients on my debian servers does not have the same problems, maybe because they are using the proxy on this server?
How can I make radiolist dialog which content so many options what is the value of the variable?Quote:

dialog --title "sdf" --backtitle "sdff" --radiolist "ffdsfsd" 15 60 5 "1" "first" on "2" "second" off "3" "third" off "4" "fourth" off etc..
I must explode dialog in loop and add options? or something like that?
I set up Evolution with a gmail account using TLS both for sending and receiving messages. Then I markd Inbox and All mail folders to be synced for offline usage from their properties (right-click folder and select Properties item).I tried File>Download Messages for Offline Usage and Send/Receive button and Work Offline / Work Online and pressing sync for offline usage when it asks before going offline. But in all situations, Evolution ONLY shows messages (at its status-bar area) about syncing messages, checking for new mail, etc. but DOES NOTHING without any real network activity. Time to time it sends receive some kilobytes, but I could not make it to start some gigabyte gmail syncing transfer.

View 5 Replies View RelatedIt seems that rpm in CentOS has a filter to change the phrase "Red Hat" to CentOS
I understand why such a filter exists - but here's the problem -
From the EPEL rhnlib package, when viewing with rpm -qi -
Description : rhnlib is a collection of python modules used by the CentOS Network [url] software.
That gives an incorrect impression that [url] is a CentOS web site.
Package - rhnlib-2.5.10-1.el5 from EPEL
If you download the src.rpm from EPEL and view it with rpm -qip you get the filtered description, but when you install the src.rpm and look at the spec file, it clearly says CentOS.
I think you meant Red Hat. - pschaff
Perhaps instead of filtering the displayed meta data, the CentOS build system could do the filtering before the spec is built?
That way packages that are not built by CentOS will not be impacted, and cases in CentOS where the filter isn't appropriate could be handled by a list of package names that shouldn't be filtered.
Should I file this as a bug with rpm or is this sufficient?
I'm a KDE fan, but I installed GNOME 3 to give it a test drive. I like some aspects, but I don't care for all the clutter in the menu, in the form of KDE apps that duplicate the functions of native GNOME apps. So I just opened alacarte and un-checked all those KDE apps. Simple, cleaned up the menu beautifully. Then I booted into my main environment, right-clicked on my launcher to open its editor and delete the GNOME apps. All of my KDE apps were gone!
Deleting GNOME apps from KDE works fine: They stay gone in KDE but they're still present in GNOME. The reverse is not true. Is there a better way than what I tried? Besides installing a GNOME distro in a vbox; I tried that and found it too sluggish. I could also replicate a menu structure on a dock (Cairo), but I thought I'd check with the experts first in case there's a less clunky approach.
I wonder how I can filter the syslog? i.e. there is a message that I don't want to see logged in there etc?

View 5 Replies View RelatedI am new to Ubuntu and would very much appreciate someone's assistance in getting my printer to work in the Ubuntu O.S.The printer filter is located in my /home/ldavis/opt... directory and not in the/opt/ OpenPrinting- Epson/ppds/Epson directory where some of the .ppd.gz are located and where the error message states it is looking for it.

We use powerpath on RHEL servers, with at least 2 paths to each disk, as you know the powerpath creates a pseudo devices called emcpowerX. I was wondering if there is any overhead if we don't use the lvm.conf to filter out all sdX disks? Except the "duplicate PV found" messages on LVM, does it delays the boot of the server?

Can i have both servers in the same box without interferring each other?
I have a very simple set up.With Network Manager I can have my laptop act as a router (sharing all connections).I also have apt-cacher-ng as a debian package cacher.I would like to set up iptables to filter only the urls that are meant for a debian package cacher.
For example:I could use a "forward all" rule:
Code:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3142
Except then I would get a bunch of error pages every time I tried to do normal navigating.My question (again) is: Can iptables handle forwarding only on a specific url? If so how?Or is there another solution? (prferably without full fledged software like squid)

How can I filter ASCII quotes( ' ) and double quotes ( " ) so that I can replace them with the UTF-8 equivalent?If I copy text from a Word Document(ASCII), and upload it to a web page with PHP. The Database(UTF-8) will replace these racters with incorrect character(s).I need some function that will replace these characters but I don't know how to differentiate the ASCII quotes and the UTF-8 Quotes without (somehow) converting the string to hex, then preg_replace'ing the hex code for the symbol.
