One of the managers asked me for help to block some web sites were some students in the other lab and people that helps there waste bandwithd seeing videos, movies (youtube, cuevana, serieid, etc) and spend lot of time on facebook also. This is a network issue. You can try to detect a client using too much bandwith for a period of time, and then throttle them. Dropping tcp packets will force throttling. Blocking websites is more effective at a firewall than a desktop. with a few that are seeing movies and videos the rest of us can not work at all. Thing is that other manager (you know how those things are sometimes) do not want us to do that since his guru and expert is the one that controls all the Network. So the best we could get until now is that we can do all we can without touching the Cisco routers and until now not administrative password for change anything on the PCs (that could change one we prove that we can have the solution and show it to the board of people that runs the place). They're asking you to fix a network problem but refuse to give you control of the network. Ask the administrators what happens if all the software you've installed is bypassed by someone bringing in a laptop, or you switch to WiFi and everyone's on a cell phone you done control. Deal with the problem at the network. The Internet provider gives the DNS servers to use and one of the routers gives the DHCP service. First thing I thought was to change the DNS servers and use the one from my small office (running Freebsd 7.3) using Bind there and simply block there pointing the sites to nothing in the Apache configuration. It does not work. Once changed the DNS values the PC does not resolve anything. It was a quick test but that does not work. Not sure if Internet provider is blocking in some way that we can not use other DNS server but theirs. Google is 8.8.8.8 and 8.8.4.4, easy enough to remember, and circumvent. Other solution I was thinking while coming home was to convert one machine there to a freebsd server and use it as a router (if they let me) so that way I can control from there and do filtering. Issue is that maybe they do not let me but connect the server as an extra machine without replacing the main router so in that case I would have 2 DHCP servers doing the same service in the same lan and could be conflicts I guess. That's affecting the network and causing a mess for no good reason. Another solution a friend suggested was to buy one small router (from my money for sure) and let that small router to receive the internet (RJ45) and from that with the small 4 port switch included to provide the internet to the switches to feed the labs , library and administrative offices. I have never use one of those and I am short on money so I would like to explore other alternatives before if possible. Adding a router won't help for the real problem. Finally another solution would be to install in each PC a kind of Nanny software but only if free, otherwise is not a solution (I do not know of any yet but will do searching the following hours). And then you have to trust the software. Some software will ban health information, such as breast cancer, but because of so many porn websites created so fast they can still allow porn. In any case, it's just a firewall. I know all can be solved if the guru-expert guy would let me have passwords from PC's, router, etc but that won't be an option since they think we would try to take the control of those services (we do not want that) so the burocracy could be a problem there. He have told them that to block is not possible (they have been working that way for years). The block is possible, but it's a network issue, the other guy. Either he does it, or you take over the network. The more centralized and built into the network it is, the more effective it is. So, in this kind of schema. Do you think FreeBSD (even linux) could be of help if we do not have access to routers, switches and can not install new software on the PCs( the ones running XP)? No. You lack the network control to control student's computer use. Any comments you have that could help me to solve this challenge? Thanks in advance for your time and comments.

Re: cups slow when printing from firefox
Hi all, I'm struggling with a speed issue when trying to print stuff from firefox (10.0.2,1). I've set up cups (meta package 1.5.2) on my box which uses a Lexmark E360dn printer via ethernet. The printer has a postscript emulation which is set as the default (as opposed to PCL). I've used a PPD file from openprinting.org which claims that the printer is 100% supported. Printing works fine in general with all sorts of text and images, including PDF and LibreOffice and whatnot. However, trying to print maps from maps.google.de sends one CPU to 100% for a couple of minutes. Printing the same map from a Debian box takes a couple of seconds. I can print the map to a file, and print that file with lpr which also takes just a few seconds. While printing from firefox directly, I noticed a process gsc owned by cups which causes most of the CPU load. I take this as an indication that the postscript output from firefox is incorrectly rasterized on my box, instead of sending the postscript data directly to the printer. I did not make any changes to the default config files except for adding the printer through the localhost:631 interface. Is there anything else that I need to configure, either on the firefox or the cups end, to make printing maps faster? regards Markus -- Markus Hoenicka http://www.mhoenicka.de AQ score 38 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org Hi Markus.

It can be due to various different reasons. At a guess, probably this: https://issues.apache.org/bugzilla/show_bug.cgi?id=10712 In which case, it's probably your users getting frustrated with slow downloads and cancelling requests -- improving performance and getting more downstream bandwidth would help. Beyond that, it can be due to apache running out of file descriptors -- you'ld see error messages mentioning file descriptors elsewhere in the apache logs in that case, and it would only appear if your apache setup had hundreds of virtual hosts each with their own log files. Other things to look at: use of EnableSendFile or EnableMMAP in your configuration. IIRC this is generally fine and enabled by default on FreeBSD, *except* when you mount your document root by NFS.

Using kqueue with 2 threads
Hi,
I'm trying to use a kqueue to listen for VNODE events on a worker thread. I
want new events to be registered with the kqueue by a separate thread.
I have been referring to this example [URL=
http://doc.geoffgarside.co.uk/kqueue/file.html;]
http://doc.geoffgarside.co.uk/kqueue/file.html[/URL]
Here are the relevant parts of code as it is at the moment.
In my worker thread:
[CODE]std::cerr Started worker std::endl;
struct kevent ke;
int i;
while ( !mStopRequested ) {
memset(ke, 0x00, sizeof(kevent));
i = kevent(kq, NULL, 0, ke, 1, NULL);
if ( i == -1 ) {
std::cerr kqueue produced error: strerror(i)
std::endl;
continue; // todo is this the best thing todo?
}
std::cerr Beep: i std::endl;
}
std::cerr Shutting down worker std::endl;[/CODE]
Other thread
[CODE]int fd = open(fileName.c_str(), O_RDONLY);
if ( fd == -1 ) {
std::cerr Failed to open file: fileName Error:
strerror(errno) std::endl;
// todo throw exception
}
struct kevent ke;
EV_SET(ke, fd, EVFILT_VNODE, EV_ADD, NOTE_DELETE | NOTE_RENAME |
NOTE_EXTEND, 0, NULL);
if (kevent(kq, ke, 1, NULL, 0, NULL) == -1) {
std::cerr kevent produced error: strerror(errno)
std::endl;
}[/CODE]
When I run my code the kevent call in the worker code doesn't block at all.
Any ideas what I'm missing? or if what I want to do is even possible?
Ben

Do you happen to know of a PCMCIA Type II wireless adapter that is currently being sold online that supports WPA under freebsd 9.0? Alternately, a USB 1.0 adapter? I would rather keep the USB ports free for other uses.

Hi,
I'm trying to use a kqueue to listen for VNODE events on a worker thread.
I want new events to be registered with the kqueue by a separate thread.
I have been referring to this example [URL=
http://doc.geoffgarside.co.uk/kqueue/file.html;]
http://doc.geoffgarside.co.uk/kqueue/file.html[/URL]
Here are the relevant parts of code as it is at the moment.
In my worker thread:
[CODE]std::cerr Started worker std::endl;
struct kevent ke;
int i;
while ( !mStopRequested ) {
memset(ke, 0x00, sizeof(kevent));
i = kevent(kq, NULL, 0, ke, 1, NULL);
if ( i == -1 ) {
std::cerr kqueue produced error: strerror(i)
std::endl;
continue; // todo is this the best thing todo?
}
std::cerr Beep: i std::endl;
}
std::cerr Shutting down worker std::endl;[/CODE]
Other thread
[CODE]int fd = open(fileName.c_str(), O_RDONLY);
if ( fd == -1 ) {
std::cerr Failed to open file: fileName Error:
strerror(errno) std::endl;
// todo throw exception
}
struct kevent ke;
EV_SET(ke, fd, EVFILT_VNODE, EV_ADD, NOTE_DELETE | NOTE_RENAME |
NOTE_EXTEND, 0, NULL);

Re: cups slow when printing from firefox
Leslie Jensen writes: Hi Markus. If you do a search in the archives you'll see that some of us have printing problems with Firefox. Some even suspect that printing in Firefox is broken. I myself has not been able to solve my specific printing problems which include both Firefox but also Libre office. I'm running Win7 in Virtualbox in order to fix my printing :-( Hi Leslie, good to know, I thought it's just me being too stupid to press the right button. For the time being I'll resort to printing to a file and sending that to lpr, instead of running Win7. regards, Markus -- Markus Hoenicka http://www.mhoenicka.de AQ score 38 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The bwi/bwn man pages say the version 3 of the adapter is supported. Amazon doesn't say what version. Is the malo driver for newer versions of the adapter? Thanks to the other poster for suggesting looking at the bwi/bmn man pages.
