Mar 24, 2010I currently have two internet interfaces installed, one is ethernet (eth0) and the second is wireless (wlan0). Many command line applications allow you to specify which interface should be used, but many gui apps don't provide this option or at least I haven't found it. I have some questions:
1. How would I tell Firefox to use only my wlan0 interface? If it's possible in Firefox, is this also possible with Google Chrome?
2. If a program doesn't provide a command line argument to support this, is there a standalone application that could help manage preferences for multiple applications?
Ubuntu :: Error: Allowed Memory Size Of 20971520 Bytes Exhausted (tried To Allocate 7680 Bytes) In /var/www/index.php On Line 2
Jan 9, 2011I recently had to move to a new machine, everything went well except for one thing. I did fresh installation of LAMP server all with default configs. Every time I'm using PHP script to that invokes include, require or require_once I get the following error:
Code: Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 7680 bytes) in /var/www/index.php on line 2 index.php file: PHP Code:

PHP Code:

My memory_limit in php.ini is set to 20M. I tried to increase that however it didn't quite work. PHP seems to allocate all possible space and return that message every time i try. If somebody has an idea of how to fix it I would be more than grateful. I spend quite a long time searching for an answer however the all things i found suggested increating memory_limit which in this case doesn't work.

Ubuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?
Jun 9, 2010my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Server :: Sendmail: Block Specific Sender To Specific Recipient?
Oct 1, 2009I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.
View 6 Replies View RelatedNetworking :: Network Usage Is Overloading CPU
May 23, 2009recently my server become a little slow and lazy, so I started a small investigation what's going on and found out, that there is some problem with network.All processes which uses network are able to use 99% of CPU time when they got any requests. First time i thought it's only a bad configured Apache but after some research I found even FTP or SSH does it if they have to do something more (for example getting data to another server using rsync).So far I wasn't able to find a cause of this. No new software installed, only updated every few days. I have another server which have the same config, same software, same hardware and is updated in same days. But this one works without any problem. I think it's probably hardware (LAN) leaving me to it's creator. Is there some way how can I test if it's really LAN or just something bad happened to the system?
Also there is another issue - maximum speed dropped down to 20-30kB/s for both download or upload.It's Debian Lenny 2.6.22-6 if you need to know.

View 2 Replies View RelatedUbuntu Networking :: Monitoring Bandwidth Usage On Lan?
Jul 6, 2011Since this is my number 1 place for asking questions, I figured I would go here first. So I live in New Zealand where good internet doesn't exist yet, and I'm in a flat with 3 other people and we get 40gb a month which hasn't been lasting more than 2 weeks. It is somewhat of a mystery where all our data has gone, so I need a way to monitor usage. We use a variety of operating systems including linux, xp & windows 7 on my pc, and xbox 360. Is there any kind of integrated solution I can use to monitor everything with password protection so it can't be disabled? I have tried looking in the router, but it doesn't give me many statistics, and I think it combines lan with wan usage. At this stage I don't have the money to make a linux box to put between the router and the switch that can monitor everything, but if it comes to it, I will shell out for one.

View 2 Replies View RelatedNetworking :: Displaying Network Usage Stats
Jul 13, 2010A small "mom and pop" WISP would like to provide account usage information to customers.Basically, when a person connecting to the WISP's web site is a customer with an IP address from within the WISP's subnets, a link would appear on the web page where customers could read total bandwidth usage (daily, weekly, monthly, and yearly totals and averages) and public IP address. Information could include the top five bandwidth URLs visited; graphs or charts of usage; and usage during specific periods, such as business hours (8AM-5PM), evening hours (5PM-10PM), night (10PM-8AM), and weekends (10PM Friday-8AM Monday).
The WISP has installed cricket (http://cricket.sourceforge.net) and rrdtool (http://oss.oetiker.ch/rrdtool). The next trick is to grab and format the data for customers.I'm not looking for answers like "look at xyz package." Helpful responses will include a rudimentary outline to solve the problem. That is, "xyz package" might indeed be what the WISP needs, but some guidance how to use xyz is needed to move down the road.I have no experience with this type of thing. I appreciate responses from people who are experienced.
Networking :: High CPU Usage For 100Mbit / S Transfer?
Jul 12, 2010I'm diagnosing why my application is slow and I found the problem by writing a simple TCP client/server, where each side sends/receives 64k at a time. The bottleneck is on the receiving end, which uses has a Realtek 8139 100Mbit/s NIC and running Windows 7. I'm able to get 11.9 MiB/s as expected, but the CPU usage is very high - 80% on 0th CPU and ~20% on 1st CPU. Task manager shows conhost.exe taking 25% CPU and 10% for my program.
When I try the same receiving program on Debian, I can still get 11.9 MiB/s, but the CPU usage is now only 1% (user & system). On the sending side, the CPU usage is practically 0% in both Windows 7 and Debian.
I tried changing the TCP receive/send buffer sizes and disabled internet connection sharing (does extra packet processing?) on the receiving end,
Networking :: Monitoring Home Network Usage
Jul 13, 2010I was wondering how do you slap a packet analyzer like Wireshark somewhere between all the computers in a house and the router, so you can tell what websites are being accessed? I mean websites, specifically. I'm not trying to monitor bittorrent, IRC or other things yet - I'll get to that later. I just want to break this insanely complex task into smaller bites for now.Also, since my ISP has bandwidth caps but does not have a means for consumers to monitor total network usage, I'd like to figure out how to use Wireshark to do that as well. This, I am assuming, is easier when wireshark is running on the pipeline going into the router.
