Ubuntu Multimedia :: Flash Troubleshooting And Optimization ?

Jun 25, 2010

Due to the enormous quantity of flash plugin related problems, I decided to expand my tutorials and create this thread to provide support for flash issues (is getting really hard to follow all the flash related threads and provide a decent support)

Current available tutorials:
Flash Optimization
Flash Issues & Solutions

Firefox extensions:

When asking for support, please describe your problem in detail and provide the output of the following commands and instructions. This will make sure I will have a good understanding of your Firefox and Flash installations, so I don't need to guess what might be happening to your system:

1 - Flash Version

Type about:config in Firefox address bar, then type plugin.expose_full_path in the filter, then double-click the same item in the results to make it true. Then type about:plugins in the address bar, find Shockwave Flash, copy the corresponding Path and Version and paste here. it should look lie the image below:

2 - Firefox version and architecture

To find Firefox version and architecture, click "Help >> About Mozilla Firefox" in the menu. The info will be located at the bottom of the info dialog:

3 - System Info

Execute the following commands then copy the generated file, named firefox-report.txt from your Desktop and upload it here or paste the contents.

Ubuntu Multimedia :: No Flash Audio - Can't Hear Any Sound From Flash Content Displayed In Fire Fox

Sep 26, 2010

I recently installed Ubuntu 10.10 AMD64 beta. After installing the flash player, everything worked fine. I installed a few updates, as well as Ubuntu Stuido from the synaptic package manager, and when I rebooted, I can't hear any sound from flash content displayed in Fire Fox. All other sounds work fine, and I made another user account as a test, and that account has full audio functionality, including flash...

General :: Ubuntu Boot Optimization Strategy And Oddity

Jan 7, 2010

I want to get Ubuntu blazing fast and I started out by changing the swappiness to just 10 and got a huge performance spike. I was very happy with that. Then I used rcconf and GNOME's startup applications GUI and edited out quite a bit but still have a somewhat slow boot. Well, the next thing I thought I should do is edit the inittab and rid my self of some surely unneeded services. Well, according to this website, Ubuntu doesn't use this inittab, but etc/event.d doesn't exist either! Well I looked in /etc for something related to init, and I believe I have found where these services are called upon. /etc/init.d and /etc/init.

Now the files contain many scripts for different services so I was wondering how to edit these to turn them off to optimize my boot! Do I comment out the unneeded ones? My next question is what strategy should I use as I edit these? I think I can get rid of "ssh" and "cups" and "samba" since I don't use these. Can someone point me to a nice list of services and their functions? I just want to optimize Ubuntu as much as possible to not only have a fast computer for my self and family to use, but to impress Windows users with the speed that can be obtained from Linux!

Programming :: Memory Optimization For Child Processes?

Sep 6, 2010

I work on Linux for ARM processor for cable modem. There is a tool that I have written (as the job demands) that sends/storms customized UDP packets using raw sockets. I form the packet from scratch so that we have the flexibility to play with different options. This tool is mainly for stress testing routers.

The details are here.

I actually have multiple interfaces created. Each interface will obtain IP addresses using DHCP. This is done in order to make the modem behave as virtual customer premises equipment (vcpe).

When the system comes up, I start those processes that are asked to. Every process that I start will continuously send packets. So process 0 will send packets using interface 0 and so on. Each of these processes that send packets would allow configuration (change in UDP parameters and other options at run time). Thats the reason I decide to have separate processes.

I start these processes using fork and excec from the provisioning processes of the modem.

The problem now is that each process takes up a lot of memory. Starting just 3 such processes, causes the system to crash and reboot.

I have tried the following:- 1-I have always assumed that pushing more code to the Shared Libraries will help. So when I tried moving many functions into shared library and keeping minimum code in the processes, it made no difference to my surprise.

2-I also removed all arrays and made them use the heap. However it made no difference. This maybe because the processes runs continuously and it makes no difference if it is stack or heap?

3-I suspect the process from I where I call the fork is huge and that is the reason for the processes that I make result being huge. I am not sure how else I could go about. say process A is huge -> I start process B by forking and excec. B inherits A's memory area. So now I do this -> A starts C which inturn starts B will also not help as C still inherits A?. I used vfork as an alternative which did not help either. I do wonder why.

reduce the memory used by each independent child processes.

Server :: Postfix & Anti-spam Optimization

Jun 21, 2011

My postfix server has been working great for the last 1-2 years. Lately the number of spams encreased (from 1-2 every day to aprox 8-10 every day per domain for some domains ).I post here the output of postconf -n. Maybe someone gives me some advices about what cat I change or how can I optimize. I must recognise that I don't fully understand details of how postfix and all the restrictions works together, but I will document every advice.

Programming :: Implementing Search Engine Optimization (SEO)

Mar 31, 2011

Though I have developed some web applications (automation tools) using PHP which have been primarily meant for Intranet (within the organizations I have worked for), I have paid little attention to SEO (it was not required until now). But now I want to understand how do we go about implementing SEO and where do we fit this mechanism in a system / website?

Do we need any other tools or learn some specific programming /scripting language to achieve it?Will implementing a good SEO yield identical results irrespective of what search engine (be it Google or Yahoo!) is being used by users?

Ubuntu Servers :: Fan Control - Power-Noise Optimization On The Proliant DL120 G6 ?

Jul 12, 2011

I'm trying to get the HP Proliant DL120 G6 server a lot quieter after startup under Ubuntu Server 11.04 (x64).

For now, it seems like there is no fan control at all: when I start the server, the fans start running at max speed, then it slightly lowers to 3.5K-5K RPM. Once there, it never goes down or up. There's just no fan or power control at all.

In no specific order, I will describe as much as I can my situation.

The system is IPMI 2.0 compliant, so when using the ipmitool package I can get the values of the sensors like this:

Code:

I tried to follow the procedures for using the fancontrol package together with lm-sensors, as shown at [url]. One of the very first steps is to launch "sensors-detect", which gives:

Fedora Installation :: Partitioning / Mounting Points For SSD Optimization

Feb 23, 2011

I am building a new MiniITX system and partitioning/mounting points for SSD optimization. The majority of / will be on the SSD, but files that are written to often shouldn't be there as the high write operations will diminish the lifetime of the SSD. I will also have a 450G SATAIII drive where I believe that directories like /tmp and /home should be. I also like the idea of a RamDisk for browser/etc files

Intended system:
MoBo: Minix 890GX-USB3
CPU: AMD Phenom II X4 910e Deneb
RAM: G.SKILL 8GB (2 x 4GB) DDR3 1333 (PC3 10666)
HDA: SSD Corsair SATAIII 2.5" 128GB
HDB: Western Digital SATAIII 2.5" 450GB
PSU: Pico 160W PSU
Case: MiniBox M350
OS: Fedora (with Win7 in VM or DualBoot)

Networking :: Local Dns Server Cache Size Optimization

Apr 24, 2011

Does anybody have some thoughts about a local dns server cache size? What is the optimal one? In terms of memory consumption and number of re-enters into the cache. Lets say that default size is 150, so I've change this to 500 and after some time I see 379 re-enters into the cache. Simply put I need to increase the cache size 2 times. But due to the fact that browser preloads dns names it is not possible to interpret the number of overwrites in terms that it is not possible to say if useful cache entries were overwritten or those that the browser precached ( in other words not needed ). In this case it is ok to overwrite unwanted entries because it is not likely that I'll need these entries anyway

I'm running the dnsmasq on an embedded system with limited ram and with an umts dongle attached. It is important to keep the cache size as small as possible to reduce memory usage and at the same time to reduce number of external lookups because dns latency of the umts connection is high (1-2sec for the dns query)

Programming :: BASH Script Optimization For Testing Large Number Of Files

Sep 18, 2010

I want to move files from a $SOURCEDIR to a $DESTBASE/$DESTDIR. Under $DESTBASE there are many directories, and I need to test beforehand if a file from $SOURCEDIR already exists in any of them.

This is obviously extremely slow, and the real use case involves dozens of dirs and thousands of files. Creating a temporary "index" file for the find command (instead of running it every iteration) speeds it up a little, but it's still very clumsy.

Ubuntu Servers :: Apache SSL Configuration Troubleshooting?

Jul 19, 2010

I am trying to configure Apache on my server to work with ssl, but everytime I visit my site, I get the following message in my browser: SSL connection error. Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.

Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. Just some background on the situation: I am using Ubuntu 10.04 desktop edition. I installed apache by installing zend server (it installed apache automatically). I then installed openssl. Non-https pages work fine on the site. I tried getting trial certificates from multiple certificate sites but nothing is working (same error). I was previously hosting my site on another server on which ssl worked just fine. I also tried using the key and crt file from that server, but I got the same error. The domain name and IP are still the same though. My SSLCertificateFile and SSLCertificateKeyFile are pointing to the correct directory and files.

Ubuntu Networking :: Server 10.04 Network Troubleshooting?

Sep 1, 2011

I've got a server that I've been trying to get Ubuntu Server 10.04.01 LTS installed and running on and I've gotten incredibly close to having it work, but the Network is still giving me issues. The installer went off without a hitch (once I fixed some optical drive issues) and it has actually detected the "Intel Corporation 82576 Gigabit Network Connection (rev 01)" Dual-port onboard NIC which shows up when I run lspci. I statically assigned an IP, Subnet, DNS Server and Gateway to eth0 and things looked good. ifconfig showed that it was "UP", and I could ping localhost, but if I tried to ping anything on the LAN it said "Destination Host Unreachable".

Here's the ifconfig and lspci (snippet)

======== ifconfig ========
eth0 Link encap:Ethernet HWaddr 00:25:90:2d:26:98

Server :: Centos 5.5 Box Troubleshooting ?

May 13, 2011

The server is booting up properly and the system is running. When browsing web sites on the sever and they seem to run fine. But when you make requests to it, it seems to take a long time to process stuff. Such as large mysql request. Even to the point it freezes. It seems that if you make a request of some sort it just over loads. I have checked the logs and the most I can get from it that one of my wiki sites that seem to be getting nailed with spam bots trying to getting which is one of the databaes that where repaired could be slowing it down A LOT. Now I did find a couple databases that where marked as crashed and they have been repaired. I am not really sure what is causes the errors since the HD space is fine, ram is fine, internet connection is fine...So I am not familiar with diagnoses linux as much as I am with a windows pc. I am not real shell friendly. I am not good with the basic troubleshooting commands to try and identify the source of the problem to correct it. Could anyone point me the way...

Thanks in advance and I apologize for being a ra-tard on these. I should know this stuff more than I do running a server like this. It was created in 2006 and has been problem free since. Another thing, mass emailing isnt working either. It may be mysqld related. Sorry for the fragments and such. It also seems the SMTP isn't working properly as well suddenly.

Another error I been seeing:

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytesPHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16 bytes some times I see this as a 32 or 64 bytes as well.

FTP Connection: It is also slow when making ftp connects. It is extremly slow but they finally do complete. It can be just a simple connection to display content. Slow.

Ubuntu :: Common Terminal Commands Used For Troubleshooting In The Forums?

Aug 8, 2010

I need to know what commands we have people run in the terminal in order to help them troubleshoot their issue. The reason being, is I was reading a thread where someone was stating about how they had to do all this and all that from a terminal and what not and that there should be a GUI Tool.

Well I'm going to make a GUI tool that allows them to obtain all the necessary information (and fixes are possible too) to help with their issue that they're currently having. For example: I know we run lsmod for sound issues, but what other commands do you have them run to check sound, video, network, etc. It will be made in wxPython so that it can be easily sent to others. If it becomes quite useful, then maybe we could get it in the repos.

Ubuntu Networking :: Mounting / Automounting / Setup Troubleshooting

Jun 18, 2011

I need help to figure out mounting. I have 3 computers running Natty. 1 a desktop 64bit dual boot with Win7 (64) Home Prem; a dell inspiron mini (32bit) dual boot with Win7 Home Prem, and an old 486 Intel based PC running ONLY Ubuntu. My Samba shares are on an external HD currently residing on the 64 bit. I installed Mount Manager...still trying to figure out how it works exactly. I'd like to auto-mount the shares "routinely accessed" (shared network drive, network personal for each machine) allowing as needed access. Then the other personal network drives I would like to mount only when needed. Leaving local home drives password/share protected ... using the network personal folders as a place to add files or such that need to go to a local drive.

{basically I have 3 computers which each have a local home folder, and a network home folder; then I have a network shared share where open shares will be stored (email, calendar, most documents, theetc) each computer has a primary ubuntu user (user id 1000). I have 3 windows ids on 2 computers. each of these ids has been paired with an ubuntu user in smbusers; after this weekend I will only have 1 windows share and 1 user hopefully! so the other two ubuntu users will have non-existent windows IDs}Right now I can (from a non-server machine) access the shared network drive, but cannot access any others. (Makes sense...that share is totally open). On the remote drive I have samba the the installed but no samba directory and it hasn't been configured (obviously).On the standalone (where the HD is attached) I can access any of them by mounting them where they are listed under Places, but through the network menu I can access the shared drive, and the personal drive with just one password entry (my login or sudo password). The others whenever I enter my login/sudo password I get an unable to mount error.

I currently have 3 Ubuntu users & 3 windows users. I've assigned each Ubuntu user an window user name hoping that would make the authorizations easier. I'm currently using a generic Samba password and a generic Ubuntu login password but they are different. So one password for each, each user has the same passwords. I do allow guests using the guest group (not nobody, but I could change that easily enough)If I weren't so stubborn I'd just ditch the passwords, make all shares open to everybody, but eventually I hope to be able to do remote access (via mobile) and would rather just do it all from the beginning than mess with it later.I've been hesitant to mess with programming in the mount/unmount process because I'm not sure I understand it that well (which is why I installed Mount Manager). Problem is I don't understand it well enough to figure out how to use Mount Manager. I did see where automount will not work if you have to authenticate the share before mounting. One of the reasons I only want to automount the 2 shares for each machine. That particular process sounded like what i want for those 2 connections on each. But first I need to figure out mounting period I guess.I may be really confused, or trying to do something that I with my limited knowledge and needs really don't want or need to do....wouldn't be surprising! I'm known to make things more complicated than needed. If a simpler approach seems more logical feel free to share!

Ubuntu Networking :: Wireless Network Connection Troubleshooting

Jul 9, 2011

Just installed ubuntu 11.04 on an old pc. At first, I was unable use my wireless usb adapter (netgear wpn111), but was successful after installing ndiswrapper-common and ndiswrapper-utils-1.9 manually. cool! then I updated all packages successfully via synaptic package manager and rebooted.now I have lost network connectivity. the os still sees the wireless usb adapter, but I have no connectivity. the indicator applet shows an exclamation point.

How can I troubleshoot this? are there logs? can I fallback to a previous good state?I am new to ubuntu, but experienced in unix. note: my pc only has 1/2 GB memory if that matters. but, hey, it worked once.

Debian :: Troubleshooting New Wireless Network?

Aug 16, 2010

I have had no problems connecting to any of my wireless networks in the past. Right now I am at a friend's house and can't get internet access with my laptop. I have entered the appropriate fields in /etc/network/interfaces (as I usually do)

auto wlan0
iface wlan0 inet static
address 192.168.2.64
netmask 255.255.255.0
broadcast 192.168.2.255
gateway 192.168.2.1

I checked this info with the router's web interface and everything seems fit. The network does not have a password. I have tried adding "wpa-ssid belkin5g" and "wireless-ssid belkin54g", and neither one works (can't ping the router after bringing wlan0 down then back up). I have also tried connecting with DHCP instead of setting a static address.
