• ffserver - streaming problem transcodation for input

  - by zozo

  Good day to all. I have a little problem. I'm trying to stream something from a cam to a server and then forward to... somewhere (it will be a site or something). On the computer that I have the cam connected to I use vlc to stream it to the server and there I try to get the stream as an input for a ffserver. The problem is that ffserver doesn't detect the input (regardless of the protocol I use (udp, rtp, etc.)). I suspect a transcoding problem or something like that but I can't find any documentation about that so... Does any1 know what transcodation I should use? Thank you for help and have a great day.

• Rework filename from mod_pagespeed back to normal files

  - by British Sea Turtle

  I am hoping someone can help me with this problem. I am moving to a new server and not using mod_pagespeed any more. However We not that we have lots of external links that link to images on our server using the strange mod_pagespeed filenames. This is not an issue but we do not want to have lots of 404 errors. So I have lots of links like the following : http://www.domain.com/images/150x150xlink.png.pagespeed.ic.pPXw45HSQm.png http://www.domain.com/images/paris_01.gif.pagespeed.ce.vfrkuKUaj0.gif http://www.doamin.com/images/1st2.gif.pagespeed.ce.OUg38q6VbZ.gif How can I redirect them to : http://www.domain.com/images/150x150xlink.png http://www.domain.com/images/paris_01.gif http://www.doamin.com/images/1st2.gif There are thousands of files like this so I am hoping for a simple solution with mod_rewrite, I tried this but it does not work. So any help would be appreciated. RewriteCond %{REQUEST_URI} \.gif\.pagespeed\. [NC] RewriteRule ^(.*?\.gif)\..*\.gif$ $1 [NC,L]

• sendmail: how can I restrict access to clients that only have a valid certificate?

  - by lxg

  I want to reject all connections that don't present a valid SSL/TLS certificate. First of all is the access db file the correct one to be changing? I have already tried using the basic rule given in the documentation CertIssuer:/C=US/ST=California/O=endmail.org/OU=private/CN= Darth+20Mail+20+28Cert+29/[email protected] RELAY This will obviously need a rule afterward to filter and reject all that don't present the cert? Does anyone have any pointers as to what syntax I should use? wildcards? lxg

• smartctl or hddtemp for xvda [on hold]

  - by HST

  I'm trying to check the state of the drives on a remote server running Debian wheezy. I'm using a software RAID10 on top of, I guess, xen, since the entries in /dev are /dev/xvda and /dev/xvdb But it I try smartctl -a /dev/xvda I get /dev/xvda: Unable to detect device type Smartctl: please specify device type with the -d option. I've tried various device type guesses, none work Similar problem with hddtemp, which reports ERROR: /dev/xvda: can't determine bus type (or this bus type is unknown) I've searched the smartmontools documentation, but can't find any discussion of virtual disks. . . How do I get behind the virtualisation to something smart tools or hddtemp can work with?

  - by Donna Crain

  Hi I hope someone can help me... I accidentally renamed my own user name on my mac running OS X 10.4.11 and tried renaming back to what it was but now I have two accounts (the one I want to use which has all my preferences, applications, mail boxes, etc etc) is it possible to copy my settings from my original into this new user name? When I open my computer it defaults to this new account but everything is setting up from new and I just need to get access to all my work documents, mail settings etc. If there is anyone who could help out, I would be very grateful. Thank you in advance.

• How do I fix a corrupt .cab file?

  - by j03lar50n

  In Windows XP, I have a folder of install files- an .exe pointing to 3 Setup.cab files. As the install progresses, it hangs on Setup2.cab as it installs tutorial_page.chm (a Help file). I have 3 options when it hangs: Abort, Retry and Ignore. Both Abort and Ignore rollback the install and exit. But if I keep pressing Retry the install will progress & this action has successfully installed the program (eventually) for me. I AM WONDERING IF I CAN EXTRACTRE-PACKAGE THE .CAB? From the installed program can I grab the help.chm file and replace it into Setup2.cab for a successful install? I am aware of the Microsoft Cabinet Software Development Kit http://support.microsoft.com/kb/310618 and How To Manually Modify and Rebuild CAB Files http://support.microsoft.com/kb/176810 but 1.)want to ask if this is even possible & 2.)don't know how to make a .DDF file for Makecab.exe

• Can't Launch Firefox on OS X 10.6

  - by user61804

  When I try to run Firefox 3.6 or 4 beta I get a message saying: Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible. I have tried running the profile manger from the command line using: /Applications/Firefox.app/Contents/MacOS/firefox-bin -ProfileManager I get the same message in the popup, but I also get: Error: Access was denied while trying to open files in your profile directory. I have tried deleting firefox and reinstalling it. I have also tried deleting anything related to Firefox or Mozilla in the ~/Library/Application Support directories, but nothing seems to help. In addition I have run the disk utility to fix any permissions issues. If I create a new profile or run the command with sudo it works. It seem that that Firefox is trying to put the profile somewhere it doesn't have access to write, but I can't figure out how to change this location or change the permissions. Any help would be greatly appreciated.

• What happens when Oracle's Enterprise Single-Sign-On database goes down? [migrated]

  - by Unai

  We're working on setting up Oracle's Enterprise Single-Sign-On with High Availability. At the moment every component provides HA except our database backend (i.e. we have just one instance). While conducting some kick-the-plug tests we learnt that the ESSO system works even with the database turned OFF. This was a nice surprise but now we need to understand what are the implications of a database failure; sure the sessions might be handled on the application servers and the policies might have been cached but... for how long? how big is this cache? what is the role of the database? I would appreciate if anyone shares her/his experience and/or points out to documentation that covers this. Thank you so much.

• Installing Windows 7 on a BSOD Windows Vista (ASAP)

  - by anonymous

  On a previous question i posted, i asked for help on fixing my windows vista box because it keeps going to blue screen. No one seems to have the answer, so now i want to install Windows 7. I want to know if i can install 7 without having to reformat my hard drive and having to lose all my files. I've already confirmed the hardware is working because i installed Ubuntu 9.10 on my external hard drive and it runs on my system fine. I tested the memory using vista's memory test and Ubuntu's memory test. here's the previous post: http://superuser.com/questions/125897/i-really-need-help-resolving-a-window-vista-bsod-blue-screen-crash-on-my-deskto

• Virtual machine won't connect to networking interface

  - by Keyo

  I have moved my virtual box hard drive (.vdi file) from windows7 on a laptop, to windows7 on a desktop. No big deal I thought. The OS is ubuntu 10.10. Now networking is broken. I don't have a solid understanding of windows networking, maybe someone can help. Anyway, the networking no longer works. I've tried to setup eth0. I have virtualbox setup in bridge mode, my wifi connection on windows to an intel card on the virtualbox side. I think it might be something to do with windows not allowing the connection to bridge properly (security issues). I've provided some screenshots, which will hopefully help.

• How do I send email in plain text rather than HTML in my email client?

  - by JS Bangs

  For various reasons, I often have to help friends and family to send email in plain text rather than HTML. However, many of them use email clients that I'm not familiar with, forcing me to search the internet, read help files, or click randomly through dialogs looking for the setting. I've often wished there was a single page that included instructions for changing this setting for every popular email client. So let's make one. Write instructions for changing email settings from plain text to HTML in your preferred email client below. If someone else has already done so, please upvote their description so that the most used email clients rise to the top. (For obvious reasons, there won't be an "accepted answer" for this question. I'll set this question to community wiki after a few days.)

• MIDI Over Networking on OSX: Lots of beachballing

  - by Yar

  I have 4 computers connected to a Wifi router (with no Internet uplink). Whenever we enter the Network interface for Audio/Midi preferences in ANY of the computers, the Mac beachballs and then finally finds its way. Occasionally, however, one of the computers fails to receive the MIDI information that was destined for it via the Network MIDI interface. Changing to all wired connections does NOT help. Adding Internet uplink DOES help and the problem is resolved. This makes no sense to me as the computers can access each other just fine with or without the Internet uplink. Any ideas? [NOTE: I'll update the question if people correct my terminology, or feel free to do that if you have the rights].

• Setting Up an IP Camera in ZoneMinder from Ubuntu

  - by Chris S

  I recently bought a TV-IP312W wireless IP camera. I've completed the basic setup on the camera itself, and confirmed I can stream video using the utility CamViewer. Now I'm trying to access the camera from ZoneMinder, so I can setup monitors and alerts. However, I'm finding the documentation a bit laking. Following the tutorial and a forum post, I've install ZoneMinder, and can access the web interface, but I'm getting stuck at the "Check that your Camera Works!" section. I can add a monitor, but after I add the configuration: Source Type: FFMPEG Source Path: http://192.168.1.105/cgi/mjpg/mjpeg.cgi?.mjpeg all I get is a broken image. What am I doing wrong?

• IMAP can't access virtual account sharing name with local user account

  - by chernevik

  I am setting up a postfix/dovecot mail server with virtual accounts, per the Chris Haas tutorial. I'm finding that virtual users who also have local user accounts on the mail server cannot access their email remotely via IMAP. They're told they cannot login. (I'm using Thunderbird for that). These same users can login when emulating IMAP locally via telnet. Virtual users without local accounts have no trouble with IMAP access from remote clients. These local user accounts have vestiges of prior efforts in their home directories: mbox files, Mail and mail directories. I've looked at the logs for clues to where the remote login process is failing (dovecot authentication failure? confusion over where emails are stored?) but found nothing helpful. I haven't found much in the dovecot or postfix documentation that describes the IMAP login process and expectations in enough detail to help me diagnose this. So: how do I go about identifying the problem and researching a solution?

• grub error: symbol 'grub_puts_' not found

  - by ladaghini

  I updated from Ubuntu 9.10 to 10.04, and after installation, the computer restarted. When grub loaded, all I get is a screen that says error: symbol 'grub_puts' not found and a useless grub prompt that looks like grub_rescue I've tried reinstalling grub from the livecd (usb drive) following this guide: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows to no avail. Sometimes, when I start up from the live usb, linux doesn't recognize the harddrive at all. It's not in the places menu, nor does fdisk list anything. If anyone can help fix up grub so it recognizes and boots up the two os's I have installed, I'd appreciate it. Also, I know little about grub, so try and make it easy to understand.

• How do you confirm network adapter is gigabit capable?

  - by StrandedPirate

  Upgrading my network to gigabit speeds and don't know how to determine if the NIC in one of the systems is capable of gigabit speed. The documentation from the manufacturer states this: Network adapter 10/100/1000 Ethernet LAN on system board However when I go to the properties of the NIC under Speed & Duplex my only options are: 10 Mb Full 10 Mb Half 100 Mb Full 100 Mb Half Auto Is there a command line I can run that will give me more detail about the NIC? Windows 7 x64 OS New Info: The new switch I just bought has a light to indicate 1000Mbps. I can tell from the light that this NIC is indeed negotiating at 1000Mbps but I'd still like to know how to determine this from the console in windows.

• Adding a single 300Gb SCSI drive to poweredge 2850

  - by John Steele

  I have a 2850 setup with 3 146Gb drives, two partitions 1 12GB system with server 2003 sp2 and 1 261Gb Data. I am strapped on disk space on the data partition having to push data around. I wanted to add a 300Gb single drive for lesser critical data, is this possible? Or is it best to add 2 300Gb drives for another RAID 1 configuration? This is my church network and while it is mission critical it is not enterprise so I can take it down for a few hours. Any pointers to documentation or direct help would be greatly appreciated. John

• Text Editor that hilights all instances of selection for Mac

  - by jedierikb

  On Windows, I use Notepad++ which has the great feature of when I select a word, all instances of that word are also highlighted in the same document. I have found it very helpful for finding patterns in giant log files. I am wondering if there is a similar feature in a text editor on the Mac. I have looked into the documentation for TextWrangler and TextMate to no avail. Hopefully there is a way to do this so I can be more productive when working on a Mac. -- Note: in Notepad++ you do not have to do a keyboard shortcut to make this work... you just select some text and it does the highlighting for you automatically.

• How to avoid tilde ~ in Bash prompt?

  - by Jirka

  Hello! I have set my prompt in bash in a such way that I can use it directly in scp command: My current PS1 string: PS1="\h:\w\n$" And the prompt looks like this: lnx-hladky:/tmp/plugtmp $ What I don't like at all is the fact that $HOME directory is displayed as tilde. Can this be avoided? It's causing problems when switching between different users. Example: lnx-hladky:~/DOC $ Documentation says: \w : the current working directory, with $HOME abbreviated with a tilde \W: the basename of the current working directory, with $HOME abbreviated with a tilde Is there any possibility to avoid $HOME being abbreviated with a tilde? I have found one way around but I feel like it's overcomplicated: PROMPT_COMMAND='echo -ne "\e[4;35m$(date +%T)\e[24m$(whoami)@$(hostname):$(pwd)\e[m\n"' PS1=$ Can anyone propose a better solution? I have a feeling it's not quite OK to run so many commands just to get prompt. (date,whoami,hostname,pwd). Thanks a lot! Jirka

• Ubuntu 10.04 install - frozen at splash, no errors

  - by Andrew Bolster

  Has anyone else come across this? After about as much of a fresh install as i can muster without buying new drives, and after walking through the amd64 alternate install with ease, and after a little 'pre-splash' screen where the orange dots under the (very sexy) new ubuntu logo blink away, I'm left with a vista of purple hues and logo plonked in the middle, with the dots not going anywhere. I was at this same position last night at 3 in the morning, left it lying overnight, and nothing had changed, so I'm pretty sure its frozen, but when i go in and inspect /var/log/* in the recovery console, no errors, no complaints, no problems. I'm at my wits end and am just about ready to try anything. If this was on SO I'd be bountying, but if anyone can help you'll just have to cope with my thanks! Additional Details on my blog and my first attempt at asking for help

• Directly editing IIS 7 applicationHost.config configuration file

  - by lunadesign

  I know that IIS 7+ now uses XML config files instead of the metabase. I also know that if I edit a web.config file for a given site, IIS automagically detects the changes and implements any corresponding config changes. However, does this also apply to the server-level applicationHost.config settings file? (Its usually located in C:\windows\system32\inetsrv\config.) Specifically, is it safe to carefully edit this file instead of using IIS Manager or the appcmd command line utility? I couldn't find anything in the documentation that said it was okay or not okay to do this. I'm curious because I have to change the bindings for numerous sites from one IP to another. It would be much faster to simply do a global search and replace for the IP address in the config file instead of manually editing a few dozen sites in the GUI.

• Have VIM jump to a ctag in an existing tab

  - by Adrian Petrescu

  I have ctags configured with my vim installation. My habit is to usually have all of the relevant files I'm working on open in tabs in vim all at once. The "problem" is that if I use Ctrl+] to jump to a ctag in a file I'm editing, it will replace the buffer in that tab, even though I have another tab already open containing that symbol. It would be much better if it just switched to that tab and jumped to the symbol there instead. This way I would always have a 1-to-1 tab-to-file ratio. I noticed in the Changenotes for the taglist.vim plugin (which I also use) has an entry that says 1. Added support for jumping to a tag/file in a new or existing tab from the taglist window (works only with Vim7 and above). However, I couldn't find anything in the documentation for Taglist (or Ctags) about how to actually do this. Can any vim gurus fill me in? Thanks!
