• How to convert poor quality bitmap image to vector?

  - by Macha

  I'm designing a website for a group which has lost the original digital image for their logo. The only file they have of it is a jpg which was embedded into a word document. The image has everything possible wrong with it: Anti-aliased onto a white background where it should be transparent Image artefacts Resized downwards poorly. Lines that should be straight and solid aren't. I've currently used the wand tool to get rid of the white background, and stuck it on the website, but it's poor quality makes it stick out like a sore thumb. I need a few different sizes of it to use, so how would I go about creating a vector image based on it?

• Driver problems with rerunning WIM capture

  - by Tim Brigham

  How do I handle driver problems associated with creating a new WIM file using a previously created image as a base? I am using a custom MDT image which installs Windows 7, Office 2010, etc which was created from a previously deployed base image of Windows 7 + SP 1 + updates. When the driver injection is enabled I receive a group of messages (collected from different logs, screens, etc). If I turn the preinstall driver injection off things work as expected. If I leave it on I receive the following messages. windows cannot install required files 0x80004005 8004004 non zero return code ltiapply rc=31 Unhandled error returned by LTIApply: a device attached to the system is not functioning.

• MPEG2-TS streaming: UDP or RTP?

  - by Juan Jose Polanco Arias

  Hello I'm working on an IPTV streaming server in Linux (Ubuntu Server 12.04 LTS) that has a DVB-S/S2 card to obtain satellite channels. Then with MuMuDVB I map all channels in the transponder to a multicast group, for multicast transmission. Now for the MuMuDVB software I can either use UDP for transmission or I can add the RTP header. I was wondering what would be the most convenient for MPEG2-TS because I've heard that RTP is used primarily for MPEG4, but It's also said that RTP can be used for MPEG2-TS. Thanks for your help.

• Configuring vsftpd with nginx on ubuntu

  - by arby

  I have vsftpd installed on Ubuntu 12.04LTS along with nginx, php, and sql on an Amazon ec2 instance. The web server is good to go, but I'm having trouble connecting to the FTP server. I'm not quite sure how to set the privileges or what configuration options I might be missing. By default, the location of the web root is at /usr/share/nginx/www and it is owned by root:root. The web server runs as user www-data in the group www-data. I've opened port 21 and set the passive ports in the ec2 backend and ufw firewall. In vsftpd.conf, I have: ... anonymous_enable=NO local_enable=YES local_umask=0027 chroot_local_user=YES pasv_enable=YES pas_max_port=12100 pasv_min_port=12000 port_enable=YES ... Now, I'm unsure how to create the FTP user that when I login, displays my web directory with write access. I've tried it a few different ways, but I keep running into errors (either no connection, no write access, or very slow timeouts.)

• Excel 2010 Move data from multiple columns/rows to single row

  - by frustrated529

  So frustrating! I get data sent to me and it looks like this: a 1 a 2 2 a 3 3 b 1 b 2 2 b 3 3 b 4 4 b 5 5 b 6 6 and I need it to look like this: a 1 2 2 3 3 b 1 2 2 3 3 4 4 5 5 6 6 I have about 30 columns that need to move to the top value in their group, then removing the duplicates (to which there are about 33 rows of duplicates, trying to get it down to about 8 rows). I have been searching forums for several days and trying bits and pieces of code. I am having such a tough time with VBA!!!! Same illustration, but graphically:     →

• MongoDB on FreeBSD

  - by Hartator

  We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions!

• Outlook 2010 exchange setup prompts for [email protected] rather than [email protected]

  - by Force Flow

  We use a hosted exchange service. When users want to set up Outlook 2010 to access their account, they open Outlook and run through the configuration steps. Autodiscover is enabled, and in the user's active directory profile, their email address is in the email field. However, when the configuration process reaches a point where they are prompted for their email account's username and password, their active directory username is filled in by default instead of their email address. Is there a way to fix that? Users get confused and try to enter their email password over and over again and wonder why it doesn't work (and completely miss/ignore the "use another account" button even though they have instructions right in front of them). I'm also using the Office 2010 ADM's in group policy, but I haven't yet seen an option to specify what gets auto-populated in that windows security prompt.

• Best practice Raid groups for EqualLogic PS6510X

  - by 20th Century Boy

  We are thinking about purchasing 4 x EqualLogic PS6510X SANs (the Sumo boxes). Each has 48 x 600GB 10k SAS drives. They will be stacked to form a logical pool of storage (all in the same location). I understand that when you create a RAID group its done on a "per box" basis. So one box could be Raid 50, another Raid 10 etc. My question is, should I make one box a "performance" box ie Raid 10, and the other boxes "standard" ie Raid50? How do people configure their EQL arrays in the real world?

• Hyper-V Server hvremote.wsf Script - ns lookup for DNS Verification test fails

  - by Vazgen

  I'm trying to connect my Hyper-V Server to a Windows 8 client for remote management. I have: Joined server to WORKGROUP Enabled Remote Management Set the server name Set a static IP Set the DNS servers to my ISPs DNS Servers (same as default DNS Servers on my Windows 8 remote management client) Set the correct time zone Created net user on server (net user /add admin password) Added user to special Administrators group on server (hvremote /add:admin) Granted anonymous dcom access on client using hvremote However, the "ns lookup for DNS verification" fails on both the client and server with the same error: Server: my.isps.server.name.net Address: 111.222.333.1 *** my.isps.server.name.net can't find 192.168.1.3: Non-existent domain Thanks for the help.

• Active Directory Support Folder Redirection AND Portable Home Directories?

  - by Robert F

  Does anyone here know if Active Directory will support the use of both Windows Folder Redirection and Mac OS X's Portable Home Directories for synchronizing a user's files to a remote share? I want to synchronize my user's files with a remote share as a way of backing up their data. This is fairly straightforward if a user has only a Windows computer or only a Mac computer. However, will Active Directory support a situation in which a user has both types of computers or they have a Mac on which they're running Windows within Parallels? If I configure a remote share via Group Policies for their Windows files and then configure a different share for their Mac files via ADUC, when they change a file on either computer, will AD know which computer the file was changed on and synchronize that file with the appropriate remote folder? Thanks!

• AWS RDS Timeout

  - by warder57

  I know next to nothing about networking/servers. So I'm assuming I'm missing something obvious. All of the resources I can find on this, either don't work or are outdated. I created a brand new AWS account on the free plan. I created a postgres RDS DB instance. I made sure that this RDS instance is set to publicly accessible. This RDS instance has the default VPC/Security Group settings. In order to connect to this DB from my local machine, I used pgadmin3 and followed the instructions provided on the AWS documentation page. Seen here: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ConnectToPostgreSQLInstance.html I've double checked all of the information required to connect: Host: whatever.whatever.us-west-2.rds.amazonaws.com Port: 5432 Username: USERNAME Password: PASSWORD When I try to connect to the database, my connection fails due to a timeout. (During step 4 in the above guide.) Can anyone point me to whatever I am missing? Thanks in advance

• While Mail Forwarding with exim, how do I rewrite the To header with true destination address

  - by Jom

  I have mail forwarding setup with exim using a domain forwarding file. virtual_aliases_nostar: driver = redirect allow_defer allow_fail data = ${if exists{/etc/valiases/$domain}{${lookup{$local_part@$domain}lsearch{/etc/valiases/$domain}}}} file_transport = address_file group = mail pipe_transport = virtual_address_pipe retry_use_local_part domains = lsearch;/etc/localdomains unseen It is working fine. However, I would like to rewrite the "to" header. In my system filter, I would like to put something like: headers remove to headers add "To: $recipient:" I've tried: headers remove to headers add "To: $recipient:" headers remove to headers add "To: $h_env-to:" headers remove to headers add "To: $env-to:" The intent is to have the end recipient see their own email address in the To: line of their mail client. I can't seem to figure out what the correct header is for the final destination of the email so that I can put it in the to header. I've read through the Exim docs and can't seem to find it. I've also looked in the headers in an email at a mail client and can't see it there either. Any suggestions would be appreciated.

• Is there a way to delay a forced reboot?

  - by jduff

  I realize this is more appropriate for our company's admin group to field. However, pretend they are unresponsive just for the sake of discussion =) If my system is prompting me to reboot now or in a set time (say in 15 mins) is there a way to delay that even further? It is usually just an inconvenient time and I would like to delay beyond the stated time. (ex) System Restart Required: A newly installed program requires this computer to be restarted. Please save your work and restart your computer. Your computer will automatically be restarted in: xxmins... Thanks for any responses in advance!

• Disable the Taskbar in Windows 7

  - by ToastMan

  Hi all, I got Windows Server 2008 and Windows 7. We need to run an application on certain computers with very restricted access to other windows functions. Is there a way to disable the taskbar for client users on W7 computers? I looked in the Group Policies but it's not there. Also, I am aware of Taskbar Eliminator, but it doesn't remove the Start button which is not good for me. Any suggestions are very appreciated. Thank you. Toast

• How can I get vim to set an ACL on its swap files?

  - by thsutton

  I use vim on an OS X Snow Leopard Server machine. A number of the directories I work in have ACLs (so that various groups of users can access them over AFP) that are inherited. For some reason, when I'm working in one of these directories, vim cannot read it's own swap files. It can create them fine but can't read them which, for some reason, makes it display the "swap file already exists" message (and no, the swap file does not already exist). vim -r lists the newly created swap file as "[cannot be read]". The owner and group are correct and the permissions are 0600, and the ACLs on the swap file and the file I'm editing are identical (as disclosed by ls -le and compared with diff). groups returns the same thing whether invoked from my login shell or via :! in vim. Has anyone encountered (and hopefully resolved) a problem like this before?

• Task Scheduler : Logon as Batch Job Rights

  - by Brohan

  I'm trying to set up a scheduled task which will work under the Network Administrators account, whether the account is logged in or not (on a specificed computer) According to the Task Scheduler, I need 'Logon as batch job rights'. Attempting to change this setting in the Local Security Policy window has it the option to add the Administrator account to the groups greyed out. Currently, only LOCAL_SERVICE may Logon as Batch job. Attempting to add administrator to this group hasn't worked. How do I make it able to set this permission so that I can run tasks if I'm logged in or not?

• Owner of uploads directory is `www-data` but this prevents FTP access via PHP scripts

  - by letseatfood

  To allow write access to Apache, I needed to chown www-data:www-data /var/www/mysite/uploads to my site's upload folder. This allows me to delete files from the folder via unlink() in a PHP script. Unfortunately, this prevents another PHP script, which uses FTP functions, from working. I think it is because the FTP user is mike and now that the uploads directory is owned by www-data, mike cannot access it. I added mike to the group www-data, but this does not fix the issue. Can somebody advise me on how to allow PHP FTP functions to work in addition to file deletion using PHP's unlink() function?

• postfix/postdrop Issue with Solaris 10 (sparc) - permissions

  - by Zayne

  I am trying to get postfix (installed from blastwave) working on a Solaris 10 server, but only root is allowed to send mail. The problem appears to be permission related with postdrop. postdrop: warning: mail_queue_enter: create file maildrop/905318.27416: Permission denied I've checked that /var/opt/csw/spool/postfix/maildrop and /var/opt/csw/spool/postfix/public are both in the 'postdrop' group. main.cf contains setgid_group = postdrop. ppriv on postdrop as non-root user reports: postdrop[27336]: missing privilege "file_dac_write" (euid = 103, syscall = 5) needed at ufs_iaccess+0x110 I'm at a loss as to what to do next. I'm don't have much experience with Solaris; I use Linux daily. Any suggestions?

• Mounting Google Driva via WebDav directly on Google

  - by WoJ

  I would like to mount on my RPi my Google Drive using davfs2 but I did not find any direct way to do it for Google Drive. There are instructions on how to use dav-pocket to indirectly do that but these are from 2010. Google group discussions about the lack of direct WebDAV access to Google are roughly from the same time and I could not find any other way to do the mount. Has anything changed and would anyone know if Google enabled WebDAV - and if so what is the URL? An alternate synchronization system would be fine as well (rsync for instance) - I did not find any particular infos either Thank you!

• Does Exchange 2010 lift the restriction that DL addresses must be in Active Directory?

  - by Justin Grant

  We'd like to enable end-users to be able to create and maintain their own email distribution lists in Exchange 2010, where those lists may include users inside the company but also customers, partners, etc. who are outside the company. One of the limitations in Exchange 2007 (see this question) was that any member of a DL had to have an entry in active directory. You couldn't just take a group of email addresses (both inside and outside my company) and create an Exchange DL with those addresses without involving Active Directory admins to create entries for each external user. For a company creating hundreds of small mailing lists every month, this was an unacceptable IT expense. So we had to use a separate mailing list solution (GNU mailman) for DLs which included external users. Is this limitation relaxed in Exchange 2010 so we can throw away GNU mailman and use Exchange instead?

• Router's ssid changes from infrastructure to ad-hoc

  - by waldo

  For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop. Details: - D-Link DSL-2740B router set to WPA2-PSK (Personal) - Enable Wireless : Yes - Wireless Network Name (SSID) : ###### - Country : Australia - Wireless Channel : 1 - 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b - Channel Width : Auto 20/40 MHz - Transmission Rate : Best (automatic) - Hide Wireless Network : No - Group Key Update Interval : 0 (seconds)

• How to configure sudoers to always keep LD_LIBRARY_PATH envrionment variable?

  - by Yanick Girouard

  No matter what I try, it seems that the LD_LIBRARY_PATH environment variable is not kept after I run a command with sudo. The only way I managed to have it stick, is to prefix my sudo command with LD_LIBRARY_PATH=/the/path whenever I call it from the command-line, but I would like to not have to do this every time. It seems the env_keep option ignores this variable, and so does the exempt_group option. My %group currently has ALL=(ALL) NOPASSWD:ALL as its access in sudoers. I would like this specific environment variable to be kept for any command I run. How can I do this? My server is running Red Hat Enterprise Linux 5.7.

• Remote desktop connection issues in windows server 2003

  - by rboorgapally

  Hi all, We are running windows server 2003 at our work place. I have enabled the remote desktop connections. I have also added all the users who connect to the server(three to four people) to the RDC group of users. Many of these users are also having Administrator access. The problem we are facing is that the connection is suddenly lost when we are working on something. Also, at times the system restarts by itself. Is this issue related to the limit on the number of users able to connect to the system? If so, why does the system accept new connections and/or terminate the existing connections? Has this anything to do with the users having administrator access so that all have equal prority and that is why existing connections are stalled? Also, please differentiate between console remote desktop and non console remote desktop.
