  • =?UTF-8?B??= in Emails sent via php mail problem

    - by Camran
    I have a website, and in the "Contact" section I have a form which users may fill in to contact me. The form is a simple form which action is a php page. The php code: $to = "[email protected]"; $name=$_POST['name']; // sender name $email=$_POST['email']; // sender email $tel= $_POST['tel']; // sender tel $subject=$_POST['subject']; // subject CHOSEN FROM DROPLIST, ALL TESTED $text=$_POST['text']; // Message from sender $text.="\n\nTel:".$tel; // Added to message to show me the telephone nr to the sender at bottom of message $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); Could somebody please tell me why this works most of the time, but sometimes I receive email whith no text and the subject line showing =?UTF-8?B??= I use outlook express, and I have read this http://stackoverflow.com/questions/454833/system-net-mail-and-utf-8bxxxxx-headers but it didn't help. The problem is not in Outlook, because when I log in to the actual mailprogram where I fetch the POP3 emails from, the email looks the same. When I right click in Outlook and chose "message source" then there is no "From" information. Ex, a good message should look like this: Subject: =?UTF-8?B?w5Z2cmlndA==?= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: John Doe However, the ones with problem looks like this: Subject: =?UTF-8?B??= MIME-Version: 1.0 Content-type: text/plain; charset=UTF-8 From: As if the information has been lost somewhere. You should know also that I have a VPS, which I manage myself. I use postfix as an emailserver, if thats got anything to do with it. But then again, why does it work sometimes? Also another thing that I have noticed is that sometimes special characters are not shown correctly (by both Outlook and the webmail). For instance, the name "Björkman" in swedish is shown like Björkman, but again, only sometimes. I hope anybody knows something about this problem, because it is very hard to track down for me atleast. If you need more input let me know.

  • Running Ubuntu with multiple monitors having a panel each

    - by Andreas Grech
    I have just installed Ubuntu and I'm trying to set up a correct configuration for having multiple monitors. I want the two monitors to have their own workspaces, yet the ability to drag a window from one monitor to the next. I also want a separate panel (taskbar) for each monitor. I have played around with nvidia-settings and tried the following different configs: Having both monitors `Use separate X screen" A panel for each monitor but I couldn't drag windows from one monitor to the next Using TwinView The ability to drag windows from one monitor to the next but only a single panel for the primary display Now I want to have the above configurations combined. Basically, as I stated beforehand, having a separate panel for each monitor and also the ability to drag windows across monitors. Can anyone provide me with suggestions please?

  • Apache - The name

    - by Josh
    I am working on a migration to a newer virtualized server. The old one has Apache 2.2.4 according to the old servers phpinfo(). The new one with the most up to date has 2.2.3 . How can this be assuming no trickery is involved? The old one is years old. Alot of the guides I reference use apache2 in folders names and many of the conventions. The newest version of things, as I understand it is called httpd. Did apache change the name from what it originally was? (i.e. break the web server component into its own project called httpd, I realize the original daemon was probably still called httpd)

  • Debian: video problems with VLC

    - by kemp
    I have a problem playing AVI divx files with VLC. Yesterday upon start VLC showed an error message complaining about divx codecs and refused to proceed. Today the player starts but the video is squashed horizontally (it occupies roughly 1/4th of the VLC window which is for the other part black). I'm on an updated testing system, and before yesterday VLC was playing fine. In the meantime - after a recent dist-upgrade - I cannot run X with proprietary ATI drivers anymore, I have to use the FOSS radeonhd ones instead. I don't know if that's related but I thought it could be worth mentioning (and by the way if anyone has suggestions about this problem too, that'd be very much appreciated). How can I fix VLC's problem?

  • *nix: Run as different user GUI

    - by singpolyma
    I want to run an application using only GUI as a different user. Not root. I want the user to be presented with a dropdown of system users, select one, enter the password, and the app gets run as that user. Like gksudo but user to run as specified in GUI and not as switch. Does such an app exist?

  • Removing DS_Store files and variants?

    - by Ron Gejman
    I am running an Ubuntu 10.04.1 LTS server. Frequently I open up files using AFP from my Mac. Inevitably this created .DS_Store files on the server (although for some reason they are named :2eDS_Store. However, it also creates variants on DS_Store files. These variants are often named similarly to other files in that directory. E.g.: ~$ ls total 60K -rw-r--r-- 1 tarakhovsky 16K 2010-11-30 18:28 :2eDS_Store drwx--S--- 4 tarakhovsky 4.0K 2010-11-08 13:58 :2eTemporaryItems/ lrwxrwxrwx 1 tarakhovsky 15 2010-10-19 17:44 bigdisk -> /media/bigdisk// ... drwxr-xr-x 3 tarakhovsky 4.0K 2010-11-03 18:24 Temporary Items/ drwxr-xr-x 3 tarakhovsky 4.0K 2010-11-30 01:34 tmp/ ... I've disabled creation of DS_Store files using: defaults write com.apple.desktopservices DSDontWriteNetworkStores true so hopefully this won't continue to occur—but I really want to get rid of all of the existing variants of DS_Store files already on the server. Any ideas as to why these variants are being created and how I can get rid of them all?

  • How do you apply development practices like version control, testing and continuous integration/deployment to system administration?

    - by arex1337
    Imagine you're going to manage a number of servers with a number of different services that's used by a number of people. Now say you want to reconfigure or replace some software on one of those servers. Obviously you don't want to work on servers that are in production. If this was a code change, as a developer, I would make the change on my local development machine, test it locally and commit the change to a version control system. The changes could then be deployed in a staging environment, tested further and finally deployed in a production environment. It would also be easy for me to roll back, if necessary. Generally, or specifically, how do you achieve this in system administration? (The first thing that comes to mind is to use virtual machines and put virtual machine images in version control, but I'm sure there is a lot of literature and clever solutions I'm not presently aware of.)

  • Trying to limit IMAP folders/mailboxes my iPhone/iPad sees

    - by QuantumMechanic
    (Note: I am using dovecot 1.0.10 on Ubuntu 8.04.4 LTS. Yes, I know I need to upgrade before next year :) (Note: The SMTP/IMAP server in question only serves my family, so there's only a very few users. Certainly what I propose below, even it it works, would be a logistical nightmare with any significant number of users). I have noticed (and have confirmed via google) that the iOS mail app is terrible in its handling of IMAP subscriptions, namespaces, etc. For example, my iPhone and iPad will see EVERYTHING (all mailboxes, folders, etc.), whereas clients like Thunderbird, alpine, etc. only see what I tell them to see. This makes it an incredible pain to move mail between mailboxes because I have to scroll through a gazillion things. The mail_location in dovecot.conf is: mail_location = mbox:%h/Mail/:INBOX=/var/mail/%u To get around this, I've been considering doing the following for user foo: Create a dovecot userdb with a foo-ios virtual user in it, whose UID is identical to that of the real (in /etc/passwd) foo user and with a homedir of /home/foo-ios. ln -s /var/mail/foo /var/mail/foo-ios mkdir -p /home/foo-ios/Mail cd /home/foo-ios/Mail ln -s /home/foo/Mail/mailbox-i-want-visible mailbox-i-want-visible Make symlinks for the rest of limited set of mailboxes/folders I want visible to the iOS mail app. chown -R foo:foo /home/foo-ios Change iOS mail app settings to log in as user foo-ios instead of user foo. Will this work or will there be some index/file corruption hell because there will be two sets of indexes (one set living in /home/foo/Mail/.imap and other set living in /home/foo-ios/Mail/.imap) indexing the same underlying mbox files? And I'd be more than happy to hear of a better way to do this with dovecot! (Or to hear that dovecot 2.x works better with iOS devices).

  • Recommended way to restrict Apache users

    - by Dor
    Following on why should we restrict Apache users, another two questions arises: What is the recommended method of restricting the places Apache users can traverse & read in the file system? What to do against fork bombs and other shell scripting problems? (bash scripting is allowed) My possible solutions (I prefer to know which solution you choose and why): chroot OR mod_chroot disable bash OR use Restricted BASH Please offer another solutions if you find appropriate. (perhaps selinux is?) Current status: Users are allowed to executed bash scripts (via PHP for example) suexec is active Apache requested are served with FastCGI for PHP

  • syslog ip ranges to specific files using `rsyslog`

    - by Mike Pennington
    I have many Cisco / JunOS routers and switches that send logs to my Debian server, which uses rsyslogd. How can I configure rsyslogd to send these router / switch logs to a specific file, based on their source IP address? I do not want to pollute general system logs with these entries. For instance: all routers in Chicago (source ip block: 172.17.25.0/24) to only log to /var/log/net/chicago. all routers in Dallas (source ip block 172.17.27.0/24) to only log to /var/log/net/dallas. Finally, these logs should be rotated daily for up to 30 days and compressed. NOTE: I am answering my own question

  • Solr startup script problem

    - by Camran
    I have installed solr and it works finally... I have now problems setting it up to start automatically with a start command. I have followed a tutorial and created a file called solr in the /etc/init.d/solr dir...

Also here is where I have solr installed: var/www/solr and here is the start.jar file located: var/www/start.jar Help me out if you know whats causing this. Thanks BTW: OS is ubuntu 9.10

  • Middle mouse click in VirtualBox (Vista host, Debian guest)

    - by Ken
    I'm running Virtualbox on Windows Vista. I have a Microsoft USB mouse (it says "Comfort Optical Mouse 3000") with left and right buttons, and a mousewheel in the middle. If I press down on the wheel, it pretty obviously makes a "click". I'm running Debian inside Virtualbox, and it's working great, but middle-mouse-click does nothing. Left and right click, and scrolling with the wheel, work fine. Is there any way to get middle-mouse-click to work in my virtual machine?

  • Getting Pango-WARNING: Invalid UTF-8 string passed to pango_layout_set_text()

    - by geerlingguy
    About three days ago, I noticed the exim mailqueue started filling up on one of my servers, and upon inspecting some of the emails using # exim -Mvb $ID, I noticed they were being sent to some system email address (which is not a real address), and the body of the messages were as follows: (process:8259): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text() I'm wondering what could be causing this strange issue, as I've never heard of 'pango' at all... I've never seen that function used in my lifetime! It seems the process id (PID) is for an apache process, though, as the pids are always gone by the time I use # ps -aux to look them up. Edit: Whoops! Forgot to include the subject - looks like it's actually munin-cron that's bringing up the issue: Subject: Cron /usr/bin/munin-cron --force-root

  • Fedora 15: em1 recently dissapeared and hostapd no longer serves internet to wirelessly connected devices

    - by Daniel K
    I have a laptop running hostapd, phpd, and mysql. This laptop uses an Ethernet connection to connect to the internet and acts as a wireless access point for my workplace's wifi devices. After installing some software and reconnecting my Ethernet elsewhere, my "em1" device is no longer present and wirelessly connected devices can no longer reach the internet. The software I recently installed is: pptp, pptpd, and updated some fedora libraries. I have also recently moved my desk and laptop to another location and thus had to reconnect the Ethernet elsewhere. Wifi devices no longer have access to the internet. Wirelessly connected devices are able to successfully log into the laptop, showing full strength, correct SSID, and uses the proper password. However, when I tried to connect to a site like google, the request times out. The device "em1" also no longer appears on my machine. Running: # ifup em1 will give me the following output: ERROR : [/etc/sysconfig/network-scripts/ifup-eth] Device em1 does not seem to be present, delaying initialization. And running: # dhclient em1 has the following output: Cannot find device "em1" When I run # dmesg|grep renamed, I get the following: renamed network interface eth0 to p4p1. I've tried to connect to the internet through p4p1 directly from the laptop and was successful. However, my wireless devices connected to my laptop are not able to connect to the internet. I have uninstalled pptp and pptpd using # yum erase ... but the problem still persists. To install pptp I used: # yum install pptp To install pptpd I did the following: # rpm -Uvh http://poptop.sourceforge.net/yum/stable/fc15/pptp-release-current.noarch.rpm # yum install pptpd To update my fedora libraries I used: # yum check-update # yum update EDIT: Running # route produces the following results: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.11.200.1 0.0.0.0 UG 0 0 0 p4p1 10.11.200.0 * 255.255.252.0 U 0 0 0 p4p1 172.16.100.0 * 255.255.255.0 U 0 0 0 wlan0

  • Why won't apache load a symlinked file from conf.d?

    - by kdt
    I have an apache configuration file which works fine when it's placed directly in /etc/httpd/conf.d/foo.conf. However, when I move the same file somewhere else (for example, move it to /tmp/foo.conf) and then create a symlink with ln -s /tmp/foo.conf /etc/httpd/conf.d then apache fails on startup with: httpd: could not open document config file /etc/httpd/conf.d/foo.conf I've tried making the file and the symlink mode 777, and tried changing them to be owned by the apache user. It seems like apache is failing to load the file purely on the basis of it being a symlink, but I'm sure I've used symlinks successfully on other machines. Is there something I'm missing? Does apache have an option for refusing to load config files if they're symlinks? The operating system is CentOS 4.4, apache version 2.0.52.

  • NFS confusion - writing many small files

    - by Antonis Christofides
    I have a Debian squeeze amd64 which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 176.9.116.102:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS directory goes at more than 100 MB/s.) I am confused by the description of async in NFS. If my application accesses the local directory, system calls like write and close return even if caches have not been flushed to permanent storage. Apparently this is not true with NFS sync behaviour. However, with NFS async behaviour, even calls like fsync are ignored. Isn't it possible to work like local files, i.e. generally work asynchronously, but honour fsync and O_SYNC?

  • stunnel: SSL-to-SSL? (for smtp/imap)

    - by nonot1
    Hello, How can I configure stunnel to accpet SSL connections, and connect then to an SSL port on a different server? Here is my setup: Our ISP's server, "Mail Server", supports smtp/imap over SSL. (Not starttls. Just over ssl.) But, I have a bunch of client machines that will only trust a specific, internal, root certificate. Thus, they can not connect to "Mail Server". For these client machines, I'd like to make a dedicated "Mail Tunnel" host that uses stunnel to listen with an in-house signed SSL certificate, and just forward data to "Mail Server" using a 2nd SSL connection. Can this be done? What would be the specific steps for Ubuntu Server 10.10? (I'm not too familiar with persistent service configuration.) Thank you

I found gnome-shell today, that seemed awesome. There are other ones, less well known, For eg, Abiword is far better than Open Office Org Word processor in many ways. (Altho' I dont like word processors themselves.) What are the other less well known applications that you use and like. One application per answer.
