  • SSH broken after homedir permissions and hostname change on EC2-hosted Ubuntu

    - by dimadima
    I changed my instance's hostname using the hostname utility and then set it in /etc/hostname so that the new name survives reboot. My main motivation was for differentiating between instances at the prompt using the \h format in PS1. EDIT I also changed permissions on my home directory. I made my home directory group writeable. Now I can no longer SSH into the machine. The short of it is the error Permission denied (publickey). Running ssh -v, the more verbose output is: debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /Users/dmitry/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /Users/dmitry/.ssh/ec2key.pem debug1: read PEM private key done: type RSA debug1: Authentications that can continue: publickey debug1: No more authentication methods to try. Permission denied (publickey). Should I have done something after changing the hostname? Now I can't get into the instance! :(

  • Why aren't Heroku syslog drains logging to rsyslogd?

    - by Benjamin Oakes
    I'm having a problem using syslog drains as described in https://devcenter.heroku.com/articles/logging. To summarize, I have an Ubuntu 10.04 instance on EC2 that is running rsyslogd. I've also set up the security groups as they describe, and added a syslog drain using a command like heroku drains:add syslog://host1.example.com:514. I can send messages from the Heroku console to my rsyslogd instance via nc. I see them appear in the log file, so I know there isn't a firewall/security group issue.  However, Heroku does not seem to be forwarding log messages to the server that heroku drains lists. I would expect to see HTTP requests, Rails messages, etc. Is there something else I can try to figure this out? I'm new to rsyslogd, so I could easily be missing something.

  • syntax error: unknown user 'munin' in statoverride file

    - by John
    Server running Ubuntu 12.04 lts I installed munin the other day on a server. I decided later to remove it with apt-get. I noticed that not everything was removed from the installation so manually removed the munin web directory and also removed the munin user-name and group from the sever. However I have just now tried to run apt-get upgrade which is now returning an error: dpkg: unrecoverable fatal error, aborting: syntax error: unknown user 'munin' in statoverride file E: Sub-process /usr/bin/dpkg returned an error code (2) I am now out of my depth. What does this mean? Google results have not really been helpful. Can anyone help? Thanks, John

  • Can't access certain specific IP/domain on Windows 7

    - by jfrobishow
    Been banging my head on the wall for some time now. I have a fresh install of Windows 7 - Ultimate ~x86. Some IPs can't resolve properly, it doesn't matter if I try using Firefox, Chrome or IE I end up with a domain not found (server not found, etc.) I am behind a router, all the other computers aren't affected only this Win 7 machine. It's only certain sites. e.g. xkcd.com, facebook's cdn, google group. Things I have tried: flushdns ipconfig renew Disable IP v6 on the NIC Double checked that the computer was in the right timezone @ the right time. Reinstall the NIC driver. Again 90% of the sites will work but not the major one :P help!!!

  • Monitoring System for the cloud?

    - by Maxim Veksler
    I need a monitoring system, much like ganglia / nagios that is build for the cloud. I need it to support : Adding / removing nodes dynamically. (Node shuts down, dose not imply node failure...) Dynamic node based categorization, meaning node can identify them self as being part of group X (ganglia gets this almost right, but lacks the dynamic part...) Does not require multicast support (generally not allowed in cloud based setups) Plugins for recent cool stuff such as Hadoop, Cassandra, Mongo would be cool. More features include: External API, web interface and co. I've looked at Ganglia, munin and they both seem be almost there (but not exactly). I would also go for reasonably priced Software as Service solution. I'm currently doing research, so Suggestions are highly appreciated. Thank you, Maxim

  • cannot connect to MS FTP 7.5 on Windows 2008 on Amazon EC2 instance

    - by minerj
    I have just installed the MS FTP 7.5 upgrade on my Windows 2008 Server (Service Pack 2) running on an Amazon EC2 instance. In the FTP Firewall Support settings for the server in IIS Manager I have set up the passive port range 45001 - 45005 and also set the External Firewall IP address to match the assigned Amazon Elastic IP address. Using the AWS Console I changed the Security Group for the server to allow access to the server through ports 21 and 45001 through 45005. Using an FTP client (either the command line FTP client or Windows Explorer) on the Amazon server I can connect to the FTP server but I cannot connect with an external FTP client. When I checked to see which ports were open on the server using Shields Up it shows that port 21 is open but ports 45001 to 45005 are closed. I assume I'm missing something. Any help greatly appreciated.

  • 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?

  • Connect to RDS inside a VPC using Opsworks located in another VPC

    - by Consuelo Merino
    I have a RDS instance (mysql) inside a VPC called vpc-a (10.0.0.0/16). This instance is private, it can only be accessed from vpc-a. We created a stack on opsworks inside another VPC called vpc-b (10.1.0.0). We want to connect opsworks to the RDS but it doesn't work. It refuses to connect. I tried adding said subnet to the RDS security group. Also read a lot of documentation but I haven't stumbled across the answer. Any help would be greatly appreciated.

  • Different background color for multiple filetypes in vim

    - by puk
    Is it possible to have different background colors in vim (ie. one light, one dark) when dealing with files with multiple filetypes (ie. :set ft=html.php)? In PHP code with HTML embedded, it can be difficult to see one single PHP statement amongst dozens of HTML lines, see below. I'll settle for anything, be it different bg color, a marker in the margin, a second left margin (one vim plugin does this for marks), maybe highlighting the <?php tag for example (although that's less than ideal) EDIT: I don't think this is possible at the syntax level as the syntax appears to use a limited number of elements (String, Function, Identifier...). This is no doubt to allow for the easy integration with colorschemes. SyntaxAttr is a good plugin to demonstrate this. Put it over any part of the code and it will tell you what syntax group it belongs to.

  • Ubuntu Wireless card not found

    - by user32121
    Hello all, I'm trying to setup Ubuntu on an old PC. I ran the following command, lspci, in order to get info on the wireless card installed. 00:0a.0 Ethernet controller: Marvell Technology Group Ltd. 88w8335 [Libertas] 802.11b/g Wireless (rev 03) Does anyone know where I can get drivers for this card/chip? And also, how to install (I'm rather new to linux). Also, I'm sure the card is working because I just formatted over xp, and everything was working well. Thanks in advanced!

  • Installing Bugzilla on Ubuntu 9.04 and Plesk

    - by makeflo
    Hey guys. I'm trying to install the latest Bugzilla version on my ubuntu server. (Want to use a subdomain like bugs.domain.com) I already installed all necessary perl modules and check_modules.pl doesn't show any errors. But when I'm running the testserver.pl script I get the following: TEST-OK Webserver is running under group id in $webservergroup TEST-FAILED Fetch of images/padlock.png failed I'm also not able to visit ANY file within the bugzilla folder from the browser. I'm always getting a 404 error. The bugzilla folder and all containing files are set to apache as the owner. I tried to enter the apache configuration form the installation guide in the http.include file of the domain and in the vhosts.conf file of the subdomain as well. I don't know what to do... Playing with plesks' suexecgroup doesn't bring any solution... I hope you can help me! Thanks in advance!

  • "The user account does not have permission to run this task"

    - by Ken
    I'm trying to get a scheduled task to run on Windows Server 2008. It has been working fine for months, and then hung, so I killed it, and now I can't get it to start. (In case it's not obvious, I'm not a Windows sysadmin by any stretch of the imagination. I inherited responsibility for this system, more or less.) The error it gives is: "The user account does not have permission to run this task". The task's "author" is "A". The task's "When running the task, use the following user account:" is "B". And my user is "C". All of A, B, C are members of the Administrators group, so I'm a bit puzzled as to why it thinks I don't have permissions to run this. Ideas?

  • 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.

  • 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!

  • Cannot get Backup Exec to backup Exchange.

    - by Shawn Gradwell
    I have a media server, Windows Server 2008 SP2 running Backup Exec 2010 R2. The SQL and other Windows agents work but I cannot backup the Exchange 2010 server running Windows Server2008 R2. I have the correct license for the Exchange agent - installed on the media server, and I installed Exchange Management tools on the media server. The 'Microsoft Exchange Database Availability Group' option is greyed out and if I select the server under a new backup job I can expand the 'Microsoft Information Store' option and see the mail database name but showing 0Kb. When I try to back it up it gives an error displaying: The job failed with the following error: Backup Exec attempted to back up an Exchange database according to the job settings. The database was not found, however. Update the selection list and run the job again.

  • 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?

  • Using Supervisord, how can I start a brand new worker via supervisorctl without restarting other workers?

    - by cballou
    Let's say I have a number of existing workers running in supervisord. I want to add a new worker to the group as well as start the new worker. I perform the following steps: I modify the file /etc/supervisor/supervisord.conf and add the new worker config Back on the command line, I enter sudo supervisorctl I run reread to read the new configuration file settings. Attempting to run start workers:exampleWorkerName gives the error workers:"exampleWorkerName": ERROR (no such process) So, my question is, how can I start this new worker process without affecting my other existing workers? I'd rather not perform a supervisorctl reload or /etc/init.d/supervisord restart command.

  • Utility to put taskbar on multiple monitors with task grouping?

    - by davr
    Right now I use UltraMon to extend my taskbar across multiple monitors. So windows on the first monitor show up on the taskbar on the first monitor, and windows on the second monitor show up on the taskbar on the second monitor. However, UltraMon does not support "Task Grouping", a feature in Windows since XP. Basically if you have many windows open, it will group together windows from the same app in a single taskbar entry. So if I have 22 explorer windows open, I'll only see a single explorer entry, and if I click it, a menu of the 22 windows shows up. Ultramon doesn't support this, instead I see 22 taskbar entries. Are there any utilities (or built in to windows 7 ways?) that will extend the taskbar across multiple monitors, and support task grouping on the secondary monitors?

  • 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?

  • Personal Virtual Desktop Collection: User Assignment

    - by Fitzroy
    Using Windows Server 2012 Remote Desktop Services, I have a 'Personal Virtual Desktop Collection' with automatic user assignment enabled. According to Microsoft "Personal virtual desktops are permanently assigned to a user account and the user logs on to the same virtual desktop each time." Is there a way either through the Server Manager UI or PowerShell to determine which user has been assigned to which VM? The only way I have found so far is to query the 'Remote Desktop Users' group on each VM in the collection, however that requires each VM to be powered on. There must be a better way.
