  • X11 for apache user

    - by fuenfundachtzig
    We are using inkscape to convert SVG images uploaded to our server via a web form. For this inkscape offers a batch mode via the -z option, but this batch mode has a flaw: When inkscape is run by the apache user, it breaks saying $ inkscape -z -W drawing.svg X11 connection rejected because of wrong authentication. The application 'inkscape' lost its connection to the display localhost:11.0; most likely the X server was shut down or you killed/destroyed the application. If you do the same as a normal user you also get errors: Xlib: connection to "localhost:11.0" refused by server Xlib: PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match (inkscape:24050): Gdk-CRITICAL **: gdk_display_list_devices: assertion `GDK_IS_DISPLAY (display)' failed 301.27942 But at least inkscape gives the correct answer (here the number stating the width of the image). Does somebody know how to make this also work for the apache user? Does it make sense to authorize apache to use X (if so how)? In any case it doesn't feel like the right solution...

  • OpenSSH SFTP: chrooted user with access to other chrooted users' files

    - by HannesFostie
    Decided to re-phrase the question entirely in order to not have to make a new one. I currently have an SFTP server set up using OpenSSH's SFTP functionality. All my users are chrooted, and everything works. What I need most right now is for one user, which is not root (because this user can't have any real SSH powers!), to have access to all other users' chrooted dirs. This user's job is to fetch all uploaded documents every once in a while. Directory structure as of now is: /home |_ /home/user1 |_ /home/user2 |_ /home/user3 With ChrootDirectory set as /home/%u User "adminuser" should have access to user1, user2 and user3's directories without having access to /home or at the very least not to anything but /home. Bonus points for the one who can tell me how to let users write inside /home/%u without having to make a new directory inside that dir which they own themselves, and not root as is the case with /home/%u (openssh chroot prerequisite).

  • Exchange ActiveSync does not work for one user

    - by jshin47
    One particular user in our system is unable to connect to Exchange ActiveSync via her iPhone. When I try to connect using my own credentials on her iPhone it works (everything begins syncing), but when I input her credentials, the Settings app verifies the credentials are correct but nothing syncs. For example, if I open Mail, no items are shown. When I attempt to force a sync, it says "Cannot connect to server." In Exchange 2010 Management Console the user is no different than the others. Exchange ActiveSync is set as "Enable" in Mailbox Features. EDIT: Alternatively, if there is some easy way to create a new useraccount/mailbox and copy all of the contents of the old one over, I bet it would work, and that would be fine as well. She is a Mac user so we do not have to worry about her Active Directory account.

  • How to use UMLFS?

    - by Vi
    I'm trying to mount what is inside UML session as FUSE filesystem on host. There's "uml_mount" program which looks like a thing for this purpose, but it fails. What is UMLFS (I haven't found any documentation at all) and how to mount it? uml_mount mounts FUSE filesystem and starts uml_mconsole <umid> umlfs <file descriptor> which tries to send this file descriptor to UML kernel (to deal with further FUSE things), but sending fails. Also I haven't found any signs of FUSE inside a kernel. Do I need some special patch for this?

  • Undeliverable messages to newly migrated Exchange user

    - by johnnyb10
    We are in the process of migrating from our old domain to a new one, part of which involves migrating mailboxes from Exchange 2003 to Exchange 2007. A bunch of users have been migrated already without problems. However, one of the users is having trouble receiving emails from others. When someone sends to him, they get an Undeliverable NDR that says "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients." The message shows the user's distinguished name as /OU=OurDomain/CN=Recipients/CN=USER57137172. The user's account name should just be "USER", so I don't know where the extra numbers ("57137172") are coming from. Thanks in advance.

  • Unable to logoff, disconnect, or reset terminal server user in production environment

    - by l0c0b0x
    I'm looking for some ideas on how to disconnect, logoff, or reset a user's session in a 2008 Terminal Server (unable to login as the user either as it is completely locked-up). This is a production environment, so rebooting the server or doing something system-wide is out of the question for now. Any Powershell tricks to help us with this? We've tried to disconnect, log the user off and reset the session as well as killing the session's processes too, directly from the same terminal server (from the task manager, Terminal Services Manager and the Resource Monitor) with no results. Help! UPDATE: We ended up rebooting the server as no other attempts that we could think of worked. I'll leave this question open hoping someone might have more information about this one issue, and it's potential fixes

  • Simulating mouse clicks at specific screen coordinates

    - by Matteo Riva
    I would like to be able to bind some keys to mouse clicks done in specific locations. For example: when I press F1 I should get a left mouse click at coordinates 300x350, F2 at 600x350 and so on. Even better if this could be bound to a specific window application so that coordinates could be relative to it instead of the base desktop. Is there a software which allows this? ADDITION: Ok autohotkey is great but I have problems with my particular setup. Quoting my comment below: I'm using it with an old game (championship manager 01/02) which runs in windowed mode (and I have to set win98 compatibility for it to run): I can get the mouse to move but no click goes to the application I have read this FAQ but it didn't help, this is the script I tried: SendMode Play SetKeyDelay, 0, 50, Play F1::Click 42, 191 F2::ControlSend ahk_class main, Click, Championship Manager 01/02 Still no luck: pointer moves but no click goes through.

    - by Zaar Hai
    Good day everyone! I have only Ubuntu/Debian machines in my office. I've registered for Windows Azure platform and try to enter their management portal (https://windows.azure.com/default.aspx), but it requires Microsoft Silverlight. I've tried installing latest Moonlight plugin availabing for Ubuntu 11.04, but without any success - after login I see blank page and nothing more (tried both firefox 7.0.1 and chromium-14). Does anyone know how to enter Microsoft Azure management portal from Ubuntu 11.04 or any other linux? Thank you, Zaar

  • Cannot authenticate a domain user with SQL Server 2008

    - by Sambo
    I'm new to setting up Domains so I might be missing something simple here... I've installed SQL Server 2008 on a Windows Server 2008 R2 box and I have another WS2008 R2 box acting as the domain controller. I've joined the SQL server to the domain and it seems to be behaving itself fine. I can ping the DC by name and IP address. I created a domain user 'SPSQLAdmin' that I want to use for database access with SharePoint but I can't seem to log on to SQL with this user. SQL complains, saying that the user belongs to an untrusted domain. I've configured the DC to delegate control for any service to the SQL Server but it doesn't improve the situation. What should I try next? Thanks in advance.

  • How to fix the IE8 favorites menu?

    - by Lance Roberts
    I'm using Windows XP and Internet Explorer 8, and occasionally one off my favorites (Link) folders will get a very small box in the upper right corner (on the favorites menu drop down itself) and not open at all. I can't figure out how it got there or how to disable it, and I have to completely shut IE down and restart it to get rid of it. Any clues on what's going on?

  • Best practices to avoid Jenkins error: sudo: no tty present and no askpass program specified

    - by s g
    When running any sudo command from Jenkins I get the following error: sudo: no tty present and no askpass program specified I understand that I can solve this by adding a NOPASSWD entry to my /etc/sudoers file which will allow user jenkins to run commands without needing a password. I can add an entry like this: %jenkins ALL=(ALL)NOPASSWD:/home/vts_share/test/sudotest.sh ...but this leads to the following issue: how to avoid specifying full path in sudoers file? I can add an entry like this: %jenkins ALL=NOPASSWD: ALL ...but this allows user jenkins to avoid the password prompt for all commands, which seems a bit unsafe. I'm just curious what my options are here, and if there are any best practices I should consider.

  • libvirt's dnsmasq does not respond to dns queries or provide dhcp

    - by Jeremy
    This is on Ubuntu 10.04 server, using KVM to run Ubuntu guests. This system has been working for a long time and I have not changed anything (other than applying security updates), but today I found dnsmasq no longer responds to requests. I cannot say how long this has been broken for me because I don't frequently use the NAT'd guests. So it could have started just after the last updates or some other event and I just now found it. I can connect to port 53 with telnet at 192.168.122.1. I've flushed ip-tables to be sure it wasn't firewall rules and that is not the problem. dnsmasq is running, virsh reports default network as stared. I can't find ANY information on troubleshooting libvirt dnsmasq except that it won't play well with other instances of dnsmasq, which is not the problem. I cannot even find where log entries might be for this service. Any ideas on where to look for more information? edit to add: I added another network and that one works fine. I guess I have a workaround but would still like to figure out how to troubleshoot this problem.

  • Virtualbox port forwarding with iptables

    - by jverdeyen
    I'm using a virtualmachine (virtualbox) as mailserver. The host is an Ubuntu 12.04 and the guest is an Ubuntu 10.04 system. At first I forwarded port 25 to 2550 on the host and added a port forward rule in VirtualBox from 2550 to 25 on the guest. This works for all ports needed for the mailserver. The guest has a host only connection and a NAT (with the port-forwarding). My mailserver was receiving and sending mail properly. But all connections are comming from the virtualbox internal ip, so every host connection is allowed, and that's not what I want. So.. I'm trying to skip the VirtualBox forwarding part and just forward port 25 to my host only ip of the guest system. I used these rules: iptables -F iptables -P INPUT ACCEPT iptables -P OUTPUT ACCEPT iptables -P FORWARD ACCEPT iptables -t nat -P PREROUTING ACCEPT iptables -t nat -P POSTROUTING ACCEPT iptables -A INPUT --protocol tcp --dport 25 -j ACCEPT iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -s 192.168.99.0/24 -i vboxnet0 -j ACCEPT echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A PREROUTING -p tcp -i eth0 -d xxx.host.ip.xxx --dport 25 -j DNAT --to 192.168.99.105:25 iptables -A FORWARD -s 192.168.99.0/24 -i vboxnet0 -p tcp --dport 25 -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.99.0 -o eth0 -j MASQUERADE iptables -L -n But after these changes I still can't connect with a simple telnet. (Which was possible with my first solution). The guest machine doesn't have any firewall. I only have one network interface on the host (eth0) and a host interface (vboxnet0). Any suggestions? Or should I go back to my old solution (which I don't really like). Edit: bridge mode isn't an option, I have only on IP available for the moment. Thanks!

  • Windows XP: Consequences of setting a password for an account

    - by sleske
    I do not quite understand how Windows (specifically Windows XP) handles accounts with/without passwords. As far as I can see, on a fresh Windows XP install I have one default account which has admin rights does not have a password will auto-login (without password prompt) when the computer boots What happens if I set a password for this account? Will it still auto-login? Or will it always prompt for the PW? And generally, what consequences does it have if I set a password? I noted that Scheduled Tasks apparently cannot run under an account w/o password (creating a scheduled task will prompt for the account PW). Is there anything that will not work with a password set? Why is it even possible to have accounts without a password? I have some Unix/Linux background, but the concepts appear a little different under Windows.

  • Windows7 corrupted profile - prevention exists?

    - by Radek
    I have dedicated Windows7 (not on domain) virtual machine for overnight automation testing. Some commands (mySQLdump, tscon.exe) must be run under administrator account. Last week administrator account's profile was corrupted. I fixed it by renaming it in the registry and logging in as administrator. And today it is corrupted again. I use administrator account only to run above commands via runas. Also the computer is restarted via cmd - shutdown command - quite often. Especially every night before automation testing starts. I checked the comp for viruses - did full scan using avast although I believed that the comp is clean. Any idea how to prevent the profile to get corrupted again? update So the first log entry in event log is today from 1.15am and one of my scripts ran runas command as administrator exactly at 1.15am. It was second time that runas war executed though after the testing started. The same happened second day in a row. Before the testing starts I need to copy one file that is locked. So I run handle.exe from runas to unlock it. That is what I think causing the profile to get corrupted. I am not able to reproduce it by myself. The message from event viewer is Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. DETAIL – The process cannot access the file because it is being used by another process.

  • Blocking apache access via user agent string

    - by Tchalvak
    I've got a scripter who is using a proxy to attack a website I'm serving. I've noticed that they tend to access the site via software with a certain common user agent string (i.e. http://www.itsecteam.com/en/projects/project1_page2.htm "Havij advanced sql injection software" with a user_agent string of Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727) Havij). I'm aware that any cracking software worth it's salt will probably be able to modify it's user agent string, but I'm fine with the scripter having to deal with that feature at some point. So, is there any software out there for automatically blocking access & permanently blacklisting by matching user agent strings?

  • Postfix/dovecot remove LDAP user

    - by dove221
    I have to remove or blacklist an LDAP/dovecot user. The authentication is setup from active directory what I cannot manage so I thought there should be a way at least to disable this specific user on the mailserver locally. # Virtual Accoutns - LDAP - MS AD virtual_mailbox_maps = ldap:/etc/postfix/ldap_mailbox_maps.cf virtual_alias_maps = ldap:/etc/postfix/ldap_alias_maps_redirect_true.cf ldap:/etc/postfix/ldap_alias_maps_redirect_false.cf ldap:/etc/postfix/ldap_mailbox _groups.cf virtual_mailbox_domains = domain.com virtual_uid_maps = static:1000 virtual_gid_maps = static:1000 virtual_transport = dovecot dovecot_destination_recipient_limit = 1 Anybody knows how to do it? I followed this guide for disabling 1 user through postfixes access file: http://www.cyberciti.biz/faq/howto-blacklist-reject-sender-email-address/ Unfortunately it doesn't work. It's like the settings stored in LDAP are overruling the access rule. Instead of postfix rejecting the mail it keeps accepting it. Thanks!

  • Switching over an email address from a distribution group to a user account in Exchange 2003

    - by Sevdarkseed
    I'm currently in a transition mode. We currently have a Distribution Group called Quotes and Orders that send out emails to several users. I'm told that a better method would be to create a user and then give access to that fictitious user's email account so that everyone would be able to see everything that goes out and is responded to in a single account. However, I'm not sure what the best method would be for creating an account and shutting down the distribution group. I'm thinking more along the lines of the steps that considered best practice to remove the email account from the distribution group and attach it to the user account. Any thoughts?
