  • GDM login screen is not displayed with VNC

    - by niboshi
    Hi, I set up VNC server with xinetd. Also configured GDM so that XDMCP is enabled. VNC connection seems okay, but GDM login screen is not shown. Instead I can only see old bare X screen (gray meshed background and X-shaped mouse pointer), which I can't do any interaction with it. What can I do to fix the problem? No log is written below /var/log/. Server distribution: Ubuntu marverick /etc/xinetd.d/vnc is like below: service vnc1024 { disable = no socket_type = stream protocol = tcp wait = no user = nobody server = /usr/bin/Xvnc server_args = -inetd -query localhost -geometry 1024x768 -depth 24 -once securitytypes=none port = 12345 } /etc/gdm/custom.conf: [daemon] [security] DisallowTCP=false [xdmcp] Enable=true [gui] [greeter] [chooser] [debug] [servers] /etc/services is also configured. Thanks

  • SSH Tunnel for Remote Desktop via Intermediary Server

    - by Mihai Todor
    I've seen many examples of SSH tunnels on the nets, but I'm still having no luck with this. Here's the setup: Windows 7 PC in a private network, sitting behind a firewall, with PowerShellInsider SSH server set up and working fine. Public access Linux server, which has access to the PC. Windows 7 laptop, at home, from which I wish to do remote desktop on the PC. Now, here's what I've tried so far: SSH tunnel from my laptop to the Linux server: ssh -f my_user@LINUX_SERVER -L 6666:LINUX_SERVER_IP:6666 -N SSH to the Linux server where I've set up a tunnel to the PC: ssh -f 'PRIVATE_DOMAIN\my_user'@PC_NAME -L 6666:PC_IP:3389 -N Unfortunately, I must be doing something wrong, because it doesn't seem to work. Any ideas why or, at least, any suggestions on how can I try to debug this setup? At the moment, I have access to all 3 machines (non-root on Linux), so I can test whatever I want...

  • How do I recover tab cycling in Terminal.app?

    - by Grzegorz Adam Hankiewicz
    Today I've noticed that Cmd+} has stopped working for me in Snow Leopard's Terminal.app as a shortcut to cycle to the next tab. Cmd+{ still works. I've gone to the Preferences-keyboard shortcuts and when I try to create a new shortcut pressing Cmd+} I get Cmd+alt+Ç in the window. I get Cmd+alt+´ when pressing Cmd+{ (I'm on a Spanish macbook pro). I've also noticed that I cannot create a custom shortcut for Terminal.app, because it is not in the list of applications I can create shortcuts for, and neither can I add it to the list. How can I debug what is "eating" the cycle right tab shortcut key? I've got sizzling keys plugin, keyboard remapper (for the esc/capslock key) but I've tried disabling them and still didn't recover the terminal shortcut.

  • eAccelerator ignore my new setting?

    - by Mwebe Nkrumah
    Hi, Im using eAccelerator 0.9.5.2, CentOS 5.3, lighttpd 1.4.22 But because eAccelerator is cached in RAM, I needs too much RAM. So Im trying to cache in hard disk. (my website is not generate money, so Im thinking about cheaper solution) So, I modify /etc/php.d/eaccelerator.ini with below codes: extension="eaccelerator.so" eaccelerator.shm_size="12" eaccelerator.cache_dir="/var/cache/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="0" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="20M" eaccelerator.shm_ttl="1800" eaccelerator.shm_prune_period="0" eaccelerator.shm_only="0" eaccelerator.compress="0" eaccelerator.compress_level="9" eaccelerator.keys="disk_only" eaccelerator.sessions="disk_only" eaccelerator.content="disk_only" So, the output of phpinfo() as below: http://img175.imageshack.us/img175/1104/screenshggot.png But after using "disk_only" in eAccelerator and restart lighttpd & php-cgi using killall, my RAM usage is still high for php-cgi. Reboot the server also not works. The data is created in cache directory, but RAM usage is still high.

  • Gmail for Googleapps mail delivery issues

    - by epeleg
    I have a google apps domain running gmail. One of the owners of one of the email accounts is complaining that some emails don't get delivered to him. I sent him an email that did not get to its destination on one hand but I got no NDR on the other hand. I have already checked that the email was not on in his spam folder. The only thing that he has there is a forwarding rule that is also set up to leave the original in place. I am looking for any tools or ideas on how to debug this.

  • How to repair unbootable Fedora install

    - by Cerin
    How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

  • Testing php mail() in localhost problem

    - by Samir Ghobril
    Hey guys, recently I just installed msmtp in linux and I even send a mail from the terminal and it worked: echo -e "Subject: Test Mail\r\n\r\nThis is a test mail" |msmtp --debug --from=default -t [email protected] But in php, after editing the php.ini file to have this: sendmail_path = '/usr/bin/msmtp -t' and using this piece of code: <?php if ( mail ( '[email protected]', 'Test mail from localhost', 'Working Fine.' ) ){ echo 'Mail sent'; } else{ echo 'Error. Please check error log.'; } ?> I get the Mail sent message but don't receive a message in my inbox. Not even in the spam folder. Anything wrong I'm doing? msmtp configuration file: defaults tls on tls_starttls on tls_trust_file /etc/ssl/certs/ca-certificates.crt account default host smtp.gmail.com port 587 auth on user [email protected] password password from [email protected] logfile /var/log/msmtp.log

  • How to run sshfs through ssh command?

    - by Koryonik
    I tried to run sshfs through ssh in one command. For example, if I do : $ ssh user@host user@host$ sshfs host:/src /target Everything is ok. Now, if I tried this in one command : ssh -t "sshfs host:/src /target" But not mounted point. By using sshfs debug option, it seems volume is mounted and immediately unmounted when ssh connection ended. I also tried to run sshfs in a login shell, but result is the same when exiting shell : ssh -t "/bin/sh -l -c sshfs host:/src /target && /bin/sh" What's wrong ? Is there one another best way?

  • CentOS/Apache killing connections

    - by fin1te
    Getting a really strange error. Basically, whenever I browse to my server (http://[ip_address] or http://[hostname]), it doesn't load, and my active SSH connection drops out. I installed CentOS 5.5, and then httpd and PHP 5.3. No other applications where installed, so I can't imagine it's something else causing it. I also reinstalled CentOS 5.5 again, completely fresh, the only thing I did to it was yum install httpd, and it still caused this issue. I've changed nothing in the config or anything else. Driving me mad, has anyone heard of this? It's really frustrating since everytime I attempt to debug this issue, I get kicked off SSH and have to log back in. Theres nothing in the Apache error logs, and nothing in the access log recording my attempt. Also, the result from uname - Linux [hostname] 2.6.35.4-rscloud #8 SMP Mon Sep 20 15:54:33 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux Thank you

  • Can't get PDO MySQL driver to work on PHP

    Trying to install Vanilla 2 locally using MAMP i got the error: "You must have the MySQL driver for PDO enabled in order for Vanilla to connect to your database". When I check phpinfo() I see: --with-pdo-mysql=shared,/Applications/MAMP/Library --with-pdo-pgsql=shared,/Applications/MAMP/Library/pg When I go and check out those paths I find the files: libpq.5.dylib libpq.dylib libpq.5.2.dylib When I check my php.ini file I see: ; Extensions extension=pdo_mysql.so In php.ini the path to the extension dir is correct (checked it manually): extension_dir = "/Applications/MAMP/bin/php5.3/lib/php/extensions/no-debug-non-zts-20090626/" In this folder I find the file: pdo_mysql.so phpinfo() gives me two sections: PDO PDO drivers: sqlite, sqlite2 and pdo_sqlite SQLite Library: 3.6.22 So everything seems to be fine, but can't get the PDO MySQL driver working :(

  • Unable to log iptables

    - by ActuatedCrayon
    I'm having trouble getting iptables to log to any file. My iptables looks like: Chain INPUT (policy ACCEPT 1366 packets, 433582 bytes) pkts bytes target prot opt in out source destination 869 60656 LOG icmp -- venet0 * 0.0.0.0/0 0.0.0.0/0 LOG flags 0 level 7 Syslogd is the only log helper running. The default syslog.conf didn't work, so I tried adding "kern.=debug -/var/log/iptables.log". But the file already has "kern.* -/var/log/kern.log". There are recent syslog entries, so it's not a permissions thing. I'm running Ubuntu 12.04.1 with 2.6.32-042stab061.2

  • Utilize two gateways on the same network same interface with load balancing

    - by RushPL
    My setup is two ISPs on a single interface and single network. I can either set my default gateway to 192.168.0.1 or 192.168.1.250 and either work. My desire is to utilize both of them with some load balancing. I have tried to follow the advice given in here http://serverfault.com/a/96586 #!/bin/sh ip route show table main | grep -Ev '^default' \ | while read ROUTE ; do ip route add table ISP1 $ROUTE done ip route add default via 192.168.1.250 table ISP1 ip route add default via 192.168.0.1 table ISP2 iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j ACCEPT iptables -t mangle -A PREROUTING -j MARK --set-mark 10 iptables -t mangle -A PREROUTING -m statistic --mode random --probability 0.5 -j MARK --set-mark 20 iptables -t mangle -A PREROUTING -j CONNMARK --save-mark Now then I do "traceroute somehost" repeatedly I can only get route through my default route which is 192.168.1.250. Shouldn't the packets change routes in a random manner? How to debug it?

  • Emacs doesn't load gui.

    - by D Connors
    Hi, whenever I run emacs or emacs23 on terminal I just get the following output: ** (emacs:2620): CRITICAL **: menu_proxy_module_load: assertion `dbusproxy != NULL' failed And the gui doesn't load, and emacs' window never opens. The emacs process doesn't actually crash (the terminal stays busy, and I can see the emacs23 process running with ps -e). I've tried running it with the -D --debug-init arguments, but the same thing happens and the output is exactly the same. However, if I run emacs -nw it successfully runs emacs in terminal mode as if nothing were wrong. Strangely, this problem only started happening the second time I ran emacs today. The first time it worked perfectly fine. Since then, I've tried rebooting and I've tried purging the emacs installation, to no success. I haven't installed any new packages today, but I might have upgraded some, could that be the reason? Is there a way to find out which packages were installed/upgraded today? Thanks I'm running Ubuntu Lucid

  • Domain Computers Not Listed In Network

    - by Giawa
    Our network computers are all connected to a domain, and I can see them if I search the active directory (I can click 'search active directory' and then select 'computers' and then Find Now, and all of the computers will appear). However, the computers are not listed in the network browser on any of our computers (Win XP, Win7, Linux, etc) which are connected to the domain. DC is running Windows Server 2008 (Windows Server Standard) with a configured DNS and DHCP server. All of the IPs on our local network are static IPs, although I can't see how that would make a difference. I can still connect to computers on the network via \\computer_name, but I cannot browse them in 'network' or in 'my network places'. The computer browser service is not started on the DC, but I tried starting that and it had no effect. DC currently has the firewall configured as 'off' to try to debug this problem. Thanks in advance

  • new ubuntu server installation - java server not receiving packets

    - by James
    I have developed a Java server which listens for UDP packets which come from mobile devices. At the moment, it works correctly if I run my Server on my windows PC. I can receive and respond to the UDP packets sent from my phone (over 3g, not wifi). However, I am trying to run the Server on a different computer which I found lying around my house. I have basically done a clean install of Ubuntu Server edition, updated it, installed the java run time environment and configured port forwarding to allow connections on the appropriate port. I have also tried to disable the firewall. The problem is, it doesn't appear as if the server is receiving any packets and I've exhausted my brain thinking on how to solve/debug the problem. Can anyone suggest to me what the problem might be? or more likely something I can do to help me find out more information about what is going wrong.

  • Shell script for replacing string in all PHP-files, for each user

    - by Mads Skjern
    Each user has some php-files using a shared database commondb. I want to iterate over all users (in users.csv), and in their home folder (e.g. /home/joe) find all php files recursively, and replace each occurrence of "commondb" with their own databasename, e.g. "joedb" for "joe". I have tried the following: #!/bin/bash # Execute like this: # bash localize.bash users.csv OLDIFS=$IFS IFS="," while read name dummy do echo $name find /home/${name} -name '*.php' -exec sed -i '' 's/commondb/${name}db/g' "{}" \; done < $1 IFS=$OLDIFS for users.csv joe, Joe J george, George G It does not fail, but the files are unchanged. I am quite weak in bash, and I can't figure out how to debug it :/ Can my script be fixed to work?

  • Install-SPSolution : This solution contains no resources scoped for a Web appli cation and cannot be deployed to a particular Web application

    I have a PowerShell script that deploys about 12 web parts. They have all been created through Visual Studio 2010 and are being deployed to SharePoint 2010. I am getting the following error when running Install-SPSolution for one of my web parts: Install-SPSolution : This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application. Can someone help me debug this? Every other Install-SPSolution command uses -AllWebApplications, and I do not want to specify the web application directly using -URL. Here is the command that is breaking (this is the same command used to successfully deploy all 11 other web parts): Install-SPSolution –Identity PortalSelector.wsp -AllWebApplications -GACDeployment

  • Upgrading Fedora 16 to 17 with crypted LVM

    - by nijansen
    As the title suggests, I want to upgrade Fedora 16 to the Fedora 17 Alpha build, but I am struggling to do so because of my crypted HDD. To avoid the hustle of CD-ROM or USB install, I thought the preupgrade would be a good idea. It downloads the stuff, stores an image somewhere and creates an entry in my boot manager. When I choose to upgrade from the boot manager it crashes halfway through because it can not access any of the prepared files (because it's crypted) and hands me a debug console. Unfortunately, this case apparently is not covered by the Fedora troubleshooting advice, at least I was not able to find anything there. I would guess I have to mount my HDD manually, but 1) how? and 2) how do I resume the upgrade afterwards? I would really appreciate a push in the right direction.

  • Strange Unclearable Cache Issue with Gmail and Google Apps

    I am having a strange issue with Gmail and Google Apps... have a look at this screenshot: http://cld.ly/f51ume notice the missing images for the rounded corners? Well this is not such a problem but something similar to a cache issue is causing this as well as no background image, but MOST IMPORTANTLY chat and other "clickable" features aren't working. I've already cleared my cache multiple times and quit and re-started Firefox with no change. Everything is OK in other browsers. Any other debug suggestions?

  • SSH not working after Restoring Running-Config to a Replacement Cisco Router

    - by Kyle Brandt
    One of my Cisco routers died over the weekend, Cisco sent the replacement and I restored the the config using copy tftp: running-config. Everything seems to work fine but I can no longer ssh into the router (I can telnet). The connection is refused, so it isn't listening on port 22 it seems like. I had previously backed up the config by just doing ssh router 'show run' > backup_config from my workstation. So: Is there anything wrong with my method of backup vs copy running-config tftp:? I know I haven't given any debug information, but is there something typical I need to do to get ssh working?
