  • Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

    - by Keeper Hood
    I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

  • nginx rewrite or internal redirection cycle

    - by gyre
    Im banging my head against a table trying to figure out what is causing redirection cycle in my nginx configuration when trying to access URL which does not exist Configuration goes as follows: server { listen 127.0.0.1:8080; server_name .somedomain.com; root /var/www/somedomain.com; access_log /var/log/nginx/somedomain.com-access.nginx.log; error_log /var/log/nginx/somedomain.com-error.nginx.log debug; location ~* \.php.$ { # Proxy all requests with an URI ending with .php* # (includes PHP, PHP3, PHP4, PHP5...) include /etc/nginx/fastcgi.conf; } # all other files location / { root /var/www/somedomain.com; try_files $uri $uri/ ; } error_page 404 /errors/404.html; location /errors/ { alias /var/www/errors/; } #this loads custom logging configuration which disables favicon error logging include /etc/nginx/drop.conf; } this domain is a simple STATIC HTML site just for some testing purposes. I'd expect that the error_page directive would kick in in response to PHP-FPM not being able to find given files as I have fastcgi_intercept_errors on; in http block and nave error_page set up, but I'm guessing the request fails even before that somewhere on internal redirects. Any help would be much appreciated.

  • I had a power outage. Now MySQL's lock file won't go away. What do you suggest?

    - by jasonspiro
    I do freelance IT consulting for various clients, both in Toronto, Canada, and worldwide. A client recently experienced a power failure. Now they've been having various problems with a Slackware 12.0.0 machine which also acts as a DNS server. One problem is that they can't log into phpMyAdmin. I tried stopping and restarting MySQL. But even when MySQL is stopped, the lock file stays around. jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop Shutting down MySQL. SUCCESS! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop ERROR! MySQL manager or server PID file could not be found! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql status ERROR! MySQL is not running, but lock exists jasonspiro@cybertron:~$ ls -l /var/lock/subsys/mysql -rw-r--r-- 1 root root 0 2012-07-05 16:18 /var/lock/subsys/mysql Why is MySQL's lock file hanging around despite the fact that MySQL isn't running? Can I simply stop MySQL, delete the lock file, and start MySQL again? Are there any other steps that I should take next, or nothing?

  • Networking lost after update from Debian Wheezy to Jessie

    - by Charaf
    I am currently setting a Virtual Machine for development purposes. I did a big part of this configuration under Wheezy, but I need some debs that were available only on Jessie. So, I've updated the sources.list and did a dist-upgrade. Everything went well, but after the reboot, I noticed that I lost all the networking. Repositories are unreachable, as well as a simple ping google.fr returns nothing. What can I do to quickly restore networking so that I can continue my working. I have a poor connexion and can not afford to download the whole install DVDs. root@vm~# ifconfig lo Link encap:Boucle locale inet adr:127.0.0.1 Masque:255.0.0.0 adr inet6::1/128 Scope:Hôte UP LOOPBACK RUNNING MTU:65536 Metric 1 RX packets:452 errors:0 dropped:0 overruns:0 frame:0 TX packets:452 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:0 RX bytes:164238 (160.3 KiB) TX bytes:164238 (160.3 KiB) root@vm~# I am running VMware 1.0.1 build 1379776 and the last update of Jessie (debian 3.14.4-1) Please help.

  • Checksum for Protecting Read-Only Documents

    - by Kim
    My father owns a small business and has to hand over several year's worth of financial documents to his insurance's auditor. He's asked me to go through and make sure everything is "read-only" so the data (the files) absolutely, positively cannot be modified or manipulated (he's a bit paranoid). We're talking about 20,000 documents (emails, spreadsheets, etc.). My first inclination was to place everything inside of one root folder ("mydadsdocs/") and then write a script that recursively traversed its directory subtree and set the file permissions to read-only. But then I got to thinking: that's a lot of work for me to do to satisfy an old man who is just being paranoid, and afterall, if someone really wanted to modify a read-only file, it would be pretty easy to change file permissions anyways, soo.... Is there like a checksum I could run on the root folder, something that was very quick and easy, and that would basically "stamp" the data in that folder so if someone did change it, my father would have someone of knowing/proving it? If so, how? If not, any other recommendations that are quick, cheap (free) and effective?

  • Mounted HDD not having enough permissions from Apache/PHP

    - by Dan
    Piwigo gallery, on apache and php. The root system is a RAID 128GB. /var/www/html is on the root file system. Mounted the 320GB hdd to /var/www/html/320 using defaults, it's an ext4 fs. Put a symlink to it in /var/www/html/galleries which is read by the gallery script so I can upload images to there, then click sync. It gives me the error: [./galleries/] PWG-ERROR-NO-FS (File/directory read error) PWG-ERROR-NO-FS: The file or directory cannot be accessed (either it does not exist or the access is denied) chmod 777 set on /dev/sdb1, /var/www/html, and /var/www/html/320 as well as the symlink galleries too. All recursive. chown apache:apache to everything too. PHP just can't read/write to it. I tried with and without the symlink, I've tried everything I can think of. Nothing. Any ideas how I can give apache/php permission to read/write to this drive? With 777 permissions all around it should already be able to.

  • Cisco ASA5505 won't sync with NTP

    - by Martijn Heemels
    Today I noticed that the clock my Cisco ASA 5505 firewall was running about 15 minutes late, which surprised me since I've set up the NTP client. My two NTP servers 10.10.0.1 and 10.10.0.2 are virtualized Windows Server 2008 R2 domain controllers, and both have the correct time. As shown below, the ASA knows about the two servers, can ping them and seems to poll them periodically, so I suppose it can reach them both. The ASA claims its time source is NTP, however the clock is unsynchronized. Neither host is marked as synced. Result of the command: "ping 10.10.0.1" Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.0.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms Result of the command: "sh ntp ass" address ref clock st when poll reach delay offset disp ~10.10.0.1 .LOCL. 1 78 1024 377 0.5 643.69 17.0 ~10.10.0.2 10.10.0.1 2 190 1024 377 0.9 655.91 58.4 * master (synced), # master (unsynced), + selected, - candidate, ~ configured Result of the command: "sh ntp stat" Clock is unsynchronized, stratum 16, no reference clock nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6 reference time is 00000000.00000000 (07:28:16.000 CEST Thu Feb 7 2036) clock offset is 0.0000 msec, root delay is 0.00 msec root dispersion is 0.00 msec, peer dispersion is 0.00 msec Result of the command: "sh clock detail" 10:33:23.769 CEDT Tue Jun 26 2012 Time source is NTP UTC time is: 08:33:23 UTC Tue Jun 26 2012 Summer time starts 02:00:00 CEST Sun Mar 25 2012 Summer time ends 03:00:00 CEDT Sun Oct 28 2012 I've tried the basic steps of manually setting the time and removing and adding the timeservers, to no avail. My ASA's ntp config is simply: ntp server 10.10.0.1 ntp server 10.10.0.2 Do I need to enable authentication to use a Windows NTP server? Any thoughts?

  • Setting up subdomain to respond on :443 with apache2

    - by compucuke
    I read through some guides on this and I believe it is possible to have apache respond to a subdomain through ssl. I have domain.com responding on 80 and I do not need domain.com responding on 443. Rather, the only use I have for ssl is for the subdomain sub.domain.com. So my site should be http://domain.com http://www.domain.com https://sub.domain.com https://www.sub.domain.com My CNAME records are as follows sub.domain.com xxx.xx.xx.xxx *.sub.domain.com xxx.xx.xx.xxx The A record exists but should not matter for the example. I set up a separate config file in sites-enabled for sub.domain.com NameVirtualHost xxx.xx.xx.xxx:443 <VirtualHost xxx.xx.xx.xxx:443> SSLEngine on SSLStrictSNIVHostCheck on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:-MEDIUM ServerAlias sub.domain.com DocumentRoot /usr/local/www/ssl/documents/ SSLCertificateFile /root/sub.domain.com.crt SSLCertificateKeyFile /root/sub.domain.com.key Alias /robots.txt /usr/local/www/ssl/documents/robots.txt Alias /favicon.ico /usr/local/www/ssl/documents/favicon.ico Alias /js/libs /usr/local/www/ssl/documents/js/libs Alias /media/ /usr/local/www/documents/media/ Alias /img/ /usr/local/www/ssl/documents/img/ Alias /css/ /usr/local/www/ssl/documents/css/ <Directory /usr/local/www/ssl/documents/> Order allow,deny Allow from all </Directory> WSGIDaemonProcess sub.domain.com processes=2 threads=7 display-name=%{GROUP} WSGIProcessGroup sub.domain.com WSGIScriptAlias / /usr/local/www/wsgi-scripts/script.wsgi <Directory /usr/local/www/wsgi-scripts> Order allow,deny Allow from all </Directory> </VirtualHost> Now, it is important to mention that https://domain.com responds with what I have running from script.wsgi above instead of on https://sub.domain.com. It does not respond to sub.domain.com. checking https://sub.domain.com causes a 105 error. This is a DNS error but I am convinced the DNS does not have a problem with the CNAME records, they just point to my IP. Am I doing something that Apache can not do?

  • Help setting up a secondary authoritative DNS server.

    - by GLB03
    We have three Authoritative DNS servers and three recursive/caching DNS servers on my campus. Authoritative servers DNS1- Windows 2003 DNS2- Old Red Hat ----- Replacing w/ newer version DNS3- Windows 2008 (I installed) Caching and Recursive resolvers servers Server1- Windows 2003 Server2- CentOS 5.2 (I installed) Server3- CentOS 5.3 (I installed) I am replacing DNS2 with a newer Red Hat version, but have no documentation on how it was implemented. I have setup caching and windows authoritative servers, but not a linux secondary authoritative server. I have a perl script from the original server that pulls data from our DNS1 server. We use DJBDNS and TinyDNS on our linux servers. Our Network Engineer says the DNS2 server I am replacing is an authoritative server that doesn't need to be caching, but the only instructions I see is for an Authoritative server that does caching as well. Can someone point me in the right directions. I thought I was on the right track with using these instructions but when I query my new dns server I get "No response from server", I have temporarily disabled iptables to eliminate it from being an issue. ps -aux | grep dns avahi 3493 0.0 0.2 2600 1272 ?

  • cannot log into mysql locally

    - by Lostsoul
    When I try to log into mysql locally using the command: mysql -u root -p I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) I can access the server remotely(not as root) and my web pages are using the mysql fine, but locally I cannot log on(which I need because I need to create some users). Only change I made was to attach another drive to the server and move the sql data there. Here's my.cnf [mysqld] datadir=/media/ephemeral0/data/mysql socket=/media/ephemeral0/data/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # adding more config skip-external-locking long_query_time=1 slow_query_log slow_query_log_file=/var/log/log-slow-queries.log log-bin=mysql-bin server-id= 1 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid myisam_recover_options I read I need to edit the socket info in my.cnf to make sure it points to the right socket file..I double checked and the file exists(although it starts with an S when I do ls -l "srwxrwxrwx 1 mysql mysql 0 Jun 21 03:43 mysql.sock"). I'm not really sure how to resolve this. I have tried to reboot and ran yum update to make sure I was running the latest packages. Please help!

  • How to set up multiple DNS servers on an intranet

    - by Brent
    We have an Active Directory network, with a mixture of Windows DNS, linux BIND servers, and want to use OpenDNS as our external DNS provider. I am wondering What is the best way to set up these servers (regarding forwarders, recursion, etc.)? Active Directory is our main internal DNS for our domain, and has 3 redundant servers. DHCP and all our servers use these as their DNS servers. Then we have a legacy AD server from an old network that is still authoritative for a bunch of domains. Finally, we have a couple of Linux Bind servers that are authoritative for a bunch of websites we host. Should our main AD servers point to our legacy AD server, which points to one of our BIND servers, which points to the other BIND server, which finally points out to openDNS? Or should our main AD servers point to all of these directly? - or is there a better option? What happens if a domain is listed in 2 places? Does DNS process the forwarders in order? What about root servers - if I want to use OpenDNS for "everything else", do I just list them as the last forwarders, and delete the root servers from all my DNS servers? How does recursion work - in this scenario, should I be using recursion or not?

  • How to prioritize openvpn traffic?

    - by aditsu
    I have an openvpn server, with one network interface. VPN traffic is extremely slow. I tried to do traffic control with this configuration (currently): qdisc del dev eth0 root qdisc add dev eth0 root handle 1: htb default 12 class add dev eth0 parent 1: classid 1:1 htb rate 900mbit #vpn class add dev eth0 parent 1:1 classid 1:10 htb rate 1500kbit ceil 3000kbit prio 1 #local net class add dev eth0 parent 1:1 classid 1:11 htb rate 10mbit ceil 900mbit prio 2 #other class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 1000kbit prio 2 filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 1194 0xffff flowid 1:10 filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match ip dst 192.168.10.0/24 flowid 1:11 qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 qdisc add dev eth0 parent 1:11 handle 11: sfq perturb 10 qdisc add dev eth0 parent 1:12 handle 12: sfq perturb 10 But it's still extremely slow. I have an imaps connection that keeps transferring data continuously (I successfully limited the rate) but with openvpn I can't seem to get more than about 100kbit/s The internet connection speed is about 3mbit/s (symmetric) What could be the problem? Does the sport filter work for udp?

  • How can I avoid an error in this .htaccess file?

    - by mipadi
    I have a blog. The blog is stored under the /blog/ prefix on my website. It has the usual URLs for a blog, so articles have URLs in the format /blog/:year/:month/:day/:title/. First and foremost, I want to automatically redirect visitors to the www subdomain (in case they leave that off), and internally rewrite the root URL to /blog/, so that the front page of the blog appears on the front page of the site. I have accomplished that with the following set of rewrite rules in my .htaccess file: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] That works fine. The problem is that the front page of the blog now appears at two distinct URLs: / and /blog/. So I'd like to redirect the /blog/ URL to the root URL. Initially I tried to accomplish this with the following set of rewrite rules: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ / [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But that gave me an infinite redirect (maybe because of the preceding rule?). So then I tried this set: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ http://www.monkey-robot.com/ [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But I got a 500 Internal Server Error with the following log message: Invalid command '[R,L]', perhaps misspelled or defined by a module not included in the server configuration What gives? I don't think [R,L] is a syntax error.

  • How to enable error log in lighttpd properly?

    - by Tomaszs
    I have a Centos 5 system with Lighttpd and fastcgi enabled. It does log access but does not log errors. I have Internal Server Error 500 and no info in log and when I try to open not -existing file also - no info in error log. How to enable it properly? Below is list of modules that I've enabled: server.modules = ( "mod_rewrite", "mod_redirect", "mod_alias", # "mod_access", # "mod_cml", # "mod_trigger_b4_dl", # "mod_auth", "mod_status", "mod_setenv", "mod_fastcgi", # "mod_webdav", # "mod_proxy_core", # "mod_proxy_backend_fastcgi", # "mod_proxy_backend_scgi", # "mod_proxy_backend_ajp13", # "mod_simple_vhost", # "mod_evhost", # "mod_userdir", # "mod_cgi", # "mod_compress", # "mod_ssi", # "mod_usertrack", # "mod_expire", # "mod_secdownload", # "mod_rrdtool", "mod_accesslog" ) Here are setting of debugging: ## enable debugging #debug.log-request-header = "enable" #debug.log-response-header = "enable" #debug.log-request-handling = "enable" debug.log-file-not-found = "enable" #debug.log-condition-handling = "enable" Setting of path to error and access log: ## where to send error-messages to server.errorlog = "/home/lxadmin/httpd/lighttpd/error.log" #### accesslog module accesslog.filename = "/home/lxadmin/httpd/lighttpd/ligh.log" Settings of fastcgi: fastcgi.debug = 1 fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 12, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "2", "PHP_FCGI_MAX_REQUESTS" => "500" ) ))) And in included config file I have: server.errorlog = "/home/httpd/mywebsite.com/stats/mywebsite.com-error_log" What comes to log files: /home/httpd/mywebsite.com/stats/ -rw-r--r-- 1 apache apache 5173239 May 16 11:34 mywebsite.com-custom_log -rwxrwxrwx 1 root root 0 Mar 27 2009 mywebsite.com-error_log /home/lxadmin/httpd/lighttpd/ -rwxrwxrwx 1 apache apache 2184 Apr 22 22:59 error.log -rwxrwxrwx 1 apache apache 6088621 May 16 11:26 ligh.log I gave error logs chmod 777 for a try to check if it's the issue, but apparently it's not. So my question is: what to do to have error log enabled?

  • copying an lvm partition to a smaller disk, and renaming volume groups.

    - by dlamblin
    I was trying to shrink a vmdk (VMWare disk image) file to be as small as possible, and found two recommendations. The first is to cat /dev/zero into the fs then delete it, and run VMWare tools' shrink. This works okay. The second is to copy everything into a new vmdk. I went the second route. I did not use dd because I actaully want to use as few blocks as possible, instead of having a block-by-clok copy. Any unlinked files will still have blocks that aren't zeroed out. Secondly the centos image was mostly lvm, except for the boot partition, and my target was going to be 4gb instead of 8gb. I did use dd for the first 40mb to get the boot blocks and partition copied. I then used parted to create an identical primary boot, and smaller primary lvm. Then I used pvcreate on that device sdb2, vgcreate, and lvcreate to create a root and swap. I used mkfs.ext3fs on the root partition and then rsync -av / /2root excluding /proc /sys /2root /dev. So far everything went fine. My problem is that: The result is 2.7 GB while the source was 2.1 GB. This is weird to me. The second vgroup is called VolGroup01, while the original was called VolGroup00. How can I rename the VolGroup01 to VolGroup00 and swap it out after all this?

  • Flushing iptables broke my pipe, how can I save my instance?

    - by Niels
    I was setting up my iptables when I performed a iptables -F and my ssh pipe broke. This is the last output of my session: root@alfapaints:~# iptables -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state NEW,ESTABLISHED tcp dpt:2222 ACCEPT tcp -- li465-68.members.linode.com anywhere state NEW,ESTABLISHED tcp dpt:nrpe ACCEPT tcp -- anywhere anywhere tcp dpt:9200 state NEW,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:http state NEW,ESTABLISHED ACCEPT udp -- anywhere anywhere udp spt:domain Chain FORWARD (policy DROP) target prot opt source destination Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state ESTABLISHED tcp spt:2222 ACCEPT tcp -- anywhere anywhere state ESTABLISHED tcp spt:nrpe ACCEPT tcp -- anywhere anywhere tcp spt:9200 state ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp spt:http state ESTABLISHED ACCEPT udp -- anywhere anywhere udp dpt:domain root@alfapaints:~# iptables -F Write failed: Broken pipe I tested my connection just before and I was able to connect with ssh. Now I did a nmap scan and not a single port is open anymore. I know my VPS is running on VMWare ESXi, could a reboot help? Or if not could I attach and mount the disk to another vm to save the data? Does anybody have some advise? And maybe an explanation what happend or what could have cause my pipe to break? ps: I didn't save my rules on the config directories of iptables. But used a file I stored in ~/rules.config to apply my rules like this: iptables-restore < rules.config So probably a reboot would help? Thanks a lot in advance.

  • Apache /server-status/ gives a 404 not found

    - by kapshure
    I am trying to solve a problem where Apache stats aren't displaying correctly in Munin. I've ran through quite a bit of checks and tests regarding Munin setup, but I think my issue is related to Apache, but my skill set there is lacking. first, system info: monitored server CentOS 5.3 kernel 2.6.18-128.1.1.el5 Apache/2.2.3 "server-status" directive in httpd.conf (i've cross-compared this with another system that i did a successful parallel install of Munin on, correctly showing Apache stats, and the directive below is the same for both) ExtendedStatus On <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 </Location> ran lynx http://localhost/server-status got HTTP/1.1 404 taking a look at Apache access_log: 127.0.0.1 - - [13/Oct/2010:07:00:47 -0700] "GET /server-status HTTP/1.0" 404 11237 "-" "Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 OpenSSL/0.9.8e-fips-rhel5" mod_status is also loaded: % grep "mod_status" /etc/httpd/conf/httpd.conf LoadModule status_module modules/mod_status.so iptables is turned off also i did notice that the ownership status on httpd.conf on this system is root.root.. whereas the system that is displaying correctly is apache.www -- not certain that this matters?? its got to be permission issue, but i'm not certain where the permissions are messed up. any thoughts on why the test of server-status is giving me a 404?

  • sysctl.conf not running on boot

    - by Brian
    At what point is sysctl.conf supposed to be read during boot, and why might it not be running? I have the following settings which are not being applied when I reboot: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-filter-pppoe-tagged = 0 net.bridge.bridge-nf-filter-vlan-tagged = 0 fs.nfs.nlm_udpport = 32768 fs.nfs.nlm_tcpport = 32768 The first section is needed for KVM bridging, and the second is to run the NFS lock manager on a known port. However, after booting, these values have not taken effect. If I run sysctl -p, then they do. This wouldn't be a huge issue, except that I can't figure out how to restart the lock manager without rebooting. I would really like to know why sysctl.conf isn't working at boot, but I'd settle for just being able to restart the lock manager. This is on Ubuntu server 10.04.2, kernel 2.6.32-31-server. I know some daemons check the permissions on their config files and refuse to work if they're too permissive, but sysctl.conf is 644 root:root, which I'm pretty sure is the default.

  • VNC failure on Xen

    - by BCable
    The following config works and creates a good VM in Xen: # Kernel Setup kernel = "/boot/vmlinuz-2.6.18.8-xenU" # Memory memory = "256" # Disk disk = [ "file:/opt/xen/domains/110/sda1.img,sda1,w", "file:/opt/xen/domains/110/swap.img,sda2,w" ] # container name name = "110" hostname = "boo" # Networking vif = ["type=ieomu, bridge=xenbr0"] # VNC vnc = 1 #vfb = [ 'type=vnc,vncdisplay=2,vnclisten=0.0.0.0,vncpasswd=110' ] # Behavior Settings root = "/dev/sda1" extra = "fastboot" But when I uncomment the VFB line, I get the following error after it hangs for at least 30 seconds: [root@customer 110]# xm create boo.cfg Using config file "./boo.cfg". Error: Device 0 (vkbd) could not be connected. Hotplug scripts not working. Any ideas? Part two of this question: Sometimes it actually works, and a port is opened. When this happens, nmap shows the VNC ports open and I can connect via the VNC client, but it just hangs at "Connection established." and no VNC display shows up. I've tried multiple VNC clients (TightVNC, TightVNC Java Console, RealVNC), but they all fail to connect. Does VNC through Xen require X to be started in order to function? I was under the impression that it would show the console screen, so I'm confused as to why all these issues are occurring. Thanks!

  • Is there a quick way of undoing a folder change in Far Manager?

    - by Johannes Rössel
    I love Far Manager. However, it has a feature to quickly go to the root directory of a drive with Ctrl+\. I do sometimes need and use this feature, but more frequently I use Ctrl+? to quickly insert the file name under the cursor into the command line. As it so happens, the ? key is located dangerously close to \ which is why I sometimes erroneously go the root directory (which then is doubly unfortunate since I originally wanted to work with a file in the directory I was in). Now I could probably just redefine Ctrl+\ to do nothing, although I still sometimes need that (can be replicated with a quick cd\, though). But Windows Explorer, in the wake of the WWW, provided us with a handy directory history and two separate ways of navigating backwards: backwards through the history and backwards through the hierarchy. Is there something quick and easy to get back to the folder I were in? This is less of an issue in C:\Users\Me (still nagging) but more so in deeper hierarchies.

  • Nginx Not Passing URL Parameters

    - by jmccartie
    Messing around with Nginx ... for some reason, it looks like none of my URL parameters are being passed. My homepage loads fine, but a URL like "http://mysite.com/more.php?id=101" throws errors, saying that the ID is an undefined index. I'm assuming this is something basic I'm missing in a conf file. Some info: conf.d/virtual.conf server { listen 80; server_name dev.mysite.com; index index.php; root /var/www/dev.mysite.com_html; location / { root /var/www/dev.mysite.com_html; } location ~ \.php(.*)$ { fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME /var/www/wap/dev.mysite.com_html/$fastcgi_script_n ame; fastcgi_index index.php; include /etc/nginx/fastcgi_params; } } Error log: 2009/06/22 11:44:21 [notice] 16319#0: start worker process 16322 2009/06/22 11:44:28 [error] 16320#0: *1 FastCGI sent in stderr: "PHP Notice: Undefined index: id in /var/www/dev.mysite.com_html/more.php on line 10 Thanks in advance.
