  • How to echo current document.title with Firefox Vimperator -> autocmd?

    - by shox
    When I try to do this :autocmd LocationChange .* echo document.title the first page that gets displayed makes no echo. If I proceed to the next tab, the title of the last tab gets echoed. Does anybody know how I can get for every landing on the page the title echoed instantly instead of when "leaving" the tab? And it only works every two times. If I go through my tabs 1,2,3,4,5,6,7,8 (next tab) the output will be (being at 1 currently) _blank Title of 1 _ Title of 3 _ Title of 5 _ Title of 7 _ (now being at tab 8) But I want Title of 1 Title of 2 ... Any ideas?

  • "service"-command and environment variables

    - by varesa
    I am trying to start a service that requires a env. variable to be set to certain path. I set this variable in "/etc/profile.d/". However when I start this service using the service command, it doesn't work. man service: service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. So it seems that service is removing my variables. How should I set the variables up to keep them from being removed. Or is that something i should not do. I could start the service manually using the init-scripts, or even hardcode the path into the script, but I'd like to know how to use it with the service command.

  • DNS propagation

    - by Paddington
    I have 1 primary DNS server (ns1.mydomain.com) running on Fedora and 2 secondary ones (ns2 and ns3). DNS changes made on my web servers first goes to the primary name server and then propagates to the secondary servers. After making a DNS change on a domain on the web server, I can't see the new dns information on my ns1 when I perform: dig @ns1 A blahblah.com I then went to the master records on the names server (uses named) in the directory /var/named/run-root/var/named/masters and I see the A record has been updated appropriately. Tailing the logs /var/log/messages is not showing any errors. What could be the issue?

  • VFS and FS i-node difference

    - by gaffcz
    What is the difference between VFS i-node and FS (e.g. EXT) i-node? Is it possible that EXT i-node is persistent (contains/points to data blocks), but VFS i-node is created just in i-node cache after read/use of EXT i-node? Or the VFS i-node is just an image of FS i-node (it's the same) and i-nodes in those systems, which are not working with i-nodes (e.g. FAT, NTFS) has to be emulated (HOW?) to allow VFS work with those FS like they would support i-nodes?

  • Why does't rsync use delta-transfer for local files ?

    - by o_O Tync
    I have a big iso image which is currently being downloaded by a torrent client with space-reservation turned on: that means, file size is not changing while some chunks in in (4 Mib) are constantly changing because of a download. At 90% download I do the initial rsync to save time later: $ rsync -Ph DVD.iso /some/target/ sending incremental file list DVD.iso 2.60G 100% 40.23MB/s 0:01:01 (xfer#1, to-check=0/1) sent 2.60G bytes received 73 bytes 34.59M bytes/sec total size is 2.60G speedup is 1.00 Then, when the file's fully downloaded, I rsync again: total size is 2.60G speedup is 1.00 Speedup=1 says delta-transfer was not used, although 90% of the file has not changed. Why?!

  • Is it possible to install Photomatix under wine?

    - by chris
    Is it possible to install Photomatix under wine? I'm running Ubuntu 9.04, and I've tried both the default download and the embedded .net version. The first attempts to install the .net framework 1.1, and fails, while the 2nd appears to install but won't run. After a bit of googling, er, binging, I tried adding the .net 2.0 runtime via winetricks, and now it appears to install OK, but still won't run - either from the wine menu, or from the command line. Is it possible? What do I need to do?

  • nagios ldap-group based front end login permission issues

    - by Eleven-Two
    I want to grant users access to the nagios 3 core frontend by using an active directory group ("NagiosWebfrontend" in the code below). The login works fine like this: AuthType Basic AuthName "Nagios Access" AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthLDAPURL "ldap://ip-address:389/OU=user-ou,DC=domain,DC=tld?sAMAccountName?sub?(objectClass=*)" AuthLDAPBindDN CN=LDAP-USER,OU=some-ou,DC=domain,DC=tld AuthLDAPBindPassword the_pass Require ldap-group CN=NagiosWebfrontend,OU=some-ou,DC=domain,DC=tld Unfortunately, every nagios page just shows "It appears as though you do not have permission to view information for any of the services you requested...". I got the hint, that I am missing a contact in nagios configuration which is equal to my login, but creating one with the same name as the domain user had no effect on this issue. However, it would be great to find a solution without manually editing nagios.conf for every new user, so the admins could grant access to nagios by just putting the user to "NagiosWebfrontend" group. What would be the best way to solve it?

  • chroot for unsecure programs execution

    - by attwad
    Hi, I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well. To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose). Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.py All of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies). I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script) Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script? Thank you very much.

  • Wrap app with dynamic libraries into one large static app

    - by progo
    I have an old program that kind of depends on older dynamic libraries. They tend to get upgraded easily with distro's updates. I figured that there would be a script with using ldd that would gather the libs needed and create one bigger, statically linked application that wouldn't break so easily. If I could do this, alot of older KDE libraries could be removed from my system and easen my life. Thanks!

  • Changed array composition, mdadm --detail still shows the old array size

    - by Prody
    I have a machine with 8 disks. I installed it with my hoster's install automation (it's OVH, I don't have physical access to it). The machine installed correctly, but it made an array that I wanted to change. It created a raid5 array across 5/8 disks and I've changed it to raid10 across 8 disks. I've done this by first --stopping the old array and then --creating the new array. It warned me that a previous array was there, but I chose to continue. So it created the array, spent 10ish hours syncing it and now that it's ready I get this strange behavior: When I fdisk p on it, I see the correct size. But when I mdadm --detail it I see the old array's size even tho I get the new composition and level. When I try to pvcreate on it, i get the old size again for some reason. Did I have to do something else? Did I miss something?

  • Best open source server notification software

    - by Adam Evers
    I am looking for an open source notification/monitoring software which will work much like growl does with a mac. It would be awesome if I could receive certain messages to my mac computer from my server when lets say it restarts or some predefined error happens etc. Anyone know of anything like that? I know of Nagios but I am thinking not as complex.

  • Decrease in disk performance after partitioning and encryption, is this much of a drop normal?

    - by Biohazard
    I have a server that I only have remote access to. Earlier in the week I repartitioned the 2 disk raid as follows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/sda1_crypt 363G 1.8G 343G 1% / tmpfs 2.0G 0 2.0G 0% /lib/init/rw udev 2.0G 140K 2.0G 1% /dev tmpfs 2.0G 0 2.0G 0% /dev/shm /dev/sda5 461M 26M 412M 6% /boot /dev/sda7 179G 8.6G 162G 6% /data The raid consists of 2 x 300gb SAS 15k disks. Prior to the changes I made, it was being used as a single unencrypted root parition and hdparm -t /dev/sda was giving readings around 240mb/s, which I still get if I do it now: /dev/sda: Timing buffered disk reads: 730 MB in 3.00 seconds = 243.06 MB/sec Since the repartition and encryption, I get the following on the separate partitions: Unencrypted /dev/sda7: /dev/sda7: Timing buffered disk reads: 540 MB in 3.00 seconds = 179.78 MB/sec Unencrypted /dev/sda5: /dev/sda5: Timing buffered disk reads: 476 MB in 2.55 seconds = 186.86 MB/sec Encrypted /dev/mapper/sda1_crypt: /dev/mapper/sda1_crypt: Timing buffered disk reads: 150 MB in 3.03 seconds = 49.54 MB/sec I expected a drop in performance on the encrypted partition, but not that much, but I didn't expect I would get a drop in performance on the other partitions at all. The other hardware in the server is: 2 x Quad Core Intel(R) Xeon(R) CPU E5405 @ 2.00GHz and 4gb RAM $ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 32 Lun: 00 Vendor: DP Model: BACKPLANE Rev: 1.05 Type: Enclosure ANSI SCSI revision: 05 Host: scsi0 Channel: 02 Id: 00 Lun: 00 Vendor: DELL Model: PERC 6/i Rev: 1.11 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: HL-DT-ST Model: CD-ROM GCR-8240N Rev: 1.10 Type: CD-ROM ANSI SCSI revision: 05 I'm guessing this means the server has a PERC 6/i RAID controller? The encryption was done with default settings during debian 6 installation. I can't recall the exact specifics and am not sure how I go about finding them? Thanks

  • pcfg_openfile: unable to check htaccess file, ensure it is readable

    - by rxt
    After moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however. The setup is a bit complex, as follows: I have Ubuntu 10.4 as development machine, trying to mimic the server as much as possible We use Eclipse + SVN and I create all projects in a local folder under my user account In /var/www-vhosts I create folders for each vhost, like this one: test.localhost test.local/index.php: includes the index file of the project test.local/.htaccess is a dynamic link to the htaccess file in a project subfolder I get the following error in the apache error log: [Thu Jul 08 15:55:56 2010] [crit] [client 127.0.0.1] (13)Permission denied: /var/www-vhosts/test.localhost/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable The problem seems to be the .htaccess file, or the link to it. When I empty the htaccess, nothing changes When I remove the link, the index-include produces some output (in the apache error log) When I remove the link and replace it with the actual file, I get another error: [Thu Jul 08 16:47:54 2010] [error] [client 127.0.0.1] Symbolic link not allowed or link target not accessible: /var/www-vhosts/test.localhost/test I'm lost here, don't know what to do next. Do you have any ideas what I can try? This setup has worked before, but I don't know what is different now.

  • proftpd initial directory for each user

  • How is network mounted software executed?

    - by CptSupermrkt
    I would like to understand how network mounted software works. For example, at my place of work, we have a software server. Each client machine (hundreds of them) automatically mounts directories from the software server on boot. For example, a program like Matlab is installed just once on the software server, but each client machine can start up an instance of Matlab. What is going on under the hood? Let's say I run /opt/bin/matlab and /opt/ is mounted from the software server, what happens when I press Enter to execute matlab on a client machine? The process is on the client machine, and I've already narrowed down that there isn't any implicit or hidden file transfer (i.e. copying matlab to my machine temporarily for that session) by running matlab on a computer with nearly zero disk space (i.e. not enough room to transfer). Since Matlab was installed on the server, how is my client computer executing it? What mechanism is controlling this? What is happening behind the scenes?

  • Do background processes get a SIGHUP when logging off?

    - by Massimo
    This is a followup to this question. I've run some more tests; looks like it really doesn't matter if this is done at the physical console or via SSH, neither does this happen only with SCP; I also tested it with cat /dev/zero > /dev/null. The behaviour is exactly the same: Start a process in the background using & (or put it in background after it's started using CTRL-Z and bg); this is done without using nohup. Log off. Log on again. The process is still there, running happily, and is now a direct child of init. I can confirm both SCP and CAT quits immediately if sent a SIGHUP; I tested this using kill -HUP. So, it really looks like SIGHUP is not sent upon logoff, at least to background processes (can't test with a foreground one for obvious reasons). This happened to me initially with the service console of VMware ESX 3.5 (which is based on RedHat), but I was able to replicate it exactly on CentOS 5.4. The question is, again: shouldn't a SIGHUP be sent to processes, even if they're running in background, upon logging off? Why is this not happening? Edit I checked with strace, as per Kyle's answer. As I was expecting, the process doesn't get any signal when logging off from the shell where it was launched. This happens both when using the server's console and via SSH.

  • VirtualBox error with Ubuntu virtual machine

    - by user2985363
    I am trying to work on a coding project and cannot open my Ubuntu virtual machine with Oracle VM VirtualBox. I took a snapshot yesterday at about 11, and it was working fine. Several times I closed and reopened it. Today when I tried to open it, I kept getting the error below. Failed to open a session for the virtual machine Ubuntu 12.04 32-bit. VM cannot start because the saved state file 'C:\Users\Tyler\VirtualBox VMs\Ubuntu 12.04 32-bit\Snapshots\2014-01-30T19-59-05-976647800Z.sav' is invalid (VERR_FILE_NOT_FOUND). Deleted the saved state prior to starting the VM. I tried deleting the file as it said, but none of the snapshots would open still. The file is still in my recycling bin. What can I do? Also, I took the 1/31 snapshot today before I deleted the previous one.

  • Corosync - stopping the service crashes the server

    - by Antipop
    I am trying to set up a test cluster on a Xen Server with 2 paravirtualized CentOS 5.4 machines. I am using Pacemaker+Corosync, and following the instructions found at http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf and other sites. Anyway, when I try to manually stop the corosync service, about 80% of the times the whole VM locks up with the message "Waiting for corosync services to unload" and I am forced to shut the machine down manually. For the remaining 20%, the VM keeps responding and adds dots to the above message, but it won't actually stop the service. There aren't many resources on the internet about this particular error. Any ideas about this? Thanks in advance.
