  • How Do I Install Latest Java Plugin on Ubuntu 8.04 LTS with Custom Firefox 3.6.3?

    - by Volomike
    I have Ubuntu 8.04 LTS and will need to remain on that for awhile as I am a programmer and cannot disturb what I'm doing in the middle of a project. As you know, it doesn't want to install the latest Firefox by default and keeps me in the stone age. So, I had to install my own Firefox. I did so and with relative ease I was able to install the Flash plugin using the normal 'ln -s' technique one usually does with /usr/lib/firefox/plugins. Now I need to do a Gotomypc.com task and it requires Java -- moan -- so I need to figure out how to install Java. I downloaded and installed the latest Java plugin in /usr/java, and I do see underneath that layer of folders a plugins folder with a .so file. So, I went to /usr/lib/firefox/plugins and did this: ln -s /usr/java/jre1.6.0_20/plugin/i386/ns7/libjavaplugin_oji.so Then, I also read on the web that one has to create a ~/.mozilla/plugins folder, cd into it, and then run the same ln -s command again. Another site recommended finding one's ~/.mozilla/firefox and renaming it to ~/.mozilla/firefox.old (after you backed up your bookmarks) and then launching firefox again so that it creates ~/.mozilla/firefox and uses the new Java plugin. Well, all these attempts have completely failed and it is incredibly frustrating. I do about:plugins to see my plugins and all I get are the Flash and the default null plugin. I do not see the Java one. Also, they said on my tools menu with Firefox 3.6.3 I would see a Java Console menu and I don't see that either. I found a pluginreg.dat somewhere deep under ~/.mozilla/firefox, but it does not list the Java plugin inside -- only Flash and the null plugin. Please help me install Java. I need to help a client out and need to connect to his PC remotely with gotomypc, which requires Java inside firefox.

  • Windows 7 x64 wired connection problem. IP, gateway, dns assigned, can't ping. Network detected as "Network"

    - by Emil Lerch
    I am having a problem connecting to a specific wired network with my Latitude E6410 laptop. Other wired networks seem to work fine, but this one does not. I have a coworker with me with the same Intel 82577LM Gigabit Network card, and he can connect just fine. I've updated to the latest Intel drivers (11.8.75.0) and am not using Pro Set. I obtain all DHCP information just fine (IP, netmask, DNS server, default gateway). I cannot ping anything (internal or on the Internet - I tried pinging Google's public DNS servers by IP 8.8.8.8), nor can I get answers to any DNS queries through NS Lookup. Windows troubleshooting says everything is fine, but I can't get DNS responses. I've seen issues like this in the past that were related to link speed/duplex autonegotiaion failures, so I've tried manually setting link speed/duplex to all values one by one with no success. My coworker is using all default settings, so he is just using autonegotiate. Any ideas of other things to try?

  • really weird DNS problem in Ubuntu {after one month, seems like ISP problem}

    - by OmniWired
    Hello everyone. I been having this random dns problem, in Ubuntu 10.04 and in 10.10 it started about 2 weeks ago after (I believe) an update. Basically when I go to a website randomly I get that the website I'm visiting is not available ("Oops! Google Chrome could not connect to ..." & "This webpage is not available."). I tested with Chromium "7.0.515.0 (58587)" and Firefox minefield (4.0ish) and 3.6.9. I did these 4 things already: /etc/default/grub GRUB_CMDLINE_LINUX="ipv6.disable=1" and this: /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 *disabling Chromium DNS pre-fetching *using Google and OpenDNS servers as well as ISP DNS servers. But didn't improve, also no other computers in my network have the same problem. All computer wired to the same router. I'm a software engineer that run out of ideas, please help me. Thanks in advance. UPDATE: some programs (synaptic / firefox update/ vuze(azureus)) say connection refused for the error. Most of the time a second try will fix the "refusal". UPDATE2: I found out with Wireshark, that everytime I have this problem i've got this 192.168.0.10 8.8.8.8 ICMP Destination unreachable (Port unreachable) Confirmed an ISP error. ISP;Speedy Location: Argentina, Buenos Aires (capital Federal) Area.

  • Abysmal transfer speeds on gigabit network

    - by Vegard Larsen
    I am having trouble getting my Gigabit network to work properly between my desktop computer and my Windows Home Server. When copying files to my server (connected through my switch), I am seeing file transfer speeds of below 10MB/s, sometimes even below 1MB/s. The machine configurations are: Desktop Intel Core 2 Quad Q6600 Windows 7 Ultimate x64 2x WD Green 1TB drives in striped RAID 4GB RAM AB9 QuadGT motherboard Realtek RTL8810SC network adapter Windows Home Server AMD Athlon 64 X2 4GB RAM 6x WD Green 1,5TB drives in storage pool Gigabyte GA-MA78GM-S2H motherboard Realtek 8111C network adapter Switch dLink Green DGS-1008D 8-port Both machines report being connected at 1Gbps. The switch lights up with green lights for those two ports, indicating 1Gbps. When connecting the machines through the switch, I am seeing insanely low speeds from WHS to the desktop measured with iperf: 10Kbits/sec (WHS is running iperf -c, desktop is iperf -s). Using iperf the other way (WHS is iperf -s, desktop iperf -c) speeds are also bad (~20Mbits/sec). Connecting the machines directly with a patch cable, I see much higher speeds when connecting from desktop to WHS (~300 Mbits/sec), but still around 10Kbits/sec when connecting from WHS to the desktop. File transfer speeds are also much quicker (both directions). Log from desktop for iperf connection from WHS (through switch): C:\temp>iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [248] local 192.168.1.32 port 5001 connected with 192.168.1.20 port 3227 [ ID] Interval Transfer Bandwidth [248] 0.0-18.5 sec 24.0 KBytes 10.6 Kbits/sec Log from desktop for iperf connection to WHS (through switch): C:\temp>iperf -c 192.168.1.20 ------------------------------------------------------------ Client connecting to 192.168.1.20, TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [148] local 192.168.1.32 port 57012 connected with 192.168.1.20 port 5001 [ ID] Interval Transfer Bandwidth [148] 0.0-10.3 sec 28.5 MBytes 23.3 Mbits/sec What is going on here? Unfortunately I don't have any other gigabit-capable devices to try with.

  • RabbitMQ - How I do configure servers for zero-downtime upgrades?

    - by Terence Johnson
    Having read through the docs and RabbitMQ in Action, creating a RabbitMQ cluster seems straightforward enough, but upgrading or patching an existing RabbitMQ cluster seems to require the whole cluster to be restarted. Is there a way to combine clustering, shovel, federation, and load balancing to make a rolling upgrade possible without losing queues or messages, or have I missed something slightly more obvious?

  • nginx: SSI working on Apache backend, but not on gunicorn backend

    - by j0nes
    I have nginx in front of an Apache server and a gunicorn server for different parts of my website. I am using the SSI module in nginx to display a snippet in every page. The websites include a snippet in this form: For static pages served by nginx everything is working fine, the same goes for the Apache-generated pages - the SSI include is evaluated and the snippet is filled. However for requests to my gunicorn backend running a Python app in Django, the SSI include does not get evaluated. Here is the relevant part of the nginx config: location /cgi-bin/script.pl { ssi on; proxy_pass http://default_backend/cgi-bin/script.pl; include sites-available/aspects/proxy-default.conf; } location /directory/ { ssi on; limit_req zone=directory nodelay burst=3; proxy_pass http://django_backend/directory/; include sites-available/aspects/proxy-default.conf; } Backends: upstream django_backend { server dynamic.mydomain.com:8000 max_fails=5 fail_timeout=10s; } upstream default_backend { server dynamic.mydomain.com:80; server dynamic2.mydomain.com:80; } proxy_default.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; What is the cause for this behaviour? How can I get SSI includes working for my pages generated on gunicorn? How can I debug this further?

  • Delay after commit before Redmine comments ticket

    - by Paul
    I was used to having a post-commit hook trigger processing of the commit message by Trac (SVN repository). The comment (or action) was added immediately. Now I switched to Mercurial as a VCS and Redmine as a ticketing system. Redmine does recognize information in changeset/commit messages like "refs #185" - but it takes several minutes to appear in the ticket. Any ideas why this is? Is the routine to grab the changesets called periodically somehow?

  • How to sync two computers using new MobileMe calendar

    - by CesarGon
    I have been using MobileMe for over a year with success. I use it to sync my Outlook calendars in my work and home computers, using Windows 7 and Outlook 2007. The main Outlook calendar folder in my work computer is replicated to MobileMe as "Work", and synced to my home computer, and the main calendar folder in my home computer is replicated to MobileMe as "Home", and synced to my work computer. This means that I can see both "Work" and "Home" calendars from both computers (as well as from the web interface through me.com), which is very convenient. Yesterday I migrated to the new MobileMe calendar, accepting the suggestion that popped up on the me.com website. After the migration, the MobileMe control panel on each of Windows computers asked me to re-configure my calendar setup, and everything fell apart. The "Home" and "Work" calendar folders in Outlook are now ignored by MobileMe, and new ones named "Home in MobileMe" and "Work in MobileMe" have been created, and placed in a separate Outlook data file rather than the default. This means that now: I now have four folders, two of which are not replicated to MobileMe The two folders that are not replicated reside on a separate data file, so alarms and reminders don't work; they're basically useless to me as calendar folders In addition, the button in the MobileMe Control Panel that used to let me specify what MobileMe folder should be synced against the default Outlook folder has gone. MobileMe is now too smart. Do you have any idea how to undo this mess and go back to a situation where I have two folders, as described in the top paragraph, which keep synced? I don't want an extra data file. Thanks.

  • FTP Server on Centos 5.8 - Transfer fails randomly

    - by Diego
    Hi have ProFTPD runningon a brand new CentOS 5.8 server with Plesk, and its behaviour is inconsistent at best. I tried to transfer a directory from my PC, and every time I get a transfer failed on a random file. It's never the same one that fails, it just fails. Sometimes it's a .gif, sometimes it's a .css, sometimes it's a JPG. Of several hundred files, a dozen is always failing for no apparent reason. The error that I get is the following: COMMAND:> [27/11/2012 11:43:52] STOR main_border.gif [27/11/2012 11:43:53] 500 Invalid command: try being more creative ERROR:> [27/11/2012 11:43:53] Syntax error: command unrecognized. The above is just an example, the "command unrecognized" occurs with LIST and other commands as well. Here's the ProFTPD configuration, just in case: ServerName "ProFTPD" #ServerType standalone ServerType inetd DefaultServer on <Global> DefaultRoot ~ psacln AllowOverwrite on </Global> DefaultTransferMode binary UseFtpUsers on TimesGMT off SetEnv TZ :/etc/localtime Port 21 Umask 022 MaxInstances 30 ScoreboardFile /var/run/proftpd/scoreboard TransferLog /usr/local/psa/var/log/xferlog #Change default group for new files and directories in vhosts dir to psacln <Directory /var/www/vhosts> GroupOwner psacln </Directory> # Enable PAM authentication AuthPAM on AuthPAMConfig proftpd IdentLookups off UseReverseDNS off AuthGroupFile /etc/group Include /etc/proftpd.include Note: file /etc/proftpd.include is blank. The above is the default configuration set by Plesk 11. I don't know much of why is that way, my knowledge of Linux System Administration is very basic and the one of ProFTPD is a complete zero. Thanks in advance for the help. Update Issue experienced with CuteFTP and FileZilla. Update Replaced ProFTPd with PureFTPd, issue persists. Sometimes I get "command unrecognized", sometimes "failed to establish data connection". I'm starting to think that it could be a network issue, but I have completely zero knowledge of networking.

  • IIS 7 + Tomcat 7 - how to reach http://localhost:8080/my_app under e.g. http://my_app.local

    - by Sk8erPeter
    In brief: IIS 7 + Apache Tomcat 7 + isapi_redirect.dll: I have a deployed and working Tomcat-application available under http://localhost:8080/my_app. I would like to see the same content under http://my_app.local (and NOT the default Tomcat-site [which you can see below]). How can I do that? Longer explained: I have IIS 7 (7.5.7600.16385) and Apache Tomcat/7.0.22 installed. I deployed an application (let's call it "my_app") in Tomcat, which now can be reached at http://localhost:8080/my_app, works fine. I added a new web site in IIS panel with the path of the Tomcat deployed my_app, which looks like this: "c:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\my_app" I binded the host name my_app.local. After that, I configured isapi_redirect.dll like this (or that). Now, when I open http://my_app.local, I can see the default Tomcat site (see below). BUT under http://my_app.local I would like to see the same content as under http://localhost:8080/my_app. How can I do that? Thank you very much in advance!! my config files: isapi_redirect.properties (I made a dir junction to c:\tomcat, so this also works :) ) workers.properties uriworkermap.properties rewrites.properties (empty)

  • VMware or Xen support for AIX on pSeries architecture

    - by A.Rashad
    I tried to find an explicit confirmation on VMware website if there is any chance we could virtualize AIX running on pSeriese architecture (P5, P6 and P7), but in vain. so far we have only one product available which is PowerVM (IBM Product) but we are trying to find alternative solutions to evaluate pros and cons before taking any action. Even Xen mentions the support for Power PC but for Linux not AIX. I hope someone could give an insight on this matter.

  • Multicast hostname lookups on OSX

    - by KARASZI István
    I have a problem with hostname lookups on my OSX computer. According to Apple's HK3473 document it says for v10.6: Host names that contain only one label in addition to local, for example "My-Computer.local", are resolved using Multicast DNS (Bonjour) by default. Host names that contain two or more labels in addition to local, for example "server.domain.local", are resolved using a DNS server by default. Which is not true as my testing. If I try to open a connection on my local computer to a remote port: telnet example.domain.local 22 then it will lookup the IP address with multicast DNS next to the A and AAAA lookups. This causes a two seconds lookup timeout on every lookup. Which is a lot! When I try with IPv4 only then it won't use the multicast queries to fetch the remote address just the simple A queries. telnet -4 example.domain.local 22 When I try with IPv6 only: telnet -6 example.domain.local 22 then it will lookup with multicast DNS and AAAA again, and the 2 seconds timeout delay occurs again. I've tried to create a resolver entry to my /etc/resolver/domain.local, and /etc/resolver/local.1, but none of them was working. Is there any way to disable this multicast lookups for the "two or more label addition to local" domains, or simply disable it for the selected subdomain (domain.local)? Thank you!

  • Windows Vista: Folder options not working

    - by Thomas Matthews
    I'm running Windows Vista Service Pack 2. I have the Folder Options set to "Open each folder in the same window." (Organize | Folder Options | General). Each time I open a folder, it opens in a new window. How do I get it to open each folder in the same window? I have tried the following techniques with no success: 1. Expand number of MBAG entries in Registry. (The number is 40,000 now.) 2. Delete Bags and MBAG entries in Registry. (Rebooted machine after, still no success). 3. Change to "Open each folder in its own window". Saved, then changed back. 4. Under View tab, changed "Remember each folder's view settings": unchecked, Apply to Folders, checked, Apply to folders. 5. Applied application from Annoyances.org. Still no success. 6. Clicked on Reset Default Options, then OK. (Opening in same fold is a default option!) Still unsucessful. I want the folders to open in the same window, just like the options say.

    So if i do eject on my machine, it works exactly as expected, however, if i ssh into the machine next to me, and do the same thing, it does not work... my computer: eject: using default device `cdrom' eject: device name is `cdrom' eject: expanded name is `/dev/cdrom' eject: `/dev/cdrom' is a link to `/dev/sr0' eject: `/dev/sr0' is not mounted eject: `/dev/sr0' is not a mount point eject: checking if device "/dev/sr0" has a removable or hotpluggable flag eject: `/dev/sr0' is not a multipartition device eject: trying to eject `/dev/sr0' using CD-ROM eject command eject: CD-ROM eject command succeeded other computer: eject: using default device `cdrom' eject: device name is `cdrom' eject: expanded name is `/dev/cdrom' eject: `/dev/cdrom' is a link to `/dev/sr0' eject: `/dev/sr0' is not mounted eject: `/dev/sr0' is not a mount point eject: checking if device "/dev/sr0" has a removable or hotpluggable flag eject: `/dev/sr0' is not a multipartition device eject: unable to open `/dev/sr0' if i look in the /dev/ dir, then i find cdrom which is a symlink to sr0 - as mentioned by the verbose outputs of eject -v. On my machine, if i try and look at it, if the drive is open, it will close it, and then give this: $ less sr0 sr0 is not a regular file (use -f to see it) so $ less -f sr0 sr0: No medium found but if i do it on the other computer, $ less -f sr0 sr0: Permission denied so i look at the files more, and get this on both machines: $ ls -la sr0 brw-rw----+ 1 root cdrom 11, 0 Nov 12 10:13 sr0 Does anyone know a way around this? I do not have root access.

  • IPv6 Routing / Subnetting

    - by nappo
    Recently I have installed Citrix Xen Server 6.2 on a machine. My Provider (Hetzner) gave me the IPv6 Subnet 2a01:4f8:200:xxxx::/64. Followed an article in the providers wiki (1) i got it working and can assign IPs to my guests (CentOS). However i can't assign a second IP to a single guest - it will result in a timeout. I'm not very familiar with IPv6 routing / subnetting - any help or tips for further troubleshooting is welcome! My Setup: XenServer 6.2 IPv6: 2a01:4f8:200:xxxx::2/112 ip -6 route: 2a01:4f8:200:xxxx::/112 dev xenbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 default via fe80::1 dev xenbr0 metric 1024 mtu 1500 advmss 1440 hoplimit 0 Guest 1 IPv6: 2a01:4f8:200:xxxx::3/64 IPv6: 2a01:4f8:200:xxxx::4/64 ip -6 route: 2a01:4f8:200:xxxx::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::1 dev eth0 metric 1 mtu 1500 advmss 1440 hoplimit 4294967295 Guest 2 IPv6: 2a01:4f8:200:xxxx::5/64 Guest 1 IPv6 is working fine, Guest 2 too. As suggested by the wiki article (1) i split my /64 network into a /112. Is it right to set the host /112 and the guests /64? Why is that?

  • Desktop bigger than screen

    - by alex
    I am using MSI U115 11" netbook (OS: Windows XP Home, graphics card: Intel Graphics Media Accelerator 500) and today after I switched it on, desktop was bigger than screen. To be exact: screen resolution was set to the lowest possible and I could move mouse outside of screen (but only below - left, right and up worked normally, mouse could not exceed screen boundaries). I changed resolution back to normal, but the problem with desktop being bigger than screen remained (as before, only lower part - cannot see task bar, etc. When I hit windows button on keyboard, only upper part of menu start is visible). What I already tried was changing all kind of graphics and screen settings - none of them helped. I also tried to restore the system to few days before, but it didn't help neither. What can I do to make the desktop look "normally"? EDIT: Some additional info regarding screen: Sorry it's in polish - but let me explain. There are two screens I can choose (Monitor domyslny means default screen), but the second one (the default one) is not available. After I choose it and click apply number 1. is used (and as you can see it has only two resolutions available. There are more in the second one - but without 1024x600 though). The two ticked and grayed out options here are Use this screen as the main one and Enlarge Windows desktop to match this monitor's size. Too bad I cannot change them. When I choose the second screen, the first box is unchecked and grayed out. The second box is available to be changed but it doesn't matter anyway as after applying changes it reverts to the first screen anyway. EDIT: Intel Graphics Media Control Panel screenshot.

  • Xen PV packet loss

    - by Delphinator
    I'm having some serious issues with packetloss with one of my servers. This server is a somewhat old (P4-era) machine running Debian Squeeze and Xen 4.0. There are two domUs running on it (both also Debian Squeeze), one gateway and a fileserver. Unfortunatly the processor has no virtualization extensions, therefore only PV can be used. While investigating why our network seems to be slower than it should I found some pretty bad packet loss (~25%). After further investigation and several experiments I did a measurment between the dom0 and one of the domUs: Server listening on UDP port 5001 Receiving 1470 byte datagrams UDP buffer size: 110 KByte (default) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to dom0, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 110 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.1.2(domU) port 33817 connected with 192.168.1.100(dom0) port 5001 [ 4] local 192.168.1.2(domU) port 5001 connected with 192.168.1.100(dom0) port 48606 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 46.3 MBytes 38.7 Mbits/sec [ 3] Sent 33020 datagrams [ 3] Server Report: [ 3] 0.0-10.0 sec 46.2 MBytes 38.6 Mbits/sec 0.030 ms 89/33019 (0.27%) [ 3] 0.0-10.0 sec 1 datagrams received out-of-order [ 4] 0.0-10.2 sec 43.0 MBytes 35.3 Mbits/sec 13.074 ms 11575/42256 (27%) tl;dr: 27% packet loss from dom0 to domU with 50Mbit UDP packets. Same thing happens from anywhere in the network. The problem gets better for smaller bandwidths (0.047% for 5Mbit) and worse for higher (59% for 200Mbit) ones. I did increase the CPU-weight of the dom0, there is no swapping going on, and actual networking-hardware is not involved. I never expected Xen (or anything related) to drop packets, and I'm completly clueless what to try next.

  • Cisco ASA Site-to-Site VPN Dropping

    - by ScottAdair
    I have three sites, Toronto (1.1.1.1), Mississauga (2.2.2.2) and San Francisco (3.3.3.3). All three sites have ASA 5520. All the sites are connected together with two site-to-site VPN links between each other location. My issue is that the tunnel between Toronto and San Francisco is very unstable, dropping every 40 min to 60 mins. The tunnel between Toronto and Mississauga (which is configured in the same manner) is fine with no drops. I also noticed that my pings with drop but the ASA thinks that the tunnel is still up and running. Here is the configuration of the tunnel.

  • 403 Forbidden error on Mac OSX - Apache and nginx

    - by tlianza
    Hi All, There are a million questions like this on Google, but I haven't found a solution to my problem. The default Apache install on my Mac is giving 403 Forbidden errors for everything (default directory, user home directory, virtual server, etc). After sifting through the config files, I figured I'd give nginx a try. Nginx serves files fine from it's home directory, but it won't serve files from a subfolder of my user directory. I've configured a simple virtual host, and requesting index.html returns a 403-forbidden. The error message in nginx's log file is pretty clear - it can't read the file: 2011/01/04 16:13:54 [error] 96440#0: *11 open() "/Users/me/Documents/workspace/mobile/index.html" failed (13: Permission denied), client: 127.0.0.1, server: local.test.com, request: "GET /index.html HTTP/1.1", host: "local.test.com" I've opened up this directory to everyone: drwxrwxrwx 6 me admin 204B Dec 31 20:49 mobile And all the files in it: $ ls -lah mobile/ total 24 drwxrwxrwx 6 me admin 204B Dec 31 20:49 . drwxr-xr-x 71 me me 2.4K Dec 31 20:41 .. -rw-r--r--@ 1 me me 6.0K Jan 2 18:58 .DS_Store -rwxrwxrwx 1 me admin 2.1K Jan 4 14:22 index.html drwxrwxrwx 5 me admin 170B Dec 31 20:45 nbproject drwxrwxrwx 5 me admin 170B Jan 2 18:58 script And yet, I cannot figure out why the nginx process cannot read index.html. It's running as the "nobody" user, but the permissions are set such that anyone can read them.

  • Mindtouch broke my Apache2 virtual host configuration.

    - by grenade
    I installed mindtouch using the instructions here and it seems to have broken my Virtual Host configuration. I have several domains running off the same apache instance and this was working fine but now all my domain names resolve to the virtualhost where mindtouch was installed. So mindtouch made all my domain names point to the new mindtouch instance. Grrr! I use debians default virtual host mechanisms (sites-enabled, etc). Does anyone know what apache directive mindtouch is using to ruin my vh setup? I've scoured all the conf files and there is nothing obvious in apache2.conf or httpd.conf that would cause the behaviour. Did it create a sym-link somewhere that I should destroy? I should add that I uninstalled the mindtouch packages already but apache persists in redirecting all domains to the first one mentioned in the sites-enabled folder. thini:~# apache2ctl -S [Wed Jan 05 13:39:11 2011] [warn] NameVirtualHost *:80 has no VirtualHosts VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:* www.openancestry.org (/etc/apache2/sites-enabled/openancestry.org:1) *:* www.pragmantra.com (/etc/apache2/sites-enabled/pragmantra.com:1) *:* services.pragmantra.com (/etc/apache2/sites-enabled/services.pragmantra.com:1) *:* www.subversionreports.com (/etc/apache2/sites-enabled/subversionreports.com:1) *:* www.thijssen.ch (/etc/apache2/sites-enabled/thijssen.ch:1) Syntax OK

  • CentOS iscsi initiator has session but there is no block device

    - by jcalfee314
    I have installed the scsi-target-utils package on CentOS and I used it to perform a discovery. The discovery did give me an active session. I restarted the iscsi service but I do not see any new devices (fdisk -l). I see in /var/log/messages that my connection is operational now. I'm not sure how to debug this further. Can someone direct me into fixing this? discovery: iscsiadm -m discovery -t sendtargets -p 192.168.0.155 returns: 192.168.0.155:3260,-1 iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3 Just to verify it actually worked: iscsiadm -m session returns tcp: [1] 192.168.0.155:3260,1 iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3 restarting as the directions say to do: service iscsi restart output written to /var/log/message Stopping iscsi: Sep 20 12:14:22 localhost kernel: connection1:0: detected conn error (1020) [ OK ] Starting iscsi: Sep 20 12:14:22 localhost kernel: scsi1 : iSCSI Initiator over TCP/IP Sep 20 12:14:22 localhost iscsid: Connection1:0 to [target: iqn.2009-02.com.twinstrata:cloudarray:sn-1d07c1b62d4ec8f3, portal: 192.168.0.155,3260] through [iface: default] is shutdown.

Next I compared the output from "fdisk -l|egrep dev" both with the iscsi session and without. There is no difference. I suppose I could just look in /etc/mtab. Any ideas on how I can get an iscsi device?
