  • Make cloudera-vm work on Oracle VM VirtualBox

    - by ????? ????????
    I downloaded this and the instructions say: Important: You must enable the I/O APIC in order to use 64-bit mode. (See http://www.virtualbox.org/manual/ch03.html.) On newer versions of VirtualBox, it may default to using SATA as the disk interface. This can cause a kernel panic in the VM. Switching to the IDE driver solves this problem. I am running this on Red Hat 64-bit mode (I've also tried on Ubuntu 64-bit with the same result). I pointed to the cloudera-vm image as a startup disk for the VM. I am getting this message: Failed to open a session for the virtual machine ClouderaDevelopment. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). Result Code: E_FAIL (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Does anyone know what I am doing wrong?

  • Memory cache Ubuntu 9.10 server x86 doesn't work as expected

    - by Matthijs
    We're using an Ubuntu 9.10 server to transfer Ghost-image files. We configured it only with Samba. And the DOS-clients connect to Samba. The latest updates are installed and so far the servers is running fine. When we image 10 pc's with the same image of 2 files of 2GB there's no disk activity. Everything is loaded in the RAM. There's 4GB in the server. But when we use 2 pc's with 2 different image files of 500 MB (8x) files then there's a lot of continuous disk activity. The speed is lower. So it seems that Ubuntu doesn't cache more then one big file. Are there settings to change this behaviour?

  • Using secure proxies with Google Chrome

    - by cYrus
    Whenever I use a secure proxy with Google Chrome I get ERR_PROXY_CERTIFICATE_INVALID, I tried a lot of different scenarios and versions. The certificate I'm using a self-signed certificate: openssl genrsa -out key.pem 1024 openssl req -new -key key.pem -out request.pem openssl x509 -req -days 30 -in request.pem -signkey key.pem -out certificate.pem Note: this certificate works (with a warning since it's self-signed) when I try to setup a simple HTTPS server. The proxy Then I start a secure proxy on localhost:8080. There are a several ways to accomplish this, I tried: a custom Node.js script; stunnel; node-spdyproxy (OK, this involves SPDY too, but later... the problem is the same); [...] The browser Then I run Google Chrome with: google-chrome --proxy-server=https://localhost:8080 http://superuser.com to load, say, http://superuser.com. The issue All I get is: Error 136 (net::ERR_PROXY_CERTIFICATE_INVALID): Unknown error. in the window, and something like: [13633:13639:1017/182333:ERROR:cert_verify_proc_nss.cc(790)] CERT_PKIXVerifyCert for localhost failed err=-8179 in the console. Note: this is not the big red warning that complains about insecure certificates. Now, I have to admit that I'm quite n00b for what concerns certificates and such, if I'm missing some fundamental points, please let me know.

  • Recover LVM2 volume group after one HDD failed

    - by Bernd
    I had two HDDs, each one containing a LVM partition which formed a volume group. Then I had two LVs, one for my / directory and one for my /home/ directory. Yesterday where I had my / dir failed. I'm trying to recover at least my /home/ dir. What I've done so far: Boot a live system Extract LVM2 metadata from the working HDD using dd Copy metadata to /etc/lvm/backup/vg0 Now I'm trying to do this: pvcreate --restore /etc/lvm/backup/vg0 --uuid "[uuid of my working hdd]" /dev/sdb2 But I always get: Couldn't find device with uuid '[uuid of broken hdd]'. Couldn't find device with uuid '[uuid of working hdd]'. Device /dev/sdb2 not found (or ignored by filtering). I confirmed that /dev/sdb2 exists and I've commented out all filtering settings from /etc/lvm/lvm.conf so I don't know what might be causing pvcreate not to find the device. So: What might be the problem? Is it even possible to restore this partition? (As I'm writing this I'm starting to think it's impossible D:) Edit: Okay, looks like I've got it figured out. I was using a Ubuntu 8.10 CD (yeah, I know it's not supported anymore) and it seems that was the problem. When I started from a Ubuntu 10.04 CD everything worked 'fine', I could mount my LVM partitions partially without problems. (Will answer the question in 4 hours. But if anyone has still got some hints/tips, please share! :)

  • gray dotted box outlining desktop icons on windows 7

    - by Max
    I occasionally get this problem where for some reason small, dotted gray boxes appear around my desktop icons. It always goes away after I restart, but I'm just curious what it is. I don't know of anything in particular I do to cause it, but it only outlines icons I click, and it only does it to one icon at a time. The picture below is the box on the recycle bin. IF I click a different icon it'll happen to that one instead. I'm using windows 7. Thank you.

  • Why should krfb use so much cpu when I never use it?

    - by Newton Falls
    I was playing around with KSysGuard and I noticed the process using the most cpu was krfb, which is the server process for desktop sharing. I never use desktop sharing so I suppose it is a default loaded process. Why would this process use so much juice (around 15%) when I never use it and it really shouldn't be doing much of anything? I don't see any network activity so I don't think I am being hacked. I have suspended the process and nothing bad seems to have happened. Can I assume this is a safe thing to do?

  • xinet vs iptables for port forwarding performance

    - by jamie.mccrindle
    I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

  • X11 tunnelling through SSH from Fedora 3 server to Windows Vista client fails to work.

    - by MiffTheFox
    Okay, I've tried using Xming and PuTTY, as well as Cygwin/X and Cygwin ssh, and it is not working. I've been able to run X applications locally, so it's not a client-side X problem. I've connected to the server using ssh -X user@server and ended up with this: local-user@client: ~$ ssh -X user@server user@server's password: Last login: Sun Jul 19 15:26:46 2009 from 192.168.100.147 [user@server ~]$ xclock & [1] 27770 [user@server ~]$ Error: Can't open display: localhost:10.0 [1]+ Exit 1 xclock [user@server ~]$ [user@server ~]$ Here's the relevant snippet of my sshd_config #AllowTcpForwarding yes #GatewayPorts no #X11Forwarding no X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes I can't seem to find ssh_config on the client-side. /etc/ssh doesn't exist.

  • Which server software and configuration to retrieve from multiple POP servers, routing by address to correct user

    - by rolinger
    I am setting up a small email server on a Debian machine, which needs to pick up mail from a variety of POP servers and figure out who to send it to from the address, but I'm not clear what software will do what I need, although it seems like a very simple question! For example, I have 2 users, Alice and Bob. Any email to [email protected] ([email protected] etc) should go to Alice, all other mail to domain.example.com should go to Bob. Any email to [email protected] should go to Bob, and [email protected] should go to Alice Anything to *@bobs.place.com should go to Bob And so on... The idea is to pull together a load of mail addresses that have built up over the years and present them all as a single mailbox for Bob and another one for Alice. I'm expecting something like Postfix + Dovecot + Amavis + Spamassassin + Squirrelmail to fit the bill, but I'm not sure where the above comes in, can Postfix deal with it as a set of defined regular expressions, or is it a job for Amavis, or something else entirely? Do I need fetchmail in this mix, or is its role now included in one of the other components above. I think of it as content-filtering, but everything I read about content-filtering is focussed on detecting spam rather than routing email.

  • 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.

  • View all users in a specific group in CentOS

    - by slayernoah
    I added a user user01 to a group group01 using: usermod -a -G group01 user01 When I run in command id user01 it shows that this user has actually been added to the group. However, the file /etc/group doesn't reflect this. i.e. I believe that on this file, users that belong to each of the groups should be listed next to it. Please correct me if I am wrong. This is a fresh installation of CentOS 6.4 Also, since id user01 shows that this is updated, is there any way to check all the members of group group01?

  • server will not reply (syn -ack)

    - by Brent
    I like to use the following commands to manage 'TIME_WAIT', in the hope to free up resources. echo 20 > /proc/sys/net/ipv4/tcp_fin_timeout sysctl -w net.ipv4.tcp_tw_reuse=1 sysctl -w net.ipv4.tcp_tw_recycle=1 I found something interesting while doing a tcpdump. Sometimes if a client makes a connection (syn), the server will not reply (syn -ack). My question is, could it be because of the top three commands.

  • What is the best MTA setup for a home/laptop computer (*not* server)?

    - by thomasrutter
    Hello, What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that is not always online? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they have a static IP have a domain name are always connected to the same network My requirements are, I guess: Ability to redirect mail for local users to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

  • Trouble installing SSL Certificate on Apache

    - by jahufar
    We have a dedicated server with GoDaddy running Plesk that requires SSL. I've generated the certificate files and I created a vhost_ssl.conf (since I can't edit the default plesk apache configuration http.include, vhost_ssl.conf gets Included to httpd.include) that tells apache where to find the certificate files: SSLCertificateFile /usr/local/psa/var/certificates/domain.com.crt SSLCertificateKeyFile /usr/local/psa/var/certificates/domain.com.key SSLCertificateChainFile /usr/local/psa/var/certificates/sub.class1.server.ca.pem When I stop/start apache, it refuses to start up. The error_log does not have anything on it either (which is strange). Then I opened up httpd.include and found this bit: <VirtualHost 208.xxx.xxx.xxx:443> ServerName domain.com:443 ServerAlias www.domain.com UseCanonicalName Off SSLEngine on SSLVerifyClient none SSLCertificateFile /usr/local/psa/var/certificates/certagC9054 Include /var/www/vhosts/domain.com/conf/vhost_ssl.conf Then I commented out SSLCertificateFile /usr/local/psa/var/certificates/certagC9054 (which is plesk's SSL certificate) and restarted apache and it worked perfectly fine. It seems that Apache does not like multiple SSLCertificateFile within the same VirtualHost directive? As anyone who worked with plesk knows, I can't just remove SSLCertificateFile directive in httpd.include as plesk will overwrite my changes when someone uses it - which is why it's in vhost_ssl.conf. So I'm stuck and this is beyond my meager admin skills. Would appreciate someone who knows what (s)he's doing to tell me whats going on. Thanks in advance.

    What do I need to add to my .emacs to get it to save all of my autosaves and backups into one directory? I don't do a lot of .emacs configuration, and I just can't get the variables out of emacsWiki to play right. Anybody mind sharing how they do it? I would prefer to have the saves placed in /tmp/emacs/{username}/{autosaves | backups} BONUS, configuration to do the same for TRAMP
