  • Can't copy and paste to Netbeans when accessed over RDC

    - by Freiheit
    I use Netbeans for development and I access it by using a Windows Remote Desktop Connection back to my workstation at HQ. This is a great set up except for one thing, I cannot copy text on my local machine and paste it into Netbeans. I can copy and paste into other applications. Any ideas as to the cause? How can I fix it?

  • Small business: what should I know about computer security?

    - by geschema
    I run a small (1 man) consulting company in the field of embedded systems, working from home using a standard DSL internet access. My main development machine is a Windows XP PC, which is connected to the router with an ethernet cable. I also have a MacBook Pro laptop, which is connects to the network via WLAN (WPA-PSK). Besides enabling the Windows firewall, not using IE, having an up-to-date antivirus program and strong passwords, what do I need to know to keep my customers' data safe on these computers?

  • Why does writing a file to an NFS share send a COMMIT operation to the NFS server?

    - by Antonis Christofides
    I have a Debian squeeze (2.6.32-5-amd64) which is at the same time a NFS4 server and client (it mounts itself through NFS4). The local directory that leads directly to disk is /nfs4exports/mydir, whereas /nfs4mounts/mydir is the same thing mounted through NFS, using the machine's external IP address. Here is the line from fstab: 192.168.1.75:/mydir /nfs4mounts/mydir nfs4 soft 0 0 I have an application that writes many small files. If I write directly to /nfs4exports/mydir, it writes thousands of files per second; but if I write to /nfs4mounts/mydir, it writes 4 files per second or so. I can greatly increase speed if I add async to /etc/exports. (Writing a single large file to the NFS-mounted directory goes at more than 100 MB/s.) I examine the server statistics and I see that whenever a file is written, it is "committed" (this also happens with NFSv3): root@debianvboxtest:~# mount -t nfs4 192.168.1.75:/mydir /mnt root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 10 4% 1 0% 1 0% root@debianvboxtest:~# echo 'hello' >/mnt/test1056 root@debianvboxtest:~# nfsstat|grep -A 2 'nfs v4 operations' Server nfs v4 operations: op0-unused op1-unused op2-future access close commit 0 0% 0 0% 0 0% 11 4% 2 0% 2 0% Now in the RFC, I read this: The COMMIT operation is similar in operation and semantics to the POSIX fsync(2) system call that synchronizes a file's state with the disk (file data and metadata is flushed to disk or stable storage). COMMIT performs the same operation for a client, flushing any unsynchronized data and metadata on the server to the server's disk or stable storage for the specified file. I don't understand why the client commits. I don't think that the "echo" shell built-in command runs fsync; if echo wrote to a local file and then the machine went down, the file might be lost. In contrast, the NFS client appears to be sending a COMMIT upon completion of the echo. Why? I am reluctant to use the async NFS server option, because it would apparently ignore COMMIT. I feel as if I had a local filesystem and I had to choose between syncing every file upon close and ignoring fsync altogether. What have I understood wrong?

  • Internet Explorer cannot display page from apache with single SSL virtual host

    - by P.scheit
    I have a question that has come up somehow in different questions but I still can't find the solution, yet. My problem is that I'm hosting a site on apache 2.4 on debian with SSL and Internet Explorer 7 on windows xp shows Internet Explorer cannot display the webpage I have only ONE virtual host that uses ssl, but DIFFERENT virtual hosts that use http. Here is my config for the site with SSL enabled (etc/sites-avaible/default-ssl is NOT linked) <Virtualhost xx.yyy.86.193:443> ServerName www.my-certified-domain.de ServerAlias my-certified-domain.de DocumentRoot "/var/local/www/my-certified-domain.de/current/www" Alias /files "/var/local/www/my-certified-domain.de/current/files" CustomLog /var/log/apache2/access.my-certified-domain.de.log combined <Directory "/var/local/www/my-certified-domain.de/current/www"> AllowOverride All </Directory> SSLEngine on SSLCertificateFile /etc/ssl/certs/www.my-certified-domain.de.crt SSLCertificateKeyFile /etc/ssl/private/www.my-certified-domain.de.key SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM SSLCertificateChainFile /etc/apache2/ssl.crt/www.my-certified-domain.de.ca BrowserMatch "MSIE [2-8]" nokeepalive downgrade-1.0 force-response-1.0 </VirtualHost> <VirtualHost *:80> ServerName www.my-certified-domain.de ServerAlias my-certified-domain.de CustomLog /var/log/apache2/access.my-certified-domain.de.log combined Redirect permanent / https://www.my-certified-domain.de/ </VirtualHost> my ports.conf looks like this: NameVirtualHost *:80 Listen 80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP. Listen 443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> the output from apache2ctl -S is like this: xx.yyy.86.193:443 www.my-certified-domain.de (/etc/apache2/sites-enabled/020-my-certified-domain.de:1) wildcard NameVirtualHosts and _default_ servers: *:80 is a NameVirtualHost default server phpmyadmin.my-certified-domain.de (/etc/apache2/conf.d/phpmyadmin.conf:3) port 80 namevhost phpmyadmin.my-certified-domain.de (/etc/apache2/conf.d/phpmyadmin.conf:3) port 80 namevhost staging.my-certified-domain.de (/etc/apache2/sites-enabled/010-staging.my-certified-domain.de:1) port 80 namevhost testing.my-certified-domain.de (/etc/apache2/sites-enabled/015-testing.my-certified-domain.de:1) port 80 namevhost www.my-certified-domain.de (/etc/apache2/sites-enabled/020-my-certified-domain.de:31) I included the solution for this question: Internet explorer cannot display the page, other browsers can, possibly htaccess / server error And I understand the answer from this question: How to setup Apache NameVirtualHost on SSL? In fakt: I only have one ssl certificate for the domain. And I only want to run ONE virtual host with ssl. So I just want to use the one ip for the ssl virtual host. But still (after rebooting / restarting / testing) internet explorer will still not show the page. When I intepret the apachectl -S as well, I already have only one SSL host and this should response to the initial SSH handshake, shouldn't it? What is wrong in this setup? Thank you so much Philipp

  • Problems set-up Single Sign-On using Kerberos authentication

    - by user1124133
    I need for Ruby on Rail application set authentication via Active Directory using Kerberos authentication. Some technical information: I are using Apache installed mod_auth_kerb In httpd.conf I added LoadModule auth_kerb_module modules/mod_auth_kerb.so In /etc/krb5.conf I added following configuration [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = EU.ORG.COM dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h forwardable = yes [realms] EU.ORG.COM = { kdc = eudc05.eu.org.com:88 admin_server = eudc05.eu.org.com:749 default_domain = eu.org.com } [domain_realm] .eu.org.com = EU.ORG.COM eu.org.com = EU.ORG.COM [appdefaults] pam = { debug = true ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false } When I test kinit validuser and enter password then authentication is successful. klist returns: Ticket cache: FILE:/tmp/krb5cc_600 Default principal: [email protected] Valid starting Expires Service principal 02/08/13 13:46:40 02/08/13 23:46:47 krbtgt/[email protected] renew until 02/09/13 13:46:40 Kerberos 4 ticket cache: /tmp/tkt600 klist: You have no tickets cached In application Apache configuration I added IfModule mod_auth_kerb.c> Location /winlogin> AuthType Kerberos AuthName "Kerberos Loginsss" KrbMethodNegotiate off KrbAuthoritative on KrbVerifyKDC off KrbAuthRealms EU.ORG.COM Krb5Keytab /home/crmdata/httpd/apache.keytab KrbSaveCredentials off Require valid-user </Location> </IfModule> I restarted apache Now some tests: When I try to access application from Win7, I got pop-up message box, with text: Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentification without a secure connection) When I enter valid credentials then my application opens successfully, and all works fine. Questions: Is ok that for user pop-ups such windows? If I use NTLM authentication then there no such pop-up. I checked IE Internet Options and there 'Enable Integrated Windows Authentication' is checked. Why IE try to send username and password to application apache? If I correct to understand then Windows self must make authentication via Active Directory using Kerberos protocol. When I try to access application from Win7 and I enter incorrect credentials to pop-up message box Application say Authentication failed (this is OK) In apache error log I see: [error] [client 192.168.56.1] krb5_get_init_creds_password() failed: Client not found in Kerberos database But now I cannot get possibility to enter valid credentials, only when I restart IE I can get again pop-up box. What could be incorrect or missing in my Kerberos setup? I read in some blog post that probably something is needed to be done in Active Directory side. What exactly?

    - by Unreason
    Looking for a way to disable a feature in CKEditor that messes with attributes height and width on my and converts them into inline styles. The version of CKEditor is 3.2 and I have access to config files. Along the same lines is there somewhere an overview (or procedure) for changing the way CKEditor produces html (I'd like to force it to do inline styles; except for images, plus some other changes) Thank you for taking the time to read this

  • Server unable to communicate OUT, fine serving traffic

    - by jonoabroad
    We have several servers that are randomly loses the ability to communicate out to other nodes on the local network and internet. However websites are being served fine and we still have ssh access. A reboot seems to fix the problem for a few days. The servers are running 10.5.X and are fully up to date with software updates. Does anyone have any opinions, we think it is probably an ISP router, but we are guessing. Cheers Jono

  • Decrypting and reading a FileVault sparsebundle in Linux?

    - by Eemeli Kantola
    Hi, My MacBook's HD started failing recently. Fortunately most of the data was properly backed up and most of the other important data could be retrieved by hooking up the drive with the help of an external USB enclosure, but the problem is that my home directory has been encrypted with FileVault and I currently don't have easy access to a Mac. So can the FileVault sparsebundle be somehow decrypted and read with Linux?

  • How to change a physical partition system to LVM?

    - by Daniel Hernández
    I have a server with Debian that have 3 physical partitions covering all the disk: boot, root y swap. Now I want to replace that partitions with LVM partitions. I know how install Debian with LVM at beginning, but in this case I can't install the system at beginning because the provider gets me a server with remote access and the system installed in this way. How can I change that partitions using only an ssh connection and possibly other remote server where to put some temporal data?

  • Disk usage treemap software for headless Linux

    - by CyberShadow
    There are some programs which can display used disk space using a treemap, such as WinDirStat for Windows and KDirStat for KDE/Linux: I'm looking for something similar, but for a headless Linux box. (E.g. run console data collection program on the server, then load the file in a graphical program in a GUI environment.) Alternatively, what are other good ways to get a structured used disk space representation, with just SSH access?

  • What is the best way to remove duplicate files on web hosting's FTP server?

    - by Eric Harrison
    For some reason(Happened before I started working on this project)- my client's website has 2 duplicates of every single file. Effectively tripling the size of the site. The files look much like this: wp-comments-post.php | 3,982 bytes wp-comments-post (john smith's conflicted copy 2012-01-12).php | 3,982 bytes wp-comments-post (JohnSmith's conflicted copy 2012-01-14).php | 3,982 bytes The hosting that the website is on has no access to bash or SSH. In your opinion, what would be the easiest way to delete these duplicate files that would take the least time?

  • Virsh: Different XML with edit than dumpxml. Why?

    - by Dave Vogt
    I'm trying to fetch the VNC access data from a virtual machine managed by libVirt. However, when I run virsh dumpxml $machine, the vnc passwd is missing: <graphics type='vnc' port='-1' autoport='yes'/> Checking the same using virsh edit $machine, I see the password is actually there: <graphics type='vnc' port='-1' autoport='yes' passwd='asdf'/> Why is this? Is this intentional (what reason?), or could this be a bug?

  • Drupal on an NFS share has terrible performance

    - by Marcus
    We have a setup where a Drupal 7 site with the following setup - a VMware ESXi 4.1 host server running a web vm and an NFS VM. The web VM is using Apache and mod_php. The site is still in development thus we have to turn off all forms of caching due to the frequently-updated files. Each page request takes around 15-20 seconds to complete. Profiling the PHP code shows that the vast majority of time (normally over 90%) is taking by all the is_dir(), is_file() function calls that load up the modules. I've increased PHP's realpath cache size to several megs and an strace shows that the lstat calls then drop from over 200 to around 6 and stat() decreases a bit (around 600 calls). However, while this has shaved off quite a bit of time, I am simply unable to break past the 10 second per request barrier. Is there a way to get better performance out of this setup that doesn't involve caching? Configs and stats: VMs: web - Centos 6 64bt, 2.5GB RAM, normal CPU/HD prioritisation nfs - Centos 6 64bt, 2GB RAM, normal CPU priority, high HD priority PHP: 32M realpath cache size (it's this high for testing purposes) NFS: ~]# egrep -v '#|^$' /etc/nfsmount.conf [ NFSMount_Global_Options ] Defaultvers=4 Ac=False Rsize=32k Wsize=32k Bsize=32k Reading speeds via NFS are not an issue a dd of a 100M test file using 32k blocks returns: 3200+0 records in 3200+0 records out 104857600 bytes (105 MB) copied, 1.84984 s, 56.7 MB/s real 0m1.857s user 0m0.007s sys 0m0.330s Strace on Apache process with empty realpath cache: % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 50.78 1.157452 337 3434 28 stat 32.58 0.742656 628 1182 425 open 9.29 0.211788 762 278 1 lstat 3.17 0.072322 0 237865 write 2.45 0.055839 490 114 13 access 0.45 0.010262 43 237 brk 0.34 0.007725 10 811 74 read 0.28 0.006340 9 679 fstat 0.22 0.005069 18 281 poll 0.20 0.004533 6 698 getdents 0.09 0.001960 10 190 mmap 0.05 0.001065 14 74 accept4 0.04 0.001000 333 3 chdir 0.03 0.000750 4 190 munmap 0.01 0.000339 0 836 close 0.01 0.000247 3 75 writev 0.00 0.000068 0 611 fcntl 0.00 0.000063 1 77 shutdown 0.00 0.000000 0 1 lseek 0.00 0.000000 0 5 rt_sigaction 0.00 0.000000 0 1 rt_sigprocmask 0.00 0.000000 0 3 setitimer 0.00 0.000000 0 5 socket 0.00 0.000000 0 5 5 connect 0.00 0.000000 0 74 getsockname 0.00 0.000000 0 15 setsockopt 0.00 0.000000 0 5 getcwd 0.00 0.000000 0 1 futex ------ ----------- ----------- --------- --------- ---------------- Strace after realpaths are cached % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 60.14 1.371006 484 2831 28 stat 31.79 0.724705 627 1155 425 open 3.53 0.080354 0 237865 write 2.65 0.060433 530 114 13 access 0.43 0.009913 99 100 brk 0.38 0.008730 11 804 74 read 0.35 0.007910 12 675 fstat 0.30 0.006775 10 654 getdents 0.13 0.003065 11 281 poll 0.09 0.002000 333 6 1 lstat 0.07 0.001545 2 807 close 0.05 0.001063 14 74 accept4 0.04 0.001000 6 179 mmap 0.02 0.000404 2 179 munmap 0.01 0.000271 4 75 writev 0.01 0.000212 0 611 fcntl 0.01 0.000129 2 77 shutdown 0.00 0.000022 0 74 getsockname 0.00 0.000000 0 1 lseek 0.00 0.000000 0 5 rt_sigaction 0.00 0.000000 0 1 rt_sigprocmask 0.00 0.000000 0 3 setitimer 0.00 0.000000 0 3 socket 0.00 0.000000 0 3 3 connect 0.00 0.000000 0 15 setsockopt 0.00 0.000000 0 5 getcwd 0.00 0.000000 0 3 chdir ------ ----------- ----------- --------- --------- ---------------- Mount: nfs.xxx.xxx.xxx:/path/to/website/files on /path/to/website/files type nfs (rw,hard,intr,noac,vers=4,addr=xx.xx.xx.xx,clientaddr=xx.xx.xx.xx) Any help is, naturally, appreciated.
