  • Pain removing a perl rootkit

    - by paul.ago
    So, we host a geoservice webserver thing at the office. Someone apparently broke into this box (probably via ftp or ssh), and put some kind of irc-managed rootkit thing. Now I'm trying to clean the whole thing up, I found the process pid who tries to connect via irc, but i can't figure out who's the invoking process (already looked with ps, pstree, lsof) The process is a perl script owned by www user, but ps aux |grep displays a fake file path on the last column. Is there another way to trace that pid and catch the invoker? Forgot to mention: the kernel is 2.6.23, which is exploitable to become root, but I can't touch this machine too much, so I can't upgrade the kernel EDIT: lsof might help: lsof -p 9481 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAMEss perl 9481 www cwd DIR 8,2 608 2 /ss perl 9481 www rtd DIR 8,2 608 2 /ss perl 9481 www txt REG 8,2 1168928 38385 /usr/bin/perl5.8.8ss perl 9481 www mem REG 8,2 135348 23286 /lib64/ld-2.5.soss perl 9481 www mem REG 8,2 103711 23295 /lib64/libnsl-2.5.soss perl 9481 www mem REG 8,2 19112 23292 /lib64/libdl-2.5.soss perl 9481 www mem REG 8,2 586243 23293 /lib64/libm-2.5.soss perl 9481 www mem REG 8,2 27041 23291 /lib64/libcrypt-2.5.soss perl 9481 www mem REG 8,2 14262 23307 /lib64/libutil-2.5.soss perl 9481 www mem REG 8,2 128642 23303 /lib64/libpthread-2.5.soss perl 9481 www mem REG 8,2 1602809 23289 /lib64/libc-2.5.soss perl 9481 www mem REG 8,2 19256 38662 /usr/lib64/perl5/5.8.8/x86_64-linux-threa d-multi/auto/IO/IO.soss perl 9481 www mem REG 8,2 21328 38877 /usr/lib64/perl5/5.8.8/x86_64-linux-threa d-multi/auto/Socket/Socket.soss perl 9481 www mem REG 8,2 52512 23298 /lib64/libnss_files-2.5.soss perl 9481 www 0r FIFO 0,5 1068892 pipess perl 9481 www 1w FIFO 0,5 1071920 pipess perl 9481 www 2w FIFO 0,5 1068894 pipess perl 9481 www 3u IPv4 130646198 TCP 192.168.90.7:60321-www.**.net:ircd (SYN_SENT)

  • How do I configure freeSSHd on Windows Server 2008 so I can log in using ssh?

    - by Daryl Spitzer
    I've installed freeSSHd on a Windows Server 2008 box (following the instructions in How to install an SSH Server in Windows Server 2008), including: created a user named "dspitzer" with NTLM authorization opened an exception for port 22 in the Windows Firewall But when I try to connect (from a Mac OS X 10.5.8 command-line), I get permission denied after entering the password: $ ssh 12.34.56.78 [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied, please try again. [email protected]'s password: Received disconnect from 12.34.56.78: 2: Too many attempts. I've also tried: $ ssh [email protected] [email protected]'s password: Permission denied, please try again. [email protected]'s password: Permission denied, please try again. [email protected]'s password: Received disconnect from 12.34.56.78: 2: Too many attempts. I've also tried changing the authorization to "Password stored as SHA1 hash" and entering a simple password, but I get the same problem. And I've tried a different user name ("Administrator") with no luck. I've confirmed that I am connecting to the server I'm configuring—if I stop freeSSHd and try to connect I get: $ ssh 12.34.56.78 ssh: connect to host 12.34.56.78 port 22: Operation timed out I get the exact same results from a Linux command-line. Any advice or troubleshooting tips? Update: I tried disabling the firewall (in response to geeklin's comment) and it made no difference. Update #2: I no longer have this machine (I've changed employers), so I have no way of verifying the answers. I guess all I can do is make this question "community wiki".

  • Ipsec reload fails to load ipsec.conf Strongswan 5.0

    - by Quentin Swain
    I am having trouble configuring a connection to an Android device using a fedora 17 linux machine and strongSwanv5.0.1dr2. I have made some progress but when I try adding the configuration to support xauth authentication I receive an error when I try to reload the configuration file. I get a similar error for the value ikev1 for the keyexchange setting , and whenever i try to set a value for rightauth. Has anyone else had this problem The man page for ipsec.conf and the documentation on the strongswan wiki both indicated that these settings and values should be fine in 5.0.x.x. I could try setting authby but that is deprecated according to the documentation i read and the xauthpsk value isn't working. Any help is much appreciated thanks. can not load config '/etc/ipsec.conf': /etc/ipsec.conf:25: syntax error, unexpected STRING [leftauth] # /etc/ipsec.conf - Openswan IPsec configuration file # # Manual: ipsec.conf.5 # # Please place your own config files in /etc/ipsec.d/ ending in .conf version 2.0 # conforms to second version of ipsec.conf specification # basic configuration config setup # For Red Hat Enterprise Linux and Fedora, leave protostack=netkey protostack=netkey # Enable this if you see "failed to find any available worker" # nhelpers=0 plutodebug=all conn %default ikelifetime=240m #keylifetime=20m keyingtries=3 ikev2=no conn android left=10.1.12.212 right=10.1.12.140 leftxauthserver=yes leftauth=psk rightauth=xauth keyexchange=ikev1 type=tunnel pfs=no rekey=no auto=start ike=aes256-md5;modp1024 phase2=esp ikev2=no #You may put your configuration (.conf) file in the "/etc/ipsec.d/" #include /etc/ipsec.d/*.conf

  • Changes made to cli's php.ini not taking effect

    - by Sandeepan Nath
    I have two php.ini files - /etc/php.ini which loads in case of cli /opt/lampp/etc/php.ini which loads in case of browser. I am able to use PHP's Mailparse extension after adding the line extension=mailparse.so in the /opt/lampp/etc/php.ini and restarting lampp. But I am not able to load the same in case of command line - getting PHP Fatal error: Call to undefined function mailparse_msg_create() in ... mailparse_msg_create() is a part of the Mailparse extension. I tried by relogging with the user after making the change and even restarting the system. What needs to be done so that the change takes effect. Update I checked that php -i | grep 'Configuration File' gives PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: cannot open shared object file: No such file or directory in Unknown on line 0 Configuration File (php.ini) Path => /etc Loaded Configuration File => /etc/php.ini Update 2 I copied the mailparse.so from /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626 and put it in /usr/lib/php/modules. I added extension=mailparse.so to /etc/php.ini as well. But it still showed this warning PHP Warning: PHP Startup: Unable to load dynamic library ... As told by Lekensteyn, I did ldd /usr/lib/php/modules/mailparse.so and got ldd: warning: you do not have execution permission for /usr/lib/php/modules/mailparse.so' So I gave execute permission. Then ldd /usr/lib/php/modules/mailparse.so showed linux-gate.so.1 => (0x00110000) libc.so.6 => /lib/libc.so.6 (0x0011d000) /lib/ld-linux.so.2 (0x003aa000) which looks normal. BUt now, running php command says PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: undefined symbol: mbfl_name2no_encoding in Unknown on line 0

  • Existing open source software for wireless mesh networking?

    - by user70352
    Hello! My goal: Build a wireless mesh network with some ALIX 2D2 (500 MHz AMD Geode LX800 x86 CPU, 256MB RAM, Atheros wireless card) Aside from working like a normal wireless mesh network users should be able to read/write data from/to the ALIX Boxes and the ALIX boxes should be able to process data. Questions: Should I try to flash dd-wrt x86, voyage linux (linux.voyage.hk) or something else? What (open source) software should I look into before I start? Should I use a 'server' for data storage and processing instead of the ALIX boxes? Is it even possible to use the ALIX boxes for routing AND data storage and processing? Final notes: Data can be anything, for example, I want to setup a wireless mesh using the OLSRD protocol so my whole town gets wifi and can access songs on the network. It's not for that, but that's the idea. I'm not afraid of programing, compiling or working with *nix. This is mostly 'for fun' rather than for practicality. Thanks in advance for any feedback.

  • BAT file will not run from Task Scheduler but will from Command Line

    - by wtaylor
    I'm trying to run a BAT script from Task Scheduler in Windows 2008 R2 and it runs for 3 seconds and then stops. It says it successfully completes but I know it doesn't. I can run this script from the command line directly, and it runs just fine. The bat file I'm running actually deletes files older than 7 days using "forfiles" then I'm mapping a network drive, moving the files across the network using robocopy, and then closing the network connection. I have taken the network and copy options out of the file and it still does the same thing. Here is how my file looks: rem This will delete the files from BBLEARN_stats forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_stats" -m *.* -d -17 -c "cmd /c del @file" rem This will delete the files from BBLEARN_cms_doc forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_cms_doc" -m *.* -d -14 -c "cmd /c del @path" rem This will delete the files from BBLEARN_admin forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_admin" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from BBLEARN_cms forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_cms" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from attendance_bb forfiles -p "E:\BB_Maintenance_Data\DB_Backups\attendance_bb" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from BBLearn forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN" -m *.* -d -18 -c "cmd /c del @path" rem This will delete the files from Logs forfiles -p "E:\BB_Maintenance_Data\logs" -m *.* -d -10 -c "cmd /c del @path" NET USE Z: \\10.20.102.225\coursebackups\BB_DB_Backups /user:cie oly2008 ROBOCOPY E:\BB_Maintenance_Data Z: /e /XO /FFT /PURGE /NP /LOG:BB_DB_Backups.txt openfiles /disconnect /id * NET USE Z: /delete /y This is happening on 2 servers when trying to run commands from inside a BAT file.

  • Pecl complies .so extensions for OSX built-in PHP and not MAMP

    - by Camsoft
    I've installed the sphinx binaries and libraries and am now trying to install the PECL sphinx module. My system is running OS X 10.6 with MAMP 1.8.2 installed. I try to install sphinx using the following command: sudo pecl install sphinx The PECL command outputs the following: running: phpize Configuring for: PHP Api Version: 20090626 Zend Module Api No: 20090626 Zend Extension Api No: 220090626 The versions above don't match the versions listed when doing a phpinfo(). It seems that PECL is trying to complie against the built-in version of PHP. If I ignore the errors and continue the it will successfully compile and place the sphinx.so file in: /usr/lib/php/extensions/no-debug-non-zts-20090626/sphinx.so when in fact it should be: /Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/ I've tried copying the sphinx.so file to the MAMP extensions dir but when I restart apache PHP displays the following warning: PHP Startup: Unable to load dynamic library '/Applications/MAMP/bin/php5/lib/php/extensions/no-debug-non-zts-20060613/sphinx.so I think this is because MAMP is 32bit and the built-in PHP is 64bit so PECL complies for 64bit. I might be completely wrong but I did read this when I goggled on the topic. Does anyone know how to get PECL to map to the MAMP version of PHP instead of the built-in version?

  • Accidentally deleted symlink libc.so.6 in CentOS 6.4. How to get sudo privilege to re-create it?

    - by Eric
    I accidentally deleted the symbol link /lib64/libc.so.6 - /lib64/libc-2.12.so with $ sudo rm libc.so.6 Then I can not use anything including ls command. The error appears for any command I type ls: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory I've tried $ export LD_PRELOAD=/lib64/libc-2.12.so After this I can use ls and ln ..., but still can not use sudo ln ..., sudo -E ln ..., sudo su or even su. I always get this err sudo: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory or su: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory It seems LD_PRELOAD works only for the current shell session of my account, but not for a new account like root or a new session. It's a remote server so I can not use a live CD. I now have a ssh bash session alive but can not establish new ones. I have sudo privilege, but don't have root password. So currently my problem is I need to run sudo sln -s libc-2.12.so libc.so.6 to re-create the symlink libc.so.6, but I can not run sudo without libc.so.6. How can I fix it? Thanks~

  • Dell Perc 6i with FreeBSD 8.1 errors with mfi0: COMMAND xxxxxxxx TIMEOUT AFTER xxx SECONDS

    - by jDempster
    We've recently bought two Dell PowerEdge R710 servers with Perc 6i controllers and 6x 135GB SAS Drives. We'd done some pretty extensive testing on a Dell PowerEdge R510 server with a Perc 6i and 4x 135GB SAS Drives running FreeBSD 8.1 for it's wonderful ZFS support and mfiutil. We hadn't had any problems with the R510 and had got to a point where we where happy with the performance of ZFS. Since running FreeBSD 8.1 on the R710 we've been getting errors from the RAID controller. mfi0: COMMAND 0xffffff80005d1770 TIMEOUT AFTER 6178 SECONDS This usually brings the system to a stand still. But it doesn't always happen, and performs very well up until it does happen. We've been running the disk as 3 mirrored drives striped in ZFS. So far we've noticed that running the drives with RAID10 on the RAID seems to work without errors (still testing). At first I thought hardware error as we'd been running FreeBSD on the R510 with the same controller without any issues. But both R710 have the same issue. All controllers are running the same firmware.

  • ssh tunnel - bind: Cannot assign requested address

    - by JosephK
    Trying to create a socks (-D) ssh tunnel - Linux box to Linux box (both centos): sshd running on remote side ok. From local machine we do / see this: ssh -D 1080 [email protected]. [email protected]'s password: bind: Cannot assign requested address (where 8.8.8.8 is really my server's IP and 'user' is my real username) I am logged into the remote side in this terminal-window. I can verify that the local port was unused prior to this command, and then used by an ssh process, after the command, via: netstat -lnp | grep 1080 So, unlike most googled-responses with this error, the problem would not seem to be the loopback interface assignment. If I try to use this tunnel with a mail client, the local-side permits the attempt (no 'proxy-failed' error), but no data / reply is returned. On the remote side, I do have "PermitTunnel yes" in my sshd_config (though 'yes' should be the default, anyway). Ideas or Clues? Here is the relevant debug-output OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * .... debug1: Authentication succeeded (password). debug1: Local connections to LOCALHOST:1080 forwarded to remote address socks:0 debug1: Local forwarding listening on 127.0.0.1 port 1080. debug1: channel 0: new [port listener] debug1: Local forwarding listening on ::1 port 1080. bind: Cannot assign requested address debug1: channel 1: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: Sending env LANG = en_US.utf8 Other clue: If I run a Virtual Box on the client running Windows, open a tunnel with putty in that box, that tunnel, to the same remote server, works.

  • NFS "Permission Denied" getting cached on NetApp Filer

    - by Christopher Karel
    We have a bunch of Linux boxes mounting NFS shares off a NetApp filer. From time to time, I will flub some part of the export configuration. Typo on one of the allowed hosts, incorrect IP address, etc, etc. No worries, this is usually done on a test system, or with brand new exports that aren't yet in production. However, I've found that once I've been denied permission to mount something from a Linux machine, the failure gets cached for as long as a day. I will correct the problem that was blocking the mount, re-export on the NetApp, and still not be able to mount the share. I'm pretty sure this caching is done at the NetApp side. It normally ages out after a day or so, but it really sucks having to wait until tomorrow to mount a share. I've tried exportfs -f on the NetApp, as well as dns flush. (I found both suggestions via Google) However, neither one works. I would sell my soul if someone could help out with a command/pagan ritual that would clear up this cache issue. --Christopher Karel

  • Upgrading Ubuntu to 9.04 breaks ATI video card driver, VESA and ati/radeon drivers

    - by Neil
    I upgraded my Ubuntu 8.10 to 9.04, and it not only broke the ATI proprietary fglrx driver, but also the ability to use the VESA or open-source ati or radeon drivers. I have an ATI RV610 which is an ATI Radeon HD 2400 XT. I have Linux Kernel 2.6.27-14-generic and 2.6.28-13-generic. With fglrx, vesa, ati and radeon, the Xserver hangs the machine as soon as it starts by invoking X or startx, which is seen by observing that caps lock doesn't work. There's nothing useful in /var/log/Xorg.0.log, no errors at all. This is with either kernel. When I download a new proprietary driver from ATI, I install it successfully on kernel 2.6.27, and it doesn't hang when X starts up, but it just shows a blank screen and does nothing. I also can't CTRL+ALT+Backspace out of X at this point. In all the years I've used ATI's Linux drivers, this has happened almost every time I've upgraded my kernel, but it's been fixable with much effort. This time I'm really stuck. Does anyone know how to fix these problems?

  • "Could not claim interface on camera: -6" when trying to connect usb camera (Kinect)

    - by rzetterberg
    I have installed the freenect library from openkinect.org. With that library there is a demo application which you can run from the terminal to test out the Kinect. However when I run this command I get the following output: richard@behemoth:~$ sudo freenect-glview Kinect camera test Number of devices found: 1 Could not claim interface on camera: -6 Could not open device This particular error is thrown by the library libusb by the function libusb_claim_interface and the error -6 corresponds to the LIBUSB_ERROR_BUSY. So my guess is that it has something to do with mounting the usb, rather than specifically the freenect library or the Kinect itself. So my question is how can I find out what resource is using this interface and how can I free it so that I can access it? Edit: What I have tried so far (just to be sure): Rebooted Plugged-out, plugged-in Tried different usb ports Restarted udev Additional information that might be useful: /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

  • How to boot Linux from a 16gb USB flash drive

    - by Chris Harris
    I'm trying to install Linux on a single partition of a USB flash drive that's larger than 4gb. The first place I went to is http://pendrivelinux.com. I can follow these instructions for installing Xubuntu 9.04 perfectly, which unfortunately break down when I try to scale it up beyond 4gb. There are several other tools to do this (unetbootin and usb-creator) which follow a very similar formula. I figured out that a big problem of mine was that all of these tools assume the USB drive is formatted in FAT32, which unfortunately cannot hold a single file larger than 4gb. This is unfortunate because I want to use just one partition, so that my persistance file, casper-rw, looks like one big partition to the OS once I've booted off of the USB drive. I then tried following a myriad of instructions involving formatting the drive as one large ext2 filesystem and using extlinux to create a single bootable ext2 file system. This doesn't work for me however, after about 20 attempts verifying and slightly tweaking the formula, I cannot seem to get a "good" bootable ext2 file system built. I'm not entirely sure what's going on, but it seems as though no matter how hard I try, I cannot get the ext2 file system to remain coherent after copying the Linux ISO contents over, copying the MBR, and executing extlinux to create the ext bootloader. Every time, after I follow these steps (in any order) and reboot, I get an unbootable USB drive. If I then mount the drive under Linux again, I see a mess of a file system (inodes have clearly been screwed up somewhere along the way). I suspected that the USB drive wasn't being fully flushed, so I tried using the "sync" and "unmount" commands before rebooting which didn't affect things at all. I guess I have several possible questions - but let's start with the obvious - is there something I'm missing to create a bootable ext2 USB flash drive that's large (e.g. 16gb)?

  • Install GRUB bootloader without installing Linux.

    - by Kavitesh Singh
    I have Windows 7 installed on the system and I want to create a separate WinPe bootable partition which system can fallback when things go wrong. Now Win7 does give this option and i might also edit the BCD store to make changes in the boot menu of Win7 or could use EasyBCD. I dont want to use these options as i need to customize hiding/unhiding of partitions at the time of booting etc. I search and found GRUB might the tool i am looking for. I want to use GRUB loader without any version of Linux installed on the system. Can someone guide me how i can install the GRUB on harddisk MBR and configure the bootmenu. I search internet and mostly i came across commands which search the GRUB on the harddisk because of existing linux installation and then try to repair it. In my case there is no Linux at all. I have Ubuntu 9.10 bootable CD/ OpenSUSE 11.2 liveCD and installation disc. Can i use them to install GRUB on my system?

  • How to run some commands after booting from ArchLinux disk? Or how to change some settings in .iso before booting?

    How to install Arch Linux with traditional installer with only ssh-access to server? There is nice guide: https://wiki.archlinux.org/index.php/Install_from_SSH I try test this on my home vps: Start VPS with any linux bootable cd and login to remote server (vps) wget http://mirrors.kernel.org/archlinux/iso/latest/archlinux-2010.05-netinstall-x86_64.iso dd if=archlinux-2010.05-netinstall-x86_64.iso of=/dev/sda reboot ... I see, it works but without ssh connection... I need make script, which will send this commands after reboot: aif -p partial-configure-network (and write some information about my server ip etc.) /etc/rc.d/sshd start (need to start sshd) echo "sshd: ALL" /etc/hosts.allow (to allow me login to server, by default deny all) passwd (by default its empty, can't login via ssh with empty password) Can I edit .iso or may be /dev/sda? May be I need write script, which will start after system boot and do this things or may be I can set this settings by default and system will start with correct settings (i think its possible at least in 2. and 3.). Thank you!

  • How to find out where or if MYSQL5 logs are stored on a machine WHM/Cpanel

    - by moi
    I have a WHM/Cpanel re-seller hosting account on a virtual private server (Linux). I have root access to the machine via SSH I am trying to locate a file that contains information that will help me to determine which users have accessed what db and from which hosts. I would imagine this kind of data is stored in a log file somewhere. The MySQL page says: The general query log - Established client connections and statements received from clients See: http://dev.mysql.com/doc/refman/5.0/en/server-logs.html It also says: By default, all log files are created in the mysqld data directory. So, I am am NOT asking where are the general query log logs stored, (cos I expect I will get answers saying "it depends") Please help me work out: "How can go about finding out where MySQL general query log logs are stored on a linux machine" Couple of things i've already tried: I looked at /etc/my.cnf it was a tiny file that only contained the following info: [mysqld] skip-bdb skip-innodb set-variable = max_connections=500 safe-show-database ~ ~ I have looked in: /var/lib/mysql/ But I could not see any log-like file names in that directory. Any clues on this would be most welcome.

  • Boot ISO image from GRUB4DOS on EFI machines

    - by Vladimir Tikhomirov
    I failed with loading ISO image (non-distro) from GRUB2 from USB stick, but found the way how I can boot the GRUB4DOS and then load the image from there. However, it doesn't work all the time and the questions is WHY it doesn't? Environment and loading process: We need to have EFI machine, USB stick, booting ISO, GRUB2 and GRUB4DOS. Last 3 on USB stick. Boot: USB - EFI loader - GRUB2 - GRUB4DOS - ISO image Configuration files To boot GRUB4DOS I use this from grub.cfg: menuentry "image.iso" { linux /syslinux/grub.exe --config-file="/menu.lst" } My menu.lst is here: timeout 20 default 0 title image.iso find --set-root --ignore-floppies --ignore-cd //image.iso map --heads=0 --sectors-per-track=0 //image.iso (hd32) map --hook chainloader (hd32) This works perfectly with Legacy machines. However, when I come to GRUB4DOS, I don't see the menu with image.iso, I see only GRUB command line. That means that my menu.lst didn't load. Why is it like this? Background and ideas I have an idea that GRUB4DOS doesn't recognize my USB stick as a device. I tried the command find and got (hd0,0), (hd0,1), (hd0,2), (rd). When I tried to set root to any of these devices I don't see fat file system, how it was with Legacy machines. The root device is (hd0,0), which has ntfs file system which should be partition with Windows. EFI machines support only GRUB2, so I can't boot GRUB4DOS straight away. Please, don't suggest anything like this, because my image doesn't have kernel. You can imagine that you load HDAT2 or Hiren's boot cd, for example. menuentry "Blancco Blancco5.iso" { set isofile="/image.iso" loopback loop $isofile set root=(loop) linux /isolinux/vmlinuz isofile=$isofile splash quiet initrd /isolinux/initrd }

  • Configure Plesk only for Tomcat-Java

    - by AJIT RANA
    I need to configure tomcat on Linux dedicate server only for Java project through Plesk . Following services is running on it. '1.Apache on port 80 ' '2.Tomcat on port 8080/9080' '3.Mysql on port 3306 ' Now problem is this, i need to run only java project on this server from port 80 .this time user type my site name then default page call index.html or .php file from root directory of Apache. so how it can be possible to run java project from this server default port 80 after deploye .war(java project) file to this server. Because user who wants to access my site does not know its port number for Tomcat as here is 9080 and also deploy file name. Pls look below for detail about problem Suppose my sit name is www.example.com and hosted on Linux dedicate server with Plesk install on it with Apache, Tomcat and Mysql. Now for running my java project on it, i need to enter www.example.com:9080/java_projrect_name/ in browser. So how can i run this project only from URL www.example.com and it will call default file .jsp from java_project_name directory. I do not want to enter port number and java_project_name in url and my client who wants to access this project did not know about port number as well as project name . He knows only about URL as www.example.com and when he browses it then it should call default page from java_project directory. So to implement this what should we need to do? Pls help. Thanks

  • Help diagnosing Likewise Open Active Directory authentication problem

    - by purpletonic
    I have two servers which were up until recently authenticating against the companies Active Directory Domain controller. I believe a recent change to the Active Directory administrator password caused the servers to stop authenticating against AD. I tried to add the servers back to the domain using the command: domainjoin-cli join example.com adusername this seemed to work without complaints, but when I try to login via ssh with my domain account, I get an invalid password error. When I run the command: lw-enum-users it prints all of the domain users, and looking up my own account, I see that it is valid and my password hasn't expired. I also ran lw-get-status and received the following: LSA Server Status: Agent version: 5.0.0 Uptime: 0 days 3 hours 35 minutes 46 seconds [Authentication provider: lsa-activedirectory-provider] Status: Online Mode: Un-provisioned Domain: example.com Forest: example.com Site: Default-First-Site-Name Online check interval: 300 seconds \[Trusted Domains: 1\] \[Domain: EXAMPLE\] DNS Domain: example.com Netbios name: EXAMPLE Forest name: example.com Trustee DNS name: Client site name: Default-First-Site-Name Domain SID: S-1-5-24-1081533780-4562211299-822531512 Domain GUID: 057f0239-7715-4711-e64b-eb5eeed20e65 Trust Flags: \[0x001d\] \[0x0001 - In forest\] \[0x0004 - Tree root\] \[0x0008 - Primary\] \[0x0010 - Native\] Trust type: Up Level Trust Attributes: \[0x0000\] Trust Direction: Primary Domain Trust Mode: In my forest Trust (MFT) Domain flags: \[0x0001\] \[0x0001 - Primary\] \[Domain Controller (DC) Information\] DC Name: dc1.example.com DC Address: 10.11.0.103 DC Site: Default-First-Site-Name DC Flags: \[0x000003fd\] DC Is PDC: yes DC is time server: yes DC has writeable DS: yes DC is Global Catalog: yes DC is running KDC: yes [Authentication provider: lsa-local-provider] Status: Online Mode: Local system Anyone got any ideas what might be occurring?

  • fail2ban Error Gentoo

    - by Mark Davidson
    Hi All I've recently setup a new VPS running Gentoo (My first time using the distro so please forgive me is this is a really easy one) and as I've done with other servers installed fail2ban. Setting it up to block the host via iptables, on too many unsuccessful logins with ssh. However I'm getting a strange error that I can't quite solve. When I start fail2ban I get these lines in the error log 2009-11-13 18:02:01,290 fail2ban.jail : INFO Jail 'ssh-iptables' started 2009-11-13 18:02:01,480 fail2ban.actions.action: ERROR iptables -N fail2ban-SSH iptables -A fail2ban-SSH -j RETURN iptables -I INPUT -p tcp --dport ssh -j fail2ban-SSH returned 100 If I try and force a ban these errors show up in the log and the host is not banned 2009-11-13 11:23:26,905 fail2ban.actions: WARNING [ssh-iptables] Ban XXX.XXX.XXX.XXX 2009-11-13 11:23:26,929 fail2ban.actions.action: ERROR iptables -n -L INPUT | grep -q fail2ban-SSH returned 100 2009-11-13 11:23:26,930 fail2ban.actions.action: ERROR Invariant check failed.

Thanks a lot in advance

  • How to list rpm packages/subpackages sorted by total size

    - by smci
    Looking for an easy way to postprocess rpm -q output so it reports the total size of all subpackages matching a regexp, e.g. see the aspell* example below. (Short of scripting it with Python/PERL/awk, which is the next step) (Motivation: I'm trying to remove a few Gb of unnecessary packages from a CentOS install, so I'm trying to track down things that are a) large b) unnecessary and c) not dependencies of anything useful like gnome. Ultimately I want to pipe the ouput through sort -n to what the space hogs are, before doing rpm -e) My reporting command looks like [1]: cat unwanted | xargs rpm -q --qf '%9.{size} %{name}\n' > unwanted.size and here's just one example where I'd like to see rpm's total for all aspell* subpackages: root# rpm -q --qf '%9.{size} %{name}\n' `rpm -qa | grep aspell` 1040974 aspell 16417158 aspell-es 4862676 aspell-sv 4334067 aspell-en 23329116 aspell-fr 13075210 aspell-de 39342410 aspell-it 8655094 aspell-ca 62267635 aspell-cs 16714477 aspell-da 17579484 aspell-el 10625591 aspell-no 60719347 aspell-pl 12907088 aspell-pt 8007946 aspell-nl 9425163 aspell-cy Three extra nice-to-have things: list the dependencies/depending packages of each group (so I can figure out the uninstall order) Also, if you could group them by package group, that would be totally neat. Human-readable size units like 'M'/'G' (like ls -h does). Can be done with regexp and rounding on the size field. Footnote: I'm surprised up2date and yum don't add this sort of intelligence. Ideally you would want to see a tree of group-package-subpackage, with rolled-up sizes. Footnote 2: I see yum erase aspell* does actually produce this summary - but not in a query command. [1] where unwanted.txt is a textfile of unnecessary packages obtained by diffing the output of: yum list installed | sed -e 's/\..*//g' > installed.txt diff --suppress-common-lines centos4_minimal.txt installed.txt | grep '>' and centos4_minimal.txt came from the Google doc given by that helpful blogger.

  • TomTom GO & Ubuntu Linux: impersonating a GPRS phone with dund

    - by Broam
    Background: I've called TomTom support, and they don't support Linux. I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work. However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering. However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4. I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way. Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine. I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure. My Question: I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on? Update: apparently dund is a legacy tool that's going away. What replaces it?

  • NVidia ION and /dev/mapper/nvidia_... issues.

    - by Ritsaert Hornstra
    I have an NVidia ION board with 4 SATA ports and want to use that to run a Linux Server (CentOS 5.4). I first hooed up 3 HDs (that will be a RAID5 array) and a forth small boot HD. I first started to use the onboard RAID capability but that does not work correctly under Linux: the raid capacity is not a real RAID but uses lvm to define some arays. After setting the BIOS back to normal SATA mode and whiping the HDs, the first boot harddisk (/dev/sda) is seen as /dev/sda BEFORE mounting and after mounting as /dev/mapper/nvidia_. CentOS is unable to install on it (and grub is not installable on it either). So somehow the harddisk is still seen as if it belongs to some lvm volume. I tried to clean out the HD by issuing a few dd if=/dev/zero of=/dev/sda commands to wipe the starting cylinders and final cylinders but to no avail. Did anyone see this problem and did anyone find a solution? UPDATE When I create only a single ext3 partition on the first HD (/dev/mapper/nvidia_...) no LVM partitions are seen and I can boot from /dev/mapper/nvidia_.... Now the next step is to see how I can get rid of this folly.
