  • Wget save cookies not working

    - by TrymBeast
    I've been trying to login in the pyload through the web api, but wget is not saving the cookies and I don't understand why. I'm using the following command: wget --delete-after --keep-session-cookies --save-cookies=my_cookies.txt --post-data="username=USERNAME&password=PASSWORD" http://localhost:8000/api/login But the content of my_cookies.txt is: # HTTP cookie file. # Generated by Wget on 2012-06-23 22:31:33. # Edit at your own risk. When I run the same command but in debug mode I get the following output that includes the set cookie in the header response: DEBUG output created by Wget 1.10.2 (Red Hat modified) on linux-gnueabi. --22:31:11-- http://localhost:8000/api/login Resolving localhost... 127.0.0.1 Caching localhost => 127.0.0.1 Connecting to localhost|127.0.0.1|:8000... connected.

  • Setting up Windows network on Xen

    - by samyboy
    I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings. Dom0 is a Debian Lenny currently hosting around 10 Linux virtual servers. Windows tells me I have a "limited connection". It can't get any DHCP response, nor access other hosts in the network Here is the Xen's client config file: kernel = '/usr/lib/xen-3.2-1/boot/hvmloader' builder = 'hvm' memory = '1024' device_model='/usr/lib/xen-3.2-1/bin/qemu-dm' acpi=1 apic=1 pae=1 vcpus=1 name = 'winexchange' # Disks disk = [ 'phy:/dev/wnghosts/exchange-disk,ioemu:hda,w', 'file:/mnt/freespace/ISO/DVD1_Installation.iso,ioemu:hdc:cdrom,r' ] # Networking vif = [ 'mac=00:16:3E:0A:D0:1B, type=ioemu, bridge=xenbr0'] # video stdvga=0 serial='pty' ne2000=0 # Behaviour boot='c' sdl=0 # VNC vfb = [ 'type=vnc' ] vnc=1 vncdisplay=1 vncunused=1 usbdevice='tablet' Server config (/etc/xen/xend-config.sxp) (network-script network-bridge) (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 512) (dom0-cpus 0) (vnc-listen '0.0.0.0') Since I use Debian I had to create a link like this: /etc/xen/qemu-ifup - /etc/xen/scripts/qemu-ifup What did I do wrong? Please tell me if you want some more info (logs, etc)

  • mysql command line not working

    - by Sandeepan Nath
    I have mysql running in my fedora system. I have xampp setup on the system and php projects present in the webspace are working fine. PhpMyAdmin is working fine. echoing phpinfo() in a PHP script also shows mysql enabled. But running mysql connect command mysql -u[username] -p[password] Gives this - bash: mysql: command not found How do I fix that? Any pointers? I guess I need to do some pointing (define some path in some file) so that my system knows that mysql is installed. What exactly do I have to do? Additional Details This system was someone else's and he is not available here. May be PHP/Mysql was setup already in the system. I just freshly extracted xampp for linux into /opt/lampp/ and have put all the above mentioned things (PHP projects and PhpMyAdmin) there. After doing that I had a socket problem (PhpMyAdmin was not working and showing this)- #2002 - The server is not responding (or the local MySQL server's socket is not correctly configured) I restarted lampp using ./lampp restart but problem remained. Then after turning on system today, I started lampp and everything worked just fine. No project issues anymore only command line Mysql not working

  • Is Unix not a PC Operating System?

    - by Corelgott
    I am doing my Bachelor at a university. In a written assignment the professor posted the task: "Name 3 PC-Operating Systems". Well, I went on an included a variety of OS (Linux, Windows, OSx) including Unix & Solaris. Today I recieved a mail from my prof saying: Unix is not a PC-Operating System. Many Unix-variants are not PC-hardware compatible (like AIX & HP-UX. About Solaris: there was one PC-compatible version...) I am kind of suprised: Even if may Unix-variants are Power-PC and different bit-order – Those don't stop being PCs now, right? The question was given in a written assigment! It was not a question that came up during lecture! Due to the original task being in German, I'll include it just to make sure nobody suspects an error in the translation. Frage: Nennen Sie 3 PC-Betriebssysteme. Antwort: Unix ist kein PC-Betriebssystem, viele Unix-Varianten sind nicht auf PC-Hardware lauffähig (AIX, HP-UX). Von Solaris gab es mal eine PC-Variante.

  • KVM and JBoss Java Application Server

    - by Jason
    We have a large Xen deployment running on both RHEL and CentOS and have recently started looking at KVM since this is where it looks like the future of VM's are on Linux. We can load the server and get everything running without an issue. However when we load up a new one with JBoss (4.2 Community edition, Sun JDK 6) and load a large EAR the server goes a little crazy. The %sy will jump to 80-99% and just hang for large periods of time we see a similar jump in %us on the host machine. We though at first this might be I/O as it seems to happen at start of JBoss but then would "cool down" after everything got loaded. We did some tests by extracting some large tar.gz files and using jar -xvf on the ear but could not re-create. Then we starting thinking this might be some type of memory access issues. We loaded a c-program that would generate a lot of memory activity and sure enough we saw the spikes again. Not as high mind you but we did see it jump. We then wrote a small java program to do the same thing and sure enough we saw it jump again. Any thoughts on what might be causing this? Is this just the way KVM works? As a side note we do NOT see this behavior on any other setup. Xen, VMWare and/or native iron. The system does seem a bit slower than our Xen / VMware ones.

  • Not able to find scripts present in /etc/profile.d directory [on hold]

    - by priya
    I am using Red Hat Linux 6.0 ... using davinchi board. I have to change system clock resolution so I am changing (HZ) env var. For this I have written script so that I can change HZ = 1000 n insert that script in /etc/profile.d and write code for loop in /etc/profile so that while running as usual /etc/profile can load the scripts present in /etc/profile.d. But when I am logging into the system at root level then showing error as "-bash: ./etc/profile.d/resolution.sh(my script name): No such file or directory Also here why it is showing ./etc and not /etc . Is something related to that?? Also I tried to add script in /etc/init.d but still no change in value of HZ takes place. Please tell where to change so that this env var can get changed. The script(resolution.sh) written has :- #!/bin/bash export HZ=1000 The content of /etc/profile which I entered is: if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then .$i fi done unset i fi And the output of grep command is -rw-r--r-- 1 root root 535 Feb 4 2004 profile -rwxr-xr-x 2 root root 4096 Feb 2 2004 profile.d

  • Ways to have audio output without wires

    - by viraptor
    I'm trying to find a way of using my home speakers/amp without actually having to connect them. There are two laptops that use them normally (so I don't like changing the connection all the time) and I'd rather move the speakers to a place that's away from the couch. I'm not sure how to do this though... The options I can think of are: some kind of wireless jack-jack connection finally getting a media server Unfortunately I can't find any good product for the first solution. I've seen some headphones which have the receiver integrated and a separate transmitted, so in general the idea is already out there, just not the way I need ;) I've seen also http://www.miccus.com/products/blubridge-mini-jack, but I'd have to have a compatible receiver which I can't find on its own (maybe there's some application that the media server could use?). As far as media server goes... many of the plug servers look really interesting, but I'm not sure how to create an audio output and how to redirect the input really. None of the plug servers I've seen so far advertises the option of audio output jack port. I think this part could be fixed by getting one with an usb port and a separate cheap usb soundcard. I hope that input can be sorted out in some rather simple way. I've got Linux running on both laptops so I hope that would be possible to configure jack/pulse/whatever to use the remote endpoint, or even write a simple local-/dev/dsp:network:media-server-/dev/dsp forwarder. So the main question is... are there better ways? Are there any out of the box solutions? Or maybe this was already done by someone and described somewhere?

  • Fedora 12 on Vmware network disabled on restore

    - by Chaitanya
    I have a fedora 12 guest running on VMWare on windows 7. I use it mainly for the occasional linux dev. Whenever I restart the guest, networking works fine. But if I close the VMware player and save state, the next time I start the image, networking is disabled (red x on the network icon. message saying networking disabled). I can't seem to find a way to restore networking. I have to reboot the guest to get my network access back again. My Ubuntu image doesn't have this problem. I can close the player and when I re run the image, I can pick up where I left off, with all the open firefox windows and application windows as I left them. Fedora saves state, but doesn't seem to enable networking. There is a relevant warning I have seen "SELinux is preventing /sbin/ifconfig "read" access to/var/run/vmware-active-nics." But I am not sure how to solve it. I know fedora isn't officially supported by VMware, but it seems to be working fine for the most part and meeting my needs, except for this one little issue. Any help would be much appreciated.

  • Ubuntu VM "read only file system" fix?

    - by David
    I was going to install VMWare tools on an Ubuntu server Virtual Machine, but I ran into the issue of not being able to create a cdrom directory in the /mnt directory. I then tested to see if it was just a permissions issue, but I couldn't even create a folder in the home directory. It continues to state that it is a read only file system. I know a little about Linux, and I'm not comfortable with it yet. Any advice would be much appreciated.

  • Can any postfix guru assist me determine how emails are still being sent via my server from unauthorized sources?

    - by Dave
    Hi all, I'm getting a little concerned as I run a small server hosting a number of websites and manage the email for a few dozen people. Just recently though I've had a couple of notifications from spamcop alerting me that spam has been sent from my server, and when I have a look over the logs from time to time I can indeed see that there are many repeated attempts of mail being sent from my server. Most of the time it gets knocked back from the destination servers but sometimes its getting through. Unfortunately I'm not linux or postfix expert, I can get by but had though I had my machine locked down quite securely, I don't allow relaying, when I check the online DNS/MX tools they tend to report my server as being OK so I'm not sure where to take it now and hoping someone might be able to throw me a few pointers. I get lots of entries like this in my MAIL.INFO log Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 66B88257C12F: from=<>, size=3116, nrcpt=1 (queue active) Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 614C2257C1BC: from=<[email protected]>, size=2490, nrcpt=3 (queue active) and Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6471]: 0A316257C204: to=<[email protected]>, relay=none, delay=384387, delays=384384/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6470]: 5848C257C20D: to=<[email protected]>, relay=none, delay=384373, delays=384370/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) then there tends to be connection timeouts, so from what I see even though I had relaying disabled.. something is getting by and trying to send.. So if you can help that will be greatly appreciated, and any further logging/config info I can supply. Thanks

  • How can I mount dd image of a partition?

    - by Puneet Arora
    I created a dd image of a partition (containing an HFS+ FS) of one of my disks (and not the entire disk) a few days ago using the following command - dd conv=sync,noerror bs=8k if=/dev/sdc2 of=/path/to/img How can I mount it? I tried the following but it doesn't work - mount -o loop,ro -t hfsplus /path/to/img /path/to/mntDir It gives me mount: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so and dmesg | tail gives me - [5248455.568479] hfs: invalid secondary volume header [5248455.568494] hfs: unable to find HFS+ superblock [5248462.674836] hfs: invalid secondary volume header [5248462.674843] hfs: unable to find HFS+ superblock [5248550.672105] hfs: invalid secondary volume header [5248550.672115] hfs: unable to find HFS+ superblock [5248993.612026] hfs: unable to find HFS+ superblock [5248998.103385] hfs: unable to find HFS+ superblock [5249031.441359] hfs: unable to find HFS+ superblock [5249036.274864] hfs: unable to find HFS+ superblock Is there something wrong that I am doing? I tried searching on how to do this but all the results I get only talk about mounting a partition from within a full disk image, using the offset option with mount - none talk about the case where the image itself is that of a partition. Thanks. PS: I'm running 64bit Arch Linux, and the partition from the original disk /dev/sdc2 mounts fine.

  • Write Fedora.iso to USB and boot it from a Macbook

    - by MTilsted
    I have an .iso image of the full Fedora 16 install (Downloaded from http://fedoraproject.org/en/get-fedora-options#formats as "Fedora 16 DVD") and the question now is: How do I write it on a USB stick, so I can install it on my Mac book? I tried using DD as the install guide said, and that gave me a USB stick which can boot from my PC. But it can't boot from the Mac (The Mac start menu don't show it as a boot option). Edit: I downloaded a live install image, and did this (SSD is my USB 4GB thing) /sbin/mkdosfs -F 32 -n usbdisk /dev/dev/sdd1 sudo livecd-iso-to-disk --format --reset-mbr --efi /tmp/download/Fedora-16-i686-Live-KDE.iso /dev/sdd1 And this produced an image which can boot on my pc but not on my mac. This seems to indicate that the --efi is not working, because if it really was EFI it would not boot on a normal pc, would it? I then tried this: (Difference being that I write the image directory to /dev/sdd instead of /dev/sdd1) but this still will not boot on the Mac (it newer shows up at the startup screen on the Mac). sudo livecd-iso-to-disk --format --reset-mbr --efi /tmp/download/Fedora- PS: My host Linux is Fedora 13.

  • Virtual machines with failover setup

    - by kimmmo
    We have three servers and our plan is to run a number of virtual machines on them in such manner, that if one of the nodes blow up, we can either quickly or seamlessly get a spare running on another node. In addition to the normal networking, they're interconnected via dual 10Gbit NIC's, so networked raid/mirroring shouldn't be a problem. The guest VM's are mostly going to be running text mode linux, but of course it wouldn't hurt to be able to spin up a non-mission critical windows guest for running Visual Studio or checking IE compatibility of a web app. We've spent some time trying to get some magical cloud setup running using Stackops and Crowbar but it started to look like they were offering way too much and were too complicated for our needs. The next candidate, I think, is Ubuntu 11.04 server + KVM + Ganeti + Drbd, unless you can come up with a suggestion for a better solution that we have missed. Requirements: Installation should be simple or at least understandable without being in the dev team A browser interface for creating and managing VM's is a nice bonus Single node's hardware failure should cause minimal downtime for VM's that were running on that node Adding more nodes should be possible without shutting down the VM's.

  • Clarification on signals (sighup), jobs, and the controlling terminal

    - by asolberg
    So I've read two different perspectives and I'm trying to figure out which one is right. 1) Some sources online say that signals sent from the controlling terminal are ONLY sent to the foreground process group. That means if want a process to continue running in the background when you logout it is sufficient to simply suspend the job (ctrl-Z) and resume it in the background (bg). Then you can log out and it will continue to run because SIGHUP is only sent to the foreground job. See: http://blog.nelhage.com/2010/01/a-brief-introduction-to-termios-signaling-and-job-control/ ...In addition, if any signal-generating character is read by a terminal, it generates the appropriate signal to the foreground process group.... 2) Other sources claim you need to use the "nohup" command at the time the program is executed, or failing that, issue a "disown" command during execution to remove it from the jobs table that listens for SIGHUP. They say if you don't do this when you logout your process will also exit even if its running in a background process group. For example: http://docstore.mik.ua/orelly/unix3/upt/ch23_11.htm ...If I log out anyway, the shell sends my background job a HUP signal... In my own experiments with Ubuntu linux it seems like 1) is correct. I executed a command: "sleep 20 &" then logged out, logged back in and pressed did a "ps aux". Sure enough the sleep command was still running. So then why is it that so many people seem to believe number 2? And if all you have to do is place a job in the background to keep it running why do so many people use "nohup" and "disown?"

  • Managing per-user rc.d init scripts

    - by Steve Schnepp
    I want to delegate SysV init scripts to each user. Like the SysV init, each item in ${HOME}/rc.d starting with S will be launched on server start-up with the start argument. The same for the server shut-down with the one starting with K and with the stop argument. I thought about scripting it myself, but maybe there is already some kind of implementation out there1. In summary it would be a script in /etc/init.d/ that iterates through all the users and launches runparts as the user on the relevant scripts. The platform here is a Linux (Debian flavour), but I think the solution would be quite portable among various Unix-like platforms. Update: The point here is for users to be able to create their own init scripts that should be launch on their behalf when the system boots up. As Dan Carley pointed out, the services won't be able to access any system asset (priviledged ports, system logs, ...). 1. This way I don't have to think that much about all the subtle security implications such as script timeouts for example...

  • How do I ensure a process is running, even if it kills itself? (it needs to be restarted then)

    - by le_me
    I'm using linux. I want a process (an irc bot) to run every time I start the computer. But I've got a problem: The network is bad and it disconnects often, so I need to manually restart the bot a few times a day. How do I automate that? Additional information: The bot creates a pid file, called bot.pid The bot reconnects itself, but only a few times. The network is too bad, so the bot kills itself sometimes because it gets no response. What I do currently (aka my approach ;) ) I have a cron job executing startbot.rb every 5 minutes. (The script itself is in the same directory as the bot) The script: #!/usr/bin/ruby require 'fileutils' if File.exists?(File.expand_path('tmp/bot.pid')) @pid = File.read(File.expand_path('tmp/bot.pid')).chomp!.to_i begin raise "ouch" if Process.kill(0, @pid) != 1 rescue puts "Removing abandoned pid file" FileUtils.rm(File.expand_path('tmp/bot.pid')) puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) else puts "Bot up and running!" end else puts "Starting the bot!" Kernel.exec(File.expand_path('./bot.rb')) end What this does: It checks if the pid file exists, if that's true it checks if kill -s 0 BOT_PID == 1 (if the bot's running) and starts the bot if one of the two checks fail/are not true. My approach seems to be quite dirty so how do I do it better?

  • LVM and cloning HDs

    - by jcea
    Using Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy. Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess. If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes? Any suggestion? I guess I could repartition my external harddisk and change backup strategy from dd to rsync, but this disk has windows installed too, and I really would like to have a physical "real" copy.

  • Batch file to create many files with special characters

    - by MollyO
    Essential info: I have a file "DB_OUTPUT.TXT" with 304 lines that I need to turn into 304 files (one per line). Each line contains many special characters and may be up to tens of thousands of characters long. For these reasons, I'm having difficulty using a cmd.exe batch file (which limits the amount of input) and the echo command (which would try to execute each special character, short of me having to escape them all). I also have a file "DB_OUTPUT_FILENAMES.TXT" containing a distinct filename for each line-soon-to-be-file from "db_output.txt". So line 1 of DB_OUTPUT.TXT needs to be the body of a new file with a name equal to line 1 of DB_OUTPUT_FILENAMES.TXT. Extra info: As you may have guessed, DB_OUTPUT.TXT is output from a database; it contains 304 records with 6 or 7 columns at a fixed width with the last column being a SQL query. Each of these lines (db records) will be used as a script to create new database objects, which is why the special characters need to be preserved. Question: Is there a way to do this in a batch-like fashion? I'd be happy with either a Windows solution or a Linux one.

  • Cannot properly read files on the local server

    - by Andrew Bestic
    I'm running a RedHat 6.2 Amazon EC2 instance using stock Apache and IUS PHP53u+MySQL (+mbstring, +mysqli, +mcrypt), and phpMyAdmin from git. All configuration is near-vanilla, assuming the described installation procedure. I've been trying to import SQL files into the database using phpMyAdmin to read them from a directory on my server. phpMyAdmin lists the files fine in the drop down, but returns a "File could not be read" error when actually trying to import. Furthermore, when trying to execute file_get_contents(); on the file, it also returns a "failed to open stream: Permission denied" error. In fact, when my brother was attempting to import the SQL files using MySQL "SOURCE" as an authenticated MySQL user with ALL PRIVILEGES, he was getting an error reading the file. It seems that we are unable to read/import these files with ANY method other than root under SSH (although I can't say I've tried every possible method). I have never had this issue under regular CentOS (5, 6, 6.2) installations with the same LAMP stack configuration. Some things I've tried after searching Google and StackExchange: CHMOD 0777 both directory and files, CHOWN root, apache (only two users I can think of that PHP would use), Importing SQL files with total size under both upload_max_filesize and post_max_size, PHP open_basedir commented out, or = "/var/www" (my sites are using Apache VirtualHosts within that directory, and all the SQL files are deep within that directory), PHP safe mode is OFF (it was never ON) At the moment I have solved this issue with the smaller files by using the FILE UPLOAD method directly to phpMyAdmin, but this will not be suitable for uploading my 200+ MiB SQL files as I don't have a stable Internet connection. Any light you could shed on this situation would be greatly appreciated. I'm fair with Linux, and for the things that do stump me, Google usually has an answer. Not this time, though!

  • Create a partition table on a hardware RAID1 drive with [c]fdisk

    - by Lev Levitsky
    My question is, is there a reason for this not to work? Details: I have two 500 Gb drives, and my motherboard RAID support, so I created a RAID1 array and booted from a Linux live medium. I then listed the disks and, apart from the obvious /dev/sda, /dev/sdb, etc. there was /dev/md126 which, I figured, was the mirrored "virtual" drive. Its size was 475 Gb; I had seen that the size of the array would be smaller than 500 Gb when I was creating it, so no surprise there. I did cfdisk /dev/md126, created the necessary partitions and chose write. It's been about half an hour now, I think. It doesn't seem like it's ever going to finish. The only thing about cfdisk in dmesg is that it's "blocked for more than 120 seconds". Doing fdisk -l /dev/md126 in another terminal I see all three partitions I created and a note that "Partition 1 does not start on a physical sector boundary". The table is lost after reboot, though. I tried to partition /dev/sda individually, and it worked, the table was written in about a second. The "not on a physical sector boundary" message is there, too. EDIT: I tried fdisk on /dev/sda, then there were no messages about sector boundaries. After a reboot, I am able to use mkfs on /dev/dm126p1, etc. fdisk shows that /dev/md126 has the same partitions as /dev/sda (but /dev/sdb doesn't have any). But at some point ("writing superblock and filesystem accounting information") mkfs is also blocked. Using it on sda1 results in a "partition is used by the system" error. What can be the problem? EDIT 2: I booted a freshly updated system from a pendrive and was able to create partition table and filesystems on /dev/md126 without any apparent problems. Was it an issue with the support of the hardware? My MB is Asus P9X79.

  • Provisioning DELL servers using only linux tools

    - by Krist van Besien
    We have taken delivery of a bunch off Dell Poweredge Rack servers. Unfortunately when ordering it was neglegted to ask for dhcp to be enabled in the built in iDRAC controlers... So they are all stuck on the same IP address. Which means that I'll have to go to each of them individually and configure a new IP in the console... In the future I want to avoid that. Now Dell proposes to deliver the next batch with auto discovery enabled. As I understand this means that when the machine wakes up for the first time the iDRAC will request a DHCP address. The DHCP server then supposedly also provides a "provisioning" server, that provides it with a username and password, and a configuration to be applied. This would allow us to for example configure things like RAID automatically. However, I can't seem to find a way to set up such a provisioning server that does not involve setting up a windows machine. I want to use Linux tools exclusively. Is there a way to do this? I want to just rack servers, switch them on, and then do everything remotely. And that using only linux tools?
