  • wget mirroring, subdomains and directories and cookies

    - by Jimmu
    Hi all, I have an account on a web page that is now "full" (ie I have used up all my allocated space) and I would like to make a mirror of that site. wget seems like the thing to use. The problem is that I would only like to mirror the sites the lie within this directory http://user.domain.com/room/2324343/transcript/ (and sub-directories). Whilst saving the correct stylesheets, javascripts and css etc which exist in different directories. There as also uploaded files that are linked to within the pages in the transcript directory (on different directories) that I would like to download/mirror (theses are in a variatey of formats .exe, .py, .png, .app (and many more)). There are also images that are on different severs that are on these pages. Also I would like it if the links (which are sometimes relative , sometimes absoulute (but to internal things), sometimes external ) worked correctly so that if they link to things that have been downloaded(mirrored) they work fine (without internet connection), but if they link to things that are external or havent been mirrored they link to the external site. Basically so they work as expected. Another problem is that you have to log in to acess the site. Can wget be used to acomplish this or is there a better way? either way how do I achive this? (I have asked this question at stackoverflow.com/questions/2190115/wget-mirroring-subdomains-and-directories-and-cookies but it was recommended that I try asking it here)

  • WebDav issue with Mac OS X 10.5.3 onwards

    - by svnr
    We upgraded to Mac OS X 10.5.3 and getting problem when uploading files (PUT) to a webdav server (the server is Apache running on a Windows environment). When we drag and drop on to a webdav folder using Finder we get a -36 error. When looking at the stack trace of the web server the problem is due to INVALID CRLF or some times getting the following error. Both the stack point to error when copying the stream. When googled found that it is because the Mac changed to Transfer-Encoding to 'Chunked' ClientAbortException: java.net.SocketException: Software caused connection abort: socket write error at

  • How do I host multiple independent, secured SharePoint sites (WSS 3.0) without using Active Directory on the same server?

    - by Kyle Noland
    I have a SharePoint site set up on one of my networks to service Active Directory users. To be clear, this is a Windows SharePoint Services 3.0 installation running on Windows Server 2003 Standard. It is not an option to upgrade the server or SharePoint version. Management would like to create several new sites, one for each of a handful of clients. These sites will be used like "dropboxes" or FTP sites so that my company can make large files available to outside contacts, and vice versa. Here are my requirements: I do not want to have to create Active Directory accounts for each external contact. If possible, I would like to store the external usernames and passwords in a database that I can write a small GUI for so that management can handle adding their own external contacts. Each client site must be sandboxed from each other and from my main company SharePoint site. I would like to keep everything running on port 80 and be able to access the sites as either clientname.mycompany.com or www.mycompany.com/clientname If anybody has ever done this I would really appreciate hearing about any lessons you learned and suggestions for how to set this up.

  • Using Upstart to manage Unicorn w/ rbenv + bundler binstubs w/ ruby-local-exec shebang

    - by codykrieger
    Alright, this is melting my brain. It might have something to do with the fact that I don't understand Upstart as well as I should. Sorry in advance for the long question. I'm trying to use Upstart to manage a Rails app's Unicorn master process. Here is my current /etc/init/app.conf: description "app" start on runlevel [2] stop on runlevel [016] console owner # expect daemon script APP_ROOT=/home/deploy/app PATH=/home/deploy/.rbenv/shims:/home/deploy/.rbenv/bin:$PATH $APP_ROOT/bin/unicorn -c $APP_ROOT/config/unicorn.rb -E production # >> /tmp/upstart.log 2>&1 end script # respawn That works just fine - the Unicorns start up great. What's not great is that the PID detected is not of the Unicorn master, it's of an sh process. That in and of itself isn't so bad, either - if I wasn't using the automagical Unicorn zero-downtime deployment strategy. Because shortly after I send -USR2 to my Unicorn master, a new master spawns up, and the old one dies...and so does the sh process. So Upstart thinks my job has died, and I can no longer restart it with restart or stop it with stop if I want. I've played around with the config file, trying to add -D to the Unicorn line (like this: $APP_ROOT/bin/unicorn -c $APP_ROOT/config/unicorn.rb -E production -D) to daemonize Unicorn, and I added the expect daemon line, but that didn't work either. I've tried expect fork as well. Various combinations of all of those things can cause start and stop to hang, and then Upstart gets really confused about the state of the job. Then I have to restart the machine to fix it. I think Upstart is having problems detecting when/if Unicorn is forking because I'm using rbenv + the ruby-local-exec shebang in my $APP_ROOT/bin/unicorn script. Here it is: #!/usr/bin/env ruby-local-exec # # This file was generated by Bundler. # # The application 'unicorn' is installed as part of a gem, and # this file is here to facilitate running it. # require 'pathname' ENV['BUNDLE_GEMFILE'] ||= File.expand_path("../../Gemfile", Pathname.new(__FILE__).realpath) require 'rubygems' require 'bundler/setup' load Gem.bin_path('unicorn', 'unicorn') Additionally, the ruby-local-exec script looks like this: #!/usr/bin/env bash # # `ruby-local-exec` is a drop-in replacement for the standard Ruby # shebang line: # # #!/usr/bin/env ruby-local-exec # # Use it for scripts inside a project with an `.rbenv-version` # file. When you run the scripts, they'll use the project-specified # Ruby version, regardless of what directory they're run from. Useful # for e.g. running project tasks in cron scripts without needing to # `cd` into the project first. set -e export RBENV_DIR="${1%/*}" exec ruby "$@" So there's an exec in there that I'm worried about. It fires up a Ruby process, which fires up Unicorn, which may or may not daemonize itself, which all happens from an sh process in the first place...which makes me seriously doubt the ability of Upstart to track all of this nonsense. Is what I'm trying to do even possible? From what I understand, the expect stanza in Upstart can only be told (via daemon or fork) to expect a maximum of two forks.

  • Networking Home Office

    - by Matt
    I'm in the process of building an office in my garden. It's about 25m away from my house. I'd like to run a wired network connection to the office. I'd rather not go down the powerline route, as speeds don't seem great, and I'm likely to want to be moving a lot of data around on the internal network. I have an electrician who is running armoured electrical cable to the office, and is providing conduit for me to run network cable. My questions are: 1) What type of cable to run 2) How I terminate/connect it at both ends I could get something like armoured cat6 utp solid core (like this: http://www.netstoredirect.com/cat6-cable/289166-external-armoured-cat6-utp-solid-cable-price-per-metre.html) which seems fairly robust, but then I have to terminate it. Additionally, where the cable enters my house, there is about another 15m to where my router is situated. I also read this artice: http://www.audioholics.com/audio-video-cables/bjc-cat-network-cable-quality-interview which scared me into realising I don't know what I'm doing!! particularly with termination. Or I could get an "cat6 external patch cable" (e.g http://www.netstoredirect.com/rj45-network-cables/239231-external-cat6-utp-ldpe-rj45-patch-leads.html) and run that in the conduit, and work out how to terminate it at the house end. At the office end I guess I can just plug it into a switch. Any help? Thanks

  • How to connect through a proxy using Remote Desktop?

    - by scottmarlowe
    So I've got a home server running Windows Server 2003. I use a dual network card setup and Routing and Remote Access to link the internal, private network to the external connection. The external connection hooks directly to my cable modem (so no routers or other devices sitting between). The problem I'm having is that I can't connect remotely from a location outside the house (so connecting to the server's external connection) to the server using either Remote Desktop or VNC. I have enabled both ports in Routing and Remote Access's firewall to allow access, and I have enabled Remote Desktop in Windows Server 2003. The odd thing is that I can access my home server's SVN repository and I can even ping the server's IP. I am using the IP to attempt to connect, though I use a dyndns.com provided name to connect to my SVN repository, so it shouldn't make a difference (I know the IP is getting resolved correctly). Any ideas on where to start diagnosing this one? I haven't seen anything in my server's event log. If any other info is needed, let me know. Thanks. UPDATE: One last piece of information: We use a proxy server at work, which I'm nearly 100% sure is the culprit. I have a workaround--if I connect to our VPN (even though I'm already inside the building) I am able to connect to my home server. This is with VNC. However, is there a way to connect through a proxy using Remote Desktop? ONE MORE UPDATE: Indeed, it was the http proxy I'm sitting behind at work that was causing the issue. An acceptable workaround is to use my VPN connection to bypass the proxy, and I'm in!

  • Ubuntu 13.10 on Acer V5-472 with HD 4000

    - by Hyperboreus
    I have an Acer V5-472 with intel HD4000 graphics chipset and a built-in 1366*768 display. I have installed ubuntu 13.10 amd64 in legacy boot mode with an external monitor. Installation showed no problems, I can boot from HDD and log into my system. The internal display doesn't work and I have to use an external monitor. I have tried the following (found in other threads) to no avail: Setting grub option "acpi_backlight=vendor" or "acpi_osi=Linux" or both. Installing the intel HD drivers for Linux from their homepage. Running in circles, screaming and shouting. The internal display lights up (I can change the brightness with Fn-Left and Fn-Right) but that's all. When I boot, I get a purple splash screen and from then only the external monitor works. I read somewhere that this might be a problem with kernel 3.11? Has anybody ubuntu running on an Acer V5-472? Should I change ubuntu version or use 32-bit instead? In general, how can I get the internal display to work? Edit: The settings-display dialogue shows the internal display correctly with supported resolution of 1366.

  • MS Securily Essentials efficiency / usage, suspicious processes

    - by biggvsdiccvs
    I recently noticed that my (originally pretty fast) Windows 7 Pro laptop started getting slow and using a lot of CPU power for no apparent reason. A full scan by Microsoft Security Essentials revealed nothing. After some investigation, I found multiple instances of a strange process called urpev.exe and a couple of similar exe files sitting in subdirectories of Users//AppData/Roaming (this particular one was in a folder called Xyceowme). Description: "Mescrosift Visaal Studie 2010". Company name: "Mesrosift Corporatien". Is it a virus or something? :) Now, all of these exe files were scheduled to be started from the Task Scheduler by tasks with names like "Security Center Update - 1291373911" and similar. My user name was listed as the author of the tasks. I disabled the tasks, restarted the computer in safe mode and moved all of the exe files to quarantine for further investigation. All of this was done last night. I just scanned the files with Security Essentials again (not updated since yesterday) in the quarantine location and this time it found PWS:Win32/Zbot.gen!plock in urpev.exe (but not in the other exe files, which are most likely viruses, too). Category: Password Stealer Description: This program is dangerous and captures user passwords. Another strange process is browser.exe (not chrome.exe) by Google Inc., described as Google Chrome. I uninstalled Chrome but it's still there. It runs out of Users\\AppData\LocalLow\UIVoice\ToolMedium\browser.exe and if I move it in safe mode, it just reappears there, and multiple instances run. Needless to say, it I kill it, it just runs again. Couldn't see anything in Task Scheduler, but found a couple of references to it in the Registry Editor: HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/LowRegistry/Audio/PolicyConfig/PropertyStore/ HKEY_USERS/S-1-5-21-1685709306-872053864-2599010960-1002/Software/Microsoft/Internet Explorer/LowRegistry/Audio/PolicyConfig/PropertyStore/ Maybe it's a legit process, but seems kind of strange. For the time being, I suspended the process and killed all of the child processes when I booted up the laptop. I used Security Essentials to scan the system periodically, but obviously it's not effective at least against one virus. I had the "real-time protection" turned off. Would it help if it were turned on and how much of a nuisance would it be? I wonder if there is a better alternative to Security Essentials. Over the years I've used multiple antivirus products at home and especially at work and was not very happy with any of them. Apparently, asking for software recommendations or comparisons is taboo here, but I will mention that I installed Malware Bytes and it was able to find an quarantine a bunch of suspicious files, and at least some of which were truly infected, but when it scans the bogus security center update executables from Mesrosift Corporatien, it finds nothing wrong. Also, any thoughts on the browser.exe mystery? Neither MS Security Essentials nor Malware Bytes found anything wrong with that file. However, after I ran a Malware Bytes scan and quarantined everything it found suspicious and rebooted the laptop, the process did not run.

  • How do I install a different OS on a Compaq Presario cq56 with preinstalled SuSE 11?

    - by McCoy
    Thing is, I don't have a clue of Linux systems, I usually use WinXP. Bought a notebook with SuSE 11 on it, because I have my XP licence and thought I could install that if I found the chipset drivers for the hardware (which I'm not completely sure I have the right versions of). Then I thought I'd give it a shot with the SuSE, looked nice enough. But I can't get my external hd to work (tried force mount) and the banshee doesn't do anything like playing video. Since that is one of the two main purposes of this notebook, I need to get that to work. Tried downloading VLC player, but that only works with SuSE 11.1 upwards. So I downloaded a SuSE 11.3 and burned the iso. But surprise, no way the notebook would boot from cd. Same with the XP cd (considered setting up a dual boot). And no, I can't get to BIOS to reset to default, either. So I can basically do nothing else than going online with this thing and that's not enough for me (gamer in withdrawal, yikes!). I need at least to get to my firefox profile on the external hd and be able to watch video. Can somebody please help me? I think at this point I'd prefer to install XP and MAYBE the SuSE 11.3 after that. I'm not a native speaker, so please speak plainly, thanks. :) Edit: if this is impossible, could someone please help me with the external hd mount and video playback? Edit: Found out how to boot from cd by now. But still no XP, because I get bluescreen after bluescreen while setup is loading files. I guess it's the missing SATA drivers...

  • OpenSwan (IPSEC) on Fedora 13 with Snow Leopard as a client

    - by sicn
    I recently installed OpenSwan on my Fedora 13 machine. I want to use it to connect with Mac OS X with L2TP over IPSEC, unfortunately I am already stuck on the IPSEC-negotation part. My server is running behind a NATted firewall so my external IP differs from the server's IP. The server has a fixed IP on the network and the same is almost always valid for the clients (they are usually behind a NATted firewall). I installed OpenSwan on Fedora 13 and have following configuration: config setup protostack=netkey nat_traversal=yes virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12 oe=off nhelpers=0 conn L2TP-PSK-NAT rightsubnet=vhost:%priv also=L2TP-PSK-noNAT conn L2TP-PSK-noNAT authby=secret pfs=no auto=add keyingtries=3 rekey=no ikelifetime=8h keylife=1h type=transport left=my.servers.external.ip leftprotoport=17/1701 right=%any rightprotoport=17/0 IPSEC starts fine and listens to UDP 500 and 4500. These two ports are opened in the firewall and are forwarded fine to the server. In my /etc/ipsec.secrets file I have my.servers.external.ip %any: "LongAndDifficultPassword" And finally in my sysctl.conf (the redirect-entries are there because OpenSwan was strongly protesting about send/accept_redirects being active) I have net.ipv4.ip_forward = 1 net.ipv4.conf.all.send_redirects = 0 net.ipv4.conf.all.accept_redirects = 0 Running "ipsec verify" gives me "all greens" (except Opportunistic Encryption Support, which is DISABLED), however, when trying to connect my Mac gives me following in the logs: Nov 1 19:30:28 macbook pppd[4904]: pppd 2.4.2 (Apple version 412.3) started by user, uid 1011 Nov 1 19:30:28 macbook pppd[4904]: L2TP connecting to server 'my.servers.ip.address' (my.servers.ip.address)...

  • Changing default openVPN IP in linux server

    - by Lamboo
    The problem is that we have a public OpenVPN service. Pay €9.95 and you get an OpenVPN account at currently half a dozen of servers for a month. This means there are always and will always be some people who create a certain amount of abuse or trouble. On the long run, the external IP every OpenVPN user gets assigned is prohibited from editing Wikipedia, it might be banned by e-gold and on some popular webforums, one-click-hosters, etc. Not a pleasant experience for the 97% of our customers who use our service responsibly and legitimately to regain their privacy. So even if I could change the assigned external IP every few months; e. g. from 216.xx.xx.164 to 216.xx.xx.170, it would help us a lot to combat this abuse and to provide our paying clients with "fresh" IP addresses that aren't banned or restricted on some popular Internet sites and services, yet. Does anybody know how to change the first IP address assigned to the public interface in CentOS? So that e.g. OpenVPN in future doesn't give our OpenVPN clients the external IP 123.xx.xx.164 but rather 123.xx.xx.170?

  • Can't sync filesystem without reboot

    - by Fabio
    I'm having an issue with a linux server. Once a week the running mysql instance hangs and there is no way to fully stop it. If I kill it, it remains in zombie status and init does not reap its pid. The server is used for staging deployments and some internal tools, so it's not under heavy load. The only process constantly used id mysql and for this I think that it's the only process which suffer of this issue.

  • Balancing internal services using a Cisco CSS 11501

    - by Ladadadada
    First, the background to the problem: I have a Cisco CSS11501 that I am using to load balance a few web servers. These web servers have two network interfaces, one internal and one external and we are sending the requests to the internal interface. We have the CSS configured to do NAT because our webservers need to see the client's IP address. Because the TCP packets hit the webservers with a source address on the Internet, the webserver tries to send the packet back to the client over the external interface and not through the load balancer. In order to stop these requests being sent back out to the Internet via the external interface, we added a routing rule on these boxes so that all traffic with a source address on the internet will use the load balancer as the gateway. This part works fine. What I would also like to to is use the CSS as a load balancer for internal services such as our MySQL slaves. When I do this, I run into a similar problem; the TCP connection goes from the web server to the load balancer and then from the load balancer to the MySQL slave but the CSS spoofs a source address of the original webserver. The MySQL slave then tries to send the response directly to the webserver via the internal network and not via the load balancer. The ideal solution would be to tell the CSS not to do source address spoofing on the internal network and only do it for requests originating on the Internet. Is this possible ? Failing that, is there a way of directing the load balanced traffic back through the load balancer while keeping the other traffic (say SSH) purely on the internal network ? Is there another way of using the CSS11501 to load balance internal services ?

  • Set up lnux box for hosting a-z

    - by microchasm
    I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP: To upgrade PHP to the latest version, I had to look to another repo outside CentOS.

  • Sharepoint (WSS 3.0) on SBS 2008 broken.

    - by tcv
    I recently ran the Sharepoint Products and Technologies Wizard. I had hoped this would bring up Sharepoint and allow me to access it so I could begin to learn. But it's not working. Here is some data that I hope is relevant. I am doing all my testing on the SBS 2008 server itself. I changed the hostheader in IIS to reflect an external FQDN I plan to deploy. The SBS server is remote and there are no domain-connected workstations. If I browse "localhost" SSL, I can get to the site, albeit with a self-signed cert warning. If I attempt to connect via SSL using either the internal FQDN (.local), the External FQDN (.net) or any other permutation thereof, I am prompted for credentials three times but am not allowed access. My account is a domain admin. The site is inaccessible using port 80 whether using localhost, internal FQDN (.local), and external FQDN (.net) Right now, I suspect my problem is within IIS, but I don't know. My plan to publish the sharepoint site to the web so my partner and I can check documents in/out. Can someone help me get started in current direction?

  • My Boot order changed. Why?

    - by Chris
    I have a laptop running Windows XP SP3 with one internal hard drive partitioned into C: (system), D: (storage) and I have an external hard drive, F: (external drive). Yesterday the machine was running fine. Today, I go back to it and see that it's just showing a blinking cursor. Checked through the BIOS and the hard drive checked out fine. CTRL-ALT-DELETED the machine a few times, but I was never able to boot back into the operating system. I threw in a live CD and found out that the boot order of the drives has changed. The external drive is now C:, the system partiton is D:, and the storage partition is E:. Does anyone have any idea of how or why this would have occured? Auto system updates are turned off so there should have been no automatic reboot of the system overnight, and anti-virius runs on the machine and has found no infections before this occured. Edit When I was looking through the BIOS of the machine, I did see that the boot order was changed. But still the same question remains, what would have caused this to happen? I can't believe that a random reboot happened and totally changed my hard drive setup.

  • Postfix: Modify sender address based on recipient

    - by PJ P
    We have a Postfix server that receives mail from our application servers. Senders are in the form [email protected] (where host.fqdn can vary, depending on source server) and recipients can be internal or external users. Messages going to external users should have the sender changed to [email protected]. I have tried using canonical maps, but since that is handled by the cleanup daemon, before any transport decisions are made, it would affect all sender addresses. I have also tried creating a custom smtp transport with generic mappings and configuring transport_maps to use that custom smtp transport for external domains. However, generic mappings affect both sender and recipient addresses. Lastly, I've tried the following: Create a custom smtpd daemon that specifies sender canonical maps and a unique transport table. Send all externally addressed mail to that custom daemon. Ideally, sender canonical maps would transform the sender address and the unique transport table would relay messages to the internet. However, evidently, only one transport table can be used per Postfix instance. I want to avoid creating an entirely new Postfix instance to accommodate this rewriting. Any suggestions? (and thanks in advance)

  • Cannot connect to remote mail server for sending emails in ASP.NET

    - by Dave
    I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way. Update: For clarifying my setup: I have a Windows Server 2008 R2 with hMailServer installed (set up for some of the hosted domains) For the website I'm talking about I need to use an external mail server (totally different hosting provider) Apparently I was a bit off the track. It seems like it works when using connecting to the local mail server either with the host name "localhost" or "mail.somedomain.com" (while somedomain.com is set up in my mail server). But when using the host name of the external mail server ("mail.externaldomain.com") it seems like it tries to connect to the local server again, although this domain is not set up in the mail server. Thanks to Evan Anderson for the tip to use telnet - why I have not thought of it myself?... :-) Note, the website www.externaldomain.com is hosted on my server but the DNS entries are maintained by the other hosting provider. "externaldomain.com" is the only entry which points to my server all other records (MX, subdomains) are pointing to the other server. So I think the question is now, how do i bring my server to connect to the external mailserver. Do I have to configure this in my mail server or is it a windows server thing?

  • How to determine the Kerberos realm from an LDAP directory?

    - by tstm
    I have two Kerberos realms I can authenticate against. One of them I can control, and the other one is external from my point of view. I also have an internal user database in LDAP. Let's say the realms are INTERNAL.COM and EXTERNAL.COM. In ldap I have user entries like this: 1054 uid=testuser,ou=People,dc=tml,dc=hut,dc=fi shadowFlag: 0 shadowMin: -1 loginShell: /bin/bash shadowInactive: -1 displayName: User Test objectClass: top objectClass: account objectClass: posixAccount objectClass: shadowAccount objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson uidNumber: 1059 shadowWarning: 14 uid: testuser shadowMax: 99999 gidNumber: 1024 gecos: User Test sn: Test homeDirectory: /home/testuser mail: [email protected] givenName: User shadowLastChange: 15504 shadowExpire: 15522 cn: User.Test userPassword: {SASL}[email protected] What I would like to do, somehow, is to specify per-user basis to which authentication server / realm the user is authenticated against. Configuring kerberos to handle multiple realms is easy. But how to I configure other instances, like PAM, to handle the fact that some users are from INTERNAL.COM and some from EXTERNAL.COM? There needs to be an LDAP lookup of some kind where the realm and the authentication name is fetched from, and then the actual authentication itself. Is there a standardized way to add this information to LDAP, or look it up? Are there some other workarounds for a multi-realm user base? I might be ok with a single realm solution, too, as long as I can specify the user name - realm -combination for the user separately.

  • Swapping out a hardware firewall does the mac address get cached?

    - by Dan
    We need to replace a hardware firewall (cisco pix) and have a spare that we will use (temporarily). The firewall sits in front of a couple of web-servers colocated at a data-centre. The replacement will be configured with identical settings (external/internal IP addresses, configured ports etc.). When we swap the firewalls over, will this work immediately or will the old Pix's mac address be cached and the new firewall not be seen until the cache is cleared? (What is it though that is caching the address? Is it just the switch/router that our pix is connected to?) Reason for asking is a few years ago I had a smoothwall firewall in front of a lone server (the external IP of the smoothwall was also the external IP of the web-server). When I replaced the smoothwall with a pix, the IP address of the web-server stayed the same but it now had to be reached via the new firewall on a different IP. It took about 2-4 hours before the rest of the world could see that web-server again. I'm hoping for less downtime this time!

  • Asus K55VM usb 3.0 issue

    - by user2141481
    Good day superusers! I own the above laptop and I found out that there are some unknown and unusual issues with usb 3.0 ports. I haven't noticed anything strange until now. I got a new toshiba usb 3.0 external hdd and when I try to copy larger amount of data from my disk to the external hdd, the OS(windows 7) randomly starts ignoring the external hdd. It doesn't shut it down, it kinda just stops responding but the light on the hdd is still lit. I get an error that the files cannot be copied. I have reinstalled windows 7, installed all drivers(including intel chipset drivers of course) and the issue is still present. It acts normal when copying small amount of data. Also, I heard that some intel chipsets have an issue with usb, something about the connectors not transferring power when the usb device enters some kind of "low power mode" causing the device to stop responding and you need to plug it out and in again. But the thing is, my Intel® Chief River Chipset HM76 is not on the list of affected hardware(not ENTIRELY sure though). If anyone has any idea of what the problem to this might be, I'd be greatful. Edit: The hdd works perfectly fine even for large amounts of data if plugged in the usb 2.0 port!

  • Free software for backing up an attached network drive

    - by Richard
    My wireless router comes with a USB connector which allows me to plug an external hard drive in and it'll act as a Network Attached Storage. The problem is that I want to backup this hard-drive to the external drive of another computer so that if the NAS drive fails, I don't lose everything. However, Windows 7 Backup refuses to include the NAS as a location to backup. I can't fool it by mapping it to a drive letter either. Google presents lots of pages on how to backup files to a NAS, but not the other way around. Can anyone advise me on free software which can do incremental backups of a NAS drive to an external drive attached the computer it is running on? I'm aware of this question but the top answers have one or more of the following issues: They aren't free. The free version cannot backup a NAS. They cannot do incremental backups. They're just a script and therefore have limited other functionality (eg. disk space management, scheduling, compression, etc.etc.)

  • How can I take a one time full backup of a Windows Server without the need for a restore program?

    - by TheCleaner
    I have a Windows SBS server with about 500GB of data that I'm decommissioning but I'd like to take a final backup of the server and place it on an external USB drive. I already have multiple backups of the server on disk from the past but they are through Simpana Commvault. I'd like a backup that will simply copy the file structure, ACLs, timestamps, etc. as is to a NTFS volume on the external drive. This way if someone says "I need x file on the server you decommed" I can search the external drive real quick instead of firing up Commvault, cataloging, restore, etc. I know the built-in Windows backup is great, I just don't feel like running it for a restore job on this. I'd like an option where in the future it won't require a program to run a restore. Rather a simple mount of the drive will suffice. I believe I can use robocopy just fine, but I'm not sure if it will grab the Windows directory, system files, and full user profiles correctly even with the /ZB option. Options? Is Robocopy /E /ZB /COPYALL /DCOPY:DAT /MT:32 /R:5 /W:5 /LOG:copylog.log the way to go here?

  • Update a bootable OS X drive clone with rsync?

    - by Joe
    The question: is it possible to keep a boot-able backup drive clone of OS X updated with rsync? If rsync is not a viable option are there alternatives? The Setup: My situation is as shown above. One internal Samsung 840 SSD [120g] in use as my OS X 10.8 boot disk on a recent model Mac Mini. I have successfully cloned that drive with disk utility to a 125g partition of another HDD in an external USB 3 enclosure and at that point I am able to boot to it. The Goal: As my last system went out in a fiery blaze taking much valuable data with it, I have a new respect for a proper backup solution and really want to do this right. My goal is to achieve an automated differential backup/update from Disk A to Disk B while most importantly maintaining boot-ability on the external drive. And I would prefer to do this differentially to minimize stress on the drives. Hence rsync was the first thing to come to mind. What I have tried: following along with Jamie Zawinski's differential mac bootable backup solution running this manually initially worked - i tested it with only very miniscule file change and everything was fine / external booted and all. now after subsequent passes rsync fails throwing errors particularly relating to updating 'boot.efi' (not at the machine currently I will update the precise log message once I return home) is this a drive partition size issue? does rsync require more space? if it cant be done, are there any alternatives? i've heard whispers of dd

  • How do I install a different OS on a Compaq Presario cq56 with preinstalled SuSE 11?

    - by McCoy
    Thing is, I don't have a clue of Linux systems, I usually use WinXP. Bought a notebook with SuSE 11 on it, because I have my XP licence and thought I could install that if I found the chipset drivers for the hardware (which I'm not completely sure I have the right versions of). Then I thought I'd give it a shot with the SuSE, looked nice enough. But I can't get my external hd to work (tried force mount) and the banshee doesn't do anything like playing video. Since that is one of the two main purposes of this notebook, I need to get that to work. Tried downloading VLC player, but that only works with SuSE 11.1 upwards. So I downloaded a SuSE 11.3 and burned the iso. But surprise, no way the notebook would boot from cd. Same with the XP cd (considered setting up a dual boot). And no, I can't get to BIOS to reset to default, either. So I can basically do nothing else than going online with this thing and that's not enough for me (gamer in withdrawal, yikes!). I need at least to get to my firefox profile on the external hd and be able to watch video. Can somebody please help me? I think at this point I'd prefer to install XP and MAYBE the SuSE 11.3 after that. I'm not a native speaker, so please speak plainly, thanks. :) Edit: if this is impossible, could someone please help me with the external hd mount and video playback? Edit: Found out how to boot from cd by now. But still no XP, because I get bluescreen after bluescreen while setup is loading files. I guess it's the missing SATA drivers...
