• Using robocopy and excluding multiple directories

  - by GorrillaMcD

  I'm trying to copy some directories from a server before I restore from backup (my latest backup was corrupt, so I have to use an older one :( ). I'm in the Windows Recovery Environment and have access to the server's file system G:\ and my backup media C:\. But, since I'm more familiar with Linux, I'm having a bit of trouble with the command line in Windows, specifically robocopy. I want to copy multiple directories (maintaining the same directory structure) from G:\ to C:\ while excluding others (namely, the Windows and Program Files folders). I can't figure out the syntax for the /XD option. I was hoping to do something like: robocopy G: C:\backup /CREATE /XD "dir1","dir2", ...

• Using SSH, transfer webURL to remote machine

  - by AlanTuring

  Hi so i was doing some research in the library so i could use some pictures later on my Desktop computer in my room. I have space on my Lab account which i usually SSH into, and i was wondering if URL's can be directly transferred over to a remote machine and saved on the hard disk. I was thinking something like this: scp http://click.si.edu/images/truncatedurl.jpg /home3/etc.../filename.jpg is this possible? Thanks in advance.

• allow spoofing when using tun

  - by Johnny

  I have a working openvpn setup with a server and a number of clients. How would i go around allowing IP spoofing through the openvpn server? (to demonstrate security concepts)? A normal ping from client to server goes through all right: root@client: hping3 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes len=40 ip=10.8.0.1 ttl=64 DF id=0 sport=0 flags=RA seq=0 win=0 rtt=124.7 ms root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes 10:17:51.734167 IP 10.8.0.6.2146 > 10.8.0.1.0: Flags [], win 512, length 0 But when spoofing a packet, it does not arrive at the openvpn server: root@client: hping3 -a 10.0.8.120 10.8.0.1 HPING 10.8.0.1 (tun0 10.8.0.1): NO FLAGS are set, 40 headers + 0 data bytes root@server:/etc/openvpn# tcpdump -n -i tun0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tun0, link-type RAW (Raw IP), capture size 65535 bytes My current config files server.conf local X.Y.Z.P port 80 proto tcp dev tun ca ca.crt cert server.crt key server.key # This file should be kept secret dh dh1024.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1 bypass-dhcp" keepalive 10 120 comp-lzo persist-key persist-tun persist-local-ip status openvpn-status.log verb 3 client.conf client dev tun proto tcp remote MYHOST..amazonaws.com 80 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3

• How to update OpenSSL using Putty and yum command

  - by JM4

  I am so new to updating server technologies it is unbelievable but we are trying to become PCI Compliant and have to update some of our server technologies. One in particular is OpenSSL. We are currently running arch i686 0.9.8e but we have to upgrade to ATLEAST 0.9.8g. When I run a yum update command, there are no updates available. If I run "yum info openssl" it says available packages are: arch i386 0.9.8e but the only difference is smaller file size. I am running the following repositories: Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: mirrors.netdna.com * atomic: www6.atomicorp.com * base: mirrors.igsobe.com * extras: mirror.vcu.edu * updates: mirror.vcu.edu any help out there?

• Using Quest AD cmdlets in an imported session

  - by ASTX813

  We are trying to use remote Powershell on our Exchange system: $rs = New-PSSession -ConnectionUri <uri> -ConfigurationName Microsoft.Exchange -Authentication Basic -Credential <username> -AllowRedirection Import-PSSession $rs After these commands, we can run Exchange cmdlets and all is well. However, we're unable to run any Quest Active Directory cmdlets. Yes, Quest is installed on the remote (as well as our local machines), and yes we are able to run those commands when running Powershell locally on the server. I tried -AllowClobber, but that didn't have an effect. Is there a way to get access to QAD?

• ADFS 2.0 Server Prompts For Credentials When Using FQDN

  - by ncaudill

  We have an ADFS test enviroment set up, but we are running into issues with login prompts. If we browse to ADFS from Domain A we get a token sucessfully from ADFS, however when we browse from Domain B we are getting prompted for credentials. Domain A trusts Domain B but Domain B does not trust Domain A. The weird thing is, if we replace the full domain name with the server's IP address we can sucessfully get through from both domains. I feel like this should be a really simple solution, but we're stumped.

• Using rspec to check creation of template

• Revamping an old and unstable office IT-solution using Windows Server and OpenVPN

  - by cmbrnt

  I've been given the cumbersome task to totally redo the IT-infrastructure for a customer's office. They are currently running Windows XP all over, with one computer acting as a file server with no control over which users have access to which files, and so on. To top it off, this file server also functions as a workstation, which means it gets rebooted every time the user notices some sluggish behavior or experiences problems with flash games. To say the least, this isn't working for them. Now - I've got a very slim budget, but I need to set up a new server, and I wish to run Windows Server 2008 on it. I also need the ability to access the network remotely via VPN. Would it be a good idea to install VMware ESXi 4.1 onto the new server, and then run Windows Server 2008 as well as a separate Debian install for openvpn on it? I don't like the Domain Controller for the future AD to also run a VPN-server, because of stability issues when something goes to hell with either of them. There will be no redundancy though. However, I'm not sure if there is something to gain by installing a VPN solution on the Windows Server itself, when it comes to accessing file shares on the network via VPN. I don't know how to enable users logging in via the VPN to access the remote files, since they will be accessing the network from their own home computers (which is indeed a really bad idea, but this is what I've got to work with). They won't be logged in to the windows Domain, but rather their home workgroups. I need to be able to grant access to files in certain directories based on the logged in AD-user, but every computer won't necessarily be configured to log into the domain. I'm not sure how to explain this in a good way, but I'd be happy to clarify if somethings not clear. Any help would be great, because I've got a feeling that I can't do this without introducing a bunch of costly new rules when it comes to their IT-solution. I'd rather leave that untouched and go on my merry way to the next assignment.

• Windows 7 using llt for ipv6

  - by Seoman

  The question asked below is based on the specific implementations of the Os not the RFC. Looking on a way to be able to assign a fixed ip address to a host, before it boots I found that Centos 6 works fine with no modifications and Windows 7 does not work at all. As defined in enter link description here exists 3 valid ways of generate a DUID: 1 Link-layer address plus time 2 Vendor-assigned unique ID based on Enterprise Number 3 Link-layer address Looking at the centos, that works fine, I can see the following autogenerated DUID: option dhcp6.client-id 0:1:0:1:19:60:25:f1:52:54:0:6b:b9:9e; and the MAC address for this host is: ifconfig eth1 | grep HWaddr eth1 Link encap:Ethernet HWaddr 52:54:00:6B:B9:9E As you can see, the DUID containts the MAC address. I can assign a fixed ip address to this host by including an entry on my dhcp server similar to: host vm { hardware ethernet 52:54:00:6B:B9:9E; fixed-address6 2001:db8:0:1::200; if packet(0,1) = 1 { log(debug,"VM Request match!"); } } And the Centos 6 gets his ip. On the windows side, I faced a common problem explained on this other link enter link description here As summary, Win7 uses the option 2 of the DUID generation or a variation of this one. On the link explains how to move it to a llt (link layer + time) but is not working fine. If I modify the DUID to one that looks like the one generated on Centos (but with the right MAC) it works as expected. Question 1 How Can I change the DUID generation for Windows 7 to be based on MAC as Centos 6 does? Thanks

• how do I create a bidirectional bridge using iptables

  - by Kolzoi

  Setup: I have a samsung LCD TV that is connected via eth0 to a T41 Thinkpad running Ubuntu 10.10 which is wirelessly connected to the home router. I am trying to get Samsung's remote control app working on my iPad but the app won't allow me to put in an ip address and only discovers the tv if it's on the same subnet as the iPad (lame). So I need the laptop to route packets from eth0 to the wireless interface (wlan0), and I need about 3 ports on the wlan0 interface to be forwarded to the samsung tv. Hopefully all this makes sense. I've been messing around with iptables and samsung is now able to access internet via laptop wireless, but mapping from wlan0 back to the samsung tv is eluding me.

• Can't connect printer wirelessly to linksys wrt54g using WPS

  - by Mark J Seger

  I've already blown over 1/2 day on this. I keep checking and rechecking my router settings and they agree with what the documentation says for my brand new HP4620 printer. Supposedly I just tell the router to listen for connections and tell the printer to connect. It fails every time! Further, I have also read some opinions that when things are not configured correctly the linksys will disable WPS and it looks like that's happening as well. Further, it's causing other wireless devices in my house to lose there connectivity until I re-enable WPA networking on the router. Has anyone been here before? This is driving me crazy... -mark

• meeting availability using iPhone/iOS calendars

  - by Jaymie

  Our management team all use iPhones with the built-in iOS calendar app. We're looking into getting Microsoft Exchange for everyone here, but that'll take us some weeks to plan and roll-out across the enterprise. In the meantime, I need to provide something so group meeting availability can be determined from those calendars. Google Calendar would be ideal ("find a time") if I could find a way to link to/export the iCloud calendars, but Apple don't seem to want to do that. I could ask the management team to recreate their events for the next few weeks in individual Google Calendars, but they won't want to do that and it's wasteful rekeying of data. Any suggestions you can provide will be gratefully received.

• Unable to mount Amazon Public Dataset using ec2-create-volume

  - by the0ther

  I am trying to use a Public Dataset with the snapshot id of snap-­e1608d88. I am looking at these instructions, but they do not seem to help. The first suggestion there says I should click on Volumes and create a new volume, set it's size and availability zone, as well as specifying the snapshot id. The problem is, snapshot id is a dropdown, not a text field, and there are over 100 options in the dropdown. Next I installed the ec2 command line tools and tried to run the ec2-create-volume command. For my first attempt I tried ec2-create-volume --snapshot snap-­e1608d88 --availability-zone us-east-1 but that gave output indicating I need to provide a certificate with the --cert switch. Which certficate exactly? I tried my SSH cert at ~/.ssh/id_rsa. No dice. I got the following Java error: "org.codehaus.xfire.fault.XFireFault: General security error;"

• apt: how to search using package tags?

  - by depesz

  Some (most?) packages in Debian, have tags. For example: =# apt-cache show squirrelmail | perl -lne 'print if /^Tag:/.../^\S/' Tag: implemented-in::php, interface::web, mail::imap, mail::smtp, mail::user-agent, network::server, protocol::http, protocol::imap, protocol::smtp, role::program, scope::application, use::browsing, use::editing, use::searching, use::transmission, use::viewing, web::TODO, web::application, works-with::mail Section: web But, I can't find a way, to list all packages with given tag. Is it possible?

• Using rsyslog to create different log files for different processes

  - by user80203

  Scenario: I am running a cluster of machines. Each machine runs various python programs with a unique (across the cluster), but dynamically set, ID. Right now, they are all logging locally. So, I might have logs that look like: process_5.log process_6.log for processes that had ID's 5 and 6. Another machine may have: process_20.log process_25.log I wish to forward these logs to a logserver running rsyslogd. Python's logging facility has a nice syslog handler, so I understand how I could connect to the remote server. What I haven't figured out is how to use templating/DynFile to maintain log separation. e.g. on the logserver, I will want to see: process_5.log process_6.log process_20.log process_25.log which correspond to the logs of the same name on the sending machine. Is there a way to pull this off with rsyslogd templating?

• Windows IPSec computer authentication using *user* account?

  - by Tim Brigham

  For some reason every once in a while it happens that my IPSec authentication is from a user account to a computer account, not computer to computer. How can I fix it? Sometimes - notably when I try to add a new workstation through ePO but it's happened other times as well I'm getting strange behavior from my Windows Advanced Firewall IPSec. This causes the authentication to be invalid (as the group memberships, etc all assume computer accounts). I have no idea why this is happening or how to fix it but the IDs to match up between servers (the opposite server in my second example has remote ID timb).

• Using the internet connection of a Remote Desktop

  - by hattenn

  I want to use the internet connection of the servers at my university. I have a remote desktop account, and I have tried setting up VPN, but all VPN or proxy server software I could think of was blocked. Windows' built in VPN is blocked too. When I go to "Change Adapter Settings" and click on "File-New Incoming Connection", it says "Access denied." What would your suggestion be to use the internet connection of the remote desktop?

• Transferring to a SSD using Windows Explorer?

  - by Nick

  I've just bought a new SSD (regretting this already) which I want to make my primary hard drive on my new computer. It's a fresh Windows 8 install, so I'm wondering if I can just copy the entire contents of C: onto my new SSD drive, or will I need to copy other things too such as boot records? I don't have a CD drive unfortunately (I removed it to put in the SSD - it's a very small HTPC) and I don't have any USB stick to make a bootable copy of Clonezilla or similar. UPDATE: I have decided to re-install Windows 8 from scratch onto the SSD, the problem is obtaining the serial key that is embedded into the BIOS. I actually have a spare, unused product key from my desktop I'm writing on now, but I'd rather not use that when I already have a valid key in my new HTPC :( Thanks :)

• Using pivot tables to group transactions

  I have my bank account statement and what I would like to do is group the descriptions of the transactions together with their debit or credit and sum their total. I could then see that, e.g., for ebay.com my total debit was $2000, etc. Description Debit Credit A 1 B 1 A 1 B 1 C 1 D 1 A 1 What I want to do is use a pivot table Description Debit Credit A 3 B 2 C 1 D 1 I am no able to do that, as I can't group the description and have additional debit and credit columns -- I get them all in rows with blanks.

• Apache Key: Which is it using?

  - by quindraco

  I'm running an Apache server on Ubuntu. When I restart it, it asks me for a pass phrase; here's what the dialog looks like: Apache/2.2.16 mod_ssl/2.2.16 (Pass Phrase Dialog) Some of your private key files are encrypted for security reasons. In order to read them you have to provide the pass phrases. Server 127.0.0.1:443 (RSA) Enter pass phrase: I've already worked out how to remove the pass phrase from the key file in question, but I can't find any information anywhere on how to determine which key file Apache is complaining about in the above dialog. I have dozens of key files on the server in question, although I don't know which ones are in active use (all I did is 'locate .pem' and ignore the false positives). Does anyone know how to track down which pem file I need to remove the passphrase from?
