• Web browsing over SSH

  - by Alex Marshall

  Hello, I have something of a difficult situation : our company has a webserver in a remote data center that's, at the moment, only accessible by SSH and the firewall is not easily modifiable because the techs at the data center are unreliable and unreachable lately (not my choice of data center, and switching is not an option at the moment). Are there any browsers or plugins out there that will let me browse over an SSH connection ? I can browse with links and lynx on the SSH command line, but that doesn't give me access to various functionality I need, and it's too hard to find things in the web application running on a Tomcat server on the box that I need access to. Does anybody have any suggestions ? We're already working on getting direct access to the web application by having the firewall opened up, but I need something better in the mean time.

• after upgrade to outlook 2013 Contacts have the default picture in reading pane

  - by Juan Zamudio

  I'm using Windows 8 on a domain (using a domain account not a Microsoft account) connecting to Exchange, all my Contacts were outlook contacts with pictures and other data, I could see the picture of the contact in the reading pane and people pane while using Outlook 2010. After the upgrade to Outlook 2013 I can see my outlook contacts but it appears that they are unavailable in the reading pane because all i can see is the default picture (the default picture picture is also visible in the notifications). If I put the mouse over the name of the people while in the reading pane all I can see is the card with the default info (the only data is that the contact is available in the next 8 hours), if i compose a new message and hover the name of the contact i can see the card with all the data (picture, company, etc.). Is this the default behavior in Outlook 2013 if you are in a domain and not connected to any service or there is a way to show the picture of my contacts in every part of outlook?

• Recommended RAM and disc space for Oracle 11g on Windows

  - by Álvaro G. Vicario

  I need to provide the recommended amount of RAM and disc space (divided in two partitions) so the customer can create an appropriate virtual machine to run Oracle. All I could find in the documentation was a brief listing with minimum RAM and typical/advanced install types. The virtual machine will run latest Oracle Standard Edition One (11g release 2 so far) under Windows Server 2008 x64 and will host a reasonably low traffic web application. How much RAM and disc must I ask for in order to be safe? (Feel free to ask for further details if I've omitted something relevant.) Update: Rough estimations: Database size: 10 MB after installation Growth rate: +3MB per day on average Size of database 'active' data: (not sure of what this means, there's not actual archive so I guess all data is current) Amount of data written per second in peak hours: a few KB Number of client sessions: 3 or 4 at most Frequency and response size of most heavy requests: some reports make heavy table JOINS that need up to 20 seconds to complete but they won't return more than a few thousand rows with plain text. The app also handles BLOBs (typical size from 50KB to 200KB)

• SSL certificate: unable to get local issuer certificate

  - by celwell

  I'm running Debian (Lenny). When I run this: curl --ssl https://www.google.com I get this error: curl: (60) SSL certificate problem: unable to get local issuer certificate More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

• Passing a file with multiple patterns to grep

  - by Michael Goldshteyn

  Let's say we have two files. match.txt: A file containing patterns to match: fed ghi tsr qpo data.txt: A file containing lines of text: abc fed ghi jkl mno pqr stu vwx zyx wvu tsr qpo Now, I want to issue a grep command that should return the first and third line from data.txt: abc fed ghi jkl zyx wvu tsr qpo ... because each of these two lines match one of the patterns in match.txt. I have tried: grep -F -f match.txt data.txt but that returns no results. grep info: GNU grep 2.6.3 (cygwin) OS info: Windows 2008 R2 Update: It seems, that grep is confused by the space in the search pattern lines, but with the -F flag, it should be treating each line in match.txt as an individual match pattern.

• Need IPSec help on Windows 2003

  - by user37456

  Hey guys, I am trying to configure IPSec between a web and app server in our environment. I want all traffic between these two servers to use IPsec and be encrypted. These servers are on the same domain so i am currently using Kerebos for security, I have also tried pre-defined keys and nothing changed. When I try and ping between the servers I get "Negotiating IP Security" everytime. I have also confirmed that when I change "Require Security" to "Permit" everything works so IPSec is working, I believe its something with my security setup. Under the security tab both servers have the default 3DES keys first and then DES keys. I have also specified tunnel endpoints (the alternate server's IP). What am I missing? Thanks for any help..

• Calculate geometric mean in Excel

  - by Libby

  I have some email network data in Excel as a edgelist meaning I have columns Vertex1, Vertex2, and then N columns of properties of that edge like how many emails were sent from one person to another. For each row in the data, Vertex1 is the source of a message, and Vertex2 is the target, so edges are directed. Here's some sample data Vertex1 Vertex2 nMessages Bob Cindy 12 Cindy Bob 3 Bob Mike 11 Cindy Mike 1 I'm trying to calculate a geometric mean of the form gm = sqrt[(# of edges ij)*(# of edges ji)] So gm for Bob and Cindy is gm = sqrt[(messages from Bob to Cindy)*(messages from Cindy to Bob)] or sqrt(12*3) = 6. Is there a way to make that a formula in Excel?

• SSL FTP fails on Windows 7 but not Windows XP clients

  - by Andrew Neely

  We currently use a free SSL-FTP client called Move-It-Freely to transmit data from a custom data entry program at over forty facilities scattered around the state to our central server. Under XP, it works flawlessly. Some facilities have upgraded to Windows 7. On these machines, uploads (transfers to us) work, downloads (transfers from us to them) fail. Replacing the Windows 7 machine with an XP machine solves the problem. We have also verified that the network firewall settings have not changed. This problem persists even if Windows firewall is not running. We were able to remote into one of the Windows 7 machines to verify that the Windows firewall was indeed turned off. We cannot replicate the problem on our own Windows 7 machines, and are at a loss of how to fix this feature for our customers. The data contain health-related information, and needs to be encrypted (hence SSL-FTP.) Despite hours spent on Google, we cannot find a solution.

• NetFlow Storage Calculator

  - by javano

  I am planning to deploy a NetFlow server (using NfSen/NfDump) for harvesting data from Cisco devices; Are there standard calculations or guidelines I can use to calculate my server requirements, specifically I need to plan for storage. Is there a way of knowing how much data I will collect per day for example, given N flows? Lets say one device has 10k flows per day, this is typically XYZ MBs, so I can scale this up? If not, how many flows are you guys and girls recording per day, and how much data is this generating? Hopefully we can generate an estimate from everyone else's figures! P.S. If it makes a difference, I'll be collecting from <= 50 devices max (non more than 50Mbps each).

• Automatic LaTex document generation from Excel spreadsheet

  - by Bowler

  I have some data in an excel file from which I have to generate a report. I repeat this task fairly regularly and am looking to automate it. I have a LaTeX project into which I usually just copy data by hand, export the necessary worksheets as pdfs and add them to my LaTeX project and compile with pdflatex. It has occured to me that there must be a way to automate this process. Is there an efficient way to export the data from excel and into a LaTeX project, possibly a vba script in excel could run the process? Also, it doesn't have to be LaTeX, I'm not all that experienced with MS office's more advanced features is there some way akin to a mail merge that I could achieve this with? In some ways this might be better in case I have to pass the work on to someone who doesn't know LaTeX. Thanks.

• migrate SharePoint to SBS Server

  - by Eric Lorson

  We have a SharePoint 2003 server and we need to migrate that data to SharePoint 2011 on a SBS server. We cannot use the migration tool because one of the servers is SBS and the other is not. We exported the SharePoint data from the old system, but the import to the SBS SharePoint is failing with very little info on why. I think that there is a schema conflict, but I am not that familiar with SBS and I am not finding the error in the Windows logs. Has anyone had to migrate data from non-SBS system to an SBS system? Or can anyone help me figure out where to look for more info on what is going on?

• Use apt-get source on a debian repo without using /etc/apt/source.list

  - by Erwan Queffélec

  I'm trying to use apt-get source as a regular user on a debian squeeze system. I want to retrieve the sources for cyrus-imapd-2.4 from the testing/wheezy repository. apt-get source works without root privileges; however, it seems there is no way to get apt-get to fetch anything from a repository that is not in /etc/apt/sources.list. Is there any command line option, alternate sources.list file, environment variable that will get apt to work with a custom repository ? I do have root access so I could change the /etc/apt/sources.list, however I really do not want to do that for a number of reason.

• pnp4nagios does not generate perfdata

  - by gonvaled

  I am running nagios2, pnp4nagios-0.6.16 and php 5.2.4-2ubuntu5.19. In my setup, pnp4nagios is correctly generating perfdata, which can be seen via the web interface in graphical form for lots of services. The perfdata directory contains entries of the kind: /usr/local/pnp4nagios/var/perfdata/zeus/Disk_Space_Home.rrd /usr/local/pnp4nagios/var/perfdata/zeus/Disk_Space_Home.xml I have activated performance data for a new nagios service: define serviceextinfo { host_name zeus service_description 450average action_url /pnp4nagios/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$ } This service is generating monitoring data in the format: status_info|perf_data as required for performance gathering. But somehow the performance data related to this service is not being collected by pnp4nagios (no related entries in /usr/local/pnp4nagios/var/perfdata) Are there any pnp4nagios scripts or settings which I could use to debug this?

• How to sync a folder on a remote computer to a server on a domain

  - by Pierre-Alain Vigeant

  We have a small remote office that often share data with us. I learned that the data is shared as a email attachment, but that obviously leads to versioning hell and overriding. I am looking for a way for then to synchronize a folder directly on our main office domain controller. I personally use LiveMesh, but I would like a tool that is synchronized to our server directly without a 3rd party hosting the data, since we already have an online backup service taking care of the offsite backup. What enterprise class tool would let us synchronize a folder from a remote computer that is out of our domain, into our the file server of our domain? The synchronization has to be two-way, e.g.: Someone from the remote office will create an invoice. Someone from our office will review it and make modification to it. The remote office need to see the change. Our server is on Windows 2003.

• Can I mark a folder as mountpoint-only?

  - by Collin

  I have a folder ~/nas which I usually use sshfs to mount a network drive on. Today, I didn't realize the share hadn't been mounted yet, and copied some data into it. It took me a bit to realize that I'd just copied data into my own local drive rather than the network share. Is there some way to mark in the system that this folder is supposed to be a mount point, and to not let anyone copy data into it? I tried the permissions solution here: How to only allow a program to write to a directory if it is mounted?, but if I don't have write access I also can't mount anything to it.

• Remote Desktop Services In A Virtual VMWare Environment

  - by Christopher W. Szabo

  I have a quick question regarding Microsoft Remote Desktop Services in a virtualized environment using VMWare. This environment will actually be hosted in a large data center with in a cloud that is offered. This particular data center has the ability to establish high speed point to point connections with customers via metro-ethernet who are hosted in the cloud. The result is that customers can actually host their corporate domain in the data center's cloud. Put the merits of such a configuration aside for the time being. Believe me when I say that the cloud is stable and had enough hardware behind it to rival a dedicated cabinet. My question has to do with RDS in a virtual environment, which would amount to virtual desktops hosted on a virtual server. I've read that this works without issue using Hyper-V and VMWare. But before I take the plunge I wanted to get some feedback from the community.

• Can I use the voice & SMS features of my GSM SIM through my laptop?

  - by i..

  My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

• How to select text in Pico when I don't have a carat character?

  - by Andrew Swift

  I am using Pico via Terminal/SSH on an iPad with a French bluetooth keyboard. There is no way to type the carat (^) key to select text (control-carat to start selection). The carat on the keyboard is used to type a circonflex accent (août), and only becomes active when one types a letter after pressing it. There is therefore no way to type control-^. When I do type ctrl-^ in Pico, the cursor moves to the previous line. Is there an alternate way to select text in Pico? I can't see how to use it without finding a solution.

• Fix for OpenSolaris with no gcc vs. Nexenta with no ext3

  - by Jake Wharton

  I'm attempting to migrate my server from linux to a Solaris variant during a hardware upgrade. The machine is based around an Abit AN-M2 board which has an NForce chipset. I have what seems to be a chicken-and-egg problem of sorts: OpenSolaris 2009.06 does not recognize the NIC and I cannot compile the drivers for it as it also lacks gcc. I haven't tested as to whether or not I can mount an ext3 partition yet but its moot if there is no networking. Nexenta 3.0b3 recognizes the NIC but I cannot get the ext3 drives mounted due to FSWfspart refusing to install. I do not know much about Solaris but I wager this is due to the fact that Nexenta is based around Debian as well. While I am reusing the mobo/CPU combo, I did just spent a lot of money on the other hardware around it and would very much like to get it up and running smoothly and quickly. Does anyone have any suggestions that are not: Get a new mobo/CPU Run another OS Use alternate NIC

• ODSI + weblogic = JDBC problem

I created a datasource on weblogic using the driver "Oracle thin driver 10g", the test succeed on WebLogic. (My Database is Oracle 10 10.2.0.1.0) The problem occours when I try to create the Phisical Data Service in the Oracle Workshop. I choose the following options: Data source type = Relational Data source = [THE CORRECT NAME OF THE SOURCE SET ON WEBLOGIC] Database type = ??? Aqualogic, doesn't allow me to select the database type. I guess is a problem related to the driver set on weblogic... but I ain't sure.Does someone know the nature of my problem ? Tnx

• Mounting Google Driva via WebDav directly on Google

  - by WoJ

  I would like to mount on my RPi my Google Drive using davfs2 but I did not find any direct way to do it for Google Drive. There are instructions on how to use dav-pocket to indirectly do that but these are from 2010. Google group discussions about the lack of direct WebDAV access to Google are roughly from the same time and I could not find any other way to do the mount. Has anything changed and would anyone know if Google enabled WebDAV - and if so what is the URL? An alternate synchronization system would be fine as well (rsync for instance) - I did not find any particular infos either Thank you!

• Best solution for High Availability and SSRS on SQL Server 2008 R2?

  - by Chandra

  I have 2 Physical Servers with SQL Server 2008 R2. – SQL Server 1(Active) & SQL Server 2 (Passive) Web Application is developed using .Net 4.0 Framework. I want to know the best solution to have high availability and also have SSRS for reporting. Planned solution: Mirroring for Failover, and Transaction Replication for SSRS as the mirrored database can only be used for failover scenarios. SSRS will be on the Passive server, to reduce the load on the Active server. Let me know if the solution is correct. Also suggest alternate approaches.
