• How can I get data off of a damaged thumb drive?

  - by Lord Torgamus

  A guy I work with just came by to ask me about a damaged thumb drive/USB flash drive. Apparently his son dropped it on a hard surface and it won't power up anymore. They've tried plugging it into multiple machines without success, even though each port they tried was able to power other USB devices. He knows it's not a lost cause because a local tech store is offering to recover the data for $500, but he says they're not worth that much. I figured someone on SU would have an idea about this; he doesn't care about using the drive in the future, just wants to salvage a few files that would be a pain to recreate. Is this possible without advanced equipment, and if so, how? He said he already tried the advice on the Internet about typing in different drive letters and such, but that failed because there was no power going to the drive. He also said that he opened the case up at one point, but I'm not sure what, if anything, he did inside.

• FreePBX: Asterisk in the Cloud (EC2) Audio Problems

  - by neezer

  Please pardon the newbie question, but I can't seem to figure this out. I followed the Voxilla's tut to the tee: http://voxilla.com/2009/10/15/voxill...p-by-step-1457 But in making calls, my softphones connect, yet no audio (in either direction). I know from poking around the forums that this is generally caused by two factors: NAT and audio codecs. I (being new to the arena), however, don't know which. I believe I have Asterisk and the clients restricted to just ulaw, and I also believe I have the correct ports open, and my externip set correctly (I think the Voxilla AMI does this automatically, since it's in the cloud). I'm a bit lost. I'd be happy to post whatever configuration files that might help, provided you tell me where they are on the filesystem. But like I said before, this is effectively a vanilla install of Voxilla's own FreePBX AMI. I'd appreciate any help or guidance here. Thanks!

• Time Machine Server on Fedora

  - by Conner Stephen McCabe

  I was just wondering if anyone knew how to/or knew of a good guide to setting up mac Time Machine backup server on a fedora 17 machine. I recently ran into an issue with my HDD and lost all of my data, so I don't want it to ever happen again, as it was quite traumatising, haha! I just want to be able to back all of my data up on my fedora machine from my mac, at scheduled times when I connect to my home network. If anyone could help, it would be fantastic, I searched around on google, but all of the ones I found were for older distros. Thanks guys!

• In Open Calc, how do I copy a paste cells that contain references to other workbooks?

  - by Gabriel

  I have an OpenOffice Calc sheet with cells containing formulas that refer to another file, e.g: 'file:///C:/path/to/other.xls'#$Sheet1.A1:B2. Note: When I copy the cells from one sheet to another in the same workbookt, it works as expected. When I copy this to a sheet in another workbook, the references are lost and all is left is ''#$Sheet1.A1:B2. I could copy/paste the cell's contents, but that would be fastidious, error-prone, and anyhow not a good solution. How do I keep the external references when copy-pasting from one workbook to another ?

• How to know which revision or router I do have?

  - by Rosamunda

  I´m trying to update my D-link Dir-600 router with the dd-wrt firmware. I´ve searched for it at the site and found that: Revision A1, B1 and B2 are supported, while C isn´t. Now my router has this information on the back: P/N IIR600GNA .... C1G H/W Ver: C1 F/W Ver: 3.01 So I guess the H/W Ver is the revision, and it´s C... so it´s a lost cause? Or maybe because it´s not just C but C1 I could do something with it? Thanks!

• Redundant Router and Load Balancing vs. DDoS attack

  - by colgatta

  With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?

• Is it possible to FORMAT an external hard disk that has been encrypted using Storagecrypt?

  - by Pandian John

  Basically the big problem is that about 680 GB of data from my Seagate 2 TB Ext HD is lost because I was experimenting with a software called storagecrypt. I used it a few months ago and today I tried it again but i didn't know that the old password is already set in the hard disk when I pressed the encrypt button. I forgot the password which is disappointing. Not to mention that software uses 128 bit AES encryption so there is no way iam going to recover that data. My question is that is it possible to Format my Hard disk which has been encrypted? What i mean is that is it possible to completely wipe the data just like it is newly bought so that I can use my External Hard disk?( I tried to format by right click-- Format. But the size of the disk is shown as 1 MB. Answers would be very much appreciated. Thanks.

• Windows folder encryption

  - by Razor

  My situation I know that bitlocker is meant to encrypt whole drives, but I have an hard drive that is already fully partitioned and containing data. I'd like to encrypt part of one partition, leaving the rest of the partition accessible. I would very much like to avoid programs like Norton partition magic (which resize/split partitions), because every time I used them I had problems with the data stored. Question Is there any way/builtin alternative/3rd party app that integrates with windows login to encrypt one subset of a partition? EDIT I heard horror stories about EFS, which is why I don't want to use it, unless there have been improvements on reliability with windows 8. Some highlights from that article: In fact I’ve only used EFS twice in the last ten years on my own computers and on both occasions I’ve lost files and documents. I therefore cannot recommend you ever encrypt your files with this Windows feature. Unfortunately, because of incompatibilities with some differing versions of EFS files can end up scrambled and unrecoverable.

• UTF-8 bit representation

  - by Yanick Rochon

  I'm learning about UTF-8 standards and this is what I'm learning : Definition and bytes used UTF-8 binary representation Meaning 0xxxxxxx 1 byte for 1 à 7 bits chars 110xxxxx 10xxxxxx 2 bytes for 8 à 11 bits chars 1110xxxx 10xxxxxx 10xxxxxx 3 bytes for 12 à 16 bits chars 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 4 bytes for 17 à 21 bits chars And I'm wondering, why 2 bytes UTF-8 code is not 10xxxxxx instead, thus gaining 1 bit all the way up to 22 bits with a 4 bytes UTF-8 code? The way it is right now, 64 possible values are lost (from 1000000 to 10111111). I'm not trying to argue the standards, but I'm wondering why this is so? ** EDIT ** Even, why isn't it UTF-8 binary representation Meaning 0xxxxxxx 1 byte for 1 à 7 bits chars 110xxxxx xxxxxxxx 2 bytes for 8 à 13 bits chars 1110xxxx xxxxxxxx xxxxxxxx 3 bytes for 14 à 20 bits chars 11110xxx xxxxxxxx xxxxxxxx xxxxxxxx 4 bytes for 21 à 27 bits chars ...? Thanks!

• Secure Browsing, how [closed]

  - by Jhonny Bigodes

  Possible Duplicate: How to browse safely? What's the best way to browse "suspicious" sites safely. I know Firefox used to be "the thing", but now I don't think it is (IMHO). What I'm using now is a virtual machine (with virtual box), rhat I periodically format. I heard some time ago of a project that glued the 2 together (kinda... everytime you startup the program it used a fresh machine with a fresh browser), but I lost track of them So my question is: How can I Browse the web securely ? Ps.: In in ubuntu

• SBS 2008 reinstall on new machine

  - by Jon

  We purchased a single license on Windows Small Business Server 2008 for a medical office, and soon after a power fault caused the server to overload, destroying the power supply and motherboard. I reinstalled on a new server, and have the domain up and running again, but under system properties it tells me I still need to activate windows, and that the product key currently entered is invalid for activation. I've been trying to figure out how to get in touch with Microsoft to explain the situation and get a new activation key issued without having to pay for another license which we can't afford, but the online documentation hasn't been particularly clear on the subject. Does anyone know how to do that, or if I do need the activation key to continue using SBS 2008? (It currently tells me I have 56 days left to activate) Any tips would be appreciated. I'm not strictly a computer guy and I'm feeling a little lost.

• Ethernet port sleeping on PS3 running linux

  - by Doug

  My lab has a PS3 running Ubuntu Linux 9.04 Server Edition. After a period of a few hours with no use, the Ethernet connection (eth0) seems to go to sleep, causing the connection to be lost. Pinging or trying to SSH into the machine results in no response. The fix I've been using is to access the machine locally and restart it (trying to bring eth0 down then up doesn't seem to correct it). I've tried setting up an hourly cron job that runs on the PS3 and pings another machine just to create network activity, but this doesn't seem to solve the problem either. Update: The solution was to run the above cron job much more frequently: every 10 minutes works.

• Custom string class (C++)

  - by Sanctus2099

  Hey guys. I'm trying to write my own C++ String class for educational and need purposes. The first thing is that I don't know that much about operators and that's why I want to learn them. I started writing my class but when I run it it blocks the program but does not do any crash. Take a look at the following code please before reading further: class CString { private: char* cstr; public: CString(); CString(char* str); CString(CString& str); ~CString(); operator char*(); operator const char*(); CString operator+(const CString& q)const; CString operator=(const CString& q); }; First of all I'm not so sure I declared everything right. I tried googleing about it but all the tutorials about overloading explain the basic ideea which is very simple but lack to explain how and when each thing is called. For instance in my = operator the program calls CString(CString& str); but I have no ideea why. I have also attached the cpp file below: CString::CString() { cstr=0; } CString::CString(char *str) { cstr=new char[strlen(str)]; strcpy(cstr,str); } CString::CString(CString& q) { if(this==&q) return; cstr = new char[strlen(q.cstr)+1]; strcpy(cstr,q.cstr); } CString::~CString() { if(cstr) delete[] cstr; } CString::operator char*() { return cstr; } CString::operator const char* () { return cstr; } CString CString::operator +(const CString &q) const { CString s; s.cstr = new char[strlen(cstr)+strlen(q.cstr)+1]; strcpy(s.cstr,cstr); strcat(s.cstr,q.cstr); return s; } CString CString::operator =(const CString &q) { if(this!=&q) { if(cstr) delete[] cstr; cstr = new char[strlen(q.cstr)+1]; strcpy(cstr,q.cstr); } return *this; } For testing I used a code just as simple as this CString a = CString("Hello") + CString(" World"); printf(a); I tried debugging it but at a point I get lost. First it calls the constructor 2 times for "hello" and for " world". Then it get's in the + operator which is fine. Then it calls the constructor for the empty string. After that it get's into "CString(CString& str)" and now I'm lost. Why is this happening? After this I noticed my string containing "Hello World" is in the destructor (a few times in a row). Again I'm very puzzeled. After converting again from char* to Cstring and back and forth it stops. It never get's into the = operator but neither does it go further. printf(a) is never reached. I use VisualStudio 2010 for this but it's basically just standard c++ code and thus I don't think it should make that much of a difference

• How to issue machine certificates to Android devices trying to connect to L2TP VPN (L2TP/IPsec with Certificate)?

  - by John Hendrix

  I are trying to find a way to connect Android devices to our VPN box running Windows Sever 2008. We manage to configure a couple Android devices to connect via PPTP. However, I would like to be able to connect using L2TP/IPSec with certificates instead. I've managed to export and apply the Enterprise CA's certificate on the Android phone, but are totally lost on how to issue a machine certificate to the Android phone. Is it even possible? If so, what are steps I should take to issue the machine certificate and enable the Android phone to connect via L2TP/IPsec with certificates? Thank you for your help!

• Transfer an account from a 'dead' domain

  - by PJC

  So - following from my previous question: How do I stop DFSR replication preventing a Domain Controller from advertising Domain Services?, I lost the FSMO DC, and my only other DC was in an unrecoverable state. I've created a new domain to continue my testing, but now have an issue which I suspect is relevant to any domain suffering a "catastrophe". I have user accounts and client PCs "on the old domain". (Actually 1 client PC and 3 accounts) I can still sign into the client PC as any of those users on the "dead" domain, because that is cached. There are (thankfully) no encrypted files in the "old" domain. What I would now like to do is migrate the full content (files, preferences, etc) from the "dead" domain to the new "live" domain for any/all user accounts, for the "old" PC. Is there anything out there which can assist me in doing so?

• What's the best practice for keeping track of Microsoft solution stack Hot fixes and patches?

  - by melaos

  i'm currently working on a product that is build on microsoft stacks such as sql server, entity framework, wcf, c# and biztalk server. so recently we're running into weird issues on our production servers and now we're troubleshooting this issue. we're kind of lost. so we're looking into anti virus exclusion and cumulatives updates for biztalk server. but my question now is what's the best way to keep track of all the hot fixes? do we just check for them, i.e. google it up only when we have issues? i've googled online and found that there's a microsoft baseline analyzer tool. and the other thing is microsoft blog which is updated on a weekly basis which contains all the recent hot fixes. are there a better way or best way? thanks for my ignorant question.

• Configure Postini and emailreg.org

  - by crn

  One of our companies uses Postini services as our spam filtering service. Unfortunately, the company has been tagged as a spammer and we're trying to use emailreg.org to whitelist us. Emailreg.org wants us to add a CNAME which points to their domain (emaireg.org), while Postini has us add MX records (such as domainname.s7a1.psmtp.com. Here are my questions: 1. Can adding Emaireg's CNAME cause either Postini to not work or our emails to be lost? 2. Which is order of execution (do the email go to Postini and upon their return to EmailReg or is it the other way around)? 3. Is there anything of which I should be aware when using such a setup? Thanks, in advance, for all your help!

• Windows Server 2008 R2 - Can't connect RDP over the Internet

  - by Jonathan DeMarks

  I have two networks: Domain and Public, Domain is a VPN connection and Public is the local connection to the network. This is not a domain controller or a DNS/DHCP server. I can connect via RDP from the local network (192.168.1.), from the VPN network (10.1.2.), and from the VPN network over the internet. I cannot connect from the internet (anywhere besides where the server is VPN'd) Wireshark indicates that the server is getting packets, and the audit log is indicating that the packets are being dropped. Advanced Firewall has explicit options to allow RDP, and has no deny policies. I have also tried turning Firewall off completely to no avail. I'm really lost on this one.

• routing weirdness - traceroute 'vanishes' en route

  - by The Journeyman geek

  I'm attempting to set up one of my boxes as a server (again), but i'm having some odd connection issues- the box itself connects fine to the internet, but trying to connect to my external ip address seems to result in the trace getting 'lost' partway. http://pastebin.com/HCQAGbvn - this is a traceroute from another system that's connected to another ISP - starhub is my own one, while i have another system that i have access to on singtel. I'm wondering if my ISP is messing around with routing, or is something very odd going on. As you note, the traceroute dosen't reach me, but if it helps, i use a dd-wrt router. edit: Facepalmishly, turning the firewall on my router on and off fixed it. I don't get why it dropped off at different ip addresses each time, or why the router set it self to block.. everything, or why it affected the ipv6 tunnel as well.

• Apache ProxyPass/ProxyPassReverse to IIS

  - by Dana

  We have an ASP.NET web application which is mapped to a folder on an apache hosted php site using ProxyPass.ProxyPassReverse. A couple of problems being encountered. cookies are being lost which breaks the site navigation, this can be overcome by setting the asp app as cookieless. Forms authentication is used on the ASP site, this is also broken withe the proxypass in place, suspect this is cookie related also. ASP site works ok when run from a domain/ip address. Use of a separate domain / sub-domain is not an option duew to client requirements.
