  • Update multiple Windows 8 to 8.1

    - by muhan
    My office has multiple Windows 8 Machines and slow internet. Is there a place online I can download the 8.1 upgrade from home on my fast internet so I can do a network or usb install at the office? I don't want to have to download 3GB+ of updates on each and every machine through the Windows store over our slow internet connection. The Windows 8 PC's in question are OEM Windows 8 Home, upgraded to Windows 8 Pro via the online Pro pack upgrade.

  • Are there disadvantages to using Outlook's Cached Exchange Mode?

    - by Roee Adler
    Since I found out about Outlook's "Cached Exchange Mode" I've been using it, and I also set it up on every PC I come across. I think it's a great feature that improves the efficiency of of every Outlook user, and I don't understand why it's not ON by default. My question is - are there any disadvantages to using Cached Exchange Mode? (Besides the obvious fact that it consumes a bit more space, which I don't see as a big issue nowadays)

  • Finding latest successful logins and failed attempts to a CentOS server

    - by ahmad
    I'm looking for a log file or any service to report the latest login attempts which have failed due to username/password miss match. Is there such utility available for CentOS? (built-in is preferred) My second question, and more generally, I need a log file of penetration attempts to my server. Ideally, this log should contain all attempts including logins, httpd activities, and other conventional open ports.

  • l2tp server always 'sent [CCP ResetReq id=0x3]' when got compressed data request

  • MSTSC RDP over the public internet

    - by stuart Brand
    My first question so please be gentle :) I have a client who is insisting that they have to let their third party vendor support access to there server directly from the internet via RDP. Our policy does not allow direct access to the infrastructure from outside of the data centre for administration except from an approved VPN connection and then virtual desktop there on to the servers. I am now in the situation where I must give good reasons why it is dangerous to use RDP over the public internet. any help would be appreciated Thanks in advance Stuart

  • Live overclocking on Windows

    - by Cyclone
    I saw this question and just had to ask. How can I do this on my own PC, where do I find this software if it exists for your computer and what can I do? I never considered overclocking before because I know myself and I know I'd mess up my hardware in some stupid accident or mistake, but if I can just do it through software it'd be nice to give it a shot. It's an Inspiron 1520 laptop, and I'd be happy to provide any other information you need to assist me in this.

  • Redundant Connection Issue

    - by Adam
    I'm trying to set up a redundant connection for our web hosting servers. I have a BGP-capable router connecting two lines from two separate ISP's, one fiber (primary), one DSL (failover). I've already confirmed that I can push routes into the DSL ISP's system, so long as they aren't malicious. My question is, what do I need to do on the fiber side to make those IP's routable through the DSL? Is there something I'm missing?

  • Skyrim: Heavy Performance Issues after a couple of location changes

    - by Derija
    Okay, I've tried different solutions: ENB Series, removing certain mods, checking my FPS Rate, monitoring my resources, .ini tweaks. It's all just fine, I don't see what I'm missing. A couple of days ago, I bought Skyrim. Before I bought the game, I admit I had a pirated copy because my girlfriend actually wanted to buy me the game as a present, then said she didn't have enough money. Sick of waiting, I decided to buy the game by myself. The ridiculous part is, it worked better cracked than it does now uncracked. As the title suggests, after entering and leaving houses a couple of times, my performance obviously drops extremely. My build is just fine, Intel i5 quad core processor, NVIDIA GTX 560 Ti from Gigabyte, actually stock-OC, but manually downclocked to usual settings using appropriate Gigabyte software. This fixed the CTD issues I had before with both Skyrim and BF3. I have 4GB RAM. A website about Game Tweaks suggested that my HDD may be too slow. A screenshot of a Windows Performance Index sample with the subscription "This is likely to cause issues" showed the HDD with a performance index of 5.9, the exact same mine has, so I was playing with the thought to purchase an SSD instead, load games onto it that really need it like Skyrim, and hope it'd do the trick. Unfortunately, SSDs are likewise expensive, compared to "normal" HDDs... I'm really getting desperate about it. My save is gone because the patches made it impossible to load saves of the unpatched version and I already saved more than 80 times despite being only level 8, just because every time I interact with a door leading me to another location I'm scared the game will drop again. I can't even play for 30 mins straight anymore, it's just no fun at all. I've researched for a couple of days before I decided to post my question here. Any help is appreciated, I don't want to regret having bought the game... Since it actually is the best game I've played possibly for ever. Sincerely. P.S.: I don't think it's necessary to say, but still, of course I'm playing on PC. P.P.S.: After monitoring both my PC resources including CPU usage and HDD usage as well as the GPU usage, I don't see any changes even after the said event. P.P.P.S.: Original question posted here where I've been advised to ask here.

  • LDAP installed, running, but can't connect remotely [Ubuntu 10.10]

    - by Casey Jordan
    Hi all, I installed LDAP on my ubuntu 10.10 system, using the tutorial found here: https://help.ubuntu.com/10.10/serverguide/C/openldap-server.html Everything seems to be working well, when logged into the server via ssh I can run commands like: > ldapsearch -xLLL -b "dc=easydita,dc=com" uid=john sn givenName cn dn: uid=john,ou=people,dc=easydita,dc=com sn: Doe givenName: John cn: John Doe So I think that's a good sign that things are working well. However I have had zero luck connecting to the server remotely via GUI tools or command line. I have tied JXplorer, and LDAP administration tool. Running commands like this: > ldapsearch -xLLL -W -H ldap://ice.rit.edu -d1 "dc=easydita,dc=com" ldap_url_parse_ext(ldap://ice.rit.edu) ldap_create ldap_url_parse_ext(ldap://ice.rit.edu:389/??base) Enter LDAP Password: ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP ice.rit.edu:389 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 127.0.0.1:389 ldap_pvt_connect: fd: 3 tm: -1 async: 0 ldap_open_defconn: successful ldap_send_server_request ber_scanf fmt ({it) ber: ber_scanf fmt ({i) ber: ber_flush2: 34 bytes to sd 3 ldap_result ld 0xb8940170 msgid 1 wait4msg ld 0xb8940170 msgid 1 (infinite timeout) wait4msg continue ld 0xb8940170 msgid 1 all 1 ** ld 0xb8940170 Connections: * host: ice.rit.edu port: 389 (default) refcnt: 2 status: Connected last used: Thu Mar 17 19:42:29 2011 ** ld 0xb8940170 Outstanding Requests: * msgid 1, origid 1, status InProgress outstanding referrals 0, parent count 0 ld 0xb8940170 request count 1 (abandoned 0) ** ld 0xb8940170 Response Queue: Empty ld 0xb8940170 response count 0 ldap_chkResponseList ld 0xb8940170 msgid 1 all 1 ldap_chkResponseList returns ld 0xb8940170 NULL ldap_int_select read1msg: ld 0xb8940170 msgid 1 all 1 ber_get_next ber_get_next: tag 0x30 len 16 contents: read1msg: ld 0xb8940170 msgid 1 message type bind ber_scanf fmt ({eAA) ber: read1msg: ld 0xb8940170 0 new referrals read1msg: mark request completed, ld 0xb8940170 msgid 1 request done: ld 0xb8940170 msgid 1 res_errno: 49, res_error: <>, res_matched: <> ldap_free_request (origid 1, msgid 1) ldap_parse_result ber_scanf fmt ({iAA) ber: ber_scanf fmt (}) ber: ldap_msgfree ldap_err2string ldap_bind: Invalid credentials (49) I am pretty sure that I set up the admin password correctly, but the tutorial was not very specific about that.

  • Forefront UAG vs. Server 2012 Direct Access

    - by Matt Bear
    So I'm working on bringing my company into the 21'st century, with virtual servers, active directory, ADFS, SSO etc. Its a huuuuge project, with a future goal of ISO 27001 cerification. The current question is, does the Direct Access role offered by Server 2012 perform the same role as Forefront Unified Access Gateway 2010 does? I'm sure there are many differences, but my primary concerns are Sharepoint publishing, ADFS proxy, reverse proxy, remote connection, and o365 syncronization.

I used debootstrap but still it is 150M large.

  • Where to get laptop replacement parts?

    - by wai
    I am sure some of us have older laptops that still works but just one or two parts started not working very well. However, to send it back to the manufacturer for repair might not be worth the money (as some of them even charge consultation fees just to have it checked) as these old laptops are most probably well beyond warranty. Replacing these one or two parts could give your laptop a new lease of life. For example, I have a Dell Inspiron 640m which the fan recently failed. Everything else still works. I know enough to open up the laptop (after reading the service manual) and put it back together again, hence a replacement fan could save it. However, finding these parts turned out to be difficult. I guess I wouldn't be able to get it from Dell since I have been searching around the Dell forums and concluded if I were going to get Dell to at least talk to me, I would have to pay some money (since my warranty expired). I found this online:- http://www.parts-people.com/index.php?action=item&id=3725 However, as I don't live in the United States, shipping alone would cost me 3 times more than the part in question. In addition, if there's a problem, it would be difficult because I probably would have to mail the parts back (costing more money). One of my friend spilled water on her Macbook, she sent it back to Apple and they told her the cost of repairing it exceeds that of buying a new Macbook. They probably have to change everything except the LCD screen. I opened it up and found that most of the parts are still working, only the RAM had fried. Replaced it and it's working again. For some time before discovering only the RAM fried, I was toying with the idea of replacing the logic board myself but looks like I didn't have to. =) Now I know there's a site for Macbooks used replacement parts:- http://www.ifixit.com/ The question is, does anyone know where to get replacement parts at their own locality? It might benefit the community as a whole. Someone might know a local computer store that sells precisely just the things we needed (for now, I hope to find a shop that sells just the fan). If you own a laptop which you had an easy experience finding the replacement parts, do post that as well. PS: I wish laptop manufacturers have outlets where they sell these replacement parts (or at least let you place an order).

  • How to check wifi networking standard of current connection

    - by yzfr1
    Both my router and my wireless networking card support the standards 802.11a/b/g/n but as I'm only getting speeds around 30-40 Mbit/s I suspect that it's the g standard being used instead of n. Now, I'd like to verify this somehow, so my question is: Is there a way (like a network diagnistics tool or the like) to find out which standard is currently used in the communication between computer and router?

  • How to reset KDE System Monitor (KSysGuard)

    - by Deltik
    Something went wrong while I was attempting to restore a backup, and KDE System Guard ceased to display properly. This is the correct display (command running from root: kdesudo ksysguard): This is the incorrect display (command: ksysguard): Here in the incorrect display, the menu bar is missing, and the tab "Process Table" is unclickable. I have already tried to remove the directory ~/.kde/share/apps/ksysguard/ but to no avail. My question: How do I restore KSysGuard back to factory defaults/normal functionality?

  • server will not reply (syn -ack)

    - by Brent
    I like to use the following commands to manage 'TIME_WAIT', in the hope to free up resources. echo 20 > /proc/sys/net/ipv4/tcp_fin_timeout sysctl -w net.ipv4.tcp_tw_reuse=1 sysctl -w net.ipv4.tcp_tw_recycle=1 I found something interesting while doing a tcpdump. Sometimes if a client makes a connection (syn), the server will not reply (syn -ack). My question is, could it be because of the top three commands.
