• Wireless keeps shutting off in Windows 7

  - by Nathan Adams

  I have Windows 7 Ultimate 32bit installed on a Dell Latitude XT Tablet and for the life of me I can't figure out this really weird problem. The symptom is that the Wireless will disconnect from the AP and if I tell it to scan again, it says there are no APs in the area. I do have another wireless card in the laptop and if I disable the first one and enable the second, I am able to get onto the wireless however if I want to use the first card again I have to restart. I tried enabling/disabling the device, nothing will kick start the wireless again in the first card without a restart. I even tried different drivers. So, it seems it is random but it does occur more often when there is increased network activity (ie downloading a large file). The laptop doesn't seem to be overheating. I have tried the following: Under "Change Advanced Power Settings" for the current power profile, I set the "Wireless Adapter settings" to "Maximum Performance". Under device manger, I went to the card in question, and went to the advanced tab and set the "Power Saving mode" to "MAX_PSP" Both cards I have seem to exhibit the behavior after awhile. Both models of those cards are: Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Gigabyte GN-WS30N 802.11n mini WLAN Card Has anyone have any ideas or ran into this before?

• Sever 2008 R2 Powershell Script runs manually, but not as a scheduled task

  - by Aeisor

  I have a Powershell script that runs manually using the Powershell ISE; However, when run as a scheduled task using an administrator's credentials the task does not run with the expected results. The script: $request=new-object System.Net.WebClient $request.DownloadFile("...url...", "C:\path\to\file.csv") The administrator user has Full Control of both the script and the folder it is writing to. The url exists and responds in a reasonable time (<1s). If I run the task manually the status is 0x41301 ("Currently Running") until I eventually end it. I have set the task up using both of these methods: Start a Program: C:\path\to\PS.PS1 Start a Program: C:\windows\system32\WindowsPowerShell\v1.0\powershell.exe with additional options -noninteractive -command "C:\path\to\PS.PS1" Using option 1, the task history shows it has opened an instance of notepad.exe but never terminates it. Using option 2 it completes the task but doesn't download / create the file. I have used Set-ExecutionPolicy Unrestricted as this is not a signed script. Any ideas?

• Moving Microsoft Exchange server to the private network.

  - by Alexey Shatygin

  In one of the offices, we have a 50-computers network, which had only one server machine: Windows 2003 Server Microsoft ISA Server Microsoft Exchange 2003 This server worked as a gateway (proxy server), mail server, file server, firewall and domain controller. It had two network interfaces, one for WAN (let's say 222.222.222.222) and one for LAN (192.168.1.1). I set up a Linux box to be the gateway (without a proxy), so the Linux box now has the following interfaces: 222.222.222.222 (our external IP, we removed it from the Windows machine) and 192.168.1.100 (internal IP), but we need to keep the old Windows server as a mail server and a proxy for some of our users, until we prepare another Linux machine for that, so I need the mail server on that machine to be available from the Internet. I set up iptables rules to redirect all the incoming connections on the 25th and 110th ports of our external IP to 192.168.1.1:25 and 192.168.1.1:110 and when I try to telnet our SMTP service telnet 222.222.222.222 25 I get the greetings from our windows server's (192.168.1.1) SMTP service, and that's works fine. But when I telnet POP3 service telnet 222.222.222.222 110 I only get the blank black screen and the connection seem to disappear if I press any button. I've checked the ISA rules - everything seems to be the same for 110th and 25th ports. When I telnet on 110th ports of our Windows server from our new gateway machine like this: telnet 192.168.1.1 110 I get the acces to it's POP3 service: +OK Microsoft Exchange Server 2003 POP3 server version 6.5.7638.1 (...) ready. What sould I do, to make the POP3 service available through our new gateway?

• Dosbox USB print Windows 8.1 64Bit

  - by eCronik

  Worked fine until I've upgraded to Windows 8.1 as well as made the mail programm working (had to get a windows live ID and have to type in a password now, when starting Windows). I did set the USB printer to lpt1 on the local Windows 8 computer and another XP computer via LAN to lpt2 the same way with the same printer on the Windows 8 computer. But now it doesn't work anymore from the Win8 one (where the printer is plugged via USB). Tried already deleting lpt2: on the XP one, as well as lpt1 on the Windows 8, resetted it. Not working... :-( I tried also net use lpt1: \server\printer password "\user:Ute Berger" /persistent:yes of course with the correct server and shared printer name as well as net use \server\printer "\user:Ute Berger" password /persistent:yes . This is the name displayed as a user now. But in C:\users it is named Benutzer1. Tried this one also. Nothing worked. What could be the problem here? What's strange is that when I type "net use lpt1:" on the XP, I get another error (67 - The networkname wasn't found) than trying something I didn't set up like lpt2 (2 - The system can't find the file). Could this be a possible problem as even if deleted something is left blocking on the Windows 8 computer? Please help me - I tried for hours today but all I've got was frustration... Regards Tim

• External HDD incorrectly detected as internal - how change to enable hot swap/eject?

  - by Sam

  I have win 7 x64 Home Prem. The HDD is a seagate barracuda, 7200.7 ST3120827AS. 3.5", Serial: 3ms006n6, Firmware: 3.42 (no further updates) NexStar CX External case (drivers installed). I have three drives: WD320 with OS installed WD750 data storage (internal) seagate 120 (external) - connected via esata board connected to sata on motherboard (MSI p43 neo) Tried uninstalling HDD in device manager to no effect. Also the internal WD750 is detected as an external drive and win taskbar icon allows for it to be ejected (unlike the seagate). All drives are configured - Online, Simple, Basic, NTFS, Active, Primary Partition (except c drive). The seagate was previously used as a primary disk with XP operating system so I deleted the volume and created/reformatted (not quick). HDD is no longer "Active". But did not fix problem. Background Originally, I installed win 7 with the bios set to IDE and forgot to install the chipset drivers. Then I changed win 7 to install the AHCI drivers, changed the bios to AHCI and rebooted. Win 7 loaded drivers but WD HDD gave problems/crashed. I installed chipset drivers and latest intell storage matrix software thingie (in safe mode). Everything worked fine after that except for the problem of not corrrectly detecting the external drive] I have noticed that under the driver properties (and similarly in the registry) the two drives are configured differently (e.g. in driver details property capabilities for the WD the value is set to 0000006, CM_DEVCAP_REMOVABLE & EJECTSUPPORTED - whereas the seagate shows 0000080 & CM_DEVCAP_SURPRISEREMOVALOK). Any easy way to configure things? I tried physically swapping the sata connections on the mainboard without success So far I have found that a solution to my problem might be to perform some reg changes: How do I remove the option to eject SATA drives from the Windows 7 tray icon?

• sbs-server with 2 nics and 2 connections to the internet with different providers not working as it

  - by erik-van-gorp

  We have the following configuration : A sbs-2003 server in a domain (mydomain.com) with 2 network cards, each connected to a different network (provider), with different gateways, one for web and one for mail and clients. (we do this because the bandwitdh we get from our providers is too small to handle all the mail(+spam) traffic and webservices, so we took 2 providers) DNS is as follows : www.mydomain.com 1.2.3.4 mail.mydomain.com 5.6.7.8 NIC 1(192.168.1.3) is connected to to the internet through a firewall at 192.168.1.1, having wan address 1.2.3.4 NIC 2(10.0.0.3) is connected to to the internet through a firewall at 10.0.0.1, having wan address 5.6.7.8 Both nics have their default gateway installed at their corresponding routers. Also the metrics are set equal. (i know this isn't a supported config, but it works more or less). In this configuration i can use RDP on both wan adresses, and telnet to port 25 works as well on both. The issue now is that since a few weeks , we get regular disconnections, and website hickups(timeouts), several per hour. If we set one router to a higher metric, that route no longer works. In short, I want the mails to route through NIC2 and the web through NIC1. Any better configuration (without installing a second mail server) ?

• Which revision control system for single user

  - by G. Bach

  I'm looking to set up a revision control system with me as a single user. I'd like to have access (read and write) protected using SSL, little overhead, and preferrably a simple setup. I'm looking to do this on my own server, so I don't want to use the option of registering with some professional provider of such a service (I like having direct control over my data; also, I'd like to know how to set up something like that). As far as I'm aware, what kind of project I want to subject to revision control doesn't really matter, but just for completeness' sake, I'm planning on using this for Java project, some html/css/php stuff, and in the future possibly as a synchronizing tool for small data bases (ignore that later one if it doesn't fit in with the paradigm of revision control). My questions primarily arise from the fact that I only ever used Subversion from Eclipse, so I don't have thorough knowledge of what's out there, what fits better for which needs, etc. So far I've heard of Subversion, Git, Mercurial, but I'm open to any system that's widely used and well supported. My server is running Ubuntu 11.10. Which system should I choose, what are the advantages of the respective systems, and if you know of any particularly useful ones, are there tutorials regarding the setup of the system I should choose that you could recommend?

• Windows thinks outgoing connections are incoming connections?

  - by Slayer537

  I have a rather weird issue.. I'm trying to configure Windows Firewall to block all outgoing connections to a certain app, but allow all incoming. This app is used to transfer files across a network. The reason for this type of setup is to only allow certain users (IP Address) access to the files I have, but to still allow others to see what's available. Since Windows Firewall defaults to allowing all outgoing connections, I made a rule to deny all outgoing connections that were not in the IP ranges I specified. For the incoming connections, I'd like to leave it at allow all, but at the moment it is set to only allow the connections that also have outgoing permissions set. If I blanket say allow all incoming connections, I observe that unauthorized IP Address are able to actually download files, even though their IP was blocked in the outgoing connections. To shed a little more visibility on this, I used NetLimiter to see what was going on. NetLimiter showed me that the connection was an incoming connection. Shouldn't this be an outgoing connection, as I am uploading files to them, not the other way around? Is there a way to make the connection type be correct and show up as outgoing instead of incoming?

• Microsoft Mouse and Keyboard Center - Slow response for App-specific shortcuts

  - by Darrel Hoffman

  So a few months ago, I bought a new MS mouse, and was surprised that they'd discontinued Intellipoint in favor of this Microsoft Mouse and Keyboard Center. It seems to have the same functionality underneath all the bloat, but there's a very serious drawback - when I set up application-specific functions for the extra buttons on the mouse, they work, but sometimes with a very long delay, like up to a minute or more. For example, I often set up the left side button as an "Undo" in various programs for convenience. But sometimes, when I try to use that Undo button, nothing happens, so I'm forced to use the standard Ctrl-Z or whatever. But then, a minute or so later, it suddenly remembers that I hit that button a while back, and calls the Undo unexpectedly on something entirely different. It's infuriating. No modern computer function should be this slow. It's not the software or the computer itself, because doing an Undo via Ctrl-Z or the menu still works instantly. It's very definitely a side-effect of delayed response to the mouse button. Usually after it delays the first time, it'll work quickly after that, but if you haven't used a given shortcut in several minutes, it "forgets" again and you get another inexplicably long delay. Intellipoint never had this problem, but it's not supported any more, and not compatible with the newer mice. Has anyone else noticed slow-downs with MS M&K C and app-specific shortcuts? Any ideas how to get around this? I use these shortcuts extensively in my workflow and it's just entirely unacceptable to have such a long delay in what should be a pretty basic feature.

• OpenVPN + iptables / NAT routing

  - by Mikeage

  I'm trying to set up an OpenVPN VPN, which will carry some (but not all) traffic from the clients to the internet via the OpenVPN server. My OpenVPN server has a public IP on eth0, and is using tap0 to create a local network, 192.168.2.x. I have a client which connects from local IP 192.168.1.101 and gets VPN IP 192.168.2.3. On the server, I ran: iptables -A INPUT -i tap+ -j ACCEPT iptables -A FORWARD -i tap+ -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On the client, the default remains to route via 192.168.1.1. In order to point it to 192.168.2.1 for HTTP, I ran ip rule add fwmark 0x50 table 200 ip route add table 200 default via 192.168.2.1 iptables -t mangle -A OUTPUT -j MARK -p tcp --dport 80 --set-mark 80 Now, if I try accessing a website on the client (say, wget google.com), it just hangs there. On the server, I can see $ sudo tcpdump -n -i tap0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tap0, link-type EN10MB (Ethernet), capture size 96 bytes 05:39:07.928358 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 558838 0,nop,wscale 5> 05:39:10.751921 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 559588 0,nop,wscale 5> Where 74.125.67.100 is the IP it gets for google.com . Why isn't the MASQUERADE working? More precisely, I see that the source showing up as 192.168.1.101 -- shouldn't there be something to indicate that it came from the VPN? Edit: Some routes [from the client] $ ip route show table main 192.168.2.0/24 dev tap0 proto kernel scope link src 192.168.2.4 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.101 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.1.1 dev wlan0 proto static $ ip route show table 200 default via 192.168.2.1 dev tap0

• Debian Wheezy IPv6 isn't configured with ifup post-up hook

  - by aef

  We recently set up a server on Debian Wheezy Beta 3 (x86_64) which has a native IPv6 connection. We configured the eth0 interface to get the IPv6 configuration through some post-up hook commands in /etc/network/interfaces. The result is, that after the booting the system up, there is only IPv4 and an auto-configured link-local IPv6 address configured on the interface, as if the command has never been executed. When we additionally place the commands after the call to ifup -a inside the /etc/init.d/networking init script, everything works as expected and we have a fully configured interface after booting up. This is quite an ugly way to configure the interface. What are we doing wrong with the ifup post-up hooks? Or is this a bug? The section from /etc/network/interfaces looks like this (IP-addresses changed): allow-hotplug eth0 iface eth0 inet static address 1.2.3.1 netmask 255.255.255.192 network 1.2.3.0 broadcast 1.2.3.63 gateway 1.2.3.62 dns-nameservers 8.8.8.8 dns-search mydomain.tld post-up ip -6 addr add 2001:db8:100:3022::2 dev eth0 post-up ip -6 route add fe80::1 dev eth0 post-up ip -6 route add default via fe80::1 dev eth0 I also tried it in this alternative way: auto eth0 iface eth0 inet static address 1.2.3.1 netmask 255.255.255.192 network 1.2.3.0 broadcast 1.2.3.63 gateway 1.2.3.62 dns-nameservers 8.8.8.8 dns-search mydomain.tld iface eth0 inet6 static address 2001:db8:100:3022::2 netmask 64 gateway fe80::1 What we added to /etc/init.d/networking: … case "$1" in start) process_options check_ifstate if [ "$CONFIGURE_INTERFACES" = no ] then log_action_msg "Not configuring network interfaces, see /etc/default/networking" exit 0 fi set -f exclusions=$(process_exclusions) log_action_begin_msg "Configuring network interfaces" if ifup -a $exclusions $verbose && ifup_hotplug $exclusions $verbose # Our additions ip -6 addr add 2001:db8:100:3022::2 dev eth0 ip -6 route add fe80::1 dev eth0 ip -6 route add default via fe80::1 dev eth0 then log_action_end_msg $? else log_action_end_msg $? fi ;; …

• Vmware player change dhcp server settings

  - by Tathagata

  I have a Windows Server 2003 running from a Vmware player on Win 7 box. The idea is to test Windows Deployment service in the virtual network. Is it possible to configure the vmware dhcp server with WDS related stuff(option 66, 67)? I found a few references where people were using the vnetlib.exe to start, stop the dhcp serverchange the subnet mask etc - but there's no info on how to get set the dhcp server options. DHCP config from the virtual network editor I do have the Workstation, without the license for it. In the Virtual network Editor, the DHCP settings for the network I'm using, only allows me to set the subnetmask, IP ranges and stuff like that. But not the dhcp options. DHCP server on the WDS server Authorizing the DHCP server in the guest WDS server fails. The VMware player can run its own dhcp server fro the virtual network with out any authorization from the Active directory - can I do the same, with Win dhcp server in the guest Win Server? ~~~~~ Can I authorize W2K8 DHCP server for private network, even when prohibited in enterprise network? says we have to run a third party dhcp server... :/.

• HAProxy, health checking multiple servers with different host names

  - by Marco Bettiolo

  I need to load balance between multiple running servers with different host names. I cannot set-up the same virtual host on each one. Is it possible to have only one listen configuration with multiple server and make the Health Checks apply the http-send-name-header Host directive? I am using HAProxy 1.5. I came up with this working haproxy.cfg, as you can see, I had to set a different hostname for each health check as the health check ignores the http-send-name-header Host. I would have preferred to use variables or other methods and keep things more concise. global log 127.0.0.1 local0 notice maxconn 2000 user haproxy group haproxy defaults log global mode http option httplog option dontlognull retries 3 option redispatch timeout connect 5000 timeout client 10000 timeout server 10000 stats enable stats uri /haproxy?stats stats refresh 5s balance roundrobin option httpclose listen inbound :80 option httpchk HEAD / HTTP/1.1\r\n server instance1 127.0.0.101 check inter 3000 fall 1 rise 1 server instance2 127.0.0.102 check inter 3000 fall 1 rise 1 listen instance1 127.0.0.101:80 option forwardfor http-send-name-header Host option httpchk HEAD / HTTP/1.1\r\nHost:\ www.example.com server www.example.com www.example.com:80 check inter 5000 fall 3 rise 2 listen instance2 127.0.0.102:80 option forwardfor http-send-name-header Host option httpchk HEAD / HTTP/1.1\r\nHost:\ www.bing.com server www.bing.com www.bing.com:80 check inter 5000 fall 3 rise 2

• Crond offset five minute schedule

  - by sam

  Is it possible to offset a cron script set to run every 5 minutes? I have two scripts, script 1 collects some data from one database and inserts it into another, script 2 pulls out this data and a lot of other data and creates some pretty reports from it. Both scripts need to run every 5 minutes. I want to offset script 2 by one minute so that it can create a report from the new data. E.G. I want script one to run at :00, :05, :10, :15 [...] and script two to run at :01, :06, :11, :16 [...] every hour. The scripts are not dependent on each other, and script 2 must run regardless of whether script one was successful or not. But it would be useful if the reports could have hte latest data. Is this possible with cron? Post; I have thought about using both commands in a shell script so they run immediately after each other but this wouldn't work, sometimes script 1 can get hung up on waiting for external APIs etc. so might take up to 15 mins to run, but script 2 must run every 5 minutes so doing it this way would stop/delay the execution of script 2. If I could set this in Cron it would mean script 2 would run regardless of what script 1 was doing

• SPF for two different outgoing servers?

  - by Marcus

  I have ran into a problem that I think someone should have a really clever answer for. Today we have our own mailserver that looks like "mail.domain.com" – which we use to send out mail to our customers (with a modified PHPMailer script). Usually around 5000 mails every day. Everything from customer support to invoices goes through there. The from-header is set to "[email protected]". We are now thinking of migrating to Google Apps for internal use (with 70+ users). However, we cannot use Gmails SMTP for sending "bulk" mails (they have a limit of 500 outgoing mails per day) so we really want to keep using our current system for sending automated mail to our customers – and using gmails SMTP for our internal use. So, how do we set up our SPF-records (Sender Policy Framework) for this? We do not want to get stuck in any filters for "spoofing" the sender from either type of account (the ones sent from our own server, and through Gmails). In short: we want to be able to use the same e-mail adress (for sending) on two different SMTP servers (and therefore two different IP-adresses). Anyone with a good knowledge off SPF who knows how to go about? Or if it is even possible? Anything else I should think of when switching to Google Apps?

• How is the extra mSATA SSD disk used/configured in a Dell XPS laptop?

  - by Mark

  Some machines in the new XPS laptop range from Dell come with a regular, large (500GB+) HDD and an additional 32GB m-SATA SSD. The only detail I can find about this extra drive on the Dell site is this: Store your important files, multimedia and photos with XPS 15’s large hard drive options. To get instant access to your media, choose an optional mSATA solid-state drive (SSD) that can boot up to twice as fast as a regular hard drive and resumes in less than 1 second. I'd like to know more about how this extra drive is set up and used, specifically: Is anything installed on it (e.g. OS files or a boot loader) or is it just used as swap space? Is the m-SATA drive visible as a lettered drive in Windows? (I'd guess not if it's used for swap file only.) Is this unusual configuration likely to cause any problems later down the line - e.g. when upgrading to Windows 8? As usual, Dell's sales team haven't been able to help. If anyone's actually got a Dell machine with this or a similar hard drive set-up and can give a definitive answer rather than speculation I'll accept the answer.

• how do I fix a wrong UUID in grub.cfg?

  - by mozerella

  I run Debian Wheezy alone on my PC and I recently copied the root partition to another with rsync as I found that worked well (I also know about dd and ddrescue but they leave unusable space on the new partition). I generated a new random UUID for the new partition with sudo tune2fs -U random /dev/hda9 and also updated fstab / and /home entries. Then as I know so little about GRUB I used a gui (GRUB Customizer) to probe for the new OS and add an entry to GRUB and the MBR -it makes an /etc/grub.d entry then updates GRUB. On startup, the GRUB list contains the new OS (on sda9) but it boots the first OS (which I copied from -sda5). /boot/grub/grub.cfg contains the new debian OS but it looks like this set root='(hd0,msdos9)' search --no-floppy --fs-uuid --set=root 64662470-0e58-4dfd-90ac-43227d773556 linux /boot/vmlinuz-3.2.0-2-amd64 root=UUID=cc3bca0d-aee4-4b9c-95c2-57212cc36d4d ro quiet initrd /boot/initrd.img-3.2.0-2-amd64 the 1st uuid is of sda9, but the 2nd uuid there is of sda5. I can change the 2nd uuid at startup (with E) and it boots sda9. So how can I get grub.cfg corrected so that the sda9 GRUB list entry boots from sda9 permanently?

• IP tables blocking access to most hosts but some accesses being logged

  - by epo

  What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

• Looking for a small, portable, port-mirroring ethernet switch.

  - by user37244

  I recently had a mac go haywire, taking half a minute or more to get www.google.com loaded. Getting its owner to give up the machine for repair was like pulling teeth - they were insisting that it must be something to do with the network, since so much had changed with the local configuration at about the same time their box went haywire. I eventually set up a port mirror to a box that I could remote to so I could show that the mac was only irregularly getting packets onto the network. Demonstrating this faced an additional challenge: the latency of the remote desktop software I was using meant that I had to point to timestamps instead of just the moment the packet flashed up on the screen as my evidence. This particular user was the reason this was so challenging this time around, but I would like to have a box that I can cart from desk to desk to use wireshark on my laptop at any station where I need it. 3com, cisco, netgear, etc. (ad nauseum), all make switches that can be configured for port mirroring, but in my case, the smaller, the better. For the sake of my sanity, I'll probably end up running it off a battery anyway. If my laptop had two ethernet ports, this would be easy. So, whaddya recommand for a device that requires 0 configuration at each powerup (though I'm fine with poking at it for a while to set it up initially.) Small, light, and cheap enough to get it past purchasing? Thanks,

• Tortoise SVN, find all non-added files?

  - by John Isaacks

  I am using Tortoise SVN on Windows. I have a deep directory structure (using cakephp). After creating several files I then went through and +added them. The new files show a ? next to them and a + next to them after set to add so it is easy to tell which files still need to be added. this is the same with folders. However if a new file is inside an old folder there will still be the green checkmark. You won't have any indicator telling you there is a new file. So I forgot to add one before a commit. This wouldn't be so bad as I could just add it and recommit. However, I also made this a tag, so I had recommit to the tag and the trunk. Anyways this wouldn't have been an issue if there was an indicator on existing folders that contain new files. Is there a way to set this up?

• Toshiba A205-5804 freezes when plugged in

  - by heron

  Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheating problem, the computer is not getting hot or anything related, I've already tried changing the AC adapter, booting only with AC and no battery, and also all of these suggestions: Try changing the following setting in the bios setup, under the 'Advanced' tab Dynamic CPU Frequency: Mode = Always Low (NOT DYNAMIC) My laptop has been running on AC power without a problem for 24hours, including many restarts, and when I went back to the original bios setting, the problem returned almost straight away. EDIT Other suggestions I found on the web from here and here: Set the power plan to high performance Set the power plan to "Minimal Power Management" (1 and 2 do conflict) Start - Control Panel - Device Manager -- Processor - disable one of two processors - reboot normally 4.Do this: Only plug battery into laptop Turn on the laptop and start Windows normally Plug AC adapter into laptop, the screen will freeze Leave the laptop the way it is for 12-24 hours After 12-24 hours, turn it off the hard way Once it is turned off, turn it back on. The laptop is working now. I have no idea of what can it be...

• Upgrading PHP, MySQL old-passwords issue

  - by Rushyo

  I've inherited a Windows 2k3 server running an XAMPP-installation from the stone age. I needed to upgrade PHP to facilitate an upgrade to MediaWiki to facilitate a new MediaWiki extension (to facilitate some documentation to facilitate doing my job to facilitate getting paid to facilit... you get the idea). However... installing a new version of PHP resulted in PHP's MySQL libraries refusing to communicate using MySQL's 'old style' 152-bit passwords. Not a problem in theory. The MySQL installation is post-4.1, so it should have the functionality to upgrade the user's passwords from 152-bit to 328-bit (what a weird hashing algorithm...). I ran the following: SET PASSWORD = PASSWORD('foo'); on MySQL but querying: SELECT user, password FROM mysql.user; returned just the same password I started out with - 152-bit. Now... I suspect you're thinking 'AHA! old-passwords is on!'. Unfortunately it's not - I've disabled it in the configuration (explicitly set it to 0), made doubly sure I have an absolute reference to that configuration file and ensured the service isn't using the --old-passwords flag. The service was reset after each and every operation. So I went onto another system and generated the 328-bit hash on there, copying the hash over to the first MySQL instance. Unfortunately, that didn't work either (I did remember to FLUSH PRIVILEGES). The application error is: "'mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool [...snip...] Is there anything else I can try to get PHP to recognise MySQL as not using the 'old insecure authentication'? MySQL seems to be stuck in 'old-passwords' mode and I can't get it out of it.

• How to extract attachments from Exchange 2003 database

  - by John

  I have an ancient Exchange 2003 server that I'm getting ready to retire. All user accounts have been migrated to Google Apps for Business, so no new mail is being sent or received on the server. There are less than 50 accounts on the server, but some are very large so that the whole Exchange database is between 10 and 20 GB. The largest account has over 100,000 messages. I believe that in the migration to Gmail, some attachments were not migrated. For peace of mind, I'd like to get the attachments out of the Exchange database. The only way I know of to do this is to set up a 2nd computer with Outlook on it, set up one of the accounts, and then sync the whole mail history and get the attachments out that way. Is there something simpler that I can do? Here are two possibilities: An Exchange attachment retrieval tool/script that pulls attachments for all accounts directly out of the Exchange database. An Exchange PST exporter tool/script that will export PST files for all accounts so that I can just load the PST files into Outlook at will.

• named responding recursive on norecurse queries

  - by Keks

  I have a server on which named is running. It is intercepted with another named server which it is not aware of. Querying the first named server results in timeouts. The server tries to resolve the query recursively. During that the firewall redirects the DNS Request from the first named server to the second one (the query from the first one is addressed to a e.g. a root server and has its "Recursion desired" bit set to 0). Despite that the second named responds to this request with a entirely or at least 1 level more resolved response than the first named server expects. So it ends up with a timeout even though it got a correct name server or even the full IP for the queried domain. In the first case the first name server tries to follow the authority domain ignoring the coresponding glue record and ends up in a loop it aborts: queried: google.com -> got from named#2: ns1.google.com -> ignore glue record and query: ns1.google.com -> got authority from named#2: google.com In the second case it ignores the answer section with the correct IP and instead tries to follow the name servers from the authority section, which ends up in the same dead end as case 1. So how can it be that the second named responds with recursive results even though the bit was explicitly set to 0 in the request from the first named?

• Delayed internet access

  - by Joel Coel

  When I (and presumably my users) first start up or log in to my computer I can't get internet access until several minutes after logging in. Internet pages like serverfault.com will time out. During this time I can access internal web servers. Sometimes pinging the gateway seems to fix the problem. I'm using Windows 7 on this machine with wifi, and the problem seems limited to the wifi network, which is on a separate vlan. The wired network does not share the problem, but I know it's not the wifi connection itself because the internal sites work. The wifi access point is attached to a 3Com 4200 switch, with the port set for vlan 2 untagged, vlan 1 tagged. The 4200 has a fiber connection to a 3Com 4900SX fiber switch that acts almost as a router here. The fiber connection is vlan 1 untagged vlan 2 tagged at both ends. The gateway is then attached to a different 4200 (vlan 1 untagged, vlan 2 tagged) that has a similar fiber connection to the 4900SX. vlan 2 has 192.168.8.0/22 IPs, vlan 1 has 10.1.0.0/16 IPs. The 4900SX has an interface for both vlans (10.1.1.1/192.168.8.1), as does the gateway (10.1.1.5/192.168.8.5). There is one dchp server for both vlans on the same switch as the gateway. It chooses a dhcp scope based on the interface used by the 4900sx to forward the dhcp request. There is also a network access list on the 4900sx set to deny all vlan2 traffic to any 10.1.x.x host, with exceptions made for a few servers, including dhcp, 4900sx, and the gateway. I think that about covers it. Any ideas on why internet access would be delayed like this?
