• Computer hangs at BIOS screen. Cannot enter setup.

  - by d2jxp

  I have an HP Pavilion a6500f (it's a year out of warranty) and it's hanging on the blue HP BIOS screen. If I mash F10 while it's starting up, it will say "Entering Setup..." but I will see no results. It will hang there and not do anything. If I actually wait until I can see the screen and then hit F10, there's no response at all and the computer will sit at the BIOS menu. I've dusted and cleaned it out, reseated the memory, switched the RAM slots, and reset the CMOS battery using the reset jumper. I'm out of ideas. I'm pretty sure it's not a hard drive issue, since my problem is at the BIOS. After this post, I'll disconnect the hard drive and try to just boot without it. Anyone have any other ideas? Edit: Okay, so I tried disconnecting the hard drive and now I can get back into the BIOS. I reconnected it and I'm locked out again. So the problem is my hard drive.. I guess I should delete this post unless someone has any ideas as to what's wrong with the drive?

• P2V Wouldn't Boot, Rebuilt initrd, Need to Clean Up

  - by Mike Soule

  We have a CentOS 5.4 server (build 2.6.18-164.el5xen). We went to P2V this server so we can have redundancy, the physical only has one PSU. The P2V only completed 99% of the way, we have a VMWare ticket opened, but they marked the ticket as low priority. I was able to boot into a rescue disc of Red Hat 5.4 and rebuild the initrd with the help of this blog post. Now the only issue is the original server had a modified initrd, which was also from a different OS build and made by an outside provider. We do not have a document outlining modifications. My question is, is it at all possible to copy the initrd off of the physical server and replace it on the virtual and some how have the virtual machine boot? Thanks for any input. Edit: I copied the initrd img from the physical and it recreated the original issue. Here is a screen capture of the error. http://i.imgur.com/MqC73.jpg Edit2: echo Scanning logical volumes lvm vgscan --ignorelockingfailure echo Activating logical volumes lvm vgchange -ay --ignorelockingfailure VolGroup00 resume /dev/VolGroup00/LogVol01 echo Creating root device. mkrootdev -t ext3 -o defaults,ro /dev/VolGroup00/LogVol00 echo Mounting root filesystem. mount /sysroot

• iptables blank after reboot

  - by theillien

  We've started encountering an issue with iptables on our RHEL 6.3 systems in that after a reboot, when the service starts, the rules are not loaded. We get the empty ruleset: [msnyder@matt-test ~]$ sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination This is in spite of the fact that we have rules defined and the service is, indeed, running. That I know because when I run service iptables start it simply drops back to the prompt. If I run service iptables restart it actually stops and then restarts the service. And, of course, if I run service iptables stop it indicates that iptables is actually stopping. Knowing that I need to restart the service, I do so and the rules load up properly. They simply don't get loaded after a reboot. Unless they get loaded differently during a reboot I don't see how our rules would be wrong. If they were, they wouldn't even load during a service restart. Has anyone else ever encountered this? EDIT: The rules are already saved in /etc/sysconfig/iptables. They are not added on the fly from the command line so service iptables save is unnecessary.

• nVidia performance with newer X and newer driver abysmal with Compiz

  - by Nakedible

  I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem. EDIT: In the end, nothing really worked, and I got really annoyed with the state of compiz and its support in Debian. Many nVidia driver revisions have passed and I am using Gnome 3 now, so I am accepting the best answers to this question even though the issue was not resolved.

• Vmware Workstation, Win7 host, Ubuntu guests with Nat + Host-only networks but they cannot connect to the Internet

  - by Ikon

  I have a Win7 host machine with Vmware Workstation. In the workstation I have 3 Ubuntu installed. All 3 Ubuntu guests have a Nat network - to access the internet without asking the router for a local address - and a Host-only network - to connect all Ubuntu quests and the host in a private network for internal communication, without touching the router. When I try to make any of the Ubuntu quests to get data from the internet - assuming that they would figure out that the Nat-ed interface can access the requested data - they fail and report that there is no route to my query. If I disconnect the 2nd interface on the Ubuntu guests with the Host-only network and restart networking, they start to know the route to the internet. Odd, during the installation of the guests they asked which of the 2 given interfaces - with Nat and Host-only config - should be used to get updates during installation and they oddly managed to get the updates. Not so after the installation has finished and rebooted. I have checked the Virtual Network Editor that the Nat interface should use my real network card to access the net, so there should be no problem. I wish not to use the router's dhcp service to give the Ubuntu quests an address, and also I don't want the guests to be accessable from the local network directly, but only by the host - that's the Host-only network is for. Any suggestions? Edit: 192.168.189.0 is the Nat interface and 192.168.7.0 is the Host-only. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.7.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.189.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.189.2 0.0.0.0 UG 100 0 0 eth0

• Per-mailbox IMAP settings in Exchange 2003 apply successfully but revert to server default

  - by erictheavg

  The title says most of it. I have a Spiceworks mailbox that connects to our Exchange Server 2003 box via IMAP for receiving help desk issues. But for complicated reasons, I want it to receive those emails in text-only format. So, I discovered that you can just go to: Exchange System Manager Administrative Groups First Administrative Group First Storage Group Mailbox Store Mailboxes Right-click the mailbox, Configure Exchange Features Edit the properties for IMAP Set that mailbox to only receive message bodies as plain text. I click OK, then Next, it reports success, and I assume I'm done. But then when I go right back to where I was, I see that "Use protocol defaults" is still checked. Anyone have a clue why this would be? Some other details: I'm logged in as Administrator when I do this. I can't change this setting for the entire IMAP virtual server because some regular users use it. I only have one IP address to play with, which means I can't create another IMAP virtual server. Any suggestions or ideas are greatly appreciated!

• Korean characters not appearing in Korean Windows XP computer

  - by user13267

  I am using a Korean software (with a partial English interface) in a Korean Version of Windows XP SP 3 However, in parts of the software, even when I change the interface to Korean, Korean letters show up as random characters, as shown here: This is happening at others parts of the software as well, and I am not sure what is the difference between the places where this is happening, and places where this is not happening. For example, a command button where Korean letters are showing up properly is shown below: This software is a video conferencing software and has a chat feature as well. When I type into the chat box, i can see the Korean letters appear properly at my side, but when I press Enter and send the message, it changes into random characters as shown above in the chat box. What could be the issue here? Could it be a missing font in my computer? Since this is a Korean Windows installation I was hoping everything would work properly by default. What can be done here? EDIT 1: I asked some other people who are using this software, and they think that the problem is at my end, and playing around with the Regional and Language Settings might solve the problem. Also, they suggested I install all the language packs related to Korean display. But it looks like all the language packs have been installed, and my location is set to Korea in Regional and Language Settings in Control Panel, and I still have this problem. Also, I have had similar problems with displaying Korean on an English Windows XP computer. This answer suggested some solutions, but I still do not quite understand exactly what I have to do (at that time I had not fixed the problem, as I later on changed the computer). If I follow that answer, what fonts exactly do I need to install?

• Exchange - inbound email only works from some servers

  - by Kryptonite

  I am having a problem where inbound mail from outside only works when sent from certain hosts. For example, when I send myself an email from my personal gmail account all is well, as the logs show: 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 EHLO 250 - - 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 STARTTLS 220 - - 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 STARTTLS 220 - - 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 EHLO 250 - - 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 MAIL 250 - - 2012-09-05 18:14:16 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 RCPT 250 - - 2012-09-05 18:14:48 209.85.223.175 mail-ie0-f175.google.com SMTPSVC1 MAILSVR 192.168.1.79 0 QUIT 240 - - However, if I sent from my personal Yahoo account, I get this response: Sorry, we were unable to deliver your message to the following address. <[email protected]>: Remote host said: 530 5.7.0 Must issue a STARTTLS command first [MAIL_FROM] (NB: Nothing appeared in the smtp log for this message.)

• Can a website see/know my MAC address even if I use a VPN?

  - by ilhan

  I have searched other results and read many of them but I could not get an enough information. My question is that can a website see my MAC address or can they have an information about that I'm the same person under these conditions: I am using a VPN and I use two IPs: first one is normal one, the second one is the VPN's IP. I use two browsers to hide behind browser fingerprinting. I use both browsers with Incognito Mode. I always use one for normal IP, one for the VPN IP. I do not know that if the website uses cookies or not. But can they collect an enough information to prove that these two identities belong to same person? Is there any other way for them to see that I am the same person? I use different IPs, different browsers and I use both browsers in incognito mode. I even changed one of browsers language to only English. So even if they collect my info from browser, they will see two browsers using different languages. (Addition after edit): So I have changed my IP and browser information and the website can not reach this information anymore to prove that I am the same person using two accounts. Then let's come to the title: Can they see my MAC address? Because I think that it is the last way that they can identify me and my main question is that. I wrote the information above to mention that I changed IPs and I have some precautions to avoid browser fingerprinting (btw my VPN provider already has a service about blocking it). I wrote them because I read similar advices in some related questions but my question is that can they see my MAC address (or anything else that can make me detected) despite all these precautions. And lastly, Is there an extra way to be anonymized that I can do? For example, can my system clock or anything else give an information? Thanks in advance.

• Windows Server 2012 licensing issue preventing RDP connections?

  - by QF_Developer

  I am witnessing an unusual behaviour on 1 of 5 Windows Server 2012 R2 machines (clean install) that is preventing any remote connections from being established via RDP. I have run through the prerequisites for RDP here but I am finding that any remote connection attempt instantly stops the "Windows Protection Service". When I check the event logs I see the following entry. The Software Protection Service has stopped Event ID: 903 Source: Security-SPP From what I have read Security-SPP is tasked with enforcing activation and licensing, it appears that RDP requires this service to be in the running state. Is it possible that I have inadvertently activated this instance of Windows with a key that has already been associated to another instance (We have 5 keys as part of an MSDN subscription)? Would this be sufficient to block RDP access? When I look under System Properties (Windows Activation) it states that Windows is activated and there are no other obvious indicators that there's a licensing issue. EDIT 1: I ran a Powershell script to display the product keys for all servers in order to check for any duplication. For the problematic server I am getting the message The RPC server is unavailable.

• How can I ensure that my static ip address is read from /etc/network/interfaces rather than dhcp?

  - by jonderry

  This is a follow up to the following question. I'm trying to set a static IP by changing /etc/network/interfaces to the following: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.2.133 netmask 255.255.255.0 gateway 192.168.2.1 dns-nameservers 8.8.8.8 and then running /sbin/ifdown eth0; /sbin/ifup eth0. However, the change in IP address doesn't appear to take effect without editing /etc/dhcp/dhclient.conf and commenting out the following before running ifdown; ifup: request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, domain-search, host-name, dhcp6.name-servers, dhcp6.domain-search, netbios-name-servers, netbios-scope, interface-mtu, rfc3442-classless-static-routes, ntp-servers, dhcp6.fqdn, dhcp6.sntp-servers; Strangely, after commenting out this line, running ifdown; ifup works, but when I uncomment it, the behavior does not revert to the previous behavior of ignoring changes to my settings in /etc/network/interfaces (this doesn't seem like a problem, but I really need to be able to repeat this problem so that I can be confident that my solution is robust) Also, I'd rather not have to edit /etc/dhcp/dhclient.conf to change my static IP since it seems I should be able to do this by only editing interfaces. Can anyone explain the issues I'm seeing above and suggest the best way of making changes to static IP addresses take effect that admits reproducibility so that I can be sure that my approach works?

• Allowing access to company files accross the internet

  - by Renaud Bompuis

  The premise I've been tasked with finding a solution to the following scenario: our main file server is a Linux machine. on the LAN, users simply access the files using SMB. each user has an account on the file server and his/her own access rights. user accounts are simple passwd/group security accounts, not NIS/LDAP. The problem We want to give users (or at least some of them, say if they belong to a particular group) the ability to access the files from the Internet while travelling. Ideally I'd like a seamless solution. Maybe something that allows the user to access a mapped drive would be ideal. A web-oriented solution is also good but it should present files in a way that is familiar to users, in an explorer-like fashion for instance. Security is a must of course, and users would be expected to log-in. The connection to the server should also be encrypted. Anyone has some pointers to neat solutions? Any experiences? Edit The client machines are Windows only.

• Offline productivity

  - by Frank Meulenaar

  On some days I'm commuting 2hs (oneway) in the train. I don't have any mobile internet nor is there always WiFi service in the train. Because of security reasons I can't do any work in the train so I'm trying to work on my geek time. I'm looking for general solutions on how to do this (I'm on FireFox/Windows but I don't think it matters) Email works perfectly with gmail offline. It syncs directly when online and remembers complicated stuff. So far I used the ScrapBook plugin to store an website. It works good, but I have to download my favorite news page every day again - I want it to sync as soon as possible. It would even be more awesome if I could click a page on my desktop and my laptop would sync as soon as it has the chance. (edit: maybe the autosave plugin for scrapbook can do this) Similarily, I use the Downloadhelper plugin to download youtube vids, but I'd like something that automatically downloads videos from a given channel. Any tips are welcome. So far my early morning schedule is: wake up, power on laptop, make coffee, power off laptop and leave within 10 minutes (enough time for GMail to sync) but I can imagine a system where my laptop stays on during the night (or boots before I wake (and makes me coffee :])).

• Changing the Start Menu Power Button - Setting does not work: only (Shut down) is available

  - by Martin

  This is the second time I try to change this setting on a Vista based OS and I can't get it to work again. OS: Windows Server 2002 SP2 (not R2) = Microsoft Windows [Version 6.0.6002] = Vista When I go to: Power Options - Change Plan Settings - Change advanced power settings - Power buttons and lid - Start menu power button - Setting: the available combo box will only show the option Shut down. No other options are available. This server is part of a domain and has not been set up by me. I have not yet talked with the domain admin, but as far as I could tell from googling, only Win7 has group policy options for the start menu. (And yes, OC I will talk to the domain admin to see if he has any clue - which I doubt.) (Edit: I have now talked to our domain admin, and he's got no clue either.) I'm responsible for this server and a local administrator but not a domain administrator. I switched off User Account Control (UAC) yesterday without problems. Since I always log into this machine via RDP and this being a server, the natural choice would be the option (Log out) and not (Shut down). What can I do to fix it or to find out why it cannot be changed? Thanks!

• HAProxy crashes on all requests in 1.5-dev12

  - by Daniel Hough

  I'm having an issue where HAProxy is crashing with no explanation when I switch from 1.4.12 to 1.5-dev12. The reason I'm switching is for the SSL offloading. My config file doesn't have any errors, it's quite simple and it works well with 1.4 - but for some reason when I run it with 1.5-dev12 I see the logs noting that the two backends I have have been set up, and then when I hit one of the frontends, I get an HTTP 400 in the browser and suddenly HAProxy isn't running anymore when I check. I understand that a common workaround to the lack of SSL support for HAProxy is to use Stud, and I may go with that since I am in need of an SSL solution for my service, but before I dele into that world I thought I might see if anybody has experienced the same problems and might know how to fix it. The server is Ubuntu 10.04 and I followed the make instructions on the Exceliance blog here. EDIT: On the advice of Kyle Brandt, I did a bit more investigation. I attached gdb to the haproxy process and when the crash occurred this is what I got: Program received signal SIGSEGV, Segmentation fault. 0x0804e5c2 in dequeue_all_listeners (list=0x9e1a418) at src/protocols.c:184 184 list_for_each_entry_safe(listener, l_back, list, wait_queue) { P.S. HAProxy is awesome, so thank you Exceliance for providing us with something so useful :)

• Do background processes get a SIGHUP when logging off?

  - by Massimo

  This is a followup to this question. I've run some more tests; looks like it really doesn't matter if this is done at the physical console or via SSH, neither does this happen only with SCP; I also tested it with cat /dev/zero > /dev/null. The behaviour is exactly the same: Start a process in the background using & (or put it in background after it's started using CTRL-Z and bg); this is done without using nohup. Log off. Log on again. The process is still there, running happily, and is now a direct child of init. I can confirm both SCP and CAT quits immediately if sent a SIGHUP; I tested this using kill -HUP. So, it really looks like SIGHUP is not sent upon logoff, at least to background processes (can't test with a foreground one for obvious reasons). This happened to me initially with the service console of VMware ESX 3.5 (which is based on RedHat), but I was able to replicate it exactly on CentOS 5.4. The question is, again: shouldn't a SIGHUP be sent to processes, even if they're running in background, upon logging off? Why is this not happening? Edit I checked with strace, as per Kyle's answer. As I was expecting, the process doesn't get any signal when logging off from the shell where it was launched. This happens both when using the server's console and via SSH.

• ASP.Net Session Timing Out Rapidly

  - by Zac

  We have an ASP.Net 3.5 website running on Windows Server 2008 with IIS7. The session timeout period for this site is configured to be 20 minutes - however, it is currently lasting for between 40 and 50 seconds. After researching the problem we investigated several configuration values which could be involved in the timeout period but none of them are set to less than 20 minutes. The areas we look are as follows: web.config system.web/sessionState element (20 minutes). web.config system.web/authentication/forms element (not present, defaults to 30 minutes). Sites/{website}/ASP/Session Properties/Time-out (20 minutes). Application Pools/{appPool}/Advanced Settings/Process Model/Idle Time-out (20 minutes). We've also noted that the CPU is staying around 0% and that RAM usage is flat-lining around 1.07 GB (of 8 GB available) - so there is no performance-based reason for IIS to be recycling the Application Pool as far as we can tell. Are there any settings we've overlooked which could cause the session timeouts to be expiring so quickly? EDIT A couple of additional points: This is not occurring in development, only on the server. The session is not sliding (i.e. if we refresh the page a few times it still times out approximately 40 - 50 seconds after the session was created.

• Rkhunter reports file properties have changed

  I am running a fully updated LTS copy of Ubuntu server. Today I ran rkhunter (as I do from time to time). This is the output I got: Warning: The file properties have changed: [15:52:25] File: /bin/ps [15:52:25] Current hash: f22991ec93ae966c856d367f42fc3d8a484bd827 [15:52:25] Stored hash : 1892268bf195ac118076b1b0f53e7a637eb6fbb3 [15:52:25] Current inode: 142902 Stored inode: 130894 [15:52:25] Current file modification time: 1324307913 (19-Dec-2011 07:18:33) [15:52:25] Stored file modification time : 1260992081 (16-Dec-2009 11:34:41) Warning: The file properties have changed: [15:52:33] File: /usr/bin/ldd [15:52:33] Current hash: f1e2ca5aa3a28994e2cebb64c993a72b7d97b28c [15:52:33] Stored hash : 295d9cedb121a5e431a39a6d201ecd7ce5640497 [15:52:33] Current inode: 2236210 Stored inode: 2234359 [15:52:33] Current size: 5280 Stored size: 5279 [15:52:33] Current file modification time: 1331165514 (07-Mar-2012 16:11:54) [15:52:33] Stored file modification time : 1295653965 (21-Jan-2011 15:52:45) Warning: The file properties have changed: [15:52:37] File: /usr/bin/pgrep [15:52:37] Current hash: 3eada9a96760f3e2c9111cfe32901d1432813c1d [15:52:37] Stored hash : ce265d0db9964b173fe5036f703a9b8d66e55df3 [15:52:37] Current inode: 2229646 Stored inode: 2224867 [15:52:37] Current file modification time: 1324307913 (19-Dec-2011 07:18:33) [15:52:37] Stored file modification time : 1260992081 (16-Dec-2009 11:34:41) Warning: The file properties have changed: [15:52:41] File: /usr/bin/top [15:52:41] Current hash: 6be13737d8b0950cea2f1ae3a46d4af713dbe971 [15:52:41] Stored hash : c7b495ecef3982eeb6f08a511861b1a1ae8775e6 [15:52:41] Current inode: 2229629 Stored inode: 2224862 [15:52:41] Current file modification time: 1324307913 (19-Dec-2011 07:18:33) [15:52:41] Stored file modification time : 1260992081 (16-Dec-2009 11:34:41) Warning: The file properties have changed: [15:52:53] File: /usr/sbin/cron [15:52:53] Current hash: e783ca973f970aa8a4bf5edc670e690b33914c3d [15:52:53] Stored hash : 4718257a8060736b9058aed025c992f02a74a5a7 [15:52:53] Current inode: 2224719 Stored inode: 2228839 [15:52:54] Current file modification time: 1330965568 (05-Mar-2012 08:39:28) There were also a few other I left out. Has my server been rooted? I am running fail2ban and do monitor failed ssh logins. nothing has come up. Could someone compare these hashes to their copy of Ubuntu Server (lts)? Please tell me these are false positives..... Edit: is something else like rkhunter I can run for a second scan?

• I have bought a custom domain and am using it with Gmail. All My mail is being sent as spam. What can I do?

  - by Leonnears

  A while ago, I purchased my own custom domains for my websites. Before I moved them to Gmail, I just created the e-mails in my CPanel at Bluehost.com and worked from there. When the setup was like that, I could send and receive e-mail fine, and it wouldn't be marked as spam. Now I have moved these custom domains to send and receive e-mails at Gmail using Google apps. I have done everything. I have marked the domains as "Authorized" and I believe that should be enough for the mail I send with these custom e-mails is not send as spam. If it matters, I have configured my iPhone to use these custom domains with it and I'm sending all the e-mail from it. What can I do? I started doing all this today but apparently the DNS changes have already taken place. Is there something I have to do, or is it a matter of waiting 48 hours for my mail to not be marked as spam by other providers yet? EDIT: If I send mail via Gmail itself, the mail is delivered fine. If I use my iPhone however, it gets marked as spam.

• How can I use an own asp page as 404 error page on a Windows 7 pro IIS 7.5 local installation

  - by Edelcom

  Running Windows 7 Pro Running local IIS 7.5 ( for web development purposes ) Edited hosts file to be able to use http://www.sitestepper.dev Site build in subfolder of the inetpub/wwwroot/staplijst Site can be viewed using http://www.sitestepper.dev/staplijst/whatever-page.htm I have an http://www.sitestepper.dev/p.asp page I would like to call when an unknown page is requested. This technique works fine on the deployed version of this web site ( deployed on an Windows 2003 server running IIS 7 - not sure about the 7 but it is the version deployed with Windows 2003 server ). I tried ( in the Edit Custom Error Dialog ) : Execute a URL on this site: with value /staplijst/p.asp and Respond with a 302 redirect: with value http://www.sitestepper.dev/staplijst/p.asp I tried this in the properties of the 'Default Web Site' , and I tried this at the staplijst level. Even tried it with values without the /staplijst. I restarted the default web site after each change. And even stopped/started the Web service. But nothing seems to work, I keep getting the 'Server Error In Application "DEFAULT WEB SITE"' , HTTP Error 404.0 error. What am I missing here - probably something obvious, but I don't see it ? Thanks in advance

• iptables: How to combine DNAT and SNAT to use a secondary IP address?

  - by Que_273

  There are lots of questions on here about iptables DNAT/SNAT setups but I haven't found one that solves my current problem. I have services bound to the IP address of eth0 (e.g. 192.168.0.20) and I also have a IP address on eth0:0 (192.168.0.40) which is shared with another server. Only one server is active, so this alias interface comes and goes depending on which server is active. In order to get traffic accepted by the service a DNAT rule is used to change the destination IP. iptables -t nat -A PREROUTING -d 192.168.0.40 -p udp --dport 7100 -j DNAT --to-destination 192.168.0.20 I also wish all outbound traffic from this service to appear to come from the shared IP, so that return responses will work in the event of a active-standby failover. iptables -t nat -A POSTROUTING -p udp --sport 7100 -j SNAT --to-source 192.168.0.40 My problem is that the SNAT rule is not always run. Inbound traffic causes a connection tracking entry like this. [root]# conntrack -L -p udp udp 17 170 src=192.168.0.185 dst=192.168.0.40 sport=7100 dport=7100 src=192.168.0.20 dst=192.168.0.185 sport=7100 dport=7100 [ASSURED] mark=0 secmark=0 use=2 which means the POSTROUTING chain is not run and outbound traffic leaves with the real IP address as the source. I am thinking I can set up a NOTRACK rule in the raw table to prevent conntracking for this port number, but is there a better or more efficient way to make this work? Edit - Alternative question: Is there a way (in CentOS/Linux) to have an interface that can be bound to but not used, such that it can be attached to the network or detached when a shared IP address is swapped between servers?

• VNC Server that can be used from command line?

  - by jesusiniesta

  I'm looking for a replacement for a custom vnc server that we have been using in my company for a long time. I need a simple executable that can be run from command line by an IT Support software without the user noticing it (our application will warn the user, we don't want him to see we are using that VNC sever). I need it to support Windows and preferably also OSX. The only option I've found is UltraVNC, but I can't configure it from command line to accept loopback connections without authentication. We have already a whole VNC Viewer + VNC Repeater + Bouncers architecture, and the only missing piece is the VNC Server. Do you know any solution you could suggest me? I'm afraid I'll end up developing a new VNC server myself, may be based on an open source one. EDIT: When I said I don't want the user to notice this VNC server, I should have added that I don't want him even noticing the installation. So better if it can be installed silently or can be executed as a portable executalbe (for instance, ultravnc can be installed and ran as a service from command line, or simply executed quietly, with only a notification icon; its problem is that I can't run it without authentication).

• Notebook display problem (multiplication)

  - by SubniC

  Hi, I'm having some troubles with the display of a LG E500 notebook. The thing is that without any known reason the display starts to show the screen divided in eigth parts and each part show the display image as if I had a matrix of eigth displays :) I thought it could be some kind of refresh rate problem or driver related, but it is happening at boot-up as well and the BIOS. I got the computer completely unassambled yesterday and I check all the wires and connectors looking for something broken or unconected, but without luck... You can see a picture here of the problem (sorry for the low quality, but I think it illustrate the problem. EDIT 1: I uploaded a new pictrue, here you cans ee the problem better :) There are three horizontal lines that you can see just between the windows. You can see the grey line at the first moment you turn on the computer and the after the duplicated screens show up just like if they where arranged over a grid (over the horizontal lines...) I hope it makes any sense. Do you know what could be happening? or can you tell me what would you do? Thank you very much for your help.
