• iconv supports too few encoding

  - by schemacs

  iconv -l outputs too few encodings on CentOS 6.5: $ iconv -l 10646-1:1993, 10646-1:1993/UCS4, ANSI_X3.4-1968, ANSI_X3.4-1986, ANSI_X3.4, ASCII, CP367, CSASCII, CSUCS4, IBM367, ISO-10646, ISO-10646/UCS2, ISO-10646/UCS4, ISO-10646/UTF-8, ISO-10646/UTF8, ISO-IR-6, ISO-IR-193, ISO646-US, ISO_646.IRV:1991, OSF00010020, OSF00010100, OSF00010101, OSF00010102, OSF00010104, OSF00010105, OSF00010106, OSF05010001, UCS-2, UCS-2BE, UCS-2LE, UCS-4, UCS-4BE, UCS-4LE, UCS2, UCS4, UNICODEBIG, UNICODELITTLE, US-ASCII, US, UTF-8, UTF8, WCHAR_T But on my Ubuntu the list seems much longer, here is different: CentOS6.5: $ php -a php > echo iconv('utf8', 'gbk', 'abc'); PHP Notice: iconv(): Wrong charset, conversion from `utf8' to `gbk' is not allowed in php shell code on line 1 php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.12 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 Ubuntu 14.04: $ php -a Interactive mode enabled php > echo iconv('utf8', 'gbk', "abc\n"); abc php > quit $ php -i|grep iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.19 iconv.input_encoding => ISO-8859-1 => ISO-8859-1 iconv.internal_encoding => ISO-8859-1 => ISO-8859-1 iconv.output_encoding => ISO-8859-1 => ISO-8859-1 But I don't want to recompile glibc(this will be huge mount of work), any idea on how to ad new encoding support?

• Strange ASP.NET Queue Performance Counters Behavior?

  - by LemurTech

  We have an ASP.NET 2.0 site running in classic mode. I am seeing very strange behavior in the performance counter values. Perhaps these are bugs (I've been all over Google trying to verify this, without much luck), or perhaps it is just my inexperience with monitoring these things. This PerfMon graph (http://imgur.com/Jv5io5J) represents a load test where I add up to 350 virtual users to the site, at a rate of about 1/sec, performing relatively simple page browsing. At the end of the test, I gradually taper off the number of users. This is a 4 CPU server. Machine.config settings for are at the defaults. The solid blue line is ASP.NET Apps v2.x\Requests Executing for the application in question. The profile makes perfect sense, with a quick ramp-up to 32 executing requests (minWorkerThreads x 4CPUs), followed by a slower ramp-up to 48 ((maxWorkerThreads - minWorkerThreads) x 4CPUs). The solid yellow line is ASP.NET v2.x\Requests Queued. Again, this makes sense: after the initial 32 request threads are activated, the queue begins to build as new thread initialization can't keep pace with incoming requests. But as executing requests reaches its highest possible value of 48, the counter for ASP.NET Apps v2.x\Requests Queued (green solid line) suddenly springs to life and maintains step with the yellow counter. As far as I can tell, and with no other apps running on the server, these two counters should have had the same values from the start. One other odd thing: The counter for ASP.NET v2.x\Request Wait Time (dotted yellow line) also does not spring to life until executing requests reaches 48. Shouldn't I be seeing values here from the moment ASP.NET v2.x\Requests Queued begins to build? And likewise, why would ASP.NET Apps v2.x\Request Execution Time (dotted blue) increase significantly only after that peak of 48 is reached? Shouldn't it ramp-up gradually along with queued requests?

• Data recovery on a data HDD (no OS)

  - by aCuria

  I am helping a family member with a dead hard disk. It is a seagate 200Gb 3.5" HDD in one of those old-school external enclosures. The problem was that windows failed to detect the hard disk when plugged in through USB. I removed the hard disk from its enclosure, and plugged it into my desktop PC. The BIOS does detect it upon POST, but unfortunately windows 7 would refuse to boot. It will get stuck on the loading screen with the glowing windows logo. Safe mode doesn't help either. What options do I have before going for some professional data recovery? edit: Someone modified the Title to something completely different from what I was asking, i just changed it back. 1) 2 HDD drives, DiskA(Dead), DiskB(my OS disk) 2) when B is connected to my system, everything works fine 3) when A AND B is connected, failure to boot. POSTs fine, but windows wont load 4) A has NO OS, its PURE data. It came from an EXTERNAL HDD enclosure which doesnt belong to me, and im trying to do data recovery.

• Samba and Windows 7

  - by John Gaughan

  I built a new computer with the intention of it being primarily a home file server. Here is my setup: one desktop with Windows 7 64 HP one laptop with Windows 7 64 HP one desktop with Kubuntu 11.10 (server) The two desktops use static IPs, and I have hostnames mapped in the HOSTS files on all three systems. I have the same username/password combo on all three systems. I have been trying for a while now to set up Samba so the Windows 7 systems can see and use it. Even if I can get the server to show up, Windows is unable to log in. One of the first things I did was to enable LMv2 authentication, which this version of Samba (3.5.11) supports. The workgroup is set correctly. I can normally see the server, but cannot authenticate. Windows homegroup is turned off. Pinging between machines works fine, and the two Windows 7 systems work together flawlessly. What I am trying to do is set up Samba to use peer to peer networking using NTLM security and user-mode authentication. According to the documentation this is possible, but there are no examples that I could find. In all the googling I have done, I see a lot of people asking how to set this up but it either works for someone else and not for me (no idea what I'm missing), or it doesn't work. Has anyone gotten this to work? Is there a place I could download a smb.conf that is set up to work in this environment?

• Fedora 9 not reconizing hard drive

  - by Andrew Jones

  I am installing Fedora 9 to a PC (specifications at the bottom) and have had a lot of trouble with it recognising the hard drive. To get the Fedora installer to recognize it in the first place I had to pass "ata_generic.all_generic_ide=1 pci=nomsi" to the kernel, after which it installed OK. However, now when I boot the installed OS, I get a "could not find filesystem '/dev/root'" error. I tried passing the same arguments to the kernel at boot as I did when installing but to no avail. I have tried using the default LVM layout and defining manual ones but it made no difference. There is no option in the BIOS to enable AHCI or anything like that, in fact the BIOS is very limited in most respects. I can get into the system by using the installation CD in rescue mode (with those extra kernal parameters) but I'm not sure what to do once in there... Unfortunately using a more recent version of Fedora or even another Linux distribution altogether isn't an option becuase of outside constraints - which is annoying since I know for a fact Ubuntu works fine on this setup. I have not been using Linux that long, so treat me like an idiot - I am one. Any help would be greatly appreciated, thanks! System spec: Intel Atom Z530 CPU @ 1.6 GHz Intel US15W chipset 1 GB DDR2 160 GB SATA harddisk (Samsung HM16HI) 1000 Mbit/s Ethernet port Phoenix BIOS

• Umount stale glusterfs partition

  - by Khaled

  I am using glusterfs on several Ubuntu servers: two of them are running glusterfs servers in replication mode. Without any clear error, the glusterfs partition became stale and the system shows this error when I try to access the stale partition: Transport endpoint is not connected Also, when running ls -l on the parent folder I get: d????????? ? ? ? ? ? myfolder I tried all types of commands that I can find to umount this partition, but I could not get it done: umount -l /path/to/mount/point umount -f /path/to/mount/point Also, using fuser command to show processes accessing this folder did not work. Unload the fuse kernel module can not be done as it is clear from the kernel config that fuse is built into the kernel and not a loadable module. I found this line in /boot/config-2.6.32-24-server CONFIG_FUSE_FS=y I have been left with two options: Reboot the system. Create another mount point like myfolder2 and mount this again using sudo glusterfs -f /etc/glustefs/glusterfs.vol /path/to/folder2. Of course, I have chosen to go with option 2. Anyone faced such an issue before? Anyone has a better solution for such a case?

• Network config for KVM on physical machine with single NIC and single public IP

  - by neo0

  I have a physical machine running CentOS 6.4 and I will rent a place to run it in a data center. I want to install KVM on that machine to run some virtual machines. The problem is my physical machine have only one NIC and the data center give me a public IP for that interface. So how should I configure network on the physical machine to make it assign for each vm a private IP that can connect to Internet. If I create a br0 bridged with eth0 interface and create a vm with option --bridge=br0 then KVM could not assign an IP for the vm so setup can not be done. Should I use NAT mode? Does KVM have any host-only network like Virtualbox? But the vm still has to connect to outside? Thank you! Update I install the guest network using NAT (--network network:default) and then I only have to port-forwarding from the host. But if I config br0 bridged with physical eth0 then the guest can not get an IP from boot. So I removed the br0 and it worked.

• vagrant and puppet security for ssl certificates

  - by Sirex

  I'm pretty new to vagrant, would someone who knows more about it (and puppet) be able to explain how vagrant deals with the ssl certs needed when making vagrant testing machines that are processing the same node definition as the real production machines ? I run puppet in master / client mode, and I wish to spin up a vagrant version of my puppet production nodes, primarily to test new puppet code against. If my production machine is, say, sql.domain.com I spin up a vagrant machine of, say, sql.vagrant.domain.com. In the vagrant file I then use the puppet_server provisioner, and give a puppet.puppet_node entry of “sql.domain.com” to it gets the same puppet node definition. On the puppet server I use a regex of something like /*.sql.domain.com/ on that node entry so that both the vagrant machine and the real one get that node entry on the puppet server. Finally, I enable auto-signing for *.vagrant.domain.com in puppet's autosign.conf, so the vagrant machine gets signed. So far, so good... However: If one machine on my network gets rooted, say, unimportant.domain.com, what's to stop the attacker changing the hostname on that machine to sql.vagrant.domain.com, deleting the old puppet ssl cert off of it and then re-run puppet with a given node name of sql.domain.com ? The new ssl cert would be autosigned by puppet, match the node name regex, and then this hacked node would get all the juicy information intended for the sql machine ?! One solution I can think of is to avoid autosigning, and put the known puppet ssl cert for the real production machine into the vagrant shared directory, and then have a vagrant ssh job move it into place. The downside of this is I end up with all my ssl certs for each production machine sitting in one git repo (my vagrant repo) and thereby on each developer's machine – which may or may not be an issue, but it dosen't sound like the right way of doing this. tl;dr: How do other people deal with vagrant & puppet ssl certificates for development or testing clones of production machines ?

• Authenticating Linked Servers - SQL Server 8 to SQL Server 10

  - by jp2code

  We have an old SQL Server 2000 database that has to be kept because it is needed on our manufacturing machines. It also maintains our employee records, since they are needed on these machines for employee logins. We also have a newer SQL Server 10 database (I think this is 2008, but I'm not sure) that we are using for newer development. I have recently learned (i.e. today) that I can link the two servers. This would allow me to access the employee tables in the newer server. Following the SF post SQL Server to SQL Server Linked Server Setup, I tried adding the link. In our SQL Server 2000 machine, I got this error: Similarly, on our SQL Server 10 machine, I got this error: The messages, though worded different, probably say the same thing: I need to authenticate, somehow. We have an Active Directory, but it is on yet another server. What, exactly, should be done here? A guy HERE<< said to check the Security settings, but did not say what else to do. Both servers are set to SQL Server and Windows Authentication mode. Now what?

• Using AddEncoding x-gzip .gz without actual files

  - by STATUS_ACCESS_DENIED

  With Apache (2.2 and later) how can I achieve the following. I want to transparently compress using GZip encoding (not plain Deflate) the output when a certain file is queried with its name plus the extension .gz, where the .gz version doesn't physically exist on disk. So let's say I have a file named /path/foo.bar and no file foo.bar.gz in the folder to which the URI /path maps, how can I get Apache to serve the contents of /path/foo.bar but with AddEncoding x-gzip ... applied to the (non-existing) file? The rewrite part appears to be easy, but the problem is how to apply the encoding to a non-existent item. The other way around also seems to be simple as long as the client supports the encoding. Is the only solution really a script that does this on the fly? I'm aware of mod_deflate and mod_gzip and it is not what I'm looking for - at least not alone. In particular I need an actual GZIP file and not just a deflated stream. Now I was thinking of using mod_ext_filter, but couldn't bridge the gap between rewriting the name of the (non-existent) file.gz to file on one side and the LocationMatch on the other. Here's what I have. RewriteRule ^(.*?\.ext)\.gz$ $1 [L] ExtFilterDefine gzip mode=output cmd="/bin/gzip" <LocationMatch "/my-files/special-path/.*?\.ext\.gz"> AddType application/octet-stream .ext.gz SetOutputFilter gzip Header set Content-Encoding gzip </LocationMatch> Note that the header for Content-Encoding isn't really needed by the clients in this case. They expect to see actual GZIP files, but I want to do this on-the-fly without caching (this is a test scenario).

• How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

  - by Travesty3

  I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

• Windows Server 2008 R2 install reboots unexpectedly during "Completing installation" phase

  - by knda

  I am attempting to install Windows Server 2008 R2 onto a Cisco UCS C201 M2 rack mounted server but am having major difficulties and wondering if anyone has some insight or items they could recommend for me to look at to get this one resolved. Installation is being attempted via the Cisco remote console (using CIMC's Virtual dvd-rom).. following the first phase of Setup where the installation files are copied to the target hard drive, then a reboot occurs to load Setup from the HDD, mid-way in the "Completing Installation" phase the system then reboots unexpectedly. System configuration Cisco UCS C201 M2 (2RU rack mounted server) 16GB RAM, 2x 73GB 15K SAS, 4x 300GB 10k SAS Add-on cards - Intel quad-port GigE card (no fibre channel cards) Storage - LSI MegaRAID SAS 9261-8i. onboard SATA is disabled (no SATA drives connected) KVM - Belkin No physical DVD-ROM.. :( I have... Run memtest86+, no RAM faults Disabled/enabled SATA support (BIOS) Attempted install from USB DVD-ROM, no effect Attempted unattended install scripted via Cisco Configuration Manager DVD provided Removed Belkin KVM in case that was causing drama Discovered that the Cisco website is "awesome" for searching for PDFs/Drivers cough, reverted back to Google Downloaded latest LSI drivers from LSI's site and used during Server 2008 install checked Windows ISO against checksum's from MS site checked Windows ISO by using it for an install in a VM Running out of ways to troubleshoot this as I am not sure how to enable any sort of 'verbose' mode during the setup process. Next step I have planned is to remove the Intel NIC and try the installation again.. Edit: Problem was the "Cisco INTEL QUAD PT GBE" (1000/PT) .. will have to see if this card is faulty or if it's just drivers.. thanks for the help.

• Why can't I connect to computers on my network using our external IP address?

  - by Kivin

  My home network is serviced by an ADSL line. The modem is in bridged mode. The router performs the PPPoE. Three computers are connected to the router: two wired Windows 7 boxes and a Ubuntu Linux box over wifi. The computers are hosting various forms of services including FTP and HTTP. The router has port forwarding mapped from the relevant ports to the reserved IP addresses for the computers. If I attempt to connect to a server inside the network, such as ftp://67.xx.xxx.xxx from inside the network, the request times out. However if I connect using the internally mapped address, such as ftp://192.168.0.100, all is well. This is a nuisance for setting up software, especially on the laptop which needs to be able to phone home from anywhere, and I just don't have enough expertise with networking to know why this is occurring to even have a clue whether it can be solved or not. edit: It should be noted that the servers can be accessible outside the network - say, at the starbucks across the street - perfectly fine, using the ISP provided address and the appropriate port.

• "The directory name is invalid" when trying to install drivers in Windows 7 via Device Manager

  - by Luke

  First off, this computer is not mine, it's a customer's system. Having said that... The hard drive was moved to a new motherboard, CPU, RAM combo, and booted up fine. Customer puts in driver CD, drivers won't load. He brings it into me. Under Device Manager for Windows 7 x64, I see lots of PCI to PCI bridge, one SMBus Controller, and about 20 Unknown Devices. Greeeeeat... So I start with the SMBus driver directly from the Asus website for the motherboard (P8H77-M Pro). If I install from the setup program, it tells me to reboot, then it starts the install. It gets half way through the setup, then fails (An unknown error occurred. Setup will exit). When I try to point to the folder from Device Manager, it starts copying files for the driver, even presents me with the proper name of the device, but says that an error has occurred there as well: The directory name is invalid. Doing some Googling, I saw that many people had this issue with Vista. K, Vista and 7 are similar, maybe the solutions are the same... But they aren't. I tried: Copying the entire driver folder and setup utility to the Program Files folder and running it / selecting it in DM Downloading another set of drivers in case this one is corrupt Disabling UAC Deleting and recreating the %WINDIR%\TEMP folder Removing all references to previous hardware that I could find, even in Device Manager's hidden mode So far, nothing has worked. A wipe and reload will be out of the question

• Vista failing to load after apparently being repaired

  - by Joomaz

  Hi, I apologise if I'm a litre vague and can give more info if needed. My vista machine has been working fine until today when I tried booting it. Vista loads showing the loading bar then goes to a black screen with the cursor on which you can move. It then remains like this for several minutes, during this time the computer doesn't sound like it's doing much, it is relatively quiet. Finally the welcome screen appears. It stays on this for several minutes again and the computer reboots. This keeps happening and the machine fails to load in safe mode - the same happens. I booted the pc with the vista disk in and ran repair your computer and used the system repair. It took about 20 minutes saying it was repairing damaged giles. I booted the pc again and the same happened. I loaded the pc with yeh vista disk again and chose repair my computer again. System repair seemed to run automatically this time and agian it did the same. I rebooted and the problem persisted. I then tried system restore to a few days ago. After half a hour as it finished it said it failed due to a portion being corrupt. I am really not sure what to do now. Any advice appreciated!

• Can't login via ssh after upgrading to Ubuntu 12.10

  I have an Ubuntu 12.04LTS instance on AWS EC2 and I upgraded it to 12.10 following the instructions at https://help.ubuntu.com/community/QuantalUpgrades. After upgrading I can no longer ssh into my VM. It isn't accepting my ssh key and my password is also rejected. The VM is running, reachable, and SSH is started.

• Kerberos service on win2k dc will not start following disk failure

  - by iwilson68

  Hi, I have a win2k (mixed mode domain) with 4 DCS. One of these also acts an exchange 2000 server which uses 2 logical volumes from an MSA 2000 array. AD etc is stored on local drives. We experienced a problem last week when the raid array fell back to a redundant controller and this temporarily meant that the two logical drives were not visible to the server for around 5 minutes and a couple of reboots. The log records these Events as Type: Warning Event Source: Disk Event Category: None Event ID: 51 Date: 06/11/2009 Time: 11:46:23 User: N/A Computer: server1 Description: An error was detected on device \Device\Harddisk1\DR1 during a paging operation. Following these problems, the server “kerberos Key Distribution” service refuses to start with an “error.31 a device attached to the system is not functioning”. All other automatic start services (including net logon) are running and there are no DNS issues etc. All devices are also functioning but the two logical MSA disks are now numbered in the Windows Disk Management MMC as 2 and 4 and I suspect that they may have previously been identified as disks 1 & 2 and perhaps windows still sees this as an ongoing failure?? Replication has not been affected but obviously there are many audit failures in the security log relating to users and workstations presumably linked to the Kerberos issue. Attempting to manually start the kerberos service generates the following in the System Log. Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7023 Date: 09/11/2009 Time: 09:46:55 User: N/A Computer: Server1 Description: The Kerberos Key Distribution Center service terminated with the following error: A device attached to the system is not functioning. DCDIAG passes all tests except “Advertising” and “Services” which I believe relate directly to the failure of Kerberos only. Any advice would be appreciated.

• DNS Resolution doesn't work after uninstalling Cisco VPN & Deterministic Network Enhancer in Win 7

  - by Craig M

  I just upgraded my home PC to Windows 7 Ultimate 32 bit. After trying various methods to get the Cisco VPN client to work, I gave up and decided to just run it in XP mode. The last steps I tried were in this article ( http://social.technet.microsoft.com/Forums/en-US/w7itproappcompat/thread/d880dfe5-7f44-4955-8620-2a9355d8ea8b/ ) After that, I uninstalled the Cisco client and rebooted. I uninstalled the Deterministic Network Enhancer and rebooted again. Both uninstalled successfully, but now I'm not able to resolve any DNS. The only way I can resolve DNS is to reinstall the DNE, reboot, and uninstall the DNE. Then I am able to resolve DNS lookups until I reboot again. Once it's rebooted, no more DNS. Any ideas? Edit: I completely forgot I'd asked this question until harrymc posted his answer. I've since found out that to fix this problem, I need to disable my Local Area Connection and re-enable it. Once I do that I have no trouble making network connections until the next time I reboot at which point I repeat the process. It's annoying, but manageable since I reboot very infrequently.

• Ubuntu: Getting rid of a mimetype entry

  I have a pesky mimetype entry that I can't seem to get rid of. Here is the current situation: xdg-mime query filetype myfile.mfe application/pesky Using assogiate I have found out the information about this mime type entry (but can't delete it there).

• Cisco Catalyst 3750 connected to Cisco ASA 5505 and dropping packets

  (Cross posted from Super User per suggestion there) At the office, I have inherited a network that I am still trying to fully comprehend. I have a problem today with a new connection between: A port on a Cisco Catalyst 3750 [WS-C3750G-48TS-S running C3750-IPSERVICESK9-M version 12.2(53)SE1] A port on a Cisco ASA 5505 [ASA Software version 8.3(2)] The 3750 is home to a Vlan that has a few ports assigned to it. interface Vlan3 description Internal network (172.18.160.0/24) ip address 172.18.160.1 255.255.255.0 I have a host (outside of my control) that needs to be in this VLAN (i.e it must have an address 172.18.160.something/24) that also needs to access the Internet. To accomplish this, I ran a link from the Catalyst (Gi1/0/13) to the ASA (Ethernet 0/5). I configured the Catalyst port like so: interface GigabitEthernet1/0/13 description To ASA, 172.18.160.69 switchport access vlan 3 switchport mode access speed 100 duplex full I configured the ASA like so: interface Vlan1 nameif inside security-level 100 ip address 172.18.160.69 255.255.255.0 interface Ethernet0/5 speed 100 duplex full Then I plugged the host into Ethernet 0/4 on the ASA and instructed its owner to make its default gateway 172.18.160.69. I made a NAT rule in the ASA and set up some rules, and it's able to access the Internet without issue. However, I noticed that the Catalyst reports a ton of packets being dropped toward the ASA. Catalyst3750#show interfaces GigabitEthernet 1/0/13 | include counters|drops Last clearing of "show interface" counters 00:28:13 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 136909347 This is a huge number of drops, since there's not much traffic on this VLAN at all. I tried these things: Make sure speed and duplex agree on both sides (100 Mbps / Full) Set no cdp enable on the Catalyst Gi10/13 Set no keepalive on the Catalyst Gi10/13 Checked for excessive CPU usage on both Checked for excessive traffic on both Am I missing something? Any help would be appreciated.

• Cleaning a proxy/phishing trojan from Windows XP computer

  - by i-g

  I am trying to remove an interesting trojan from a Windows XP computer. It manifests itself as a phishing page (screenshot linked) that appears after the user tries to log on to eBay. So far, I haven't found any other web sites that are affected. As you can see, the trojan intercepts browser connections (all installed browsers are affected) and injects this phishing page. The address looks like it's ebay.com, but HTTPS verification doesn't work (no lock icon or green bar in Firefox.) At some point, Trojan.Dropper appeared on the computer. I removed it with Malwarebytes Anti-Malware. Although it reappeared several times, it seemed to be gone after I booted into Safe Mode and did a full system scan with MBAM. Now, however, a different trojan has appeared on the machine; I suspect it was installed by Trojan.Dropper. So far, MBAM, Ad-Aware, and Spybot S&D have been unable to remove it. I've looked for it in the HijackThis log but haven't found anything conclusive. Has anyone run across a trojan like this before? Where would I start looking for it to remove it manually? Thank you for reading.

• Delay NTP Initialisation, Cisco 877W, IOS 12.4(24)T1

  - by Mike Insch

  I have a Cisco 877W which I'm using for my home ADSL connection (and as a refresher in Cisco IOS). I've got a working config in-place with my PPPoA connection coming online correctly, and VLANs and other settings configured as I want them, but I can't crack the NTP configuration. For NTP, I have the following defined ntp server 0.uk.pool.ntp.org source Dialer0 ntp server 1.uk.pool.ntp.org source Dialer0 ntp server 2.uk.pool.ntp.org source Dialer0 ntp server 3.uk.pool.ntp.org source Dialer0 This setup works fine when issued in Global Configuration Mode when the Dialer0 interface (ATM0.1) is up. The configuration fails at startup though: Translating "1.uk.pool.ntp.org"...domain server (208.67.222.222) (208.67.220.220) ntp server 1.uk.pool.ntp.org source Dialer0 ^ % Invalid input detected at "^" marker. This is repeated for the other servers defined. Obviously the DNS lookup for the server(s) fails because the DNS servers cannot be accessed because the external interface is not yet online. Is there a way to delay the NTP configuration until afte the Dialer0 interface is fully initialised? Can the NTP commands be triggered by the Line Protocol on the Dialer0 interface transitioning to the up state? Alternatively, can the NTP commands be delayed for 5 minutes after the router has finished initialising? Any advice, or pointers to useful documentation or examples gratefully received ...

• Windows XP, Preference menu's hidden for many programs

  - by Jestep

  I don't know when this started happening, but it has been several months since I first noticed it. Basically, when I go to a preferences menu of some programs, the preferences window is completely hidden, but the program see's it as being open. This prevents me from interacting with the preferences and the actual program. So far I've noticed it on Adobe Illustrator and Netbeans. Illustrator when I select edit - Preferences - An Option. On Netbeans it happens when I right click on a site and select properties. Here's a link to a screen shot after I click on the preferences menu (I don't have enough points to post an image yet): http://www.jestep.com/images/screen-2.jpg. Note that the main workspace is grayed out. I have to hit Escape to close the hidden preferences window. I've tried unstinstalling, completely wiping the registry of any trace of the program and reinstalling. Thought it may have been a multi-monitor issue when I switched from 2 monitors down to 1, but menu's were not on other monitor when I plugged one back in. I've reset workspaces, windows display, windows performance settings, changed resolution, safe mode, everything I can think of. I cannot figure out what would cause the same problem on completely unrelated software, and I cannot reset it by reinstalling. Any help would be greatly appreciated.

• QNAP NAS 509 (LINUX) - how to unmout busy volume and find physical disk?

  - by Horst Walter

  On my NAS QNAP TS 509 I do have a technical issue. I need to run e2fsck. This works fine for me on md0 (see below), but how can I unmount the busy devices md9 and sda4 in order to do the same. Whenever I try, I fail because the device is busy. [This part is solved, see below] In order to further track down the issue, I'd need to sort out the physical disk to device relationship. How can I find out this, e.g. md0 is a stripped volume on 2 disk (but I need to find out on what physical disk). Remark: As you can easily derive from my questions, I am not a Linux expert, but manage to get along. /dev/ram0 124.0M 94.1M 29.8M 76% / tmpfs 32.0M 80.0k 31.9M 0% /tmp /dev/sda4 310.0M 103.9M 206.1M 34% /mnt/ext /dev/md9 509.5M 39.2M 470.2M 8% /mnt/HDA_ROOT /dev/md0 1.8T 1.4T 444.7G 76% /share/MD0_DATA tmpfs 32.0M 0 32.0M 0% /.eaccelerator.tmp -- Added -- QNAP seems to be based on Busybox. I do not find something like init / telinit / runlevel. At busybox docs it says that I need to run the below. But in /var/service sv is not available. I want to go to single user mode to unmount the devices. # cd /var/service # sv d * # sv u getty* -- Added, thanks A4L -- This QNAP Box runs a special flavor of Linux, so not all SOPs do apply. In my particular case I found a services.sh script, stopping all services. After that the drive could be unmounted. The information passed by A4L is valid and worth reading it, maybe I'll profit from it next time. Links: http://unix.stackexchange.com/questions/19918/umount-device-is-busy and http://unix.stackexchange.com/questions/15024/umount-device-is-busy-why So the unmount issue is solved, still looking for the best option to find the physical to volume mapping.

• IIS 404 custom error

  - by Greg B

  I've deployed an ASP.NET 3.5 app to a 64bit Windows 2003 R2 server. In the web.config I have the following <customErrors mode="RemoteOnly" defaultRedirect="/404/"> <error statusCode="404" redirect="/404/"/> <error statusCode="500" redirect="/500/"/> </customErrors> In the website properties in IIS Manager I have set the 404 and 500 errors to Type = "URL" and the same URLs as in the web.config. I have a wildcard application map to the .NET 2.0 aspnet_isapi.dll with "Verify file exists" turned off. If I try to hit a fake .aspx file I successfully get sent to the 404 page. I belive this is because there is an explicit mapping for .aspx to the .NET DLL. If I try to access a fake directory I simply recieve a plain text response saying: The system cannot find the file specified. It would appear that these requests for directories are not being routed through the .NET pipeline, which is what I would expect (and need) to happen becuase of the wildcard application mapping. Any ideas?
