• How to find spyware dll launched using svchost.exe

  - by Sheen

  This weekend I found my PC was possibly infected by some virus or spyware. There is one "svchost.exe -k netsvcs" in my task manager, and it is running under my user name, rather than SYSTEM accounts. There is already another same process with same command line options under SYSTEM account. This user account svchost.exe consistently consumes 50% CPU (1 of 2 cores of my CPU). In Process Explorer, I can see it is started by explorer.exe, instead of services.exe. However, I failed to find its real service dll place in registry or disk. Does anyone know how to find this malicious program?

• How to check if redis master is OK?

  - by e-satis

  On the documentation, they advice the monitor command. But it has a 50% performance penalty for the whole system, and how should I do that ? Whatching the ouput using SSH until I don't see anything ? Let's say I have 3 servers: 1 with a redis master, 1 with a redis slave, and one with my website querying the redis master. How can I, from my website server, make cleany the decision to fallback to the slave by sending the SLAVEOF NO ONE command ? My first step would be to put some kind of timeout check with a simple ping, just to be sure the server is online. But for redis specifically, I have no clue.

• Mcafee Auto-update from UNC path problem

  - by Vicky

  I have a network with 50 computers with no internet access. So instead of updating in each of them using dat file individually I tried to create a shared folder in server, and created a UNC in site repository. I downloaded the file DAT Package For Use with Mcafee AutoUpdate Architect & ePO 3.0 from http://www.mcafee.com/apps/downloads/security-updates/security-updates.aspx. When I try to update it is giving an error Error occurred while downloading file SiteStat.xml. So how fix it?

• How to clean this Dell Precision M6400

  - by Daniel Pratt

  I have (well, ok, my employer has and I use) a Dell Precision M6400 notebook. It's a decent piece of hardware, but I have at least one major gripe: It's a dust and...uh...crumb (I repent! I repent!) magnet! And I cannot seem to exorcise the dust/crumbs from it! There is a strip of metal above the keyboard that is punched full of tiny holes. Well, maybe it's better to describe them as 'pits'. If a sufficiently small particle finds its way into one of those pits, there is only about a 50% that I will manage to get it out. Consequently, there is now a chorus of tiny little particles silently chiding me about eating cookies a cracker whilst I browse the intarwebs. Does anyone have any suggestions about how I could remove these particles from this machine...while still preserving the function of the machine?

• Roaming Profiles: Best Practices

  - by Noah Clark

  I want to setup roaming profiles for about 50 users. What is the best way to go about doing this? What are the best practices. I've read about desktops/my Documents being TOO big. How big is too big? We have a few users who keep a lot of media on their machine to listen to throughout the day. I would imagine they have a few gigs of MP3's in their My Documents folder. How do you deal with this? Thanks!

• Hourly CRON task running more frequently than one hour

  - by Justin

  I have a cron task that calls a special PHP script via wget. Here is the crontab entry: 0 * * * * wget http://www.... It will work perfect for several days, running on the hour. However, after a few days the cron job will start to be called several times an hour. I have never seen CRON drift like this, so I imagine it can't really be a CRON issue. However, the logs of the script that is called clearly show it running several times an hour. Server details: Ubuntu Luci Apache MySQL PHP5 Time is showing correct @ command line Server is setup to sync with a NTP server In order for the script to run it must be passed a unique 50-character hash key in the URL, so this script isn't being called from any other source accidentally. What might cause CRON to drift like this?

• shut down FTP from IIS 6 after <X> failed login attempts

  - by Justin C

  Is there a setting in IIS 6 to turn an FTP site off after a specified number of failed login attempts? It has already been documented on this site that a Windows server sitting on a static IP address can record tens of thousands of failed login attempts a month. One server I maintain has had tens of thousands of attempts made against the FTP port. I have solid passwords in place, so I am not overly concerned. I rarely have to use the FTP, so for the most part I turn it on and off as I need it. Sometimes though I forget to turn it off when I am done, only to find the next day that my EventLog is full of audit failures. I would want to set a high number, in case I just messed up the password. Something like if 50 failed login attempts happen, just turn off the FTP site. Then if I need it later I can just start it again.

• Windows XP failing to set theme correctly on auto-login

  - by Alois Mahdal

  On several testing machines we have, when automatic login (as Administrator) is activated, Windows fails to set theme (Display properties - Themes) correctly. Particularly, even if theme is set to "Windows Classic", visually it's obvious that "Windows XP" is applied (the one with blue title bars and red "X" butons). I have only seen this happen when Auto-login is set--we always use Administrator on XP. Even if I log out and back in manually, theme is set correctly. Apart from logging out and in, it's also possible to reset theme in "Display properties". It does not happen in 100% of the cases, but it's way over 50%. Definitely it's often enough to be annoying. I believe this is a bug in Windows XP. I have never encountered it on other Windows versions. Does anybody know how to avoid this issue once forever? (Or can anybody provide explanation, relevant links, etc.?)

• Best client and server antivirus for 5 user office?

  - by drpcken

  I'm setting up an Active Directory environment for 5 users (very small) and I'm wondering what is the best antivirus for clients (Windows 7) and servers (Server 2008 R2 x64)? I use Symantec Corp at my organization (50+ users) but I think that is overkill for this company. I wanted to use Microsoft Security Essentials for the clients (I use it for home machines and it's the best free AV in my opinion) but I don't think it will work on the Servers (3 servers, PDC, TS, and File). They are behind a Sonicwall TZ 200. What would be the best. Free would be even better. Thank you!

• Is there a way to get the size of Outlook Calendar meeting items?

  - by bethlakshmi

  In our Exchange environment, our company caps the size of an Exchange account at a certain size. That size is the sum of all the exchange related stuff stored on the server - includign both the Inbox and the Calendar. I can tell with the Mailbox properties, Folder Size... window that my Calendar is a good 50% of my account's footprint. Is there any way to get a more detailed view of what meetings in the Calendar are taking up the space? Given the general pattern of incoming mail, it's my belief that 2-5 meetings are responsible for 75% of the memory consumption... I just need to find which meetings are the problem... and with my current calendar, it's a bit like finding a needle in a haystack. Anyone got a trick for this?

• VMware + SQL Server - sqlserver.exe not using both CPU cores

  - by fistameeny

  Hi, I am working on a virtual machine that runs SQL Server Express (as part of Sage Line 50 Manufacturing). The details are as follows: Physical Server (host machine) - Intel Xeon Quad Core 2.1GHz - 4GB RAM - VMDK image stored on RAID-5 500GB SATA drives (7200RPM) - Running Ubuntu 10.04 Server 64 bit - VMware Server 2 Virtual Machine - Windows Small Business Server 2003 - Allocated 2 vCPU's and 2GB RAM - Using 100GB pre-allocated flat VMDK file The problem I have is that there is process that runs in SQL Server that is CPU intensive. On the old physical server that we migrated to the virtual machine from, this would utilise both CPU cores so the sqlserver.exe process would be running 100% on each of the CPU cores. On the virtual machine, it only seems to use one of the two CPU cores, meaning that the process is much slower to run. Question Is there a way to force SQL Server (sqlserver.exe process) to use both of the CPU cores, and distribute it's load between them? Is this a VMware setting that needs changing to allow processes to use both cores?

• VMware postfix server drops connection

  - by nicoX

  Our physical server godzilla forwards mails to our virtuall VMware server b4. They are on the same net. Often connection drops, we can't ping godzilla with our b4. That means mails from godzilla won't reach b4 and the mails will be in handed into the mailq. Sometimes it takes some hours and the issue will auto fix itself, b4 will wake up and the mail will be delivered. Another thing if we remotely ssh into the b4, the b4 will wake up and and receive any mailq mails from godzilla and deliver them. netadmin@b4:/var/log$ arp -a ? (192.168.209.80) at 00:1E:C9:AE:79:9D [ether] on eth0 root@godzilla:/usr/local/bin# arp -a ? (192.168.209.20) at 00:50:56:91:7d:b2 [ether] on eth0

• Terminal Server 2003 Performance Troubleshooting

  - by MikeM

  Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

• Text template or tool for documentation of computer configurations

  - by mjustin

  I regularly write and update technical documentation which will be used to set up a new virtual machine, or to have a lookup for system dependencies in networks with around 20-50 (server-side) computers. At the moment I use OpenOffice Writer with text tables, and create one document per intranet domain. To improve this documentation, I would like to collect some examples to identify areas where my documents can be improved, regarding general structure and content, to make it easy to read and use not only for me but also for technical staff, helpdesk etc. Are there simple text templates (for example for OpenOffice Writer) or tools (maybe database-driven) for structured documentation of a computer configuration? Such a template / tool should provide required and optional configuration sections, like 'operating system', 'installed services', 'mapped network drives', 'scheduled tasks', 'remote servers', 'logon user account', 'firewall settings', 'hard disk size' ... It is not so much low-level hardware docs but more infrastructure / integration information in these documents (no BIOS settings, MAC addresses).

• Slowness on Exchange 2007 Server (network related we think)

  - by Az

  We are seeing some odd behavior out of our exchange 2007 server. I believe it is network related as during the slowness in response from the exchange server. During these times downloading files to server is fraught with connection resets and extreme slow download speeds that are not affecting other servers right on the same subnet with the same gateway and ISP. We have about 50 users at a time using Outlook 2003 from a terminal server not displaying any other signs of slowness, all network slowness is confirmed trying downloads on the exchange server itself. Checked for virus issues, there are none. Checked for hardware issues, none found I am noticing between 200-400 TCPv4 connections established I am seeing around 100k tcpv4(active) connections according to perfmon are these numbers odd? Has anyone run into anything similar? Our server has a gigbabit NIC linked to a gigabit switch using cat6 so I do not believe it is "physical". Thanks!

• Can only bring up one of two interfaces

  - by mstaessen

  I'm having a bizarre issue with my HP Proliant DL 360 G4p server. It has two gigabit ethernet interfaces but I can bring up only one of them. This is starting to freak me out and that's why I turned here. I'm running the x64 ubuntu 11.10 server edition. lshw -c network shows that the second interface is disabled. I have no idea why ans how to enable it. $ sudo lshw -c network *-network:0 description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2 bus info: pci@0000:02:02.0 logical name: eth0 version: 10 serial: 00:18:71:e3:6d:26 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 duplex=full firmware=5704-v3.27b, ASFIPMIc v2.36 ip=10.48.8.x latency=64 link=yes mingnt=64 multicast=yes port=twisted pair speed=100Mbit/s resources: irq:25 memory:fdf70000-fdf7ffff *-network:1 DISABLED description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2.1 bus info: pci@0000:02:02.1 logical name: eth1 version: 10 serial: 00:18:71:e3:6d:25 capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 firmware=5704-v3.27b latency=64 link=no mingnt=64 multicast=yes port=twisted pair resources: irq:26 memory:fdf60000-fdf6ffff If I try to ifup eth1, then I get $ sudo ifup eth1 Ignoring unknown interface eth1=eth1.

But when I add the configuration for eth1, I still can't ifup. $ sudo ifup eth1 RTNETLINK answers: File exists Failed to bring up eth1. I've also tried ifconfig eth1 up but without any result.

• Samba + Centos (Share not working)

  - by mplacona

  I've done this a few times already, but for some reason this time it's not working. I have a folder called ruby (root:root - 0777) on /home/placona I'm trying to see this folder from my WindowsXP box, but keep getting permission denied. I can see the global share though, but whenever I try clicking on the ruby share, it won't let me in. Here's my smb.conf settings: [global] log file = /var/log/samba/samba.%m guest account = nobody netbios name = DEVBOX server string = DEVBOX CENTOS workgroup = WORKGROUP encrypt passwords = yes security = share max log size = 50 [ruby] path = /home/placona/ruby I want to be able to open this folder without using password (hence the guest account = nobody). I tried even with password, but never seems to work. Can anyone spot anything wrong with my settings?

• Quickbooks Error - Can't turn off auto updates

  - by Murtez

  My company uses quickbooks pro 2002 and unfortunately they won't upgrade at this time, the program keeps freezing and giving methe error: This action cannot be completed because this program is busy.. Then asks to switch or retry, I tracked it down to being an issue with IE since it's an old program and can't use the new versions of IE (the program uses IE for it's interface for some STUPID reason). Everyone says to disable auto updates but the problem is that I can't get to the options area to disable the updates (the options area uses IE!!!) so I'm screwed, I have to sit there and click retry 40-50 times several times a day and it's driving me nutz. I've been looking online for days but have not found a solution to this predicament. Is there a way to disable auto updates through the configuration files? Any help is greatly appreciated.

• Problem connecting to MySQL with zend

  - by wheresrhys

  I've set up a virtual host on my local machine (windows xp with xampp installed), have installed zend there and am now trying to connect to the MySQLdatabase. I get the following error message: Message: SQLSTATE[HY000] [2003] Can't connect to MySQL server on ''myhost.com'' (10060) All the tips I've found via google haven't helped. I use kaspersky antivirus and have added port 3306 to the allowed list for MySQL and Apache. I've also pinged myhost.com:3306 and get a response (with ip address 67.63.50.51), though localhost:3306 and 127.0.0.1:3306 aren't found. I've checked that other apps can still access MySQL if the virtual host is pointed at them instead and my non zend apps do work. I guess I have to do something further to the port, or maybe force the app to use a different port, but am not sure how to do either. Any help appreciated.

• How can I make Excel correlate data from two data sets into a single graph?

  - by Tom Ritter

  I have two datasets, one being sparser than the other. They look like this: Data Set 1: 4 50 5 55 6 60 7 70 8 80 Data Set 2: 4 10 6 20 8 30 I have several hundred points instead of this few. I want them in the same graph, the X axis being 4-8, the y axis being 0-100ish, and two lines, one for each data set. What I get is two lines, not correlated at all along the X axis, and the X axis being labeled from one of the two datasets, with the labels being wrong for the other. The smaller data set is one-point-per-tick on the x axis, when I need it to skip ticks and actually line up with the other data set. Not married to excel, willing to try this in something else if it's free.

• Postfix not delivering mails

  - by Sotocan

  Hi all, I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

• How can I disrupt my roommate's BitTorrent?

  - by bob

  We're on a 50 mb/s Comcast connection and our connection right now is coming in under 1.5 mb/s. Our roommate left for a week with BitTorrent running (Azureus client, we think). Our latency is approaching 300 ms. His door is locked up tight, and both his machine and the router for the house are located inside. I've even flipped the power breaker in the house and that barely works for 2 minutes. His laptop keeps on running, and once the cable modem and router come back up and the machine reconnects, the torrents resume in earnest. I've been running nmap and identified his IP on our LAN. Is there anything I can do over the LAN to make his torrents start to fail or slow down?

• Recurring network issues the same time every day.

  - by Peter Turner

  Something has been happening on my company's network at 9:30 every day. I'm not the sysadmin but he's not a ServerFault guy so I'm not privy to every aspect of the network but I can ask questions if follow up is needed. The symptoms are the following : Sluggish network and download speed (I don't notice it, but others do) 3Com phones start ringing without having people on the other end. We've got the following ports exposed to the public for a web server, a few other ports for communicating with our clients for tech support and a VPN. We've got a Cisco ASA blocking everything else. We've got a smallish network (less than 50 computers/vms on at any time). An Active Directory server and a few VM servers. We host our own mail server too. I'm thinking the problem is internal, but what's a good way to figure out where it's coming from?

• Command to determine whether ZooKeeper Server is Leader or Follower

  - by utrecht

  Introduction A ZooKeeper Quorum consisting of three ZooKeeper servers has been created. The zoo.cfg located on all three ZooKeeper servers looks as follows: maxClientCnxns=50 # The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. dataDir=/var/lib/zookeeper # the port at which the clients will connect clientPort=2181 server.1=ip1:2888:3888 server.2=ip2:2888:3888 server.3=ip3:2888:3888 It is clear that one of the three ZooKeeper servers will become the Leader and the others Followers. If the Leader ZooKeeper server has been shutdown the Leader election will start again. The aim is to check if another ZooKeeper server will become the Leader if the Leader server has been shut down. Question Which command needs to be issued to check whether a ZooKeeper server is a Leader or a Follower?
