• What is shrink_slab, and why is it showing up in /var/log/messages?

  - by Steve Kehlet

  I'm investigating some application issues on a Linux system and noticed this around the time of the most recent problem, but not close enough to be definitively related: Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-155456000 Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-157859400 Jun 7 17:51:49 localhost kernel: shrink_slab: nr=-157833400 Jun 8 06:20:23 localhost kernel: shrink_slab: nr=-284172800 What is this? Googling isn't helping, I get that it's something with VM, but why is it suddenly showing up in /var/log/messages? Edit: I take it it's showing this because the number of pages it could free ("nr") is negative. Which is presumably a bad thing. I found patches for newer kernels that display a more useful message to this effect. Still not sure what this means though, or what I need to do about it.

• Where can I find a good, tab-less privacy filter for my monitor?

  - by KeyStroke

  Hi, I have an ASUS laptop with a 14" monitor (12" by 7" to be more specific), and I've been looking for a decent privacy filter that I can use with for, yet I couldn't find any. The problem with the filters I've found is that they all use those ugly "tabs" that you have to stick on the sides of your monitor in order to slip the filter in. I'm looking for ones that are like HP privacy filter, where parts of it goes under the frame of the monitor to hold it in place. Too bad HP doesn't sell filters that fit my screen. So, any idea where I can get a good privacy filter? Your help is so much appreciated

• Zfs Drive config on FreeNas

  - by Martyn

  Couple of related questions. Background: I have a stock of drives lying about that I want to use in a HP Proliant Microserver which has a 4 slot SAS cage with FreeNas. I don't want to spend any more on parts. 1) With Zfs and RAIDZ, how bad would it be to mix 2 x 1TB Seagate Barracudas with 2 x 1TB WD Green drives. The latter Green drives are I believe only 5,400 RPM, but I can't find that info for sure. 2) Which would be better, the above mis-match in a RAIDZ or 2 x 3TB Seagate Barracuda in a mirror. Considering both performance and data security 3) I have a spare 250GB drive and a spare SATA slot (for optical drive, not sure on speed) as well, would that be a performance gain to use that for the ZIL and L2ARC (over just using the main drives). Thanks in advance.

• In place SQL 2008 upgrade vs. Side by side?

  - by Jim

  I have a SQL 2005 Std edition server with 5 databases in production, 4 db's are used by web-based apps the 5th is a desktop application. My question is should I perform an in-place upgrade or a side-by-side by creating an sql2008 instance on the same box? The machine is a VM on vmware and I'm planning on taking a snapshot before the upgrade and having a 'blackout' window during the upgrade so that I could roll back to the snapshot if things go really bad. Any previous experience and advice is appreciated.

• Server 2003 slow share.

  - by G V

  I am running an 03 box with shares active. When uploading to the share, the speed is average. About 15-20 mbps.. But when you think about it, it is bad because it is a direct connection to a couple machines. When uploading to another server the connection speed is twice that of the direct storage. When uploading s massive folder, 250 GB, the upload will start as normal, but as it progresses it drops in speed. Now it is sitting at around 2-7 Mbps. Any ideas on how i can boost the transfer rate? On a side note, the download speed is great. It is a speed that you would expect from this setup, the main problem is uploading and what is causing the extreme slowness in speeds. Any help would be great.

• Verify linux user passwords

  - by zero_r

  Hi there I got a linux server that has several dozen users. I also have the cleartext password for every user (i know - bad security). I would like to know if the passwords are correct. Since the users are all ftp users and have the nologin shell, I cannot just write a script to check if login works. How can I do a local check on passwords? Script output could look like this: $ check_userpw < user_pw_list.txt user1 ok user2 ok user3 mismatch! user4 ok Thanks

• Problem with Win7 connecting to Internet

  - by Lucas

  Hello, I have had Windows 7 for about a year now and for the first four months it worked perfectly. But for the last 8 months it has been horrible. It will connect to the Internet for about 5 minutes and then just lose connection. It will reconnect in about 5 minues but then it just keeps disconnecting. I ran a virus scan about 2 weeks ago and I found a Trojan on my PC which I removed and dealt with. It was fine after that but now for these last couple days it has been just as bad as before. I think a virus is causing this but I will read any suggestions and tips to help me solve this problem. Thank you. PC DETAILS: OS: WIndows 7 Home Premium 64-Bit- System Model: Aspire M5802- Processor: Intel Core 2 Quad CPU- Memory: 8192MB RAM- Graphics Card: NVIDIA GeForce GT 220

• Graphing/charting of CPU utilisation [on hold]

  - by Peter

  So nagios can be good at graphing particular resource utilisation or other metrics, but I'm looking for a tool that can output a chart or other graphical representation of how much CPU time/CPU utilisation /all/ services on a server are currently consuming. I think New Relic could probably achieve this to an extent, but I was wondering if there was a popular open source app used for this. In case I am explaining this in a bad way, my actual problem is that I have a shared server with suexec enabled (ie. httpd cgi running under multiple user accounts). I'd like to know which users are using the most CPU during periods of the day.

• iPhone Docked Playing Through PC, Buzzing.

  - by DrFloyd5

  Hi. I have an iPhone that I fit into an Apple dock. There is an audio cable from dock into the line in on my sound card. My headphones are plugged into the line out. I get this really quite buzz that is fairly constant, but changes as the iphone "does stuff". It's not so bad when the music is playing. But when it stops I get the buzz, so I can't really use my headphones as "noise cancellation." It doesn't help to change my volume sliders on the PC. Any ideas? Thanks in advance.

• Good bitmap fonts with big sizes and unicode support

  - by bitonic

  I really like bitmap fonts for programming/terminal. As far as I know there are two bitmap fonts with good unicode support: Unifont Fixed The problem is that I have a really high resolution screen, and they're both too small. Fixed does include a large size (10x20) but it looks really bad (it's basically always bold, and bold is a different face). Are there any other bitmap fonts with unicode support and large sizes? Terminus is the only font with a decent size but it doesn't have good unicode support. Having good coverage for mathematical symbols would be enough, since that's what I need.

• D Link DSL G624T Router will work wirelessly but not via cable

  - by Andy Fensome

  I have a D Link router which works in providing a wireless internet connection for my main PC and secondary notebook. I have been advised that the internet connection to the main pc will be better if I wire the router directly to the PC. I have tried this and can not get a connection. I just keep getting the message network cable unplugged. I have had the ethernet adaptor checked out on the pc and the cable is good ( also checked out). Anything I can do or do I have a bad router. I have tried the cable in all 4 ports and the message is still the same.

• solr administration

  - by devrick0

  Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

• Deny IIS6 web request based on URL parameters?

  - by user21146

  I've got a legacy app running a third-party ecommerce system under IIS6. Some spammers recently discovered a bad security vulnerability in one of the store's forms, which are allowing them to send arbitrary emails from our system. Unfortunately, this store "feature" is built into the default.aspx page's code-behind and I have no way to disable it without shutting down the store. How can I filter out URL request with a given querystring parameter? ie, I want to filter out requests to: http://www.mysite.com/store/?id=SendSpam based on the "SendSpam" string.

• Web Server Setup

  - by gustyaquino

  Hello, In my workplace, we want to implement your own web server for at leat 100 Apache/PHP/MySQL web pages. My boss is opposed to hiring skilled personnel, he think we can do ourselves. Currently, we are working with hostgator reseller account. I chose CentOS as the operating system, but I don't know the best hardware solution. HP, Dell ? What about the setup on these platforms? Thanks. PS: sorry for my bad english Edit: The purpose of this migration isn't related to performance issues. But independence.

• Turn off write barriers on ext4 whiche FS is mounted

  - by user462982

  I am doing some IO intensive DB imports that run for several days now and the IO performance has dropped tremendously over times. The DB data files (log files) are on an ext4 formatted logical volume which is mounted with default options (did not specify something special in fstab). Since I just learned that ext4 enables write barriers by default: Q: Is there some way to disable write barriers online (i.e. while the file system is in use), because I cannot interrupt the import and don't want to restart it again. I am aware that write barriers might not be the only thing impeding performance it is a bad idea to have write barriers disabled on journalling file systems if data safty is important (e.g. on a production system)

• Firewall blocks FTP PASV response

  - by harper

  I have an FTP server that supports passive server mode (using PASV command). This works fine with Windows XP. When I want to access this server from Windows Vista or Windows 7 with firewall enabled I experience an immediate connection shutdown. A reset packet is sent to the server, and the socket is signaled that the server has reset the connection (which is not true). The problem disappears when the firewall is disabled. Connections to other FTP servers work correctly. The difference is that the server's response to PASV does not enclose the address field with parentheses. This is legal as documented in RFC-959 and RFC-1132. How can I configure the firewall to stop this bad behavior?

• How do I make stunnel verify a clients certificate?

  - by unixman83

  NOTE: The title is misleading. Please correct it if you know a better title. What I want to know is how do I create the SSL keys / certificates needed for this. Hi. I am using stunnel to authenticate RDP (Remote Desktop) and I need to verify that a client possesses the proper credentials. So people cannot brute force into the machine. I am also using a bad (outdated) version of RDP that has security vulnerabilities, so stunnel is a must. I will preshare the necessary .pem's between machines. What are the openssl commands I need to create the right .pem files on both the client and on the server? What files need to be shared?

• SSD RAID 5 or 10?

  - by Kyle

  I have a few extra SSD drives (I know its rare but this has actually happened). I figured since I have almost 500 GB in SSD's I might as well replace all of my standard HDD's with them. I currently have a RAID 5 setup and enjoy the the speed and redundancy with 10k RPM drives. Should I bother to put my SSD's in RAID 5? I have not heard of anyone doing this and have no idea how it is going to work out. The loss of space doesn't really bother me since I have a 2 TB NAS with all my media on it. Does anyone have experience with putting solid state drives in a RAID 5. If RAID 5 is a bad idea has anyone had experience with a RAID 10? is it possible to stripe the SSD's and provide redundancy with standard HDD's?

• How to point subdomain to a nameserver?

  - by vonconrad

  I've got an old crusty WHM/cPanel server which I'm trying to get rid of. I've got a new setup on shared hosting which is much cheaper in the long run. The problem is that there are a bunch of websites on the server whose domains I don't have access to. They're currently pointing to name servers of my domain (ns.mydomain.com), but the new provider has their own name servers (ns.provider.com) which I have to use instead. My initial idea was to set up a CNAME to point my name server to my provider's: ns.mydomain.com CNAME ns.provider.com, but I read in this question that this would be a bad idea. The accepted answer suggests using an A record instead, and I want to make sure how this would work. Assuming ns.provider.com has an IP address of 123.123.123.123, is it just a matter of doing ns.mydomain.com A 123.123.123.123? Is there any way the provider could block those requests as the name server domain technically doesn't belong to them?

• Windows XP Map drive failed

  - by bajohns

  Greetings, I have a Windows Web Server 2008 VPS and two client machines. One is a Windows 7 box and the other XP. I configured one folder as a share on the 2008 box and attempted to mount it on each of the clients. The catch is it won't work with XP. Same username/password but I get Access granted on the Win 7 but for XP I get: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Any ideas? If this duplicates any other question please refer me but I cannot seem to find the answer.

• running commands as other users - best method

  - by linuxrawkstar

  When running commands as other users from the command line, what is recommended best practice? In the past I've used sudo like so: sudo -u username command [args] I've been told (with no specific reasons why) that using sudo for this purpose is wrong. I'd like to know why. Is there some "best way" to accomplish this? For example, I've also used the su command like so: su username - -c "command [args]" I can't imagine why either of these methods would be "bad". Your thoughts?

• How to remove .htaccess virus? [closed]

  - by bleepingcrows

  Possible Duplicate: My server's been hacked EMERGENCY First time posting so bear with me please! My friend's site has been hacked and the .htaccess file (which I really know nothing about) has been injected with a malicious redirect that forces search engines to the see the site as a "harmful website." If you look at the .htaccess file you can see it's Russian or at least ends in .ru. Seeing as I know very little about this stuff, I simply tried to restore the good .htaccess file back with his host. This doesn't work as the virus just recreates the infected .htaccess file. When I searched through the rest of his directories, I can see the same bad .htaccess file in most of the folders. I can't seem to help him get rid of this virus.

• Fastest security check of file tree on NFS

  - by fungs

  I am currently experiencing very bad performance using the following on an NFS network folder: time find . | while read f; do test -L "$f" && f=$(readlink -m $f); grp="$(stat -c %G $f)"; perm="$(stat -c %A $f)"; done Question 1) Within the loop permissions are checked using the variables grp and perm. Is there a way to lower the amount of disc I/O for these kind of checks over the network (e.g. read all meta data at once using find)? Question 2) It seems like the NFS isn't tuned very well, the same operation on a similar network link via SSHFS take only one third of the time. All parameters are auto-negotiated. Any suggestions?

• Poor disk performance with high disk capacity usage

  - by GoldenNewby

  I've heard numerous times in the web hosting industry that using "too much" disk space on a drive is bad for performance. Is this just a myth? Can someone explain why this is an issue, even in a situation where the amount of IO done to the drive would be the same at 10% as it would be at 90%? I'm especially curious in the case of virtual servers. If I set up 10 Logical volumes as the virtual disks for some VMs, is it going to run better if I "waste" 20% of the disk space?
