• Having trouble using psservice and sc.exe between Windows Server 2008 machines

  - by Teflon Mac

  I'm trying to control services on one W2k8 machine from another; no domain just a workgroup. The user account I'm logged in as is an administrator on both machines. I've tried both psservice and sc.exe. These work in a Windows Server 2003 environment but it looks like I need to an extra step or two due to the changed security model in 2008. Any ideas as to how grant permission to the Service Control Manager (psservice) or OpenService (sc)? I tried running the DOS window with "Run As Administrator" and it made no difference. With psservice I get the following D:\mydir>psservice \\REMOTESERVER -u "adminid" -p "adminpassword" start "Display Name of Service" PsService v2.22 - Service information and configuration utility Copyright (C) 2001-2008 Mark Russinovich Sysinternals - www.sysinternals.com Unable to access Service Control Manager on \\REMOTESERVER: Access is denied. In the remote server, I get the following message in the Security Log so I know I connect and login to the remote machine. I assume it then fails on a subsequent authorization step. The logoff message in the security log is just that ("An account was logged off."), so no extra info there. Special privileges assigned to new logon. Subject: Security ID: REMOTESERVER\adminid Account Name: adminid Account Domain: REMOTESERVER Logon ID: 0xxxxxxxx Privileges: SeSecurityPrivilege SeBackupPrivilege SeRestorePrivilege SeTakeOwnershipPrivilege SeDebugPrivilege SeSystemEnvironmentPrivilege SeLoadDriverPrivilege SeImpersonatePrivilege sc.exe is similar. The command syntax and error differs as below but I also see the same login message in the remote server's security log. D:\mydir>sc \\REMOTESERVER start "Registry Name of Service" [SC] StartService: OpenService FAILED 5: Access is denied.

• How to use cyg-wrapper to fork a new tab in win32 gvim

  - by Peter Nore

  I would like to set up an alias in my cygwin .bashrc that translates pathnames unix-to-dos and passes them to windows gvim in a new tab of an existing instance. I am trying to use Luc Hermitte's cyg-wrapper script for running native win32 applications from Cygwin as per this vim tip. Luc's example of how to use his script is: alias vi= 'cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=-c,--cmd,-T,-t,--servername,--remote-send,--remote-expr' I do not understand this example because most of these vim parameters (-c,--cmd,--servername,--remote-send,--remote-expr, etc) require more information, and I have not found any example of how to supply the additional information to cyg-wrapper.sh. For example, calling C:/Progra~1/Edition/vim/vim63/gvim.exe --servername=GVIM --remote-tab-silent file1 & will open file1 in a new tab of existing (or non existing) instance GVIM, but calling gvim --servername accomplishes nothing on its own. Unfortunately, though, the corresponding cyg-wrapper phrase does not work: cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 file1 If ran twice, this actually opens up two instances of gvim; it is as if the servername 'GVIM' is being stripped and ignored. How do you supply a servername to gvim --servername or a .vimrc to gvim -u using cyg-wrapper.sh? Furthermore, why is it that programs must be passed to cyg-wrapper.sh in the relatively obscure "mixed form?" For example, if I try cyg-wrapper.sh "/cygdrive/c/path/to/GVimPortable.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 I get "Invalid switch - "/cygdrive"."

• Performance variation

  - by Ree

  During my time spent working with multiple machines, I have noticed that performance of the same machine doing the same tasks in the same order differs and sometimes the difference is big enough to be noticeable. This applies to all the machines I've owned and/or maintained (old and modern). Some examples (many of them you may have noticed yourself) that sometimes are completed in different time frames: POST OS installation Hardware tests and operations (usually executed within a customized OS such as one of the many DOS variants), HDD tests and "low level" formats Software installation or other tasks (such as benchmarks) within a general purpose OS (Windows, Linux, etc) I can imagine this is caused by the fact that a machine is built with many components having to communicate as a whole and since the mechanical and electronic parts aren't perfect the overhead occurs. In the last example, I assume the OS complexity and concurrently running multiple processes has some additional effect as well. However, I'm wondering if this hardware imperfection and overhead is indeed that high to be humanly noticeable? Maybe there are other factors that are influencial as much or even more? So, in short - why? To emphasize: the difference is noticeable on the same machine performing the same tasks and this applies to ANY machine in my experience. I'm not comparing machine to machine performance.

• How to diagnose disk errors when disk appears to be ok?

  - by Kylotan

  I have a six-month-old 1TB Seagate drive formatted into 2 NTFS partitions, and the disk appeared to be failing with Windows dropping down from UDMA to PIO mode, reporting Delayed Write Errors, and hanging Explorer when browsing directories. My initial suspicion was that the disk was dying. However, on further examination it appears that Ubuntu, which doesn't write to the volume frequently like Windows does, was able to read the disk properly and retrieve all the data intact, saving me from having to use an older backup. Finally, running the Seatools DOS diagnostic reported that the disk has no problems, ie. SMART errors and no bad sectors, apparently. This, in combination with the relative youth of the disk, suggests that something else is broken. The cable? The PSU? The integrated disk controller? But what would be a good way to diagnose the problem without risking damaging the data? I intend to extract the disk and try it in an external eSATA enclosure and see if the write errors cease, but in the event of the disk appearing to be fine, I would like to be able to confirm what part of the hardware is actually broken here in order to know just what needs replacing. Are there any good ways to go about this?

• How to write files in specific order?

  - by Bernie

  Okay, here's a weird problem -- My wife just bought a 2014 Nissan Altima. So, I took her iTunes library and converted the .m4a files to .mp3, since the car audio system only supports .mp3 and .wma. So far so good. Then I copied the files to a DOS FAT-32 formatted USB thumb drive, and connected the drive to the car's USB port, only to find all of the tracks were out of sequence. All tracks begin with a two digit numeric prefix, i.e., 01, 02, 03, etc. So you would think they would be in order. So I called Nissan Connect support and the rep told me that there is a known problem with reading files in the correct order. He said the files are read in the same order they are written. So, I manually copied a few albums with the tracks in a predetermined order, and sure enough he was correct. So I copied about 6 albums for testing, then changed to the top level directory and did a "find . music.txt". Then I passed this file to rsync like this: rsync -av --files-from=music.txt . ../Marys\ Music\ Sequenced/ The files looked like they were copied in order, but when I listed the files in order of modified time, they were in the same sequence as the original files: ../Marys Music Sequenced/Air Supply/Air Supply Greatest Hits ls -1rt 01 Lost In Love.mp3 04 Every Woman In The World.mp3 03 Chances.mp3 02 All Out Of Love.mp3 06 Here I Am (Just When I Thought I Was Over You).mp3 05 The One That You Love.mp3 08 I Want To Give It All.mp3 07 Sweet Dreams.mp3 11 Young Love.mp3 So the question is, how can I copy files listed in a file named music.txt, and copy them to a destination, and ensure the modification times are in the same sequence as the files are listed?

• copSSH and cygwin - Can't use windows style paths

  - by DrFredEdison

  I setup copSSH on one of my windows servers, and within the copSSH bash shell, I can't seem to use windows-style paths to remove and copy files. If I do try, I get the following: $ /bin/cp -r C:/Domains/_temp/collage_push/* C:/Domains/collage/ cygwin warning: MS-DOS style path detected: C:/Domains/_temp/collage_push/ Preferred POSIX equivalent is: /cygdrive/c/Domains/_temp/collage_push/ CYGWIN environment variable option "nodosfilewarning" turns off this warning. Consult the user's guide for more details about POSIX paths: http://cygwin.com/cygwin-ug-net/using.html#using-pathnames I have created a windows environment variable CYGWIN set to nodosfilewarning. It has no effect. I added export CYGWIN=nodosfilewarning to my .bashrc and doing a echo $CYGWIN in my ssh session confirms it is indeed getting set; yet again, it has no effect finally, I noted that when not doing my own export that CYGWIN contains "nontsec binmode" (no quotes), so I tried: export CYGWIN="nodosfilewarning nontsec binmode" in my .bashrc and still no dice. Older versions of CopSSH didn't have this issue. How can I actually override this error? I have a lot of scripts that already use windows-style paths, and I'd rather not change them if possible.

• Wiping Deleted Directory Entries and Defragmenting Directories

  - by Synetech inc.

  Hi, I have seen plenty of apps that wipe free space on a disk (usually by creating a file that is as big as the remaining space) or defragment a file (usually by using the MoveFile API to copy it to a new contiguous area). What I have not seen however is a program that wipes the deleted directory entries. That is, when a file is deleted, its information (name, dates, etc.) remain in the directory, but are simply marked as empty. That leaves all kinds of information in a directory entry, and also wastes space since (at least on FAT drives), the directory may be using several clusters. For example, if a directory once had a lot of files, it will be expanded to use another cluster which could be anywhere on the disk. This means that the directory is fragmented, and may be using more clusters than needed, possibly with 100’s of unused (ie, “deleted file”) entries between active files. Does anyone know of a program that can defragment/consolidate directories (ie, wipe unused entries, and move active entries together)? (I would really rather not have to resort to writing my own yet again.) Thanks a lot. EDIT Sorry, I should have said, Windows and/or DOS, for FAT*/NTFS.

• BIOS corrupted? How to proceed? Acer Travelmate 290

  - by dtlussier

  I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

• Does a Windows 7 dvd only have one language?

  - by user326639

  I'm a Dutch developer living in Spain. I recently composed a new computer from new parts and I installed Windows 7 Professional 64 bit (OEM) on it. On the web site of the on-line shop there was a note saying "language: Spanish". Because my English is quite a bit better than my Spanish, but mainly because it is much easier to find information on the web in English, I want my OS to be in English. I asked the on-line shop if they also sold the UK version of Windows 7 but they assured me that "all Windows 7 versions are multi-language". With the installation of XP a few years ago, I remember that I was offered the option English or Spanish while the installation process was still in the DOS-like (non-graphical) screen. While installing Windows 7, I did not see any non-graphical screen and the first time I was asked about the language, was in a drop-down list that contained only Spanish. I know about the language pack possibility of Windows 7, but this is not available on Professional. Even if I had Ultimate, I don't know if it would be possible to install Windows in Spanish, and then add English as a second language from a language pack. I get the impression that English has to be the base-language. Furthermore, I am a bit sceptical until I'd see it in action. What happens with shortcuts (i.e. Select All: ctrl-a in English / ctrl-e in Spanish, and what about logging messages in Event Viewer, etc) So can anybody tell me how it works with languages in Windows 7? Have I been misinformed by the computer shop? Could it be that OEM versions of Windows are single language an a full installation is not?

• Font for Wine that supports the entire character set of the Win32 Console?

  - by Brian Campbell

  I would like to be able to display in the Wine console all characters that the Win32 console can display. I've written a small test program to print out all 8-bit characters: #include <stdio.h> int main(int argc, char *argv[]) { int i, j; for (i = 0; i <= 0xF0; i+=0x10) { for (j = i; j <= i + 0x0F; ++j) printf("%2x:%c", j, (char)j); printf("\n"); } getchar(); return 0; } Under Wine, the best I can do so far is using Andale Mono: While this is what I see on Windows Server 2008: Is there anywhere I can legally download a font that will allow me to view all of those characters under Wine? edit I've found a set of DOS fonts that includes a CP437 font, which should cover the character set I'm interested in. However, even if I install this font, wineconsole doesn't seem to recognize it. Is there any way I can get wineconsole to use this font, or convert this font to a format that wineconsole can use? Or is there any way I can extract fonts from DOSEMU for use in Wine? Oh, and I should probably mention that I'm on Mac OS X 10.6.2, installing Wine via MacPorts, using the wine-devel package. more information I have tried installing some console fonts that should cover the full character set as Mac OS X fonts (such as the NewDOS font listed above, and a font I tried converting from the fonts supplied by DOSEMU). Wine does not seem to pick up on new fonts installed in Mac OS X. Is there a way to register new fonts I've installed with Wine? Would manually editing the system.reg file that seems to contain font mappings work, or is there something else I'd need to do? bump Bounty ends soon, I'm still looking for an answer for this. Does anyone use the Wine console for complex text user interfaces?

• OS X Hard drive recovery

  - by Adam

  I am trying to recover data from a bad Seagate 1TB hard drive in a 2010 iMac. One day the iMac wouldn't boot (stuck at gray screen on startup). I removed the hard drive from the iMac and connected it to a MacBook using a 3.5" HDD to USB adapter. The hard drive wouldn't mount but it did display in Disk Utility that that there were 2 partitions on the disk. I tried to run Disk Warrior and it showed thousands of errors but still wouldn't mount. At this time the hard drive only show one partition in Disk Utility. Next I tried putting the hard drive in a desktop PC and running Spin Rite - which then gave me several division overflow errors (even with running Spin Rite with a newer version of DOS). The SMART status on the drive reports that the drive has had failures and HD Tune referenced the drive had once hit 59 degrees celsius. Disk Utility gives me the following message when running a pair: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. Overall, the hard drive spins up and sounds OK - there are no clicking noises but the hard drive won't mount and displays as a light gray "Macintosh HD" in disk utility. Any tips or advice on how to recover data on this drive would be GREATLY appreciated! Are there any other tools I can try before calling it quits on this drive? Thank you

• I am under DDoS. What can I do?

  - by Falcon Momot

  This is a Canonical Question about DoS and DDoS mitigation. I found a massive traffic spike on a website that I host today; I am getting thousands of connections a second and I see I'm using all 100Mbps of my available bandwidth. Nobody can access my site because all the requests time out, and I can't even log into the server because SSH times out too! This has happened a couple times before, and each time it's lasted a couple hours and gone away on its own. Occasionally, my website has another distinct but related problem: my server's load average (which is usually around .25) rockets up to 20 or more and nobody can access my site just the same as the other case. It also goes away after a few hours. Restarting my server doesn't help; what can I do to make my site accessible again, and what is happening? Relatedly, I found once that for a day or two, every time I started my service, it got a connection from a particular IP address and then crashed. As soon as I started it up again, this happened again and it crashed again. How is that similar, and what can I do about it?

• Better approach to archiving large amounts of original video footage using optical media (DVD/Blu-ra

  - by Rob

  This question is to share my experience as well as ask for suggestions for better methods. Along with 2 friends, I completed the making of a short documentary film in 2006. Clip is at: http://www.youtube.com/mediamotioninvision The film was edited in Adobe Premiere Pro 1.5 on Windows XP. More details and screenshot here: http://www.flickr.com/photos/smilingrobbie/1350235514/ ( note this is not intended to be a plug, we've moved on from this initial learning curve project ;) ) The film is in 4:3 standard definition 720x576 PAL format. As well as retaining the final 30minute film, I wanted to keep all original files that assembled together to make the film. The footage was 83.5Gb So I archived them to over 20 4.7Gb DVD recordables in the original .avi format (i.e. data DVD-ROM format, NOT DVD-Video Mpeg2) Some .avi DV video files were larger than 4.7Gb so I used 7-zip to split them ( here is a guide as to how to do that: http://www.linglom.com/2008/10/12/how-to-split-a-large-file-using-7-zip/ ) To recombine them, a dos shell command like this would do that: copy /b file.avi.* file.avi would do the job, where .* is a wild card to include all the split parts e.g. 001, 002...00n assuming they are all in the same directory path folder. file.avi is the recombined file identical to the original. Later on, I bought a LG BE06 LU10 USB 2.0 Super-multi Blu-ray burner and archived the footage to 2 (two) x 50Gb BD-R DL discs. Again in the original format, written as files to a BD-R in the BD-R BD-ROM UDF format readable by PC/Mac etc, NOT Blu-ray video/film format. This seems to be a good solution for me, because: the archive is in a robust, reasonably permanent, non-volatile medium, i.e. DVD recordable / Blu-ray (debates about stability of optical media organic chemical dye compounds/substrates aside) the format of the archive is accessible by open source tools or just plain Windows Explorer and it's not in a proprietary format I just thought I'd ask folks for their experience on better methods, if such exist.

• Need Info on the Hidden Switch in SET - "/S" How to implement

  - by ttyl

  I am having some problems doing a proper search of "SET/S" or "SET /S" on google and other search providers. The difficulty arises with the SLASH "/", it is commonly used in search engines to add a "nearness" to the search parameter. I have found no way to escape the SLASH when searching for a SLASH. For those on this community, try searching this domain with the two search terms listed above. It just doesn't work, it ends up looking for SET S instead. But I digress. So Im asking the uber-guru's on this board to help me find out about the documentation of /S and how to implement SET /S in a batch file. SET is an internal DOS/cmd commandand allows many things incuding prompting the user, integer math and writing environment strings. in looking at this link: http://www.robvanderwoude.com/os2set.php it appears that the /S is only for OS2 but im thinking that this might not be the case, due to this: http://www.dostips.com/forum/viewtopic.php?t=2704, apparently used with substings and macros. any help is much appreciated

• Why can't I boot in to Windows Recovery Environment to fix my HDD or salvage my data?

  - by Kevin

  I've been trying to get in to WindowsRE to salvage the files on my Sony Vaio laptop after it failed to load Vista (it finally, consistently displays "Error loading operating system" after months of such intermittent failures, usually rectified via restarts or utilizing Startup Repair or CHKDSK from WindowsRE) . The problem is, after successfully accessing it once after this failure (and many times before over the course of the laptop's life), I can no longer get it to load. During the last successful access (right after the failure), I ran startup repair, which itself failed and notified me that the boot sector was corrupt. I attempted to head in to Sony's proprietary recovery tools menu, which is accessible from WindowsRE when it is loaded from the recovery partition or recovery disk, however it hung. I have since been unable to access the recovery environment after restarting, using any of these methods: Access via the recovery partition (pressing F10 on boot) Access via recovery DVD (created using the same computer when it was healthy) Access via a Windows Vista installation DVD All three methods produce the same results: The computer acknowledges the boot attempt The computer successfully gets passed the "Windows is loading files" screen The computer successfully gets passed the Windows loading screen The computer then stalls at a black screen, while showing HDD activity (via indicator light). After a few minutes, the HDD activity ceases, and after a few more minutes, the over sized cursor that is utilized in WindowsRE appears on the black screen. The actual recovery environment, however, never appears, even after leaving the computer in such a state overnight. What is fustrating is that other bootable utilities, such as SeaTools for DOS and MemTest, boot up and run fine. In running perfectly normally, MemTest was able to produce a plethora of errors utilizing my RAM. I'm inclined to believe the RAM's faultiness may causing the WindowsRE booting to fail. Would this be a valid assumption? If I'm not mistaken, booting from external media utilizes the RAM, so such a reason is plausible, assuming my knowledge of bootloading is correct. Other than that, I can't figure out any reason why all the bootable utilities except WindowsRE run fine. Does anyone know what the problem is, or could be? Any solutions?

• Using GUI ftp on Win7 and Vista without additional software

  - by Stephen Jones

  Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

• How can I recover XFS partitions from a formatted HD?

  - by giuprivite

  I deleted the partition table of my HD. I wanted to format another one, but by mistake, I formatted the wrong one. Then I also created some new partition on it. Now I would like, if possible, to recover my old data. The old configuration was this: A primary NTFS partition with Windows, and a secondary partition with four logical partitions: a swap and three XFS partitions (two for Ubuntu and OpenSuSE, and one with the home for both systems). This is the output I get when I run gpart in a terminal: ubuntu@ubuntu:~$ sudo gpart /dev/sdb Begin scan... Possible partition(Windows NT/W2K FS), size(39997mb), offset(0mb) Possible extended partition at offset(39997mb) Possible partition(Linux swap), size(8189mb), offset(39997mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(48187mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(89149mb) Possible partition(SGI XFS filesystem), size(175044mb), offset(130112mb) End scan.

• MySQL Server hitting 100% unexpectedly (Amazon AWS RDS)

  - by Luc

  Please help! We've been struggling with this one for months. This week we upped our RDS instance to the highest performing instance and although the occurrences have reduced, we're still having our DB all of a sudden hit 100%. It comes out of nowhere. Sometimes 2am, sometimes midday. I've ruled out a DOS - our pages access logs have normal traffic I've ruled out memcached suddenly dieing (hits and misses continue as normal). The SHOW PROCESSLIST while we have issues reports about 500 queries in queue. If I kill them off or restart the server, they just keep coming back and then eventually out of knowhere, our server resumes back to normal. Sometimes up to 3 hours. Our bad performing queries take .02 seconds to execute when the server eventually returns back to normal but while we're in this 100% CPU physco phase, those queries never finish executing. Please help!!!!! Anybody know anything about MYSQL query optimization? Could it be the server deciding to use different indexes all of a sudden, which puts it into a spiral?

• How to find the cause of locked user account in Windows AD domain

  - by Stephane

  After a recent incident with Outlook, I was wondering how I would most efficiently resolve the following problem: Assume a fairly typical small to medium sized AD infrastructure: several DCs, a number of internal servers and windows clients, several services using AD and LDAP for user authentication from within the DMZ (SMTP relay, VPN, Citrix, etc.) and several internal services all relying on AD for authentication (Exchange, SQL server, file and print servers, terminal services servers). You have full access to all systems but they are a bit too numerous (counting the clients) to check individually. Now assume that, for some unknown reason, one (or more) user account gets locked out due to password lockout policy every few minutes. What would be the best way to find the service/machine responsible for this ? Assuming the infrastructure is pure, standard Windows with no additional management tool and few changes from default is there any way the process of finding the cause of such lockout could be accelerated or improved ? What could be done to improve the resilient of the system against such an account lockout DOS ? Disabling account lockout is an obvious answer but then you run into the issue of users having way to easily exploitable passwords, even with complexity enforced.

• Fail2Ban adds iptable rules but they are not working?

  - by EApubs

  Fail2Ban just blocked my IP for 3 SSH attempts. It added the iptables rule and I can see it using the "sudo iptables -L -n" command. But I can still access the site and login through SSH! What might be the problem? Is it because im using CloudFlare? I have set Nginx to write the real IPs to the access logs instead of the Cloud Flare IP. Isn't it enough?
