  • Kindle (client) for Mac

    - by doug
    So we're clear, i'm talking bout the client/software version here--ie, that you install on your Mac or PC--not the device. The Kindle client was recently released for the Mac. I bought a couple of Kindle-edition books and i'm reading them using this client. Astonishingly, two features i consider to be more or less essential to any ebook reader are missing in the Kindle client, either that, or i can't find them: (i) text searching; and (ii) highlighting text. First, does anyone know how to access the search feature? I'm aware of the "Go To" button at the top middle of the reader window--the options in that menu when you click the button are: "Cover", "Table of Contents", "Beginning" and "Location." "Location" requires that you type in an integer (but it doesn't correspond to page number--e.g., typing "167" brought me to the table of contents), not a search term. Second, there's a button on the upper right-hand corner of the window "Show Notes and Marks" yet i can't find any way to highlight text. The only kind of "note" or "mark" i have been able to record is to "bookmark" a page by clicking the "bookmark" button also at the top of the window.

  • Regular Windows 7 BSOD with Shrew VPN client

    - by Junto
    The Shrew VPN client appears to be a good alternative to the Cisco VPN Client on x64 Windows 7. However, since installing it I've seen fairly regular BSODs.

Superuser appears to have several recommendations for the Shrew VPN Client as an alternative to the Cisco VPN client on 64 bit machines, so I wondered if anyone here has seen this problem and possibly found a solution to the problem? I've decided to run the VPN client under Windows 7 compatibility mode for the moment (Vista SP2) with administrator privileges to see if it makes a difference. Oddly, the VPN doesn't necessarily need to be connected. I've noticed it when browsing using Google Chrome and Internet Explorer, usually when I open up a new tab. If it carries on I think I'll be forced to shell out the 120 EUR for the NCP Client instead.

  • Windows XP error message: "Windows cannot find 'explorer.exe'"

    - by Meysam
    In Windows XP I can open "My Computer" and see all the hard drives. I can also see the explorer.exe process running among other processes in Task Manager. But after opening "My Computer", when I double click on one of the drives to open it, I get the following error message: Windows cannot find 'explorer.exe'. Make sure you typed the name correctly, and then try again. To search for a file, click the start button, and then click search. Although I could detect and remove several suspicious files using Malwarebytes & Microsoft Security Essentials, the problem still remains. The interesting point is that if I right click on one folder and select Open or Explore from the menu bar, I can open the folder! but if I double click on the folder, it does not open and I get the above error message. How can I fix this problem? Any advice would be appreciated! Update: I formatted the C: drive (NTFS), a deep format, and installed a fresh Windows XP on it. I am not getting this error when I double click on C drive icon anymore. But the same error appears when I double click on other drive names. Maybe I should format them too!

  • Google Chrome doesn't delete my browsing history correctly

    - by Derfder
    I have deleted everything that I could from my browser history: chrome://settings/clearBrowserData I checked everything and select the begining of time Then when I access browsing history: chrome://history/ There is nothing (as I expected), or to be precise No history entries found. The problem is that I still see my specific search url with very specific query I have made a month ago, when I start typing the url of the website into chrome address bar. How is that possible? Where is Google stroing these data. How to get rid off them completely? I want to mention that my autosuggestion options look like this: So, what else should I delete to remove everything from autosuggestions? Right now it has some specific URLs (subpages, pages with very specific search query I have made in a month or so). I have tried restarting Chrome and restarting my computer, but the urls are still in the autosuggestion. Also I am unable to turn off the autosuggestion, even I have unchecked that option in settings. My Google Chrome version is: Version 27.0.1453.116 m (probably the latest) Btw. in Firefox deleting the history works as expected. So, I guess that this has nothing to do with the operating system I am using (Windows 7), but only it's an issue with Chrome itself.

  • Why Ubuntu could treat hosts file so strange?

    - by z4y4ts
    I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.myviacube.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

  • Workstations cannot see new MS Server 2008 domain, but can access DHCP. (solved)

    - by Radix
    The XP Pro workstations do not see the new replacement domain upon boot; they only see their cached entry for the old (server 2003) domain controller. The old_server is not connected to the network. I have DHCP working with the same scope as the old_server. In my "before-asking" search for a solution I came across the following two articles, and I recall doing things as suggested by the articles. http://www.windowsreference.com/windows-server-2008/how-to-setup-dhcp-server-in-windows-server-2008-step-by-step-guide/ http://www.windowsreference.com/windows-server-2008/step-by-step-guide-for-windows-server-2008-domain-controller-and-dns-server-setup/ The only possible issue is: I was under the impression that the domain netbios needed to match the DC's netbios. The DC netbios is city01 while the domain's FQDN is city.domain.org (I think this is mistaken and should have been just domain.org) But, the second link led me to a post which I believe answers my question. I did as they instructed by opening Local Area Connection Properties, then selecting TCP/IPv4 and setting the sole preferred DNS server to the local hosts static IP (10.10.1.1). Search for "Your problems should clear up" for the post I'm referencing: http://forums.techarena.in/active-directory/1032797.htm Have I misunderstood their instructions? I am hoping to reach the point where I can define users and user groups. Also, does TechNet have a single theoretical overview document I could read. I really don't like treating comps as magic. I will be watching this closely and will quickly answer any questions. If I've left anything out it is because I did not know it was needed. PS: I am loath to ask obviously basic questions, but I am tired and wish to fix this before tomorrow. Also, this is my first server installation, thank you for your help.

  • Destroyed user account on OS X with dscl; how to restore? [migrated]

    - by Sam Ritchie
    I was trying to create a new user on my OS X Lion machine, and somehow managed to destroy my own user's account. Here are the steps I took; hopefully someone here can recognize what I did, and maybe identify some way around this. First, I ran these commands: sudo dscl localhost -create /Local/Default/Users/elasticsearch sudo dscl localhost -create /Local/Default/Users/elasticsearch /bin/bash # mistake! sudo dscl localhost -create /Local/Default/Users/elasticsearch UserShell /bin/bash sudo dscl localhost -create /Local/Default/Users/elasticsearch RealName "Elastic Search" sudo dscl localhost -create /Local/Default/Users/elasticsearch UniqueID 503 # MY uniqueID sudo dscl localhost -create /Local/Default/Users/elasticsearch PrimaryGroupID 1000 sudo dscl localhost -create /Local/Default/Users/elasticsearch NFSHomeDirectory /Local/Users/elasticsearch The big mistake I made here was using "503", which was my user's UniqueID. Immediately my shell username changed to "elasticsearch". I fiddled around, tried to change the current user with sudo su -u sritchie, but this didn't work. On restart, only the "Elastic Search" user was available. I logged into the Lion Recovery partition and reset the root password. After logging in as root and checking on the terminal, I made the remarkable discovery that my home folder was totally empty. I deleted the elasticsearch user, but it made no difference. I don't see anything in Deleted Users either. The odd thing is that when I log in now as myself (sritchie) I can see desktop icons with previews. I can even open a few text files from the Downloads folder if I use the dock alias to Downloads. Could this data be hiding somewhere? Any help would be REALLY appreciated! Thanks, Sam

  • Logging into Local Statusnet instance on Apache causes browser to download a file

    - by DilbertDave
    I've installed statusnet 0.9.1 on a Windows Server via the WAMP stack and on the whole it seems to be fine. However, when logging in using IE7 or Chrome the browers invoke a file download, i.e. the File Download dialog is displayed. In IE7 the file is called notice with the content below (some parts starred out): <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/"> <ShortName>Mumble Notice Search</ShortName> <Contact>david.carson@*****.com</Contact> <Url type="text/html" method="get" template="http://voice.*****.com/mumble/search/notice?q={searchTerms}"></Url> <Image height="16" width="16" type="image/vnd.microsoft.icon">http://voice.*****.com/mumble/favicon.ico</Image> <Image height="50" width="50" type="image/png">http://voice.******.com/mumble/theme/cloudy/logo.png</Image> <AdultContent>false</AdultContent> <Language>en_GB</Language> <OutputEncoding>UTF-8</OutputEncoding> <InputEncoding>UTF-8</InputEncoding> </OpenSearchDescription> In Chrome (Linux and Windows!) the file is called people and contains similar XML. This is not an issue when logging in using FireFox. This is obviously a configuration issue but I'm not having much luck tracking it down. I tested the previous version of Statusnet on an Ubuntu Server VM on our network and it worked fine for months. Thanks In Advance

  • Tool to Save a Range of Disk Clusters to a File

    - by Synetech inc.
    Hi, Yesterday I deleted a (fragmented) archive file only to find that it did not extract correctly, so I was left stranded. Fortunately there was not much space free on the drive, so most of the space marked as free was from the now-deleted archive. I pulled up a disk editor and—painfully—managed to get a list of cluster ranges from the FAT that were marked as unused. My task then was to save these ranges of clusters to files so that I could examine them to try to determine which parts were from the archive and recombine them to attempt to restore the deleted file. This turned out to be a huge pain in the butt because the disk editor did not have the ability to select a range of clusters, so I had to navigate to the start of each cluster and hold down Ctrl+Shift+PgDn until I reached the end of the range (which usually took forever!) I did a quick Google search to see if I could find a command-line tool (preferably with Windows and DOS versions) that would allow me to issue a commands such as: SAVESECT -c 0xBEEF 0xCAFE FOO.BAR ::save clusters 0xBEEF-0xCAFE to FOO.BAR SAVESECT -s 1111 9876 BAZ.BIN ::save sectors 1111-9876 to BAZ.BIN Sadly my search came up empty. Any ideas? Thanks!

  • High load average due to high system cpu load (%sys)

    - by Nick
    We have server with high traffic website. Recently we moved from 2 x 4 core server (8 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 5.x, to 2 x 4 core server (16 cores in /proc/cpuinfo), 32 GB RAM, running CentOS 6.3 Server running nginx as a proxy, mysql server and sphinx-search. Traffic is high, but mysql and sphinx-search databases are relatively small, and usually everything works blazing fast. Today server experienced load average of 100++. Looking at top and sar, we noticed that (%sys) is very high - 50 to 70%. Disk utilization was less 1%. We tried to reboot, but problem existed after the reboot. At any moment server had at least 3-4 GB free RAM. Only message shown by dmesg was "possible SYN flooding on port 80. Sending cookies.". Here is snippet of sar 11:00:01 CPU %user %nice %system %iowait %steal %idle 11:10:01 all 21.60 0.00 66.38 0.03 0.00 11.99 We know that this is traffic issue, but we do not know how to proceed future and where to check for solution. Is there a way we can find where exactly those "66.38%" are used. Any suggestions would be appreciated.

  • recursive grep started at / hangs

    - by Martin
    I have used following grep search pattern on multiple platforms: grep -r -I -D skip 'string_to_match' / For example on FreeBSD 8.0, FreeBSD 6.4 and Debian 6.0(squeeze). Command does a recursive search starting from root directory, assumes that binary files do not have the 'string_to_match' and skips devices, sockets and named pipes. FreeBSD 8.0 and FreeBSD 6.4 use GNU grep version 2.5.1 and Debian 6.0 uses GNU grep version 2.6.3. On FreeBSD 6.4, last information printed to stderr was "grep: /dev/cuad0: Device busy". After this grep just idles as according to "top -m io -o total" the I/O usage of grep is nonexistent. Same behavior is true under FreeBSD 8.0, but last information sent to stderr is "grep: /tmp/.wine-0: Permission denied" on my installation. In case of Debian, last output to stderr is "grep: /proc/sysrq-trigger: Input/output error". If I check the I/O usage of grep process under Debian, it is following: root@Debian:~# iotop -bp 22439 Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / ^Croot@Debian:~# What might cause this? Is there a way to view which file grep is currently processing in case lsof is not present? I'm able to use lsof under Debian and looks like the problematic file name there is "0xc6b2c230 file struct, ty=0, op=0xc0d34120". I'm not sure what this is.. I'm not able to use lsof or fstat under FreeBSD. PS: I know I could use find utility, but this is not the question.

  • Adding a Printer to my Print Server Failing

    - by Rudi Kershaw
    So, on the Windows Server page I read the following. Step 4: Add Network Printers Automatically Print Management (Printmanagement.msc) can automatically detect all the printers that are located on the same subnet as the computer on which you are running Print Management, install the appropriate printer drivers, set up the queues, and share the printers. To automatically add network printers to a printer server Open the Administrative Tools folder, and then double-click Print Management. In the Printer Management tree, right-click the appropriate server, and then click Add Printer. On the Printer Installation page of the Network Printer Installation Wizard, click Search the network for printers, and then click Next. If prompted, specify which driver to install for the printer. So, I have got to this point, made sure the printer (Canon MP620) is on and correctly plugged into the network. However, when I click "Search the network for printers", the wizard doesn't find it. Now, I can't get any further. Is there anything I could be doing wrong? How should I proceed moving forwards?

  • FTP Upload works from local command line / remote GUI client but not from PHP script

    - by MrOodles
    I originally posted this question at StackOverflow, but I'm beginning to think it's more of a server question. I have installed ProFTPd on an EC2 instance running Ubuntu 10.10. I have managed my proftpd.conf file as well as my server permissions to be able to connect and upload/move files using FTP both remotely using Filezilla, and on the server itself when connecting to 127.0.0.1. The problem I'm running into is when I try to upload/install a file using Joomla's interface. I give Joomla the same login information that I give to Filezilla, and the connection is made in the same fashion. The ftp.log file actually shows that Joomla is able to login to the server: localhost UNKNOWN nobody [17/Jan/2011:14:09:17 +0000] "USER ftpuser" 331 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASS (hidden)" 230 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASV" 227 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "TYPE I" 200 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "STOR /directory/store/location/file.zip" 550 - But it fails when attempting the STOR command. I have traced the problem in the Joomla code to the PHP FTP module. The code (with my trace statements added): if (@ftp_put($this->_conn, $remote, $local, $mode) === false) { echo "\n FTP PUT failed."; echo "\n Remote: $remote ; Local: $local ; Mode: $mode - Either ASCII: ".FTP_ASCII." or Binary: ".FTP_BINARY; echo "\n The user: ".exec("whoami"); JError::raiseWarning('35', 'JFTP::store: Bad response' ); return false; } Trace ouputs: FTP PUT failed. Remote: /directory/store/location/file.zip ; Local: /tmp/phpwuccp4 ; Mode: 2 - Either ASCII: 1 or Binary: 2 The user: www-data And in case you were curious, here is an example of the FTP log when using Filezilla: my_client_ip UNKNOWN nobody [17/Jan/2011:16:45:55 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "MLSD" 226 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "CWD location" 250 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PWD" 257 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PASV" 227 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:07 +0000] "MLSD" 226 3757 my_client_ip UNKNOWN nobody [17/Jan/2011:16:46:37 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "CWD /location" 250 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "STOR file.zip" 226 125317 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "MLSD" 226 497

  • Free, simple, configurable SOCKS5 server

    - by Pooria Azimi
    I've been looking (for the past 6-7 hours) for a fast, free and configurable SOCKS5 server. I haven't found anything that matches my needs. They are either too complicated, too bare-bones or simply buggy as hell. This is (all) I need: I want it to run on Linux (and also OS X, preferably) I want it to listen on localhost:8888 When my app (say wget.. or curl --socks5=localhost:8888) requests http://www.google.com/search?q=asd (or any other url - both http and https), I want it to fetch the page not from google's servers, but from http://localhost:4444/cached?uri=http://www.google.com/search%3Fq%3Dasd. Nothing more! I don't need caching, or anything else. I just want a SOCKS5 server, running locally, which redirects all queries to my own (local) server. It could be written in C, C++, Python, PHP, Perl, Node.js or any other language. I don't care, as long as it supports my (very limited) needs, or I can easily change the source to make it so. Thanks a lot

  • How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

    - by Michael Prescott
    The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

  • Unable to ping gateway via bridge nic

  • Splunk is fantastically expensive: What are the alternatives?

    - by samsmith
    This has been discussed, but it has been several months, so it may be time to revisit it: Earlier discussion RE Splunk alternatives For the record, Splunk rocks. But the pricing is simply beyond what we can consider (When I spoke with Splunk today, the cost for a system to index 5gb/day of data is over $30,000.) That is more than we spend on SQL Server (by a large multiple), more than we spend on a rack of servers (by a multiple), etc. etc. The splunk sales team is correct (that for $30K we get more value and functionality than if we spend the same building our own system), but it doesn't matter. The splunk cost is simply too high (by a multiple). Soooooo, we are looking around! Is anyone out there building a splunk like system? Our basic need: Able to listen for syslog messages on multiple udp ports Able to index the incoming data in an async way Some kind of search engine Some kind of UI An API to the search engine (to embed in our console) We currently need to index 3-5gb/day, but need to be able to scale to 10gb/day or more. We do not need a lot of history (30 days is fine). We use Windows 2008 and 2003 servers. Thanks for your thoughts!

  • How can I get Haproxy to not log local requests?

    - by coneybeare
    I am trying to clean out some of the log clutter from my machines and am starting by removing requests that are generated from the server themselves. I have cache warmers running around the clock and I don't want these polluting the logs. I was able to get apache to stop logging local requests by adding a dontlog for the local IP: SetEnvIf Remote_Addr "RE\.DA\.CT\.ED" dontlog CustomLog "|logger -p local3.info -t http" combined env=!dontlog and now I am looking for something similar to put in a configuration for the Haproxy log. How can I prevent 127.0.0.1 requests from writing to the Haproxy log? UPDATE: 2/15/11 I use the excellent loggly service to pull out logs in the cloud, but I am seeing tons of logs like this: 2011 Feb 15 06:09:42.000 ip-10-251-194-96 http: RE.DA.CT.ED - - [15/Feb/2011:06:09:42 -0500] "HEAD /search/Nevad/predictive/txt HTTP/1.0" 200 - "-" "Wget/1.10.2 (Red Hat modified)" 2011 Feb 15 06:09:42.000 127.0.0.1 haproxy[10390]: 127.0.0.1:58408 [15/Feb/2011:06:09:42] www i-5dd7a331.0 0/0/0/8/8 200 210 - - --NI 0/0/0 0/0 "HEAD /search/Nevad/predictive/txt HTTP/1.1" and I want them gone. This question focuses on how to remove that haproxy log line from writing to the server side log in the first place.

  • Find and Replace String in filenames

    - by shekhar
    I have thousands of files with no specific extensions. What I need to do is to search for a sting in filename and replace with other string and further search for second string and replace with any other string and so on. I.e.: I have multiple strings to replace with other multiple strings. It may be like: "abc" in filename replaced with "def" * String "abc" may be in many files "jkl" in filename replaced with "srt" * String "jkl" may be in many files "pqr" in filename replaced with "xyz" * String "pqr" may be in many files I am currently using excel macro to get the file names in excel and then preserving original names in one column and replacing desired in the content copied in other column. then I create a batch file for the same. Like: rename Path\OriginalName1 NewName1 rename Path\OriginalName2 NewName2 Problem with the above procedure is that it takes a lot of time as the files are many. And As I am using excel 2003 there is limitation on number of rows as well. I need a script in batch like: replacestr abc with def replacestr pqr with xyz in a single directory. Will it be better to do in unix script?

  • OpenLDAP ACLs are not working

    - by Dr I
    First things first, I'm currently working with an OpenLDAP: slapd 2.4.36 on a Fedora release 19 (Schrödinger’s Cat). I've just install the openldap with yum and my configuration is the following one: ##### OpenLDAP Default configuration ##### # ##### OpenLDAP CORE CONFIGURATION ##### include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema pidfile /var/lib/ldap/slapd.pid loglevel trace ##### Default Schema ##### database mdb directory /var/lib/ldap/ maxsize 1073741824 suffix "dc=domain,dc=tld" rootdn "cn=root,dc=domain,dc=tld" rootpw {SSHA}SECRETP@SSWORD ##### Default ACL ##### access to attrs=userpassword by self write by group.exact="cn=administrators,ou=builtin,ou=groups,dc=domain,dc=tld" write by anonymous auth by * none I launch my OpenLDAP service using: /usr/sbin/slapd -u ldap -h ldapi:/// ldap:/// -f /etc/openldap/slapd.conf As you can see it's a pretty simple ACL which aim to allow access to the userPassword attribute to a specific group read only, then to the owner read and write to anonymous requiring auth and refuse the access to everyone else. The problem is: Even using a valid user with correct password my ldapsearch ends with zero informations retrieved from the directory, plus I've got a strange response on the result line. # search result search: 2 result: 32 No such object # numResponses: 1 here is the ldapsearch request: ldapsearch -H ldap.domain.tld -W -b dc=domain,dc=tld -s sub -D cn=user,ou=service,ou=employees,ou=users,dc=domain,dc=tld I did not specify any filter as I want to check that ldapsearch is correctly printing only allowed attribute.

  • Server Recovery from Denial of Service

    - by JMC
    I'm looking at a server that might be misconfigured to handle Denial of Service. The database was knocked offline after the attack, and was unable to restart itself after it failed to restart when the attack subsided. Details of the Attack: The Attacker either intentionally or unintentionally sent 1000's of search queries using the applications search query url within a couple of seconds. It looks like the server was overwhelmed and it caused the database to log this message: Server Specs: 1.5GB of dedicated memory Are there any obvious mis-configurations here that I'm missing? **mysql.log** 121118 20:28:54 mysqld_safe Number of processes running now: 0 121118 20:28:54 mysqld_safe mysqld restarted 121118 20:28:55 [Warning] option 'slow_query_log': boolean value '/var/log/mysqld.slow.log' wasn't recognized.

  • Looking for a real DisplayPort hub/splitter

    - by squircle
    In my search for a new display, I came across the Dell Multi-Monitor Hub MMH11, which seemed to be an alternative to my search for daisy-chainable DisplayPort displays. However, before I cave and spend $179 on this device, I am wondering if this will be similar to other splitting devices where it appears to the computer as one big monitor and the device does the splitting (which I don't want). Or, does this use the packet-based nature of DisplayPort to present two/three separate displays to the computer? Also, would this device work on my MacBook Pro? (I know the Dell site says it's for Windows, but it also says that no driver installation is required. I'd assume since the MBP supports DP 1.2 it would work, but it's better to ask). Thanks! Edit: I've checked out the similar-looking Cirago DisplayPort splitter, but I have extreme doubts as to whether or not it's a genuine displayport splitter, or just another monitor-conglomerate. Their DVI solution looks identical to Dell's, which I'm pretty sure won't do what I want. I also don't want to order this DisplayPort "hub" and find that it doesn't do what I want it to.

  • Best grep-like tool

    - by e-satis
    I do in file search a lot, and used to love grep. Then I learn the existence of egrep, so I switched to benefit from the advanced regexp. Then I discovered the Eclipse search tool. Much easier to use that grep. Then I found ack : fast, easy, powerful. And now I use grin, which is smooth for pythonistas. I know there is also a couple of this kind of tools with a GUI. So what tool do you use, and why do you think it's the best. Practical features generally are : fast to fire and use; speedy processing; automatically ignore useless files; colored output; output lines, filename, context; allow complex regexp; allow a custom filtering and ouput; GUI + command line intergation; let you open an editor from the result set. There are some related posts on SO : http://stackoverflow.com/questions/87350/what-are-good-grep-tool-for-windows http://stackoverflow.com/questions/981601/colorized-grep-viewing-the-entire-file-with-highlighting http://stackoverflow.com/questions/1028107/is-there-some-unix-util-that-will-allow-me-to-grep-multiple-files-with-little-type http://stackoverflow.com/questions/1027906/unix-find-grep-syntax-vs-awk

  • Need Help Scoping a Server to use for study (MCITP Ent Admin + SharePoint 2010)

    - by AVFamily76
    i need to study for mcitp, but i also need to study for sharepoint 2010 i have a poweredge 1850 with two single-core CPUs + two 73G drives - it kills me on electricity, so don't want to use it, and it won't do VT, but it could be one of three boxes for a lab that's cheap, but will cost a lot on electricity i was thinking . . . OPTION #1 Opteron 4170 HE (50 watt chip), 6-core, only two-bills ($200), but the board's are $250, so that's an $800 box, then get another box to dual-boot Win7/Hyper-V on the cheap...? OPTION #2 Used Quad - but how many VM's that are really banging away could it run at same time? (Server 2008r2, SQL 2008r2, Search Server) OPTION #3 Study from books and just get one box that can run two VM's at same time, even if slowly. the last time i had and used a home lab was five years ago when i had a DC, SQL, Exchange and business app box, that's where i got my server skills was just banging on it for four years, but didn't read any books, so now i have to get certified and know the material, and just am not sure how much attention i should pay to the box i use versus the studying time and reading. sorry it's a subjective question, and am obviously open to all sorts of abuse here, but hope you can tell me also how many VM's i can run at the same time given what they'll be doing (SQL and SharePoint FAST search server are resource hungry) thanks!
