• Disaster Recovery Discovery

  - by Rodney Landrum

  Last weekend I joined several of my IT staff on a mission to perform a DR test in our remote CoLo center in a large South East city of the US. Can I be more obtuse? The goal was simple for me as the sole DBA in a throng of Windows, Storage, Network and SAN admins – restore the databases and make them work. There were 4 applications that back ended to 7 SQL Server databases on 4 different SQL Server instances. We would maintain the original server names, but beyond that it was fair game. We had time to prepare so I was able to script out or otherwise automate the recovery process. I used sp_help_revlogin for three of the servers, a bit of a cheat actually because restoring the Master database on the target DR servers was the specified course of action according to the DR procedures ( the caveat “IF REQUIRED” left it open to interpretation. I really wanted to avoid the step of restoring Master for a number of reasons but mainly because I did not want to deal with issues starting SQL Services afterward. Having to account for the location of TempDB and the version conflicts of the resource DBs were just two of the battles I chose not to fight. Not to mention other system database location problems that might arise and prevent SQL from starting.  I was going to have to restore all of the user databases anyway, so I would not really gain any benefit, outside of logins, for taking the time to restore the source Master database over the newly installed one on the fresh server. What I wanted was the ability to restore the Master database as a user database, call it Master_Mine, from a backup on the source system and then use that restored database to script the SQL Logins and passwords on the DR systems. While I did not attempt this on the trip, the thought stuck in my mind and this past week I succeeded at scripting user accounts and passwords using only a restored copy of the Master database. Granted there were several challenges to overcome.  Also, as is usual for any work like this the usual disclaimers apply:  This is not something that I would imagine Microsoft would condone or support and this was really only an experiment for me to learn if it was even possible. While I have tested the process with success, I do not know that I would use this technique in a documented procedure because future updates for SQL Server will render this technique non-functional. I thought at first, incorrectly of course, that I could use sp_help_revlogin on a restored copy of the master database I named Master_Mine.   Since sp_help_revlogin uses system schema objects, sys.syslogins and sys.server_principals, this was not going to work because all results would come from the main Master database. To test this I added a SQL login via SSMS, backed up Master, restored  it as Master_Mine, and then deleted the login.  Even though the test account I created should presumably still be in the Master_Mine database, I should be able to get to it and script out its creation with its password hash so that I would not need to know the password, but any applications that stored that password would not have to be altered in the DR scenario. They would just work as expected. Once I realized that would not work I began looking deeper.  Knowing that sys.syslogins and sys.server_principals are system views, their underlying code should be available with sp_helptext, right? They were. And this led me to discover the two tables sys.sysxlgns and sys.sysprivs, where the data I needed was stored. These tables existed in both the real Master and the restored copy, Master_Mine.  I used this information to tweak the sp_help_revlogin stored procedure to use these tables instead to create the logins cursor used in sp_help_revlogin. For the password hash,  sp_help_revlogin uses the function LoginProperty() which takes a user name and option ‘passwordhash’ to return the hash for the user. Unfortunately, it requires the login to exist in the Master database. This would not work. So another slight modification I had to make was to pull the password hash itself (pwdhash from sys.sysxlgns) into the logins cursor and comment out the section of sp_help_revlogin that uses LoginProperty. Instead, I pass the pwdhash value as the variable @PWD_varbinary to the sp_hexadecimal stored procedure which is also created by and used within the code provided by Microsoft in the link above for sp_help_revlogin. The final challenge: sys.sysxlgns and sys.server_principals are visible only within a Dedicated Administrator Connection (DAC) query window in SSMS or within SQLCDMD.  To open a DAC connection you have to be logged in on the SQL Server itself, via RDP in my case,  and you preface the server name in the query connection with ADMIN:, so that the server connection looks like ADMIN:ServerName. From there you can create the modified stored procedure in the restored copy of a Master database from a source system as whatever name you like, and then run the modified stored procedure. I named my new stored procedure usp_help_revlogin_MyMaster. Upon execution I was happy to see the logins and password hashes that I needed to apply from the source Master database without having to restore over the new Master system database and without the need to access the original server (assuming it was down due to whatever disaster put it in that state). You will note that I am not providing full code samples here of the modifications. I will say that it was a slight bit of work and anyone who needed to do this for whatever reason, could fairly easily roll their own solution with the information provided herein.  My goal, as I said was to prove that this could be done and provide another option if required to ease the burden of getting SQL Servers up and available in an emergency situation where alternatives may be more challenging or otherwise unavailable.

• Why does my Messaging Menu code not work when split into functions?

  - by fluteflute

  Below are two python programs. They're exactly the same, except for one is split into two functions. However only the one that's split into two functions doesn't work - the second function doesn't work. Why would this be? Note the code is taken from this useful blog post. Without functions (works): import gtk def show_window_function(x, y): print x print y # get the indicate module, which does all the work import indicate # Create a server item mm = indicate.indicate_server_ref_default() # If someone clicks your server item in the MM, fire the server-display signal mm.connect("server-display", show_window_function) # Set the type of messages that your item uses. It's not at all clear which types # you're allowed to use, here. mm.set_type("message.im") # You must specify a .desktop file: this is where the MM gets the name of your # app from. mm.set_desktop_file("/usr/share/applications/nautilus.desktop") # Show the item in the MM. mm.show() # Create a source item mm_source = indicate.Indicator() # Again, it's not clear which subtypes you are allowed to use here. mm_source.set_property("subtype", "im") # "Sender" is the text that appears in the source item in the MM mm_source.set_property("sender", "Unread") # If someone clicks this source item in the MM, fire the user-display signal mm_source.connect("user-display", show_window_function) # Light up the messaging menu so that people know something has changed mm_source.set_property("draw-attention", "true") # Set the count of messages in this source. mm_source.set_property("count", "15") # If you prefer, you can set the time of the last message from this source, # rather than the count. (You can't set both.) This means that instead of a # message count, the MM will show "2m" or similar for the time since this # message arrived. # mm_source.set_property_time("time", time.time()) mm_source.show() gtk.mainloop() With functions (second function is executed but doesn't actually work): import gtk def show_window_function(x, y): print x print y # get the indicate module, which does all the work import indicate def function1(): # Create a server item mm = indicate.indicate_server_ref_default() # If someone clicks your server item in the MM, fire the server-display signal mm.connect("server-display", show_window_function) # Set the type of messages that your item uses.

• PowerShell and SMO – be careful how you iterate

  - by Fatherjack

  I’ve yet to have a totally smooth experience with PowerShell and it was late on Friday when I crashed into this problem. I haven’t investigated if this is a generally well understood circumstance and if it is then I apologise for repeating everything. Scenario: I wanted to scan a number of server for many properties, including existing logins and to identify which accounts are bestowed with sysadmin privileges. A great task to pass to PowerShell, so with a heavy heart I started up PowerShellISE and started typing. The script doesn’t come easily to me but I follow the logic of SMO and the properties and methods available with the language so it seemed something I should be able to master. Version #1 of my script. And the results it returns when executed against my home laptop server. These results looked good and for a long time I was concerned with other parts of the script, for all intents and purposes quite happy that this was an accurate assessment of the server. Let’s just review my logic for each step of the code at the top. Lines 1 to 7 just set up our variables and write out the header message Line 8 our first loop, to go through each login on the server Line 10 an inner loop that will assess each role name that each login has been assigned Line 11 a test to see if each role has the name ‘sysadmin’ Line 13 write out the login name with a bright format as it is a sysadmin login Line 17 write out the login name with no formatting It is quite possible that here someone with more PowerShell experience than me will be shouting at their screen pointing at the error I made but to me this made total sense. Until I altered the code, I altered lines 6 and 7 of code above to be: $c = $Svr.Logins.Count write-host “There are $c Logins on the server” This changed my output to look like this: This started alarm bells ringing – there are clearly not 13 logins listed So, let’s see where things are going wrong, edit the script so it looks like this. I’ve highlighted the changes to make Running this code shows me these results Our $n variable should count up by one for each login returned and We are clearly missing some logins. I referenced this list back to Management Studio for my server and see the Logins as below, where there are clearly 13 logins. We see a Login called Annette in SSMS but not in the script results so I opened that up and looked at its properties and it’s server roles in particular. The account has only public access to the server. Inspection of the other logins that the PowerShell script misses out show they too are only members of the public role. Right now I can’t work out whether there is a good reason for this and if it should be expected behaviour or not. Please spend a few minutes to leave a comment if you have an opinion or theory for this. How to get the full list of logins. Clearly I needed to get a full list of the logins so set about reviewing my code to see if there was a better way to iterate through the roles for each login. This is the code that I came up with and I think it is doing everything that I need it to. It gives me the expected results like this: So it seems that the ListMembers() method is the trouble maker in my first versions of the code. I would have expected that ListMembers should return Logins that are only members of the public role, certainly Technet makes no reference to it being left out in it’s Login.ListMembers details. Suffice to say, it’s a lesson learned and I will approach using it with caution in future circumstances.

• Ops Center 12c - Update - Provisioning Solaris on x86 Using a Card-Based NIC

  - by scottdickson

  Last week, I posted a blog describing how to use Ops Center to provision Solaris over the network via a NIC on a card rather than the built-in NIC.  Really, that was all about how to install Solaris on a SPARC system.  This week, we'll look at how to do the same thing for an x86-based server. Really, the overall process is exactly the same, at least for Solaris 11, with only minor updates. We will focus on Solaris 11 for this blog.  Once I verify that the same approach works for Solaris 10, I will provide another update. Booting Solaris 11 on x86 Just as before, in order to configure the server for network boot across a card-based NIC, it is necessary to declare the asset to associate the additional MACs with the server.  You likely will need to access the server console via the ILOM to figure out the MAC and to get a good idea of the network instance number.  The simplest way to find both of these is to start a network boot using the desired NIC and see where it appears in the list of network interfaces and what MAC is used when it tries to boot.  Go to the ILOM for the server.  Reset the server and start the console.  When the BIOS loads, select the boot menu, usually with Ctrl-P.  This will give you a menu of devices to boot from, including all of the NICs.  Select the NIC you want to boot from.  Its position in the list is a good indication of what network number Solaris will give the device. In this case, we want to boot from the 5th interface (GB_4, net4).  Pick it and start the boot processes.  When it starts to boot, you will see the MAC address for the interface Once you have the network instance and the MAC, go through the same process of declaring the asset as in the SPARC case.  This associates the additional network interface with the server.. Creating an OS Provisioning Plan The simplest way to do the boot via an alternate interface on an x86 system is to do a manual boot.  Update the OS provisioning profile as in the SPARC case to reflect the fact that we are booting from a different interface.  Update, in this case, the network boot device to be GB_4/net4, or the device corresponding to your network instance number.  Configure the profile to support manual network boot by checking the box for manual boot in the OS Provisioning profile. Booting the System Once you have created a profile and plan to support booting from the additional NIC, we are ready to install the server. Again, from the ILOM, reset the system and start the console.  When the BIOS loads, select boot from the Boot Menu as above.  Select the network interface from the list as before and start the boot process.  When the grub bootloader loads, the default boot image is the Solaris Text Installer.  On the grub menu, select Automated Installer and Ops Center takes over from there. Lessons The key lesson from all of this is that Ops Center is a valuable tool for provisioning servers whether they are connected via built-in network interfaces or via high-speed NICs on cards.  This is great news for modern datacenters using converged network infrastructures.  The process works for both SPARC and x86 Solaris installations.  And it's easy and repeatable.

• Consumer Oriented Search In Oracle Endeca Information Discovery - Part 2

  - by Bob Zurek

  As discussed in my last blog posting on this topic, Information Discovery, a core capability of the Oracle Endeca Information Discovery solution enables businesses to search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. With search as a core advanced capabilities of our product it is important to understand some of the key differences and capabilities in the underlying data store of Oracle Endeca Information Discovery and that is our Endeca Server. In the last post on this subject, we talked about Exploratory Search capabilities along with support for cascading relevance. Additional search capabilities in the Endeca Server, which differentiate from simple keyword based "search boxes" in other Information Discovery products also include: The Endeca Server Supports Set Search.  The Endeca Server is organized around set retrieval, which means that it looks at groups of results (all the documents that match a search), as well as the relationship of each individual result to the set. Other approaches only compute the relevance of a document by comparing the document to the search query – not by comparing the document to all the others. For example, a search for “U.S.” in another approach might match to the title of a document and get a high ranking. But what if it were a collection of government documents in which “U.S.” appeared in many titles, making that clue less meaningful? A set analysis would reveal this and be used to adjust relevance accordingly. The Endeca Server Supports Second-Order Relvance. Unlike simple search interfaces in traditional BI tools, which provide limited relevance ranking, such as a list of results based on key word matching, Endeca enables users to determine the most salient terms to divide up the result. Determining this second-order relevance is the key to providing effective guidance. Support for Queries and Filters. Search is the most common query type, but hardly complete, and users need to express a wide range of queries. Oracle Endeca Information Discovery also includes navigation, interactive visualizations, analytics, range filters, geospatial filters, and other query types that are more commonly associated with BI tools. Unlike other approaches, these queries operate across structured, semi-structured and unstructured content stored in the Endeca Server. Furthermore, this set is easily extensible because the core engine allows for pluggable features to be added. Like a search engine, queries are answered with a results list, ranked to put the most likely matches first. Unlike “black box” relevance solutions, which generalize one strategy for everyone, we believe that optimal relevance strategies vary across domains. Therefore, it provides line-of-business owners with a set of relevance modules that let them tune the best results based on their content. The Endeca Server query result sets are summarized, which gives users guidance on how to refine and explore further. Summaries include Guided Navigation® (a form of faceted search), maps, charts, graphs, tag clouds, concept clusters, and clarification dialogs. Users don’t explicitly ask for these summaries; Oracle Endeca Information Discovery analytic applications provide the right ones, based on configurable controls and rules. For example, the analytic application might guide a procurement agent filtering for in-stock parts by visualizing the results on a map and calculating their average fulfillment time. Furthermore, the user can interact with summaries and filters without resorting to writing complex SQL queries. The user can simply just click to add filters. Within Oracle Endeca Information Discovery, all parts of the summaries are clickable and searchable. We are living in a search driven society where business users really seem to enjoy entering information into a search box. We do this everyday as consumers and therefore, we have gotten used to looking for that box. However, the key to getting the right results is to guide that user in a way that provides additional Discovery, beyond what they may have anticipated. This is why these important and advanced features of search inside the Endeca Server have been so important. They have helped to guide our great customers to success.

• Postfix - am I sending spam?

  - by olrehm

  today I received like 30 messages within 5 minutes telling me that some mail I send could not be delivered, mostly to *.ru email addresses which I did not send any mail to. I have my own webserver (postfix/dovecot) set up using this guide (http://workaround.org/ispmail/lenny) but adjusted a little bit for Ubuntu. I tested whether I am an Open Relay which I am apparently not. Now there are two possible reasons for the above mentioned emails: Either I am sending out spam, or somebody wants me to think that, correct? How can I check this? I selected one particular address that I supposedly send spam to. Then I searched my mail.log for this entry. I found two blocks that record that somebody from the server connected to my server and delivered some message to two different users. I cannot find an entry reporting that anyone from my server send an email to that server. Does this mean its just some mail to scare me or could it still have been send by me in the first place? Here is one such block from the log (I replaced some confidential stuff): Jun 26 23:23:28 mycustomernumber postfix/smtpd[29970]: connect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: 044991528995: client=mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/cleanup[29974]: 044991528995: message-id=<[email protected]> Jun 26 23:23:29 mycustomernumber postfix/qmgr[3369]: 044991528995: from=<>, size=2198, nrcpt=1 (queue active) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) ESMTP::10024 /var/lib/amavis/tmp/amavis-20110626T223137-28598: <> -> <[email protected]> SIZE=2198 Received: from mycustomernumber.stratoserver.net ([127.0.0.1]) by localhost (rehmsen.de [127.0.0.1]) (amavisd-new, port 10024) with ESMTP for <[email protected]>; Sun, 26 Jun 2011 23:23:29 +0200 (CEST) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) Checking: YakjkrdFq6A8 [195.144.251.97] <> -> <[email protected]> Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: disconnect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) lookup_sql_field(id) (WARN: no such field in the SQL table), "[email protected]" result=undef Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: connect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: 0A1FA1528A21: client=localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/cleanup[29974]: 0A1FA1528A21: message-id=<[email protected]> Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: from=<>, size=2841, nrcpt=1 (queue active) Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: disconnect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) FWD via SMTP: <> -> <[email protected]>,BODY=7BIT 250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21 Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) Passed CLEAN, [195.144.251.97] [195.144.251.97] <> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: YakjkrdFq6A8, Hits: 2.249, size: 2197, queued_as: 0A1FA1528A21, 2882 ms Jun 26 23:23:32 mycustomernumber postfix/smtp[29975]: 044991528995: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.3, delays=0.39/0.01/0.01/2.9, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21) Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 044991528995: removed Jun 26 23:23:33 mycustomernumber postfix/smtp[29980]: 0A1FA1528A21: to=<[email protected]>, orig_to=<[email protected]>, relay=mx3.hotmail.com[65.54.188.110]:25, delay=1.2, delays=0.15/0.02/0.51/0.55, dsn=2.0.0, status=sent (250 <[email protected]> Queued mail for delivery) Jun 26 23:23:33 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: removed Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection rate 1/60s for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection count 1 for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max cache size 1 at Jun 26 23:23:28 I can provide more info if you tell me what you need to know.

• Certificate Trusts Lists in IIS7

  - by BrettRobi

  I am trying to enable mutual authentication for my WebService hosted in IIS7. I have the server side cert setup and working but cannot figure out how to get a Certificate Trust List created and setup in IIS7 so that I can require and validate client side certificates. All of my client side certs are signed by my own root cert so I need to create a CTL that contains just my root cert and then have IIS validate client provided certs against the CTL. Can anyone shed some light on how to do this? IIS6 had a UI for assigning a CTL, but I can find nothing similar in IIS7. Update: I have now successfully used MakeCTL in wizard mode to create a CTL with a Friendly Name. However I don't have adsutil support on my IIS7 box so via other posts elsewhere I am trying to use the 'netsh http add sslcert' command to assign the CTL to my site. Before I could use this command I had to remove the existing SSL cert that was assigned to my site for server authentication. Then in my netsh command I specify the thumbprint of that very same SSL cert I removed, plus a made up appid, plus 'sslctlidentifier=MyCTL sslctlstorename=CA'. The resulting command is: netsh http add sslcert ipport=10.10.10.10:443 certhash=adfdffa988bb50736b8e58a54c1eac26ed005050 appid={ffc3e181-e14b-4a21-b022-59fc669b09ff} sslctlidentifier=MyCTL sslctlstorename=CA (the IP addr is munged), but I am getting this error: SSL Certificate add failed, Error: 1312 A specified logon session does not exist. It may already have been terminated. I am sure the error is related to the CTL options because if I remove them it works (though no CTL is assigned of course). Can anyone help me take this last step and make this work? UPDATE 01-07-2010: I never resolved this with IIS 7.0 and have since migrated our app to IIS 7.5 and am giving this another try. Per the response from Taras Chuhay I installed IIS6 Compatibility on my test server and tried the steps he documented using adsutil.vbs (which can also be found here). I immediately ran into this error: ErrNumber: -2147023584 Error trying to SET the Property: SslCtlIdentifier when running this command: adsutil.vbs set w3svc/1/SslCtlIdentifier MyFriendlyName I then went on to try the next adsutil.vbs command documented and it failed with the same error. I have verified that the CTL I created has a Friendly Name of MyFriendlyName and that it exists in the 'Intermediate Certification Authorities\Certificate Trust List' store of LocalComputer. So once again I am at a dead standstill. I don't know what else to try. Has anyone ever gotten CTL's to work with IIS7 or 7.5? Ever? Am I beating a DEAD horse. Google turns up nothing but my own posts and other similar stories. Update 2/23/10 - I've confirmed with Microsoft that this is a bug with IIS 7.5, but it does work with IIS 7. Check out this link for details: http://viisual.net/configuration/IIS7-CTLs.htm Update 6/08/10 - I can now confirm that KB981506 resolves this issue. There is a patch associated with this KB that must be applied to Server 2008 R2 machines to enable this functionality. Once that is installed all works flawlessly for me.

• Handle filename with spaces inside Bash-script

  - by ifischer

  In my Bash-script i have to handle filenames with spaces. These are the important lines inside my script: mp3file="/media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3" echo "Command: mp3info -x `echo $mp3file`" mp3info -x `echo $mp3file` Unfortunately, the command does not work, because the filename is splitted: mp3info: invalid option -- '\' mp3info: invalid option -- '\' Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\: No such file or directory Error opening MP3: Vol.5\: No such file or directory Error opening MP3: \[MP3PRO\]/01\: No such file or directory Error opening MP3: Nofx\: No such file or directory Error opening MP3: Pump\: No such file or directory Error opening MP3: up\: No such file or directory Error opening MP3: the\: No such file or directory Error opening MP3: Valium.mp3: No such file or directory I also tried to add a custom IFS as i read on some forums: SAVEIFS=$IFS IFS=$(echo -en "\n\b") # Script like above IFS=$SAVEIFS But this way, i'm getting the error Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3: No such file or directory I tried quite a while now but i cannot get my script to work. What is strange is that if i'm running the same command that my script should create manually (echoing it inside my script) on the Shell, it actually works. But not inside my script. Any hints?

• Getting SMB file shares working over a PPTP VPN

  - by Ben Scott

  I'm having issues getting SMB file shares working over a PPTP VPN. The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to the NIC's IP (192.168...), and DHCP on the DrayTek sets the server IP as the DNS. If I create a new VPN connection in Win7, leaving everything as default apart from the server, username, password and domain, I can: ping everything by IP address resolve IPs with nslookup using their fully-qualified name, as in nslookup fileserver.mydomain.local ping machines by fully-qualified name, as in ping fileserver.mydomain.local However if I try to access a file share: within Explorer, I get "Windows cannot access ..." with "Error code: 0x80004005 Unspecified Error", using net use z: \\fileserver.mydomain.local\share, I get "System error 53 has occurred. The network path was not found." If I add the machine name to my HOSTS file I can use the file share, which is my last-ditch workaround, but I have a number of VPN users and would rather a solution that doesn't involve me trying to hand-edit system files on computers half a country away. If I set the WINS server explicitly in the connection's IPv4 settings I don't have to use the FQN to ping the machine, but that doesn't change anything else. EDIT: The PC I'm having the issue on is running Win 7 Home Premium. After more testing I actually have two other PCs that work, one W7HP, one XP Home, and another Vista PC that doesn't work (not tested as much as the others), all four on the same internet connection (behind the same router). All of them were tested with a straight-forward, all defaults, new VPN configuration.

• BIND DNS Master with Zerigo Slaves - BIND won't update the slave servers

  - by Anthony

  I've tried to resolve this myself and have looked through Google and Stack but haven't found the answer I'm looking for. Currently on a VPS server I have BIND DNS installed as a MASTER DNS Server. I use Zerigo's DNS service as SLAVE servers for public use: The Master doesn't receive queries - It's job is to simply create and modify DNS entries locally of which the SLAVE use to serve. Here is an excerpt of the BIND log, I set it to INFO event logging: 14-Apr-2012 23:00:00.234 general: info: received control channel command 'reload' 14-Apr-2012 23:00:00.234 general: info: loading configuration from 'C:\DNS\BIND\etc\named.conf' 14-Apr-2012 23:00:00.234 general: info: using default UDP/IPv4 port range: [1024, 65535] 14-Apr-2012 23:00:00.234 general: info: using default UDP/IPv6 port range: [1024, 65535] 14-Apr-2012 23:00:00.250 general: info: reloading configuration succeeded 14-Apr-2012 23:00:00.250 general: info: reloading zones succeeded 14-Apr-2012 23:16:22.750 xfer-out: info: client 174.36.24.251#47135: transfer of 'ajmakeup.com/IN': AXFR started 14-Apr-2012 23:16:22.750 xfer-out: info: client 174.36.24.251#47135: transfer of 'ajmakeup.com/IN': AXFR ended 14-Apr-2012 23:16:23.015 xfer-out: info: client 68.71.141.22#36212: transfer of 'ajmakeup.com/IN': AXFR started 14-Apr-2012 23:16:23.031 xfer-out: info: client 68.71.141.22#36212: transfer of 'ajmakeup.com/IN': AXFR ended As you can see there is no problem with Zerigo's DNS servers requesting new DNS data, when I force a reload that is; I don't believe, as per the way they are set as SLAVE, that they poll for changes. However the problem is the other way; the MASTER is not updating the SLAVE servers when reload is run (on the MASTER); it is a batch on a 15 minute timer. Below is my NAMED.CONF: key "rndc-key" { algorithm hmac-md5; secret "REMOVED FOR SECURITY"; }; acl "trusted" { 174.36.24.251/32; 68.71.141.22/32; localhost; }; options { version "not currently available"; directory "C:\DNS\BIND\etc"; allow-query { trusted; }; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; logging{ channel simple_log { file "C:\DNS\BIND\logging\bind.log" versions 3 size 5m; severity info; print-time yes; print-severity yes; print-category yes; }; category default{ simple_log; }; }; zone "ajmakeup.com" in { type master; file "c:\dns\BIND\zones\db.ajmakeup.com.txt"; allow-transfer { 174.36.24.251; 68.71.141.22; }; allow-update { none; }; }; Does my problem have something to do with 'allow-query' under options? You will notice that 'allow-transfer' is set explicitly on each DNS zone. In case you need it here is my RNDC.CONF: key "rndc-key" { algorithm hmac-md5; secret "REMOVED FOR SECURITY"; }; options { default-key "rndc-key"; default-server 127.0.0.1; default-port 953; }; server localhost { key "rndc-key"; }; Note: I am using WebsitePanel as my hosting panel and is such why it creates the zone enteries the way it does. Although I know I can change this behaviour, I do not wish to do so nor do I believe is the root of the problem. Thanks for your help.

• Red Hat Yum not working out of the box?

  - by Tucker

  I have a server runnning Red Hat Enterprise Linux v5.6 in the cloud. My project constraints do not allow me to use another OS. When I created the cloud server, I was able to SSH into it and access the shell. I next ran the command: sudo yum update But the command failed. About a month ago I created another server with the same machine image and didn't have that error. Why is it failing now? The following is the terminal output sudo yum update Loaded plugins: security Repository rhel-server is listed more than once in the configuration Traceback (most recent call last): File "/usr/bin/yum", line 29, in ? yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 309, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 178, in main result, resultmsgs = base.doCommands() File "/usr/share/yum-cli/cli.py", line 345, in doCommands self._getTs(needTsRemove) File "/usr/lib/python2.4/site-packages/yum/depsolve.py", line 101, in _getTs self._getTsInfo(remove_only) File "/usr/lib/python2.4/site-packages/yum/depsolve.py", line 112, in _getTsInfo pkgSack = self.pkgSack File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 662, in <lambda> pkgSack = property(fget=lambda self: self._getSacks(), File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 502, in _getSacks self.repos.populateSack(which=repos) File "/usr/lib/python2.4/site-packages/yum/repos.py", line 260, in populateSack sack.populate(repo, mdtype, callback, cacheonly) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 168, in populate if self._check_db_version(repo, mydbtype): File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 226, in _check_db_version return repo._check_db_version(mdtype) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1233, in _check_db_version repoXML = self.repoXML File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1406, in <lambda> repoXML = property(fget=lambda self: self._getRepoXML(), File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1398, in _getRepoXML self._loadRepoXML(text=self) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1388, in _loadRepoXML return self._groupLoadRepoXML(text, ["primary"]) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1372, in _groupLoadRepoXML if self._commonLoadRepoXML(text): File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1208, in _commonLoadRepoXML result = self._getFileRepoXML(local, text) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 989, in _getFileRepoXML cache=self.http_caching == 'all') File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 826, in _getFile http_headers=headers, File "/usr/lib/python2.4/site-packages/urlgrabber/mirror.py", line 412, in urlgrab return self._mirror_try(func, url, kw) File "/usr/lib/python2.4/site-packages/urlgrabber/mirror.py", line 398, in _mirror_try return func_ref( *(fullurl,), **kwargs ) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 936, in urlgrab return self._retry(opts, retryfunc, url, filename) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 854, in _retry r = apply(func, (opts,) + args, {}) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 922, in retryfunc fo = URLGrabberFileObject(url, filename, opts) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1010, in __init__ self._do_open() File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1093, in _do_open fo, hdr = self._make_request(req, opener) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1202, in _make_request fo = opener.open(req) File "/usr/lib64/python2.4/urllib2.py", line 358, in open response = self._open(req, data) File "/usr/lib64/python2.4/urllib2.py", line 376, in _open '_open', req) File "/usr/lib64/python2.4/urllib2.py", line 337, in _call_chain result = func(*args) File "/usr/lib64/python2.4/site-packages/M2Crypto/m2urllib2.py", line 82, in https_open h.request(req.get_method(), req.get_selector(), req.data, headers) File "/usr/lib64/python2.4/httplib.py", line 810, in request self._send_request(method, url, body, headers) File "/usr/lib64/python2.4/httplib.py", line 833, in _send_request self.endheaders() File "/usr/lib64/python2.4/httplib.py", line 804, in endheaders self._send_output() File "/usr/lib64/python2.4/httplib.py", line 685, in _send_output self.send(msg) File "/usr/lib64/python2.4/httplib.py", line 652, in send self.connect() File "/usr/lib64/python2.4/site-packages/M2Crypto/httpslib.py", line 47, in connect self.sock.connect((self.host, self.port)) File "/usr/lib64/python2.4/site-packages/M2Crypto/SSL/Connection.py", line 174, in connect ret = self.connect_ssl() File "/usr/lib64/python2.4/site-packages/M2Crypto/SSL/Connection.py", line 167, in connect_ssl return m2.ssl_connect(self.ssl, self._timeout) M2Crypto.SSL.SSLError: certificate verify failed

• Cisco VPN Client dropping connection

  - by IT Team

  Using Windows XP and Cisco VPN client version 5.0.4.xxx to connect to a remote customer site. We are able to establish the connection and start an RDP session, but within 1-2 minutes the connection drops and the VPN connection disconnects. The PC making the connection is on a DMZ which is NATed to a public IP address. If we move the PC directly onto the internet without being on the DMZ the connection works and we don't encounter any disconnects. We use a PIX 515E running 7.2.4 and don't have any problems with similar setups connecting to other customer sites from the DMZ. The VPN setup on the client side is pretty basic, using IPSec over TCP port 10000. Not sure what device they are using on the peer, but my guess would be an ASA. Any idea as to what the problem would be? Below is the logs from the VPN client when the problem occurs. The real IP address has been changed to: RemotePeerIP. 4 14:39:30.593 09/23/09 Sev=Info/4 CM/0x63100024 Attempt connection with server "RemotePeerIP" 5 14:39:30.593 09/23/09 Sev=Info/6 CM/0x6310002F Allocated local TCP port 1942 for TCP connection. 6 14:39:30.796 09/23/09 Sev=Info/4 IPSEC/0x63700008 IPSec driver successfully started 7 14:39:30.796 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 8 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x6370002C Sent 256 packets, 0 were fragmented. 9 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x63700020 TCP SYN sent to RemotePeerIP, src port 1942, dst port 10000 10 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x6370001C TCP SYN-ACK received from RemotePeerIP, src port 10000, dst port 1942 11 14:39:30.796 09/23/09 Sev=Info/6 IPSEC/0x63700021 TCP ACK sent to RemotePeerIP, src port 1942, dst port 10000 12 14:39:30.796 09/23/09 Sev=Warning/3 IPSEC/0xA370001C Bad cTCP trailer, Rsvd 26984, Magic# 63697672h, trailer len 101, MajorVer 13, MinorVer 10 13 14:39:30.796 09/23/09 Sev=Info/4 CM/0x63100029 TCP connection established on port 10000 with server "RemotePeerIP" 14 14:39:31.296 09/23/09 Sev=Info/4 CM/0x63100024 Attempt connection with server "RemotePeerIP" 15 14:39:31.296 09/23/09 Sev=Info/6 IKE/0x6300003B Attempting to establish a connection with RemotePeerIP. 16 14:39:31.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (SA, KE, NON, ID, VID(Xauth), VID(dpd), VID(Frag), VID(Unity)) to RemotePeerIP 17 14:39:36.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 18 14:39:36.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 19 14:39:41.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 20 14:39:41.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 21 14:39:46.296 09/23/09 Sev=Info/4 IKE/0x63000021 Retransmitting last packet! 22 14:39:46.296 09/23/09 Sev=Info/4 IKE/0x63000013 SENDING ISAKMP OAK AG (Retransmission) to RemotePeerIP 23 14:39:51.328 09/23/09 Sev=Info/4 IKE/0x63000017 Marking IKE SA for deletion (I_Cookie=AEFC3FFF0405BBD6 R_Cookie=0000000000000000) reason = DEL_REASON_PEER_NOT_RESPONDING 24 14:39:51.828 09/23/09 Sev=Info/4 IKE/0x6300004B Discarding IKE SA negotiation (I_Cookie=AEFC3FFF0405BBD6 R_Cookie=0000000000000000) reason = DEL_REASON_PEER_NOT_RESPONDING 25 14:39:51.828 09/23/09 Sev=Info/4 CM/0x63100014 Unable to establish Phase 1 SA with server "RemotePeerIP" because of "DEL_REASON_PEER_NOT_RESPONDING" 26 14:39:51.828 09/23/09 Sev=Info/5 CM/0x63100025 Initializing CVPNDrv 27 14:39:51.828 09/23/09 Sev=Info/4 CM/0x6310002D Resetting TCP connection on port 10000 28 14:39:51.828 09/23/09 Sev=Info/6 CM/0x63100030 Removed local TCP port 1942 for TCP connection. 29 14:39:51.828 09/23/09 Sev=Info/6 CM/0x63100046 Set tunnel established flag in registry to 0. 30 14:39:51.828 09/23/09 Sev=Info/4 IKE/0x63000001 IKE received signal to terminate VPN connection 31 14:39:52.328 09/23/09 Sev=Info/6 IPSEC/0x63700023 TCP RST sent to RemotePeerIP, src port 1942, dst port 10000 32 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 33 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 34 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x63700014 Deleted all keys 35 14:39:52.328 09/23/09 Sev=Info/4 IPSEC/0x6370000A IPSec driver successfully stopped Thank you for any help you can provide.

• Postfix/SMTPD Relay Access Denied when sending outside the network

  - by David

  I asked a very similar question some 4 or 5 months ago, but haven't tracked down a suitable answer. I decided to post a new question so that I can ... a) Post updated info b) post my most current postconf -n output When a user sends mail from inside the network (via webmail) to email addresses both inside and outside the network, the email is delivered. When a user with an email account on the system sends mail from outside the network, using the server as the relay, to addresses inside the network, the email is delivered. But [sometimes] when a user connects via SMTPD to send email to an external address, a Relay Access Denied error is returned: Feb 25 19:33:49 myers postfix/smtpd[8044]: NOQUEUE: reject: RCPT from host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]: 554 5.7.1 <host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]>: Client host rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<my-computer-name> Feb 25 19:33:52 myers postfix/smtpd[8044]: disconnect from host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182] Sending this through Microsoft Outlook 2003 generates the above log.

• DHCPDISCOVER requests from an off-by-one MAC address

  - by Aleksandr Levchuk

  In a Linux DHCP server I'm getting a bunch of these log lines: dhcpd: DHCPDISCOVER from 00:30:48:fe:5c:9c via eth1: network 192.168.2.0/24: no free leases I don't have any machines with 00:30:48:fe:5c:9c and I don't intend to give out an IP to 00:30:48:fe:5c:9c (whatever that could be). I tracked down the server that this is coming from and killed all the DHCP clients that were running but the DHCPDISCOVER requests do not stop. I can prove that this is the sending server by pulling the Ethernet cable - the requests stop. The strange thing is that the sending server only has 2 interfaces which are: 00:30:48:fe:5c:9a 00:30:48:fe:5c:9b What can be the cause of the off-by-one address? Who could be sending the requests?

• Does likewise-open > version 5.4 contain CIFS support?

  - by Ben Andken

  I'm trying to get the CIFS server working in likewise-open. I've found this set of instructions and everything seems to work until I try to connect ([url]http://www.likewise.com/resources/documentation_library/manuals/cifs/likewise-cifs-smb-file-server-guide.html#id2765992):[/url] 1.6. Build and Configure a Standalone Likewise-CIFS Server This section demonstrates how to build and configure a standalone instance of Likewise-CIFS from the command line. The following procedure assumes that you want to set up Likewise-CIFS on a Linux server to share files with Windows computers in a network without Active Directory. This procedure also assumes you know how to build Linux applications from their source code and then install them. Download Likewise-CIFS from its open source git location: $ git clone git://git.likewiseopen.org/ Download, build, and install the following tools. The tools listed are known to work, but earlier or later versions might work as well. Also, instead of downloading the tools, you might be able to install them on your platform with apt-get or some other means. http://ftp.gnu.org/gnu/autoconf/autoconf-2.65.tar.gz http://ftp.gnu.org/gnu/automake/automake-1.9.6.tar.gz http://ftp.gnu.org/gnu/libtool/libtool-2.2.6a.tar.gz http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz gcc --version 3.x or greater Build Likewise-CIFS: $ cd likewise-open $ build/mkcomp --debug all Install Likewise-CIFS: $ sudo su $ cd staging/install-root $ tar cf - . | (cd / && tar xvf -) Make sure Samba is not running: $ /etc/init.d/smb stop Make sure SELinux is either disabled or set to permissive. Make sure the ports required by Likewise are open. For a list of ports that Likewise uses, see the Likewise Open Installation and Administration Guide.

In the following example, substitute the account name that you want for newuser. $ /opt/likewise/bin/lw-add-user --home /home/newuser --shell /bin/bash newuser Successfully added user newuser Enable the user and set the password: $ /opt/likewise/bin/lw-mod-user --enable-user --set-password newuser New Password: ********** Successfully modified user newuser Look up new user's identity as follows. Substitute the value from the command hostname -s for the hostname. Keep in mind that Likewise truncates a hostname longer than 15 characters to the first 15 characters of the string. % id hostname\\newuser uid=2000(HOSTNAME\newuser) gid=1800(HOSTNAME\Likewise Users) groups=1800(HOSTNAME\Likewise Users) context=system_u:system_r:unconfined_t:s0 Make a CIFS directory for the user: mkdir /lwcifs/newuser chown 2000:1800 /lwcifs/newuser From a Windows computer, map the Likewise-CIFS drive share: Computer->Map Network Drive... Folder: \\IP_hostname\c$ Click "Finish" Username: hostname\newuser Password: user_password The last step fails when I try to connect. I've tried with Windows XP Pro and Windows 7 Pro. The rest of the directions only appear to work for version 5.4 (the one that shipped with 10.04). For 12.04, version 6.1 is the only one available and it doesn't appear to have the srvsvc module mentioned in these instructions. Is CIFS support dropped in the 6.1 version of likewise-open?

• Does Apache ever give incorrect "out of threads" errors?

  - by Eli Courtwright

  Lately our Apache web server has been giving us this error multiple times per day: [Tue Apr 06 01:07:10 2010] [error] Server ran out of threads to serve requests. Consider raising the ThreadsPerChild setting We raised our ThreadsPerChild setting from 50 to 100, but we still get the error. Our access logs indicate that these errors never even happen at periods of high load. For example, here's an excerpt from our access log (ip addresses and some urls are edited for privacy). As you can see, the above error happened at 1:07 and only a small handful of requests occurred in the several minutes leading up to the error: 99.88.77.66 - - [06/Apr/2010:00:59:33 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-icons_222222_256x240.png HTTP/1.1" 304 - 99.88.77.66 - - [06/Apr/2010:00:59:34 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_glass_75_dadada_1x400.png HTTP/1.1" 200 111 99.88.77.66 - - [06/Apr/2010:00:59:34 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_glass_75_dadada_1x400.png HTTP/1.1" 200 111 99.88.77.66 - mpeu [06/Apr/2010:00:59:40 -0400] "GET /some/dynamic/content HTTP/1.1" 200 145049 55.44.33.22 - mpeu [06/Apr/2010:01:06:56 -0400] "GET /other/dynamic/content HTTP/1.1" 200 12311 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/jquery-ui-1.7.1.custom.css HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/js/jquery-1.3.2.min.js HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/js/jquery-ui-1.7.1.custom.min.js HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/jquery.tablesorter.min.js HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/date.js HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image1.gif HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image2.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image3.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image4.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image5.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image6.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:56 -0400] "GET /WebRepository/pdfs/image7.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:57 -0400] "GET /WebRepository/pdfs/image8.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:57 -0400] "GET /WebRepository/pdfs/image9.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:57 -0400] "GET /WebRepository/pdfs/imageA.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:57 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_flat_75_ffffff_40x100.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:59 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_highlight-soft_75_cccccc_1x100.png HTTP/1.1" 304 - 55.44.33.22 - - [06/Apr/2010:01:06:59 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_glass_75_e6e6e6_1x400.png HTTP/1.1" 200 110 55.44.33.22 - - [06/Apr/2010:01:06:59 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/images/ui-bg_glass_75_e6e6e6_1x400.png HTTP/1.1" 200 110 11.22.33.44 - mpeu [06/Apr/2010:01:18:03 -0400] "GET /other/dynamic/content HTTP/1.1" 200 12311 11.22.33.44 - - [06/Apr/2010:01:18:03 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/js/jquery-1.3.2.min.js HTTP/1.1" 304 - 11.22.33.44 - - [06/Apr/2010:01:18:04 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/css/smoothness/jquery-ui-1.7.1.custom.css HTTP/1.1" 200 27374 11.22.33.44 - - [06/Apr/2010:01:18:04 -0400] "GET /WebRepository/jquery/jquery-ui-1.7.1.custom/js/jquery-ui-1.7.1.custom.min.js HTTP/1.1" 304 - 11.22.33.44 - - [06/Apr/2010:01:18:04 -0400] "GET /WebRepository/jquery.tablesorter.min.js HTTP/1.1" 200 12795 11.22.33.44 - - [06/Apr/2010:01:18:04 -0400] "GET /WebRepository/date.js HTTP/1.1" 200 25809 For what it's worth, we're running the version of Apache that ships with Oracle 10g (some 2.0 version), and we're using mod_plsql to generate our dynamic content. Since the Apache server runs as a separate process and the database doesn't record any problems when this error occurs, I'm doubtful that Oracle is the problem. Unfortunately, the errors are freaking out our sysadmins, who are inclined to blame any and all problems which occur with the server on this error. Is this a known bug in Apache that I simply haven't been able to find any reference to through Google?

• CoreStore Encryption Error on Mac Lion

  - by Michael

  I am trying to encrypt an external drive using diskutil CoreStorage on Mac Lion 10.7.4. I thought the only requirements were that the drive have GUID partition scheme and Journaled HFS+ file system. I think my drive is configured accordingly but when I type the following command I get an error message back: Michaels-MacBook-Pro:~ Michael$ diskutil cs convert disk2 -passphrase TestPassword Error converting disk to CoreStorage: The given file system is not supported on Core Storage (-69756) Here are the details reported for the drive in question: Michaels-MacBook-Pro:~ Michael$ diskutil list disk2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Test1 499.8 GB disk2s2 Michaels-MacBook-Pro:~ Michael$ diskutil list disk2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Test1 499.8 GB disk2s2 Michaels-MacBook-Pro:~ Michael$ diskutil info disk2s2 Device Identifier: disk2s2 Device Node: /dev/disk2s2 Part of Whole: disk2 Device / Media Name: Test1 Volume Name: Test1 Escaped with Unicode: Test1 Mounted: Yes Mount Point: /Volumes/Test1 Escaped with Unicode: /Volumes/Test1 File System Personality: Journaled HFS+ Type (Bundle): hfs Name (User Visible): Mac OS Extended (Journaled) Journal: Journal size 40960 KB at offset 0xe8e000 Owners: Disabled Partition Type: Apple_HFS OS Can Be Installed: Yes Media Type: Generic Protocol: FireWire SMART Status: Not Supported Volume UUID: 1024D0B8-1C45-3057-B040-AE5C3841DABF Total Size: 499.8 GB (499763888128 Bytes) (exactly 976101344 512-Byte-Blocks) Volume Free Space: 499.3 GB (499315826688 Bytes) (exactly 975226224 512-Byte-Blocks) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: No Ejectable: Yes Whole: No Internal: No I'm a little concerned that the "Partition Type: Apple_HFS" entry is causing the problem, but I don't know how to change that.

• Setting up apache to view https pages

  - by zac

  I am trying to set up a site using vmware workstation, ubuntu 11.10, and apache2. The site works fine but now the https pages are not showing up. For example if I try to go to https://www.mysite.com/checkout I just see the message Not Found The requested URL /checkout/ was not found on this server. I dont really know what I am doing and have tried a lot of things to get the ssl certificates in there right.

• iptable CLUSTERIP won't work

  - by Rad Akefirad

  We have some requirements which explained here. We tried to satisfy them without any success as described. Here is the brief information: Here are requirements: 1. High Availability 2. Load Balancing Current Configuration: Server #1: one static (real) IP for each 10.17.243.11 Server #2: one static (real) IP for each 10.17.243.12 Cluster (virtual and shared among all servers) IP: 10.17.243.15 I tried to use CLUSTERIP to have the cluster IP by the following: on the server #1 iptables -I INPUT -i eth0 -d 10.17.243.15 -j CLUSTERIP --new --hashmode sourceip --clustermac 01:00:5E:00:00:20 --total-nodes 2 --local-node 1 on the server #2 iptables -I INPUT -i eth0 -d 10.17.243.15 -j CLUSTERIP --new --hashmode sourceip --clustermac 01:00:5E:00:00:20 --total-nodes 2 --local-node 2 When we try to ping 10.17.243.15 there is no reply. And the web service (tomcat on port 8080) is not accessible either. However we managed to get the packets on both servers by using TCPDUMP.

Does anyone know which part I missed? Thanks in advance.
