  • Firewalls: What is the difference between Policy, NAT and Routes?

    - by Jakobud
    I'm learning fwbuilder and firewalls in general. I don't understand the differences between Policy, NAT and Routes. They all seem like they are just ways to tell the data where to go depending on what it is and where its coming from. What is the real difference? Is a properly configured firewall taking advantage of all three (Policy, NAT and Routes) or are they just three different ways to accomplish the same thing and you only need one of them?

  • Controller Error: Do I need to worry?

    - by Kryten
    I have a HP Pavillion dv5224ea Laptop with Windows 7 on it. Recently I discovered a Error in Event Viewer: The driver detected a controller error on \Device\Ide\IdePort1. (more details): - System - Provider [ Name] atapi - EventID 11 [ Qualifiers] 49156 Level 2 Task 0 Keywords 0x80000000000000 - TimeCreated [ SystemTime] 2010-03-07T12:43:07.090197600Z EventRecordID 30198 Channel System Computer Alistair-Win7 Security - EventData \Device\Ide\IdePort1 0000100001000000000000000B0004C002000000850100C00000000000000000000000000000000000000000000000000000000004100000 -------------------------------------------------------------------------------- Binary data: In Words 0000: 00100000 00000001 00000000 C004000B 0008: 00000002 C0000185 00000000 00000000 0010: 00000000 00000000 00000000 00000000 0018: 00000000 00001004 In Bytes 0000: 00 00 10 00 01 00 00 00 ........ 0008: 00 00 00 00 0B 00 04 C0 .......À 0010: 02 00 00 00 85 01 00 C0 ......À 0018: 00 00 00 00 00 00 00 00 ........ 0020: 00 00 00 00 00 00 00 00 ........ 0028: 00 00 00 00 00 00 00 00 ........ 0030: 00 00 00 00 04 10 00 00 ........ Event Viewer is recording A LOT of these errors (sometimes 13, one after the other!). Do I need to worry? What does this error mean? What device could "\Device\Ide\IdePort1" be? What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

  • ZFS - how to partition SSD for ZIL or L2ARC use?

    - by ewwhite
    I'm working with a Sun x4540 unit with two pools and newly-installed ZIL (OCZ Vertex 2 Pro) and L2ARC (Intel X25-M) devices. Since I need to keep these two pools in the near-term, I'd like to know how to partition these devices to serve both pools of data. I've tried format, parted and fdisk and can't quite seem to get the right combination to generate recognizable partitions for zpool add. The OS in this case is NexentaStor, but I will also need this for general OpenSolaris solutions.

  • Upstart multiple instances of service not working

    - by Dax
    I started playing with MongoDB on Lucid. Now I would like to run a DB and Config server on the same box. They both use the same binary to launch, but with different config files and running on different ports. All directories for log and lib is split so one goes to mongodb and the other to mongoconf. Each process can be started without any problems on their own. start mongodb stop mongodb start mongoconf stop mongoconf But if I try to start both, the second one would just start and exit. Using 'initctl log-priority debug' I got the following in the logs. Jan 6 12:44:12 mongo4 init: event_finished: Finished started event Jan 6 12:44:12 mongo4 init: job_process_handler: Ignored event 1 (1) for process 5690 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) main process (5690) terminated with status 1 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) goal changed from start to stop Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) state changed from running to stopping man 5 init shows that you can use instance names to differentiate the two. I tried using 'instance mongoconf' in the on upstart script and 'instance mongodb' in the other one, and it still fails. I can manually start the other process, so there is definitely no conflicts on port numbers or directories. Any ideas on what to try or how to get output on why it is 'terminated with status 1'? Thanx

  • Why should I choose either PCL or PS when both are supported

    - by Goyuix
    Obviously the answer depends to some degree on the various versions supported, but in general terms - is there any reason I should pick one over the other? PCL for art and PS for text? Does one typically require less RAM on the printer? Speed differences? For home use it doesn't matter and only professional print people will notice and care?

  • Explorer.exe keeps crashing during log in

    - by asif
    I have got a weird problem. My windows 7 has two user accounts (both are administrator). I can log in to one account and do all sort of work. But whenever I try to log in to other account, it shows a blank screen and a messagebox pops up with "windows explorer has stopped working". The options available are: Close the program Check online for a solution and close the program The problem signature is as follows: Problem Event Name: InPageError Error Status Code: c000009c Faulting Media Type: 00000003 OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 If I press alt+ctrl+del and then select start task manager, it also crashes. I can not run any program using runas command (from good profile) too. The task manager and runas programs all show same problem signature. I read the similar question and followed all the steps, but no luck. Later, I viewed the event log and found that, explorer.exe could not access a file. I checked the location but the file is there. The actual message is: Windows cannot access the file C:\Users\testuser\AppData\Local\Microsoft\Windows\Caches\{AFBF9F1A-8EE8-4C77-AF34-C647E37CA0D9}.1.ver0x0000000000000020.db for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Windows Explorer because of this error. The question is, how can I resolve this issue? Should I just delete the file or replace it with another one to stop explorer.exe from crashing? offtopic: What is the content of this file and why it is necessary?

  • NFS I/O monitoring

    - by Gordon
    I have a NFS mounted directory, and I'd like to monitor the I/O usage on it (MB/s reads and writes). What's the recommended way to do that ? This is the NFS client, I don't have access to the NFS server. I'm not interested in general I/O usage (otherwise I would use vmstat/iostat). It also has multiple NFS mounts, I'm interested in monitoring just one specific mount (or I might have used ethereal). Thanks!

  • Keyboard and monitor recommendations

    - by Dmn
    I'm about to get a 23" monitor to connect to my laptop for programming, and general multimedia besides. This is the monitor; what do you think? Also, would you recommend getting a keyboard to use instead of the laptop's one? It seems like it would be awkward otherwise. This is the keyboard I'm looking at because it seems to have the low laptop style keys. Would you recommend something different?

  • Replicate From OpenDJ to OpenLDAP?

    - by Joel K
    I am considering retiring some of our older OpenDJ LDAP servers and replacing with OpenLDAP. (seems to be more widely supported) I am wondering if it's possible to replicate directly from OpenDJ to OpenLDAP as an interim solution to remove the OpenDJ slaves and then flip the master over later. Is LDAP replication implementation specific or more general? I guess I'll have to just go give it a try, but I was looking for advice from someone who's been down this road.

  • Is a 2006 Mac Mini's processor upgradeable to a Core 2 Duo?

    - by chiurox
    I have a Mac Mini with Core Solo 1.5GHz, 512mb RAM, 60gb HDD, etc... I know, it's very old but since it's lying around here, I wanted to bump it up for general usage and some experimental iPhone development. Also, Snow Leopard can't be installed as it doesn't have enough RAM. I browsed around but I'm not sure if this Mac Mini's motherboard accepts a Core2Duo (at least a 2.0GHz). If anyone could inform me which generation of Core2Duo it still accepts, I'd be grateful.

  • How do you google bad reviews? [closed]

    - by zlog
    The first thing I like to do before I make technology choices or gadget purchases is find bad reviews of the things. That way, taking into consideration of the potential biases of the reviewer, I can evaluate the product/service for the worse it can be. How do people google (or search in general) for bad reviews? I usually just try googling "bad review [product/service]" or "[product/service] sucks", but I'm sure there are better ways.

  • Unable to logon using terminal server connection

    - by satch
    I have several W2K3 SP2 servers, admin TS enabled. I discovered this morning, I was unable to logon into some of them. I've a couple of Citrix servers in different farms, a SAP (IA64) app server and a cvs server. All of them show same sympthoms; remote connections are refused. I've been able to logon locally, and terminal server service is up, there are no users (so connections are not depleted). There are no errors in log in most servers. One of the Citrix ones, reported following errors: Event ID 50 Source TermDD Type Error Description The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client. and Event ID 1006 Source TermService Type Error Description The terminal server received large number of incomplete connections. The system may be under attack. Anyway, I suppose these errors appear because server isn't working, and Citrix users try to logon massively. (I nmap'ed server and port seems up). I've solved this problem rebooting before, but with so many servers affected it seems like a crappy workaround. Any idea about troubleshooting it properly? Thanks in advance

  • Passing parameters to a shell script running as a cronjob

    - by Takashi
    I am new to bash scripting (not programming in general). I am writing a bash script that will run a Python script I have written. I want to be able to do the following: Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo' switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).

  • putty external text editor?

    - by matthewsteiner
    I'm new to ssh and linux in general. I've got putty set up and I can connect to my server and list files and everything. I'm wondering how I can edit a file using notepad++ (or another editor). Is there a way to have it automatically download and upload through ssh? How else do you edit a file? Thanks

  • Backing up MySQL DB wtih mixture of innodb and myisam tables

    - by madphp
    I have a large database (almost 1GB) and it has a mixture of innodb and myisam tables. Does anyone have any general tips when backing it up or more specifically the commands i should send to mysqldump. I see that i should lock myisam tables, and that single transactions for innodb, but what if i have both. Also, what is actually happening when i lock an entire (very big) table on a production database.

  • Problems configuring logstash for email output

    I'm trying to configure logstash to send email alerts and log output in elasticsearch / kibana.

  • How to install SSL on current site?

    - by vpoola88
    So I've looked at a ton of guides, but non of them seem to get our site to work. This is what I was probably following the closest:https://www.digitalocean.com/community/articles/how-to-create-a-ssl-certificate-on-apache-for-ubuntu-12-04 I also wanted to know why there is a default-ssl in apache2/sites-available ? Is this where I would have to put my configuration? This is my first exposure to SSL and site deployment in general. Thanks guys.

  • After connecting wlan0 to bridge interface (and then removing it), can't connect to AP

    - by gmonk
    I'm on a laptop running Debian Jessie with kernel 3.13-1-amd64; lspci shows that my wireless NIC + driver is 04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 3160 Kernel driver in use: iwlwifi This has been working without any problems, until I tried creating a bridge for lxc containers to use. I did the same thing as this person here: How-to set up a network bridge on a laptop for LXC use? -- and ended up having the same problem as this poster did, so I decided to "undo" my actions.

I'm not sure what I did wrong, or what step I've skipped in trying to get wlan0 back as a non-bridged device -- I removed it from the bridge and then deleted the bridge itself. Any ideas?

  • EFS Remote Encryption

    - by Apoulet
    We have been trying to setup EFS across our domain. Unfortunately Reading/Writing file over network share does not work, we get an "Access Denied" error. Another worrying fact is that I managed to get it working for 1 machine but no other would work. The machines are all Windows 2008R2, running as VM under ESXi host. According to: http://technet.microsoft.com/en-us/library/bb457116.aspx#EHAA We setup the involved machine to be trusted for delegation The user are not restricted and can be trusted for delegation. The users have logged-in on both side and can read/write encrypted files without issues locally. I enabled Kerberos logging in the registry and this is the relevant logs that I get on the machine that has the encrypted files. In order for all certificate that the user possess (Only Key Name changes): Event ID 5058: Audit Success, "Other System Events" Key file operation.

The problem is that the users I using at the moment can not change their password.

  • Disabling LDAP Signing on Windows PDC in Local Policy

    - by Golmaal
    I just tripped over my own feet it seems. Playing around on a Windows 2008 R2 server (set up as domain controller), I was intrigued by certain warning event (event id 2886) which says: "To enhance the security of directory servers, you can configure both Active Directory Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS) to require signed Lightweight Directory Access Protocol (LDAP) binds." So I thoughtlessly did some Googling and set the relevant policies which enforce LDAP signing. Now I don't remember but I may have done that using Local Policy. Now I have setup a pfsense box which must authenticate AD users via LDAP. While the firewall can communicate over secure channel, it is difficult to manage the same for other packages such as Squid and SquidGuard. So now I have to disable i.e. undo those policy changes. The problem is that they are greyed out! The policies in question are LDAP server signing and LDAP client signing. I don't remember what I did but when I access these policies from Local Policy editor on the server, they are set to "Require Signing" and are greyed out. The same policies can still be set via Default Domain Controller option in Group Policy editor. So how can I reset these greyed out policies? Thanks

  • SQL Clustering on Hyper V - is a cluster within a cluster a benefit.

    - by Chris W
    This is a re-hash of a question I asked a while back - after a consultant has come in firing ideas in to other teams in the department the whole issue has been raised again hence I'm looking for more detailed answers. We're intending to set-up a multi-instance SQL Cluster across a number of physical blades which will run a variety of different systems across each SQL instance. In general use there will be one virtual SQL instance running on each VM host. Again, in general operation each VM host will run on a dedicated underlying blade. The set-up should give us lots of flexibility for maintenance of any individual VM or underlying blade with all the SQL instances able to fail over as required. My original plan had been to do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Within the VMs - create a failover cluster and then install SQL Server clustering. The consultant has suggested that we instead do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Create a cluster on the HOST machines which will host all the VMs. Within the VMs - create a failover cluster and then install SQL Server clustering. The big difference is the addition of step 4 whereby we cluster all of the guest VMs as well. The argument is that it improves maintenance further since we have no ties at all between the SQL cluster and physical hardware. We can in theory live migrate the guest VMs around the hosts without affecting the SQL cluster at all so we for routine maintenance physical blades we move the SQL cluster around without interruption and without needing to failover. It sounds like a nice idea but I've not come across anything on the internet where people say they've done this and it works OK. Can I actually do the live migrations of the guests without the SQL Cluster hosted within them getting upset? Does anyone have any experience of this set up, good or bad? Are there some pros and cons that I've not considered? I appreciate that mirroring is also a valuable option to consider - in this case we're favouring clustering since it will do the whole of each instance and we have a good number of databases. Some DBs are for lumbering 3rd party systems that may not even work kindly with mirroring (and my understanding of clustering is that fail overs are completely transparent to the clients). Thanks.

  • putty external text editor?

    - by matthewsteiner
    I'm new to ssh and linux in general. I've got putty set up and I can connect to my server and list files and everything. I'm wondering how I can edit a file using notepad++ (or another editor). Is there a way to have it automatically download and upload through ssh? How else do you edit a file? Thanks

  • EventID 1058 Code 5, Sysvol is subdir of Sysvol - how to fix?

    - by nulliusinverba
    I have been trying to resolve this error, like many others: The processing of Group Policy failed. Windows attempted to read the file \domain.local\SysVol\domain.local\Policies{3EF90CE1-6908-44EC-A750-F0BA70548600}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: a) Name Resolution/Network Connectivity to the current domain controller. b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). c) The Distributed File System (DFS) client has been disabled. Error code: 5 = Access Denied. The incredibly helpful post is this one (http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/A_1073-Diagnosing-and-repairing-Events-1030-and-1058.html). Quoting from this post: HERE IS A LIST OF POTENTIAL PROBLEMS THAT CAN LEAD TO 1030 AND 1058 EVENT ERRORS: --Sometimes the permissions of the file folders that contain Group policies (the Sysvol folder) can be corrupted. --Sometimes you have problems with NetBIOS: --Sometimes the GPO itself is corrupt, or you have a partial set of data for that GPO. --Sometimes you may have problems with File Replication Services, which almost always indicates a problem with DNS --Sysvol may be a subfolder of itself: Sysvol/Sysvol I have the problem listed where sysvol is a subfolder of sysvol. The directory structure is: -sysvol -domain -staging -staging areas -sysvol (shared as "\\server\sysvol") -domain.local -ClientAgent -Policies -scripts Interestingly, the second sysvol folder is the one that is shared as "\server\sysvol". This makes me confident this is the issue with the permissions and error code 5. Also interestingly, my server 2008 R2 servers can see it fine - my server 2008 servers cannot, and get the error. This is consistent across all my servers. This latter fact makes me uncertain what I need to do to fix this up. Do I, e.g., simply move the shared sysvol folder up a level to replace the non-shared one? Any help greatly appreciated. Cheers, Tim.
