  • LDAP authentication issue with Kerio Connect

    - by djk
    We have Kerio Connect (mail server) running on a Windows Server 2003 server on a domain. In the webmail client, users are able to change their domain password. This functionality used to work fine until a user tried to change their password a few days ago, when every password they'd try would result in the webmail client claiming their password was "invalid". I spoke to Kerio about this and they claim that this error is returned by the domain controller, which supports my initial investigations. The error that the DC is logging when an attempt is made to change the password is this: "80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 52e, vece" The "data 52e" part indicates that this is an "invalid credentials" error. I don't see how this can be as I've tried (in the Kerio Connect configuration) various accounts that have privileges to modify accounts, including my own as I am a domain admin. I have ran 'dcdiag' (all tests) on the DC and it came back passing every single one of them. I've searched high and low for an answer to this and came up empty. Does anyone have any idea why this may have suddenly started happening? Thanks! Edit: I should mention that the passwords we are changing to do comply with the complexity policy.

  • Windows 2003 Domain Controller Very Upset about NIC Teaming

    - by Kyle Brandt
    I set up BACS (Broadcom Teaming) to team two NIC on a Windows 2003 Active Directory Domain Controller. Networking still works okay, I can ping the gateway etc, but both DNS and Active Directory fail to start with various 40xx errors. The team that I created is Smart load Balancing with Failover, with one backup and only one in smart load balancing (So really it is just failover). I have the team the same IP address that the single active NIC had before. Anyone seen this before, or have any ideas what the problem might be? Event Type: Error Event Source: DNS Event Category: None Event ID: 4015 Date: 3/7/2010 Time: 10:33:03 AM User: N/A Computer: ADC Description: The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error. Event Type: Error Event Source: DNS Event Category: None Event ID: 4004 Date: 3/7/2010 Time: 10:33:03 AM User: N/A Computer: ADC Description: The DNS server was unable to complete directory service enumeration of zone .. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empty) is "". The event data contains the error. Event Type: Error Event Source: NTDS Replication Event Category: DS RPC Client Event ID: 2087 Date: 3/7/2010 Time: 10:40:28 AM User: NT AUTHORITY\ANONYMOUS LOGON Computer: ADC Description: Active Directory could not resolve the following DNS host name of the source domain controller to an IP address. This error prevents additions, deletions and changes in Active Directory from replicating between one or more domain controllers in the forest. Security groups, group policy, users and computers and their passwords will be inconsistent between domain controllers until this error is resolved, potentially affecting logon authentication and access to network resources.

  • RAID-1 and regular drive removal (using RAID-1 as a backup measure)

    - by Vi
    Is using mdadm's RAID-1 of 2 partitions (one on laptop's internal HDD, one on external HDD) a good idea. I want the system to work as RAID-1 if both drives are present, work as regular volume (degradad RAID-1) if external HDD is unplugged and quickly resync when I plug external HDD again. Questions: Is it a good idea? Will write-intent bitmap be enough for this task or I need something else? Should I consider doing it at filesystem level (3b. if yes, how?). Basic requirements are: Quick resync when I re-add the external drive (provided I hasn't changed that partition). More or less consistent data on the removed drive if I remove it not during write/resync operation. If I remove the drive during resync I expect the data to be somewhat inconsistent, but expect quick resync completion when I re-add it again. E.g. I want the the remaining drive to track what is changed (there can be a lot of changes) and that sync back only those parts that need it.

  • iSCSI errors continue after removing inaccessible target portal

    - by Ansgar Wiechers
    By mistake I entered an iSCSI target portal address in the iSCSI Initiator on one of our virtual servers that does not have an address in the network range used for iSCSI. This caused the following errors/warnings to appear in the eventlog: Log Name: System Source: MSiSCSI Event ID: 113 Level: Warning Description: iSCSI discovery via SendTargets failed with error code 0xefff0003 to target portal *192.168.23.42 0003260 Root\ISCSIPRT\0000_0 . Log Name: System Source: iScsiPrt Event ID: 1 Level: Error Description: Initiator failed to connect to the target. Target IP address and TCP Port number are given in dump data. Log Name: System Source: iScsiPrt Event ID: 70 Level: Error Description: Error occurred when processing iSCSI logon request. The request was not retried. Error status is given in the dump data. So far that's expected beahvior, so I removed the portal from the iSCSI Initiator as described in MSKB 976072. However, the errors/warnings keep appearing every hour, even though neither iSCSI Initiator GUI nor iscscli show any portals: C:\>iscsicli ListTargetPortals Microsoft iSCSI Initiator Version 6.1 Build 7601 The operation completed successfully. The problem persists after rebooting the server. Uninstalling the Microsoft iSCSI Initiator device via devmgmt.msc as well as changing the Initiator parameters like this: [HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318}] "MaxPendingRequests"=dword:00000001 "MaxConnectionRetries"=dword:00000001 "MaxRequestHoldTime"=dword:00000005 didn't help either. Each change was followed by a reboot. Disabling the device does prevent the errors/warnings from re-appearing, of course, but I'd rather not have to resort to this. How can I prevent those errors and warnings from appearing (short of disabling the initiator device or re-installing the server)? What am I missing? Environment: The virtual machine runs on a Hyper-V cluster managed by SCVMM 2012. Hosts and guests run Windows Server 2008 R2 SP1. The physical machines are Dell PowerEdge M710HD blades.

  • Can I change the file system on the OS partition on Server 2008 R2?

    - by KCotreau
    I have a client using R1Soft Continuous Data Protection backup, and two of the Server 2008 R2 boxes were erroring out with these errors: Unable to obtain NTFS volume data for device '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}': Incorrect function. Unable to discover information for filesytem volume '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}'; Unable to obtain NTFS volume So I backed up all the registry entries with this, {f612849e-7125-11e0-8772-806e6f6e6963}, in it, and deleted them based on some VERY sparse info from R1Soft. I then decided to restore them before I rebooted, and do a system state backup first using MS backup, and even it errored out saying that there were FAT32 partitions. This was a major clue as the only two computers with problems had these FAT32 partitions. I figured if MS backup can't backup something, any other program is likely to have problems. Also, now that I realized the servers had FAT32 partitions on them, the error referencing NTFS takes on more weight. The partitions on both servers have the label "OS", but on one of the computers, it is given a letter, but on the other not. So I am thinking if I just convert the file systems from FAT32 to NTFS, it may solve the backup problem. So the question is this: Can I just convert those partitions, and does anyone have any concrete knowledge of any major downsides, like the servers not coming back up (of course, I would do one at a time)? My thinking is that the answer is probably at least 95% no, but they are production servers, so I wanted to get some second opinions.

  • Mounting a TrueCrypt volume over FTP

    - by Maxim Zaslavsky
    Is it possible to mount a TrueCrypt volume file over FTP? Here's how TrueCrypt works with a local file: User inputs path to volume file, enters password TrueCrypt verifies that the password is correct (probably by decrypting the very first part of the volume file?) TrueCrypt reads the directory listing from the volume file and mounts the volume. However, in this step, TrueCrypt does NOT process the whole volume file. The user browses the directory listing and opens a file. TrueCrypt reads only the part of the volume file that contains the file the user wants, and then decrypts it. Once again, TrueCrypt doesn't process the whole volume file - it only reads part of it. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file. I'm pretty sure it should be possible to mount a volume over FTP, without undermining security and without having to transfer the whole volume file just to read one small part of the volume. Here's how I imagine it: User inputs FTP path to volume file, enters FTP login information, enters password to volume TrueCrypt downloads the very first part of the volume file and verifies that the password is correct TrueCrypt downloads the part of the volume file that contains the directory listing - the data is sent encrypted over FTP and is decrypted locally. The user browses the directory listing and opens a file. TrueCrypt downloads only the part of the volume file that contains the file the user wants, and then decrypts it locally. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file over FTP, transferring encrypted data only. Is such a feature available?

  • ssh tunnel - bind: Cannot assign requested address

    - by JosephK
    Trying to create a socks (-D) ssh tunnel - Linux box to Linux box (both centos): sshd running on remote side ok. From local machine we do / see this: ssh -D 1080 [email protected]. [email protected]'s password: bind: Cannot assign requested address (where 8.8.8.8 is really my server's IP and 'user' is my real username) I am logged into the remote side in this terminal-window. I can verify that the local port was unused prior to this command, and then used by an ssh process, after the command, via: netstat -lnp | grep 1080 So, unlike most googled-responses with this error, the problem would not seem to be the loopback interface assignment. If I try to use this tunnel with a mail client, the local-side permits the attempt (no 'proxy-failed' error), but no data / reply is returned. On the remote side, I do have "PermitTunnel yes" in my sshd_config (though 'yes' should be the default, anyway). Ideas or Clues? Here is the relevant debug-output OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * .... debug1: Authentication succeeded (password). debug1: Local connections to LOCALHOST:1080 forwarded to remote address socks:0 debug1: Local forwarding listening on 127.0.0.1 port 1080. debug1: channel 0: new [port listener] debug1: Local forwarding listening on ::1 port 1080. bind: Cannot assign requested address debug1: channel 1: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: Sending env LANG = en_US.utf8 Other clue: If I run a Virtual Box on the client running Windows, open a tunnel with putty in that box, that tunnel, to the same remote server, works.

  • Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

    - by erinloy
    I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

  • Screen scraping software that will traverse pages

    - by nilbus
    We're creating a mashup site that pulls information from many sources all over the web. Many of these sites don't provide RSS feeds or APIs to access the information they provide. This leaves us with screen scraping as our method for collecting the data. There are many scripting tools out there written in different scripting languages for screen scraping that require you to write scraping scripts in the language the scraper was written in. Scrapy, scrAPI, and scrubyt are a few written in Ruby and Python. There are other web-based tools I've seen like Dapper that create XML or RSS feeds based on a webpage. It has a beautiful web-based interface that requires no scripting skills to use. This would be a great tool, if it were able to traverse multiple pages to gather data from hundreds pages of results. We need something that will scrape information from paginated web sites, much like scrubyt, but with a user interface that a non-programmer could use. We'll script up our own solution if we need to, probably using scrubyt, but if there's a better solution out there, we want to use it. Does anything like this exist?

  • PHP upgrade to 5.3 from 5.2, sessions no longer get stored

    - by Damo
    background link: http://stackoverflow.com/questions/7014945/php-upgrade-5-2-to-5-3-session-issue I have upgraded PHP on my 2008 std server from PHP 5.2 to PHP 5.3. Following the upgrade, sessions no longer work correctly. I have copied over the settings from my PHP.ini files which are applicable and configure new settings in line with the server or PHP's recommendations. PHP executes fine correctly, however session data does not get saved. I have session data stored in c:\temp. For each session created, I can see the session file in this folder. However no information gets written into the session file. Permissions wise, IUSR and EVERYONE has write access to this folder. If I downgrade to PHP 5.2, sessions are saved correctly and the site functions correctly.

  • SuperMicro BMC on OpenSuSE Linux --cannot access from LAN

    - by Kendall
    Hi, I have an (old) SMC-001 IPMI device on an (old) X6DVL-EG2 motherboard. My problem is that I cannot access the BMC from LAN. I'm also getting some interesting output from ipmitool. First, the setup. I enable Console Redirection in the BIOS, turn BIOS Redirection after POSt to "disabled". I then modprobe'ed for ipmi_msghandler, ipmi_devintf and ipmi_si. I then found ipmi0 under /dev. So far so good. Since I want console redirection over serial, I modified /boot/grub/menu.lst: http://pastebin.com/YYJmhusQ I then modified "/etc/inittab" as follows: S1:12345:respawn:/sbin/agetty -L 19200 ttyS1 ansi Networking I set as following, using "ipmitool" ipaddr: 192.168.3.164 netmask: 255.255.255.0 defgw: 192.168.3.1 The above are correct for my environment. To test it I do: ipmitool -I open chassis power off which responds by powering off the machine. When I to access from another computer on the network, however, I get an error message: host# ipmitool -I lanplus -H 192.168.10.164 -U Admin -a chassis power status Error: Unable to establish LAN session Unable to get Chassis Power Status "Admin" seems to be a valid user name: host# ipmitool -I open user list 1 2 Admin true false true USER The interesting output from ipmitool I initially mentioned: host # ipmitool -I open lan set 1 access on Set Channel Access for channel 1 failed: Request data field length limit exceeded Also, newload4:/home/gjones # ipmitool channel info 1 Channel 0x1 info: Channel Medium Type : 802.3 LAN Channel Protocol Type : IPMB-1.0 Session Support : session-less Active Session Count : 0 Protocol Vendor ID : 7154 Get Channel Access (volatile) failed: Request data field length limit exceeded The output of "ipmitool -I open lan print 1" is here: http://pastebin.com/UZyL6yyE Any help/suggestions is greatly appreciated; I've been working with this thing for a few hours now with no success.

  • Non-functioning AutoFilter on Locked Cells in Office 2008 - works in Office 2007

    - by Sarcas
    I'm looking into a problem for someone, who works in a mixed OS environment. She has created an Excel spreadsheet in Office 2007 to act as a directory, with AutoFilter turned on for names, email addresses, departments etc. To make sure no one accidentally edits email addresses (for example), she has protected the work sheet. Accessing this worksheet on a PC running Excel 2007, everything runs as you'd expect. You can filter the sheet by any of the auto-filtered columns, and because the sheet is protected, the data integrity is guaranteed. However, if you access the sheet on a Mac running Excel 2008, you can't filter the columns. What's strange here is that the AutoFilter dropdown arrows do appear in each of the column headers as you would expect. It's just that nothing happens if you click on them. If you select one of the column header cells (say, 'First Name') and check the menu: Data-Filter, you can see that AutoFilter is ticked. As another datapoint, you also seem to be able to apply an Advanced filter to these rows on the protected sheets. Does anyone know why this might be? It seems to be a compatibility issue between Excel 2007/2008 (I know the codebase isn't the same), but I can't find any references to it in documentation or forums anywhere, and it would be good to know if there's a way around this. Thanks!

  • VMWare ESX, storage over 2TB

    - by Phliplip
    Hi, First of, i'm a webdeveloper and my server experience lies in setting up FreeBSD servers for webserver. I'm working on a project for at photographer, and i'm hired to develop a new online photo ordering system - where user of course can view their photos :) They have a massive need of storage, thus we have bought a HP G6 and 8x1TB SATA HDD. Our plan is to install VMWare ESX 4.0, running multiple virtual machines; FreeBSD 8 for webserver and some windows servers. Allready done that. Then mount one big storage to the BSD, and share it through Samba to the WinServers. The raid is set up with an array of 2x 1TB to handle the VMs. And the rest is setup as 3 2x1TB to handle the photo-data. Thus 2.73TB for photo-data (the raids are 1+0). Now if we add a datastore in the ESX and add the 3 LUNs we can get a datastore of 2.74TB. But i don't se how i can add this datastore direct to the VM. Only the BSD VM needs access to this. Only way is to create a VirtualDisk, with a max of 2TB (8MB blocksize). This is because the datastore where we save the virtualdisk has a maximum filesize of 2TB. Then add it as a harddisk to the BSD VM. In the 'Add Harddisk' pane for the VM, i see an option for Raw Disk Management. I think this is to access the datastore or the raid directly. Only problem is that its greyed out! Can i access the datastorage directly from the BSD? Without creating and adding virtualdisk.

  • mysql master-master setup as a way to simply master-slave promotion

    - by Chris Go
    I'm trying to see if the following plan is viable. Goal here is to be able to do HA (uptime) and not necessarily for load -- writes are fine on one MySQL 5.5 server (with innodb) but not really possible when the database is down. Currently, I have a master-slave replication setup which works fine except it doesn't have automatic promotion (obviously). what I am planning on doing is setup master-master replication to possibly do this "automatic promotion" using Amazon Route 53 DNS Failover (Health checks). What I am trying to avoid is to NOT have to do the auto-increment trick because the "business folks" got used to the auto-incrementing PK as consecutive numbers (yeah, I know this is bad but data is from 2004). So, setup the master-master replication WITHOUT the auto-increment collision prevention bit. The primary master is db1.domain.com and secondary master is db2.domain.com In Amazon Route 53, setup DNS Failover record for db.domain.com - primary failover is db1.domain.com - with a TCP healthcheck on IP address port 3306 - secondary failover is db2.domain.com - with a TCP healthcheck on IP address port 3306 Most of the time (99%), unless tcp://db1.domain.com:3306 is dead, db1.domain.com will be served up on DNS hits to db.domain.com. In fact, hopefully this is 100%. The possible downsides of this is the loss of a primary key (collision) and I think I am OK with losing one order. We are a low data volume B2B business and can just call our client up if this occurs (like an order disappearing). Does this sound like a good plan? Then I will also run another slave replication on db1.domain.com as "master" to a slave-db1.domain.com -- not sure why, maybe for heavy SELECTs?

  • How to repair multiple KDC an Netlogon errors

    - by Keith Sirmons
    Howdy, I have several erros in the system event log of my single Windows 2003 SP2 domain controller. Multiple member computers on the domain are listed in these errors. I am seeing two similar errors for each computer one second apart in the event log. Event ID 7 Source KDC The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was [email protected] and lookup type 0x8. followed by Event ID 7 Source KDC The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was MEMBERNAME$ and lookup type 0x8. The Lookup Types are also different, I have 0x8, 0x28, 0x0, 0x20. I am also receiving other authentication errors in the same time frame as all of the KDC errors Event ID 5722 Source NETLOGON The session setup from the computer MEMBERNAME failed to authenticate. The name(s) of the account(s) referenced in the security database is MEMBERNAME$. The following error occurred: Access is denied. I have run dcdiag /v to see if there was something wrong with Active Directory, but all tests passed. I also ran netdiag /v and it appers all of those tests ran. Any ideas on where to start for this issue? Thank you, Keith

  • Can compressing Program Files save space *and* give a significant boost to SSD performance?

    - by Christopher Galpin
    Considering solid-state disk space is still an expensive resource, compressing large folders has appeal. Thanks to VirtualStore, could Program Files be a case where it might even improve performance? Discovery In particular I have been reading: SSD and NTFS Compression Speed Increase? Does NTFS compression slow SSD/flash performance? Will somebody benchmark whole disk compression (HD,SSD) please? (may have to scroll up) The first link is particularly dreamy, but maybe head a little too far in the clouds. The third link has this sexy semi-log graph (logarithmic scale!). Quote (with notes): Using highly compressable data (IOmeter), you get at most a 30x performance increase [for reads], and at least a 49x performance DECREASE [for writes]. Assuming I interpreted and clarified that sentence correctly, this single user's benchmark has me incredibly interested. Although write performance tanks wretchedly, read performance still soars. It gave me an idea. Idea: VirtualStore It so happens that thanks to sanity saving security features introduced in Windows Vista, write access to certain folders such as Program Files is virtualized for non-administrator processes. Which means, in normal (non-elevated) usage, a program or game's attempt to write data to its install location in Program Files (which is perhaps a poor location) is redirected to %UserProfile%\AppData\Local\VirtualStore, somewhere entirely different. Thus, to my understanding, writes to Program Files should primarily only occur when installing an application. This makes compressing it not only a huge source of space gain, but also a potential candidate for performance gain. Testing The beginning of this post has me a bit timid, it suggests benchmarking NTFS compression on a whole drive is difficult because turning it off "doesn't decompress the objects". However it seems to me the compact command is perfectly capable of doing so for both drives and individual folders. Could it be only marking them for decompression the next time the OS reads from them? I need to find the answer before I begin my own testing.

  • How to remove a plain text protecting single quote from all the selected cells in LibreOffice Calc?

    - by Ivan
    I've imported a CSV file having the first column to be date-time values in ISO 8601 format like 2012-01-01T00:00:00.000Z for the first moment of the year 2012. Then, willing to make LibreOffice to recognize the format (as I was looking forward to plot a diagram), I've selected the column, chosen Format Cells... and entered the custom time format as YYYY-MM-DDTHH:MM:SS.000Z And this seems to work if... I edit a cell to remove a hidden single-quote from its beginning (which serves to protect a cell content from being interpreted) as all the newly formatted cells now store values like '2012-01-01T00:00:00.000Z (note the single quote - it is only visible when you edit a particular cell). And I am to do so for all the cells in the column. How can I automate this? UPDATE: I've already found a solution for the particular case of mine: it helps to set a column format to "time" in the CSV import dialogue. But I am still curious how could this be done in case I wouldn't have the original .csv data file to import but only the .ods file with the data already imported without the format specified at the import time.

  • Mac OS X - User home directories shared via NFS

    - by Hugh
    I've run into some problems with how I've got user home directories set up on our system here. Our server is an XServe, using Open Directory to manage the user accounts. The majority of our workstations are OS X, but there are a few running Linux (Centos 5.3), and, as time goes on, we expect the proportion of Linux workstations to increase (at some point, we expect to move the server side over to Linux too, but for now we're running with what we've already got) To ensure that the Linux and OS X workstations both see user's home directories in the same place, I shared the home directories using NFS. On the server end, the home directories are stored in: /Volumes/data/company_users This is mounted on the workstations to: /mount/company_users This work fine on the Linux workstations, but there is some weirdness under OS X. For the user who is logged in through the GUI, it all works just fine. However, if a user tries to SSH into a machine that they are not the primary user on, they often have no access to their own home directory. It looks as though OS X is trying to do something else to the user home directories mount point when you log in through the GUI.... For example, on this machine (nv001), I (hugh) am logged into the GUI. Last login: Mon Mar 8 18:17:52 on ttys011 [nv001:~] hugh% ls -al /mount/company_users total 40 drwxrwxrwx 26 hugh wheel 840 27 Jan 19:09 . drwxr-xr-x 6 admin admin 204 19 Dec 18:36 .. drwx------+ 128 hugh staff 4308 27 Feb 23:36 hugh drwx------+ 26 matt staff 840 4 Dec 14:14 matt [nv001:~] hugh% So Matt's home directory is accessible to him. However, if I try to switch to him: [nv001:~] hugh% su - matt Password: su: no directory [nv001:~] hugh% Or: [nv001:~] hugh% su matt Password: tcsh: Permission denied tcsh: Trying to start from "/mount/company_users/matt" tcsh: Trying to start from "/" [nv001:/] matt% Does anyone have any idea why it might be doing this? It's causing me all sorts of problems at the moment... The only machine that I can successfully switch users at the moment is the server that the user directories are stored on, where /mount/company_users is actually just a symlink to /Volumes/data/company_users

  • How to update-grub on a system running overlayroot?

    - by mikepurvis
    We ship boxes configured with overlayroot, using the following overlayroot.conf: overlayroot=device:dev=/dev/sda6,timeout=20,recurse=0 Which produces the following mount configuration: $ mount overlayroot on / type overlayfs (rw,errors=remount-ro) /dev/sda5 on /media/root-ro type ext3 (ro,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda6 on /media/root-rw type ext3 (rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda1 on /boot type ext3 (rw) As you can see, three key physical partitions: sda1 is /boot, sda5 is a read-only "factory" root, and sda6 is a "user" root which can be wiped at any point to restore the machine to its original factory state. Now, the problem arises when update-grub is run for any reason: $ sudo update-grub [sudo] password for administrator: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). Understandable, since / is an overlayfs. The contents of /usr/sbin/update-grub are: #!/bin/sh set -e exec grub-mkconfig -o /boot/grub/grub.cfg "$@" With /usr/sbin/grub-mkconfig being the business part of things. But the actual problem is in /usr/sbin/grub-probe, called by grub-mkconfig, and grub-probe is a binary. So my question is, is there a parameter or whatever which can make grub-probe do the right thing in the face of / being an overlayfs? And secondly, is there a way to hack/patch that in so that the update-grub script just does the right thing? Thanks.

  • How to find out where or if MYSQL5 logs are stored on a machine WHM/Cpanel

    - by moi
    I have a WHM/Cpanel re-seller hosting account on a virtual private server (Linux). I have root access to the machine via SSH I am trying to locate a file that contains information that will help me to determine which users have accessed what db and from which hosts. I would imagine this kind of data is stored in a log file somewhere. The MySQL page says: The general query log - Established client connections and statements received from clients See: http://dev.mysql.com/doc/refman/5.0/en/server-logs.html It also says: By default, all log files are created in the mysqld data directory. So, I am am NOT asking where are the general query log logs stored, (cos I expect I will get answers saying "it depends") Please help me work out: "How can go about finding out where MySQL general query log logs are stored on a linux machine" Couple of things i've already tried: I looked at /etc/my.cnf it was a tiny file that only contained the following info: [mysqld] skip-bdb skip-innodb set-variable = max_connections=500 safe-show-database ~ ~ I have looked in: /var/lib/mysql/ But I could not see any log-like file names in that directory. Any clues on this would be most welcome.
