  • Amazon AWS VPN how to open a port?

    - by Victor Piousbox
    I have a VPN with public and private subnets; I am considering only public subnet for now. The node 10.0.0.23, I can ssh into it. Let's say I want to connect to MySQL on the node using its private address: ubuntu@ip-10-0-0-23:/$ mysql -u root -h 10.0.0.23 ERROR 2003 (HY000): Can't connect to MySQL server on '10.0.0.23' (111) ubuntu@ip-10-0-0-23:/$ mysql -u root -h localhost Welcome to the MySQL monitor. Commands end with ; or \g. --- 8< --- snip --- 8< --- mysql> The port 3306 is not reachable if I use the private IP? My security group allows port 3306 inbound from 0.0.0.0/0 AND from 10.0.0.0/24. Outbound, allowed all. The generic setup done by Amazon through their wizard does not work... I add ACL that allows everything for everybody, still does not work. What am I missing?

  • Why Is Volume Shadow Copy Services stopping?

    - by David Mackintosh
    I am running Windows 7 Professional, 64-bit. I am running a backup-over-the-internet software client which depends on the Volume Shadow Copy Services running. Since I installed Service Pack 1 (or rather, didn't object when Windows Update forced Service Pack 1 on me) the backup service is failing to back everything up because VSC isn't running. Most of the time it fails to back up such noise as the Security Essentials database or the Messenger Live contact list -- stuff I really don't care about -- but I don't want to fall into the trap of accepting an Error-state backup as "normal". At the recommendation of the backup software, I have set the VSC service startup mode to be Automatic. When I look in the Event Log, System channel I can see at boot time: The Volume Shadow Copy service entered the running state. ...and then two or three minutes later: The Volume Shadow Copy service entered the stopped state. How do I figure out why VSC is stopping? At the suggestion of the backup vendor, I have already followed the suggestions from http://support.microsoft.com/default.aspx/kb/940184 net stop SENS net stop EventSystem net start EventSystem net start SENS net stop COMSysApp net stop SwPrv net stop VSS cd /d C:\Windows\system32 regsvr32 ole32.dll /s regsvr32 oleaut32.dll /s regsvr32 vss_ps.dll /s vssvc /register /s regsvr32 /i swprv.dll /s regsvr32 /i eventcls.dll /s regsvr32 es.dll /s regsvr32 stdprov.dll /s regsvr32 vssui.dll /s regsvr32 msxml.dll /s regsvr32 msxml3.dll /s regsvr32 msxml4.dll /s net start SwPrv net start VSS net start ProtectedStorage ...and per http://support.microsoft.com/kb/940184 I have deleted the key tree HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions I have also run chkdsk /F and chkdsk /R on both permanent hard disks. (I had a similar problem with another computer (same OS, same failure, same start point after SP1 install) but the problem went away when I forced Volume Shadow Copy Services to Automatic startup rather than Manual. I did not have to resort to following the Microsoft KB instructions.)

  • Deleting certain files sits at "preparing to recycle" on Windows 7?

    - by Rachel
    We recently setup one of our users with a brand new Windows 7 computer, however she is unable to delete certain files. With some testing, I found I cannot move, rename, or view properties of these files either. When trying to delete the file, it just sits at the "Preparing to recycle" popup, however the "from" section says "Discovering items..." Clicking "More Details" on the popup shows me that it can't find the file name or where it's recycling from: Other notes... All the affected files are .pdf files that get created via a scanner. Other pdf files are fine. Opening the files works fine. I can open the file, Save As a new file, and delete the new one just fine Trying to delete the file via command prompt just sits there Rebooting the computer will let me manipulate the files like normal, however this user is responsible for scanning hundreds of documents a day and I'd rather not have to tell her to reboot her computer to delete files. The user is part of the administrator group on the computer The Owner of the affected files is the user attrib of files is just A

  • Anti Virus Service does not run - Windows XP SP3 32bit Home

    - by Stefan Fassel
    I have a somewhat strange problem here. I am trying to run Anti Virus Software on my Windows XP Home 32bit System. After a serious crash I had to fall back to an outdated copy of my initial installation and had Windows install 5 years of updates. So far so good. After Intalling a new Anti Virus Software (Bitdefender 2012) everything seemed to be fine, initial scanning went fine and configuration was working. But after restarting the System the Virus Scanner was unable to start up again. Even the Configuration console of the AV Software did not start. I tried scanning the System for malware, but nothing was found. Then I tried a different AV Software (MS Security Essentials), but in the end it did fail to start too. I have tried to start the Service manually, but I seem to be missing the privilege to do so. I am logged in as a Non-"Administrator" User with Admin privileges (Not much choices there on a XP Home System). I cannot switch to Administrator account outside the protected mode. When running Windows in protected mode I am unable to start the AV Software because it does not run in protected mode. I am a bit at loss now...

  • Outlook certificate error and separate send/receive error

    - by Richard
    I run a laptop with Vista 32bit and MS Office 2010. Outlook has two profiles, both configured as POP3/SMTP and neither go through an exchange server. Recently, one of the mail servers (hosted with easily) was getting full, so I changed the profile setting to delete from the server if mails are older than 60 days. Suddenly, I am now experiencing a couple of glitches. The first is that I get a certificate error when outlook tries it's first send/receive under the relevant profile - "The server you are connected to is using a security certificate that cannot be verified" This continues despite apparently successfully re-importing the certificate. The second glitch is that I get a "Sending reported error (0x8004010F): 'Outlook data file cannot be accessed'" error on send receive. Strangely, it seems to be trying to send/receive twice - once to 'mail@domain', which works, and the second to 'domain' which doesn't. I've tried deleting the profile and re-creating it, pointing to the original .pst file, but still get both errors. Does anybody know how I can resolve these errors? (As a by note, and not that important, more for curiosity, does anybody know why simply changing the delete from server setting against that profile would cause these issues?)

  • Does MySQL log successful or attempted queries?

    - by Nathan Long
    I'm trying to track down a hit-or-miss bug in a web application. Sometimes a request completes just fine; sometimes it hangs and never finishes. I see that Apache now has several requests listed on the server-status page as "sending reply," and that doesn't change. I'm testing on localhost, so there shouldn't ever be more than one. Out of curiosity, I set MySQL to log all queries and I'm tail -fing the log file. When things go OK, I see a pattern like this: 20 Connect root@localhost on dbname 20 Query (some query #1) 20 Query (some query #2) (etc) 20 Quit 21 Connect (etc) When it hangs, I see a pattern like this: 22 Connect root@localhost on dbname 22 Query (some query #1) //nothing happens, so I try the post again 23 Connect root@localhost on dbname 23 Query (some query #1) //nothing happens; try again 24 Connect (etc) Here's my question: is MySQL logging attempted queries, or successful queries? In other words, if the last line I see is query #1, does that imply that query #1 or query #2 is hanging? My guess is that the one I don't see is the problem, because the last one I see looks fine, but maybe the one I don't see is too screwed-up for MySQL to process. Thoughts?

  • Windows 7 mapped drive kicking off OS X users

    - by Collin White
    I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

  • Virtual Machine Network Architecture, Isolating Public and Private Networks

    - by Mark
    I'm looking for some insight into best practices for network traffic isolation within a virtual environment, specifically under VMWARE ESXi. Currently I have (in testing) 1 hardware server running ESXi but i expect to expand this to multiple pieces of hardware. The current setup is as follows: 1 pfsense VM, this VM accepts all outside (WAN/internet) traffic and performs firewall/port forwarding/NAT functionality. I have multiple public IP addresses sent to the this VM that are used for access to individual servers (via per incoming IP port forwarding rules). This VM is attached to the private (virtual) network that all other VMs are on. It also manages a VPN link into the private network with some access restrictions. This isn't the perimeter firewall but rather the firewall for this virtual pool only. I have 3 VMs that communicate with each other, as well as have some public access requirements: 1 LAMP server running an eCommerce site, public internet accessible 1 accounting server, access via windows server 2008 RDS services for remote access by users 1 inventory/warehouse management server, VPN to client terminals in warehouses These servers constantly talk with each other for data synchronization. Currently all the servers are on the same subnet/virtual network and connected to the internet through the pfsense VM. The pfsense firewall uses port forwarding and NAT to allow outside access to the servers for services and for server access to the internet. My main question is this: Is there a security benefit to adding a second virtual network adapter to each server and controlling traffic such that all server to server communication is on one separate virtual network, while any access to the outside world is routed through the other network adapter, through the firewall, and on the the internet. This is the type of architecture i would use if these were all physical servers, but i'm unsure if the networks being virtual changes the way i should approach locking down this system. Thank you for any thoughts or direction to any appropriate literature.

  • Configured Samba to join our domain, but logon fails from Windows machine

    - by jasonh
    I've configured a Fedora 11 installation to join our domain. It seems to join successfully (though it reports a DNS update failure) but when I try to access \\fedoraserver.test.mycompany.com I'm prompted for a password. So I enter adminuser and the password and that fails, so I try test.mycompany.com\adminuser and that too fails. What am I missing? EDIT (Update 9/1/09): I can now connect to the machine and see the shares on it (see my response to djhowell's answer) but when I try to connect, I get an error saying The network path was not found. I checked the log entry on the Fedora computer for the computer I'm connecting from (/var/log/samba/log.ComputerX) and it reads: [2009/09/01 12:02:46, 1] libads/cldap.c:recv_cldap_netlogon(157) no reply received to cldap netlogon [2009/09/01 12:02:46, 1] libads/ldap.c:ads_find_dc(417) ads_find_dc: failed to find a valid DC on our site (Default-First-Site-Name), trying to find another DC Config files as of 9/1/09: smb.conf: [global] Workgroup = TEST realm = TEST.MYCOMPANY.COM password server = DC.TEST.MYCOMPANY.COM security = DOMAIN server string = Test Samba Server log file = /var/log/samba/log.%m max log size = 50 idmap uid = 15000-20000 idmap gid = 15000-20000 windbind use default domain = yes cups options = raw client use spnego = no server signing = auto client signing = auto [share] comment = Test Share path = /mnt/storage1 valid users = adminuser admin users = adminuser read list = adminuser write list = adminuser read only = No I also set the krb5.conf file to look like this: [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = test.mycompany.com dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h forwardable = yes [realms] TEST.MYCOMPANY.COM = { kdc = dc.test.mycompany.com admin_server = dc.test.mycompany.com default_domain = test.mycompany.com } [domain_realm] dc.test.mycompany.com = test.mycompany.com .dc.test.mycompany.com = test.mycompany.com [appdefaults] pam = { debug = false ticket_lifetime = 36000 renew_lifetime = 36000 forwardable = true krb4_convert = false } I realize that there might be an issue with EXAMPLE.COM in there, however if I change it to TEST.MYCOMPANY.COM then it fails to join the domain with a preauthentication failure. As of 9/1/09, this is no longer the case.

  • Setting Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from newly mounted drives

    - by galacticninja
    How do I set Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from external hard drives and TrueCrypt-mounted volumes? I remember in Windows XP, I can set a percentage of total disk space that will automatically be used as storage capacity for deleted files by the Recycle Bin, and this will be applied to all external HDs or TC-mounted volumes. Windows 7 defaults to the 'Don't move files to the Recycle Bin. Remove files immediately when deleted' setting for newly mounted external HDs and TC mounted volumes. Since I am expecting deleted files to go to the Recycle Bin, sometimes this causes an 'Oops' when I delete files in external hard drives or TC mounted volumes, as Windows does not move deleted files to the Recycle Bin, but just deletes the files permanently. I have to remember to manually set a custom Recycle Bin storage space for each new drive that is mounted by Windows to avoid this issue. I only use and mount TrueCrypt file containers, not drives. I also don't mount TrueCrypt file containers as removable drives. ('Mount volume as removable medium' is unchecked in Mount Options.) In my $Recycle.Bin > Properties > Security settings, 'System' and 'Administrators' are already set to 'Full Control', while 'Users' only have 'Special Permissions' checked in gray. There are no other groups. I haven't changed or edited anything in these settings. I am using Windows 7 Ultimate.

  • How do I secure Sql Server 2008 R2

    - by Mark Tait
    I have both a dedicated and a VPS (from Fasthosts) virtual server - the web sites/applications I run on these, access Sql Server stored on the same web server. Until now, I have logged onto Sql Server on both the deidicated and VPS server, from Sql Server Management Studio - until I noticed in my server application logs, multiple attempts to logon to Sql Server using the 'sa' username, but failed password. So someone/bot is trying hard (repeatedly every couple of hours, for approx 20 attempts during each instance) to log on... so obviously I have to lock down access to Sql Sever remotely. What I have done is gone into Configuration Manager, and in Sql Server Network Configuration - Protocols for Sql2008 and also in Sql Native Client 10.0 Configuration - Client Protocols - I have diabled Named Pipes, TCP/IP (and VIA by default). I have left Shared Memory enabled. I also disabled in Sql Server Services, the Sql Server Browser. Now the only way I can manage the databases on these servers, is by logging on to them via Remote Desktop. Can anyone confirm if this is the correct way of stopping anyone maliciously logging on to Sql Server? (I'm not a DBA or security expert - and there are hundreds of articles advising all different ways - but I was hoping for the experts here to confirm, or otherwise, if what I've done is correct) Thank you, Mark

  • How do I set up a Windows NFS share so that I can view it's contents on Linux?

    - by hewhocutsdown
    My NFS server is a Windows XP SP3 box with the Microsoft Windows Services for Unix installed. I have a share configured under C:\NFS with the share name NFS and ANSI encoding. Anonymous access is enabled, with the anon UID/GID set to 0/0. Additionally, I've set ALL MACHINES to Read-Write, and checked the checkbox to Allow root access. My first NFS client is a Ubuntu 10.04 box, with nfs-common installed. Running sudo mount -t nfs 1.1.1.1:/NFS /home/user/NFS succeeds, but when I attempt to view the folder (even as root), it tells me that I do not have the permissions necessary to view the contents of the folder. My second NFS client is an IBM iSeries box running OS/400 V5R3. I used the mount command below: MOUNT TYPE(*NFS) MFS('1.1.1.1:/NFS') MNTOVRDIR('/PARENT/NFS') OPTIONS('rw,nosuid,retry=5,rsize=8096,wsize=8096,timeo=20,retrans=2,acregmin=30,acregmax=60,acdirmin=30,acdirmax=60,soft') CODEPAGE(*BINARY *ASCII) which also mounts successfully. Attempting to WRKLNK '/PARENT/NFS' and use Option 5 to enter the directory yields a Not authorized to object error - even though I am a security officer with the *ALLOBJ special authority. My gut says that it's a problem with the Windows share, but I don't know what it could be. Do you have any suggestions?

  • IP-dependent local port-forwarding on Linux

    - by chronos
    I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

  • Windows : Map-a-network-drive to a remote Shared-Folder (on QNAP NAS) using OpenVPN

    - by spelltox
    Provided my lack of networking knowledge, I've been struggling with this issue for quite a few days now : I have a QNAP-TS212 NAS on which i've created a shared-folder (mostly excel files). All the computers in the local network (windows) are able to access it without any problem. Now, i want to access that shared-folder remotely (windows client), so : I enabled OpenVPN (and PPTP) in QNAP admin. Installed OpenVPN on the remote client. Applied the configuration file that the QNAP generated - Configuration (openvpn.ovpn) : client dev tun script-security 3 proto udp remote ***MY_WAN_IP*** 1194 resolv-retry infinite nobind ca ca.crt auth-user-pass reneg-sec 0 cipher AES-128-CBC comp-lzo OpenVPN connect successfully from the remote client. Now, here's my problem : I can ping the NAS (got IP 10.8.0.1) from the remote client, But when i try to map-a-network-drive, i don't see the shared folder or the NAS or any of the other computers in the network... I checked - all computers are in "WORKGROUP" workgroup. I'm probably missing some basic knowledge, So - any help would be greatly appreciated ! Many thanks.

  • .NET 2.0 Application now running slow on IIS 7.5

    - by Valien
    I recently moved (and still in testing) an application from a Windows 2003 Server (Physical box) running IIS 6.x to a Windows 2008 R2 Standard (VM) IIS 7.5 server. The application is a .NET framework 2.0 application and is running under a 2.0 App Pool. This site works great except for one thing: Takes forever to get a request back. I've been tracking it with Chrome Inspect Element and it queries the site and can take up to 45 seconds to answer. Now when it does the page(s) render instantly but it's that initial request that's killing it. I see no error logs or issues with the application or Windows Event Viewer or even IIS logs so not sure where to start looking next. Some new changes was that previously the app resided behind a Pix firewall and now is behind a larger network environment in a DMZ zone (and I believe NetScaler is also being used to manage the network). I do not have rights/abilities to look at the network itself but can contact the Data center folks to look deeper into this but I wanted to make sure it's not my application that might be causing the slowdown or IIS. In summary: .NET 2.0 application works great in IIS 6.x Application moved to an IIS 7.5 server and now slow on rendering but when it does render responds back with pages instantly. Edit for solution Found out that it was the SOAP calls that were slowing the site down. In the new datacenter my application cannot request SOAP calls and so they time out after 40-45 seconds or so. Now trying to find out if I can install a proxy server to redirect this...

  • cannot reach munin port on other AWS instance

    - by Amedee Van Gasse
    2 AWS instances, in the same region but different availability zones, one is in regular EC2 and the other is in VPC, both have an Elastic IP, both are 64bit Amazon Linux AMI 2014.03.1. Both are running munin-node. The instance in the VPC is running munin-cron. I have added incoming TCP and UDP port 4949 to the security groups of both instances. On the munin node, I added an allow-line with the IP address (regular expression) of the munin server to /etc/munin/munin-node.conf. I bind munin-node to any interface using host *. Then I did sudo service munin-node restart. Then I ran netstat. $ sudo netstat -at | grep munin tcp 0 0 *:munin *:* LISTEN So the port is open there. On the munin server AND on the munin node: $ nmap AMAZON-IP -p 80,4949 | grep tcp 80/tcp open http 4949/tcp closed munin On the munin node: $ nmap localhost -p 80,4949 | grep tcp 80/tcp open http 4949/tcp open munin So from the outside, the http port is open (Apache is running) but the munin port is closed. The node can't even reach the munin port on it's own public IP address, but it can on localhost. I added port 80 as a sanity check, to be sure that there is network connectivity at all. So what am I overlooking here?

  • Can't Install Win2k8 On KVM - Classic 0x80070013 error

    - by javano
    I am trying to install Win2k8 Std as a KVM guest on Debian Squeeze. As you can see from these screen shots; No drives are detected (I have blanked out a 20GB image for testing) - screenshot1 I am using this driver CD: - screenshot2 I have signed the Win7 driver (I assume this was the most appropriate one?) - screenshot3 I can now see an unpartitioned drive - screenshot4 But I can't create a new partition on here, getting the error code 0x80070013 - screenshot5 I have had this error code before but only on a physical server. If I remember correctly it was complaining because the disks were partitioned as GPT (because it was a server that was being re-purposed) so repartitioning with an MS-DOS table fixed that. This is a blank disk image though. What is wrong here, and how can I correct this? Thank you. UPDATE I have booted the VM with a Gparted-Live disk and formatted this volume with an MS-DOS partitioning scheme, and a single 20GB NTFS file system. Now when I boot the Win2k8 CD, load my drivers, I get a different error. As you can see at the bottom of screenshot6 "Windows cannot be installed on this hard drive space. Windows must be installed to a partition formatted as NTFS". Clicking format produces the error (0x80004005) on the screen, so I think this is still a driver issue because Windows can see the drive but not interact with it properly. Is that insane thinking?

  • Disadvantages of enabling 'Low Fragmentation Heap' LFH on Windows Server 2003?

    - by James Wiseman
    I've been investigating an issue with a production Classic ASP website running on IIS6 which seems indicative of memory fragmentation. One of the suggestions of how to ameliorate this came from Stackoverflow: How can I find why some classic asp pages randomly take a real long time to execute?. It suggested flipping a setting in the site's global.asa file to 'turn on' Low Fragmentation Heap (LFH). The following code (with a registered version of the accompanying DLL) did the trick. Set LFHObj=CreateObject("TURNONLFH.ObjTurnOnLFH") LFHObj.TurnOnLFH() application("TurnOnLFHResult")=CStr(LFHObj.TurnOnLFHResult) (Really the code isn't that important to the question). An author of a linked post reported a seemingly magic resolution to this issue, and, reading around a little more, I discovered that this setting is enabled by default on Windows Server 2008. So, naturally, this left me a little concerned: Why is this setting not enabled by default on 2003, or If it works in 2008 why have Microsoft not issued a patch to enable it by default on 2003? I suspect the answer to the above is the same for both (if there is one). Obviously, we're testing it in a non-production environment, and doing an array of metrics and comparisons to deem if it does help us. But aside from this I'm really just trying to understand if there's any technical reason why we should do this, or if there are any gotchas that we need to be aware of.

    My Ubuntu 8.10 crashed due to the overheating problem of the CPU when I am opening some directory and intend to do some file transfer under Nautilus. After reboot, under gnome, all the files cannot be removed, their properties cannot be viewed and they can only be opened, although all are still fine under terminal. I was wondering why is that and how can I fix it? Thanks and regards UPdate $ cat /etc/mtab /dev/sda7 / ext3 rw,relatime,errors=remount-ro 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0 /proc /proc proc rw,noexec,nosuid,nodev 0 0 sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0 varrun /var/run tmpfs rw,nosuid,mode=0755 0 0 varlock /var/lock tmpfs rw,noexec,nosuid,nodev,mode=1777 0 0 udev /dev tmpfs rw,mode=0755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0 devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0 fusectl /sys/fs/fuse/connections fusectl rw 0 0 lrm /lib/modules/2.6.27-15-generic/volatile tmpfs rw,mode=755 0 0 /dev/sda8 /home ext3 rw,relatime 0 0 /dev/sda2 /windows-c vfat rw,utf8,umask=007,gid=46 0 0 /dev/sda5 /windows-d fuseblk rw,allow_other,blksize=4096 0 0 securityfs /sys/kernel/security securityfs rw 0 0 binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0 gvfs-fuse-daemon /home/tim/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,user=tim 0 0

  • Backup plan for linux webserver in small business?

    - by radman
    Hi, I am currently in the process of writing a backup plan for the webserver in use by my business. I am very new to this area and have a few ideas about how things should work but am unsure of what tools to use and what sort of restore process is appropriate. I'm looking for something relatively simplistic and it doesn't have to be 100% paranoid just enough to give me a reliable backup. Speed is not of the essence and there is not going to be a live fallback in place. The backup will be onto a single hdd that will be stored onsite (no option for offsite as yet). Backups will be taking place weekly. I am constrained by both time and money which is why I'm aiming for a good enough solution. Is taking an image of the webserver system drive periodically and using that as the backup appropriate? Should I be testing that the backups restore correctly every time that I perform one? This is a bit broad but what setup would you use if you were in my place, given the services I am running? Should I add additonal machines and split the services? Any advice is much appreciated! See below for server details Webserver Platform Linux Ubuntu server Running mail-server svn-server mediawiki wordpress apache-webserver Hardware single 500gb sata drive Architecture Single machine behind router (with firewall) accessible to the internet.

  • mount error 5 = Input/output error

    - by alharaka
    I am running out of ideas. After a long period of testing this morning, I cannot seem to get this to work, and I have no idea why. I want to mount a Windows SMB/CIFS share with a Debian 5.0.4 VM, and it is not cooperating. This the command I am using. debianvm:/home/me# whoami root debianvm:/home/me# smbclient --version Version 3.2.5 debianvm:/home/me# mount -t cifs //hostname.domain.tld/share /mnt/hostname.domain.tld/share --verbose -o user=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD/username mount.cifs kernel mount options: unc=//hostname.domain.tld\share,ip=10.212.15.53,domain=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD,ver=1,rw,user=username,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,pass=*********mount error 5 = Input/output error Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) debianvm:/home/me# The word on the nets has not been very specific, and unfortunately it is almost always environment-specific. I receive no authentication errors. I have tried mount -t smbfs and mount -t cifs, along with smbmount and such. I get the same error before. I doubt it is a problem with DNS resolution, because logging shows the correct IP address. dmesg | tail -f no longer shows authentication errors when I format the domain and username accordingly. I have played a little with iocharset=utf8, file_mode, and dir_mode as described here. That did not help either. I have also tried ntlm and ntlmv2 assuming it might be a minimum auth method problem, but not forcing sec=ntlmv2 it can still authenticate without errors anymore. smbclient -L hostname.domain.tld -W SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD -U username correctly lists all the shares and shows it as the following. Domain=[SUBADDOMAIN] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] Sharename Type Comment --------- ---- ------- IPC$ IPC Remote IPC ETC$ Disk Remote Administration C$ Disk Remote Administration Share Disk Connection to hostname.domain.tld failed (Error NT_STATUS_CONNECTION_REFUSED) NetBIOS over TCP disabled -- no workgroup available I find the last line intriguing/alarming. Does anyone have any pointers!? Maybe I misread the effin manual.

  • Nginx + PHP-FPM Too Many Resources

    - by user3393046
    My Server has the following Specs CPU: 6 Cores Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz RAM: 32 GB I have a problem with nginx+php-fpm. They are taking too many resources for an unknown reason. Even if i restart the nginx + php-fpm the start up processes will use many resources. My nginx Config is the following: user nginx; worker_processes auto; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_rlimit_nofile 300000; events { worker_connections 6000; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } My php-fpm pool config is the following [www] user = nginx group = nginx listen = /var/run/php5-fpm.sock listen.owner = nginx listen.group = nginx listen.allowed_clients = 127.0.0.1 pm = ondemand pm.max_children = 1500; pm.process_idle_timeout = 5; chdir = / security.limit_extensions = .php I'm using on pm.ondemand since my website has to support many concurrent connections at the same time and i was unable to to it with dynamic/static. I guess this isnt the problem because as i said earlier when i restart nginx+php-fpm at the same time, they are taking too much resources without any request. Here is the screenshot with the CPU Usage http://s28.postimg.org/v54q25zod/Untitled.png

  • Windows Server 2012 Hyper-V very slow

    - by Matt Taylor
    I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

  • Is USB supported in safe mode on XP?

    - by Hugh Allen
    According Microsoft, "Universal Serial Bus Devices Do Not Work in Safe Mode" under XP. However, in my testing this is incorrect. USB keyboards, mice and flash drives seem to work fine in safe mode (I made sure the BIOS was not providing support). This makes sense because a failure of a standard input device would be, in Microsoft parlance, a "bad user experience". So, Is USB supported in safe mode on XP? If your answer is no (agreeing with Microsoft), please provide a test case, preferably in a virtual machine, where a standard HID keyboard or mouse fails. Please state hardware / BIOS / OS configuration. Note that you will need a PS/2 keyboard attached in addition to your USB device(s) in order to use the boot menu. Virtual machine software usually emulates a PS/2 keyboard. Alternatively, you could add the /safeboot switch to boot.ini. If your answer is yes, please provide a link to some supporting documentation (either from Microsoft or someone authoritative). Your answer might be "devices X, Y and Z are supported but nothing else", in which case also give a link.
