• Sticky sessions not sticky on coldfusion cluster

  - by GreatSeaSpider

  we're trying to deploy a legacy coldfusion site onto a new CF8 cluster. The cluster consists of three cf instances running under JRUN4 on a single windows 2008 server. I've got the cluster set to not replicate sessions, and sticky sessions turned on. each instance is set to use J2EE session variables. The application tag for the site has: sessionmanagement="Yes" setclientcookies="Yes" setdomaincookies="Yes" when each instance starts... no errors are reported in the instance log and they join the cluster without any issues. though the intances do have: 16/10 08:31:25 info SessionReplicationService successfully joined a JINI lookup service (assigned JINI-ID .....) and 16/10 08:31:25 info Clusterable service SessionReplicationService discovered a SessionReplicationService peer on a JRun server named "xxxx" on host xxxx which is interesting since session replication is definately off, is the SessionReplicationService responsible for sticky sessions aswell? thats enough background, the problem is that the sticky sessions appear to simply not work, each request is bounced to a different instance, and it seems as if the sessions are being lost on each instance anyways? As soon as the cluster is down to a single instance, the web app works exactly as expected and the sessions seem fine. has anybody got any ideas for me? i've been trawling the web and I cant seem to find any answers.

• Windows XP SP3 Keyboard stops working

  - by Kevin K

  Here's the strangest thing I have yet to see in 20+ yrs of computer repairs. My in-laws Windowsx XP SP3 has stopped recognizing keyboards. The keyboards work fine in the BIOS, during the boot select process to boot normally, etc. but once Windows comes up it will not recognize any USB keyboard. The USB mouse works fine, have tried different USB ports, different keyboards, etc. nothing works. I can log into the machine via VNC and use the remote keyboard just fine, but not connected locally. Tried a system restore, it says nothing changed. I am about to just re-install Windows at this point, except I am afraid it will happen again. I have googled for this and it is not unheard of, but I have not found any solution other than nuking it. Anyone have any ideas? I have re-installed the USB drivers for the M/B. Gone into devices and deleted them for a re-install, etc. Keyboard works off a Linux live boot CD, and in the BIOS setup so it is not a hardware issue, and I have tried a few keyboards all of which I know are good and work fine on other systems.

• Problem setting command-line console resolution. vbeinfo in grub2 does not report all resolutions

  - by Kent

  I have a Asus EEE PC 1005P which I installed a Command-line system on using the Alternate Installer CD of Ubuntu Lucid Lynx. Altough I think this is a general linux and grub2 question. I do not have (or want) the X Window System installed. I want to change my console screen resolution (not inside X) to 1024x600. But it isn't reported when I use vbeinfo inside grub: grub> vbeinfo VBE info: version: 3.0 OEM software rev: 1.0 total memory: 8128 KiB List of compatible video modes: Legend: P=Packed pixel, D=Direct color, mask/pos=R/G/B/reserved 0x112: 640 x 480 x 32 Direct, mask: 8/8/8/8 pos: 16/8/0/24 0x114: 800 x 600 x 16 Direct, mask: 5/6/5/0 pos: 11/5/0/0 0x115: 800 x 600 x 32 Direct, mask: 8/8/8/8 pos: 16/8/0/24 0x101: 640 x 480 x 8 Packed 0x103: 800 x 600 x 8 Packed 0x111: 640 x 480 x 16 Direct, mask: 5/6/5/0 pos: 11/5/0/0 Configured VBE mode (vbe_mode) = ox101 grub> Relevant parts of sudo lspci -v: ... ... 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller Subsystem: ASUSTeK Computer Inc.

• IIS serving static content gives 503 at random

  - by Steffen

  We're having a few issues with our image server. It's a Win 2008 running IIS 7.5 and it only serves static content: images. It has run without issues for quite a while, until recently when we disabled Output Caching, as we noticed having it enabled meant it sent no-cache host-headers to the clients (forcing them to fetch the images from the server every time) We've read quite a bit about it, and it seems IIS just works that way - either you use Output Caching or you get to use cache host-headers. Anyway having disabled the Output Cache, we now experience random 5 minutes intervals, where all requests just get a 503 Service Unavailable. During this period the "Files cached" performance counter staggers (neither increased nor decreased) and after the period all caches are flushed. You might find it weird I talk about caching, since we disabled Output Caching. The thing is we changed the ObjectTTL parameter in registry, so we cache files for 3 minutes (which has worked very well, our Disk I/O dropped significantly) So even with Output Caching disabled, we're still caching plenty of files - if we could just get rid of the random 503 it'd be perfect :-D We don't get any messages in the Windows event log during these 503 intervals, so we're pretty stumped as to what to do. Any ideas are very welcome :-)

• Apache & SVN on Ubuntu - Post-commit hook fails silently, pre-commit hook “Permission Denied”

  - by 113169587962668775787

  I've been struggling for the past couple days to get post-commit email notifications working on my SVN server (running via HTTP with Apache2 on Ubuntu 9.10). SVN commits work fine, but for some reason the hooks are not being properly executed. Here are the configuration settings: - Users access the repo via HTTP with the apache dav_svn module (I created users/passwords via htpasswd in a dav_svn.passwd file). dav_svn.conf: <Location /svn/repos> DAV svn SVNPath /home/svn/repos AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user </Location> I created a post-commit hook file that writes a simple message to a file in the repository root: /home/svn/repos/hooks/post-commit: #!/bin/sh REPOS="$1" REV="$2" /bin/echo 'worked' > ${REPOS}/postcommit.log I set the entire repository to be owned by www-data (the apache user), and assigned 755 permissions to the post-commit script when I test the post-commit script using the www-data user in an empty environment, it works: sudo -u www-data env - /home/svn/repos/hooks/post-commit /home/svn/repos 7 But when I commit on a client machine, the commit is successful, but the post-commit script does not seem to be executed. I also tried running a simple script for the pre-commit hook, and I get an error, even with an empty pre-commit script: "Commit failed (details follow): Can't create null stdout for hook '/home/svn/repos/hooks/pre-commit': Permission denied" I did a few searches on Google for this error and I presume that this is an issue with the apache user (www-data) not having adequate permissions, specifically to execute /dev/null. I also read that the reason post-commit fails silently is because that it doesn't report with stdout. Anyway, I've also tried giving the apache user (www-data) ownership of the entire repository, and edited the apache virtualhost to allow operations on the server root, and I'm still getting permission denied /etc/apache2/sites-available/primarydomain.conf <Directory /> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> Any ideas/suggestions would be greatly appreciated! Thanks

• Cisco SG200 vlan issue in ESXi VSA cluster

  - by George

  I have three Cisco SG200-26 switches, and I also have two ESXi hosts that I have connected like shown in the below "best practice" map by VMware: http://communities.vmware.com/servlet/JiveServlet/previewBody/17393-102-1-22458/VSA_networking_map.pdf Even though I created the VLANs in the SG200 and I set the two VLANs (508 and 608) as allowed for these untagged ports (where my ESX NIC's are connected), I can not ping from host 1 to host 2 when configuring the NIC's to use 608 VLAN. Am I missing something? my IP's are all in the 192.168. range, and the only reason I need the VLANs is to isolate the traffic of VSA back-end internally, only the two hosts will be using the VLANs. So I think I do not have to create virtual interfaces on my router since that's the case, is my understanding correct? Also sending my switch config screenshot below.. all 3 switches have the latest firmware (it seems these were originally linksys and got rebranded as cisco after the acquisition) http://img31.imageshack.us/img31/2503/switch.gif Any ideas what to change on the Cisco SG200 to make this work , would be appreciated! The second VLAN (608) only needs two IP's: 192.168.0.1 and 192.168.0.2 The first VLAN (508) will have about 15 IP's for ESXi Management and VSA cluster service, I could use either 192.168.1.xx or 10.0.1.xx The rest of my network (about 50 clients) is in 192.168.1.xx range VMware also states that the VLAN protocol on the physical switch must be 802.1Q, not ISL, anyone knows which of the two my SG200-26 uses? In addition to that, the only requirement from VSA is that my two hosts: -Are in the same subnet. -Have static IP addresses set. -Have the same Default Gateway configured. If I need inter-vlan routing for this, I suppose I have to create virtual interfaces on my sonicwall, and assign an IP for each VLAN, and then set routes between them? Thank you for your time!

• How to verify PostgreSQL 9 has installed correctly on a CentOS server?

• Not recognizing second monitor after hibernate (Windows 7, Dell D630 laptop)

  - by Brooks Moses

  I have a Dell Latitude D630 laptop which I've recently updated to Windows 7 64-bit. (The Dell site confirms that it's Windows-7-compatible.) Normally it lives in a docking station with a second monitor connected to the DVI port on the docking station, and I use the second monitor in a multi-monitor configuration with the laptop screen. Sometimes I undock the laptop and use it separately. Here's the problem: If I hibernate the laptop while undocked, and then power it back up in the docking station, it does not recognize the second monitor. By which I mean that not only does it not share the desktop onto the second monitor, but if I go into the control panel for display settings and press "Detect", it does not even detect the existence of the second monitor. I can tell it to "use the VGA port anyway" for a second monitor, but the monitor is connected to a DVI port on the docking station, so that doesn't do anything useful. If I entirely reboot the laptop while it's connected to the docking station, it has no problem recognizing the second monitor and using it. But then, if I hibernate, undock, de-hibernate while undocked and rehibernate, and then re-dock and de-hibernate, it's back to not recognizing the second monitor again. I'm reasonably certain that this is not a limitation of the hardware; this worked fine on Windows XP. I'm currently using the Windows 7 driver for my video card. I attempted to use the video driver from the Dell website for this laptop, but Dell only provides Vista 64-bit drivers, not Windows 7 64-bit drivers. Their "Windows 7 compatibility" page suggests that the Vista drivers should work, but when I attempted to install the driver, it gave me a "this operating system not supported" error and refused to install. Any further ideas?

• Leopard Network Shares and browsing are unreliable

  - by EvilChookie

  I have two macs, running Leopard 10.5.8. One is the 13" MBP connected via WiFi, and the other is a 24" 2008 iMac, connected via ethernet. There are at least another 6-10 machines (windows and mac) awake on the network (with shares) at any given time, yet there are plenty of times where I cannot see any devices/shares in either my "Shared" section in Finder, nor can I see any computers in "Network" in Finder. Restarting doesn't help. I've restarted all the networking gear in the house to no avail. Our network is a series of gigabit switches connected to a D-Link gaming router. I believe we use OpenDNS, and our provider is Cox. I hate having to use "Go - Connect to Server" to browse to commonly used file shares (by IP). I'd like to know why my shares do not always and consistently appear in Leopard. Edit: I ran OnyX this morning, and performed the cleaning and maintenance operations (including disk permissions) on both my Macs, and at least one of my macs has started showing network devices again. (the other is still going). No idea how long this will last. Any ideas as to what is causing this issue, and how to prevent it? Edit 2: Aaaand there the shares go again. So running OnyX is not a permanent or reliable fix for this issue. Edit 3: After a clean reinstall and update, network shares are still unreliable. The SMBClient command mentioned in comments shows me the information it's supposed to show, but the shares do not appear in the shared section. They'll also vanish at random and reappear at random throughout the day.

• Embedded Spotlight does not function in Outlook 2011

  - by syntaxcollector

  I have a rather strange problem. I manage a network of about 35 Mac, and we all recently switched from Mail.app to Outlook 2011 (Please don't debate this, I've already had this conversation ad nauseum) We are using network home directories (NHD) server from a Windows file server over the SMB protocol. The problem I'm having is Spotlight does not function inside of Outlook. But ONLY inside of Outlook. The global Spotlight can find all email and contacts with Outlook, but the embedded Spotlight cannot. As a test, I took one of my users and switched them from a network home directory to a portable home directory (PHD) (this means the home folder was copied to the local hard drive). This resulted in a working Spotlight within Outlook, as soon as I switched the user back to an NHD, however, it stopped working. I have already tried erasing the Spotlight index and killing the process to force re-indexing. I have exhausted all Spotlight troubleshooting, and since the global is working that is obviously not the issue. I believe it has something to do with the Spotlight plugin Microsoft wrote that is located in /Library/Spotlight. Any ideas?

• Cannot open files in Visual Studio but in Delphi and Notepad

  - by Andrew J. Brehm

  About an hour ago Visual Studio 2008 decided that it cannot find files any more. This is on 64 bit Windows Vista. When I right-click on a text file (source code or otherwise) and select "open with" and "Visual Studio 2008", I get the following error (example): Windows cannot find 'C:\Users\ajbrehm\Documents\Visual Studio 2008\Projects\Hello Prism\Hello Prism\Main.pas'. Make sure you typed the name correctly, and then try again. When I right-click the same file and select "open with" and "Delphi 2010" or "Notepad" (both other options available for text files on my system), the file opens correctly. Oddly enough when the file is part of a Visual Studio project and I open the project itself with Visual Studio (this works), I can open the file from within Visual Studio. Any ideas what might be going on? This started about an hour after I made a complete backup of my Vista VM and after I installed IIS 7, SQL Express, and Sourcegear Vault. The first files I noticed couldn't be opened in Visual Studio any more where Pascal source files in checked-outed folders from Vault. And Vault also seems to be unable to see one of the sources files and claims they don't exist. I found out about Visual Studio not opening ANY files any more when I tried to recreate the file Vault refused to see. Update: I just checked. Another user, "administrator", can still open text files with Visual Studio 2008. Both users have administrator rights. Update: I just restored the hours-old backup. Same problem. Apparently whatever triggered this happened before the install of IIS 7 and SQL Express. Never noticed it before.

• Word documents very slow to open over network, but fine when opened locally - on one machine

  - by Craig H

  Windows XP, Word 2003, patched. The issue is happening with several Word documents stored on a network drive. The Word documents are clearly a bit wonky (i.e. one is 675k, but if you copy everything but the last paragraph marker into a new document, the new document is only 30k). But that's only part of the problem. On one weird machine, and one machine only, it takes ~20 seconds to open these Word documents from the network drive. Copy the file to C: on that werid machine? Opens immediately. Go to other machines (that are very similar - same patch level, etc.) and open the same document from the network? Opens immediately. Delete normal.dot? 20 seconds. Login with a different user on the weird machine? 20 seconds. Plug wonky machine into a different network port? 20 seconds. So the problem appears to be hardware related (i.e. wonky internal NIC) or related to a setting that is not profile specific. Any ideas? "Scrubbing" all the documents isn't ideal for several reasons. This is driving me nuts because I swear I ran into this before many years ago and eventually figured it out. But I appear to have lost my notes.

• Disabling mouse acceleration in Mac OS X

  - by aib

  I've been looking for a solution to the unusable mouse problem in Mac OS X for ages. I've tried a gazillion programs and fiddled with every setting there is or there can be added. So far, I haven't found a way to get linear mouse response in Mac OS X. At this point I'm seriously considering installing another operating system. But before I do that, or go hacking around OS binaries, maybe someone here has a solution? I want linear mouse response. I want high sensitivity. I like my touchpad acceleration and would like to keep it if possible. Any ideas? P.S. I've been at this for a long time, I'll probably have already tried the most popular answers. I'm running Mac OS X 10.6.5 on a MacBook Pro. I don't use a particular brand of mouse. I'm not looking for any commercial solutions. I've tried: Mouse Acceleration Preferences Pane, the Snow Leopard version of which can get me close to a linear response, but at the cost of tracking speed (sensitivity). Answers on this question: Make Mac OS X mouse acceleration more Windows-like About every code snippet I found via Google.

• High load average, low CPU and IO (Centos 5.7)

  - by Ben

  A Drupal 7 site with CiviCRM, after running smoothly for a year on a 1&1 VPS suddenly became unresponsive. Now pages eventually load, but can take more than a minute. Looking at resource use in Virtuozzo, the load average carries a warning, and has remained above 1. While I understand this isn't particularly high, this is a change from when the site was working. Here is a typical snapshot of top: top - 03:10:32 up 3:21, 1 user, load average: 1.16, 1.22, 1.30 Tasks: 43 total, 1 running, 42 sleeping, 0 stopped, 0 zombie Cpu(s): 0.1%us, 0.1%sy, 0.1%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2097152k total, 1015112k used, 1082040k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached CPU idle level never seems to go much below 70%. wa is virtually always at 0. There appears to be lots of free memory.

• Should I use /etc/bind/zones/ or /var/cache/bind/?

  - by nbolton

  Each tutorial seems to have a different opinion on this. For my ISC BIND zones, should I use /etc/bind/zones/ or /var/cache/bind/? In the last install, I used /var/cache/bind/ but only because I was guided to do so; however I just spotted a pid file in there for this new Debian install, so I figured that using the "working directory" to store zone files probably wasn't the best idea. It seems that many admins use this so they don't have to type the full path when declaring a new zone. For example: file "/etc/bind/zones/db.foobar.com"; Instead of: file "db.foobar.com"; Is obviously easier to type, but is it good or bad practice? Some may also suggest setting the working directory to /etc/bind/zones: options { // directory "/var/cache/bind"; directory "/etc/bind/zones"; } ... but something tells me this isn't good practice, since the pid file would be created there I assume (unless it's just in /var/cache/bind by coincidence). I took a look at the manpage but it didn't seem to say what the directory option was for, any ideas exactly what it was design for?

• Reloading NAT configuration on a running VMWare Server 2.0.2

  - by Jonathan Clarke

  I have a server running VMWare Server 2.0.2. The host is Debian Lenny. I have 15-20 virtual machines running, all attached to a single NAT network (named vmnet8). I have configured VMWare's NAT (the vmnet-natd daemon) to forward some incoming to ports to one of the VMs, since it hosts some publicly accessible services. I did this via the file /etc/vmware/vmnet8/nat/nat.conf by adding lines like the following: 80 = 192.168.100.100:80 This works great, I can reach the web server on the VM at 192.168.100.100 by connecting to the host's IP address. Sometimes, I need to add port redirections to this NAT configuration. So, I add a line to the configuration file. Now for the question. How do I make the natd process take this new configuration into account? Clearly, restarting the host machine does take it into account, and the newly added port is forwarded. However, this is not an option on this server, so how should one do this without restarting the whole host? Thanks for any ideas!

• port forwarding with VirtualBox

  - by Argh

  I have a virtualbox VM running ubuntu. The Ubuntu guest is running a web server which listens on port 3000 (http://127.0.0.1:3000) The host machine is windows vista. I have configured port forwarding using VBoxManage. If I query the config using VboxManage getextradata "MyMachine", I get Key: GUI/AutoresizeGuest, Value: on Key: GUI/Fullscreen, Value: off Key: GUI/LastCloseAction, Value: shutdown Key: GUI/LastWindowPostion, Value: 9,34,640,529,max Key: GUI/MiniToolBarAlignment, Value: bottom Key: GUI/MiniToolBarAutoHide, Value: off Key: GUI/SaveMountedAtRuntime, Value: yes Key: GUI/Seamless, Value: off Key: GUI/ShowMiniToolBar, Value: yes Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/GuestPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/HostPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/Protocol, Value: TCP This looks like it should work... However when I try to access the web server from the host machine (windows box) I dont get a response. I ran a netstat on the windows box and nothing appears to be listening on port 3000 which explains why forwrding isnt working. Note that I have already tested with my firewall switched off... The version of VirtualBox I am using is 3.1.4 Any ideas?

• VSFTPD does not allow upload with virtual users

  - by Mr. Squig

  I am attempting to setup VSFTPD with virtual users on a server running Ubuntu 12.04. I have configured the server to allow for virtual users to login, but I am having trouble getting it to allow uploads. My vsftpd.conf is as follows: listen=YES anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 anon_upload_enable=YES dirmessage_enable=YES use_localtime=YES xferlog_enable=YES connect_from_port_20=YES chroot_local_user=YES virtual_use_local_privs=YES guest_enable=YES guest_username=virtual user_sub_token=$USER local_root=/var/www/$USER hide_ids=YES secure_chroot_dir=/var/run/vsftpd/empty pam_service_name=vsftpd rsa_cert_file=/etc/ssl/private/vsftpd.pem /etc/pam.d/vsftpd contains: auth required pam_pwdfile.so pwdfile /etc/vsftpd.passwd crypt=hash account required pam_permit.so crypt=hash I have two virtual users set up, one of which has the same name as a local user. They each have a directory in /var/www/ owned by 'virtual'. As I understand it, when a virtual user logs in this way they will appear to the system as the user virtual. Using this configuration user can log on, but cannot upload files.

I have a feeling that it is something simple related to permissions. Any ideas?

• Help diagnosing Likewise Open Active Directory authentication problem

  - by purpletonic

  I have two servers which were up until recently authenticating against the companies Active Directory Domain controller. I believe a recent change to the Active Directory administrator password caused the servers to stop authenticating against AD. I tried to add the servers back to the domain using the command: domainjoin-cli join example.com adusername this seemed to work without complaints, but when I try to login via ssh with my domain account, I get an invalid password error. When I run the command: lw-enum-users it prints all of the domain users, and looking up my own account, I see that it is valid and my password hasn't expired. I also ran lw-get-status and received the following: LSA Server Status: Agent version: 5.0.0 Uptime: 0 days 3 hours 35 minutes 46 seconds [Authentication provider: lsa-activedirectory-provider] Status: Online Mode: Un-provisioned Domain: example.com Forest: example.com Site: Default-First-Site-Name Online check interval: 300 seconds \[Trusted Domains: 1\] \[Domain: EXAMPLE\] DNS Domain: example.com Netbios name: EXAMPLE Forest name: example.com Trustee DNS name: Client site name: Default-First-Site-Name Domain SID: S-1-5-24-1081533780-4562211299-822531512 Domain GUID: 057f0239-7715-4711-e64b-eb5eeed20e65 Trust Flags: \[0x001d\] \[0x0001 - In forest\] \[0x0004 - Tree root\] \[0x0008 - Primary\] \[0x0010 - Native\] Trust type: Up Level Trust Attributes: \[0x0000\] Trust Direction: Primary Domain Trust Mode: In my forest Trust (MFT) Domain flags: \[0x0001\] \[0x0001 - Primary\] \[Domain Controller (DC) Information\] DC Name: dc1.example.com DC Address: 10.11.0.103 DC Site: Default-First-Site-Name DC Flags: \[0x000003fd\] DC Is PDC: yes DC is time server: yes DC has writeable DS: yes DC is Global Catalog: yes DC is running KDC: yes [Authentication provider: lsa-local-provider] Status: Online Mode: Local system Anyone got any ideas what might be occurring?

• Openconnect for Cisco VPN doesn't recognize private key file - asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag

  - by Alexander Skwar

  I'm trying to use my Synology DS212 NAS box also act as VPN gateway to my companies VPN. Sadly, they only use Cisco ASA and to complicate stuff even further, we've got to use personal certificates (which is of course more secure, but more complicate to get going…). So I compiled OpenConnect v4.06 from http://www.infradead.org/openconnect/. As a very basic test, I tried to build a connection by manually invoking openconnect, passing along the key and cert files, like so: /lib/ld-linux.so.3 --library-path /opt/lib \ /opt/openconnect/sbin/openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 It fails :( Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Using client certificate '/[email protected]/OU=Company VPN' 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Loading private key failed (see above errors) Loading certificate failed. Aborting. Failed to open HTTPS connection to <ip> Failed to obtain WebVPN cookie When I run the same command with the same cert/key files on a Ubuntu 12.04 box, it works: openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Extra cert from cafile: '/CN=Company AG VPN CA/O=Company AG/L=Zurich/ST=ZH/C=CH' SSL negotiation with <ip> Server certificate verify failed: self signed certificate Certificate from VPN server "<ip>" failed verification. Reason: self signed certificate Enter 'yes' to accept, 'no' to abort; anything else to view: yes Connected to HTTPS on <ip> GET https://<ip>/ […] Well… The error on the NAS is this: 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Any ideas, what's causing this? On Syno, I use OpenConnect 4.06. On Ubuntu, I just compiled and installed to a custom location OpenConnect 4.06 as well. Thanks, Alexander

• One host on a network can't connect to one other host

  - by Max Williams

  I'm on a local network with a few other people. On of the hosts is a virtual machine running in virtualbox on a mac, which has the ip address 192.168.0.35 (the VM that is, not the mac host). Everyone except one guy can connect (ie ping, ssh etc) to that machine. When that one guy tries to ping it he gets Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 which i understand is just how certain mac os's report an unreachable connection. He can ping all the other hosts on the network, ie our computers, and we can all ping the VM fine and connect to it with no problems etc. His ip is 192.168.0.17. I ssh'd onto his machine (as a new user 'anon') and saw the same problems. I can ssh onto the 192.168.0.35 VM as well. From there, i can ping other users, but when i ping the problem guy, it's unreachable that way round as well. He restarted his mac, and was fine for a while. Then, just stopped working again. He's got a different IP to before. Any ideas, anyone? Don't know enough about this stuff to even diagnose the problem. thanks, max

• Apache2/Shibboleth TCP connections stuck in CLOSE_WAIT

  - by RJT

  I run an Apache2 server which uses the Shibboleth daemon (shibd) as federated authentication module. Certain server connections using Shibboleth seem to stick permanently in CLOSE_WAIT state. tcp 38 0 blah.blah:57346 shib.server.:8443 CLOSE_WAIT tcp 38 0 blah.blah:45601 shib.server2:8443 CLOSE_WAIT tcp 38 0 blah.blah:41737 shib.server3:5057 CLOSE_WAIT From what I can find out, CLOSE_WAIT means that when the remote server disconnects, the local application is failing to close the connection, as it should. I suspect shibd is responsible somehow. Needless to say, if enough CLOSE_WAIT connections accumulate, I have a problem. Trying to get rid of the CLOSE_WAIT connections by simply using /etc/init.d/networking restart does not work. In fact networking seems to refuse to close down and restart, and I get a SIOCADDRT: File exists error (ie networking is trying to start without having stopped first). Same problem with ifup -a So I have two questions - one may be easy, and one harder. What's a good way to force networking to restart, and force whatever connections are stuck in CLOSE_WAIT to clear? Any ideas about how to fix shibboleth and force shibd module to behave?

• Can't remotely connect through SQL Server Management Studio

  - by FAtBalloon

  I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

• monitoring a /21 for potential bad guys with snort and port mirroring

  - by Adeodatus

  Hi all, I want/need to start monitoring our network a bit better. Its an odd network in that it comprises 2 /22 public IPs and a slew of private admin IPs. I do have one point in the network where it all comes together and I can turn on port mirroring on the catalyst. From that port, I'd like to turn up a box running various utilities. Snort is high on my list but it'd be nice to also get some networking statistics with something like Netflow. So, what are peoeple's thoughts. I can turn up a box needed for this with a bit of ease. We have the hardware available. What should I run? I'd love to know what kind of nasty things are potentially going on but I'd also like to see statistics on what people are doing on the network so I can better tweak our systems to handle it better and improve performance. I'm open so please, give me some ideas to go along with what I've got.

• Limit Apache 2 Memory Usage

  - by UltraNurd

  I am running a hobby webserver off of an ancient Blue & White G3/300 running Debian PPC Squeeze 2.6.30. The performance is okay for a while after a restart, but it eventually gets more and more bogged down. Right now it's at 76 days uptime, and the main culprit seems to be the memory usage of 10+ apache2 processes. I think I need to lower the values for StartServers, MinSpareServers, and/or MaxSpareServers, but I'm not sure which one to adjust, and there are three sections for each depending on which mpm module is in use. How do I tell which of the following sections I need to change, and what are some reasonable values given that the box has 448 MB physical memory (weird upgrade history of one each 64, 128, and 256 sticks)? <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_event_module> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> There aren't any other instances of StartServers in my apache2.conf, but none of those mpm modules appear in mods-available or mods-enabled. Ideas? Thanks!
