• Tomcat OutOfMemory after switching JVM

  - by Mathias

  I have a Tomcat6 server running on Debian squeeze there are 4 webapps running on it, and an in-JVM ActiveMQ server. It has been running for about a year with the same memorysettings, with openjdk-6. Everything has worked dandy, no issues at all. Now, for various reasons, i need to try out Sun's JDK. So, I installed sun's jvm with standard apt-get apt-get install sun-java6-bin , and switched using update-java-alternatives -s java-6-sun However, when i start tomcat, i get outofmemory, the server won't even start! If i switch back to openJDK, all works fine again. I haven't had any memory issues on this server before, so it feels strange that the server suddenly won't start with sun's JDK. Anybody have any clue as to why this might happen? Have i missed something? I naturally have set heap sizes etc. in tomcat. Currently running with: -Xms256m -Xmx1024m Which as mentioned works in openSDK, outofmemory in sun-jdk... EDIT: server is 64-bit, openJDK and Sun are 1.6.0, both 64-bit JVMs.

• In an environment with multiple WiFi access points, do wireless clients sometimes connect to both at the same time?

  - by Bobby Burgess

  This is more of a curiosity than a problem, but in this new office I have two D-link DAP-2553's connected in a master/slave array (this just means the master keeps certain configuration options aligned with the slave). The network is set to 802.11n-only, and each AP has the same SSID and WPA2 key. The only difference is that they are on different channels (1 and 11). The WiFi network itself is working well. Users can roam around and the signal/speed is fairly consistent. However, I notice that when I look at the 802.11 client list in the web admin page for each of the 2 APs, I see that certain clients are connected to both, for extended periods of time, but I assume they are only passing data through one of them. Not every client is seen on each AP, but at any given time the same MAC address of a WiFi adapter can be associated (and remain associated) with both APs. The client list auto-refreshes every few seconds so I believe I'm looking at the most recent rather than stale information. One of the WiFi adapters that consistently associates with both APs is an Intel Centrino Wireless-N 1030 (laptop chip). Is it part of the WiFi standard that more than one association per WiFi card can be established concurrently on separate APS?

• How to move or delete files from a folder containing 2 million files on an NTFS drive?

  - by Beau

  The issue is that any modification to the directory locks up Explorer indefinitely, though Samba access to other directories still works. I've tried moving files locally and over Samba. Even enumerating the directory to get the list of files locks up the computer indefinitely. I tried using Python's win32file.FindFilesIterator to iterate the files but that also hangs. My idea was to move each file to a different directory (in a directory above the directory we're dealing with) based on its timestamp, so that we'd have at most a thousand or so files in each directory... But since I can't even enumerate the files, that's been a non-starter. If I have to give up and just nuke the directory I'm willing to do that, but a standard delete also hangs indefinitely. I have set these two parameters to increase speed and they also did not help the issue: R:\>fsutil behavior query disablelastaccess disablelastaccess = 1 R:\>fsutil behavior query disable8dot3 disable8dot3 = 1 These are all sequential images that would have run into the 'bug' with 8.3 filenames whereby many similarly named files in one directory can take a long time to compute 8.3 filenames. From what I understand this data is stored in the file system even after disable8dot3 is enabled, so it may still be contributing to the problem. Any ideas?

• Multiple *NIX Accounts with Identical UID

  - by Tim

  I am curious whether there is a standard expected behavior and whether it is considered bad practice when creating more than one account on Linux/Unix that have the same UID. I've done some testing on RHEL5 with this and it behaved as I expected, but I don't know if I'm tempting fate using this trick. As an example, let's say I have two accounts with the same IDs: a1:$1$4zIl1:5000:5000::/home/a1:/bin/bash a2:$1$bmh92:5000:5000::/home/a2:/bin/bash What this means is: I can log in to each account using its own password. Files I create will have the same UID. Tools such as "ls -l" will list the UID as the first entry in the file (a1 in this case). I avoid any permissions or ownership problems between the two accounts because they are really the same user. I get login auditing for each account, so I have better granularity into tracking what is happening on the system. So my questions are: Is this ability designed or is it just the way it happens to work? Is this going to be consistent across *nix variants? Is this accepted practice? Are there unintended consequences to this practice? Note, the idea here is to use this for system accounts and not normal user accounts.

• Windows 7 comments field missing when browsing network

  - by Toymangenie

  I have just purchased three Windows 7 Professional Dell 64-bit PCs for testing prior to upgrading our company’s 120+ PCs from Windows XP Professional. The setup is a standard domain with a Windows Server 2003 32-bit server. We name each PC XP1 to XP150 so that when users join or leave, I don’t have to rename the PC. We use the Description field to allocate the user’s name to each PC. We also have a share set up on each PC using the user’s name. When I browse the network using Windows Explorer in XP, I get a useful display. The left pane showing the PC number and the right pane showing NAME and COMMENTS So, for example I would see: XP01 Fred Bloggs (Each PC on a new row.) The right pane is my main tool for administering the network. I can easily see the PC number and the name of the user. However, in Windows 7, this seems to have been thrown out of the window and replaced with fields that I do not need and in my case always display the same info. "Name", "Category", "Workgroup", "Network Location" In my case the Name column gives the PC number (XP10) etc and all three other columns display identical useless information. So I can’t see who is using XP10. When I am in “help desk” mode, I would naturally ask the user’s name and use my remote desktop client to view their screen. The user isn’t aware of their PC name, so I am finding it impossible to match the user name with a PC number. Any ideas how to overcome this "by design" change to Windows 7?

• Why *do* windows print queues occasionally choke on a print job

  - by Ian

  Y'know they way windows print queues will occasionally stop working with a print job at the head of the queue which just won't print and which you can't delete? Anyone know whats going on when this happens? I've been seeing this since the NT4 days and it still happens on 2008. I'm talking about standard IP connected laser printers - nothing fancy. I support a lot of servers and loads of workstations and see this happen a few times a year. The user will call saying they can't print. When you examine the print queue, which in my case will generally be a server based queue shared out to the workstations, you find a print job which you cannot cancel. You also can't pause it, reinitialize it, nothing. Stopping the spooler is the usual trick and works sometimes. However I occasionally see cases which even this doesn't cure and which a reboot is the only solution. Pause the queue, reboot, when it comes back up the job can then be deleted. Once gone the printer happily goes back to its normal state. No action is ever necessary on the printer. I regard having to reboot as last resort and don't like it. What on earth can be going on when stopping the process (spooler) and restarting it doesn't clear a problem? Its not linked to any manufacturer either. I've seen this on HPs, lexmark, canon, ricoh, on lasers, on plotters.... can't say I ever saw this on dot matrix. Anyone got any ideas as to what may be going on. Ian

• Outlook Signature Broken in Entourage

  - by Eric J.

  Some of our company uses Windows with Outlook 2010, and the rest use Mac with Entourage. When our standard signature line is included in an email that goes to Entourage, the result does not display correctly. It appears that Entourage is mangling the HTML. My working theory is that Entourage encounters inline CSS styles it does not know about and stops processing styles, but I'm really not sure. Question: How can I enter a signature into Outlook 2010 that will render correctly in Entourage? For example, can I specify somehow the exact HTML to use? Here's an example of how the HTML is being changed. Original on Outlook, as received by another Outlook client: <span style='font-size:9.0pt;font-family:"Century Gothic","sans-serif"; color:#1785C5'>My Company<br> </span></b><span class=apple-style-span><span style='font-size:9.0pt; font-family:"Century Gothic","sans-serif";color:#666666'>123 Main St.</span></span><span class=apple-style-span><span style='font-size:9.0pt;font-family:"Century Gothic","sans-serif"; color:#AFAFAF'>&nbsp;</span></span><span class=apple-style-span><span style='font-size:9.0pt;font-family:"Century Gothic","sans-serif";color:#666666'>Suite 100</span></span> Note the use of spans, color #1785C5 and color #666666. Same original email, as displayed in an Entourage client: <span style='font-size:9.0pt;font-family:"Century Gothic","sans-serif"; mso-fareast-font-family:"Times New Roman"'><br> <span style='color:#656565'>My Company<br> 123 Main St Suite 100<br> </span> Note the use of br tags rather than spans, and the color #656565.

• Manipulating IIS7 Configuration with Powershell

  - by John Price

  I'm trying to script some IIS7 setup tasks in PowerShell using the WebAdministration module. I'm good with setting simple properties, but am having some trouble when it comes to dealing with collections of elements in the config files. As an immediate, example, I want to have application pools recycle on a given schedule, and the schedule is a collection of times. When I set this up via the IIS management console, the relevant config section looks like this: <add name="CVSupportAppPool"> <recycling> <periodicRestart memory="1024" time="00:00:00"> <schedule> <clear /> <add value="03:31:00" /> </schedule> </periodicRestart> </recycling> </add> In my script I would like to be able to accomplish the same thing, and I have the following two lines: #clear any pre-existing schedule Clear-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" #add the new schedule Add-WebConfiguration "/system.applicationHost/applicationPools/add[@name='$($appPool.Name)']/recycling/periodicRestart/schedule" -value (New-TimeSpan -h 3 -m 31) That does almost the same thing, but the resulting XML lacks the <clear/> element that is created with via the GUI, which I believe is necessary to avoid inheriting any default values. This sort of collection (with "add", "remove", and "clear" elements) seems to be fairly standard in the config files, but I can't seem to find any good documentation on how to interact with them consistently.

• How can I avoid a few seconds of blank video when using -vcodec copy?

  - by arlomedia

  I'm processing user-uploaded videos on a CentOS web server with ffmpeg. I need to convert each video to a standard size and format, then extract a 30-second sample clip from each video. I want to use the "-vcodec copy" flag in the extraction command to avoid encoding a second time. This command works for my initial conversion: ffmpeg -i uploaded.mov -f mp4 -vcodec libx264 -vpre medium -acodec libfaac -r 15 -b 360k -ab 48k -ar 22050 -s 480x320 formatted.mp4 And this sometimes works for the extraction: ffmpeg -i formatted.mp4 -vcodec copy -acodec copy -ss 0 -t 30 formatted_sample.mp4 However, when I run the extraction command on some videos, the extracted sample clip starts with several seconds of blank video. The audio starts right away but the video doesn't start for 3-6 seconds. To demonstrate the problem, I've uploaded two video clips and run the above commands on them. I created the first clip in Final Cut Express and encoded it with Handbrake before uploading to the web server: 1a) uploaded clip 1b) converted with first command 1c) extracted with second command, missing first six seconds By comparison, this second clip comes from Apple's website and does not show the problem: 2a) uploaded clip 2b) converted with first command 2c) extracted with second command, no problem Can anyone see what's different about the two source clips? And if so, is there anything I can do in my conversion command so that when the extraction command runs, the clip is set up to avoid the missing video? By the way, I initially had the problem with ffmpeg 0.6.1 installed from yum, but I upgraded to the latest git version and the problem remains.

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• How can I pause console output in rxvt?

  - by Javid Jamae

  I'm running rxvt in Cygwin on a Windows box. This is how I invoke it: rxvt -sr -sl 2500 -sb -geometry 90x30 -tn rxvt -fn "Lucida Console-14" -e /usr/bin/bash --login -i Anyone know how to pause the console output in rxvt? I can use Ctrl-S / Ctrl-Q to pause / un-pause, but this won't work if a script is already running and spewing output to stdout. Highlighting the terminal window with the mouse doesn't seem to work like with other consoles such as the standard Cygwin console, or the Windows command prompt console. Some sort of scroll lock would be nice, but I can't seem to find any way to do this. I know I could just pipe my output to a file, but I want a way to pause the output for something that I didn't expect to explode with console output. Basically I want to scroll back while its running without it constantly moving me to the bottom of the output buffer as it updates more data to stdout. I don't particularly care if the solution given actually pauses the script (like when you highlight the mouse in the Windows Command window), or just scroll locks and let's me scroll while its still running the underlying script, though I'd like to know how to do both if its possible.

• MySQL ODBC + SSL with only the SSL Cipher option?

  - by sdek

  Does anybody know how I can have an SSL encrypted connection over MySQL ODBC without the cert options? So I asked my web host to setup a MySQL+SSL connection so that we can access our website's database via ODBC or MySQL Query Browser (or the likes). I am able to get an encrypted connection with the standard mysql client and MySQL Query Browser, but I can't get the ODBC connection to work. Looking for a little help... The way they set it up is a little different from the way I have read about on the interweb. The host didn't setup a cert, or at least I don't think so - I don't need to specify any cert options in my connection. I just need to specify the ssl cipher. Here is how I connect with the mysql client: mysql -h myhost.com -u myuser --ssl-cipher=3DES -p That works to get an encrypted connection. At least I am pretty sure it works because when I run mysql> \s I get SSL: Cipher in use is EDH-RSA-DES-CBC3-SHA Also, when I put EDH-RSA-DES-CBC3-SHA into the SSL Cipher field of MySQL Query Browser (without specifying any other SSL options) it connects just fine. But then when I try to do the same thing with my MySQL ODBC 3.5.1 and 5.1 I get a generic error. Here is the error from the 5.1 Driver. Connection Failed: [HY000] [MySQL][ODBC 5.1 Driver]SSL connection error

• Synergy Key Mapping

  - by Tauren

  I'm running a Synergy server on Ubuntu and a Synergy+ client on OSX. The server has a standard windows keyboard with shift, ctrl, windows, and alt keys. My MacBookPro has shift, fn, control, alt/option, and command keys. When I press ctrl-c, ctrl-v, etc, the appropriate copy/paste action doesn't happen on the Mac, but it does in Ubuntu. If I'm controlling the mac, and press alt-c, alt-v, then I get the copy/paste action. So I played around with key mapping in synergy.conf and found that the following allows me to do copy/paste with ctrl-c/ctrl-v: section: screens godzilla: mbp.local: ctrl = alt alt = ctrl end Is this all that I need to do? Or are there other mappings that will help as well? The synergy configuration page refers to the following key mappings. What are the equivalent keys for each of these on the Windows keyboard and Mac keyboard? What is a meta or super key? shift = {shift|ctrl|alt|meta|super|none} ctrl = {shift|ctrl|alt|meta|super|none} alt = {shift|ctrl|alt|meta|super|none} meta = {shift|ctrl|alt|meta|super|none} super = {shift|ctrl|alt|meta|super|none} Thanks!

• Require a very simple bash-based webserver for logging XML POST [on hold]

  - by Syffys

  As in title, it's for testing purpose and I need it to be extremely light (1 line to 1 single light file). Here is a XML query sample: XML_QUERY=$(cat <<EOF <?xml version='1.0' encoding='UTF-8'?> <Test></Test> EOF ) curl -H "Content-type: text/xml; charset=utf-8" -H "Soapaction: \"\"" -k -d "${XML_QUERY}" http://localhost:8088 Here are some of the tracks I have found so far even if I wasnt able to adapt them to work as I expect: Netcat minimal webserver: Problem is that my nc does not have the -q option, so the connection is closing before delivering the XML content Netcat Only webserver: Same as above Thanks in advance! EDIT: As it's been asked, I'm running Linux Redhat, even if the distro does not really matter and the OS implied since I'm asking a bash-based solution... Also about my topic being on hold: "Instead, describe your situation and the specific problem you're trying to solve" = I though this was exactly what I was doing, but ok I'll reword: My situation: bash environment (which can also include some standard linux tool: netcat, python or whatever) My specific problem: please see title: Require a very simple bash-based webserver for logging XML in HTTP POST for testing purpose

• TCP Server Memory management: #Connections Vs. #Requests

  - by Andrew

  Given that, there is no theoretical limit to number of concurrent TCP connections a Windows 2008 server can handle. Only thing will happen is, with each connection there will be memory consumption in server. Unfortunately, memory is not unlimited (and I want to utilize only physical memory). For example, lets say we've 2GB server memory. Now there are two extreme cases: Case 1: If we've allocated 64KB buffer for each connection (only to receive incoming request), then 32768 connections can consume all the 2GB of memory. This will not leave any memory to queue/process incoming requests from those connections. Case 2: On the other hand, lets say a single (or very few) connections continuously keeps sending request buffers (for example, video streaming from one connection to other) and server cannot process them within time, those buffers will get piled up in server and eventually will occupy most of the servers memory. And it will not leave any memory for new connection thereafter. This is the real dilemma in server design bugging me badly for last many days. If I can decide on max size of request buffer per connection and max number of requests to allow in queue per connection. Then, based on available server memory, it will then automatically set limit on max number of concurrent connections. How to decide on these limits to achieve best performance and throughput? I am just looking for perfect utilization of server resources. Are there any standard guidelines or empirical data available with someone who can share with me please.

• Server freezes while installing Redhat Enterprise Linux Server 6

  - by eisaacson

  We've tried both the first options Install or upgrade an existing system Install system with basic video driver When trying option #1, it gets to a screen that has a solid cursor about halfway down, then freezes. When trying option #2, it freezes at the point where it says: Waiting for hardware to initialize... Of course, we bought the unsupported version and haven't found anything to help us so far. Here are the specs to the server in the original post: ASUS P8Z68-M Pro LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard with UEFI BIOS RAIDMAX Reiter ATX-305WBP Black Steel / Plastic ATX Mid Tower Computer Case 450W Power Supply Intel Core i7-2600 Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I72600 16GB Ram OCZ Agility 3 SSD 120GB From some of the posts out there could the UEFI Bios or the Sandy Bridge processor be a culprit here? We just tried the DVD on a different computer and it got past that point with ease. It's a standard Dell build compared to our custom machine. Could it be having difficulty recognizing drivers? How do we get past that?

• SeLinux blocking connection to sshd on Ubuntu 9.10

  - by Barton Chittenden

  When I try to log on to my laptop, which runs Ubuntu 9.10, the server rejects my login attempts. Checking /var/log/auth.log, I see the following: Feb 14 12:41:16 tiger-laptop sshd[6798]: error: ssh_selinux_getctxbyname: Failed to get default SELinux security context for tiger I googled for this, and ran across the following: http://www.spinics.net/lists/fedora-.../msg13049.html Here's the part that I think relates to the problem that I'm having: Quote: What's wrong on my system? Why it's not possible to login even if selinux is in permissive mode? Any suggestions? I'd start by trying to figure out why sshd isn't running in sshd_t (it seems to be running in sysadm_t). Paul. selinux mailing list selinux@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mail...stinfo/selinux Yes, sshd is running in sysadm_t: ps axZ | grep sshd system_u:system_r:sysadm_t 3632 ? Ss 0:00 /usr/sbin/sshd -o PidFile=/var/run/sshd.init.pi ls -Z /usr/sbin/sshd system_ubject_r:sshd_exec_t /usr/sbin/sshd Don't know why it's not sshd_t. I didn't modified something. It's a standard installation of sles11 with the default reference policy from tresys. Maybe this code snippet from policy/modules/services/ssh.te is responsible for that: Allow ssh logins as sysadm_r:sysadm_t gen_tunable(ssh_sysadm_login, true) Any ideas? Do you have boolean init_upstart set to on? if not try setting it to on. I do not believe ssh_sysadm_login boolean works currently but i may be mistaken. -- Yeah, setting init_upstart to on did the trick! THANK A LOT! Do you know why this prevents the user from logging in through ssh even if selinux is set to permissive?? Ok, so the million dollar question is "where do I set 'init_upstart=1'"? It's not clear from context which configuration file needs to be edited, and I'm not at all familiar with SELinux configuration.

• Webcam becomes "Unknown Device" after Windows Messenger 2011 is installed

  - by Boris

  I have Sony VAIO VGN-NS290J laptop. I installed Windows 7 Ultimate 64-bit. I was able to find drivers for all hardware without any problems. Recently, I installed Microsoft Windows Live Essentials 2011, i.e. Windows Live Messenger 2011. Ever since that application is running on my computer, my webcam is not recognized by the OS any more. It is listed as the "Unknown Device" and placed in the Universal Serial Bus controllers group in the Device Manager. There don't seem to be any drivers for this webcam. It's a standard Sony Motion Eye web camera and Sony does not offer any drivers for it. There is one application to download that utilizes the camera, but there are no drivers (and the system is showing the same behavior regardless of the presence of the application). It happens from time to time that the webcam becomes recognized by the OS again, after a couple of restarts; but not always. Then it becomes unknown again. I am absolutely positive that this issue is caused by the Windows Live Messenger 2011, because same symptoms caused the same effects before. I wish to be able to continue to use this software, but also to use my webcam. I was wondering if anyone had a similar issue and if there is a way to fix it. Thanks for all the help, I appreciate it. Update: I have discovered a pattern - if the camera goes astray, restarting the machine does not bring it back; but switching the computer off and turning it back on does. Every time! This is getting super complicated :)

• Administrative shares in Windows 7 Pro not visible

  - by Chris Tybur

  My desktop machine has a clean install of Windows 7 Professional. For some reason the standard administrative shares Admin$, C$, D$, etc are not visible, either in Computer Management - Shared Folders - Shares or via net share. I also have a laptop with a clean install of Windows 7 Professional, and I can see the admin shares in both places. As such, I can map to \\laptop\c$ from the desktop, but I can't map to \\desktop\c$ from the laptop. I pretty much took the defaults during the Windows 7 installations. I've tried adding LocalAccountTokenFilterPolicy to the registry on the desktop, but that didn't work. On the desktop I've also disabled UAC, turned off Windows firewall, removed it from a homegroup, made sure file and printer sharing is turned on, but nothing has worked. There is some subtle difference between the two machines that I can't seem to find. I'm logging into both machines using a local account that is in the Administrators group. Both accounts have the same name and password. I really don't want to have to create a new share for the desktop's C drive, especially since C$ is visible and working on the laptop and therefore I should be able to make it work on the desktop. Any idea why the admin shares would work on one machine and not another? Or why LocalAccountTokenFilterPolicy would fail?

• Windows 7 loses correct time zone upon reboot

  I have a standard PC running Windows 7 Ultimate (64-bit). For some reason, it refuses to keep the correct time zone (the BIOS battery is OK) when restarted. Note (1): The Time zone is correct. The "Internet Time" tab also shows "this computer is set to automatically synchronize with 'time.windows.com'. When I click the 'Change settings...' button, the 'Synchronize with an Internet time server' checkbox is checked. Still, upon reboot, the time is skewed by 6 hours... and doesn't correct itself even after waiting hours for this "automatically synchronize" to occur. Note (2): The BIOS time is set to local (i.e. not UTC). When I restart Windows 7 without booting to the other OS installed in dual-boot config (Ubuntu Linux), it seems to correctly remember the time. This may explain immediate time upon reboot, but it doesn't explain why Windows 7 won't automatically 'Synchronize with an Internet time server' even after an hour. Why is this happening and how do I correct this?

• [tcpdump] Proxy delegate refusing connexion ?

  - by simtris

  Hi guys, I'm a little disapointed ! My aim was to build a VERY simple smtp proxy under debian to handle mail from a port (51234) and forward it to the standard 25 port. I compile and install a "delegate" witch can handle easily that. It's working very well like that : delegated SERVER="smtp://anotherSmtpServer:25" -P51234 The strange thing is, it's working on my virtual test machine and on the dedicated server in local but I can't manage to use it trought internet. I test it like that. telnet [mySrv] 51234 Of course, no firewal, no deny host, no ined/xined, the service delegated is listening on the right port ... 2 clues : The port is answering trought internet with nmap as "51234/tcp open tcpwrapped" have a look at the tcpdump following : 22:50:54.864398 IP [myIp].1699 [mySrv].51234: S 2486749330:2486749330(0) win 65535 22:50:54.864449 IP [mySrv].51234 [myIp].1699: S 2486963525:2486963525(0) ack 2486749331 win 5840 22:50:54.948169 IP [myIp].1699 [mySrv].51234: . ack 1 win 64240 22:50:54.965134 IP [mySrv].43554 [myIp].auth: S 2485396968:2485396968(0) win 5840 22:50:55.243128 IP [myIp] [mySrv]: ICMP [myIp] tcp port auth unreachable, length 68 22:50:55.249646 IP [mySrv].51234 [myIp].1699: F 1:1(0) ack 1 win 46 22:50:55.309853 IP [myIp].1699 [mySrv].51234: . ack 2 win 64240 22:50:55.310126 IP [myIp].1699 [mySrv].51234: F 1:1(0) ack 2 win 64240 22:50:55.310137 IP [mySrv].51234 [myIp].1699: . ack 2 win 46 The part "auth" seems suspect to me but didn't ring a bell. I could certaily do with some help. Thx a lot !

• Process to replace motherboard and keep CPU

  - by jolivier

  My motherboard has been diagnosed with the Sandy Bridge issue (http://vip.asus.com/eservice/changeSandybridge_MB.aspx?slanguage=en-us) so I am asked by my reseller to send back my motherboard to have a new one compatible with the previous one. My problem is that I have a not cheap Intel CPU currently on it, with its standard heatsink/fan. I would obviously like to keep it to plug it on the new motherboard. I am quite woried about the thermal paste. I was planning to: Remove the CPU and the HSF together (I think they are sticked to each other). Try to separate the CPU and the HSF (I'm not sure how) Clean both of the surfaces When the new motherboard is here, put the CPU back on it. Have new thermal paste to put again on the CPU, put it on the CPU Add the HSF again Do you see any problem about this process? Recommendations? Is it possible to keep the CPU and the HSF together for the whole process or is it impossible to plug the CPU back on the new motherboard in this case? Thanks in advance for your answers. Olivier

• OS X can connect to Windows machine, but can't access shared folders

  - by Bonnie

  I can create new folders on my Windows XP machine, set them to "shared". On my Mac, I pick Finder → Go → Connect to Server → smb://192.168.1.4 → Connect → Name / Password. It even shows me all the names of the newly created shared-folders on my PC, but when I try to actually connect to any of them I get connection failed, there was an error connecting Any idea on what would cause that? The fact that it successfully gets so far—to actually showing me my PC share-names—must mean I have 99% of this working correctly, i.e. the physical connection, the IP address, the user name, the password, etc. Still, I can't seem to access the folders themselves. I've tried this with my Windows XP firewall on/off, and Norton AntiVirus on/off. Same problem. Everything did work fine, 4 months ago. Were there any odd OS X or Windows updates released recently? I always apply them all. smbclient on the Mac does correctly find the XP machine, my XP user name, and accepts my XP password. I get the following from that smbclient command: Doing spnego session setup (blob length=16) server didn't supply a full spnego negprot Got challenge flags: ... Got NTLMSSP flags: ... Got NTLMSP flags: ... Domain=[XPMACHINE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager] tree connect failed: NT_STATUS_INSUFF_SERVER_RESOURCES I'm not sure why a standard XP box can't "supply a full spnego negprot". Whatever that means. Using XP's RegEdit to change my IRPStackSize from 11... to 13, 15, 20, 22... still gives that "NT_STATUS_INSUFF_SERVER_RESOURCES" error on the Mac.

• How to set up mysql storage for certain rsyslog input matches?

  - by ylluminate

  I'm draining various logs from Heroku to an rsyslog linux (ubuntu) server and am starting to have a little more to bite off than I can chew in terms of working with my log histories. I am needing to be able drill back in time based on more flexible details and more flexible access than what the standard syslog file(s) provide. I'm thinking that logging to mysql may be the correct approach, but how do I set this up such that it pulls only certain log entries into a table based on an identified? For example, I see a long hex string identifying each log entry from a certain Heroku app instance. I assume that I can just pipe those into the mysql socket vs ALL rsyslog input into mysql... Could someone please direct me to a resource that can walk me through the process of setting something like this up or simply provide some details that can help? I have 15+ years of Unix experience so I just need some nudging in the right direction as I've not really done a tremendous amount of work with syslog daemons previously in terms of pooling various servers into one. Additionally, I'd be interested in any log review tools that could make drilling through log arrangements like this more handy for developers.
