• Postfix - suspend domain from which deferred status was received?

  - by Al Bundy

  Is there a possibility to make Postfix stop trying (for a period of time) to send emails to a domain from which it received a deferred response? Currently my Postfix goes through each address in the queue. Please see the below example. At 09:48:32 the status=deferred appears. After this Postfix should stop trying to send stuff to the yahoo.com domain.

• Why does my MacBook Pro have long ping times over Wi-Fi?

  - by randynov

  I have been having problems connecting with my Wi-Fi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10 seconds before slowly coming back down. You can see the trend below. I'm on a MacBook Pro and have done the normal stuff (reset the PRAM and SMC, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 and 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation?

• Why does this mod_rewrite rule 'not-match'? (big rewrite log included)

  - by Christopher

  I've got a scenario involving two domains: WordPress site hosted on domain1.com domain2.co.uk, simply redirecting users to domain1 via mod_rewrite This rule applies irrespective of whether www. is specified or not. (It's eventually removed from the URL, I'm a no-WWW fan.) There's nothing on domain2.co.uk at all except for an .htaccess with some mod_rewrite rules. However, I want to be able to allow users to be redirected to the correct article URI even if they specify the "wrong" URL (i.e., a 301 redirect preserving the stuff after the first forward slash). I'm currently achieving this with this ruleset: RewriteCond %{HTTP_HOST} ^((www\.)?[^\.]+)\.domain2\.co\.uk [NC,OR] RewriteCond %{HTTP_HOST} ^domain2\.co\.uk [NC] RewriteRule ^(.*)$ http://domain1.com/$1 [R=301,L] This works but is uglier than I want it to be. I'm not a mod_rewrite zen master, but from what I can tell the top rule should match irrespective of whether www. is specified... But it doesn't. In order to catch www-less requests, I need the second RewriteCond. From the rewrite log, with just the first RewriteCond: [domain2.co.uk/sid#e200498][rid#e670168/initial] (3) [perdir /home/devnull/domains/domain2.co.uk/public_html/] strip per-dir prefix:

• Windows 7 Machine Makes Router Drop -All- Wireless Connections

  - by Hammer Bro.

  Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• Cisco PIX 8.0.4, static address mapping not working?

  - by Bill

  upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

• Why does my macbook pro have long ping times over wifi?

  - by randynov

  I have been having problems connecting with my wifi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10s before slowly coming back down. You can see the trend below. I'm on a macbook pro and have done the normal stuff (reset the pram and smc, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 & 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation? TIA!

• Mac OS X Server Open Directory does not push Software Update settings to clients

  - by joxl

  I have an Xserve G5 running Mac OS X Server 10.5.8 configured as an Open Directory master. I have also enabled and configured Software Update service on the machine. The SUS is configured to serve Tiger, Leopard and Snow Leopard clients (see http://discussions.apple.com/message.jspa?messageID=10297359#10297359) The clients bound to the OD are a variety of Mac's running OS X 10.4, 10.5 or 10.6. In Workgroup Manager, I have created 3 machine groups for each client OS. Each group is configured with a custom SUS URL, and the managed client computers are members accordingly (see http://discussions.apple.com/thread.jspa?messageID=10493154#10493154) My problem is that the server pushes the SUS settings to some of the client machines, but not all. When I first configured all this stuff on the server (a few weeks ago) I was closely monitoring a few of the client machines to confirm that they received the custom settings. I noticed that some of the clients (10.4/5/6 alike) seemed to get the settings immediately, others didn't show the new settings until after a reboot. As I said, results are mixed across OS's, but some clients will not "sync" at all. My immediate thought was to unbind/rebind the problematic machines. I did this on several client computers with no success. For example, today I was working on one of the Tiger clients. I noticed it was not pointed at my local SUS, so I checked the OD binding; it was fine. Just to be sure I unbound the machine. Next, I checked WM and confirmed the computer record was gone. I noticed the machine group still had a residual (broken?) member from the unbound client; I manually removed this. Finally, I re-bound the client to OD and re-added the machine to it's correct group in WM. Unfortunately, the client still pings apple's SUS for updates. Just to play it safe I rebooted the client, but to no avail, it will not see my local SUS. To confirm that there is nothing wrong with the server, or the client's connection to it, forcefully pointed the machine at my SUS: sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL "$LOCAL_SUS_URL" and the machine successfully updated off my local server. Great, successful updates, but problem not solved. I've done exhaustive reading on discussions.apple.com (not saying I read everything, I'm just saying I have read a lot) without a good answer. The discouraging thing is that a lot of OD problems I've read about only result in the sysadmin completely reinstalling the server, or OD, or some other similarly heavy-handed operation. At this point, I am not willing to go that route. I still have hope that I can find the reason for this flaky behavior. If anyone can point me in a helpful direction it would be much appreciated. EDIT: Indeed, some files are being pushed to the client: # from client machine: $ sudo find /Library -type f -name com.apple.SoftwareUpdate.plist /Library/Managed Preferences/com.apple.SoftwareUpdate.plist /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist /Library/Preferences/com.apple.SoftwareUpdate.plist A few weeks ago, prior to my (previously mentioned) modifications, the SUS was still running "stock". Which meant it could not serve SL (10.6) machines. At that time, the Software Update settings were setup in WM under User Groups. This didn't make any sense because some users work on multiple machines with different OS's. Before creating Machine Groups in WM, I deleted all the SU settings from the User Group Preferences. This just makes the whole thing more confusing, because when I see a file here: /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist I assume it's still remaining from the "old" settings, because I wouldn't think a Machine Setting belongs there. Despite all the com.apple.SoftwareUpdate.plist hanging around under the Managed Preferences, why does the client machine still call home to Apple and not my SUS? # on client machine: $ date Tue Jan 25 17:01:46 EST 2011 $ softwareupdate --list Software Update Tool Copyright 2002-2005 Apple No new software available. switch terminals... # on server: $ tail -n1 /var/log/swupd/swupd_access_log 10.x.x.x - - [25/Jan/2011:15:54:29 -0500] XXXX POST "/cgi-bin/SoftwareUpdateServerStats" 200 13 ... Notice the date of the client softwareupdate and the latest access to the SUS server; the server never heard a peep from that client.

• What is causing the unusual high load average and IOwait?

  - by James

  I noticed on Tuesday night of last week, the load average went up sharply and it seemed abnormal since the traffic is small. Usually, the numbers usually average around .40 or lower and my server stuff (mysql, php and apache) are optimized. I noticed that the IOWait is unusually high even though the processes is barely using any CPU. top - 01:44:39 up 1 day, 21:13, 1 user, load average: 1.41, 1.09, 0.86 Tasks: 60 total, 1 running, 59 sleeping, 0 stopped, 0 zombie Cpu0 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu2 : 0.0%us, 0.3%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu4 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu5 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu6 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu7 : 0.0%us, 0.0%sy, 0.0%ni, 91.5%id, 8.5%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1048576k total, 331944k used, 716632k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1 root 15 0 2468 1376 1140 S 0 0.1 0:00.92 init 1656 root 15 0 13652 5212 664 S 0 0.5 0:00.00 apache2 9323 root 18 0 13652 5212 664 S 0 0.5 0:00.00 apache2 10079 root 18 0 3972 1248 972 S 0 0.1 0:00.00 su 10080 root 15 0 4612 1956 1448 S 0 0.2 0:00.01 bash 11298 root 15 0 13652 5212 664 S 0 0.5 0:00.00 apache2 11778 chikorit 15 0 2344 1092 884 S 0 0.1 0:00.05 top 15384 root 18 0 17544 13m 1568 S 0 1.3 0:02.28 miniserv.pl 15585 root 15 0 8280 2736 2168 S 0 0.3 0:00.02 sshd 15608 chikorit 15 0 8280 1436 860 S 0 0.1 0:00.02 sshd Here is the VMStat procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 0 0 768644 0 0 0 0 14 23 0 10 1 0 99 0 IOStat - Nothing unusal Total DISK READ: 67.13 K/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 19496 be/4 chikorit 11.85 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 19501 be/4 mysql 3.95 K/s 0.00 B/s 0.00 % 0.00 % mysqld 19568 be/4 chikorit 11.85 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 19569 be/4 chikorit 11.85 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 19570 be/4 chikorit 11.85 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 19571 be/4 chikorit 7.90 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 19573 be/4 chikorit 7.90 K/s 0.00 B/s 0.00 % 0.00 % apache2 -k start 1 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % init 11778 be/4 chikorit 0.00 B/s 0.00 B/s 0.00 % 0.00 % top 19470 be/4 mysql 0.00 B/s 0.00 B/s 0.00 % 0.00 % mysqld Load Average Chart - http://i.stack.imgur.com/kYsD0.png I want to be sure if this is not a MySQL problem before making sure.

• Cyrus on CentOS with sasl / pam / ldap

  - by Oscar

  SASL/PAM/LDAP is driving me crazy... that's what I read a lot when googling for problems in this area, and what I experience myself :-S I'm trying to get Cyrus imap working for virtual hosting on CentOS with this authorisation backend and really don't know what's happening. In saslauthd I configured the LDAP search filter to use, but it looks like pam completely ignores it. Here's what I do for testing (done more tests but all with similar results): [root@testserv ~]# imtest -u [email protected] -a [email protected] WARNING: no hostname supplied, assuming localhost S: * OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID STARTTLS] testserv.

The weird thing is, I do get an error when I rename or remove /etc/saslauthd.conf, but when the file exists it seems happily ignored... The filter in slapd.log seems to be taken from /etc/ldap.conf. Apart from some timers, that only contains: host 127.0.0.1 base o=mydomain,c=com pam_login_attribute mail Outcommenting the pam_login_attribute results in this filter in slapd.log: filter="([email protected])" Pam-imap looks like this: [root@testserv ~]# cat /etc/pam.d/imap auth required pam_ldap.so debug account required pam_ldap.so debug #auth sufficient pam_unix.so likeauth nullok #auth sufficient pam_ldap.so use_first_pass #auth required pam_deny.so #account sufficient pam_unix.so #account sufficient pam_ldap.so The outcommented stuff is because I don't have the cyrus admin user in Ldap; that's a Linux user. That works fine when uncommented, but I still need to play around with that a little and first I wanna get imap working.

• Strategy for using snapshots to back up Ubuntu Linux server?

  - by MountainX

  I need some backup advice for my home file server. Here are the mount points, volume groups, logical volumes and used/total space of all the volumes on my Ubuntu 8.10 home file server. / vgA/lvRoot [7.5G/50G] /tmp vgB/lvTmp [195M/30G] /var vgB/lvVar [780M/30G] swap vgB/lvSwap [16.00 GB] /media1 vgC/lvMedia1 [400G/975G] /media2 vgC/lvMedia2 [75G/295G] /boot partition (no volume group) [95M/200M] /video partition (no volume group) [450G/950G] /backups vgD/lvBackupTarget [800G/925G] /home vgE/lvHome [85G/200G] I have just added a 2.0 TB external USB drive that I would like to use to backup everything. (It will be a close fit to get it all on one 2.0 TB drive. I actually have a 2nd external USB drive if needed.) I'd like to backup "/", var, /media1, media2 and /home. I'll deal with /boot and /video separately since they are not logical volumes. For all the logical volumes I'm anticipating taking snapshots and then copying those snapshots to the 2.0 TB external USB drive. I have never done a task like that before. If I do that, I could use the tutorial I found here: http://www.howtoforge.com/linux_lvm_snapshots My questions are: What is the best overall strategy? Is it LVM snapshots, as I'm assuming? How should I prepare, subdivide and mount the 2.0 TB external USB drive? 2.a. Should I create one or more regular partitions or should I create a physical volume with one or more logical volumes? 2.b. Would it be advisable to extactly mirror the source pv/lv layout on the external drive, and if so, is this a good strategy? What's the best way to get the snapshots onto the external drive? dd? Even though this is a strategy question, feedback with actual commands is appreciated. I need step-by-step cookbook-style help because I don't do much server admin work. (Background: This is a home file server that I have rarely had to touch in about 2 years. It has done its job without much intervention. The really old PC that I used to back everything up recently failed, so I'm replacing that with the external USB drive(s) and I'd like to upgrade my backup strategy at the same time. Previously, I just copied stuff from /backups over to the other computer and that would not have made things very easy in a real restore situation. The /backups mount point contains backup copies of "most" of the important data on a file by file basis, but it does not contain copies of /boot, etc. BTW, the actual internal HDD that holds /backups is separate from the other storage devices.) EDIT: I'll propose a strategy... The idea came from a comment here: LVM mirroring VS RAID1 "LVM mirrors are for replication of a logical volume to a different physical volume. It's essentially meant to "move the data to a different disk". The mirror is then broken..." That would fit my requirements well. Here is an ideal situation: establish the LV mirror on the external drive break the link with the mirror create a (persistent) snapshot on the mirror after a week, resync the mirror with the original source and update the mirror break the link and create another snapshot on the mirror. Obviously, the mirror will be like a weekly full backup. And the snapshots on the mirror will represent earlier points in time. If this would work and if it would be time efficient, it would give a nice full & differential type backup on the external drive based on LVM. I have not heard of a strategy like this before. Will it work? Could it be scripted? Thoughts? EDIT 2: Creating Portable DiskSafes With LoopbackFS And LVM Snapshots This article seems intriguing: http://www.howtoforge.com/creating-portable-disksafes-with-loopbackfs-and-lvm-snapshots Unfortunately, I don't understand exactly how to map those ideas to the strategy I'm proposing above. I'm going to ask this last bit as a separate question. I will leave my original question in place because I still desire feedback on the overall best strategy. At this moment I'm assuming it is LVM mirroring in the style of "Creating Portable DiskSafes with LVM Snapshots" but that might be wrong.

• Can't connect to STunnel when it's running as a service

  - by John Francis

  I've got STunnel configured to proxy non SSL POP3 requests to GMail on port 111. This is working fine when STunnel is running as a desktop app, but when I run the STunnel service, I can't connect to port 111 on the machine (using Outlook Express for example). The Stunnel log file shows the port binding is succeeding, but it never sees a connection. There's something preventing the connection to that port when STunnel is running as a service? Here's stunnel.conf cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ;

• Can't connect to STunnel when it's running as a service

  - by John Francis

  I've got STunnel configured to proxy non SSL POP3 requests to GMail on port 111. This is working fine when STunnel is running as a desktop app, but when I run the STunnel service, I can't connect to port 111 on the machine (using Outlook Express for example). The Stunnel log file shows the port binding is succeeding, but it never sees a connection. There's something preventing the connection to that port when STunnel is running as a service? Here's stunnel.conf cert = stunnel.pem ; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log ;

• Windows 7 Machine Makes Router Drop -All- Wireless Connections [closed]

  - by Hammer Bro.

  Note: I accidentally originally posted this question over at SuperUser, and I still think the issue is caused by some low-level networking practice of Windows 7, but I think the expertise here would be more apt to figuring it out. Apologies for the cross-post. Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• mdadm raid5 recover double disk failure - with a twist (drive order)

  - by Peter Bos

  Let me acknowledge first off that I have made mistakes, and that I have a backup for most but not all of the data on this RAID. I still have hope of recovering the rest of the data. I don't have the kind of money to take the drives to a recovery expert company. Mistake #0, not having a 100% backup. I know. I have a mdadm RAID5 system of 4x3TB. Drives /dev/sd[b-e], all with one partition /dev/sd[b-e]1. I'm aware that RAID5 on very large drives is risky, yet I did it anyway. Recent events The RAID become degraded after a two drive failure. One drive [/dev/sdc] is really gone, the other [/dev/sde] came back up after a power cycle, but was not automatically re-added to the RAID. So I was left with a 4 device RAID with only 2 active drives [/dev/sdb and /dev/sdd]. Mistake #1, not using dd copies of the drives for restoring the RAID. I did not have the drives or the time. Mistake #2, not making a backup of the superblock and mdadm -E of the remaining drives. Recovery attempt I reassembled the RAID in degraded mode with mdadm --assemble --force /dev/md0, using /dev/sd[bde]1. I could then access my data. I replaced /dev/sdc with a spare; empty; identical drive. I removed the old /dev/sdc1 from the RAID mdadm --fail /dev/md0 /dev/sdc1 Mistake #3, not doing this before replacing the drive I then partitioned the new /dev/sdc and added it to the RAID. mdadm --add /dev/md0 /dev/sdc1 It then began to restore the RAID. ETA 300 mins. I followed the process via /proc/mdstat to 2% and then went to do other stuff. Checking the result Several hours (but less then 300 mins) later, I checked the process. It had stopped due to a read error on /dev/sde1. Here is where the trouble really starts I then removed /dev/sde1 from the RAID and re-added it. I can't remember why I did this; it was late. mdadm --manage /dev/md0 --remove /dev/sde1 mdadm --manage /dev/md0 --add /dev/sde1 However, /dev/sde1 was now marked as spare. So I decided to recreate the whole array using --assume-clean using what I thought was the right order, and with /dev/sdc1 missing. mdadm --create /dev/md0 --assume-clean -l5 -n4 /dev/sdb1 missing /dev/sdd1 /dev/sde1 That worked, but the filesystem was not recognized while trying to mount. (It should have been EXT4). Device order I then checked a recent backup I had of /proc/mdstat, and I found the drive order. md0 : active raid5 sdb1[0] sde1[4] sdd1[2] sdc1[1] 8790402048 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/4] [UUUU] I then remembered this RAID had suffered a drive loss about a year ago, and recovered from it by replacing the faulty drive with a spare one. That may have scrambled the device order a bit...so there was no drive [3] but only [0],[1],[2], and [4]. I tried to find the drive order with the Permute_array script: https://raid.wiki.kernel.org/index.php/Permute_array.pl but that did not find the right order. Questions I now have two main questions: I screwed up all the superblocks on the drives, but only gave: mdadm --create --assume-clean commands (so I should not have overwritten the data itself on /dev/sd[bde]1. Am I right that in theory the RAID can be restored [assuming for a moment that /dev/sde1 is ok] if I just find the right device order? Is it important that /dev/sde1 be given the device number [4] in the RAID? When I create it with mdadm --create /dev/md0 --assume-clean -l5 -n4 \ /dev/sdb1 missing /dev/sdd1 /dev/sde1 it is assigned the number [3]. I wonder if that is relevant to the calculation of the parity blocks. If it turns out to be important, how can I recreate the array with /dev/sdb1[0] missing[1] /dev/sdd1[2] /dev/sde1[4]? If I could get that to work I could start it in degraded mode and add the new drive /dev/sdc1 and let it resync again. It's OK if you would like to point out to me that this may not have been the best course of action, but you'll find that I realized this. It would be great if anyone has any suggestions.

• Performance required to improve Windows Experience Index?

  - by Ian Boyd

  Is there a guide on the metrics required to obtain a certain Windows Experience Index? A Microsoft guy said in January 2009: On the matter of transparency, it is indeed our plan to disclose in great detail how the scores are calculated, what the tests attempt to measure, why, and how they map to realistic scenarios and usage patterns. Has that amount of transparency happened? Is there a technet article somewhere? If my score was limited by my Memory subscore of 5.9. A nieve person would suggest: Buy a faster RAM Which is wrong of course. From the Windows help: If your computer has a 64-bit central processing unit (CPU) and 4 gigabytes (GB) or less random access memory (RAM), then the Memory (RAM) subscore for your computer will have a maximum of 5.9. You can buy the fastest, overclocked, liquid-cooled, DDR5 RAM on the planet; you'll still have a maximum Memory subscore of 5.9. So in general the knee-jerk advice "buy better stuff" is not helpful. What i am looking for is attributes required to achieve a certain score, or move beyond a current limitation. The information i've been able to compile so far, chiefly from 3 Windows blog entries, and an article: Memory subscore Score Conditions ======= ================================ 1.0 < 256 MB 2.0 < 500 MB 2.9 <= 512 MB 3.5 < 704 MB 3.9 < 944 MB 4.5 <= 1.5 GB 5.9 < 4.0GB-64MB on a 64-bit OS Windows Vista highest score 7.9 Windows 7 highest score Graphics Subscore Score Conditions ======= ====================== 1.0 doesn't support DX9 1.9 doesn't support WDDM 4.9 does not support Pixel Shader 3.0 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 7.9 Windows 7 highest score Gaming graphics subscore Score Result ======= ============================= 1.0 doesn't support D3D 2.0 supports D3D9, DX9 and WDDM 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 6.0-6.9 good framerates (e.g. 40-50fps) at normal resoltuions (e.g. 1280x1024) 7.0-7.9 even higher framerates at even higher resolutions 7.9 Windows 7 highest score Processor subscore Score Conditions ======= ========================================================================== 5.9 Windows Vista highest score 6.0-6.9 many quad core processors will be able to score in the high 6 low 7 ranges 7.0+ many quad core processors will be able to score in the high 6 low 7 ranges 7.9 8-core systems will be able to approach 8.9 Windows 7 highest score Primary hard disk subscore (note) Score Conditions ======= ======================================== 1.9 Limit for pathological drives that stop responding when pending writes 2.0 Limit for pathological drives that stop responding when pending writes 2.9 Limit for pathological drives that stop responding when pending writes 3.0 Limit for pathological drives that stop responding when pending writes 5.9 highest you're likely to see without SSD Windows Vista highest score 7.9 Windows 7 highest score Bonus Chatter You can find your WEI detailed test results in: C:\Windows\Performance\WinSAT\DataStore e.g. 2011-11-06 01.00.19.482 Disk.Assessment (Recent).WinSAT.xml <WinSAT> <WinSPR> <DiskScore>5.9</DiskScore> </WinSPR> <Metrics> <DiskMetrics> <AvgThroughput units="MB/s" score="6.4" ioSize="65536" kind="Sequential Read">89.95188</AvgThroughput> <AvgThroughput units="MB/s" score="4.0" ioSize="16384" kind="Random Read">1.58000</AvgThroughput> <Responsiveness Reason="UnableToAssess" Kind="Cap">TRUE</Responsiveness> </DiskMetrics> </Metrics> </WinSAT> Pre-emptive snarky comment: "WEI is useless, it has no relation to reality" Fine, how do i increase my hard-drive's random I/O throughput?

• OSX Server 3, Mac clients binding to OD and Profile Manager failing

  - by dbf

  I've made a setup containing a Mac Mini with OSX Server 3 (Mavericks 10.9.2) using Open Directory and Profile Manager (Mail, etc all set up and working). Now the thing is, internally on the local network, everything works great. Clients can bind to the OD and the users are able to login. I can install trust and settings profiles (either custom or group profiles) and all services in the profiles mentioned are being configured correctly. I can log in and out, hump around and do it a 100 times on different macs with different users, it works. My goal is to make this service publicly. The domain is with a FQDN which I own, for simplicity let's say server.domain.com. Now the only way for me to bind the clients to the OD is using LDAP mapping RCF2307 (without SSL) and a DN suffix of dc=server,dc=domain,dc=com using the Directory Utility. The options from server, or open directory will throw several errors like Connection failed to node '/LDAPv3/server.domain.com (2100). First of all I don't really understand the problem why clients can't bind to the OD like it does locally, with and without SSL (all ports are open, literally all ports are open, not just 389,636 and 1640, wasn't sure if I was missing any). When the clients are using LDAP mapping RFC2307 to bind (without SSL only), clients are able to authenticate, login and even load the Trust profile. But every Settings profile will fail with a Debug Message: Unable to find GUID in user record OD or fail to install saying missing user identification. Is there any way to get this to work without RFC2307? Because there is quite some stuff missing when using RFC2307 and not pull the mapping from the server or use open directory. Is this setup even possible? Or should I use VPN to authenticate with the OD? The network setup is a Modem/Router (DHCP off) with WAN NATted to an Airport Extreme (Using DHCP+NAT). The AE does notify with a double NAT message but I haven't had any problems with it on any other service. So WAN - 192.168.2.220 (static), AE - 10.0.1.* (dhcp) Output of DIG from the outside using dig server.domain.com ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;server.domain.com.

Only have OSX. -- double NAT issue, plugged in the server directly on the Modem/Router with a static IP and issue remains. Guess that rules out the double NAT thing. -- changeip -checkhostname comes with There is nothing to change, e.g. success. Primary address = 10.0.1.11 Current HostName = server.domain.com DNS HostName = server.domain.com For now, I've made a workaround by using an admin account that forces a permanent VPN connection on boot. That means before it comes to the login, a connection is already made or underway. I will continue this post when I have more time, also locating all the necessary .log files of each application involved. I have some suspicions but have to debug a bit more when I have more time on my hands .. Unless, of course, I get sidetracked with having a life. Which is arguably not very likely. krypted.com

• Software: Launching League of Legends spectator mode from Command Line (Mac)

  - by Alex Popov

  Background: tl;dr at the end League of Legends has a spectator mode, in which you can watch someone else's game (essentially a replay) with a 3 minute delay. Popular LoL website OP.GG has figured out a clever way of hosting these spectator games on their own servers, thereby making them replayable, as opposed to only being available while the game is on (as Riot does it). If you request a replay from OP.GG, it sends a batch file which looks for where the League is situated and then the magic happens: @start "" "League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator fspectate.op.gg:4081 tjJbtRLQ/HMV7HuAxWV0XsXoRB4OmFBr 1391881421 NA1" This works fine on Windows. I'm trying to get it to work on Mac (which has an official client). First I tried running the same command by hand, (split for convenience) /Applications/ ... /LeagueOfLegends.app/ ... /LeagueofLegends 8393 LoLLauncher \ /Applications/ ... /LolClient spectator fspectate.op.gg:4081 tjJbtRLQ/HMV7HuAxWV0XsXoRB4OmFBr 1391881421 NA1 Running this, however, just starts the LoLLauncher, which closes all the active League processes. The exactly same thing happens if I just call /Applications/ ... /LeagueOfLegends.app/ ... /LeagueofLegends Next I tried seeing what actually happens when Spectator mode is initiated so I ran $ ps -axf | grep -i lol which showed UID PID PPID C STIME TTY TIME CMD 503 3085 1 0 Wed02pm ?? 0:00.00 (LolClient) 503 24607 1 0 9:19am ?? 0:00.98 /Applications/League of Legends.app/Contents/LOL/RADS/system/UserKernel.app/Contents/MacOS/UserKernel updateandrun lol_launcher LoLLauncher.app 503 24610 24607 0 9:19am ?? 1:08.76 /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_launcher/releases/0.0.0.122/deploy/LoLLauncher.app/Contents/MacOS/LoLLauncher 503 24611 24610 0 9:19am ?? 1:23.02 /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_air_client/releases/0.0.0.127/deploy/bin/LolClient -runtime .\ -nodebug META-INF\AIR\application.xml .\ -- 8393 503 24927 24610 0 9:44am ?? 0:03.37 /Applications/League of Legends.app/Contents/LoL/RADS/solutions/lol_game_client_sln/releases/0.0.0.117/deploy/LeagueOfLegends.app/Contents/MacOS/LeagueofLegends 8394 LoLLauncher /Applications/League of Legends.app/Contents/LoL/RADS/projects/lol_air_client/releases/0.0.0.127/deploy/bin/LolClient spectator 216.133.234.17:8088 Yn1oMX/n3LpXNebibzUa1i3Z+s2HV0ul 1400781241 NA1 Of Interest: there is (LolClient) which I cannot kill by it's PID. UserKernel updateandrun lol_launcher LoLLauncher.app is launched first. LoLLauncher is launched by the UserKernel (as we can see from the PPID) The very long command (PID: 24927) is how Spectator mode is launched, and is also launched by UserKernel. Spectator mode is launched in exactly the same way that the OP.GG .bat wanted to, with the only difference that Spectator mode connects to Riot instead of OP.GG's spectate server. I tried attaching GDB to the LolClient, but I couldn't get anything meaningful from it since it's an Adobe AIR application (and I've never used GDB with code other than mine own). Next I ran dtruss -a -b 100m -f -p $PID on everything I could think of: the LolClient, the LolLauncher and the UserKernel and skimmed the half a million lines produced. I found stuff like the GET request used to get the information of the game to spectate, but I could not see any launch of the equivalent of League of Legends.exe with spectator options. Finally, I ran lsof | grep -i lol to see if anything else was opened in the process, but didn't find anything that seemed appropriate. Open were UserKernel, LolLauncher, LolClient, Adobe AIR, LeagueofLegends and then Bugsplat, all of which are expected. None of this seemed especially relevant to figuring out how LeagueofLegends was opened into spectator mode. It obviously can be done, since Spectator mode is accessible from within the client. It seems likely that it can be done from the CLI, since Windows can do it and the clients are supposed to equals. Unless I'm missing something in the difference between how UNIX and Windows handle CLI application launches. My question is if there are any other things I can try to figure out how to launch Spectator mode myself. tl;dr: Trying to get into spectator mode from the CLI. It's possible on Windows (see first code block) but it just restarts League on Mac. What else can I try to find what call is made, and how to reproduce it? PS: Please let me know how I can improve this question or its formatting, I'd love to use StackOverflow/SuperUser, but as the guys said on the podcast this week (Ep. 59) it's very intimidating. Sorry for posting this on StackOverflow the first time :(

• In Exim, is RBL spam rejected prior to being scanned by SpamAssassin?

  - by user955664

  I've recently been battling spam issues on our mail server. One account in particular was getting hammered with incoming spam. SpamAssassin's memory use is one of our concerns. What I've done is enable RBLs in Exim. I now see many rejection notices in the Exim log based on the various RBLs, which is good. However, when I run Eximstats, the numbers seem to be the same as they were prior to the enabling of the RBLs. I am assuming because the email is still logged in some way prior to the rejection. Is that what's happening, or am I missing something else? Does anyone know if these emails are rejected prior to being processed by SpamAssassin? Or does anyone know how I'd be able to find out? Is there a standard way to generate SpamAssassin stats, similar to Eximstats, so that I could compare the numbers? Thank you for your time and any advice. Edit: Here is the ACL section of my Exim configuration file ###################################################################### # ACLs # ###################################################################### begin acl # ACL that is used after the RCPT command check_recipient: # to block certain wellknown exploits, Deny for local domains if # local parts begin with a dot or contain @ % ! / | deny domains = +local_domains local_parts = ^[.] : ^.*[@%!/|] # to restrict port 587 to authenticated users only # see also daemon_smtp_ports above accept hosts = +auth_relay_hosts condition = ${if eq {$interface_port}{587} {yes}{no}} endpass message = relay not permitted, authentication required authenticated = * # allow local users to send outgoing messages using slashes # and vertical bars in their local parts. # Block outgoing local parts that begin with a dot, slash, or vertical # bar but allows them within the local part. # The sequence \..\ is barred.

• Managing BES Software Configurations

  - by DaveJohnston

  Hi, I am having problems with OTA deployment of a bespoke application that we have written. I have read loads of threads elsewhere and I have got mixed help, but for my particular case none of it has really helped. So I thought I would explain my exact situation and try and get some help here. I am running BES version 4.1.5 (Bundle 79) for Microsoft Exchange. The application we have written is split into 5 modules, which we control, and another 4 modules which are 3rd party libraries that we require. So for our modules the version numbers are regularly changing but for the others they are pretty much always going to remain the same. We have an alx file set up that identifies all of the files required and in fact I am able to create a software configuration and deploy the application with no problems. What I am trying to do however is maintain multiple versions of our application on the BES and be able to select which version I want to deploy to each user. I have tried this a number of ways (as I said I have read lots of other threads with solutions to this problem) but each seems to come with its own problem. First of all I tried just creating different configurations for each version of the application, but because they each had the same application ID the BES informed me that I couldn't do this. I read somewhere that the solution was to create a second shared folder (e.g. \Program Files\Common Files\RIM) and add the apploader stuff and the new version of the app to this folder. I could then create a second software configuration that would have the same application ID. The result of this seemed promising to start with. When I changed the config that was assigned to a user the new version was pushed out fine. But afterwards the BES reported that the device state was invalid, which meant I couldn't push anything else until I reactivated the device. I guess this is because the first config was never set to disallowed so the old version wasn't removed and the device essentially reported that it had multiple versions of the same application installed. The next suggestion I got was to change the application ID for each version, e.g. to include the version number. This meant that each version of the application could be included in a single configuration and I could set one to disallowed and the other to required. Initially this worked and the first version was deployed. But when I switched (i.e. the old version became disallowed and the new version required) the BES reported upgrade required and removed the old version. The device restarts and the old version is gone but the new version is not pushed out. I checked the BES and it still said Upgrade Required. I checked the log files and found: [40000] (11/12 09:50:27.397):{0xEB8} {[email protected], PIN=1234, UserId=2}SCS::PollDBQueueNewRequests - Queuing POLL_FOR_MISSING_APPS request [40000] (11/12 09:50:28.241):{0xE9C} RequestHandler::PollForMissingApps: Starting Poll For Missing Apps.

(You will notice I have removed actual names and email addresses etc for privacy reasons. But one question: where does the name of the module group come from? In my case it is close to the application ID but doesn't include the version number that I added at the end in order to get it to work. Is that information embedded in a COD file or something??) So it is reporting a duplicate module group on the device? What does this mean? I checked the device properties (as reported on the BES) and it confirms that the modules with the old version numbers are still present on the device. So the application has been removed but not the modules?? I checked the device and the modules are gone, so it is just the BES reporting that they are still there?? I checked the database and it has the modules in questions in the SyncDeviceMgmt table. If I delete these from the DB the BES changes to report Install Required, and low and behold the new version of the app is pushed out. So at the end of all that, my question is: does anyone have any other suggestions of how to handle upgrading our bespoke application OTA from the BES? Or can anyone point out something I am doing wrong in what I described above that might solve the problems I am having? I guess the question is why does the database maintain that the modules are on the device after they are removed? Thanks for any help you can provide.

• Cisco PIX 515 doesn't seem to be passing traffic through according to static route

  - by Liquidkristal

  Ok, so I am having a spot of bother with a Cisco PIX515, I have posted the current running config below, now I am no cisco expert by any means although I can do basic stuff with them, now I am having trouble with traffic sent from the outside to address: 10.75.32.25 it just doesn't appear to be going anywhere. Now this firewall is deep inside a private network, with an upstream firewall that we don't manage. I have spoken to the people that look after that firewall and they say they they have traffic routing to 10.75.32.21 and 10.75.32.25 and thats it (although there is a website that runs from the server 172.16.102.5 which (if my understanding is correct) gets traffic via 10.75.32.23. Any ideas would be greatly appreciated as to me it should all just work, but its not (obviously if the config is all correct then there could be a problem with the web server that we are trying to access on 10.75.32.25, although the users say that they can get to it internally (172.16.102.8) which is even more confusing) PIX Version 6.3(3) interface ethernet0 auto interface ethernet1 auto

• My D-Link's Ethernet bridge downlink just got 10-30x slower?

  - by Jay Levitt

  TL;DR: I unplugged my network to move my desk, and now downloading via my DIR-655's Ethernet LAN bridge is 10-30x slower than the Ethernet switch it's plugged into. Background My network is SMC cable modem <-> Cisco firewall <-> Netgear switch <-> D-Link WiFi† | | | | SMC8014 ASA-5505 GS608v2 gigE DIR-655 rev A3 gigE †The DIR-655 is used as an access point, not a router (although what D-Link calls an access point, I'd call a bridge). The "WAN" port is unused; the Netgear connects to the built-in 4-port Ethernet LAN switch, inside the built- in router/firewall. Endpoints: MacBook Pro 17" mid-2010 iPhone 4S Fedora 12 Linux server running reasonably fast dual-Athlon X2, VelociRaptors, etc. All cables are <10 feet, mostly CAT-5e, some CAT-6, all premade. All WiFi endpoints are within three feet of the D-Link. Yesterday I unplugged and rearranged stuff, and now connecting via the D-Link - even through the wired switch, right next to the incoming network cable - is 30x slower than connecting directly to the Netgear switch, on both my MacBook and iPhone. How I'm measuring "slower" I'm mostly using http://speedtest.net, which of course only really measures broadband speeds. I've also installed http://www.speedtest.net/mini.php on my local server, but can't test the iPhone with that. Results Speedtest.net, closest server over Comcast business-class: CONFIG | PING (ms) | DOWN (Mbps) | UP (Mbps) Mac <-> Ethernet <-> Netgear | 9 | 31.6 | 6.8 Mac <-> Ethernet <-> D-Link | 8 | 4.1 | 6.0 Mac <-> WiFi <-> D-Link | 9 | 1.4 | 2.9 iPhone <-> WiFi <-> D-Link | 67 | 0.4 | 1.6 Speedtest Mini on Linux PC: CONFIG | DOWN (Mbps) | UP (Mbps) Mac <-> Ethernet <-> NetGear | 97.2 | 76.9 Mac <-> Ethernet <-> D-Link | 8.2 | 24.2 Mac <-> WiFi <-> D-Link | 1.0 | 8.6 Slow typing in SSH: Mac <-> Ethernet <-> Netgear <-> Linux PC: smooth Mac <-> Ethernet <-> D-Link <-> Linux PC: choppy Note that D-Link upload speeds are normal on broadband, slower locally (but I'd believe that's a D-Link limitation), and always faster than the downloads! Since ssh is choppy just with slow typing, I don't believe it's a throttling-type problem either; that's not a lot of bandwidth. What I've tried Swapping all "good" and "bad" cables Re-plugging "bad" cable from D-Link to Netgear and watching it be the "good" cable pulling cables away from power lines Verify that the Mac auto-detects the D-Link as gigE Try to verify the link speed of the D-Link <- Netgear connection, but the firmware doesn't report that Verify that the D-Link sees no TX/RX errors or collisions Use different Ethernet ports on both Netgear and D-Link Reset the D-Link to factory settings Upgrade the D-Link firmware from 1.21 to 1.35NA, 2010/11/12, the latest Reboot everything at least once On the Mac, disable Wi-Fi during the Ethernet tests, and unplug Ethernet during the Wi-Fi tests Using iStumbler, verify that the D-Link isn't picking overloaded Wi-Fi channels (usually just 1-5 neighbors on my and adjacent channels, average for my apt building) Verify that the only client connected to the Wi-Fi was the iPhone Verify that nothing was being chatty on my network according to the WISH log Enable and disable all sorts of D-Link settings, including forcing WAN auto-detect to gigE So. I don't mind buying a new access point—I wouldn't mind having a dual-link network—but as a guy who's been networking since gated v4 was a drastic rewrite, and who often used physical sniffers in the days before Wireshark, I'm baffled. I hate being baffled. What could I possibly have changed that would result in this? How can I measure it? All I can think of is a static zap—thick carpet, socks, HVAC—but I didn't feel one, and does that really happen anymore? Can I test if it's Ethernet vs. TCP layer slowness? I'm not familiar with modern network utilities; it's hard to Google without hitting "Q: Why is my network slow? A: Is your microwave on?" If I don't get an answer here, will someone big and powerful help me migrate it to serverfault without getting screamed back here? In the words of Inigo Montoya, "I must know." Don't get all Dread Pirate Roberts on me.

• Sporadic unspecific kernel panic

  I'm experiencing seldom (so far about once a month) hard crashes on our ubuntu server 10.04 LTS box. The box itself is quite old (Dell PowerEdge 750 from 2004, Pentium4 2.8 GHz). I set up netconsole after it crashed twice last thursday and was able to extract the following output: [ 9354.062473] invalid opcode: 0000 [#1] SMP [ 9354.062516] last sysfs file: /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/uevent [ 9354.062555] Modules linked in: ppdev adm1026 hwmon_vid i2c_i801 bridge stp dcdbas psmouse serio_raw netconsole configfs shpchp lp parport usbhid hid e1000 [ 9354.062685] [ 9354.062704] Pid: 3988, comm: rsync Not tainted 2.6.38-12-generic-pae #51~lucid1-Ubuntu Dell Computer Corporation PowerEdge 750 /0R1479 [ 9354.062773] EIP: 0060:[<c104fef1>] EFLAGS: 00010046 CPU: 1 [ 9354.062802] EIP is at check_preempt_wakeup+0x181/0x250 [ 9354.062826] EAX: 00000002 EBX: f2a10ccc ECX: 00000000 EDX: 00000002 [ 9354.062850] ESI: f1db71cc EDI: f1db71a0 EBP: f1dbdea8 ESP: f1dbde8c [ 9354.062875] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 9354.062900] Process rsync (pid: 3988, ti=f1dbc000 task=f1db71a0 task.ti=f1dbc000) [ 9354.062933] Stack: [ 9354.062951] 0053ea60 f7907680 f28da840 f2a10ca0 c153ea60 f7907680 c153ea60 f1dbdebc [ 9354.063019] c103f98a f2a10ca0 f7907680 00000001 f1dbdef8 c104f97f 00000000 f2f0bacc [ 9354.063088] f7904338 00000001 00000003 00000000 f2f0bacc 00000001 00000001 00000086 [ 9354.063157] Call Trace: [ 9354.063183] [<c103f98a>] check_preempt_curr+0x6a/0x80 [ 9354.063210] [<c104f97f>] try_to_wake_up+0x5f/0x3f0 [ 9354.063236] [<c1077a00>] ? hrtimer_wakeup+0x0/0x30 [ 9354.063261] [<c104fd64>] wake_up_process+0x14/0x20 [ 9354.063286] [<c1077a1d>] hrtimer_wakeup+0x1d/0x30 [ 9354.063310] [<c1077f4a>] __run_hrtimer+0x7a/0x1c0 [ 9354.063336] [<c107dbad>] ? ktime_get+0x6d/0x110 [ 9354.063360] [<c1078310>] hrtimer_interrupt+0x120/0x2b0 [ 9354.063390] [<c1535c36>] smp_apic_timer_interrupt+0x56/0x8a [ 9354.063418] [<c152f459>] apic_timer_interrupt+0x31/0x38 [ 9354.063446] [<c1520000>] ? mca_attach_bus+0x5/0xc0 [ 9354.063469] Code: 8b 9b 20 01 00 00 8b 86 24 01 00 00 3b 83 24 01 00 00 75 e6 85 db 0f 84 a3 00 00 00 89 da 89 f0 e8 75 f6 fe ff 83 f8 01 0f 85 00 <fe> ff ff 89 f8 e8 95 f9 fe ff 8b 5e 1c 85 db 0f 84 e4 fe ff ff [ 9354.063804] EIP: [<c104fef1>] check_preempt_wakeup+0x181/0x250 SS:ESP 0068:f1dbde8c [ 9354.064231] ---[ end trace 290689cea65aea7f ]--- [ 9354.064290] Kernel panic - not syncing: Fatal exception in interrupt [ 9354.064352] Pid: 3988, comm: rsync Tainted: G D 2.6.38-12-generic-pae #51~lucid1-Ubuntu [ 9354.064424] Call Trace: [ 9354.064481] [<c152c057>] ? panic+0x5c/0x15b [ 9354.064539] [<c15302bd>] ? oops_end+0xcd/0xd0 [ 9354.064539] [<c100d9e4>] ? die+0x54/0x80 [ 9354.064539] [<c152f926>] ? do_trap+0x96/0xc0 [ 9354.064539] [<c100ba00>] ? do_invalid_op+0x0/0xa0 [ 9354.064539] [<c100ba8b>] ? do_invalid_op+0x8b/0xa0 [ 9354.064539] [<c104fef1>] ? check_preempt_wakeup+0x181/0x250 [ 9354.064539] [<c144884d>] ? __kfree_skb+0x3d/0x90 [ 9354.064539] [<c1042ae7>] ? update_curr+0x247/0x2a0 [ 9354.064539] [<c10447bb>] ? update_cfs_load+0x11b/0x2d0 [ 9354.064539] [<c1042a25>] ? update_curr+0x185/0x2a0 [ 9354.064539] [<c152f6bf>] ? error_code+0x67/0x6c [ 9354.064539] [<c104fef1>] ? check_preempt_wakeup+0x181/0x250 [ 9354.064539] [<c103f98a>] ? check_preempt_curr+0x6a/0x80 [ 9354.064539] [<c104f97f>] ? try_to_wake_up+0x5f/0x3f0 [ 9354.064539] [<c1077a00>] ? hrtimer_wakeup+0x0/0x30 [ 9354.064539] [<c104fd64>] ? wake_up_process+0x14/0x20 [ 9354.064539] [<c1077a1d>] ? hrtimer_wakeup+0x1d/0x30 [ 9354.064539] [<c1077f4a>] ? __run_hrtimer+0x7a/0x1c0 [ 9354.064539] [<c107dbad>] ? ktime_get+0x6d/0x110 [ 9354.064539] [<c1078310>] ? hrtimer_interrupt+0x120/0x2b0 [ 9354.064539] [<c1535c36>] ? smp_apic_timer_interrupt+0x56/0x8a [ 9354.064539] [<c152f459>] ? apic_timer_interrupt+0x31/0x38 [ 9354.064539] [<c1520000>] ? mca_attach_bus+0x5/0xc0 Googling for this issue didn't really turn up anything useful (most stuff I found was related to btrfs, but I don't use that, although the module exists and is sometimes loaded). From experience it might have to do with relatively heavy I/O, as two of the panics happened during a backup procedure. Kernel is 2.6.38-12-generic-pae, but I'm pretty sure I also saw panics on 2.6.32. I meanwhile upgraded to 3.0.0-17-generic-pae and am waiting for the next crash ;-) I'm at a loss here, so any pointers where to look for the cause or what it could be would be great :-) Thanks !

• OPTIONS * HTTP/1.0 APACHE

  - by Abby E

  I been noticing a lot lately in my /server-status the OPTIONS * HTTP/1.0 has been coming up lately a lot. I'm running Ubuntu 12.04 with the latest apache/php/MySQL. I'm not sure what they're for but I would like to see if it would effect performance by some how turning it off. I host some stuff that is accessed a lot that uses PHP/MySQL (600 rps). I'm not sure what it's there for but I do see the local 127.0.0.1 IP, so I assume it's something running local. What is it? How do your turn it off? If turned off how would it effect performance?

• Someone tried to hack my Node.js server, need to understand a GET request in the logs

  - by Akay

  Alright, so I left my Node.js server alone for a while and came back to find some really interesting stuff in the logs. Apparently some moron from China or Poland tried to hack my server using directory traversal and what not, while it seems though he did not succeed I am unable understand few entries in the log. This is the output of a "hohup.out" file. The attack starts, apparently he is trying to find out some console entry in my server. All of which fail and return a 404.

How did the hacker even manage to send a GET request to my server such that "http://www.google.com" shows up in the log while my server is simply an API that works on relative URLs such as "/api/login". And, while I looked up the OPTIONS, TRACE and PROPFIND HTTP requests that my server has logged it would be great if someone could explain what exactly was the hacker trying to achieve by using these verbs? Also what in the world does "[90m [32m [90m1ms - 240b[0m" mean? The "ms" makes sense, probably milliseconds for the request, rest I am unable to understand. Thank you!

• How to decrypt an encrypted Apple iTunes iPhone backup?

  - by afit

  I've been asked by a number of unfortunate iPhone users to help them restore data from their iTunes backups. This is easy when they are unencrypted, but not when they are encrypted, whether or not the password is known. As such, I'm trying to figure out the encryption scheme used on mddata and mdinfo files when encrypted. I have no problems reading these files otherwise, and have built some robust C# libraries for doing so. (If you're able to help, I don't care which language you use. It's the principle I'm after here!) The Apple "iPhone OS Enterprise Deployment Guide" states that "Device backups can be stored in encrypted format by selecting the Encrypt iPhone Backup option in the device summary pane of iTunes. Files are encrypted using AES128 with a 256-bit key. The key is stored securely in the iPhone keychain." That's a pretty good clue, and there's some good info here on Stackoverflow on iPhone AES/Rijndael interoperability suggesting a keysize of 128 and CBC mode may be used. Aside from any other obfuscation, a key and initialisation vector (IV)/salt are required. One might assume that the key is a manipulation of the "backup password" that users are prompted to enter by iTunes and passed to "AppleMobileBackup.exe", padded in a fashion dictated by CBC. However, given the reference to the iPhone keychain, I wonder whether the "backup password" might not be used as a password on an X509 certificate or symmetric private key, and that the certificate or private key itself might be used as the key. (AES and the iTunes encrypt/decrypt process is symmetric.) The IV is another matter, and it could be a few things. Perhaps it's one of the keys hard-coded into iTunes, or into the devices themselves. Although Apple's comment above suggests the key is present on the device's keychain, I think this isn't that important. One can restore an encrypted backup to a different device, which suggests all information relevant to the decryption is present in the backup and iTunes configuration, and that anything solely on the device is irrelevant and replacable in this context. So where might be the key be? I've listed paths below from a Windows machine but it's much of a muchness whichever OS we use. The "\appdata\Roaming\Apple Computer\iTunes\itunesprefs.xml" contains a PList with a "Keychain" dict entry in it. The "\programdata\apple\Lockdown\09037027da8f4bdefdea97d706703ca034c88bab.plist" contains a PList with "DeviceCertificate", "HostCertificate", and "RootCertificate", all of which appear to be valid X509 certs. The same file also appears to contain asymmetric keys "RootPrivateKey" and "HostPrivateKey" (my reading suggests these might be PKCS #7-enveloped). Also, within each backup there are "AuthSignature" and "AuthData" values in the Manifest.plist file, although these appear to be rotated as each file gets incrementally backed up, suggested they're not that useful as a key, unless something really quite involved is being done. There's a lot of misleading stuff out there suggesting getting data from encrypted backups is easy. It's not, and to my knowledge it hasn't been done. Bypassing or disabling the backup encryption is another matter entirely, and is not what I'm looking to do. This isn't about hacking apart the iPhone or anything like that. All I'm after here is a means to extract data (photos, contacts, etc.) from encrypted iTunes backups as I can unencrypted ones. I've tried all sorts of permutations with the information I've put down above but got nowhere. I'd appreciate any thoughts or techniques I might have missed.
