• FreeBSD 8.0 - Macbook: Trying to Connect to Wireless

  - by Koroviev

  What Happened A few days ago I installed FreeBSD 8from USB to my Macbook (Core Duo, 13"). The first thing I wanted to do was get my GUI back. I'm new to FreeBSD and it's my first time off of mac or windows, so I had some learning to do. I tried to a make clean install of xorg with ports but it returned many "No address record" errors. I realised I hadn't configured network settings and then the fun started. I ran ifconfig and it found 5 devices: msk0, ath0, fwe0, fwip0, lo0. * ath0 was identified as media: IEEE 802.11 Wireless Ethernet autoselect so it was clear which one I needed. From what I gathered, there are 3 files and two processes involved here: /boot/loader.conf /etc/wpa_supplicant.conf /etc/rc.conf /etc/rc.d/netif wpa_supplicant (which is a part of the former too) I'm certain it's a big simplification, so correct me if I'm wrong here. What I Tried I configured /boot/loader.conf with the few basic settings, and I'm most sure that this file is okay. The other 2 were more puzzling. I tried to make a network package in wpa_supplicant.conf. I found the ssid of the router, but the security wasn't so easy. The routers configuration on security is set to "Auto", with no explanation given. Other options are there, but Auto is selected. Another laptop uses WEP to connect (it's Vista, so I don't know how to get any more info than that), but I never configured it to do it. There's a string labled "wireless key" on the bottom of the router which I entered to set it up a new machine on the network (Windows and Macs, so it was simplified). I never had to choose a security type and only learned about them by installing FreeBSD. So perhaps WEP is what "Auto" means, but I can't find any other evidence. wpa_supplicant.conf seemed to never be correctly configured. I always got errors related to it and WPA_supplicant doesn't work. It gave me "Can't disable/enable WPA in the driver" errors and more once when I enabled -d -d. This was when I was trying some suspect configurations in rc.conf though. Usually it does nothing except hijack the shell and print "CTRL-SCAN-EVENT-RESULT" every 10 seconds. I learned how to clone the ath0 device to a wlandev interface (wlan0). ath0 is associated to it and their connection seems to go smoothly. But the wlan0's connection to the network is the problem. I couldn't create this with rc.conf, I do something wrong and get ifconfig: create: bad value errors whenever it's parsed. I did it via the shell instead. What Now? I scanned with wlan0 today: ifconfig wlan0 list scan It shows my router, even my neighbour's router. It was a relief to finally get some feedback. So wlan0 is UP and detects the router, but it is always status: no carrier. It can't associate with it and I can't figure out why. Running /etc/rc.d/netif start returns almost the same result as ifconfig would. It shows lo0 and wlan0, and sometimes ath0. I still not sure what lo0 is doing. So; how do I associate with it? We can assume it's WEP security based on how the other laptop is setup. I'll give every relevant output here. After boot, with a blank rc.conf this is what ifconfig returns: msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=11a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4> ether 00:17:f2:29:89:3b media: Ethernet autoselect ath0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 02:17:f2:60:ad:7e ch 1 dma -1 fwip0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 lladdr 0.17.f2.ff.fe.60.ad.7e.a.2.ff.fe.0.0.0.0 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 I run: ifconfig wlan0 create wlandev ath0 It returns: wlan0: bpf attached wlan0: bpf attached wlan0: Ethernet address: xx:xx:xx:xx:xx:xx Ifconfig now returns: msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=11a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4> ether 00:17:f2:29:89:3b media: Ethernet autoselect ath0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 02:17:f2:60:ad:7e ch 1 dma -1 fwip0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 lladdr 0.17.f2.ff.fe.60.ad.7e.a.2.ff.fe.0.0.0.0 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 wlan0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:16:cb:bb:fe:65 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier ssid "" channel 1 (2412 Mhz 11b) regdomain 106 indoor ecm authmode OPEN privacy OFF txpower 20 bmiss 7 scanvalid 60 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 1 wme burst bintval 0 I run: ifconfig wlan0 up ifconfig wlan0 scan It finds my router and displays its details. I can feed it my routers details now, using: ifconfig wlan0 key value key value ... They show up in wlan0 when I run ifconfig, but it still doesn't associate. What details should I feed it, what exactly is needed? What, if anything, should I have in /etc/wpa_supplicant.conf (and if that psk is needed, is it most likely the string I mentioned above)? If I define the ssid in wpa_supplicant.conf, should I still feed it to wlan0? What process should I then use to associate it? 5 .How should I add these things to rc.conf so it will automatically do this at boot? A huge thank you in advance for any help you can give, I've spent hours crawling about the shell and I've learned quite a bit from it (I finally got the hang of vi too, from all that editing). But the sooner this is fixed, the better. *P.S. I was, and still am, wondering where the extra three devices come from (the wireless and wired were all I expected to find). lo0 is up at each boot and /etc/rc.d/netif, I have no idea what it is and can't find it in dmesg. Resources: /etc/loader.conf: Code: if_ath_load="YES" wlan_wep_load="YES" wlan_ccmp_load="YES" wlan_tkip_load="YES" /etc/wpa_supplicant.conf (I emptied it of everything unnecessary, because I was just causing errors) network={ ssid="BTVOYAGER2110-1C" } /etc/rc.conf has no network settings, I commented them out because of errors. There was my attempt to clone ath0 and feed it info, but I did if via the shell instead. I've included the output of dmesg as an attachment, in case it's useful. I'd include the boot text (which appears before login) but I don't know how to catch it into a text file. If it's needed and somebody tells me how, I will (actually, even if it's not needed, how can I view it to read?).

• Does anyone really understand how HFSC scheduling in Linux/BSD works?

  - by Mecki

  I read the original SIGCOMM '97 PostScript paper about HFSC, it is very technically, but I understand the basic concept. Instead of giving a linear service curve (as with pretty much every other scheduling algorithm), you can specify a convex or concave service curve and thus it is possible to decouple bandwidth and delay. However, even though this paper mentions to kind of scheduling algorithms being used (real-time and link-share), it always only mentions ONE curve per scheduling class (the decoupling is done by specifying this curve, only one curve is needed for that). Now HFSC has been implemented for BSD (OpenBSD, FreeBSD, etc.) using the ALTQ scheduling framework and it has been implemented Linux using the TC scheduling framework (part of iproute2). Both implementations added two additional service curves, that were NOT in the original paper! A real-time service curve and an upper-limit service curve. Again, please note that the original paper mentions two scheduling algorithms (real-time and link-share), but in that paper both work with one single service curve. There never have been two independent service curves for either one as you currently find in BSD and Linux. Even worse, some version of ALTQ seems to add an additional queue priority to HSFC (there is no such thing as priority in the original paper either). I found several BSD HowTo's mentioning this priority setting (even though the man page of the latest ALTQ release knows no such parameter for HSFC, so officially it does not even exist). This all makes the HFSC scheduling even more complex than the algorithm described in the original paper and there are tons of tutorials on the Internet that often contradict each other, one claiming the opposite of the other one. This is probably the main reason why nobody really seems to understand how HFSC scheduling really works. Before I can ask my questions, we need a sample setup of some kind. I'll use a very simple one as seen in the image below: Here are some questions I cannot answer because the tutorials contradict each other: What for do I need a real-time curve at all? Assuming A1, A2, B1, B2 are all 128 kbit/s link-share (no real-time curve for either one), then each of those will get 128 kbit/s if the root has 512 kbit/s to distribute (and A and B are both 256 kbit/s of course), right? Why would I additionally give A1 and B1 a real-time curve with 128 kbit/s? What would this be good for? To give those two a higher priority? According to original paper I can give them a higher priority by using a curve, that's what HFSC is all about after all. By giving both classes a curve of [256kbit/s 20ms 128kbit/s] both have twice the priority than A2 and B2 automatically (still only getting 128 kbit/s on average) Does the real-time bandwidth count towards the link-share bandwidth? E.g. if A1 and B1 both only have 64kbit/s real-time and 64kbit/s link-share bandwidth, does that mean once they are served 64kbit/s via real-time, their link-share requirement is satisfied as well (they might get excess bandwidth, but lets ignore that for a second) or does that mean they get another 64 kbit/s via link-share? So does each class has a bandwidth "requirement" of real-time plus link-share? Or does a class only have a higher requirement than the real-time curve if the link-share curve is higher than the real-time curve (current link-share requirement equals specified link-share requirement minus real-time bandwidth already provided to this class)? Is upper limit curve applied to real-time as well, only to link-share, or maybe to both? Some tutorials say one way, some say the other way. Some even claim upper-limit is the maximum for real-time bandwidth + link-share bandwidth? What is the truth? Assuming A2 and B2 are both 128 kbit/s, does it make any difference if A1 and B1 are 128 kbit/s link-share only, or 64 kbit/s real-time and 128 kbit/s link-share, and if so, what difference? If I use the seperate real-time curve to increase priorities of classes, why would I need "curves" at all? Why is not real-time a flat value and link-share also a flat value? Why are both curves? The need for curves is clear in the original paper, because there is only one attribute of that kind per class. But now, having three attributes (real-time, link-share, and upper-limit) what for do I still need curves on each one? Why would I want the curves shape (not average bandwidth, but their slopes) to be different for real-time and link-share traffic? According to the little documentation available, real-time curve values are totally ignored for inner classes (class A and B), they are only applied to leaf classes (A1, A2, B1, B2). If that is true, why does the ALTQ HFSC sample configuration (search for 3.3 Sample configuration) set real-time curves on inner classes and claims that those set the guaranteed rate of those inner classes? Isn't that completely pointless? (note: pshare sets the link-share curve in ALTQ and grate the real-time curve; you can see this in the paragraph above the sample configuration). Some tutorials say the sum of all real-time curves may not be higher than 80% of the line speed, others say it must not be higher than 70% of the line speed. Which one is right or are they maybe both wrong? One tutorial said you shall forget all the theory. No matter how things really work (schedulers and bandwidth distribution), imagine the three curves according to the following "simplified mind model": real-time is the guaranteed bandwidth that this class will always get. link-share is the bandwidth that this class wants to become fully satisfied, but satisfaction cannot be guaranteed. In case there is excess bandwidth, the class might even get offered more bandwidth than necessary to become satisfied, but it may never use more than upper-limit says. For all this to work, the sum of all real-time bandwidths may not be above xx% of the line speed (see question above, the percentage varies). Question: Is this more or less accurate or a total misunderstanding of HSFC? And if assumption above is really accurate, where is prioritization in that model? E.g. every class might have a real-time bandwidth (guaranteed), a link-share bandwidth (not guaranteed) and an maybe an upper-limit, but still some classes have higher priority needs than other classes. In that case I must still prioritize somehow, even among real-time traffic of those classes. Would I prioritize by the slope of the curves? And if so, which curve? The real-time curve? The link-share curve? The upper-limit curve? All of them? Would I give all of them the same slope or each a different one and how to find out the right slope? I still haven't lost hope that there exists at least a hand full of people in this world that really understood HFSC and are able to answer all these questions accurately. And doing so without contradicting each other in the answers would be really nice ;-)

• UAC being turned off once a day on Windows 7

  - by Mehper C. Palavuzlar

  I have strange problem on my HP laptop. This began to happen recently. Whenever I start my machine, Windows 7 Action Center displays the following warning: You need to restart your computer for UAC to be turned off. Actually, this does not happen if it happened once on a specific day. For example, when I start the machine in the morning, it shows up; but it never shows up in the subsequent restarts within that day. On the next day, the same thing happens again. I never disable UAC, but obviously some rootkit or virus causes this. As soon as I get this warning, I head for the UAC settings, and re-enable UAC to dismiss this warning. This is a bothersome situation as I can't fix it. First, I have run a full scan on the computer for any probable virus and malware/rootkit activity, but TrendMicro OfficeScan said that no viruses have been found. I went to an old Restore Point using Windows System Restore, but the problem was not solved. What I have tried so far (which couldn't find the rootkit): TrendMicro OfficeScan Antivirus AVAST Malwarebytes' Anti-malware Ad-Aware Vipre Antivirus GMER TDSSKiller (Kaspersky Labs) HiJackThis RegRuns UnHackMe SuperAntiSpyware Portable Tizer Rootkit Razor (*) Sophos Anti-Rootkit SpyHunter 4 There are no other strange activities on the machine. Everything works fine except this bizarre incident. What could be the name of this annoying rootkit? How can I detect and remove it?

8204 bytes As suggested in this very similar question, I have run full scans (+boot time scans) with RegRun and UnHackMe, but they also did not find anything. I have carefully examined all entries in the Event Viewer, but there's nothing wrong. Now I know that there is a hidden trojan (rootkit) on my machine which seems to disguise itself quite successfully. Note that I don't have the chance to remove the HDD, or reinstall the OS as this is a work machine subjected to certain IT policies on a company domain. Despite all my attempts, the problem still remains. I strictly need a to-the-point method or a pukka rootkit remover to remove whatever it is. I don't want to monkey with the system settings, i.e. disabling auto runs one by one, messing the registry, etc. EDIT 2: I have found an article which is closely related to my trouble: Malware can turn off UAC in Windows 7; “By design” says Microsoft. Special thanks(!) to Microsoft. In the article, a VBScript code is given to disable UAC automatically: '// 1337H4x Written by _____________ '// (12 year old) Set WshShell = WScript.CreateObject("WScript.Shell") '// Toggle Start menu WshShell.SendKeys("^{ESC}") WScript.Sleep(500) '// Search for UAC applet WshShell.SendKeys("change uac") WScript.Sleep(2000) '// Open the applet (assuming second result) WshShell.SendKeys("{DOWN}") WshShell.SendKeys("{DOWN}") WshShell.SendKeys("{ENTER}") WScript.Sleep(2000) '// Set UAC level to lowest (assuming out-of-box Default setting) WshShell.SendKeys("{TAB}") WshShell.SendKeys("{DOWN}") WshShell.SendKeys("{DOWN}") WshShell.SendKeys("{DOWN}") '// Save our changes WshShell.SendKeys("{TAB}") WshShell.SendKeys("{ENTER}") '// TODO: Add code to handle installation of rebound '// process to continue exploitation, i.e. place something '// evil in Startup folder '// Reboot the system '// WshShell.Run "shutdown /r /f" Unfortunately, that doesn't tell me how I can get rid of this malicious code running on my system. EDIT 3: Last night, I left the laptop open because of a running SQL task. When I came in the morning, I saw that UAC was turned off. So, I suspect that the problem is not related to startup. It is happening once a day for sure no matter if the machine is rebooted.

• DNS Problems (NIGHTMARES!) with BIND and Virtualmin

  - by Nyxynyx

  I have a webserver (Ubuntu 12.04 with LAMP) using Virtualmin / Webmin. Because I just moved from a Cpanel system, I am having a nightmare configuring the DNS! Using intoDNS.com, the failed reports are: Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records. DNS servers responded ERROR: One or more of your nameservers did not respond: The ones that did not respond are: 123.123.123.123 213.251.188.141x Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. Missing nameservers reported by your nameserver You should already know that your NS records at your nameservers are missing, so here it is again: ns1.mydomain.com. sdns2.ovh.net. SOA record No valid SOA record came back! MX Records WWW A Record ERROR: I could not get any A records for www.mydomain.com! Step-by-Step of my Attempt In my domain registrar (Namecheap), I registered ns1.mydomain.com as a nameserver, pointing to the IP address of my web server which is running bind9. The domain is setup with DNS ns1.mydomain.com and sdns2.ovh.net. sdns2.ovh.net is a secondary DNS server (SLAVE and pointing mydomain.com to the IP address of my web server) Webserver domain: mydomain.com Webserver hostname: ns4000000.ip-123-123-123.net Webserver IP: 123.123.123.123 Under Virtualmin, I edited the default Virtual server template, BIND DNS records for new domains: ns1.mydomain.com Master DNS server hostname: ns1.mydomain.com Next I created a Virtual server using that server template. This is what I've done but its still not working! Any ideas? I've been stuck for days, thank you for all your help! service bind9 status * bind9 is running lsof -i :53 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME named 6966 bind 20u IPv6 338583 0t0 TCP *:domain (LISTEN) named 6966 bind 21u IPv4 338588 0t0 TCP localhost.localdomain:domain (LISTEN) named 6966 bind 22u IPv4 338590 0t0 TCP ns4000000.ip-123-123-123.net:domain (LISTEN) named 6966 bind 512u IPv6 338582 0t0 UDP *:domain named 6966 bind 513u IPv4 338587 0t0 UDP localhost.localdomain:domain named 6966 bind 514u IPv4 338589 0t0 UDP ns4000000.ip-123-123-123.net:domain /etc/resolv.con (Not sure how 213.186.33.99 got here) nameserver 127.0.0.1 nameserver 213.186.33.99 search ovh.net host 123.123.123.123 (my web server's IP) 13.60.245.198.in-addr.arpa domain name pointer ns4000000.ip-123-123-123.net. nslookup 213.186.33.99 Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: 99.33.186.213.in-addr.arpa name = cdns.ovh.net.

  Hello everyone, Lately I had to reinstall my development site on my ubuntu machine since my system crashed after an os update. 4 days later my site is still not running as it should. Whenever i do an action which has in it an action on a database, it stops working.

I CAN login to my database command line with the given username and password. Update: today i decided to investigate on my http request and i came to an error 500. My apache logs don't give any related information, I think. I posted the logs above. Any idea's?

• Windows periodically disconnects, reconnects to the network

  - by einpoklum

  My setup: I have a PC with a Gigabyte GA-MA78S2H motherboard (Realtek Gigabit wired Ethernet on-board). I have the latest drivers (at least the latest driver for the NIC. I'm connecting via an Edimax BR-6216Mg (again, wired connection). For some reason I experience short periodic disconnects and reconnects. Specifically, Skype disconnects, tries to connect, succeeds after a short while; incoming SFTP sessions get dropped; using a browser, I sometime get stuck in the DNS lookup or connection to the website and a page won't load. A couple of seconds later, a reload works. All this happens with Windows XP SP3. With Windows 7, it also happens.

Tried reducing the MTU (used a utility called Dr. TCP); there was no effect. I updated my board BIOS revision (which caused all the HW to be "reinstalled" or re-identified - successfully). I installed another NIC, and tried switching to it - same effect with the on-board NIC. A while back I tried another router (although it was an Edimax model) - same problem. Connected the computer directly, with no router. Same problem. ping -t to the router (192.168.0.254) gives pongs, nothing is lost, and time is < 1 ms almost always (sometimes it says 1 or 2 ms). This is the case also during the disconnects.

• Gmail rejects emails. Openspf.net fails the tests

  - by pablomedok

  I've got a problem with Gmail. It started after one of our trojan infected PCs sent spam for one day from our IP address. We've fixed the problem, but we got into 3 black lists. We've fixed that, too. But still every time we send an email to Gmail the message is rejected: So I've checked Google Bulk Sender's guide once again and found an error in our SPF record and fixed it. Google says everything should become fine after some time, but this doesn't happen. 3 weeks already passed but we still can't send emails to Gmail. Our MX setup is a bit complex, but not too much: We have a domain name delo-company.com, it has it's own mail @delo-company.com (this one is fine, but the problems are with sub-domain name corp.delo-company.com). Delo-company.com domain has several DNS records for the subdomain: corp A 82.209.198.147 corp MX 20 corp.delo-company.com corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" (I set ~all for testing purposes only, it was -all before that) These records are for our corporate Exchange 2003 server at 82.209.198.147. Its LAN name is s2.corp.delo-company.com so its HELO/EHLO greetings are also s2.corp.delo-company.com. To pass EHLO check we've also created some records in delo-company.com's DNS: s2.corp A 82.209.198.147 s2.corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" As I understand SPF verifications should be passed in this way: Out server s2 connects to MX of the recepient (Rcp.MX): EHLO s2.corp.delo-company.com Rcp.MX says Ok, and makes SPF check of HELO/EHLO. It does NSlookup for s2.corp.delo-company.com and gets the above DNS-records. TXT records says that s2.corp.delo-company.com should be only from IP 82.209.198.147. So it should be passed. Then our s2 server says RCPT FROM: Rcp.MX` server checks it, too. The values are the same so they should also be positive. Maybe there is also a rDNS check, but I'm not sure what is checked HELO or RCPT FROM. Our PTR record for 82.209.198.147 is: 147.198.209.82.in-addr.arpa. 86400 IN PTR s2.corp.delo-company.com. To me everything looks fine, but anyway all emails are rejected by Gmail. So, I've checked MXtoolbox.com - it says everything is fine, I passed http://www.kitterman.com/spf/validate.html Python check, I did 25port.com email test. It's fine, too: Return-Path: <[email protected]> Received: from s2.corp.delo-company.com (82.209.198.147) by verifier.port25.com id ha45na11u9cs for <[email protected]>; Fri, 2 Mar 2012 13:03:21 -0500 (envelope-from <[email protected]>) Authentication-Results: verifier.port25.com; spf=pass [email protected] Authentication-Results: verifier.port25.com; domainkeys=neutral (message not signed) [email protected] Authentication-Results: verifier.port25.com; dkim=neutral (message not signed) Authentication-Results: verifier.port25.com; sender-id=pass [email protected] Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01CCF89E.BE02A069" Subject: test Date: Fri, 2 Mar 2012 21:03:15 +0300 X-MimeOLE: Produced By Microsoft Exchange V6.5 Message-ID: <[email protected]> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: test Thread-Index: Acz4jS34oznvbyFQR4S5rXsNQFvTdg== From: =?koi8-r?B?89XQ0tXOwMsg8MHXxcw=?= <[email protected]> To: <[email protected]> I also checked with [email protected], but it FAILs all the time, no matter which SPF records I make: <s2.corp.delo-company.com #5.7.1 smtp;550 5.7.1 <[email protected]>: Recipient address rejected: SPF Tests: Mail-From Result="softfail": Mail From="[email protected]" HELO name="s2.corp.delo-company.com" HELO Result="softfail" Remote IP="82.209.198.147"> I've filled Gmail form twice, but nothing happens.

• Moving the swapfiles to a dedicated partition in Snow Leopard

  - by e.James

  I have been able to move Apple's virtual memory swapfiles to a dedicated partition on my hard drive up until now. The technique I have been using is described in a thread on forums.macosxhints.com. However, with the developer preview of Snow Leopard, this method no longer works. Does anyone know how it could be done with the new OS? Update: I have marked dblu's answer as accepted even though it didn't quite work because he gave excellent, detailed instructions and because his suggestion to use plutil ultimately pointed me in the right direction. The complete, working solution is posted here in the question because I don't have enough reputation to edit the accepted answer. Complete solution: 1. Open Terminal and make a backup copy of Apple's default dynamic_pager.plist: $ cd /System/Library/LaunchDaemons $ sudo cp com.apple.dynamic_pager.plist{,_bak} 2. Convert the plist from binary to plain XML: $ sudo plutil -convert xml1 com.apple.dynamic_pager.plist 3. Open the converted plist with your text editor of choice. (I use pico, see dblu's answer for an example using vim): $ sudo pico -w com.apple.dynamic_pager.plist It should look as follows: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs$ <plist version="1.0"> <dict> <key>EnableTransactions</key> <true/> <key>HopefullyExitsLast</key> <true/> <key>Label</key> <string>com.apple.dynamic_pager</string> <key>OnDemand</key> <false/> <key>ProgramArguments</key> <array> <string>/sbin/dynamic_pager</string> <string>-F</string> <string>/private/var/vm/swapfile</string> </array> </dict> </plist> 4. Change the ProgramArguments array (lines 13 through 18) so that it launches an intermediate shell script instead of launching dynamic_pager directly. See note #1 for details on why this is necessary. <key>ProgramArguments</key> <array> <string>/sbin/dynamic_pager_init</string> </array> 5. Save the plist, and return to the terminal prompt. Using pico, the commands would be: <ctrl+o> to save the file <enter> to accept the same filename (com.apple.dynamic_pager.plist) <ctrl+x> to exit 6. Convert the modified plist back to binary: $ sudo plutil -convert binary1 com.apple.dynamic_pager.plist 7. Create the intermediate shell script: $ cd /sbin $ sudo pico -w dynamic_pager_init The script should look as follows (my partition is called 'Swap', and I chose to put the swapfiles in a hidden directory on that partition, called '.vm' be sure that the directory you specify actually exists): Update: This version of the script makes use of wait4path as suggested by ZILjr: #!/bin/bash #launch Apple's dynamic_pager only when the swap volume is mounted echo "Waiting for Swap volume to mount"; wait4path /Volumes/Swap; echo "Launching dynamic pager on volume Swap"; /sbin/dynamic_pager -F /Volumes/Swap/.vm/swapfile; 8. Save and close dynamic_pager_init (same commands as step 5) 9. Modify permissions and ownership for dynamic_pager_init: $ sudo chmod a+x-w /sbin/dynamic_pager_init $ sudo chown root:wheel /sbin/dynamic_pager_init 10. Verify the permissions on dynamic_pager_init: $ ls -l dynamic_pager_init -r-xr-xr-x 1 root wheel 6 18 Sep 15:11 dynamic_pager_init 11. Restart your Mac. If you run into trouble, switch to verbose startup mode by holding down Command-v immediately after the startup chime. This will let you see all of the startup messages that appear during startup. If you run into even worse trouble (i.e. you never see the login screen), hold down Command-s instead. This will boot the computer in single-user mode (no graphical UI, just a command prompt) and allow you to restore the backup copy of com.apple.dynamic_pager.plist that you made in step 1. 12. Once the computer boots, fire up Terminal and verify that the swap files have actually been moved: $ cd /Volumes/Swap/.vm $ ls -l You should see something like this: -rw------- 1 someUser staff 67108864 18 Sep 12:02 swapfile0 13. Delete the old swapfiles: $ cd /private/var/vm $ sudo rm swapfile* 14. Profit! Note 1 Simply modifying the arguments to dynamic_pager in the plist does not always work, and when it fails, it does so in a spectacularly silent way. The problem stems from the fact that dynamic_pager is launched very early in the startup process. If your swap partition has not yet been mounted when dynamic_pager is first loaded (in my experience, this happens 99% of the time), then the system will fake its way through. It will create a symbolic link in your /Volumes directory which has the same name as your swap partition, but points back to the default swapfile location (/private/var/vm). Then, when your actual swap partition mounts, it will be given the name Swap 1 (or YourDriveName 1). You can see the problem by opening up Terminal and listing the contents of your /Volumes directory: $ cd /Volumes $ ls -l You will see something like this: drwxrwxrwx 11 yourUser staff 442 16 Sep 12:13 Swap -> private/var/vm drwxrwxrwx 14 yourUser staff 5 16 Sep 12:13 Swap 1 lrwxr-xr-x 1 root admin 1 17 Sep 12:01 System -> / Note that this failure can be very hard to spot. If you were to check for the swapfiles as I show in step 12, you would still see them! The symbolic link would make it seem as though your swapfiles had been moved, even though they were actually being stored in the default location. Note 2 I was originally unable to get this to work in Snow Leopard because com.apple.dynamic_pager.plist was stored in binary format. I made a copy of the original file and opened it with Apple's Property List Editor (available with Xcode) in order to make changes, but this process added some extended attributes to the plist file which caused the system to ignore it and just use the defaults. As dblu pointed out, using plutil to convert the file to plain XML works like a charm. Note 3 You can check the Console application to see any messages that dynamic_pager_init echos to the screen. If you see the following lines repeated over and over again, there is a problem with the setup. I ran into these messages because I forgot to create the '.vm' directory that I specified in dynamic_pager_init. com.apple.launchd[1] (com.apple.dynamic_pager[176]) Exited with exit code: 1 com.apple.launchd[1] (com.apple.dynamic_pager) Throttling respawn: Will start in 10 seconds When everything is working properly, you may see the above message a couple of times, but you should also see the following message, and then no more of the "Throttling respawn" messages afterwards. com.apple.dynamic_pager[???] Launching dynamic pager on volume Swap This means that the script did have to wait for the partition to load, but in the end it was successful.

• How to run a DHCP service on Windows 7 Home

  - by Joshua Lim

  I'm trying to setup a DHCP server on Windows 7 Home, tried using a couple of freeware which I found on the Internet but none seemed to work. What I did: On the Windows 7 machine which I install the DHCP Server with the range 192.168.1.12-192.168.1.256. I set the Gigabit Ethernet adapter to a static IP address of 192.168.1.11 and subnet mask of 255.255.255.0. When I did an IP config, it showed.

  - by Jim

  My setup is: Intel® Core™ i7-2600 and RAM 16 GB DDR3 RAM varnish+nginx+php-fpm+apc for a not very heavy WordPress blog with W3 Total Cache and CDN My problem is that after 55 hits per second according to blitz.io varnish starts giving out timeouts. CPU usage at this time is hardly 1%. Free memory at all time remains 10GB+. I tried benchmarking php-fpm directly with result of 150hits/s without any timeouts. But after that the CPU usage goes 100% and it stops responding. Can you help me optimize it to handle more? As i understand nginx has nothing to do over here so i dont put its config. php-fpm config listen = /tmp/php5-fpm.sock listen.allowed_clients = 127.0.0.1 user = nginx group = nginx pm = dynamic pm.max_children = 150 pm.start_servers = 7 pm.min_spare_servers = 2 pm.max_spare_servers = 15 pm.max_requests = 500 slowlog = /var/log/php-fpm/www-slow.log php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on apc extension = apc.so apc.enabled=1 apc.shm_size=512MB apc.num_files_hint=0 apc.user_entries_hint=0 apc.ttl=7200 apc.use_request_time=1 apc.user_ttl=7200 apc.gc_ttl=3600 apc.cache_by_default=1 apc.filters apc.mmap_file_mask=/tmp/apc.XXXXXX apc.file_update_protection=2 apc.enable_cli=0 apc.max_file_size=1M apc.stat=1 apc.stat_ctime=0 apc.canonicalize=0 apc.write_lock=1 apc.report_autofilter=0 apc.rfc1867=0 apc.rfc1867_prefix =upload_ apc.rfc1867_name=APC_UPLOAD_PROGRESS apc.rfc1867_freq=0 apc.rfc1867_ttl=3600 apc.include_once_override=0 apc.lazy_classes=0 apc.lazy_functions=0 apc.coredump_unmap=0 apc.file_md5=0 apc.preload_path Varnish VCL backend default { .host = "127.0.0.1"; .port = "8080"; .connect_timeout = 6s; .first_byte_timeout = 6s; .between_bytes_timeout = 60s; } acl purgehosts { "localhost"; "127.0.0.1"; } # Called after a document has been successfully retrieved from the backend. sub vcl_fetch { # Uncomment to make the default cache "time to live" is 5 minutes, handy # but it may cache stale pages unless purged.

• MySQL query, 2 similar servers, 2 minute difference in execution times

  - by mr12086

  I had a similar question on stack overflow, but it seems to be more server/mysql setup related than coding. The queries below all execute instantly on our development server where as they can take upto 2 minutes 20 seconds. The query execution time seems to be affected by home ambiguous the LIKE string's are. If they closely match a country that has few matches it will take less time, and if you use something like 'ge' for germany - it will take longer to execute. But this doesn't always work out like that, at times its quite erratic. Sending data appears to be the culprit but why and what does that mean. Also memory on production looks to be quite low (free memory)?

• Set up tunnel to HE.net and now only ipv6.google.com works, but other sites ping fine.

  - by AndrejaKo

  I'm setting up IPv6 using my router which is running OpenWRT, version Backfire 10.03.1-rc4. I made a tunnel using Hurricane Electric's tunnel broker and set it up on the router and I'm using RADVD to hand out IPv6 addresses. My problem is that on computers on the network, I can only access ipv6.google.com using a browser, but other sites seem to be loading forever and won't open in any browser. I can ping and traceroute to them fine, but can't open them with a browser. I can open any site normally with a browser from the router. Stopping firewall service on the router doesn't help, so it's probably not a firewall issue. All AAAA records resolve fine, so it's probably not a DNS issue. Computers on the network get their IPv6 addresses fine, so it's probably not a radvd issue. Similar setup worked fine for SixXs, but I'm having problems with my PoP there, so I decided to move to HE. Here are some traceroutes: From a client computer: Tracing route to ipv6.he.net [2001:470:0:64::2] over a maximum of 30 hops: 1 <1 ms 1 ms 1 ms 2001:470:1f0b:de5::1 2 62 ms 63 ms 62 ms andrejako-1.tunnel.tserv6.fra1.ipv6.he.net [2001:470:1f0a:de5::1] 3 60 ms 60 ms 63 ms gige-g2-4.core1.fra1.he.net [2001:470:0:69::1] 4 63 ms 68 ms 68 ms 10gigabitethernet1-4.core1.ams1.he.net [2001:470:0:47::1] 5 84 ms 74 ms 76 ms 10gigabitethernet1-4.core1.lon1.he.net [2001:470:0:3f::1] 6 146 ms 147 ms 151 ms 10gigabitethernet4-4.core1.nyc4.he.net [2001:470:0:128::1] 7 200 ms 198 ms 202 ms 10gigabitethernet5-3.core1.lax1.he.net [2001:470:0:10e::1] 8 219 ms * 210 ms 10gigabitethernet2-2.core1.fmt2.he.net [2001:470:0:18d::1] 9 221 ms 338 ms 209 ms gige-g4-18.core1.fmt1.he.net [2001:470:0:2d::1] 10 206 ms 210 ms 207 ms ipv6.he.net [2001:470:0:64::2] Trace complete. and another from a cliet computer Tracing route to whatismyipv6.com [2001:4870:a24f:2::90] over a maximum of 30 hops: 1 7 ms 1 ms 1 ms 2001:470:1f0b:de5::1 2 69 ms 70 ms 63 ms AndrejaKo-1.tunnel.tserv6.fra1.ipv6.he.net [2001:470:1f0a:de5::1] 3 57 ms 65 ms 58 ms gige-g2-4.core1.fra1.he.net [2001:470:0:69::1] 4 73 ms 74 ms 75 ms 10gigabitethernet1-4.core1.ams1.he.net [2001:470:0:47::1] 5 71 ms 74 ms 76 ms 10gigabitethernet1-4.core1.lon1.he.net [2001:470:0:3f::1] 6 141 ms 149 ms 148 ms 10gigabitethernet2-3.core1.nyc4.he.net [2001:470:0:3e::1] 7 141 ms 147 ms 143 ms 10gigabitethernet1-2.core1.nyc1.he.net [2001:470:0:37::2] 8 144 ms 145 ms 142 ms 2001:504:1::a500:4323:1 9 226 ms 225 ms 218 ms 2001:4870:a240::2 10 220 ms 224 ms 219 ms 2001:4870:a240::2 11 219 ms 218 ms 220 ms 2001:4870:a24f::2 12 221 ms 222 ms 220 ms www.whatismyipv6.com [2001:4870:a24f:2::90] Trace complete.

• VPN still working after rebooting without client - DrayTek client shows "No Connection"

  - by HeavenCore

  My home network is a simple router + pc's setup, nothing fancy - the router has DHCP enabled for 192.168.0.X (255.255.255.0) and my PC picks up the address 192.168.0.82. There are no devices on my local lan in the 192.168.1.x range. On my pc i have the DrayTek VPN client, and a company i do some work for has a DrayTek Vigor router. The VPN client establishes a VPN to that remote company using an IPSec Tunnel (PreShared Key - no encryption) Last night i shut down my pc with the VPN tunnel still connected, when i turned my computer on this morning i accidentally clicked an RDP shortcut to 192.168.1.2 (a host in the remote company) and to my amazement it connected?!? I checked and the DrayTek VPN client isnt running, and when i did run it, it clearly shows "Status: No connection". confused as to how my machine can still talk to this remote machine i tried a trace: C:\Users\HeavenCore>tracert 192.168.1.2 Tracing route to C4SERVERII [192.168.1.2] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. 3 * * * Request timed out. 4 * * * Request timed out. 5 * * * Request timed out. 6 * * * Request timed out. 7 * * * Request timed out. 8 * * * Request timed out. 9 * * * Request timed out. 10 * * * Request timed out. 11 * * * Request timed out. 12 15 ms 21 ms 32 ms C4SERVERII [192.168.1.2] Trace complete.

My Question: Can an IPSec tunnel stay up some how after a reboot without use of the VPN client? (well, i can clearly see that it can) - where in windows is there visibility of this? how does my machine know where to route the packets? I appreciate any insights & thoughts!

• SQL IO and SAN troubles

  - by James

  We are running two servers with identical software setup but different hardware. The first one is a VM on VMWare on a normal tower server with dual core xeons, 16 GB RAM and a 7200 RPM drive. The second one is a VM on XenServer on a powerful brand new rack server, with 4 core xeons and shared storage. We are running Dynamics AX 2012 and SQL Server 2008 R2. When I insert 15 000 records into a table on the slow tower server (as a test), it does so in 13 seconds. On the fast server it takes 33 seconds. I re-ran these tests several times with the same results. I have a feeling it is some sort of IO bottleneck, so I ran SQLIO on both. Here are the results for the slow tower server: C:\Program Files (x86)\SQLIO>test.bat C:\Program Files (x86)\SQLIO>sqlio -kW -t8 -s120 -o8 -frandom -b8 -BH -LS C:\Tes tFile.dat sqlio v1.5.SG using

However, the 64 write test is incredibly slow on the rack server. (68 mb/sec on the slow tower vs 21 mb/s on the rack). The read speed for 64k also seems slow. Is this enough to say there is some sort of bottleneck with the shared storage? I need to know if I can take this evidence and say we need to launch an investigation into this. Any help is appreciated.

• WiFi & GbE Slow while Both Active.

  - by Mark Tomlin

  I'm having a problem with my WiFi network connection when I use my wired GbE connection concurrently on my Laptop. I'm using my WiFi for Internet access, and general web surfing and I'm using my GbE connection to connect to my PlayStation so I can stream media. The WiFi connection is via a Linksys 610N connected to my Cable Modem. Where as the GbE connection is a direct connection from my Ethernet port to the Ethernet port of the PS3 via a Cat-5 cable (no router in between this connection). As soon as I connect the cable from the PS3 to my Ethernet port on my Laptop the WiFi connection slows to a halt, but then allows for a connection to the web as normal but at much slower speeds for the things like BitTorrent that stops completely. It seems to me that Windows can't handle both connections at once. It will have both active but it can only accept and send packets on one device at one time. I can get WiFi connections to work to go to websites and the like, but once I use my GbE connection to share media between my Laptop and my PS3 the Wifi connection dies out and I no longer have access to the internet. I setup my connection on the PS3 and the Laptop following the insturctions posted here: http://forums.finalgear.com/problems/s14e01-ps3-size-problem-40642/#post1188132 And the following is the results of my ipconfig.

• Trying to configure HWIC-3G-HSPA

  - by user1174838

  I'm trying to configure a couple of Cisco 1941 routes. The are both identical routers. Each as a HWIC-1T (Smart Serial interface) and a HWIC-3G-HSPA 3G interface. These routers are to be sent to remote sites. We have connectivity to one of the sites but if remote site A gors down we lose connectivity to remote site B. The HWIC-1T is the primary WAN interface using frame relay joining the two remote sites We want the HWIC-3G-HSPA to be usable for direct connectivity from head office to remote site B, and also the HWIC-3G-HSPA is do be used for comms between the remote sites when the frame relay is down (happens quite a bit). I initialy tried to do dynamic routing using EIGRP however in my lab setup of laptop - 1941 - 1941 - laptop, I was unable to get end to end connectivity. I later settled on static routing and have got end to end connectivity but only over frame relay, not the HWIC-3G-HSPA.

Manually pinging the IP assigned (by the telco) to ce0/1/0 does bring the interface up. Any ideas? Thanks

Mail started flowing (Domain POP was successful) etc. etc. But I forgot to check if webmail worked from the outside admittedly. But the webservers at 172.21.37.17 and 172.21.37.24 still didn't respond from the outside world. Although I was able to PPTP VPN in on 321.321.39.10 (interface) which is the outside interface IP address. and it is static mapped to 172.21.37.20. So I'm thinking there must be something wrong with NAT somewhere? no response from 321.321.39.11 to 321.321.39.14.. Could anyone look over the config and please let me know what I've done wrong? Is there something I've missed? well obviously but.. please help! Thank you.

• Cannot open root device xvda1 or unknown-block(0,0)

  - by svoop

  I'm putting together a Dom0 and three DomU (all Gentoo) with kernel 3.5.7 and Xen 4.1.1. Each Dom has it's own md (md0 for Dom0, md1 for Dom1 etc). Dom0 works fine so far, however, I'm stuck trying to create DomUs. It appears the xvda1 device on DomU is not created or accessible: Parsing config file dom1 domainbuilder: detail: xc_dom_allocate: cmdline="root=/dev/xvda1 console=hvc0 root=/dev/xvda1 ro 3",

• network routing between mac & virtual XP

  - by Kevin

  Hi - I have a max laptop running XP inside VirtualBox. The network is setup to be a "Bridged Adapter" so that the IPs for both the host & guest OS's are assigned by my wireless routed. My guest XP has Nortel VPN connecting to corporate lan. When this is connected, I want to allow my host Mac OS to access the corporate network. But I'm struggling. Without Nortel VPN running, I can change routing on the mac so all traffic is sent via the guest XP - this works. But once I activate the VPN, this no longer works. If I try to change the routing on mac to run through the IP address assigned to the Nortel adapter, I get a "Network is unreachable" error. Below is the output from ipconfig /all on the guest XP OS. I'm beginning to believe that what I want to do is not possible because of the way Nortel secure the VPN - but before I give up I thought I'd post the problem here.

  I am troubleshooting the setup of Varnish 3.x on my Ubuntu server. I'm running Drupal 7 on two sites set up on the box, via named-based vhosts.

If I'm understanding correctly, this means the file isn't being returned from Varnish's cache. Is there a problem with my Varnish config?

• How do I prevent TCP connection freezes over an OpenVPN network?

  - by Jason R

  New details added at the end of this question; it's possible that I'm zeroing in on the cause. I have a UDP OpenVPN-based VPN set up in tap mode (I need tap because I need the VPN to pass multicast packets, which doesn't seem to be possible with tun networks) with a handful of clients across the Internet. I've been experiencing frequent TCP connection freezes over the VPN. That is, I will establish a TCP connection (e.g. an SSH connection, but other protocols have similar issues), and at some point during the session, it seems that traffic will cease being transmitted over that TCP session. This seems to be related to points at which large data transfers occur, such as if I execute an ls command in an SSH session, or if I cat a long log file. Some Google searches turn up a number of answers like this previous one on Server Fault, indicating that the likely culprit is an MTU issue: that during periods of high traffic, the VPN is trying to send packets that get dropped somewhere in the pipes between the VPN endpoints. The above-linked answer suggests using the following OpenVPN configuration settings to mitigate the problem: fragment 1400 mssfix This should limit the MTU used on the VPN to 1400 bytes and fix the TCP maximum segment size to prevent the generation of any packets larger than that. This seems to mitigate the problem a bit, but I still frequently see the freezes. I've tried a number of sizes as arguments to the fragment directive: 1200, 1000, 576, all with similar results. I can't think of any strange network topology between the two ends that could trigger such a problem: the VPN server is running on a pfSense machine connected directly to the Internet, and my client is also connected directly to the Internet at another location. One other strange piece of the puzzle: if I run the tracepath utility, then that seems to band-aid the problem. A sample run looks like: [~]$ tracepath -n 192.168.100.91 1: 192.168.100.90 0.039ms pmtu 1500 1: 192.168.100.91 40.823ms reached 1: 192.168.100.91 19.846ms reached Resume: pmtu 1500 hops 1 back 64 The above run is between two clients on the VPN: I initiated the trace from 192.168.100.90 to the destination of 192.168.100.91. Both clients were configured with fragment 1200; mssfix; in an attempt to limit the MTU used on the link. The above results would seem to suggest that tracepath was able to detect a path MTU of 1500 bytes between the two clients. I would assume that it would be somewhat smaller due to the fragmentation settings specified in the OpenVPN configuration. I found that result somewhat strange. Even stranger, however: if I have a TCP connection in the stalled state (e.g. an SSH session with a directory listing that froze in the middle), then executing the tracepath command shown above causes the connection to start up again! I can't figure out any reasonable explanation for why this would be the case, but I feel like this might be pointing toward a solution to ultimately eradicate the problem. Does anyone have any recommendations for other things to try? Edit: I've come back and looked at this a bit further, and have found only more confounding information: I set the OpenVPN connection to fragment at 1400 bytes, as shown above. Then, I connected to the VPN from across the Internet and used Wireshark to look at the UDP packets that were sent to the VPN server while the stall occurred. None were greater than the specified 1400 byte count, so the fragmentation seems to be functioning properly. To verify that even a 1400-byte MTU would be sufficient, I pinged the VPN server using the following (Linux) command: ping <host> -s 1450 -M do This (I believe) sends a 1450-byte packet with fragmentation disabled (I at least verified that it didn't work if I set it to an obviously-too-large value like 1600 bytes). These seem to work just fine; I get replies back from the host with no issue. So, maybe this isn't an MTU issue at all. I'm just confused as to what else it might be! Edit 2: The rabbit hole just keeps getting deeper: I've now isolated the problem a bit more. It seems to be related to the exact OS that the VPN client uses. I have successfully duplicated the problem on at least three Ubuntu machines (versions 12.04 through 13.04). I can reliably duplicate an SSH connection freeze within a minute or so by just cat-ing a large log file. However, if I do the same test using a CentOS 6 machine as a client, then I don't see the problem! I've tested using the exact same OpenVPN client version as I was using on the Ubuntu machines. I can cat log files for hours without seeing the connection freeze. This seems to provide some insight as to the ultimate cause, but I'm just not sure what that insight is. I have examined the traffic over the VPN using Wireshark. I'm not a TCP expert, so I'm not sure what to make of the gory details, but the gist is that at some point, a UDP packet gets dropped due to the limited bandwidth of the Internet link, causing TCP retransmissions inside the VPN tunnel. On the CentOS client, these retransmissions occur properly and things move on happily. At some point with the Ubuntu clients, though, the remote end starts retransmitting the same TCP segment over and over (with the transmit delay increasing between each retransmission). The client sends what looks like a valid TCP ACK to each retransmission, but the remote end still continues to transmit the same TCP segment periodically. This extends ad infinitum and the connection stalls. My question here would be: Does anyone have any recommendations for how to troubleshoot and/or determine the root cause of the TCP issue? It's as if the remote end isn't accepting the ACK messages sent by the VPN client. One common difference between the CentOS node and the various Ubuntu releases is that Ubuntu has a much more recent Linux kernel version (from 3.2 in Ubuntu 12.04 to 3.8 in 13.04). A pointer to some new kernel bug maybe? I'm assuming that if that were so, then I wouldn't be the only one experiencing the problem; I don't think this seems like a particularly exotic setup.

• Error 5 partition table invalid or corrupt

  - by Clodoaldo

  I'm trying to add a second SSD to a Centos 6 system. But I get the Error 5 partition table invalid or corrupt at boot. The system already has a single SSD (sdb) and a pair of HDDs (sd{a,c}) in a RAID 1 array from where it boots. It is as if the new SSD assumes one of the devices of the RAID array. Is it?

• Nagios plugin script not working as expected

  - by Linker3000

  I have modified an off-the-shelf Nagios plugin perl script to (in theory) return a one or zero according to the existence, or not, of a file on a remote linux server. The script runs a remote ssh session and logs in as the nagios user. The remote linux servers have private keys setup for that user, and on the bash command line the script works as expected, but when run as a plugin it always returns '1' (true) even if the file does not exist. Some help with the logic or a comment on why things are not working as expected within Nagios would be appreciated. I'd prefer to use this ssh login method rather than having to install nrpe on all the linux servers. To run from a command line (assuming remote server has a user called nagios with a valid private key): ./check_reboot_required -e ssh -H remote-servers-ip-addr -p 'filename-to-check' -v Ta. #! /usr/bin/perl -w # # # License Information: # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
