  • How to tell if a freebsd jail is up to date?

    - by Martin Torhage
    I've set up a "Service Jail" in FreeBSD 8.0 according to the FreeBSD Handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html). After upgrading the host to the latest patch level and then performed a jail-upgrade, freebsd-fetch still reports that there are files in need of an update in the jail. Is this expected? Then how do I know if a jail is up to date? This is what I've done in more detail: After the initial setup of the jail freebsd-update fetch reported that there were no updates available neither in the host system nor in the jail. This was expected. A while later freebsd-update fetch reported that the following files where in need of an update both in the host and in the jail. /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a I updated the host and followed the upgrade guide for the jail (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html#JAILS-SERVICE-JAILS-UPGRADING). freebsd-update fetch now reports that there are no updates available in the host but the following is the output from freebsd-update fetch in the jail: [root@bb /]# freebsd-update fetch Looking up update.FreeBSD.org mirrors... 3 mirrors found. Fetching metadata signature for 8.0-RELEASE from update5.FreeBSD.org... done. Fetching metadata index... done. Inspecting system... done. Preparing to download files... done. The following files are affected by updates, but no changes have been downloaded because the files have been modified locally: /var/db/mergemaster.mtree The following files will be updated as part of updating to 8.0-RELEASE-p2: /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a Shouldn't freebsd-update know that the jail is up to date or have I failed upgrading it? How am I supposed to know if a jail is up to date if freebsd-update can't tell? I'm sure I ran make cleandir twice before make buildworld. TIA

  • High CPU from httpd process

    - by KHWeb
    I am currently getting high CPU on a server that is just running a couple of sites with very low traffic. One of the sites is in still development going live soon. However, this site is very very slow...When browsing through its pages I can see that the CPU goes from 30% to 100% for httpd (see top output below). I have tuned httpd & MySQL, Apache Solr, Tomcat for high performance, and I am using APC. Not sure what to do from here or how to find the culprit as I have a bunch of messages on the httpd log and have been chasing dead ends for some time...any help is greatly appreciated.

  • Trouble connecting a Ubuntu system to IPv6 tunnel over NAT

    - by John Millikin
    I'm trying to set up an IPv6 tunnel, via Hurricane Electric's tunnel-broker service. I've configured my system using their example commands: # $ipv4a = tunnel server's IPv4 IP # $ipv4b = user's IPv4 IP # $ipv6a = tunnel server's side of point-to-point /64 allocation # $ipv6b = user's side of point-to-point /64 allocation ip tunnel add he-ipv6 mode sit remote $ipv4a local $ipv4b ttl 255 ip link set he-ipv6 up ip addr add $ipv6b dev he-ipv6 ip route add ::/0 dev he-ipv6 And have configured my desktop to be in my NAT router's DMZ. The router is running Tomato firmware. But I can't ping any IPv6 services: $ ping6 -I he-ipv6 '2001:470:1f04:454::1' PING 2001:470:1f04:454::1(2001:470:1f04:454::1) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes From 2001:470:1f04:454::2 icmp_seq=1 Destination unreachable: Address unreachable From 2001:470:1f04:454::2 icmp_seq=2 Destination unreachable: Address unreachable I can ping my local address: $ ping6 -I he-ipv6 '2001:470:1f04:454::2' PING 2001:470:1f04:454::2(2001:470:1f04:454::2) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes 64 bytes from 2001:470:1f04:454::2: icmp_seq=1 ttl=64 time=0.037 ms 64 bytes from 2001:470:1f04:454::2: icmp_seq=2 ttl=64 time=0.039 ms I don't know much about routing, but results I found online suggested the output of ip -6 route and ip addr could be useful: $ ip -6 route 2001:470:1f04:454::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 default dev he-ipv6 metric 1024 mtu 1480 advmss 1420 hoplimit 4294967295 $ ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 100 link/ether 00:1c:c0:a1:98:b2 brd ff:ff:ff:ff:ff:ff inet 192.168.1.10/24 brd 192.168.1.255 scope global eth1 inet6 fe80::21c:c0ff:fea1:98b2/64 scope link valid_lft forever preferred_lft forever 3: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 36:4c:33:ab:0d:c6 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 inet6 fe80::344c:33ff:feab:dc6/64 scope link valid_lft forever preferred_lft forever 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 00:76:62:6e:65:74 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 7e:29:5e:7c:ba:93 brd ff:ff:ff:ff:ff:ff 6: sit0: <NOARP> mtu 1480 qdisc noop state DOWN link/sit 0.0.0.0 brd 0.0.0.0 7: he-ipv6@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN link/sit 24.130.225.239 peer 72.52.104.74 inet6 2001:470:1f04:454::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::1882:e1ef/128 scope link valid_lft forever preferred_lft forever

  • MariaDB doesn't upgrade, 2 versions are installed

    - by zahorak
    I have a server running on Debian wheezy with MaraiDB and OwnCloud. Few days ago, I wanted to update the packages because of the OwnCloud updates but something went wrong. Usually in this case I'd probably try to remove and again install the problematic packages, but on a server which is used by different people it doesn't seem like a valid solution anymore. Here you can see my console output: user@server:~$ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these.

  • VPN IP Routing - slow connections

    - by dannymcc
    UPDATE: Router error logs show: LCP Time-out 0 I'm not sure how to correct this. The Lan-to-Lan profiles are set to -1 Idle Timeout (for the remote branch). I have a PPTP VPN running between two Draytek 2820 routers. They are setup that one dials out to the other one. Main Practice - 192.168.1.0/24 Branch - 192.168.3.0/24 I have then set (on the Branch) router the following route: 192.168.1.0/24 If I then request a server running on 192.168.1.1 from the Branch, it correctly routes through VPN tunnel. If I request the branch server at 192.168.3.1 it correctly routes to the local server without using the VPN tunnel. I have temporarily disabled the firewall on both routers, and made sure that QoS is disabled. The Main Practice internet connection is ~30mb down / ~10mb up, and the Branch connection is ~5mb down / ~2mb up. Anything over the VPN tunnel runs pretty slowly (VNC, Remote Desktop and Terminal Emulators). However, if I dial using the Windows VPN wizard, creating a connection from the laptop to the Main Practice - everything runs quickly. I'm looking for possible causes, and/or ways of further diagnosing the issue. Any help would be greatly appreciated! UPDATE: In summary, when I connect within the Branch and try and access a host that's within the Main Practice it works, but slowly. If I then dial the VPN on my Windows 7 laptop whilst still connected to the Branch network, it's fast.

  • Apache taking up too much CPU

    - by andrewtweber
    I'm trying to manage a server on Amazon for a network of sites that receives about 100 million pageviews per month. Unfortunately, nobody out of my team of 5 developers has much server admin experience. Right now we have the MaxClients set to 1400. Currently our traffic is about average, and we have 1150 total Apache processes running, which use about 2% CPU each! Out of those 1150, 800 of them are currently sleeping, but still taking up CPU. I'm sure there are ways to optimize this. I have a few thoughts: It appears Apache is creating a new process for every single connection. Is this normal? Is there a way to more quickly kill the sleeping processes? Should we turn KeepAlive on? Each page loads about 15-20 medium-sized graphics and a lot of javascript/css. So, here's our Apache setup. We do plan on contracting a server admin asap, but I would really appreciate some advice until we can find someone. Timeout 25 KeepAlive Off MaxKeepAliveRequests 200 KeepAliveTimeout 5 <IfModule prefork.c> StartServers 100 MinSpareServers 20 MaxSpareServers 50 ServerLimit 1400 MaxClients 1400 MaxRequestsPerChild 5000 </IfModule> <IfModule worker.c> StartServers 4 MaxClients 400 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> Full top output: top - 23:44:36 up 1 day, 6:43, 4 users, load average: 379.14, 379.17, 377.22 Tasks: 1153 total, 379 running, 774 sleeping, 0 stopped, 0 zombie Cpu(s): 71.9%us, 26.2%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 1.9%si, 0.0%st Mem: 70343000k total, 23768448k used, 46574552k free, 527376k buffers Swap: 0k total, 0k used, 0k free, 10054596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1756 mysql 20 0 10.2g 1.8g 5256 S 19.8 2.7 904:41.13 mysqld 21515 apache 20 0 396m 18m 4512 R 2.1 0.0 0:34.42 httpd 21524 apache 20 0 396m 18m 4032 R 2.1 0.0 0:32.63 httpd 21544 apache 20 0 394m 16m 4084 R 2.1 0.0 0:36.38 httpd 21643 apache 20 0 396m 18m 4360 R 2.1 0.0 0:34.20 httpd 21817 apache 20 0 396m 17m 4064 R 2.1 0.0 0:38.22 httpd 22134 apache 20 0 395m 17m 4584 R 2.1 0.0 0:35.62 httpd 22211 apache 20 0 397m 18m 4104 R 2.1 0.0 0:29.91 httpd 22267 apache 20 0 396m 18m 4636 R 2.1 0.0 0:35.29 httpd 22334 apache 20 0 397m 18m 4096 R 2.1 0.0 0:34.86 httpd 22549 apache 20 0 395m 17m 4056 R 2.1 0.0 0:31.01 httpd 22612 apache 20 0 397m 19m 4152 R 2.1 0.0 0:34.34 httpd 22721 apache 20 0 396m 18m 4060 R 2.1 0.0 0:32.76 httpd 22932 apache 20 0 396m 17m 4020 R 2.1 0.0 0:37.34 httpd 22933 apache 20 0 396m 18m 4060 R 2.1 0.0 0:34.77 httpd 22949 apache 20 0 396m 18m 4060 R 2.1 0.0 0:34.61 httpd 22956 apache 20 0 402m 24m 4072 R 2.1 0.0 0:41.45 httpd

  • enabling gzip with htaccess...why is it hit or miss?

    - by adam-asdf
    I have shared hosting through Justhost. I use the HTML5 Boilerplate .htaccess (have tried other methods from here and there without luck) the compression part is as follows: <IfModule mod_deflate.c> # Force deflate for mangled headers developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping/ <IfModule mod_setenvif.c> <IfModule mod_headers.c> SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding </IfModule> </IfModule> # Compress all output labeled with one of the following MIME-types <IfModule mod_filter.c> AddOutputFilterByType DEFLATE application/atom+xml \ application/javascript \ application/json \ application/rss+xml \ application/vnd.ms-fontobject \ application/x-font-ttf \ application/xhtml+xml \ application/xml \ font/opentype \ image/svg+xml \ image/x-icon \ text/css \ text/html \ text/plain \ text/x-component \ text/xml </IfModule> </IfModule> However, it isn't working—at least I don't think—My home page (html) isn't compressing, the CSS and some of the JS aren't gzipped. It is failing on HTML, CSS and JS. However, some things are (or were, who knows what it will look like when you check) gzipped. My domain is http://adaminfinitum.com/ What is weird is that the (Google) PageSpeed browser extension for Firefox (whatever the current version is [Nov. 2012]) gives me a 95% speed rating (and no warnings about compression), yet YSlow and Chrome developer tools both flag me about gzip, as does a tool I found on here while researching this. To reduce cookies I set up a subdomain on my site and I thought maybe that was it so I added an .htaccess there also, but no luck. To reduce http requests I embedded some of webfonts and images in CSS (HTML5 BP stipulates not to compress images, and apparently '.woff' files are already compressed) so I thought maybe that was it and I spent all day separating and asynchronously loading those portions (via Modernizr.load) but that hasn't helped either...if anything it made it worse due to increasing http requests (I realize speed scores of async resources may be misleading). Researching this, it seems to be a fairly common issue but I haven't found an explanation/solution. I don't think it is a MIME-type issue, I have quadruple checked (and thrice edited) my .htaccess files. My hosting company said they run Apache 2.2.22 and I have looked at everything I can find. What gives?

  • GRUB 2 freezing at OS selection screen, what could be the cause?

    - by Michael Kjörling
    Mains power is somewhat unreliable where I live, so every now and then, the computer gets rebooted when the PSU can't maintain proper voltage during a brown-out or momentary black-out. It's happened a few times recently that when power is restored, the BIOS POST completes successfully, GRUB starts to load and then freezes. I've seen this at the Welcome to GRUB! message, but it seems to happen more often just past the switch to the graphical OS list. At this point, the computer will not respond to anything (arrow keys, control commands, Ctrl+Alt+Del, ...) - it simply sits there displaying this image, seemingly doing nothing more. At that point, turning the computer off using the power button and letting it sit for a while (cooling down?) has allowed it to boot successfully. Turning the computer off and immediately back on seems to give the same result (successful POST then freeze in GRUB). This behavior began recently, although does not seem to be directly correlated with my hard disk woes (although it may be relevant that GRUB resides on that physical disk, I don't know). Once the computer has booted, it runs without a hitch. I know that a "proper" solution would be to invest in a UPS, but what might be causing behavior like this? I was thinking in terms of perhaps the CPU shutting down as a thermal control measure, but if that was the cause then wouldn't I see similar freezes during use (which I do not)? What else could cause freezes apparently closely but not perfectly related to the BIOS handover from POST to OS bootloader? The BIOS settings are to reset to previous power status after a power loss. Since the PC in question is almost always turned on, this means restore to full power status. I have no expansion cards installed that make any BIOS extensions known by screen output during the boot process, at least, but I do have a few expansion cards installed. Haven't made any changes in that regard in a long time, now. I haven't touched GRUB itself for a long time, whether configuration or binaries, so I don't think that's the problem. Also, it doesn't really make sense that a bug in GRUB would manifest itself only once in a blue moon but significantly more often after a power failure.

  • How to reinstall Mac OS X on OS X/Linux dual-boot system?

    - by strangeronyourtrain
    My setup: I have a MacBook Pro 5,5 with a Mac OS X Snow Leopard partition and a Linux partition. I use rEFIt to boot into Linux. I didn't use Boot Camp when I originally installed Linux; instead, I manually created the partition (with either Disk Utility in OS X or Gparted on a Linux live CD--I don't recall which one) and then installed Linux on it from a live CD. The problem: My OS X partition is corrupt, and I need to reinstall Snow Leopard. Since I installed rEFIt from within OS X, I'm concerned that wiping the OS X partition will prevent me from booting into my Linux partition. How can I do this without losing access to my Linux partition? Is it possible to install Snow Leopard on the partition I reserved for it, or will it automatically overwrite the entire drive? And if I do the fresh OS X install and then install rEFIt again, will it automatically recognize my Linux partition? Thanks for any tips! Specs: MacBook Pro 5,5 (Mid-2009); Snow Leopard 10.6.7/64-bit Sabayon Linux, 2.6.36 kernel EDIT/UPDATE: Thanks, but the situation has taken a more complicated turn: I tried to reinstall Snow Leopard from the DVD, but it refused to install onto my Mac partition, claiming: "The disk cannot be used to start up your computer." Disk Utility wouldn't let me resize the partition or create a new one, and it doesn't see my Linux partition. It only displays the two partitions "Macintosh HD" and Linux Swap. I can, however, see all the partitions from Linux. This is the partition table as shown in Gparted: And the output of "fdisk -l" is: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 409639 204819+ ee GPT /dev/sda2 409640 349590464 174590412+ af HFS / HFS+ /dev/sda3 483122745 488392064 2634660 82 Linux swap / Solaris /dev/sda4 * 349590465 483122744 66766140 83 Linux Partition table entries are not in disk order I wonder if this is because I originally partitioned my disk with Gparted instead of OS X's Disk Utility (at this point, I don't recall whether I used Gparted or Disk Utility). In any case, it doesn't seem safe to do any reformatting with Disk Utility now, as I'm afraid it will wipe sda2 ("Macintosh HD") as well as sda4 (my Linux partition). So... I'm hoping to find a solution that doesn't involve wiping my entire hard disk. Would it be safe/possible to use Gparted to erase sda2 ("Macintosh HD") and then use the Snow Leopard DVD to install OS X onto [I]just[/I] sda2 without touching the other partitions? Thanks for any insight!

  • OSX 10.6.6 SSH md5 break-in check

    - by Alex
    Information Recently one of the linux servers that I access was compromised to steal passwords and ssh keys using a modified ssh binary. This lead me to question if the attacker had compromised my OSX Laptop which had ssh access turned on. A sophos virus scan turned up nothing, and I did not have rkhunter installed before the attack, so I could not compare hashes of the system binaries to be sure. However because OSX is relatively standard for each of their major releases, I asked fiends for md5 hashes md5 /usr/bin/ssh and md5 /usr/sbin/sshd as a basic first check to see if there was anything different about my machine. A few emails later I have found the following data: Version (Arch) [N] MD5 (/usr/bin/ssh) MD5 (/usr/sbin/sshd) OSX 10.5.8 (PPC) [3] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.5.8 (intel) [5] 1e9fd483eef23464ec61c815f7984d61 9d32a36294565368728c18de466e69f1 OSX 10.6.x (intel) [7] 591fbe723011c17b6ce41c537353b059 e781fad4fc86cf652f6df22106e0bf0e OSX 10.6.x (intel) [4] 58be068ad5e575c303ec348a1c71d48b 33dafd419194b04a558c8404b484f650 Mine 10.6.6 (intel) df344cc00a294c91230c65e8b7332a79 b5094ccf4cd074aaf573d4f5df75906a where N is the number of machines with with that MD5, and the last row is my laptop. The sample is relatively heterogeneous spaning a few years of different makes and models of Apples, and different versions of 10.6.x. The different hash for my system made me worried that these binaries might have been compromised. So I made sure that my backup for the week was good, and dived into formatting my system and reinstalling OSX. After reinstalling OSX from the manufacturer DVD, I found that the MD5 hash did not change for either ssh, or sshd. Goal Make sure that my system is does not have any malicious software. Should I be worried that this base install of OSX (with no other software installed) has been compromised? I have also updated my system to 10.6.6 and found no change as well. Other Information I am not sure if this is helpful information, but my laptop is a i7 15 inch MacBook Pro bought in Nov 2010, and here is some output from system_profiler: System Software Overview: System Version: Mac OS X 10.6.6 (10J567) Kernel Version: Darwin 10.6.0 64-bit Kernel and Extensions: No Time since boot: 1:37 Hardware: Hardware Overview: Model Name: MacBook Model Identifier: MacBook6,2 Processor Name: Intel Core i7 Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 4 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s Boot ROM Version: MBP61.0057.B0C SMC Version (system): 1.58f16 Sudden Motion Sensor: State: Enabled On the laptop, I find: $ codesign -vvv /usr/bin/ssh /usr/bin/ssh: valid on disk /usr/bin/ssh: satisfies its Designated Requirement $ codesign -vvv /usr/sbin/sshd /usr/sbin/sshd: valid on disk /usr/sbin/sshd: satisfies its Designated Requirement $ ls -la /usr/bin/ssh -rwxr-xr-x 1 root wheel 1001520 Feb 11 2010 /usr/bin/ssh $ ls -la /usr/sbin/sshd -rwxr-xr-x 1 root wheel 1304800 Feb 11 2010 /usr/sbin/sshd $ ls -la /sbin/md5 -r-xr-xr-x 1 root wheel 65232 May 18 2009 /sbin/md5 Update So far I have not gotten an answer about this question, but if you could help by increasing the number of hashes that I can compare against, that would be great. To get hashes, and version numbers, run the following on osx: md5 /usr/bin/ssh md5 /usr/sbin/sshd ssh -V sw_vers

  • Excel on Mac Mini OS X Version 10.7.2 - Create text file named after a cell containing other cell data from other cells

    - by user143041
    I tried using the code below for the Excel program on my `Mac Mini using the OS X Version 10.7.2 and it keeps saying Error due to file name / path: (The Excel fiel I am creating is going to be a template with my formulas and macros installed which will be used over and over). Sub CreateFile() Do While Not IsEmpty(ActiveCell.Offset(0, 1)) MyFile = ActiveCell.Value & ".txt" fnum = FreeFile() Open MyFile For Output As fnum Print #fnum, ActiveCell.Offset(0, 1) & " " & ActiveCell.Offset(0, 2) Close #fnum ActiveCell.Offset(1, 0).Select Loop End Sub What Im trying to do: 1st Objective I would like to have the following data to be used to create a text file. A:A is what I need the name of the file to be. B:2 is the content I need in the text file. So, A2 - "repair-video-game-Glassboro-NJ-08028.txt" is the file name and B2 to be the content in the file. Next, A3 is the file name and B3 is the content for the file, etc. ONCE the content reads what is in cell A16 and B16 (length will vary), the file creation should stop, if not then I can delete the additional files created. This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? 2nd Objective I would like to have the following data to be used to create a text file. A:1 is what I need the name of the file to be. B:B is the content I want in the file. So, A2 - is the file name "geo-sitemap.xml" and B:B to be the content in the file (ignore the .xml file extension in the photo). ONCE the content cell reads what is in cell "B16" (length will vary), the file creation should stop, if not then I can adjust the cells that have need content (formulated content you see in the image is preset for 500 rows). This sheet will never change. Is there a way to establish the excel macro to always go to this sheet instead of have to select it with the mouse to identify the starting point? I can Provide the content in the cells that are filled in by excel formulas that are not not to be included in the .txt files. It is ok if it is not possible. I can delete the extra cells that are not populated (based on the data sheet). Please let me know if you need any more additional information or clarity and I will be happy to provide it. I really appreciate your help! Thank you

  • Unable to ping local machines by name in Windows 7

    - by aardvarkk
    I'm having a strange (and persistent!) problem with pinging local machines on my network by name. I believe my machine (Windows 7 64-bit) is the only one having this issue. This is over a wireless connection. As an example, consider a device on my network by the name of WDTVLiveHub. It's a Western Digital Live Hub (surprise!). If I go to my router's DHCP Client Table in the browser (my router is a WRT400N), I see this entry: WDTVLiveHub 192.168.1.101 Great. So I try to ping that IP address: ping 192.168.1.101 Pinging 192.168.1.101 with 32 bytes of data: Reply from 192.168.1.101: bytes=32 time=9ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Reply from 192.168.1.101: bytes=32 time=16ms TTL=64 Ping statistics for 192.168.1.101: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 9ms, Maximum = 16ms, Average = 14ms OK, still looking good. Now I try to ping it by name: ping WDTVLiveHub Ping request could not find host WDTVLiveHub. Please check the name and try again. From what I've read, this implies a problem with DNS servers and host name lookups. Interestingly, if I type the following: pathping 192.168.1.101 I get this output: Tracing route to WDTVLIVEHUB [192.168.1.101] over a maximum of 30 hops: 0 Scotty [192.168.1.103] 1 WDTVLIVEHUB [192.168.1.101] Computing statistics for 25 seconds...

The biggest problem is that my mapped network drives have to be done by IP, and then any time the router assigns new IP addresses to those devices, all of my network shares break again. Stinks! Would love some assistance on possible solutions. I've tried all of this netsh catalog resetting and that didn't seem to fix anything at all. Would love an explanation of what's going wrong, too, rather than blindly resetting things! Thanks!

  • Logrotate not doing any rotation

    - by blizz
    I just set up LogRotate on my RHEL6 server so that it rotates my custom Apache log files. However, it doesn't do anything when i try manually running it. I expect it to rotate the log files "access.log" and "err.log". They have been there for a few days and need to be rotated. Here is the output: [root@pc1 httpd]# logrotate -d -f /etc/logrotate.d/apache reading config file /etc/logrotate.d/apache reading config info for /var/log/httpd/*log /var/www/html/NSLogs/access.log /var/www/html/NSErrorLogs/err.log Handling 1 logs rotating pattern: /var/log/httpd/*log /var/www/html/NSLogs/access.log /var/www/html/NSErrorLogs/err.log forced from command line (no old logs will be kept) empty log files are rotated, old logs are removed considering log /var/log/httpd/access_log log needs rotating considering log /var/log/httpd/error_log log needs rotating considering log /var/www/html/NSLogs/access.log log needs rotating considering log /var/www/html/NSErrorLogs/err.log log needs rotating rotating log /var/log/httpd/access_log, log->rotateCount is 0 dateext suffix '-20131023' glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' glob finding old rotated logs failed fscreate context set to unconfined_u:object_r:httpd_log_t:s0 renaming /var/log/httpd/access_log to /var/log/httpd/access_log-20131023 disposeName will be /var/log/httpd/access_log-20131023.gz running postrotate script running script with arg /var/log/httpd/access_log: " /usr/bin/killall -HUP httpd " compressing log with: /bin/gzip removing old log /var/log/httpd/access_log-20131023.gz error: error opening /var/log/httpd/access_log-20131023.gz: No such file or directory rotating log /var/log/httpd/error_log, log->rotateCount is 0 dateext suffix '-20131023' glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' glob finding old rotated logs failed fscreate context set to unconfined_u:object_r:httpd_log_t:s0 renaming /var/log/httpd/error_log to /var/log/httpd/error_log-20131023 disposeName will be /var/log/httpd/error_log-20131023.gz running postrotate script running script with arg /var/log/httpd/error_log: " /usr/bin/killall -HUP httpd " compressing log with: /bin/gzip removing old log /var/log/httpd/error_log-20131023.gz error: error opening /var/log/httpd/error_log-20131023.gz: No such file or directory rotating log /var/www/html/NSLogs/access.log, log->rotateCount is 0 dateext suffix '-20131023' glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' glob finding old rotated logs failed fscreate context set to unconfined_u:object_r:httpd_sys_rw_content_t:s0 renaming /var/www/html/NSLogs/access.log to /var/www/html/NSLogs/access.log-20131023 disposeName will be /var/www/html/NSLogs/access.log-20131023.gz running postrotate script running script with arg /var/www/html/NSLogs/access.log: " /usr/bin/killall -HUP httpd " compressing log with: /bin/gzip removing old log /var/www/html/NSLogs/access.log-20131023.gz error: error opening /var/www/html/NSLogs/access.log-20131023.gz: No such file or directory rotating log /var/www/html/NSErrorLogs/err.log, log->rotateCount is 0 dateext suffix '-20131023' glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]' glob finding old rotated logs failed fscreate context set to unconfined_u:object_r:httpd_sys_rw_content_t:s0 renaming /var/www/html/NSErrorLogs/err.log to /var/www/html/NSErrorLogs/err.log-20131023 disposeName will be /var/www/html/NSErrorLogs/err.log-20131023.gz running postrotate script running script with arg /var/www/html/NSErrorLogs/err.log: " /usr/bin/killall -HUP httpd " compressing log with: /bin/gzip removing old log /var/www/html/NSErrorLogs/err.log-20131023.gz error: error opening /var/www/html/NSErrorLogs/err.log-20131023.gz: No such file or directory

  • getfacl command and Linux file permissions - getting 403 error when accessing Wordpress

    - by tommytwoeyes
    I'm configuring Wordpress for a friend, and I just screwed up the Wordpress directory permissions (I suspect) using setfacl. Webfaction doesn't allow sudo or allow me to change the directory group ownership using chown. Now it appears that something I did is causing the entire application to give me 403 errors when I try to access it. The current directory listing looks like this (I set the whole thing to 777 temporarily to try to recover access to it): drwxrwsr-x+ 6 myusername myusername 4096 Mar 2 07:07 ./ drwxr-xr-x 3 root root 4096 Feb 25 19:48 ../ -rwxrwxr-x+ 1 myusername myusername 286 Mar 2 06:33 gzip.php -rwxrwxr-x+ 1 myusername myusername 4831 Mar 4 20:02 .htaccess -rwxrwxr-x+ 1 myusername myusername 397 Feb 25 19:49 index.php -rw-rw-r--+ 1 myusername myusername 15606 Feb 25 19:49 license.txt -rw-rw-r--+ 1 myusername myusername 9200 Feb 25 19:49 readme.html drwxrwsr-x+ 6 myusername myusername 4096 Feb 25 19:49 .svn/ -rwxrwxr-x+ 1 myusername myusername 4337 Feb 25 19:49 wp-activate.php drwxr-xr-x+ 10 myusername myusername 4096 Mar 4 20:03 wp-admin/ -rwxrwxr-x+ 1 myusername myusername 40283 Feb 25 19:49 wp-app.php -rwxrwxr-x+ 1 myusername myusername 226 Feb 25 19:49 wp-atom.php -rwxrwxr-x+ 1 myusername myusername 274 Feb 25 19:49 wp-blog-header.php -rwxrwxr-x+ 1 myusername myusername 3931 Feb 25 19:49 wp-comments-post.php -rwxrwxr-x+ 1 myusername myusername 244 Feb 25 19:49 wp-commentsrss2.php -rwxrwxr-x+ 1 myusername myusername 3485 Feb 25 20:15 wp-config.php drwxr-xr-x+ 6 myusername myusername 4096 Feb 26 08:52 wp-content/ -rwxrwxr-x+ 1 myusername myusername 1255 Feb 25 19:49 wp-cron.php -rwxrwxr-x+ 1 myusername myusername 246 Feb 25 19:49 wp-feed.php drwxrwxr-x+ 9 myusername myusername 4096 Feb 25 19:49 wp-includes/ -rwxrwxr-x+ 1 myusername myusername 1997 Feb 25 19:49 wp-links-opml.php -rwxrwxr-x+ 1 myusername myusername 2453 Feb 25 19:49 wp-load.php -rwxrwxr-x+ 1 myusername myusername 27787 Feb 25 19:49 wp-login.php -rwxrwxr-x+ 1 myusername myusername 7774 Feb 25 19:49 wp-mail.php -rwxrwxr-x+ 1 myusername myusername 494 Feb 25 19:49 wp-pass.php -rwxrwxr-x+ 1 myusername myusername 224 Feb 25 19:49 wp-rdf.php -rwxrwxr-x+ 1 myusername myusername 334 Feb 25 19:49 wp-register.php -rwxrwxr-x+ 1 myusername myusername 226 Feb 25 19:49 wp-rss2.php -rwxrwxr-x+ 1 myusername myusername 224 Feb 25 19:49 wp-rss.php -rwxrwxr-x+ 1 myusername myusername 9655 Feb 25 19:49 wp-settings.php -rwxrwxr-x+ 1 myusername myusername 18644 Feb 25 19:49 wp-signup.php -rwxrwxr-x+ 1 myusername myusername 3702 Feb 25 19:49 wp-trackback.php -rwxrwxr-x+ 1 myusername myusername 3210 Feb 25 19:49 xmlrpc.php The getfacl output looks like this: # file: . # owner: myusername # group: myusername user::rwx group::r-x group:apache:rw- mask::rwx other::r-x I simply wanted to change the ownership to myusername:apache and the file permissions to 755.

  • Old operational master still thinks it is the "one"

    - by Doug
    Hi there, I have a domain with 3 AD servers for now i'll just call them: AD01 (Win 2008 GC, Operations master) AD02 (Win 2008 GC) AD03 (Win 2003 GC) A couple of months there was some hardware issues with AD01 so the operations master, PDC and Infrastructure Master was moved to AD02. All machines where on while this was happening. AD01 (Win 2008 GC) AD02 (Win 2008 GC, Operations master) AD03 (Win 2003 GC) AD01 was then shutdown for a month. Upon starting this machine up with replaced hardware (NIC and RAID card) i now have a weird problem. AD01 Thinks it is operations master still in AD on the local box AD02 & AD03 Thinks AD02 is operations master in AD on both boxes When running DCDIAG on AD01 i get a number of issues (listed below) When running "dcdiag /test:advertising" on AD01: Doing primary tests Testing server: Default-First-Site-Name\AD01 Starting test: Advertising Warning: DsGetDcName returned information for \\ad02.domain.local, when we were trying to reach AD01. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... AD01 failed test Advertising Running partition tests on : ForestDnsZones Running partition tests on : DomainDnsZones Running partition tests on : Schema Running partition tests on : Configuration Running partition tests on : domain Running enterprise tests on : domain.local When running "dcdiag" on AD01 i get the following errors (excerpt of the Final output): Testing server: Default-First-Site-Name\AD01 Starting test: Advertising Warning: DsGetDcName returned information for \\ad02.domain.local, when we were trying to reach AD01. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... AD01 failed test Advertising Starting test: FrsEvent There are warning or error events within the last 24 hours after the SYSVOL has been shared. Failing SYSVOL replication problems may cause Group Policy problems. Starting test: NCSecDesc Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have Replicating Directory Changes In Filtered Set access rights for the naming context: DC=ForestDnsZones,DC=domain,DC=local Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have Replicating Directory Changes In Filtered Set access rights for the naming context: DC=DomainDnsZones,DC=domain,DC=local Starting test: Replications [Replications Check,Replications Check] Inbound replication is disabled. To correct, run "repadmin /options AD01 -DISABLE_INBOUND_REPL" [Replications Check,AD01] Outbound replication is disabled. To correct, run "repadmin /options AD01 -DISABLE_OUTBOUND_REPL" So the problem appeasr to be that when i moved the operations master, AD01 never got the memo, and now that it's started up, all the other AD servers don't think its the boss anymore when it trys to replicate etc. So i really need to manually update AD01 so that it knows who the operations master, instrastructure and PDC is - but i'm not having any luck I've been googling for nearly a day and all solutions lead to "the cake is a lie" Your ninja skills will be greatly appreciated

  • Determining the health of a Cisco switch port?

    - by ewwhite
    I've been chasing a packet-loss and network stability issue for a handful of end-users on an internal network for the past few days... These issues surfaced recently, however, the location was struck by lightning six weeks ago. I was seeing 5-10% packet loss between a stack of four Cisco 2960's and several PC's and phones on the other side of a 77-meter run. The PC's were run inline with the phones over a trunked link. We were seeing dropped calls and interruptions in client-server applications and Microsoft Exchange connectivity. I tried the usual troubleshooting steps remotely, having a local technician do the following during breaks in user and production activity: change cables between the wall jack and device. change patch cables between the patch panel and switch port(s). try different switch ports within the 2960 stack. change end-user devices with known-good equipment (new phones, different PC's). clear switch port interface counters and monitor incrementing errors closely. (Pastebin output of sh int) Pored over the device logs and Observium RRD graphs. No link up/down issues from the switch side. change power strips on the end-user side. test cable runs from the Cisco 2960 using test cable-diagnostics tdr int Gi4/0/9 (clean)* test cable runs with a Tripp-Lite cable tester. (clean) run diagnostics on the switch stack members. (clean) In the end, it took three changes of switch ports to find a stable solution. The only logical conclusion is that a few Cisco 2960 switch ports are bad or flaky... Not dead, but not consistent in behavior either. I'm not used to seeing individual ports die in this manner. What else can I test or check to determine if these devices are bad? Is it common for single ports to have problems, rather than a contiguous bank of ports? BTW - show cable-diagnostics tdr int Gi4/0/14 is very cool... Interface Speed Local pair Pair length Remote pair Pair status --------- ----- ---------- ------------------ ----------- -------------------- Gi4/0/14 1000M Pair A 79 +/- 0 meters Pair B Normal Pair B 75 +/- 0 meters Pair A Normal Pair C 77 +/- 0 meters Pair D Normal Pair D 79 +/- 0 meters Pair C Normal

  • freebsd-update reports an upgraded jail as not upgraded

    - by Martin Torhage
    I've set up a "Service Jail" in FreeBSD 8.0 according to the FreeBSD Handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html). After upgrading the host to the latest patch level and then performed a jail-upgrade, freebsd-fetch still reports that there are files in need of an update in the jail. Is this expected? Then how do I know if a jail is up to date? This is what I've done in more detail: After the initial setup of the jail freebsd-update fetch reported that there were no updates available neither in the host system nor in the jail. This was expected. A while later freebsd-update fetch reported that the following files where in need of an update both in the host and in the jail. /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a I updated the host and followed the upgrade guide for the jail (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-application.html#JAILS-SERVICE-JAILS-UPGRADING). freebsd-update fetch now reports that there are no updates available in the host but the following is the output from freebsd-update fetch in the jail: [root@bb /]# freebsd-update fetch Looking up update.FreeBSD.org mirrors... 3 mirrors found. Fetching metadata signature for 8.0-RELEASE from update5.FreeBSD.org... done. Fetching metadata index... done. Inspecting system... done. Preparing to download files... done. The following files are affected by updates, but no changes have been downloaded because the files have been modified locally: /var/db/mergemaster.mtree The following files will be updated as part of updating to 8.0-RELEASE-p2: /usr/lib/libssl.a /usr/lib/libssl_p.a /usr/lib/libzpool.a /usr/lib32/libssl.a /usr/lib32/libssl_p.a /usr/lib32/libzpool.a Shouldn't freebsd-update know that the jail is up to date or have I failed upgrading it? How am I supposed to know if a jail is up to date if freebsd-update can't tell? I'm sure I ran make cleandir twice before make buildworld. TIA

  • Supervisord appears to be running, but monitored programs aren't launched

    - by Brad Montgomery
    I've got supervisord 3.0a8 installed from the system package on ubuntu 10.04 (64bit). The supervisor service appears to be running, but it's not launching the configured programs. Interestingly enough, this exact configuration is running on another system, and is working as expected. The main config file looks like this: ; /etc/supervisor/supervisord.conf [unix_http_server] chmod=0700 file=/var/run/supervisor.sock [supervisord] logfile=/var/log/supervisor/supervisord.log childlogdir=/var/log/supervisor pidfile=/var/run/supervisord.pid [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface [supervisorctl] serverurl=unix:///var/run/supervisor.sock [include] files = /etc/supervisor/conf.d/*.conf A sample program config looks like this: ; /etc/supervisor/conf.d/sample.conf [program:sample] directory=/opt/sample command=/opt/sample/run.sh Where, the /opt/sample/run.sh is: #!/bin/bash while true; do T=`date` echo "[$T] Running!" >> /var/log/sample.log sleep 1 done And, here's some additional information regarding the running instance of supervisord: root@myhost:~# supervisorctl version 3.0a8 root@myhost:~# which supervisorctl /usr/bin/supervisorctl root@myhost:~# which supervisord /usr/bin/supervisord root@myhost:~# supervisorctl status # NOTE that there's no output! root@myhost:~# supervisorctl avail root@myhost:~# service supervisor status is running root@myhost:~# ps aux | grep supervisor root 21740 0.1 0.4 40772 10056 ?

  • Forwarding udp ports iptables packets "lost"?

    - by Dindihi
    I have a Linux router (Debian 6.x) where i forward some ports to internal services. Some tcp ports (like 80, 22...) are OK. I have one Application listening on port 54277udp. No return is coming from this app, i only get Data on this port. Router: cat /proc/sys/net/ipv4/conf/all/rp_filter = 1 cat /proc/sys/net/ipv4/conf/eth0/forwarding = 1 cat /proc/sys/net/ipv4/conf/ppp0/forwarding = 1 $IPTABLES -t nat -I PREROUTING -p udp -i ppp0 --dport 54277 -j DNAT --to-destination $SRV_IP:54277 $IPTABLES -I FORWARD -p udp -d $SRV_IP --dport 54277 -j ACCEPT Also MASQUERADING internal traffic to ppp0(internet) is active & working. Default Policy INPUT&OUTPUT&FORWARD is DROP What is strange, when i do: tcpdump -p -vvvv -i ppp0 port 54277 I get a lot of traffic: 18:35:43.646133 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 18:35:43.652301 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 18:35:43.653324 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 18:35:43.655795 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 18:35:43.656727 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 18:35:43.659719 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 57) source.ip > own.external.ip..54277: [udp sum ok] UDP, length 29 tcpdump -p -i eth0 port 54277 (on the same machine, the router) i get much less traffic. also on the destination $SRV_IP there are only a few packets coming in, but not all. INTERNAL SERVER: 19:15:30.039663 IP source.ip.52394 > 192.168.215.4.54277: UDP, length 16 19:15:30.276112 IP source.ip.52394 > 192.168.215.4.54277: UDP, length 16 19:15:30.726048 IP source.ip.52394 > 192.168.215.4.54277: UDP, length 16 So some udp ports are "ignored/dropped" ? Any idea what could be wrong? Edit: This is strange: The Forward rule has data packets, but the PREROUTING rule has 0 packets... iptables -nvL -t filter |grep 54277 Chain FORWARD (policy DROP 0 packets, 0 bytes) 168 8401 ACCEPT udp -- * * 0.0.0.0/0 192.168.215.4 state NEW,RELATED,ESTABLISHED udp dpt:54277 iptables -nvL -t nat |grep 54277 Chain PREROUTING (policy ACCEPT 405 packets, 24360 bytes) 0 0 DNAT udp -- ppp0 * 0.0.0.0/0 my.external.ip udp dpt:54277 state NEW,RELATED,ESTABLISHED to:192.168.215.4
