  • SQL Server Log File Size Management

    - by Rob
    I have all my databases in full recovery and have the log backups happening every 15 minutes so my log files are usually pretty small. question is if there is a nightly operation that causes lots of transactions to happen and causes my log files to grow, should i shrink them back down afterward? Does having a gigantic log file negatively affect the database performance? Disk space isn't an issue at this time.

  • Using multiple accounts on Gmail on a Blackberry

    - by Andrew G. Johnson
    I love the whole "one inbox" concept on my blackberry. Facebook updates, SMS/MMS messages, and email all lands in the same list. Problem is they assume I have a simple Gmail account without multiple accounts. I have my Gmail account setup to receive email from ~15 different accounts. I assume a lot of tech people do something like this. How have you gotten around in?

  • Availability of downloadable DNSBL dumps?

    - by mtah
    I need to cross-reference data involving a large number of IP addresses against known public proxies, spam-listed IPs etc. For obvious performance and network load reasons, obtaining a regularly updated dump for off-line processing would be preferrable. I currently use http://www.dnsbl.manitu.net/download/nixspam-ip.dump.gz - a digest of ix.dnsbl.manitu.net with 40,000 entries updated every 15 minutes. I'd like something more substantial though, so my question is: does such a thing exist?

  • how to diagnosis and resolve: /usr/lib64/libz.so.1: no version information available

    - by matchew
    I had a hell of a time installing lxml for python2.7 on centOs5.6. For some background, python2.7 is an alternative installation of python on centOS5.6 which comes with python2.4 installed. it was bulit from source per its instrucitons ./configure make make altinstall However, after about 20 hours of trying I managed to find a workable solution and was able to install lxml. Until, I notice the following error at the top of the interpreter: python2.7: /usr/lib64/libz.so.1: no version information available (required by python2.7) Python 2.7.2 (default, Jun 30 2011, 18:55:26) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> print 'Sheeeeut!' this error is printed out everytime I run a script. For example: $ ./test.py /usr/local/bin/python2.7: /usr/lib64/libz.so.1: no version information available (required by /usr/local/bin/python2.7) the script runs flawlessly, but this error is bothersome. After some digging I have seem to believe I have a wrong version of libz installed, that it is either an older version or built for a different platform. I'm not quite sure how, I've only installed libz through yum, as far as I know. Although, I can't quite remember every little thing I tried in my twenty hours of trying. You may also be intereted in what my lib64 folder looks like, here is some information $ ls -ltrh libz* -rwxr-xr-x 1 root root 84K Jan 9 2007 libz.so.1.2.3 -rwxr-xr-x 1 root root 107K Jan 9 2007 libz.a -rwxr-xr-x 1 root root 154K Feb 22 23:30 libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Apr 20 20:46 libz.so.1 -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jun 30 18:43 libzdb.so.7 -> libzdb.so.7.0.2 lrwxrwxrwx 1 root root 13 Jul 1 11:35 libz.so -> libz.so.1.2.3 lrwxrwxrwx 1 root root 15 Jul 1 11:35 libzdb.so -> libzdb.so.7.0.2 notice: the items that Say Jul 1st or Jun 30th are from me. I had initially moved these files into a backup folder as they seeemed to be 1. duplicates and 2. had a date after/during my problems I alluded to earlier that I had with lxml One inclination is to completely remove python2.7 and re-install. I think having it install to /usr/local/ was a poor default choice. However, without the make uninstall option being present it seems to be a time consuming task for a solution I am not quite sure would solve my problem.

  • ftp connection problem, vsftp server, active mode

    - by Mark Szente
    I have a server that runs vsftpd to handle ftp connections. One of my users have a notebook with Total Commander and WinSCP installed. Both ftp clients fail right after the connection is established to the server and it tries to download the directory listing without any particular error message. The weird thing is: the notebook works perfectly ok with other ftp servers. My ftp server also works well with other clients. In fact, this user also has a pc running on the same LAN as the notebook and the pc works well with the ftp server. We use active ftp connection mode. Passive mode works well but is not an option at this point. I would post more technical details but I don't even know what this problem is related to. Anyway, below is the server side tcpdump for the failed connection attempt. There's no further communication between the client and the server after the last line of log. Thank you very much for any hint! 23:39:24.514852 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: S 1314489715:1314489715(0) win 65535 <mss 1460,nop,wscale 3,nop,nop,sackOK> 23:39:24.514896 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: S 2633658883:2633658883(0) ack 1314489716 win 5840 <mss 1460,nop,nop,sackOK,nop,wscale 2> 23:39:24.520842 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 1 win 62500 23:39:24.523803 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 1:21(20) ack 1 win 1460 23:39:24.546858 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 1:15(14) ack 21 win 62497 23:39:24.546902 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 15 win 1460 23:39:24.547247 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 21:55(34) ack 15 win 1460 23:39:24.762806 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 55 win 62493 23:39:30.415011 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 15:28(13) ack 55 win 62493 23:39:30.454116 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 28 win 1460 23:39:31.036283 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 55:78(23) ack 28 win 1460 23:39:31.053018 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 28:34(6) ack 78 win 62490 23:39:31.053042 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 34 win 1460 23:39:31.053268 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 78:97(19) ack 34 win 1460 23:39:31.068969 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 34:40(6) ack 97 win 62488 23:39:31.069148 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 97:112(15) ack 40 win 1460 23:39:31.069179 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 112:119(7) ack 40 win 1460 23:39:31.076981 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 119 win 62485 23:39:31.077010 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 119:177(58) ack 40 win 1460 23:39:31.114979 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 40:45(5) ack 177 win 62478 23:39:31.115164 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 177:186(9) ack 45 win 1460 23:39:31.180966 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 45:53(8) ack 186 win 62476 23:39:31.181066 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 186:216(30) ack 53 win 1460 23:39:31.213065 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 53:80(27) ack 216 win 62473 23:39:31.213180 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 216:267(51) ack 80 win 1460 23:39:31.251086 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 80:86(6) ack 267 win 62466 23:39:31.251498 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054371220 0,nop,wscale 2> 23:39:31.290979 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 86 win 1460 23:39:34.251489 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054374220 0,nop,wscale 2> 23:39:40.249625 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054380220 0,nop,wscale 2> 23:39:43.695108 IP 195.70.xx.xx.21 > 62.201.xx.xx.1057: P 2280716551:2280716588(37) ack 3838413728 win 5840 23:39:52.248791 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054392220 0,nop,wscale 2> 23:40:16.245159 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054416221 0,nop,wscale 2> 23:40:29.853685 IP 195.70.xx.xx.21 > 62.201.xx.xx.1057: FP 37:51(14) ack 1 win 5840 23:40:31.241951 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 267:304(37) ack 86 win 1460 23:40:31.381708 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 304 win 62462

  • Full disk encryption on dual boot system using TrueCrypt

    - by Anders Hovgaard
    I'm thinking about encrypting my whole harddrive for example using TrueCrypt, which I've used for encrypting file containers for a while. It is possible to encrypt the whole harddisk through the program and then add a password secured bootloader before the actual bootloader. Is it possible to do this on a dualboot system with Windows 7 and Fedora 15 currently using Grub as the main bootloader? If so, is it possible to reinstall a system later or will that ruin the whole setup? Thanks

  • Migrating from register.com webmail

    Anyone know of any tools to migrate emails from register.com's webmail to anything else (gmail, local mbox, anything!), I have nearly 15 years of mails and folders I want to keep. Other than spending ages writing some Perl scraper code I wondered if anyone else had already done this. sorry - It's impossible to search Google for the name of a registrar!

  • memcached and PHP ... massive lag with sessions

    - by Ben Dauphinee
    I'm working on a new server built with Unbuntu 10.04, running php-fastcgi, nginx, and memcached. phpinfo() script loads and works great, same as a test memcached script. For any script using sessions, page load time rockets through the roof. --- memcached.ini --- extension=memcached.so memcache.hash_strategy = "consistent" memcache.max_failover_attempts = 100 memcache.allow_failover = 1 session.save_handler = memcached session.save_path = "tcp://127.0.0.1:11211?persistent=1&weight=1&timeout=1&retry_interval=15" Let me know if you need to see any other configs.

  • 64-bit linux kernel only seeing 3 of 4GB after upgrade...

    - by Blaine
    Hey everyone. I am running Ubuntu 9.04 64-bit on my macbook. I had 2GB of ram before, and everything ran great. I just upgraded to 2x2GB (4GB), but my system only sees 3GB of it. OS X, which I am dual booting, sees all 4GB. Also, my video performance is incredibly lacking. Before the upgrade my compiz benchmark was full at 80fps, and now it is at 22fps with very choppy window dragging. Has anyone ever heard of this on a 64-bit kernel? I just don't quite understand what could be the issue. 10$ uname -a Linux macbook 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009 x86_64 GNU/Linux $ free -m total used free shared buffers cached Mem: 2953 1031 1921 0 114 427 -/+ buffers/cache: 489 2463 Swap: 7812 0 7812 9$ lsmod Module Size Used by i915 77960 2 drm 123232 3 i915 binfmt_misc 18572 1 ppdev 16904 0 btusb 21784 2 bridge 63776 0 stp 11140 1 bridge bnep 22912 2 vboxnetadp 109356 0 vboxnetflt 116972 0 vboxdrv 1721612 1 vboxnetflt uvcvideo 69640 0 compat_ioctl32 18304 1 uvcvideo videodev 45184 2 uvcvideo,compat_ioctl32 v4l1_compat 23940 2 uvcvideo,videodev lp 19588 0 parport 49584 2 ppdev,lp snd_hda_intel 557492 3 snd_pcm_oss 52352 0 snd_mixer_oss 24960 1 snd_pcm_oss snd_pcm 99464 2 snd_hda_intel,snd_pcm_oss arc4 10240 2 snd_seq_dummy 11524 0 ecb 11392 2 snd_seq_oss 41984 0 snd_seq_midi 15744 0 snd_rawmidi 33920 1 snd_seq_midi snd_seq_midi_event 16512 2 snd_seq_oss,snd_seq_midi snd_seq 66272 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event ath9k 310584 0 snd_timer 34064 2 snd_pcm,snd_seq snd_seq_device 16276 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq mac80211 251528 1 ath9k iTCO_wdt 21712 0 iTCO_vendor_support 12420 1 iTCO_wdt joydev 20992 0 video 29204 0 snd 78920 15 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device applesmc 37700 0 output 11648 1 video soundcore 16800 1 snd pcspkr 11136 0 cfg80211 43680 1 mac80211 appletouch 19972 0 isight_firmware 11520 0 input_polldev 12688 1 applesmc intel_agp 39408 1 snd_page_alloc 18704 2 snd_hda_intel,snd_pcm led_class 13064 2 ath9k,applesmc hid_apple 15872 0 usbhid 47040 0 ohci1394 42164 0 ieee1394 108288 1 ohci1394 sky2 63364 0 fbcon 49792 0 tileblit 11264 1 fbcon font 17024 1 fbcon bitblit 14464 1 fbcon softcursor 10368 1 bitblit Some information from dmesg: [ 795.820163] ACPI: EC: GPE storm detected, transactions will use polling mode [ 1762.709516] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 1763.078130] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 2362.760889] [drm:i915_getparam] *ERROR* Unknown parameter 6 [ 2416.352084] ACPI: EC: missing confirmations, switch off interrupt mode.

    Using trac, I'm getting a response with the following header: Cache-control: must-revalidate Moreover, no 'Expires' header is being sent. Our local proxy, however, is caching these responses, so when an edit is made, pages need to be 'hard refreshed' to update. Is the proxy misbehaving? Other headers that might be relevant: Connection Keep-Alive Proxy-Connection Keep-Alive Keep-Alive timeout=15, max=100

  • How can I troubleshoot Virtualbox port forwarding from Windows guest to OSX host not working?

    - by joe larson
    There are a plethora of questions about virtual box port forwarding problems but none with my specific details. I have a Windows install living in Virtual Box, hosted within OSX. I've got several webservers running on localhost on different ports within the Windows install. I cannot for the life of me get port forwarding to work so I can access those webservers from OSX. My settings look like this (yes I have a NAT adapter): And in my vbox configuration file the relavent portion looks like this: <NAT> <DNS pass-domain="true" use-proxy="false" use-host-resolver="false"/> <Alias logging="false" proxy-only="false" use-same-ports="false"/> <Forwarding name="RLPWeb" proto="1" hostport="7084" guestip="127.0.0.1" guestport="7084"/> <Forwarding name="UtilWeb" proto="1" hostport="4040" guestip="127.0.0.1" guestport="4040"/> <Forwarding name="WCARLP" proto="1" hostport="8084" guestip="127.0.0.1" guestport="8084"/> <Forwarding name="WCAUtil" proto="1" hostport="4848" guestip="127.0.0.1" guestport="4848"/> </NAT> I've turned off the Windows firewall to ensure it is not interfering, and I am not running a firewall on OSX. Anyway, when I attempt to go to for example http://127.0.0.1:4040/ on any of my OSX browsers, it will eventually time out. The log file for this VM shows that it is correctly reading the settings and implying it's doing the right thing here: 00:00:08.286 NAT: set redirect TCP host port 4848 => guest port 4848 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 8084 => guest port 8084 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 4040 => guest port 4040 @ 127.0.0.1 00:00:08.286 NAT: set redirect TCP host port 7084 => guest port 7084 @ 127.0.0.1 00:00:08.290 Changing the VM state from 'LOADING' to 'SUSPENDED'. 00:00:08.290 Changing the VM state from 'SUSPENDED' to 'RESUMING'. 00:00:08.290 Changing the VM state from 'RESUMING' to 'RUNNING'. 00:00:08.337 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=000000012017d000 w=1834 h=929 bpp=32 cbLine=0x1CA8, flags=0x1 00:00:09.139 AIOMgr: Host limits number of active IO requests to 16. Expect a performance impact. 00:00:13.454 NAT: DHCP offered IP address 10.0.2.15 I've tried setting the Host IP to 127.0.0.1, and I've tried setting Guest IP blank and also 10.0.2.15. None of these seem to help. What else can I look at to troubleshoot this issue? Details of setup: OSX 10.6.8 Windows 7 Professional 64bit VirtualBox 4.1.2

  • Apache won't serve images larger than ~2K

    - by dtbaker
    Hello, Just upgraded an old box to Ubuntu to 10.04.2 LTS. Apache will not display images to a browser that are over about 2K. Small images seem to display fine. Static HTML and PHP continues to works fine as well. Installed: apache2 2.2.14-5ubuntu8.4 apache2-mpm-prefork 2.2.14-5ubuntu8.4 apache2-utils 2.2.14-5ubuntu8.4 apache2.2-bin 2.2.14-5ubuntu8.4 apache2.2-common 2.2.14-5ubuntu8.4 here is an ngrep of an image that doesn't display fine in the browser: T 192.168.0.4:32907 - 192.168.0.54:80 [AP] GET /path/path/logo.png HTTP/1.1..Host: 192.1 68.0.54..Connection: keep-alive..Accept: application/xml,application/xhtml+ xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5..User-Ag ent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.98 Safari/534.13..Accept-Enco ding: gzip,deflate,sdch..Accept-Language: en-US,en;q=0.8..Accept- Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3....

This looks ok to me! I have tried firefox and chrome, both display small images fine but when a large image is requested the browser prompts to download the file. When the image file is saved to the local computer it is corrupt, it also takes a long time to save which makes me think the browser cannot see the content-length header sent from apache. Also when I look at the saved image file it includes the headers from apache, along with a bit of garbage at the top, like so: vi logo.png: ^@^UÅd^@$^]V^S^H^@E^@^Q,n!@^@@^F^@^@À¨^@6À¨^@^D^@P^Y¬rÇŹéw^P^@Ú^@^@^A^A^H ^@^GÝ^]^@pbSHTTP/1.1 200 OK^M Date: Wed, 09 Mar 2011 04:47:04 GMT^M Server: Apache/2.2.14 (Ubuntu)^M Last-Modified: Tue, 05 Oct 2010 11:59:17 GMT^M ETag: "17b6ff-157c-491dd63eb2f40"^M Accept-Ranges: bytes^M Content-Length: 5500^M Keep-Alive: timeout=15, max=94^M Connection: Keep-Alive^M Content-Type: image/png^M ^M PNG^M etc... Any ideas? It's driving me nuts. There is nothing in apache error logs, and permissions are fine (because the image data is there, it's just somewhat corrupt). There's no proxy or iptables on this ubuntu box either. Thanks heaps!! Dave ps: just tried on IE from a different computer, same problem :( pps: rebooted server, no help.

  • How to get rid of Gmail's on "behalf of" using postfix

    - by user2815
    I'm using the default configuration of postfix on Ubuntu 9.04, and I've been trying to configure Gmail to send email through my server. I'm looking for a simple configuration for 10-15 users (like using a password file), but all the tutorials I have found have been too extensive and seem very enterprise-oriented. I just need to configure postfix with AUTH/TLS that is compatible with gmail.

  • lacp, cicso 3550, 3560, help with configuration

    - by Flamewires
    Hey all this is a repost from a question I asked on the cisco forums but never got a useful reply. Hey I'm trying to convert the FreeBSD servers at work to dual-gig lagg links from regular gigabit links. Our production servers are on a 3560. I have a small test environment on a 3550. I have achieved fail-over, but am having troubles achieving the speed increase. All servers are running gig intel (em) cards. The configs for the servers are: BSDServer: #!/bin/sh #bring up both interfaces ifconfig em0 up media 1000baseTX mediaopt full-duplex ifconfig em1 up media 1000baseTX mediaopt full-duplex #create the lagg interface ifconfig lagg0 create #set lagg0's protocol to lacp, add both cards to the interface, #and assign it em1's ip/netmask ifconfig lagg0 laggproto lacp laggport em0 laggport em1 ***.***.***.*** netmask 255.255.255.0 The switches are configured as follows: #clear out old junk no int Po1 default int range GigabitEthernet 0/15 - 16 # config ports interface range GigabitEthernet 0/15 - 16 description lagg-test switchport duplex full speed 1000 switchport access vlan 192 spanning-tree portfast channel-group 1 mode active channel-protocol lacp **** switchport trunk encapsulation dot1q **** no shutdown exit interface Port-channel 1 description lagginterface switchport access vlan 192 exit port-channel load-balance src-mac end obviously change 1000's to 100's and GigabitEthernet to FastEthernet for the 3550's config, as that switch has 100Mbit speed ports. With this config on the 3550, I get failover and 92Mbits/sec speed on both links, simultaneously, connecting to 2 hosts.(tested with iperf) Success. However this is only with the "switchport trunk encapsulation dot1q" line. First, I do not understand why I need this, I thought it was only for connecting switches. Is there some other setting which this turns on that is actually responsible for the speed increase? Second, This config does not work on the 3560. I get failover, but not the speed increase. Speeds drop from gig/sec to 500Mbit/sec when I make 2 simultaneous connections to the server with or without the encapsulation line. I should mention that both switches are using source-mac load balancing. In my test I am using Iperf. I have the server(lagg box) setup as the server(iperf -s), and the client computers are client(iperf -c server-ip-address), so the source mac(and IP) are different for both connections. Any ideas/corrections/questions would be helpful, as the gig switches are what I actually need the lagg links on. Ask if you need more information.

  • TTL for PTR records on Windows 2003 Server DNS

    - by Kyle Brandt
    When I look at the TTL (Time to Live) for PTR records (Reverse Lookup Zone) on one of our Windows 2003 DNS servers I see some are at 15 minutes, others are at 20. They have "Delete this record when it becomes stale" checked. These PTR records are for workstations that get IPs from Windows DHCP, so I think that creates the PTR records dynamically? How is TTL for these records set?
