  • Which CPU for XEN - LAMP testbed - Budget

    - by deploymonkey
    Dear serverfault knowledgeables, im in a decision dilemma right now, which I can't resolve due to lack of hands on experience. I need to build a testbed for basically virtualizing a LAMP application (os'ses not yet decided) including server side calculations. I'll opt for XEN since it seems better supported by cloud hosters at the moment. The hardware is for a proof of concept for a startup doing saas and might be used for closed live alpha/beta later on. After testing, the testbed might be a) deployed as a colocated white box server b) used as workstation Single socket is enough. We want to have ECC memory for reliability, this excludes most of the consumer line at intel. If intel CPU, then threaded cpu (HT) is preferred have at least 16 gig ram If justified by price and reliability is not too bad, a high quality desktop MB instead of a server MB would be worth a try It came down to the opteron 6128 vs. the xeon 5620 for me after a lot of research, but I don't necessarily have to be right. Which CPU is preferrable, concerning TCO (MB price, power requirements 24/7...) , Opteron 6128 or Xeon 5620? Which one offers better performance in real world applications? (Do You have any other suggestions I probably overlooked?) Thank You for Your consideration

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

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

  • Certificates required for WHQL-certified drivers

    - by Kasius
    The 64-bit Windows 7 image that we deploy to machines at our site does not contain all of the certificates included on a default Windows image. Automatic root certificate installation is also disabled per policy from higher in the organization. We have had a lot of trouble installing many WHQL-certified drivers from reputable companies (ex. HP, Lexmark, Dell, etc.), and I hypothesize that a required certificate is missing from one of the certificate stores on the machine. The error we typically get is: The driver cannot be installed because it is either not digitally signed or not signed in the appropriate manner. I know that it is signed. A .CAT file is included, and it has the following tree from top to bottom: Microsoft Root Authority (thumbprint a4 34 89 15 9a 52 0f 0d 93 d0 32 cc af 37 e7 fe 20 a8 b4 19) Microsoft Windows Hardware Compatibility PCA (thumbprint 93 b8 d8 82 0a 32 db 20 a5 ea b6 8d 86 ad 67 8e fa 14 ea 41) Microsoft Windows Hardware Compatibility Publisher (thumprint b0 50 45 45 42 4e be 2c 16 2f 62 5b bf 5a e6 9b 96 bf 0b 0b) What certificates are required to install WHQL-certified drivers? Is it possibly something other than certificates? Thanks! NOTE: I have posted this question on Technet as well, but honestly, I've never had a lot of luck posting questions on the Technet forums.

  • Keyboard doesn't function after Fedora 17 update

    - by mickburkejnr
    I updated my Fedora 16 installation to Fedora 17 on Saturday, and the update worked without reporting any errors. I carried on working on the machine in question and then switched the computer off. Last night I went back on the computer, I switched it on and got to the log in screen. At this point I tried to type in my password but the keyboard wouldn't work. I unplugged it (it's a PS/2 keyboard) and plugged it back in. The lights flashed for a split second but the keyboard still wouldn't work. I then plugged the keybaord in to a USB to PS/2 adapter, and the keyboard still wouldn't work. I restarted the computer and tried to access the BIOS and I was able to do so. So the keyboard doesn't seem to be faulty, it just doesn't work when Fedora boots in to the GUI interface. I did try to boot in to the "recovery mode" of Fedora, and the keyboard works here with no problem. As I still have access to Fedora via a terminal interface, is there anything I can do to fix the keyboard problem via the terminal without having to reinstall Fedora?

  • Delayed internet access

    - by Joel Coel
    When I (and presumably my users) first start up or log in to my computer I can't get internet access until several minutes after logging in. Internet pages like serverfault.com will time out. During this time I can access internal web servers. Sometimes pinging the gateway seems to fix the problem. I'm using Windows 7 on this machine with wifi, and the problem seems limited to the wifi network, which is on a separate vlan. The wired network does not share the problem, but I know it's not the wifi connection itself because the internal sites work. The wifi access point is attached to a 3Com 4200 switch, with the port set for vlan 2 untagged, vlan 1 tagged. The 4200 has a fiber connection to a 3Com 4900SX fiber switch that acts almost as a router here. The fiber connection is vlan 1 untagged vlan 2 tagged at both ends. The gateway is then attached to a different 4200 (vlan 1 untagged, vlan 2 tagged) that has a similar fiber connection to the 4900SX. vlan 2 has 192.168.8.0/22 IPs, vlan 1 has 10.1.0.0/16 IPs. The 4900SX has an interface for both vlans (10.1.1.1/192.168.8.1), as does the gateway (10.1.1.5/192.168.8.5). There is one dchp server for both vlans on the same switch as the gateway. It chooses a dhcp scope based on the interface used by the 4900sx to forward the dhcp request. There is also a network access list on the 4900sx set to deny all vlan2 traffic to any 10.1.x.x host, with exceptions made for a few servers, including dhcp, 4900sx, and the gateway. I think that about covers it. Any ideas on why internet access would be delayed like this?

  • Slowdown upon router/modem setup change

    - by Ollie Saunders
    I’ve been using a Belkin FSD7632-4 modem router to connect to my TalkTalk provided ADSL internet connection for some time and been pretty happy with it. Recently, however, the connection has been failing and I decided to get a ASUS RT-N16 instead, which is also a much more capable router generally. The ASUS RT-N16 doesn’t come with a modem built-in so I purchased as Zoom modem as well. I’ve set them both up and am using them to post this message. But I’m a bit miffed to find that I get a significantly and consistently slower downstream rate from the new configuration than with the old Belkin. Belkin modem router: downstream: 3.45 mbps upstream: 0.73 mbps ASUS router + Zoom modem: downstream: 2.71 mbps upstream: 0.66 mbps Any ideas why this is? The really weird thing about this is that the Zoom supports ADSL2 and ADSL2+ but I don’t think the old Belkin does. At first I thought it might be due to the Zoom modem being limited to PPPoE instead of PPPoA, which my ISP supports, but then I tried using PPPoE with the Belkin and that still gave a high speed. I’m using VC-Mux encapsulation with both. VPI of 0 and VCI of 38. I pulled this data off the Zoom: Mode: ADSL2 Line Coding: Trellis On Status: No Defect Link Power State: L0 Downstream Upstream SNR Margin (dB): 12.3 11.8 Attenuation (dB): 43.0 24.9 Output Power (dBm): 12.9 0.0 Attainable Rate (Kbps): 3936 844 Rate (Kbps): 3194 840 MSGc (number of bytes in overhead channel message): 59 10 B (number of bytes in Mux Data Frame): 99 14 M (number of Mux Data Frames in FEC Data Frame): 2 16 T (Mux Data Frames over sync bytes): 1 8 R (number of check bytes in FEC Data Frame): 8 8 S (ratio of FEC over PMD Data Frame length): 1.9833 9.0594 L (number of bits in PMD Data Frame): 839 219 D (interleaver depth): 32 2 Delay (msec): 15 4 Super Frames: 15808 14078 Super Frame Errors: 0 4294967232 RS Words: 513778 111753 RS Correctable Errors: 126 4294967238 RS Uncorrectable Errors: 0 N/A HEC Errors: 0 4294967279 OCD Errors: 0 0 LCD Errors: 0 0 Total Cells: 1920175 237597 Data Cells: 205993 392 Bit Errors: 0 0 Total ES: 0 0 Total SES: 0 0 Total UAS: 34 0

  • How to log kernel panics without KVM

    - by Spacedust
    My server is crashing and I can't find an answer why. It all started after my datacenter upgrade RAM from 16 GB to 32 GB. I also found such logs in dmesg - they've started to show itself just before the first kernel panic: EXT4-fs error (device md2): ext4_ext_find_extent: bad header/extent in inode #97911179: invalid magic - magic 5f69, entries 28769, max 26988(0), depth 24939(0) EXT4-fs error (device md2): ext4_ext_remove_space: bad header/extent in inode #97911179: invalid magic - magic 5f69, entries 28769, max 26988(0), depth 24939(0) EXT4-fs error (device md2): ext4_mb_generate_buddy: EXT4-fs: group 20974: 8589 blocks in bitmap, 54896 in gd JBD: Spotted dirty metadata buffer (dev = md2, blocknr = 0).

  • VT-x not enabled on 2010 Mac Pro

    - by BlindingDawn
    To start I had a Hackintosh as per the instructions from Lifehacker.com before and moved everything to a new 2010 8 Core Mac Pro. I opted for a restore from the time machine backup rather than using the migration assistance. I believe this may have caused more problems but one in particular is the lack of VT-x support. When I checked Parallels Desktop under "Host Hardware" information, I get the following that shows that VT-x isn't enabled. <Cpu dyn_lists=""> <Number>16</Number> <Model>Intel(R) Xeon(R) CPU E5620 @ 2.40GHz</Model> <Mode>1</Mode> <Speed>2400</Speed> <VtxEnabled>0</VtxEnabled> <VtxMode>1</VtxMode> 1) Does Parallels Desktop support using VT-x? 2) Does this setting show that my VT-x isn't enabled? 3) Is there a way of fixing it so that it is enabled? 4) Is there a way of using my Time Machine backup as if I'm doing a restore using migration assistance and just restore the files and settings?

  • Apache Mod SVN Access Forbidden

    - by Cerin
    How do you resolve the error svn: access to '/repos/!svn/vcc/default' forbidden? I recently upgraded a Fedora 13 server to 16, and now I'm trying to debug an access error with a Subversion server running on using Apache with mod_dav_svn. Running: svn ls http://myserver/repos/myproject/trunk Lists the correct files. But when I go to commit, I get the error: svn: access to '/repos/!svn/vcc/default' forbidden My Apache virtualhost for svn is: <VirtualHost *:80> ServerName svn.mydomain.com ServerAlias svn DocumentRoot "/var/www/html" <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory "/var/www/html"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> <Location /repos> Order allow,deny Allow from all DAV svn SVNPath /var/svn/repos SVNAutoversioning On # Authenticate with Kerberos AuthType Kerberos AuthName "Subversion Repository" KrbAuthRealms mydomain.com Krb5KeyTab /etc/httpd/conf/krb5.HTTP.keytab # Get people from LDAP AuthLDAPUrl ldap://ldap.mydomain.com/ou=people,dc=mydomain,dc=corp?uid # For any operations other than these, require an authenticated user. <LimitExcept GET PROPFIND OPTIONS REPORT> Require valid-user </LimitExcept> </Location> </VirtualHost> What's causing this error? EDIT: In my /var/log/httpd/error_log I'm seeing a lot of these: [Fri Jun 22 13:22:51 2012] [error] [client 10.157.10.144] ModSecurity: Warning. Operator LT matched 20 at TX:inbound_anomaly_score.

How do I change this?

  • Unable to connect to Windows VPN from iPad

    - by Justin
    I have a 16 GB iPad wifi I can't get to connect to VPN. The error I get is: "A connection could not be established to the PP server. Try reconnecting. If the problem continues, verify your settings and contact your Administrator." I have tried a variety of tasks to troubleshoot the issue: I have verified that another iPad on another network can connect to the VPN I am trying to connect to I can connect to this VPN from the same network the iPad uses on a Windows machine I have verified an iPhone user can connect to this VPN from a different network I have reset the iPad's network settings I have reset the entire iPad and restored settings I have compared my settings w/ a screenshot from the iPad that works and confirmed everything is correct I have used the IP address and domain name of our VPN server in the settings I have tried deleting the VPN settings in the iPad and recreating them I have verified in the logs of VPN server that I'm not even getting to the VPN server (no log entry) I have verified that I cannot VPN from the iPad on separate network (different ISP and router) Are there any other ways to troubleshoot VPN on an iPad?

  • Rate limiting bandwidth per IP

    - by Yohan
    First, I am not that good with computer. I even had problem with Windows PC. Right now I own a restaurant which happened to offer free internet. My ISP has my connection setup using a Ubuntu 11.1 box. IP Address is 192.168.1.16 with netmask 255.255.0.0, dns is 192.168.1.1 and gateway is 192.168.1.1. My problem is that my customers complains all day about slow network. When I received that kind of complain, the first thing came to my mind is to scout my area and find out who is the culprit, and ask him not to waste our bandwidth. Now, it is getting bored scouting people around, and I need to implement to my Linux box to limit bandwidth. I don't care if their provider can't be faster, but I want to limit 70kbit for each person. More annoying are people who use flashget and torrents. Usually they consume the biggest bandwidth. My question, how can I limit that? Please guide me in easy way. I've spent few days reading tc documents but doesn't understand a thing. I am using Ubuntu 11.10 Basically, I want all my customer get 70kbps each, no matter what.

  • using gmail as email relay for sendmail

    - by Nikita
    I used to be able to send emails using a gmail account & sendmail configured using one of the guides on the Internet, for example: http://appgirl.net/blog/configuring-sendmail-to-relay-through-gmail-smtp/ This is a small server and I've recently moved it to a different house. And sendmail has stop working. The only thing different in the network setup is a new router. What is happening: In the log files, I see the following error: ...stat=Deferred: smtp.gmail.com: No route to host When I run from the command line: strace sendmail -f A -t B -u "Subject" -m "Message" -tls=yes ssl=yes -s smtp.gmail.com:587 -xu A -xp XYZ It hangs on this call: recvfrom(3, "m0\201\203\0\1\0\0\0\0\0\0\4ares\3lan\0\0\34\0\1", 8192, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.254")}, [16]) = 26 close(3) = 0 time(NULL) = 1339997943 open("/etc/localtime", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb76ff000 read(3, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0\0\0\4\0\0\0\0"..., 4096) = 3477 _llseek(3, -24, [3453], SEEK_CUR) = 0 read(3, "\nEST5EDT,M3.2.0,M11.1.0\n", 4096) = 24 close(3) = 0 munmap(0xb76ff000, 4096) = 0 socket(PF_FILE, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 3 connect(3, {sa_family=AF_FILE, path="/dev/log"}, 110) = 0 send(3, "<18>Jun 18 01:39:03 sendmail[268"..., 96, MSG_NOSIGNAL) = 96 nanosleep({60, 0}, So it looks like at some point it tries to resolve the DNS name, but I don't have anything running on 53, so it dies out and then just hangs. The other interesting thing is that msmtp works just fine on the same server. Update: ares in strace output is actually the name of my server, but .254 IP address is the address of the router. Could anyone tell me why this is happening or what further steps can I take to investigate the issue? Thanks!

  • Varnish does not start properly (crashes after startup) with no error messages

    - by Matthew Savage
    I am running Varnish (2.0.4 from the Ubuntu unstable apt repository, though I have also used the standard repository) in a test environment (Virtual Machines) on Ubuntu 9.10, soon to be 10.04. When I have a working configuration and the server starts successfully it seems like everything is fine, however if, for whatever reason, I stop and then restart the varnish daemon it doesn't always startup properly, and there are no errors going into syslog or messages to indicate what might be wrong. If I run varnish in debug mode (-d) and issue start when prompted then 7 times out of time it will run, but occasionally it will just shut down 'silently'. My startup command is (the $1 allows for me to pass -d to the script this lives in): varnishd -a :80 $1 \ -T 127.0.0.1:6082 \ -s malloc,1GB \ -f /home/deploy/mysite.vcl \ -u deploy \ -g deploy \ -p obj_workspace=4096 \ -p sess_workspace=262144 \ -p listen_depth=2048 \ -p overflow_max=2000 \ -p ping_interval=2 \ -p log_hashstring=off \ -h classic,5000009 \ -p thread_pool_max=1000 \ -p lru_interval=60 \ -p esi_syntax=0x00000003 \ -p sess_timeout=10 \ -p thread_pools=1 \ -p thread_pool_min=100 \ -p shm_workspace=32768 \ -p thread_pool_add_delay=1 and the VCL looks like this: # nginx/passenger server, HTTP:81 backend default { .host = "127.0.0.1"; .port = "81"; } sub vcl_recv { # Don't cache the /useradmin or /admin path if (req.url ~ "^/(useradmin|admin|session|sessions|login|members|logout|forgot_password)") { pipe; } # If cache is 'regenerating' then allow for old cache to be served set req.grace = 2m; # Forward to cache lookup lookup; } # This should be obvious sub vcl_hit { deliver; } sub vcl_fetch { # See link #16, allow for old cache serving set obj.grace = 2m; if (req.url ~ "\.(png|gif|jpg|swf|css|js)$") { deliver; } remove obj.http.Set-Cookie; remove obj.http.Etag; set obj.http.Cache-Control = "no-cache"; set obj.ttl = 7d; deliver; } Any suggestions would be greatly appreciated, this is driving me absolutely crazy, especially because its such an inconsistent behaviour.

    I have 2 days since I am trying to fix this issue, with no success. The server is a mysql database server. Hardware: DELL Poweredge 1950, 2x Intel Xeon Quad Core E5345 @ 2.33GHz, 16 Gb mem, 2x 146Gb SAS (software RAID1) Software: Ubuntu 10.04.3 LTS, MySQL 5.1.41 Issue: while mysql is not used and runs with no database, everything seems alright. As soon as I install a database, it has the reason to bring all 8 cores in 100% with low memory consumption. So, you can imagine the load average goes high (I saw 212 load average for the first time). The server doesn't become unresponsive, but you can see it's slow while browsing the project installed. Additional info: the database used is not more than 24MB and it was moved from a server with less resources and a lot more larger databases. So it's not the database/project. my.cnf is not a reason also, as I used both default one and the one I use on the same distribution on another server.What is interesting is that mysql doesn't close any process and runs to the limit of the max_connections. Logs are quiet. Nothing there. I switched to this Ubuntu version after I suspected some problems in the newly Ubuntu 11.10 server. This one worked alright for an hour after I made a kernel upgrade to 3.0.1 (it was using the memory also) I tested disk speed and seems alright. Some more output on the running server: dstat -cndymlp -N total -D total 3: htop command: Idea? Did anyone meet the same problem? Any fix you can think of?

  • 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",

  • Setup: Eclipse in Ubuntu with Apache2 and Subversion

    - by Ricalsin
    Trying to setup Eclispe. I am running ubuntu 10.10 (Maverick). Apache2.2.16 Subversion 1.6.12 The Eclipse help/about/installed software says: Eclipse Platform 3.5.2 Subclipse 1.0.0 Version Control with Subversion 1.1.1 The Subclips wiki I followed is here I have installed the libsvn-java app as discussed. I added the line "-Djava.library.path=/usr/lib/jni" to the eclipse.ini file I checked the Eclipse help/about/confirguration settings and both of these lines are listed: eclipse.vmargs=-Djava.library.path=/usr/lib/jni java.library.path=/usr/lib/jni I checked that those files are in those directories. Still, when I check the preferencesteamsvn an error dialog shows: Failed to load JavaHL Library. These are the errors that were encountered: no libsvnjavahl.1 in java.library.path Incompatible JavaHL library loaded 1.3.x or later required I followed the "Testing JavaHL libraries" troubleshooting section at the bottom of the wiki: I downloaded the tarbal and ran it in a folder on my desktop with no problems. Then, I followed the instructions and placed that file INSIDE the path (usr/lib/jni/testJavaHL) and ran it from there. There are 50 tests performed and each one of them came back with this same error (posting only one for brevity): 50) testCommitRevprops(org.tigris.subversion.javahl.BasicTests)java.io.FileNotFoundException: /usr/lib/jni/testJavaHL/local_tmp/greek_files/iota (No such file or directory) at java.io.FileOutputStream.open(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:209) at java.io.FileOutputStream.<init>(FileOutputStream.java:160) at org.tigris.subversion.javahl.WC.materialize(WC.java:70) at org.tigris.subversion.javahl.SVNTests.buildGreekFiles(SVNTests.java:303) at org.tigris.subversion.javahl.SVNTests.setUp(SVNTests.java:222) at org.tigris.subversion.javahl.RunTests.main(RunTests.java:111) FAILURES!!! Tests run: 50, Failures: 0, Errors: 50 Any ideas as to how/why the "local_tmp/greek_files/iota" is appended to the directory? I assume that's my problem.. I'm also having a problem with newrepository location = ...as the directory location of my svn repository is one level above the home directory - which is prepended to whatever I place in the dialog box - resulting in this error: svn: '/home/ricalsin/file:/home/svn' does not exist Thank you for any help.

  • Change Windows Authentication user for Sql Server Management Studio

    - by Asmor
    We're using Sql Server 2005 with Windows Authentication setup. So normally, when you log in using e.g. Sql Server Management Studio, it forces you to log in at MACHINE_NAME\Username. Anyways, on this one particular computer, the person said they had to make a new account called User01 to do something and showed me where she'd created it under security in the "master" system database. And so now when she logs in, it's listed as MACHINE_NAME\User01 (not the actual Windows user name). It's still set to Windows Authentication, though, and I'm unable to change the login name. Now here's where the real problem comes in... I didn't realize that she was being logged in under this user name at the time, and I disabled it to see what would happen. Now I can't log into the server under her account. I created a new account in Windows called test, and as expected SSMS had the username as MACHINE_NAME\test, and I was able to log in fine. However, the area where the User01 account was listed is not visible to me as far as I can tell and so I can't reenable it. I also tried running the following query: alter login User01 ENABLE And got this error: Msg 15151, Level 16, State 1, Line 1 Cannot alter the login 'User01', because it does not exist or you do not have permission. So in a nutshell, ideally I'd like to reenable User01 somehow, just to get things back to where they used to be. Failing that, how can I force SSMS to log in using the Windows account name as it should be, rather than trying to use User01?

  • Best way to troubleshoot intermittent network outages?

    - by Ben Scheirman
    We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

  • Compressing and copying large files on Windows Server?

    - by Aaron
    I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

  • What's going on with traceroute?

    - by Kevin
    The following is what happens when I run traceroute from a certain location: # traceroute google.com traceroute to google.com (74.125.227.39), 30 hops max, 60 byte packets 1 gateway.local.enactpc.com (10.0.0.1) 0.138 ms 0.101 ms 0.084 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * 13 * * * 14 * * * 15 * * * 16 * * * 17 * * * 18 * * * 19 * * * 20 * * * 21 * * * 22 * * * 23 * * * 24 * * * 25 * * * 26 * * * 27 * * * 28 * * * 29 * * * 30 * * * Absolutely nothing of interest... Now, originally I thought this was just a fact of the location's network set up. (I assume they block pings or something...) However, watch what happens when I use nmap to run a traceroute... # nmap -sP --traceroute google.com Starting Nmap 5.21 ( http://nmap.org ) at 2012-09-25 22:18 CDT Nmap scan report for google.com (74.125.227.40) Host is up (0.034s latency). Hostname google.com resolves to 11 IPs.

Note, I checked, and the difference in target IP addresses is not related...

  • Hard Drive Compatibility with Motherboard

    - by Wesley
    Here are the current specs to put things in context: ECS P4VXASD2+ V5.0 Intel Pentium 4 Northwood 2.8 GHz 2x 512MB PC2100 DDR266 SDRAM Maxtor DiamondMax 10 250 GB PATA (IDE) HDD Gigabyte 52x CD-ROM NVIDIA TNT2 Pro 16 MB OKIA 300W ATX PSU USB bracket Modem PCI Before, I actually had a 300 GB hard drive installed. However, I read the FAQ for the motherboard and discovered that a maximum of 250 GB hard drive was supported. So I ended up finding the one listed above and put that in. However, upon booting up, I reset the BIOS to defaults and auto-detected all the drives installed. The 250 GB came up as something like 251.0 GB. I didn't think much about it until I tried to boot up a Windows XP installation disc. It booted up successfully and run for about a minute before the computer randomly rebooted. I've made sure that all the jumpers and settings are correct and everything has been installed correctly. I've tried running it without the addons and one stick of RAM but still the same thing. What else could be causing this problem?
