  • Why is my cron daemon is being killed every few minutes? OpenVZ?

    - by user113215
    As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap). With cron running, free -m reports: total used free shared buffers cached Mem: 1024 465 558 0 0 0 -/+ buffers/cache: 465 558 Swap: 0 0 0 My OpenVZ User Beancounters via cat /proc/user_beancounters: Version: 2.5 uid resource held maxheld barrier limit failcnt 172087: kmemsize 8275718 25561636 51200000 51200000 0 lockedpages 0 968 2048 2048 0 privvmpages 113442 266465 262200 262200 3740757 shmpages 788 4004 128000 128000 0 dummy 0 0 0 0 0 numproc 39 98 600 600 0 physpages 50521 208434 0 9223372036854775807 0 vmguarpages 0 0 512000 512000 0 oomguarpages 50521 208447 512000 512000 0 numtcpsock 7 323 4096 4096 0 numflock 7 64 2048 2048 0 numpty 1 4 32 32 0 numsiginfo 0 23 1024 1024 0 tcpsndbuf 137984 17878480 20480000 20480000 0 tcprcvbuf 114688 6983504 20480000 20480000 0 othersockbuf 162960 1074440 20480000 20480000 0 dgramrcvbuf 0 24208 10240000 10240000 0 numothersock 101 353 2048 2048 0 dcachesize 459171 747444 10240000 10240000 0 numfile 1010 4221 50000 50000 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 39 424 2048 2048 0

  • KeePass justification

    - by Jeff Walker
    I work at a place that tries to take security seriously, but sadly, they often fail. Currently, one of the major ways they fail is password management. I personally have about 20 accounts (my personal user id on lots of machines). For shared "system" accounts, there are about 45 per environment; development, test, and production. I have access to 2 of those, so my personal total is somewhere around 115 accounts. Passwords have to be at least 15 characters with some extensive but standard complexity constraints, and have to be changed every 60 days or so (system accounts every year). They also should not be the same for different accounts, but that isn't enforced. Think DoD-type standards. There is no way to remember and keep up with this. It just isn't humanly possible, as far as I'm concerned. This might be a good justification of a centralized account management system, a la LDAP or ActiveDirectory, but that is a totally different battle. Currently the solution is an Excel spreadsheet. They use Excel to put a password on it, and then most people make a copy and remove the password. This makes my stomach turn. I use KeePass for this problem and it manages all of my account very well. I like the features like auto-typing, grouping, plugins, password generation, etc. It uses AES-256 encryption via the .Net framework, and while not FIPS compliant, it has a very good reputation. The only problem is that they are also very careful about using randomly downloaded software. So we have to justify every piece of software on our workstations. I have been told that they really don't want me to use this, be cause of the "sensitive nature" of storing passwords. sigh My justification has to be "VERY VERY strong". I have been tasked with writing a justification for KeePass, but as I am lazy, I would like any input that I can get from the community. What do you recommend? Is there something out there that is better or more respected than KeePass? Is there any security experts saying interesting things on this topic? Anything will help at this point. Thanks.

  • IKE Phase 1 Aggressive Mode exchange does not complete

    - by Isaac Sutherland
    I've configured a 3G IP Gateway of mine to connect using IKE Phase 1 Aggressive Mode with PSK to my openswan installation running on Ubuntu server 12.04. I've configured openswan as follows: /etc/ipsec.conf: version 2.0 config setup nat_traversal=yes virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16,%v4:172.16.0.0/12 oe=off protostack=netkey conn net-to-net authby=secret left=192.168.0.11 [email protected] leftsubnet=10.1.0.0/16 leftsourceip=10.1.0.1 right=%any [email protected] rightsubnet=192.168.127.0/24 rightsourceip=192.168.127.254 aggrmode=yes ike=aes128-md5;modp1536 auto=add /etc/ipsec.secrets: @left.paxcoda.com @right.paxcoda.com: PSK "testpassword" Note that both left and right are NAT'd, with dynamic public IP's. My left ISP gives my router a public IP, but my right ISP gives me a shared dynamic public IP and dynamic private IP. I have dynamic dns for the public ip on the left side. Here is what I see when I sniff the ISAKMP protocol: 21:17:31.228715 IP (tos 0x0, ttl 235, id 43639, offset 0, flags [none], proto UDP (17), length 437) 74.198.87.93.49604 > 192.168.0.11.isakmp: [udp sum ok] isakmp 1.0 msgid 00000000 cookie da31a7896e2a1958->0000000000000000: phase 1 I agg: (sa: doi=ipsec situation=identity (p: #1 protoid=isakmp transform=1 (t: #1 id=ike (type=enc value=aes)(type=keylen value=0080)(type=hash value=md5)(type=auth value=preshared)(type=group desc value=modp1536)(type=lifetype value=sec)(type=lifeduration len=4 value=00015180)))) (ke: key len=192) (nonce: n len=16 data=(da31a7896e2a19582b33...0000001462b01880674b3739630ca7558cec8a89)) (id: idtype=FQDN protoid=0 port=0 len=17 right.paxcoda.com) (vid: len=16) (vid: len=16) (vid: len=16) (vid: len=16) 21:17:31.236720 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 456) 192.168.0.11.isakmp > 74.198.87.93.49604: [bad udp cksum 0x649c -> 0xcd2f!] isakmp 1.0 msgid 00000000 cookie da31a7896e2a1958->5b9776d4ea8b61b7: phase 1 R agg: (sa: doi=ipsec situation=identity (p: #1 protoid=isakmp transform=1 (t: #1 id=ike (type=enc value=aes)(type=keylen value=0080)(type=hash value=md5)(type=auth value=preshared)(type=group desc value=modp1536)(type=lifetype value=sec)(type=lifeduration len=4 value=00015180)))) (ke: key len=192) (nonce: n len=16 data=(32ccefcb793afb368975...000000144a131c81070358455c5728f20e95452f)) (id: idtype=FQDN protoid=0 port=0 len=16 left.paxcoda.com) (hash: len=16) (vid: len=16) (pay20) (pay20) (vid: len=16) However, my 3G Gateway (on the right) doesn't respond, and I don't know why. I think left's response is indeed getting through to my gateway, because in another question, I was trying to set up a similar scenario with Main Mode IKE, and in that case it looks as though at least one of the three 2-way main mode exchanges succeeded. What other explanation for the failure is there? (The 3G Gateway I'm using on the right is a Moxa G3150, by the way.)

  • MySQL Execution Time Spikes

    - by Brett
    I am having issues with MySQL all of the sudden today. Details: OS: CentOS release 5.7 Server type: Parallels virtuozzo container running on mediatemple DV 4.0 package Average total memory usage: <500mb Total memory usage allowed: 1gb (part of shared pool for emergency only, users are only guaranteed 500mb) Processor: 1ghz Main database sizes with most usage: 275mb & 107mb server stack: nginx 1.0.10, mysql 5.1.54, php 5.3.8 with php-fpm innodb_buffer_pool_size=100M php-fpm max children: 5 Webapps: custom php-based sites, magento & drupal slow query timeout is set to 1 second Steps I completed towards diagnosis: Cannot restart container yet - I will try later tonight when our domestic traffic has dropped Enabled mysql and php-fpm slowlog. Found functions that did DB queries in php-fpm slowlog were taking over 1s to complete at times Found some simple queries in mysql slowlog taking well over 1s to complete that should take less than 1s. Most interesting - execution time seems to spike at times. A query will take .2s a couple times, then one time it will take 8s to run the same query. These results were verified by running raw SQL queries through mysql command line. Top does not reveal anything too interesting Only resource related thing i can see is load averages much higher than normal Up until today, mysql has been fine, there have been no major changes to the db since yesterday. Sometimes things are so bad, I am seeing bad gateway errors after 60s of execution time. Innodb is doing on average 300-1400 reads/sec. Mysql is doing 3-10 queries/sec slow query count in 2 hours uptime is 171 (with slow timeout at 1 second) Tried restarting mysql, nginx, php-fpm multiple times For example: UPDATE `catalogsearch_query` SET `query_text` = 'EW 90', `num_results` = '7532', `popularity` = '99180', `redirect` = NULL, `synonym_for` = NULL, `store_id` = '1', `display_in_terms` = '1', `is_active` = '1', `is_processed` = '1', `updated_at` = '2012-05-08 21:38:31' WHERE (query_id='31'); This query took 17sec to complete one time, rest of the time around .079 sec. But varies, sometimes 1sec, sometimes .004 sec. This is running the same query, over and over with a couple seconds time in between each. Most tables are innodb, and sometimes I noticed the lock time taking 90% of the query execution time, but most of the time lock time is insignificant. Any idea what's going on here?

  • Critique My Backup and Storage Plan

    - by MetaHyperBolic
    My current storage (RAID-1 off of a hardware RAID card) and backup (a spare drive) solutions for my home network are inadequate. I have too much data scattered on various one-off drives. It is time to evolve. Backups seem simple enough, at least: lots of big drives. However, I am bewildered by the number of choices for small home storage. The Drobo S looks appealing. So does the ReadyNAS. I am not looking for bunches of shiny features, I'm mostly interested in reliability. I am not interested in building Yet Another PC to create a file server or doing something in the cloud, or whatever. I'm stupid, so I am keeping it simple. Requirements for Main Volume: Starting working space roughly 2TB, with options for growth up to 5TB RAID or something RAID-like with at least one parity drive eSATA II for speed during backups Ability to shut down gracefully when alerted of low power by a UPS Optional but Desirable: Will take 2TB drives now with options for the larger 3TB drives coming in 2010-2011 Optional but Desirable: : RAID-6 or something similar, with two parity drives Optional but Desirable: : Hot spare Ethernet connection not required, as the volume will be shared via the same machines which runs my home print server Backups: Backup performed via ROBOCOPY in mirror mode to an external hard drive via a eSATA II connection. Start with rotating between two external 2TB hard drives, will go up to six external 2TB drives. Start with a weekly backup, move to a bi-weekly backup as more drives are added. Move to 3TB drives as the size of my main volume increases. Backup drives will be stored on an off-site location. Hard drives: I plan on buying all of the same model, but different batches from different vendors. I found a "burn-in" utility with which I can pound away on the drives for a couple of weeks before adding them to the backup pool or the main volume. I estimate that I am looking at roughly $1,500 to start, once I start throwing in two TB drives for backup and four for storage. So, are there any obvious flaws in my plan? What have I overlooked? Any suggestions for the storage device for my main volume that fits my requirements? Or do I just keep it simple, 2 drives in RAID-1, then perform due diligence with my backups, accepting that I will have to buy a whole new unit when my data grows past 2TB?

  • Suggestions for sharing and using data between Ubuntu and Windows 7 dual boot

    - by wizjany
    Note: TL;DR, scroll to bottom for summary. I recently set up my computer for a dual boot between Ubuntu 9.10 and Windows 7. My current drive setup is as follows. | A1 | A2 | | B1 | B2 | B3 | A1: 100 mb, windows 7 "System Reserved" boot partition A2: 230 gb, data section, this one needs to be shared between the operating systems B1: 125 gb, windows 7 OS B2: 123 gb, ubuntu OS B3: 2gb, linux swap space Pretty much i want to have my documents, music, pictures, videos, etc accessible from both operating systems. My first attempt involved making the data (a2) partition NTFS, and moving my home folder from ubuntu to the data partition. However, as I read NTFS does not work nice with permission, and it messed up my home folder. My next idea is one of the following: 1) format the data partition to ext2/3/4 and move my home folder from linux there, and get a driver to read ext partitions in windows 7. The problem with that is that most of the ext drivers/software are not compatible with windows 7 or do not integrate with windows explorer (I really don't want to open a separate software window just to access my data, plus it's probably not compatible with other software.) http://www.fs-driver.org/ looks promising, but I'm not sure how it works with ext4 and windows 7 (not officially supported, when trying in vista compatibility mode, it tells me I need to format the ext drive to use it). My next idea, 2) keep the home folder in ubuntu where it is, but create symlinks for the Documents, Music, etc folders to an NTFS formatted Data (A2) partition, and add those locations to the windows 7 libraries. I'm not totally sure how the permissions would work out, but it should be fine since it's only the documents, music, etc and not the important config files in the rest of /home/user/. Correct me if I'm wrong. Currently, symlinks is my best idea, although i'm not sure how it will work. Any suggestions, additions to my ideas, links, pointers, whatever would be greatly appreciated. Even if it means i should reformat both my drives and repartition (2 250gb drives if you want to suggest a setup for that), I won't be too opposed if that's the best suggestion (I've gone through the format/install/format/reinstall process 5 times over the past 3 days, once more won't hurt me). TL;DR, summary: I have two hard drives. One is partitioned for Ubuntu and Windows 7, the second one I want accessible to both operating systems to store documents, music, pictures, videos, etc. Suggestions on how to set up the data drive please =) P.S. bonus if I can get an apache server document root folder working between the two OS's as well (permissions could become very complicated, so don't worry too much about that) P.P.S. Related question, but data viewing is one way: http://superuser.com/questions/84586/partition-scheme-and-size-for-dual-boot-windows-7-and-ubuntu-9-10-with-separate-p

  • Intermittently, IIS7 requests get stuck in WindowsAuthenticationModule

    - by rbeier
    Hi, We're running an IIS7 server hosting several dozen websites. Several of these websites are all part of the same legacy app we've developed. These sites all run the same code and run in the same app pool. Roughly once a month over the past few months, we've found that all requests for this app pool start hanging indefinitely. When this happens, we receive an alert and we recycle the app pool. After that, the sites start working again. This only ever affects this one app pool - never any others on the same server. A couple times, before recycling the pool, I've looked at the currently-executing requests in the worker process. They all show up as executing inside the WindowsAuthenticationModule. Which is strange, because the vast majority of the application does not require authentication. There is a small admin section which uses Windows auth... but all the other requests should be anonymous. Does anyone have any idea as to what might be causing this? There are several unusual things about the way these sites are set up. As I mentioned, they all run the same code - multiple sites point at the same physical directory. The only difference is the host header bindings. I'm not sure why there isn't just one site with all the host headers, but that's how it works. In several of these sites, the same physical directory is mapped at two levels - as the root of the site and again as an application within the site. So if a user goes to http://oursite.com/index.aspx, that maps to c:\files\oursite\index.aspx. If a user goes to http://oursite.com/foo/index.aspx, that also maps to c:\files\oursite\index.aspx. I think there is code which looks at the request URL and handles the two requests differently. This is strange because the same web.config ends up being interpreted as a site config file, and also as an application config file within the site. I don't know if this might be related to the authentication problem. If we can't find the cause, we're thinking of a few workarounds we could try: Move the admin section into a separate site, and give the client a new admin URL. Run that separate site in its own app pool. Then in the web.config shared by all the other sites, remove the WindowsAuthenticationModule. That way there should be no possibility of a hang within the WindowsAuthenticationModule. Try running all these sites in the classic pipeline instead of the integrated pipeline. They were working fine on our old IIS6 server... (If we get desperate) Set up a watchdog script which monitors the sites and auto-recycles the app pool when it detects that requests are getting stuck. What do you think? Thanks for your help, Richard

  • How to configure DNS so that www.example.com goes to one server, *.example.com to another

    - by fishwebby
    I'm trying to set up my domain as follows, but I'm not actually sure if it's possible. I have a domain where I would like the base and www addresses to go to my static site, but others to go to my application server. For example: My domain is registered with Dreamhost, and my application is on a VPS at Webbynode. I've set up the domain in Dreamhost to use Webbynode's nameservers: ns1.dnswebby.com ns2.dnswebby.com ns3.dnswebby.com And in Webbynode I've set up a wildcard A record to point to the IP address of my VPS: * 1.2.3.4 A and this works nicely, if I go to app.example.com it resolves to my application server at Webbynode. However, what I'd like to do is have example.com and www.example.com go to my static site, hosted back at Dreamhost, whilst still having any other domain go to my app. What I've done to try and achieve this is set up these DNS "NS" entries at Webbynode, trying to get Dreamhost to resolve these domain names: (empty) ns1.dreamhost.com NS (empty) ns2.dreamhost.com NS (empty) ns3.dreamhost.com NS www ns1.dreamhost.com NS www ns2.dreamhost.com NS www ns3.dreamhost.com NS (I don't have a fixed IP address at Dreamhost so I can't just set up simple A records). However this doesn't work... does anyone have any idea if this is possible and if so how it could be done? Update: I've got this working now, as above for the domain (i.e. registered with Dreamhost, but using Webbynode's nameservers). To delegate the DNS for www.example.com to Dreamhost, I've got the following DNS entries set up: www.example.com. ns1.dreamhost.com. NS www.example.com. ns2.dreamhost.com. NS www.example.com. ns3.dreamhost.com. NS (note the full stops at the end) And to get example.com to resolve to my static site, I set up CNAME record: example.com. www.example.com. CNAME So now, example.com and www.example.com go to my static site on Dreamhost, and if they change the IP address of my shared hosting it won't affect me, and all other subdomains go to my application server. This seems to work nicely, but if anyone knows a better way to do it I'd be happy to hear it. Thanks to all who replied.

  • broken apache .htaccess (mod_rewrite)

    - by Tim
    Hey there, I'm running into an apache mod_rewrite configuration issue on one of our machines. Has anyone encountered / overcome anyone of these issues. URL1 ( http://www.uppereast.com ) is not being redirected to URL2 ( http://www.nyclocalliving.com ). This definitely worked in my test environment where a localhost address was rewritten to URL2 ( RewriteRule ^http://upe.localhost$ http://www.nyclocalliving.com ). I'm trying to get the all of the redirect rules working ( 2200 + ), but the 'http://www.nyclocalliving.com' site encounters a server error if I use more that 1000 or more rules. A) .htaccess file - I've tried the simplest approach which worked in a local environment 75 # Various rewrite rules. 76 <IfModule mod_rewrite.c> 77 RewriteEngine on 78 79 # BEGIN new URL Mapping rules 80 #RewriteRule ^http://www.uppereast.com/$ http://www.nyclocalliving.com ... 2307 #RewriteRule ^http://www.uppereast.com/zipcodechange.html$ http://www.nyclocalliving.com/zip-code-change fig. 1 B) /var/log/httpd/error_log file - there are these seg. fault errors when I enable the first rule ( line 80 ). no error logs otherwise. 1893 [Fri Sep 25 17:53:46 2009] [notice] Digest: generating secret for digest authentication ... 1894 [Fri Sep 25 17:53:46 2009] [notice] Digest: done 1895 [Fri Sep 25 17:53:46 2009] [notice] Apache/2.2.3 (CentOS) configured -- resuming normal operations 1896 [Fri Sep 25 17:53:47 2009] [notice] child pid 29774 exit signal Segmentation fault (11) 1897 [Fri Sep 25 17:53:47 2009] [notice] child pid 29775 exit signal Segmentation fault (11) 1898 [Fri Sep 25 17:53:47 2009] [notice] child pid 29776 exit signal Segmentation fault (11) 1899 [Fri Sep 25 17:53:47 2009] [notice] child pid 29777 exit signal Segmentation fault (11) 1900 [Fri Sep 25 17:53:47 2009] [notice] child pid 29778 exit signal Segmentation fault (11) 1901 [Fri Sep 25 17:53:47 2009] [notice] child pid 29779 exit signal Segmentation fault (11) fig. 2 C) Some more debug information from the shell; the mod_rewrite is turned on and this is the machine architecture 1 # apachectl -t -D DUMP_MODULES | more 2 Loaded Modules: 3 core_module (static) 4 ... 5 rewrite_module (shared) 1 # uname -a 2 Linux RegionalWeb 2.6.24-23-xen #1 SMP Mon Jan 26 03:09:12 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux fig. 3 I looked into some previous posts (http://serverfault.com/questions/18744/htaccess-not-working-modrewrite), but didn't find a solution for this. I'm sure there's a small switch somewhere that I'm missing. Thanks in advance Tim

  • Apache and MySQL taking all the memory? Maximum connections?

    - by lpfavreau
    I've a had one of our servers going down (network wise) but keeping its uptime (so looks the server is not losing its power) recently. I've asked my hosting company to investigate and I've been told, after investigation, that Apache and MySQL were at all time using 80% of the memory and peaking at 95% and that I might be needing to add some more RAM to the server. One of their justifications to adding more RAM was that I was using the default max connections setting (125 for MySQL and 150 for Apache) and that for handling those 150 simultaneous connections, I would need at least 3Gb of memory instead of the 1Gb I have at the moment. Now, I understand that tweaking the max connections might be better than me leaving the default setting although I didn't feel it was a concern at the moment, having had servers with the same configuration handle more traffic than the current 1 or 2 visitors before the lunch, telling myself I'd tweak it depending on the visits pattern later. I've also always known Apache was more memory hungry under default settings than its competitor such as nginx and lighttpd. Nonetheless, looking at the stats of my machine, I'm trying to see how my hosting company got those numbers. I'm getting: # free -m total used free shared buffers cached Mem: 1000 944 56 0 148 725 -/+ buffers/cache: 71 929 Swap: 1953 0 1953 Which I guess means that yes, the server is reserving around 95% of its memory at the moment but I also thought it meant that only 71 out of the 1000 total were really used by the applications at the moment looking a the buffers/cache row. Also I don't see any swapping: # vmstat 60 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 57612 151704 742596 0 0 1 1 3 11 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 1 1 24 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 2 1 18 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 0 1 13 0 0 100 0 And finally, while requesting a page: top - 08:33:19 up 3 days, 13:11, 2 users, load average: 0.06, 0.02, 0.00 Tasks: 81 total, 1 running, 80 sleeping, 0 stopped, 0 zombie Cpu(s): 1.3%us, 0.3%sy, 0.0%ni, 98.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1024616k total, 976744k used, 47872k free, 151716k buffers Swap: 2000052k total, 0k used, 2000052k free, 742596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24914 www-data 20 0 26296 8640 3724 S 2 0.8 0:00.06 apache2 23785 mysql 20 0 125m 18m 5268 S 1 1.9 0:04.54 mysqld 24491 www-data 20 0 25828 7488 3180 S 1 0.7 0:00.02 apache2 1 root 20 0 2844 1688 544 S 0 0.2 0:01.30 init ... So, I'd like to know, experts of serverfault: Do I really need more RAM at the moment? How do they calculate that for 150 simultaneous connections I'd need 3Gb? Thanks for your help!

  • Remote installing an msi on citrix servers using WMI

    - by capn
    OK, I'm a C# programmer that is trying to streamline the deployment of a custom windows form app I inherited and built an installer for with WiX (this app will need to be reinstalled regularly as I'm making changes to it). I'm not really used to admin type things (or vbs, or WMI, or terminal servers, or Citrix, and even WiX and MSI are not things I usually deal with) but so far I put together some vbs and have an end goal in mind. The msi does work, and I've installed it from the mapped O: drive on my dev machine and while RDP'd to a citrix machine. End Goal: Deploy code written on my dev machine and compiled into an MSI (that I can improve upon within the confines of WiX and whatever the Windows Installer Engine allows) to the cluster of Citrix machines my users have access to. What am I missing in my script to get the MSI to execute on the remote machines? Layout: Machine A is my dev machine, and has the vbs script and the msi file (XP SP3) Machines C1 - C6 are the Citrix Servers that need the application installed them via the msi (Server 2003 R2 SP2) There is also optionally a shared network resource that all the machines can access. Script: 'Set WMI Constants Const wbemImpersonationLevelImpersonate = 3 Const wbemAuthenticationLevelPktPrivacy = 6 'Set whether this is installing to the debug Citrix Servers Const isDebug = true 'Set MSI location 'Network location yields error 1619 (This installation package could not be opened.) msiLocation = "\\255.255.255.255\odrive\Citrix Deployment\Setup.msi" 'Directory on machine A yields error 3 (file not found) 'msiLocation = "C:\Temp\Deploy\Setup.msi" 'Mapped network drive (on both machines) yield error 3 (file not found) 'msiLocation = "O:\Citrix Deployment\Setup.msi" 'Set login information strDomain = "MyDomain" Wscript.StdOut.Write "user name:" strUser = Wscript.StdIn.ReadLine Set objPassword = CreateObject("ScriptPW.Password") Wscript.StdOut.Write "password:" strPassword = objPassword.GetPassword() 'Names of Citrix Servers Dim citrixServerArray If isDebug Then citrixServerArray = array("C4") Else 'citrixServerArray = array("C1","C2","C3","C5","C6") End If 'Loop through each Citrix Server For Each citrixServer in citrixServerArray 'Login to remote computer Set objLocator = CreateObject("WbemScripting.SWbemLocator") Set objWMIService = objLocator.ConnectServer(citrixServer, _ "root\cimv2", _ strUser, _ strPassword, _ "MS_409", _ "ntlmdomain:" + strDomain) 'Set Remote Impersonation level objWMIService.Security_.ImpersonationLevel = wbemImpersonationLevelImpersonate objWMIService.Security_.AuthenticationLevel = wbemAuthenticationLevelPktPrivacy 'Reference to a process on the machine Dim objProcess : Set objProcess = objWMIService.Get("Win32_Process") 'Change user to install for terminal services errReturn = objProcess.Create _ ("cmd.exe /c change user /install", Null, Null, intProcessID) WScript.Echo errReturn 'Install MSI here 'Reference to a product on the machine Set objSoftware = objWMIService.Get("Win32_Product") 'All users set in option parameter, I'm led to believe that the third parameter is actually ignored 'http://www.webmasterkb.com/Uwe/Forum.aspx/vbscript/2433/Installing-programs-with-VbScript errReturn = objSoftware.Install(msiLocation,"ALLUSERS=2 REBOOT=ReallySuppress",True) Wscript.Echo errReturn 'Change user back to execute errReturn = objProcess.Create _ ("cmd.exe /c change user /execute", Null, Null, intProcessID) WScript.Echo errReturn Next I also tried using this to install, it doesn't return an error code, but doesn't install the msi either, and it makes me wonder if the change user /install command is even really working. errReturn = objProcess.Create _ ("cmd.exe /c msiexec /i ""O:\Citrix Deployment\Setup.msi"" /quiet") Wscript.Echo errReturn

  • File/folder permissions and groups on Linux with Apache

    - by phobia
    I'm trying to learn about permissions on linux webserver with apache. Some clues to the system: The server I have to play around with is Fedora based. Apache runs as apache:apache. To allow for e.g. php to write to a file the file needs to be chmod 777. 755 is not sufficiant. What I'm wondering is basically how set up permissions like they should be on e.g. a "shared web host". My main problem is that if I set a permission so that one user cannot access anothers home folder, then apache can't read from the public_html folder either. To keep the users out I need to set chmod 700. But to let apache to read I need to have at least execute on world, so a 701 basically works, but won't let some users in. So I'm really stuck on what to do. Have been concidering adding the apache user to the frous grours below to avoid having to add the world execute flag, but is that a bad thing? Should it be the other way around, the users in the groups below should also be in the apache group? I was aiming at having 4 groups: 1. webapp same as dev_int, but is the only one that can go inside the webapp/live folder to e.g. do an update from the repo. 2. dev_int can read,write and execute everything in the "web root", including the two below, but nothing outside of the web root 3. dev_ext can read write and execute in all client folders, but cannot access anything outside of the webapp root 4. clientsBasic ftp accounts. Has a home folder with a public_html, but cannot access any other home folders An example of folder structure: webroot    no users in the aforementioned groups can go outside of here some_project    :dev_int only webapp live    :webapp only staging    :dev_int and :dev_ext clients    :dev_int and :dev_ext client_1    :dev_int, :dev_ext and client1:clients public_html dev developer_1    developer_1:dev_int OR :dev_ext public_html

  • Varnish, hide port number

    - by George Reith
    My set up is as follows: OS: CentOS 6.2 running on an OpenVZ virtual machine. Web server: Nginx listening on port 8080 Reverse proxy: Varnish listening on port 80 The problem is that Varnish redirects my requests to port 8080 and this appears in the address bar like so http://mysite.com:8080/directory/, causing relative links on the site to include the port number (8080) in the request and thus bypassing Varnish. The site is powered by WordPress. How do I allow Varnish to use Nginx as the backend on port 8080 without appending the port number to the address? Edit: Varnish is set up like so: I have told the Varnish daemon to listen to port 80 by default.

  • Adobe Reader not loading form content

    - by wullxz
    We have an FDL file which is used to offer an online application possibility. The FDL is filled out and sent to a mailbox. When I open the received file, Adobe Reader starts, loads the document in Internet Explorer (had to change my default browser because it doesn't work in chrome - the customer uses IE as default) and displays a warning that Adobe Reader has blocked the connection to the server where the initial document is saved: I can then click on "Trust this document once" (translated by me!) or "Add this host to trusted hosts" (also translated by me!). The second option doesn't work at all. The first option works but is a little bit annoying. I looked into Adobe Readers options (Edit - "Voreinstellungen" in german / the last option - Security (advanced)) and found the possibility to add hosts, files and directories or allow Adobe Reader to use the "Trusted Websites" list from Internetoptions. When I add the website either to Trusted Websites or the trusted list in Adobe Readers options, the warning doesn't pop up but the content in the prefilled (by the applicant) input boxes of the document doesn't show up on Windows 7 but it does show up on Windows XP. This Screenshot shows the settings window described in the last paragraph. The big input box at the bottom normally holds the trusted files/directories/hosts list. System Information: Windows 7 Enterprise x64 Adobe Reader X multiple IE versions (mine is latest but there's also IE 7 or 8) How do I get Adobe Reader to load the content of the form? This behaviour can be reproduced on a PC. When opening an fdf from a command line the form fields are blank even though there is data in the fdf and the pdf is located in a mnaully entered trsuted folder. Steps to reproduce: Clean install a Windows 7 PC (or use a virtual box) Map a network drive to a shared folder with a subfolder e.g. c:\test\docs becomes m:\docs Set security permissions to allow full control to everyone Add an fdf and a matching pdf file in the subfolder Manually add m:\docs to each of the trusted folders in the trust manager registry settings Ensure that Enhanced Security is on Run a command line to open the fdf file Expected result: pdf is opened in Adobe Reader with form fields filled out with data Actual results: pdf is opened with blank fields 'Yellow bar' appears asking to add document to trusted locations It appears that Adobe Reader XI is ignoring the privileged locations entries in the registry. Adding the document via the 'yellow bar' adds the individual document, with the same folder, to the privileged locations but means that the process has to be repeated for every document that needs to be opened from the folder.

  • Aliased network interfaces and isc dhcp server

    - by Jonatan
    I have been banging my head on this for a long time now. There are many discussions on the net about this and similar problems, but none of the solutions seems to work for me. I have a Debian server with two ethernet network interfaces. One of them is connected to internet, while the other is connected to my LAN. The LAN network is 10.11.100.0 (netmask 255.255.255.0). We have some custom hardware that use network 10.4.1.0 (netmask 255.255.255.0) and we can't change that. But we need all hosts on 10.11.100.0 to be able to connect to devices on 10.4.1.0. So I added an alias for the LAN network interface so that the Debian server acts as a gateway between 10.11.100.0 and 10.4.1.0. But then the dhcp server stopped working. The log says: No subnet declaration for eth1:0 (no IPv4 addresses). ** Ignoring requests on eth1:0. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** No subnet declaration for eth1:1 (no IPv4 addresses). ** Ignoring requests on eth1:1. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface eth1:1 is attached. ** I had another server before, also running Debian but with the older dhcp3 server, and it worked without any problems. I've tried everything I can think of in dhcpd.conf etc, and I've also compared with the working configuration in the old server. The dhcp server need only handle devices on 10.11.100.0. Any hints? Here's all relevant config files: /etc/default/isc-dhcp-server INTERFACES="eth1" /etc/network/interfaces (I've left out eth0, that connects to the Internet, since there is no problem with that.) auto eth1:0 iface eth1:0 inet static address 10.11.100.202 netmask 255.255.255.0 auto eth1:1 iface eth1:1 inet static address 10.4.1.248 netmask 255.255.255.0 /etc/dhcp/dhcpd.conf ddns-update-style none; option domain-name "???.com"; option domain-name-servers ?.?.?.?; default-lease-time 86400; max-lease-time 604800; authorative; subnet 10.11.100.0 netmask 255.255.255.0 { option subnet-mask 255.255.255.0; pool { range 10.11.100.50 10.11.100.99; } option routers 10.11.100.102; } I have tried to add shared-network etc, but didn't manage to get that to work. I get the same error message no matter what...

  • Snow Leopard can see Windows shares in Finder but can't connect

    - by Randy Miller
    I have an iMac with the latest version of Snow Leopard on it. I have a NAS drive and a Windows machine that both show up in the Finder's 'Shared' section. However, if I click on them, Finder says "Connection Failed". Clicking on 'Connect As...' gives an error dialog that says "The server 'blah' may not exist or it is unavailable at this time." Points of interest: All machines are receiving their IP/DNS info from the router using DHCP. I have a Mac Mini on the same network that connects to the NAS drive and windows machine perfectly with no config (i.e. worked out of the box). Both Macs are on the same version of Snow Leopard. There is no password required to access the NAS share. I've never setup a WINS server on any machines and all machines are using 'workgroup' by default. I've tried putting "workgroup" in the Mac's workgroup entry and have tried leaving it blank, neither solves the problem. Here are some things I have tried: Finder-Connect To Server: smb:///share. This works, but by name does not. Terminal-mount_smbfs //@/share share. This also works by ip, but not be name, resulting in "mount_smbfs: server connection failed: No route to host". If I put the IP address of the NAS in the WINS server entry in the Mac's network setup, I can connect by name. It obviously seems to be a name resolution error, but I can't figure out why. The only thing that has changed since it used to work is that I got a new router that now gives out DHCP (all machines are dhcp clients) addresses of 192.168.x.x, but used to be 10.0.x.x. I've grep'd through everything that might have saved that old address, but can't find anything. It's also worth noting that the second Mac (the one that connects successfully) was added to the network after the router change. Please let me know if there are additional points of information needed to troubleshoot this further. Thanks, Randy

  • Changing default datadirectory to one on a External NAS or add external share

    - by Hagbart Celine
    So I have been searching the web for days, looking for a solution to my problem. Now my only hope are you guys. I have installed Owncloud successfully on my Windows Server 2008R2. It all runs smoothly and I can connect without problems. So first checks are OK. Now I wanted to change the default data directory from my server to a shared folder on my NAS (Synology DS1813+, DSM 5.0-4493 Update 3). Tried following: changing the directory in config.php I changed the path in the config file from : "C:\inetpub\wwwroot\myfolder\data" to "\NASIP\cloud". by doing this the owncloud server only shows: Code: Select all Daten-Verzeichnis (\192.168.2.4\Cloud\data) ist ungültig Bitte stelle sicher, dass das Daten-Verzeichnis eine Datei namens ".ocdata" im Wurzelverzeichnis enthält. I also tried coping the files that were created in the local data storage, to the share on the NAS. No Luck. Now I tried it by mapping a network drive and using that in the config.php But still no luck. I get the same message with the missing .ocdata file. Now I tried the "External Storage APP" that comes with owncloud I thought that at least I could add the share as an external storage. But this also does not work. tried UNC, Mapped Drive Name (Z:) but nothing helped. So now I'm turning to you.. Does anyone have expirience with this kind of setup? Or can you even tell me how to make it work? (default or external storgae, I don't care anymore ) Using NAS (Synology DS1813+, DSM 5.0-4493 Update 3), Owncloud 7, Windows Server 2008 R2, IIS7 I got an answer on an other forum: The second option is how it should be done: 1. Put OC in maintenance mode 2. Mount (mapping in the windows world) your NAS directly to your OS 3. Copy the local data directory to the NAS mount 4. Ensure the permission is setup to give the web user access to the NAS mount 5. Update OC config.php with the new data path 6. Disable OC maintenance mode And this seems like the right way.. Ensure the permission is setup to give the web user access to the NAS mount I guess this is where I am not sure. What user is it exactly on my Server that is making the requests to the NAS? If the user is for example "IUSR" I can just create an account on my synology NAS and give him full access to my share? (But what is IUSRs password?) I have full root ssh access to my NAS, so if you can tell me what chmod or chown I need to use on my cloud folder...

  • 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.

  • Intermittently, IIS7 requests get stuck in WindowsAuthenticationModule

    - by Richard Beier
    We're running an IIS7 server hosting several dozen websites. Several of these websites are all part of the same legacy app we've developed. These sites all run the same code and run in the same app pool. Roughly once a month over the past few months, we've found that all requests for this app pool start hanging indefinitely. When this happens, we receive an alert and we recycle the app pool. After that, the sites start working again. This only ever affects this one app pool - never any others on the same server. A couple times, before recycling the pool, I've looked at the currently-executing requests in the worker process. They all show up as executing inside the WindowsAuthenticationModule. Which is strange, because the vast majority of the application does not require authentication. There is a small admin section which uses Windows auth... but all the other requests should be anonymous. Does anyone have any idea as to what might be causing this? There are several unusual things about the way these sites are set up. As I mentioned, they all run the same code - multiple sites point at the same physical directory. The only difference is the host header bindings. I'm not sure why there isn't just one site with all the host headers, but that's how it works. In several of these sites, the same physical directory is mapped at two levels - as the root of the site and again as an application within the site. So if a user goes to http://oursite.com/index.aspx, that maps to c:\files\oursite\index.aspx. If a user goes to http://oursite.com/foo/index.aspx, that also maps to c:\files\oursite\index.aspx. I think there is code which looks at the request URL and handles the two requests differently. This is strange because the same web.config ends up being interpreted as a site config file, and also as an application config file within the site. I don't know if this might be related to the authentication problem. If we can't find the cause, we're thinking of a few workarounds we could try: Move the admin section into a separate site, and give the client a new admin URL. Run that separate site in its own app pool. Then in the web.config shared by all the other sites, remove the WindowsAuthenticationModule. That way there should be no possibility of a hang within the WindowsAuthenticationModule. Try running all these sites in the classic pipeline instead of the integrated pipeline. They were working fine on our old IIS6 server... (If we get desperate) Set up a watchdog script which monitors the sites and auto-recycles the app pool when it detects that requests are getting stuck. What do you think? Thanks for your help, Richard
