  • Small Business Server services will not start, and remote desktop and UAC are broken

    - by Stephen Jennings
    Yesterday I began setting up a server with Windows Small Business Server 2008. All I am configuring it for right now is to be a domain controller and Exchange server. I completed the initial setup of SBS then started looking through different connection options (allowing VPN versus using a TS Gateway). After I rebooted one time, I started having three not-obviously-related issues: First, I could no longer remote desktop into the computer. I ran TCPView and saw that it was no longer listening on port 3389. I checked everything in Terminal Service Configuration but everything shows the computer ought to be allowing connections. Also, when I tried to use anything that required user account control elevation, the UAC dialog never popped up and the program that was waiting just froze. If I try to run "regedit" from the Run box, for example, it never appears. When I run in safe mode which does not run with UAC, I was able to access everything. I didn't want to deal with it, so I turned off UAC and rebooted. Finally, in the Windows SBS Console, there are status indicators for Security, Updates, Backup, and Other Alerts. The first three get stuck saying "Querying". Looking in the computer alerts, I have events showing the following services stopped: Background Intelligent Transfer Service KtmRm for Distributed Transaction Coordinator Distributed Transaction Coordinator Microsoft Exchange Information Store Microsoft Exchange System Attendant Microsoft Exchange Transport Windows Remote Management Update Services Windows Update I figured I must have configured something wrong accidentally and I couldn't find anything using Google explaining what might be the case, so I just decided to format the hard drive and reinstall SBS from scratch. I did this and everything was working last night, but I just turned the machine back on and it is doing the same thing again! On my second install, I did not configure anything except the following (all from SBS Console): Connect to the Internet (set IP and router address) Turn off customer feedback. Set up internet address. Decline to use a Smart Host for email. Added one standard user account. Since this happened again and I was very careful the second time not to configure anything outside of the SBS Console, I feel like there's something else going on. Right now the machine is on an isolated network that does have internet access. My desktop is the only other machine plugged into this network. Any and all help is appreciated (before I tear my hair out!)

  • How to get php mail function to work on Debian “squeeze”?

    - by Neel Kamal
    I have installed Apache and PHP5 on my debian server. Firstly I tried it using sendmail. Here is the step by step procedure that I have tried : Step 1: apt-get install sendmail Step 2: /etc/init.d/apache2 restart But this didn't work. Then I tried using external SMTP . My domain is registered on BigRock.I registerd an email address there [email protected] and it gave me the required credentials. On server I installed sSMTP > apt-get install ssmtp > Configured "/etc/ssmtp/ssmtp.conf" file. In the configuration file I added [email protected] mailhub=smtp.fostergen.com:587 (Here I have doubt. I am not sure what to use here. I tried smtp.fostergen.com:587, smtp.fostergen.com:25,mx1.mailhostbox.com :587,mx1.mailhostbox.com:25. I am still not sure what to use here mailhostbox.com. I used mx1.mailhostbox.com as it was the mx entry for my domain on bigrock Here is the screenshot![screenshot of bigrock's email management tool] ) hostname=vs3204.ams2.alvotec.de (I entered the command hostname -f on my server and got it as result ) FromLineOverride=YES UseSTARTTLS=YES [email protected] AuthPass=password provided during email registration on bigrock > edited /etc/ssmtp/revaliases (added " root:[email protected]:mx1.mailhostbox.com :587 " in the last line) > edited php.ini file (sendmail_path = /usr/sbin/ssmtp -t) > /etc/init.d/apache2 restart But this didn't work. After this I tried eSMTP. Steps Performed : > apt-get install esmtp > edited /etc/esmtprc hostname=smtp.fostergen.com:587 username= [email protected] password: password provide by bigrock mda="/usr/bin/procmail -d %T" > linked eSMTP to the legacy Sendmail path by execting the command "ln -s /usr/bin/esmtp /usr/bin/sendmail" > edited php.ini file (/usr/bin/sendmail -t -i) > /etc/init.d/apache2 restart But this technique also failed. I just want to send email to users through php mail function. Kindly help. Where I am going wrong?

  • Moving from single-site to multi-site Active Directory has broken OWA proxying

    - by messick
    Originally we had the following setup: OfficeExch01 has Mailbox Role and CAS Role OfficeExch01 is in the office. CoLoExch01 had just CAS Role. CoLoExch01 is internet facing and in a CoLo. Three AD domain controllers in the default site. Users could go to https://webmail.whatever.com/owa, get proxyed to OfficeExch01 and everything was great. Well, we recently setup a separate AD site and put a domain controller and the ColoExch01 server in the new site. I also made that remote DC be a Global Catalog. Now, users get the following error: Outlook Web Access is not available. If the problem continues, contact technical support for your organization and tell them the following: There is no Microsoft Exchange Client Access server that has the necessary configuration in the Active Directory site where the mailbox is stored. I also see event 41 errors in the logs: The Client Access server "https://webmail.xxxxxxx.com/owa" attempted to proxy Outlook Web Access traffic for mailbox "/o=XXXXX/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=xxxxxxk". This failed because no Client Access server with an Outlook Web Access virtual directory configured for Kerberos authentication could be found in the Active Directory site of the mailbox. The simplest way to configure an Outlook Web Access virtual directory for Kerberos authentication is to set it to use Integrated Windows authentication by using the Set-OwaVirtualDirectory cmdlet in the Exchange Management Shell, or by using the Exchange Management Console. If you already have a Client Access server deployed in the target Active Directory site with an Outlook Web Access virtual directory configured for Kerberos authentication, the proxying Client Access server may not be finding that target Client Access server because it does not have an internalUrl parameter configured. You can configure the internalUrl parameter for the Outlook Web Access virtual directory on the Client Access server in the target Active Directory site by using the Set-OwaVirtualDirectory cmdlet. Looking this up I see a lot talk about ExternalURL and InternalURL settings. However, everything worked great until we made the new AD site. I also made sure the internal CAS server's /owa virtual directory is set to use Integrated Authentication. Is there something I need to do to allow Exchange to see that I've made these AD changes?

  • Unable to use TweetDeck on Windows due to "Ooops, TweetDeck can't find your data" and "Sorry, Adobe

    - by Matt
    I'm running Adobe AIR 1.5.2 (latest) on Windows 7 (64-bit RTM) and downloaded TweetDeck 0.31.1 (latest). When I run TweetDeck I get the following errors: Ooops, TweetDeck can't find your data and Sorry, Adobe AIR has a problem running on this computer Other AIR applications install and run fine. I've uninstalled both TweetDeck and AIR and reinstalled. Following the uninstalls I've also removed all on-disk references to both TweetDeck and AIR, but no luck. UPDATE: Using Process Monitor I did a trace of Tweetdeck from the moment it launched until the first error occurred. I saw the following information in the output of the trace: 1 5:22:18.6522338 PM TweetDeck.exe 5580 CreateFile D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\??\d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS\TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak NAME INVALID Desired Access: Generic Write, Read Attributes, Disposition: OverwriteIf, Options: Synchronous IO Non-Alert, Non-Directory File, Attributes: N, ShareMode: Read, Write, AllocationSize: 0 In this trace output, Tweetdeck.exe is trying to create the file D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\??\d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS\TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak but the path specified is invalid. When looking at the path you can see that it is indeed an invalid path. First, there’s the “??” portion which doesn’t exist in the file system since the “?” is an invalid character in Windows/NTFS file systems. Additionally, looking at this path, it actually seems to be composed of two parts (is the "??" a delimiter?): Part 1: D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\?? Part 2: d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS \TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak (the problem here is that d:\Use... doesn’t even exist. What seems to be happening here is that Tweetdeck is looking for the user credentials (the “PrivateEncryptedDatak” file) but it’s looking in the wrong place, can’t find the file, and hence the error that Tweetdeck is giving (shown in the screenshot). I'm trying to determine how TweetDeck is getting this path. I searched the contents of all files on my hard disk hoping to find some TweetDeck or Adobe AIR configuration file containing this incorrect path, but I was unable to find anything. UPDATE: See Carl's comment regarding directory junctions and symbolic links under my accepted answer. This ended up being the problem. Edit by Gnoupi: People, the answer section is there to provide an actual ANSWER, not to say you have the same issue. It doesn't help anyone that you have the same problem. Eventually, if you think this is really worth mentioning, put it as a comment under the question. But simply, if what you want to add is not an answer to the question, then don't post it as an answer. This is not a forum, I recommend new users to read the FAQ: http://superuser.com/faq

  • Trouble joining Windows Server 2008 to Domain

    - by Jim R
    When I try to join my new server to my existing domain I get the following error: "An attempt to resolve the DNS name of a DC in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resove DNS names in the target domain." I have tried all of the following already: Successfully pinged the domain controller. Ping the new server from the domain controller by IP address and by DNS name. Ping the DC server from the new server by IP address and by DNS name. Changed the network to DHCP (it was originally static). No joy as static or DHCP. Turned off all firewall settings. Added the domain name to 'hosts' file. Added the server name of the primary domain controller to the 'hosts' file in the new server. Any ideas? Thanks in advance for any help! Jim Update: With help from J. Brian Kelly (Thanks) I have managed to narrow down the problem to a DNS issue. Specifically, UDP/53 packets are being sent (they are seen in Network Monitor), but are not getting to the DNS server. But, I do not yet know why. Update: The quested output from IPCONFIG for the HyperV host and the virtual machine.

  • Any reason not to disable the Windows pagefile given enough physical RAM?

    - by Evgeny
    The question of disabling the Windows pagefile has already been discussed quite a bit, for example here and here and here. People continue to upvote answers that say "you should not disable your pagefile even if you have plenty of RAM", but I have yet to see any concrete, verifiable reasons being given for this advice. As far as I can see, if you never need to read from the pagefile (because you have enough RAM) then performance could only be worse with it enabled due to Windows pre-emptively writing to it. At best, performance would be the same. I can't see how it could possibly be improved by writing data you never need to read. So my question is: Assuming that I have enough physical RAM for everything I do, is there any reason I should not disable the pagefile? Let's say the version of Windows is Windows XP x64 SP2 or Windows Server 2003 x64 SP2 (same thing). If it's different for Windows Server 2008 x64 I'd be interested to hear an answer for that as well. I'm looking for specific, objective reasons from good sources, not just opinions. Something like "here are the benchmarks done with and without a pagefile and the results were better with a pagefile, even with enough RAM" or "according to this MS KB article problem X occurs if you disable the pagefile". So far the only reasons I've seen mentioned are: Even if you think you have enough RAM you might run out. OK, but for the purposes of this question, let's just take it as a given that I have enough. Maybe I only ever read my email and I have 16GB RAM. Or 128GB. Or 1TB. Or whatever - but it's enough for 100% of what I do, 100% of the time. Another way to think of it is: if I have x MB physical RAM and y MB pagefile and I never run out of RAM in that configuration, would I not be better off, performance-wise, with x+y MB physical RAM and no pagefile? Windows is "used to" having a paging file and it might not function as reliably (from Understanding the Impact of RAM on Overall System Performance That's rather vague and I find it hard to believe, given that MS has provided the option to disable the pagefile. Windows knows what it's doing better than you. No - it doesn't know that I won't run more programs or load more data, but I do.

  • Suspend only works once after full power cycle with ASUS P7P55D-E Pro

    - by John Chadwick
    This one is strange. I can't seem to get suspend working more than once per power cycle. When I say "power cycle," I mean the only way to get one proper suspend is to cut power from the power supply and boot back up cold. After the proper suspend, I get a failed suspend, and after all reboots or cold boots until power is cut, suspends fail. I'm using an ASUS P7P55D-E Pro with a Sandy Bridge Core i7, running on Ubuntu Precise repositories and UEFI. I'm running Nouveau from repository (And Gallium3d compiled from git, but that does not come into this since I can avoid OpenGL and it still happens the same way) with a GTX 285 (nv50.) I had to build a custom kernel (3.3) in order for ACPI 5.0 to be supported and make suspend work at all. I compiled it using the latest Ubuntu kernel's config file with the additional entries set to the default options. All packages are up to date. I know these are relatively exotic settings, but I'm hoping maybe I can get some help anyways. The behavior when suspend fails is strange. Upon a proper suspend, all fans turn off and the only led left on, the power led, is blinking. Upon a failed suspend, 1. USB power remains. 2. The power led stays on solid. 3. All fans seem to still be on. 4. I can hear what I believe is the primary harddrive shutting off. 5. Despite USB power remaining, the USB powered keyboard does not respond to anything, and the indicator leds on it shut off. Pressing the power button does nothing, and of course I have not to date found a way to wake it up. When trouble shooting the first round of issues I got with suspend not too long ago, I ended up building a list of modules to disable upon sleeping. Here's my config file for them: In /etc/pm/config.d/01modules: SUSPEND_MODULES="uhci_hd ehci_hd button" All of my other pm configuration files are stock. In case it's any help, here are my relevant BIOS settings. Thanks.

  • Unable to add IPv6 address to sendmail access list

    - by David M. Syzdek
    I am running Sendmail 8.14.4 on Slackware 13.37. I have the following in my /etc/mail/access file and it works without any errors: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite The above configuration also allows me to send an e-mail via IPv6 to a local user on the mail server. However, it does not allow my office to relay via IPv6. I have tried two ways of adding IPv6 networks to my access file. Method 1: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:IPv6:2001:470:b:84a RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite Method 2: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:[IPv6:2001:470:b:84a] RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite However whenever I try using either method 1 or 2, I am unable to relay e-mail messages through the host. /var/log/maillog entry: May 31 11:57:15 freshsalmon sm-mta[25500]: ruleset=check_relay, arg1=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], arg2=IPv6:2001:470:b:84a:223:6cff:fe80:35dc, relay=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], reject=553 5.3.0 RELAY # Net:office Test session from telnet: syzdek@blackenhawk$ telnet -6 freshsalmon.office.example.com 25 Trying 2001:470:b:84a::69...

  • Setting up nginx as proxy to apache; All good, but nginx doesn't serve media

    - by becomingGuru
    I have set it up such that nginx proxies request and sends django requests to apache and serves media itself.

Question: How can I exclude the child processes and only get the parent process (please note however that the processes I want do also have a parent (e.g. bash) that I'm uninterested with)? Using a regexp with grep on how much indentation there is in the ascii tree feels dirty. Is there a better way? Example: The desired output would be something like this. stpe 4222 0.0 0.2 64524 11668 pts/2 S+ 11:01 0:00 | \_ /usr/bin/python /usr/local/bin/gunicorn app_api:app -c app_api.ini.py stpe 5012 0.0 0.2 64512 11656 pts/3 S+ 11:22 0:00 \_ /usr/bin/python /usr/local/bin/gunicorn app_game_api:app -c app_game_api.ini.py This would be easily parseable to be able to automatically find the PIDs in a script that does the HUPing which is the goal.

  • lighttpd: weird behavior on multiple rewrite rule matches

    - by netmikey
    I have a 20-rewrite.conf for my php application looking like this: $HTTP["host"] =~ "www.mydomain.com" { url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/my_app.php" ) } I want to be able to put the webserver in kind of a "maintenance" mode while I update my application from scm. To do this, my idea was to enable an additional rewrite configuration file before this one. The 16-rewrite-maintenance.conf file looks like this: url.rewrite-once += ( "^/(img|css)/.*" => "$0", ".*" => "/maintenance_app.php" ) Now, on the maintenance page, I have a logo that doesn't get loaded. I get a 404 error. Lighttpd debug says the following: 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.300) -- splitting Request-URI 2012-12-13 20:28:06: (response.c.301) Request-URI : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.302) URI-scheme : http 2012-12-13 20:28:06: (response.c.303) URI-authority: localhost 2012-12-13 20:28:06: (response.c.304) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.305) URI-query : 2012-12-13 20:28:06: (response.c.349) -- sanatising URI 2012-12-13 20:28:06: (response.c.350) URI-path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (mod_access.c.135) -- mod_access_uri_handler called 2012-12-13 20:28:06: (response.c.470) -- before doc_root 2012-12-13 20:28:06: (response.c.471) Doc-Root : /www 2012-12-13 20:28:06: (response.c.472) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.473) Path : 2012-12-13 20:28:06: (response.c.521) -- after doc_root 2012-12-13 20:28:06: (response.c.522) Doc-Root : /www 2012-12-13 20:28:06: (response.c.523) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.524) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.541) -- logical -> physical 2012-12-13 20:28:06: (response.c.542) Doc-Root : /www 2012-12-13 20:28:06: (response.c.543) Rel-Path : /img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.544) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.561) -- handling physical path 2012-12-13 20:28:06: (response.c.562) Path : /www/img/content/logo.png, /img/content/logo.png 2012-12-13 20:28:06: (response.c.618) -- file not found 2012-12-13 20:28:06: (response.c.619) Path : /www/img/content/logo.png, /img/content/logo.png Any clue on why lighttpd matches both rules (from my application rewrite config and from my maintenance rewrite config) and concatenates them with a comma - that doesn't seem to make any sense?! Shouldn't it stop after the first match with rewrite-once?

  • Passwordless ssh failed when login using username

    - by Aczire
    I was trying to setup Hadoop and was stumbled on passwordless ssh to localhost. I am getting a password prompt when trying to connect using ssh username@hostname format. But there is no problem connecting to the machine like ssh localhost or ssh hostname.com. Tried ssh-copy-id user@hostname but it did not work. Using CentOS 6.3 as normal user, I neither have root access or am a sudoer so editing any files like sshd_config is not possible (not even cat the sshd_config file contents). I hope the user login is possible since I can do login without password to localhost, right? Please advise, Here is the ssh debug output.

  • Passenger 2.2.4, nginx 0.7.61 and SSL

    - by boompa
    Has anyone had any luck configuring Passenger and nginx with SSL? I've spent hours trying to get this configuration working as I'd like, using what few resources there are out there on the net, and I can't get any of the supposedly forwarded headers to show up in the Rails controller. For example, with a conf file of the following (and multiple variations thereof): server { listen 3000; server_name .example.com; root /Users/website/public; passenger_enabled on; rails_env development; } server { listen 3443; root /Users/website/public; rails_env development; passenger_enabled on; ssl on; #ssl_verify_client on; ssl_certificate /Users/website/ssl/server.crt; ssl_certificate_key /Users/website/ssl/server.key; #ssl_client_certificate /Users/website/ssl/CA.crt; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #proxy_set_header X-SSL-Subject $ssl_client_s_dn; #proxy_set_header X-SSL-Issuer $ssl_client_i_dn; proxy_redirect off; proxy_max_temp_file_size 0; } and Rails code in the controller like this: request.headers.each { |k, v| RAILS_DEFAULT_LOGGER.error "Header #{k} Val #{v}" } other headers appear, but not those set in nginx, e.g.: Header rack.multithread Val false Header REQUEST_URI Val /login/new Header REMOTE_PORT Val 64021 Header rack.multiprocess Val true Header PASSENGER_USE_GLOBAL_QUEUE Val false Header PASSENGER_APP_TYPE Val rails Header SCGI Val 1 Header SERVER_PORT Val 3443 Header HTTP_ACCEPT_CHARSET Val ISO-8859-1,utf-8;q=0.7,*;q=0.7 Header rack.request.query_hash Val Header DOCUMENT_ROOT Val /Users/website/public I've even gone so far as to modify Passenger's abstract_request_handler's main_loop method, i.e., headers, input = parse_request(client) if headers if headers[REQUEST_METHOD] == PING process_ping(headers, input, client) else headers.each { |h,v| log.unknown "abstract_request_handler: #{h} = #{v}" } process_request(headers, input, client) end end only to find that the supposedly added headers do not exist there either: abstract_request_handler: HTTP_KEEP_ALIVE = 300 abstract_request_handler: HTTP_USER_AGENT = Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 abstract_request_handler: PASSENGER_SPAWN_METHOD = smart-lv2 abstract_request_handler: CONTENT_LENGTH = 0 abstract_request_handler: HTTP_IF_NONE_MATCH = "b6e8b9afbc1110ee3bf0c87e119252ad" abstract_request_handler: HTTP_ACCEPT_LANGUAGE = en-us,en;q=0.5 abstract_request_handler: SERVER_PROTOCOL = HTTP/1.1 abstract_request_handler: HTTPS = on abstract_request_handler: REMOTE_ADDR = 127.0.0.1 abstract_request_handler: SERVER_SOFTWARE = nginx/0.7.61 abstract_request_handler: SERVER_ADDR = 127.0.0.1 abstract_request_handler: SCRIPT_NAME = abstract_request_handler: PASSENGER_ENVIRONMENT = development abstract_request_handler: REMOTE_PORT = 64021 abstract_request_handler: REQUEST_URI = /login/new abstract_request_handler: HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.7 abstract_request_handler: SERVER_PORT = 3443 abstract_request_handler: SCGI = 1 abstract_request_handler: PASSENGER_APP_TYPE = rails abstract_request_handler: PASSENGER_USE_GLOBAL_QUEUE = false I'm tired of banging my head against the wall, so I'd truly appreciate any help I can get!

  • 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...

  • Postfix: Relay access denied

    - by Joseph Silvashy
    When I telnet to my server thats running postfix and try to send an email: MAIL FROM:<[email protected]> #=> 250 2.1.0 Ok RCPT TO:<[email protected]> #=> 554 5.7.1 <[email protected]>: Relay access denied I couldn't really find the answer on the site or by looking at other users question/answers, I'm not sure where to start. Ideas? Update So basically looking at the docs: http://www.postfix.org/SMTPD_ACCESS_README.html (section: Getting selective with SMTP access restriction lists), I don't seem to have any of those directives in etc/postfix/main.cf like smtpd_client_restrictions = permit_mynetworks, reject or any of the other ones, so I'm quite confused. But really I'm going to have a rails app connect to the server and send the emails, so I'm not sure how to handle it. Here is what my config file looks like: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = rerecipe-utils alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = $myhostname, localhost.$mydomain, localhost, mail.rerecipe.com, rerecipe.com relayhost = mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all mynetworks = 127.0.0.0/8 204.232.207.0/24 10.177.64.0/19 [::1]/128 [fe80::%eth0]/64 [fe80::%eth1]/64 Something to note is that relayhost is blank, this is the default configuration file that was created when I installed Postfix, when testing to connect with openssl I get this: ~% openssl s_client -connect mail.myhostname.com:25 -starttls smtp CONNECTED(00000003) depth=0 /CN=myhostname verify error:num=18:self signed certificate verify return:1 depth=0 /CN=myhostname verify return:1 --- Certificate chain 0 s:/CN=myhostname i:/CN=myhostname --- Server certificate -----BEGIN CERTIFICATE----- MIIBqTCCARICCQDDxVr+420qvjANBgkqhkiG9w0BAQUFADAZMRcwFQYDVQQDEw5y ZXJlY2lwZS11dGlsczAeFw0xMDEwMTMwNjU1MTVaFw0yMDEwMTAwNjU1MTVaMBkx FzAVBgNVBAMTDnJlcmVjaXBlLXV0aWxzMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCB iQKBgQDODh2w4A1k0qiPNPhkrPj8sfkxpKPTk28AuZhgOEBYBLeHacTKNH0jXxPv P3TyhINijvvdDPzyuPJoTTliR2EHR/nL4DLhr5FzhV+PB4PsIFUER7arx+1sMjz6 5l/Ubu1ppMzW9U0IFNbaPm2AiiGBQRCQN8L0bLUjzVzwoSRMOQIDAQABMA0GCSqG SIb3DQEBBQUAA4GBALi2vvk9TGKJubXYJbU0PKmVmsfzFK35yLqr0keiDBhK2Leg 274sWxEH3ds8mUaRftuFlXb7RYAGNlVyTuMTY3CEcnqIsH7F2McCUTpjMzu/o1mZ O/B21CelKetBd1u79Gkrv2vWyN7Csft6uTx5NIGG2+pGi3r0gX2r0Hbu2K94 -----END CERTIFICATE----- subject=/CN=myhostname issuer=/CN=myhostname --- No client certificate CA names sent --- SSL handshake has read 1203 bytes and written 360 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: 1AA4B8BFAAA85DA9ED4755194C50311670E57C35B8C51F9C2749936DA11918E4 Session-ID-ctx: Master-Key: 9B432F1DE9F3580DCC6208C76F96631DC5A4BC517BDBADD5F514414DCF34AC526C30687B96C5C4742E9583555A118232 Key-Arg : None Start Time: 1292985376 Timeout : 300 (sec) Verify return code: 18 (self signed certificate) --- 250 DSN Oddly enough when I try to send an email from the machine itself it does work: echo test | mail -s "test subject" [email protected]

  • Why does Ubuntu 9.10 hang during boot at "Booting processor 1 APIC 0x1 ip 0x6000"?

    - by BraeburnDev
    I recently installed a new copy of Ubuntu 9.10 (Kernel 2.6.31-14) on to my Hp Pavilion dv6t, so I can setup a Linux development environment. The install went flawlessly and I proceeded with Ubuntu's udate manager's long list of updates (292 in all). I also setup a swap file and activated a Nvidia 185 driver for the Nvidia 260m GPU on the machine. After all this was done I restarted the computer and booted into Ubuntu this time with a newer 2.6.31-19 Kernel which was installed from the update manager. During booth the computer hung at this point: Feb 24 14:23:12 braeburn-laptop kernel: [ 0.013136] Performance Counters: Nehalem/Corei7 events, Intel PMU driver.

Hopefully this is enough information to go on. I should add that I'm still new to configuring and running a Linux OS although I know enough basic command line usage to do software development. This is my attempt to become more familiar with Linux and manage my own system. I'd like to get some insight on the nature of this system hang, what the problem is and how to resolve it. At this point I can scrap the install if I broke something, but my intuition says this is an issue with the kernel recognizing the correct hardware configuration for my system, or perhaps this is an issue with the APIC drivers managing Nehalem's new power management capabilities? Thanks for looking at this issue and providing feed back.

  • Apache works on http and https, SVN only on http

    - by user27880
    I asked a question about this before, and got most of it fixed. If I switch off https redirect and go to http://mydomain.com/svn/test0, I get the authentication window popping up, and I can enter my AD credentials, and bingo. Switching https redirect back on, if I go to http://mydomain.com I am automatically redirected to https, which is what I want, and the 'CerntOS test page' pops up. Perfect. The problem occurs when I want to go to one of my test repos via https. Here is my httpd.conf file, with confidential information suitably hosed... === NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin [email protected] ServerName svn.mycompany.com ErrorLog logs/subversion-error_log CustomLog logs/subversion-access_log common Redirect permanent / https://svn.mycompany.com </VirtualHost> <VirtualHost svn.mycompany.com:443> SSLEngine On SSLCertificateFile /etc/httpd/ssl/wildcard.mycompany.com.crt SSLCertificateKeyFile /etc/httpd/ssl/wildcard.mycompany.com.key SSLCertificateChainFile /etc/httpd/ssl/intermediate.crt ServerName svn.mycompany.com ServerAdmin [email protected] ErrorLog logs/subversion-error_log CustomLog logs/subversion-access_log common <Location /svn> DAV svn SVNParentPath /usr/local/subversion SVNListParentPath off AuthName "Subversion Repositories" # NT Logon Details Require valid-user AuthBasicProvider file ldap AuthType Basic AuthzLDAPAuthoritative off AuthUserFile /etc/httpd/conf/svnpasswd AuthName "Subversion Server II" AuthLDAPURL "ldap://our-pdc:389/OU=Company Name,DC=com,DC=co,DC=uk?sAMAccountName?sub?(objectClass=*)" AuthLDAPBindDN "DOMAIN\subversion" AuthLDAPBindPassword XXXXXXX AuthzSVNAccessFile /etc/httpd/conf/svnaccessfile </Location> </VirtualHost> === Now, in ssl_error_log, I get === ==> /etc/httpd/logs/ssl_error_log <== [Fri Nov 01 16:07:55 2013] [error] [client XXX.XXX.XXX.XXX] File does not exist: /var/www/html/svn === This comes from the DocumentRoot directive further up the httpd.conf file, which of course points to /var/www/html. I know that this location is wrong, but how can I get SVN to serve the repo? I tried an Alias directive as so .. Alias /svn /usr/local/subversion .. but this didn't work. I tried to alter the Location directive. That didn't work either. Can someone help? I sense that this is so close to being solved ... Thanks.

  • Pinning based on origin of a reprepro repository.

    - by Shtééf
    I'm on Ubuntu 10.04, and trying to set up a repository using reprepro. I'd also like the pin everything in that repository to be preferred over anything else, even if packages are older versions. (It will only contain a select set of packages.) However, I cannot seem to get the pinning to work, and believe it has something to do with the repository side of things, rather than the apt configuration on the client. I've taken the following steps to set up my repository Installed a web server (my personal choice here is Cherokee), Created the directory /var/www/apt/, Created the file conf/distributions, like so: Origin: Shteef Label: Shteef Suite: lucid Version: 10.04 Codename: lucid Architectures: i386 amd64 source Components: main Description: My personal repository Ran reprepro export from the /var/www/apt/ directory. Now on any other machine, I can add this (empty) repository over HTTP to my /etc/apt/sources.list, and run apt-get update without any errors: Ign http://archive.lan lucid Release.gpg Ign http://archive.lan/apt/ lucid/main Translation-en_US Get:1 http://archive.lan lucid Release [2,244B] Ign http://archive.lan lucid/main Packages Ign http://archive.lan lucid/main Sources Ign http://archive.lan lucid/main Packages Ign http://archive.lan lucid/main Sources Hit http://archive.lan lucid/main Packages Hit http://archive.lan lucid/main Sources In my case, now I want to use an old version of Asterisk, namely Asterisk 1.4. I rebuilt the asterisk-1:1.4.21.2~dfsg-3ubuntu2.1 package from Ubuntu 9.04 (with some small changes to fix dependencies) and uploaded it to my repository. At this point I can see the new package in aptitude, but it naturally prefers the newer Asterisk 1.6 currently in the Ubuntu 10.04 repositories. To try and fix that, I have created /etc/apt/preferences.d/personal like so: Package: * Pin: release o=Shteef Pin-Priority: 1000 But when I try to install the asterisk package, it will still prefer the 1.6 version over my own 1.4 version. This is what apt-cache policy asterisk shows: asterisk: Installed: (none) Candidate: 1:1.6.2.5-0ubuntu1 Version table: 1:1.6.2.5-0ubuntu1 0 500 http://nl.archive.ubuntu.com/ubuntu/ lucid/universe Packages 1:1.4.21.2~dfsg-3ubuntu2.1shteef1 0 500 http://archive.lan/apt/ lucid/main Packages Clearly, it is not picking up my pin. In fact, when I run just apt-cache policy, I get the following: Package files: 100 /var/lib/dpkg/status release a=now 500 http://archive.lan/apt/ lucid/main Packages origin archive.lan 500 http://security.ubuntu.com/ubuntu/ lucid-security/multiverse Packages release v=10.04,o=Ubuntu,a=lucid-security,n=lucid,l=Ubuntu,c=multiverse origin security.ubuntu.com [...] Unlike Ubuntu's repository, apt doesn't seem to pick up a release-line at all for my own repository. I'm suspecting this is the cause why I can't pin on release o=Shteef in my preferences file. But I can't find any noticable difference between my repository's Release files and Ubuntu's that would cause this. Is there a step I've missed or mistake I've made in setting up my repository?

  • 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.

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

  • How to force Debian to boot new Kernel?

    - by ThE_-_BliZZarD
    I'm running Debian 6, Debian GNU/Linux, with Linux 2.6.32-5-amd64 under Grub2 ( 1.98+20100804-14+squeeze1) on a remote system (no possibility to view the pre-boot messages). I compiled and installed a new kernel, but I can not get it to boot. What I have done: Installed the packages via: dpkg -i linux-headers-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb linux-image-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb This updated the Grub configuration. My /boot/grub/grub.cfg now contains: menuentry 'Debian GNU/Linux, with Linux 3.5.3.20120914-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 3.5.3.20120914-amd64 ...' linux /vmlinuz-3.5.3.20120914-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-3.5.3.20120914-amd64 } menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 2.6.32-5-amd64 ...' linux /vmlinuz-2.6.32-5-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-2.6.32-5-amd64 } I used grub-set-default "Debian GNU/Linux, with Linux 2.6.32-5-amd64" to set the old kernel as default and then grub-reboot "Debian GNU/Linux, with Linux 3.5.3.20120914-amd64" to boot into the new kernel once. After update-grub I rebooted the system, but everytime it comes back up with the old kernel (2.6). I tried setting the new one as default (grub-set-default 0, update-grub, reboot) but, still the old one. The Syslogs contain NO hint whatsoever about trying to boot the new kernel - only the old one. Would there be any hints regarding problems with a kernel? Is there a way to enable debug-logging in grub? What am I doing wrong? How can I force the system to boot the new kernel?

  • Dovecot Virtual Users Not Authenticating

    - by blankabout
    We have a standard Postfix/Dovecot installation working perfectly with real users but cannot work out how to add virtual users, all virtual user login attempts fail with authentication errors. Following are snippets from the configuration files: /etc/postfix/main.cf: virtual_mailbox_domains = virtualexample.com virtual_mailbox_base = /var/spool/vhosts virtual_mailbox_recipients = hash:/etc/postfix/virtual_mailbox_recipients /etc/dovecot/dovecot.conf: !include conf.d/*.conf /etc/dovecot/conf.d/10-auth.conf auth_mechanisms = cram-md5 digest-md5 plain passdb { driver = passwd-file # Path for passwd-file.

There are of course dozens of examples of using virtual users with Dovecot, but all the ones we have found either refer to Dovecot 1.x (we are using 2.x), using only virtual users (we must use real AND virtual users) or want to use a MySQL db, we need to use a text file. Some hints about where we are going wrong would be very much appreciated.

  • High I/O latency with software RAID, LUKS encrypted and LVM partitioned KVM setup

    - by aef
    I found out a performance problems with a Mumble server, which I described in a previous question are caused by an I/O latency problem of unknown origin. As I have no idea what is causing this and how to further debug it, I'm asking for your ideas on the topic. I'm running a Hetzner EX4S root server as KVM hypervisor. The server is running Debian Wheezy Beta 4 and KVM virtualisation is utilized through LibVirt. The server has two different 3TB hard drives as one of the hard drives was replaced after S.M.A.R.T. errors were reported. The first hard disk is a Seagate Barracuda XT ST33000651AS (512 bytes logical, 4096 bytes physical sector size), the other one a Seagate Barracuda 7200.14 (AF) ST3000DM001-9YN166 (512 bytes logical and physical sector size). There are two Linux software RAID1 devices. One for the unencrypted boot partition and one as container for the encrypted rest, using both hard drives. Inside the latter RAID device lies an AES encrypted LUKS container. Inside the LUKS container there is a LVM physical volume. The hypervisor's VFS is split on three logical volumes on the described LVM physical volume: one for /, one for /home and one for swap. Here is a diagram of the block device configuration stack: sda (Physical HDD) - md0 (RAID1) - md1 (RAID1) sdb (Physical HDD) - md0 (RAID1) - md1 (RAID1) md0 (Boot RAID) - ext4 (/boot) md1 (Data RAID) - LUKS container - LVM Physical volume - LVM volume hypervisor-root - LVM volume hypervisor-home - LVM volume hypervisor-swap - … (Virtual machine volumes) The guest systems (virtual machines) are mostly running Debian Wheezy Beta 4 too. We have one additional Ubuntu Precise instance. They get their block devices from the LVM physical volume, too. The volumes are accessed through Virtio drivers in native writethrough mode. The IO scheduler (elevator) on both the hypervisor and the guest system is set to deadline instead of the default cfs as that happened to be the most performant setup according to our bonnie++ test series. The I/O latency problem is experienced not only inside the guest systems but is also affecting services running on the hypervisor system itself. The setup seems complex, but I'm sure that not the basic structure causes the latency problems, as my previous server ran four years with almost the same basic setup, without any of the performance problems. On the old setup the following things were different: Debian Lenny was the OS for both hypervisor and almost all guests Xen software virtualisation (therefore no Virtio, also) no LibVirt management Different hard drives, each 1.5TB in size (one of them was a Seagate Barracuda 7200.11 ST31500341AS, the other one I can't tell anymore) We had no IPv6 connectivity Neither in the hypervisor nor in guests we had noticable I/O latency problems According the the datasheets, the current hard drives and the one of the old machine have an average latency of 4.12ms.
