  • How to map a user to a domain, with Usermin and Postfix?

    - by HappyDeveloper
    What I need is to create a couple of websites, each one with only one user, which is allowed to send mails from any address @ his own domain. Example: Site foo.com would have an user foo, which can send mails from [email protected]. Currently, when the user logins to Usermin, the default 'from' field is example-dns.net (editable) I want it to show an editable field for the user part, and @foo.com (non editable) So how can I do this? Is there some way to automate this?

  • How does one set up API on a locally hosted server...

    - by L33tCh
    I am setting up a personal Wordpress site and want to be able to post to it from other sites... the common request being for my "API Key". When creating a site on Wordpress.com for example, and API key is sent to you by mail, but surely it should be relatively simple, (if not just an address on the local site to point to,) to have one for a personal server (ubuntu server)?

  • How do I troubleshoot an IPsec tunnel (from a cellular router to a public server)?

    - by Hanno Fietz
    I'm new to IPsec and struggling with a setup that might soon be widely used in our operations (provided I do understand it, eventually...). A cellular router (blackbox by netModule, from its log messages it seems to be running Linux and OpenSwan) connects a sensor network on customers' sites with our public server. We need to be able to connect into the local network, so I had the cell provider give me a public IP (a dynamic one). The way their setup works, the public IPs only allow IPsec traffic. I set up OpenSwan on our Ubuntu server (running Jaunty). This is my connection config from /etc/ipsec.conf: conn gprs-field-devices left=my.pub.lic.ip [email protected] #leftsubnet=192.168.1.129/25 right=%any [email protected] #rightsubnet=192.168.1.1/25 #rightnexthop=%defaultroute auto=add On the router, all I have is the Web UI, in which I made the following settings: "Remote endpoint": public IP of server, same as "left" above "Local Network Address": 192.168.1.1 "Local Network Mask": 255.255.255.128 "Remote Network Address": 192.168.1.129 "Remote Network Mask": 255.255.255.128 The pluto process on the server is listening for connections on port 500. It can't open a tunnel, obviously, because it doesn't know at which IP the client is. I set up a passphrase as PSK for @field.econemon.com in /etc/ipsec.secrets and also configured it in the router (which doesn't seem to support certificates). My problem is, nothing happens. The router just says, IPsec is "down". When I copy-paste the IP into ipsec.conf (for "right="), and ask the server to ipsec auto --up gprs-field-devices, it just hangs until I press Ctrl-C. Is there anything wrong with my setup? How can I debug this further? My router gives the following loglines that seem related, but don't tell me anything: Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/hostkey.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: loading secrets from "/etc/ipsec.d/netbox0.secrets" Feb 21 23:08:20 Netbox authpriv.warn pluto[2497]: "netbox00" #1: initiating Main Mode Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: 104 "netbox00" #1: STATE_MAIN_I1: initiate Feb 21 23:08:20 Netbox daemon.err ipsec__plutorun: ...could not start conn "netbox00" Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN Feb 21 23:08:22 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: received and ignored informational message Feb 21 23:08:28 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 0 seconds Feb 21 23:08:40 Netbox user.warn parrot.system_controller[762]: IPSECCTRLR: Tunnel 0 is down for 10 seconds Feb 21 23:08:52 Netbox authpriv.warn pluto[2497]: packet from 188.40.57.4:500: ignoring informational payload, type NO_PROPOSAL_CHOSEN

  • Mercurial not receiving push

    - by Jeffrey04
    I have a mercurial web-frontend (hgwebdir.cgi) installed on a server, and an installation of nginx was installed in front of it as a reverse proxy to the web-frontend as my friend suggested. However, whenever a large changeset is pushed (via a script), it would fail. I found an issue ticket @google-code that describe similar problem, and there is a solution that says (#39) So the server side answer is: don't send the 401 back early. Be as slow/dumb as 'hg serve' and make the hg client send the bundle twice. How do I do that? My current nginx config location /repo/testdomain.com { rewrite ^(.*) http://bpj.kkr.gov.my$1/hgwebdir.cgi; } location /repo/testdomain.com/ { rewrite ^(.*) http://bpj.kkr.gov.my$1hgwebdir.cgi; } location /repo/testdomain.com/hgwebdir.cgi { proxy_pass http://localhost:81/repo/testdomain.com/hgwebdir.cgi; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering on; client_max_body_size 4096M; proxy_read_timeout 30000; proxy_send_timeout 30000; } From the access log we keep seeing 408 entries incoming.ip.address - - [18/Nov/2009:08:29:31 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" incoming.ip.address - - [18/Nov/2009:08:37:14 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" Is there anything else I can do on the server because solving it on the server side is preferable :/ Further Findings Bitbucket seems to have this solved ( Check liquidhg bitbucket project and the Diagnosis wiki page ) on the server side, can't find the config anywhere though :/ What happens next varies depending on your server. Some servers refuse the BODY, simplying closing the pipe from the client and causing Mercurial to fail. Some, like Apache (at least the way I configure it, and that could be part of the problem) and nginx (they way BitBucket.org configures it), accept the BODY, though it may take a few retries. Bottom line: if Mercurial doesn't fail the push, it sends the changeset data at least once to a server that has already told it it lacks credentials (more on this at Blame). Assuming Mercurial is still running, it resends the "unbundle" request and data, this time with authentication. Finally, Apache accepts the data successfully. Nginx, OTOH, at least under BitBucket's configuration, seems to reassemble the previous body (the one that lacked authentication) and somehow keep Mercurial from re-sending the whole body.

  • UCARP: prevent the original master from taking over the VIP when it comes back after failure?

    - by quanta
    Keepalived can do this by combining the nopreempt option and the BACKUP state on the both nodes: Prevent VRRP Master from becoming Master once it has failed Prevent master to fall back to master after failure How about the UCARP?

  • Do proxies really provide anonymity?

    - by Somebody still uses you MS-DOS
    Do web proxies really provide anonymity? I mean, without someone asking for logs in a web proxy server for who/when connected, is it impossible to know who was behind that IP address? I'm asking this because I heard somewhere that some technologies (like "flash") bypass personal IP information for requests or something like that. (I'm a noob in server configuration and concepts like DNS and proxies. Thanks!)

Surprisingly this is happening only for google.com and not other sites.

  • Attach BCC to all emails processed through Windows Server 2008 SMTP relay

    - by Grant H.
    I currently have a relatively complicated application that sends emails via a nightly job through an SMTP server on Windows Server 2008. Is there a way to configure IIS/SMTP to send a copy of every email that's relayed to another email address? Essentially, can I add a BCC on the fly through IIS/SMTP configuration? Because of the complexity of the application, we would prefer to change the behavior this way if it's possible as opposed to making code changes to the application.

  • Establishing a web page bookmarking process - looking for ideas to improve

    - by Matt
    Like many others, I have a process for bookmarking web pages to read later. My requirements for web page bookmarking are: Ability to bookmark pages must be available from all (within reason) platforms - PC/browser, mobile device, etc. Bookmarks must be centrally stored (implicit from #2) so that I can read the bookmarks from anywhere/any device Full text of web pages must be stored Bonus features would be: Bookmarks and page content should be full text searchable Maintain an archive indefinitely Distinguish between what's read vs. unread Bookmarked page content is cleaned up, e.g. ads eliminated, unnecessary html removed, pages better formatted for reading My current process (which addresses most of these requirements) is as follows: I set up a Gmail account with 2 labels, "Bookmarks Unread" and "Bookmarks Read" Gmail filters set up such that depending on the form of the address (using Gmail's '+string' functionality in addresses), the incoming bookmark gets labeled appropriately On each of my browsers/devices, I have an address book entry for [email protected] and [email protected]. If I want to clean up the page content, I use the Readability bookmarklet which does a great job of giving me the essential content only Anywhere I have Firefox, I use the Send Page by Email extension which, with 2 clicks, allows me to send the cleaned-up Readability page URL and content to one of the above email addresses. Where I don't have Firefox (e.g. iPhone or other mobile device) I use the native ability to send the current link via email (most/all apps have them, including the browser, RSS readers, NYTimes, etc.). In most cases (unless it's built into the particular app), this won't include the page body. The process is almost perfect. I've got the central access and ubiquitous access of Gmail as the storage mechanism, full text searchability (due to Gmail, but of course only for the URLs I send from that Firefox extension), a cleaned up page due to Readability, ability to read offline (assuming I use an IMAP client against Gmail) and permanent archiving of content, including what's been read vs. unread. The missing pieces are: The Send Page by Email Firefox extension seems to only send X bytes of a web page. Or some portion. So it limits my full text searchability. Where I don't have Firefox, I can only send the link, so no full text search at all in those cases. Instapaper looks like it meets most of my requirements (and bonus items). The only downside to me (personal preference) is that central storage is based on Instapaper vs. something more broad like Gmail, which as a generalized service and with Google behind it pretty much means it's permanent. I'm not too hung up on this, but I would definitely prefer to keep Gmail if possible. An upside of Instapaper is that it does the page clean-up as well as stores the entire page content, unlike my Firefox extension. Thoughts on addressing the gaps and improving this process further?

  • Recognizing Dell EquilLogic with Nagios

    - by user3677595
    EDIT: All firmware and models are compatible, that is why nothing is posted about it. Okay, so there will be a lot here, so please bare with me. I've been working on this now for a few hours (reading manuals and such) so I'm not just coming here right out of the blue. I am working on a PRE-EXISTING Nagios server where there are several other existing plugins and checks running and working. Now I want to add another server there to check so I made the following modifications: First and foremost, I added a file to /usr/local/nagios/libexec named: check_equallogic.sh. The permissions are 755, the same as all others. I have chowned to nagios:nagios and in the listing it shows the Owner as Nagios. I then added a command to the commands.cfg file in \usr\local\nagios\etc\objects that shows the following: # 'check_equallogic' command definition define command{ command_name check_equallogic command_line $USER1$/check_equallogic -H $HOSTADDRESS$ -C $ARG1$ -t $ARG2$ $ARG3$ } Following this, I created a file named equallogic.cfg in the objects directory and it contains (more or less): define host{ use linux-server ; Inherit default values from a template host_name 172.16.50.11 ; The name we're giving to this device alias EqualLogic ; A longer name associated with the device address 172.16.50.11 ; IP address of the device contact_groups admins } Check Equallogic Information define service{ use generic-service host_name 172.16.50.11 service_description General Information check_command check_equallogic!public!info } After ensuring that permissions are okay for all files, I restart the nagios service, no errors. When I go into the WebGUI, I get the following errors AFTER the check runs: (Return code of 127 is out of bounds - plugin may be missing) Extra, probably unrelated problem Furthermore, when I log into the EquilLogic server, under Audit logs I get the following error: Level: AUDIT Time: 26/05/2014 3:59:13 PM Member: ps4100-1 Subsystem: agent Event ID: 22.7.1 SNMP packet validation failed, request received from 172.16.10.11 An snmpwalk receives a timeout, whereas others succeed. I will work on importing the MIBs tomorrow. The reason why I am mentioning it is because I want to make sure that it is only a MIB issue for the SNMP. If it is, then ignore this area. I am entirely unsure of what to do here.

  • Router reporting failed admin login attempts from home server
