• Is there a way to force spam-filter to change their policy or remove them as recognized spam service?

  - by Alvin Caseria

  As per mxtoolbox I got 1 blacklist still active for quite sometime now. UCEPROTECTL1's is running on 7 day policy since last spam mail. This is too strict compared to the 98 other spam filters out there as per mxtoolbox. (Or at least to the other 4 that detected the problem) I have no problem with our e-mail since it is hosted locally. But our domain is hosted outside the country and it run on a different IP. I contacted them but since it is the spam-filter's rule, there's nothing to be done but wait. I do believe services like spam-filters should at lease be bounded by guidelines and standards for this matter. Otherwise problem on delivering valid (after the fix) e-mails will be disastrous. Is there a way to force UCEPROTECT to change their policy or remove them as recognized spam service? Apart from contacting them in case they do not answer. Currently they are charging for fast removal if you pay by PayPal. I'm still looking for guideline/standard on how they should operate regarding this matter. Appreciate the help.

• VMware ARP/Mac Networking

  - by Ross Wilson

  Hi Guys, I am very interested in how VMware networking works. I have scoured the VMware website and read their data sheets, this has given me some basic knowledge. I now have some questions. Lets assume that we have a physical server running the VMware hypervisor. The physical server is running a Virtual Machine. The physical box has one physical NIC. The NIC is connected to a switch, as so is a desktop client. Now, this is where my first question lies. The VM has an IP address: 192.168.1.1. How do desktop clients on the network communicate with this VM? So, the client pings 192.168.1.1. The ping packet is sent to the switch. The switch checks its MAC address table and sees that 192.168.1.1 is associated with the MAC address of the physical NIC. Correct? I then assume that the ping packet is sent to the server's physical NIC, where the hypervisor routes the packet to the VM thats using 192.168.1.1? Please could you give me a run down as to how VM networking works? Many thanks, Ross

• Vyatta masquerade out bridge interface

  - by miquella

  We have set up a Vyatta Core 6.1 gateway on our network with three interfaces: eth0 - 1.1.1.1 - public gateway/router IP (to public upstream router) eth1 - 2.2.2.1/24 - public subnet (connected to a second firewall 2.2.2.2) eth2 - 10.10.0.1/24 - private subnet Our ISP provided the 1.1.1.1 address for us to use as our gateway. The 2.2.2.1 address is so the other firewall (2.2.2.2) can communicate to this gateway which then routes the traffic out through the eth0 interface. Here is our current configuration: interfaces { bridge br100 { address 2.2.2.1/24 } ethernet eth0 { address 1.1.1.1/30 vif 100 { bridge-group { bridge br100 } } } ethernet eth1 { bridge-group { bridge br100 } } ethernet eth2 { address 10.10.0.1/24 } loopback lo { } } service { nat { rule 100 { outbound-interface eth0 source { address 10.10.0.1/24 } type masquerade } } } With this configuration, it routes everything, but the source address after masquerading is 1.1.1.1, which is correct, because that's the interface it's bound to. But because of some of our requirements here, we need it to source from the 2.2.2.1 address instead (what's the point of paying for a class C public subnet if the only address we can send from is our gateway!?). I've tried binding to br100 instead of eth0, but it doesn't seem to route anything if I do that. I imagine I'm just missing something simple. Any thoughts?

• Nexus functionality is limited after installation

  - by Dmitriy Sukharev

  I have a CentOS based server with Sonatype Nexus 2.0.4-1 installed. The issue is that there are no standard "Artifact Search", "Advanced Search", "Browse Index", "Refresh Index" Nexus features, as well as Artifact Information tab after selection of any artifact (only Maven Information tab). I tried to Google, but was amazed that there're no information about this issue. Actually it looks like all actions I've done are: wget http://www.sonatype.org/downloads/nexus-2.0.4-1-bundle.tar.gz tar -xvf nexus-2.0.4-1-bundle.tar.gz cp -r nexus-2.0.4-1 sonatype-work /opt/ ln -s /opt/nexus-2.0.4-1/* /opt/nexus ln /opt/nexus/bin/nexus /etc/init.d/ chmod 755 /etc/init.d/nexus vim /etc/init.d/nexus NEXUS_HOME=“/opt/nexus” RUN_AS_USER=“nexus” useradd -s /sbin/nologin -d /var/lib/nexus nexus chown -R nexus /opt/nexus/ chown -R nexus /opt/nexus-2.0.4-1/ sudo -u nexus cp /opt/nexus/conf/examples/proxy-https/jetty.xml /opt/nexus/conf/ To force Nexus be available through HTTPS I went to Administration - Server - Application Server Settings as admin and changed Base URL to https:// external IP/nexus and set Force Base URL to true. Any ideas how to get missed Nexus features?

• DNS Does Not Register at Off-site Locations

  - by Russ Warren

  First of all, let me give you the specifics of our setup: Windows Small Business Server 2008 Domain w/ all applicable updates on the DC The DC does DHCP for the main site The DC does DNS for all sites 3 sites including our headquarters where the DC is located All sites are connected through OpenVPN SSL tunnels terminated by an Untangle box at each site The 2 remote sites us the Untangle box as a DHCP server for their subnet, which assigns the DC as the primary DNS server Collection of Windows XP and Windows 7 workstations connected to the domain Here's the issue: All of the workstations at the main site register with the DNS server on the domain controller fine. As they grab an IP from the DHCP server, it updates the DNS server with the new host record. I have 2 systems (each at different remote sites) that fail to register with the DNS server. I've attempted the following troubleshooting steps: Confirmed the network adapter is using the DC as a DNS server Confirmed 2-way traffic is possible between DC and workstation Verified the "Register with DNS server" setting was checked in the adapter properties Attempted ipconfig /registerdns and received no errors For the time being, I have setup a DHCP reservation for these systems and manually created a host record. This seems to work fine, but I need a solution for any new systems that go out there.

• Access Denied / Server 2008 / Home Directories

  - by Shaun Murphy

  Domain Controller: BDC01 (192.168.9.2) Storage Server: BrightonSAN1 (192.168.9.3) Domain: brighton.local Last night I moved our users home directories off of our Domain Controller onto a storage server using the MS FSMT. I'm getting a mixed bag of errors. The first being some users cannot logon properly, they can't access the logon.vbs in the sysvol folder on the DC and consequently cannot map their drives. I've narrowed that down to a DNS issue as we there was a remnant of our previous DNS server in the DHCP server options and scope options. I'm able to get their drives remapped by browsing to the sysvol folder by IP address as opposed to Computer Name and manually running the logon.vbs script. The other error I'm getting is Access Denied on a few of the users home directories. The top level folder (Home) is shared as normal and I've removed and re-added the NTFS security a number of times now including making the user the owner with full control. I've checked each and every individual file and folder in said users home directory and they are indeed the owner but I'm unable to write but I can read the contents. I'm stumped. This isn't happening to all clients. I'm considering removing their AD accounts, backing up their folders and readding them as a last resort but obviously I'd like to know why the above errors are happening.

• Apache Reverse proxy for intranet and other integrated application on intranet

  - by user1433448

  I'm trying to configure a reverse proxy (ssl) with apache 2.2 in Debian Squeeze, but I have some problems, specially with some path absolute and with https I'll try to detail what I have made and what I'm trying to configure I have a server Debian Squeeze with apache2.2 + mod_proxy_html with: # apt-get install libapache2-mod-proxy-html libxml2-dev # a2enmod proxy # a2enmod proxy_http # a2enmod proxy_html # a2enmod headers After that I have configured a virtual host with: reverse_proxy_ssl.conf I'm trying to configure to allow access of our intranet from internet with a reverse proxy (apache that is located in DMZ). With this configuration domain.com/intranet works correctly and we can access to intranet, but we have one problem when from domain.com/intranet we need to use another internal application that is called from intranet with absolute path ( https://192.168.10.25/application/) and from internet appears that try to access with internal ip, and this link es incorrect from external site We only need to access from intranet to multiple internal application that are in external server and we like to restrict to minimal access from internet. All the application that are in the smae server of intranet are working. The second problem is with https and reverse proxy in our firewall appears some errors with packets (not valid packets), and with https seems to work. What can I do to solve this problems (absolute path and ssl problem) Thanks

• JavaScript is not pointing correctly on IIS7 running behind Apache mod_proxy

  - by sohum

  So here's my setup. I've got a DynDNS account since I have a dynamic IP. I have Apache listening on port 80 and IIS7 on port 8080. I don't want users to have to enter in mydyndns.dyndns.com:8080 to get to IIS7, so I've added the following code to my Apache httpd.conf file to enable a proxy/reverse proxy: <VirtualHost *:80> ProxyPass / http://localhost:8080/myASPSite/ ProxyPassReverse / http://localhost:8080/myASPSite/ ServerName myaspsite.mydomain.com </VirtualHost> I've got a CNAME record set up on my DNS so that myaspsite.mydomain.com redirects to mydyndns.dyndns.com. When I type in myaspsite.mydomain.com into my browser, everything works beautifully... mostly. IIS7 serves up the ASPX pages and visitors to the site don't know any better. A problem arises, however, when I add Ajax Control Toolkit controls into my ASPX website, because these generate JavaScript and apparently mod_proxy_html isn't geared to handle the JS URIs properly. Sure enough, when I open up the source of my ASPX page, it has script elements as follows: <script src="/myASPSite/WebResource.axd?xyz" type="text/javascript"></script> <script src="/myASPSite/ScriptResource.axd?xyz" type="text/javascript"></script> Sure enough, these scripts are attempting to be resolved at http://myaspsite.mydomain.com/myASPSite/WebResource..., which through the proxy translates to localhost:8080/myASPSite/myASPSite/.... How can I solve this problem. The couple of websites I found suggested turning on ProxyHTMLExtended but when I tried doing that, the server did not start. I'm guessing I didn't know how to do it properly. Anyone has a handy couple of config lines that I can add to my Apache conf file to get this working as I need? I'm using Apache 2.2.11. Thanks!

• Installation of Active Directory on separate VM from DNS does not entierly work - not sure why

  - by René Kåbis

  Not sure what I am doing wrong here. I have a moderately midrange server (16 cores, 2Ghz, 32GB ECC REG RAM, 6TB storage, nothing too extreme) where I am running Hyper-V (Server 2012 R2 Enterprise) in order to provision virtual machines. So why an AD separate from DNS? I want redundancy. I want to be able to move VMs and back them up individually and not have too many services on any one VM. I have already provisioned a VM with DNS, and have set it up right -- essentially, I have: Set up Static IP’s for everyone involved. Installed the DNS service on the DNS VM. Created a forward lookup zone and a reverse lookup zone (primary zone) xyz.ca Configured the zones to use nonsecure and secure dynamic updates (i will change this to secure later after the domain controller is online). Created a A record for the DC in the forward lookup zone (and a reverse ptr) Changed DC’s DNS server (network settings) to the new DNS server. Checked that I can ping the dns server from the new DC by hostname. When I went ahead and did a DCpromo on the DC, and un-cheked the “install DNS” option, everything seemed to go well (no error messages), but I saw no changes on the DNS server whatsoever (no additional settings). Plus, the DNS server seems to be unable to join the domain, as it claims that the domain is not discoverable. As a final note, I do run Symantec Endpoint Protection, which includes a firewall and most settings set as default. I have not yet tried turning this off, but my experience has been that if a service would open up a port on a Windows firewall, it would do the same through Symantec. There is pretty tight integration these days with corporate-class AV and Windows. I have a template vhdx fully set up (just short of any special roles and features) that I can use to replace the current AD VM with, so doing this all over again is not too much skin off of my nose.

• With WebMatrix, How do I Connect to a MySQL Database on a Colleague's Machine?

  - by Ash Clarke

  I have scoured Google trying to discover how to do this, but essentially I want to connect to a colleague's MySQL database for working together on a Wordpress installation. I am having no luck and keep getting an error about the connection not being possible: Unable to connect to any of the specified MySQL hosts. MySql.Data.MySqlClient.MySqlException (0x80004005): Unable to connect to any of the specified MySQL hosts. at MySql.Data.MySqlClient.NativeDriver.Open() at MySql.Data.MySqlClient.Driver.Open() at MySql.Data.MySqlClient.Driver.Create(MySqlConnectionStringBuilder settings) at MySql.Data.MySqlClient.MySqlPool.GetPooledConnection() at MySql.Data.MySqlClient.MySqlPool.TryToGetDriver() at MySql.Data.MySqlClient.MySqlPool.GetConnection() at MySql.Data.MySqlClient.MySqlConnection.Open() at Microsoft.WebMatrix.DatabaseManager.MySqlDatabase.MySqlDatabaseProvider.TestConnection(String connectionString) at Microsoft.WebMatrix.DatabaseManager.IisDbManagerModuleService.TestConnection(DatabaseConnection databaseConnection, String configPathState) at Microsoft.WebMatrix.DatabaseManager.Client.ClientConnection.Test(ManagementConfigurationPath configPath) at Microsoft.WebMatrix.DatabaseManager.Client.DatabaseHierarchyInfo.EnsureLoaded() The connection details are copied from my colleague's connection string, with the exception of the server being modified to match the IP address of his machine. I'm not sure if there is a firewall port I have to open or a configuration file I have to modify, but I'm not having much luck so far. (There is a strong chance that, by default, web matrix / iis express doesn't set the mysql database it creates to accept remote connections. If anyone knows how to change this, that would be grand!) Anyone have any ideas?

• Connect over WiFi to SQL Server from another computer

  - by Bronzato

  I tried to connect over WiFi to SQL Server with SQL Server Management Studio from another computer, but it failed. I have a computer with Windows 7 & SQL Server 2008 (lets say the server computer). Next to it I have a freshly installed computer with Windows 7 & SQL Server Management Studio (let's say the client computer). What I did on the server computer: Configure firewall by enabling port 1433 Enabled network protocols (TCP/IP) inside SQL Server Configuration Manager Checked Allow remote connections to this server in server properties in the SQL Server Management application. Started SQL Server Browser Restarted services (SQL Server Browser is stopped at this point, but I don't think it is necessary. Is it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to SQL Server on my server computer. Ok, something new with this problem: Until now, I successfully connected to my "server computer" with Management Studio. What I did is type the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of SQL server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name. Now my new challenge is to be successful in connecting my VB6 application to this remote database located on my "server computer". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's going wrong?

• Providing access to a Samba server for VPN clients

  - by Kamil Kisiel

  We have some Windows users that connect to our network via VPN from home. They need to be able to connect to our Samba server and access a mapped network drive just as they do as when they are on our LAN. The complication is that VPN clients are placed on a subnet other than our office LAN, and behind a firewall. What's the easiest way for me to allow them to still connect to the network share? The solutions I've currently seen involve setting up a WINS server for name resolution purposes and then tunnelling a bunch of the NetBIOS stuff through the firewall. However that means I'd have to set up the VPN DHCP server to hand out the WINS address, something I'm not even sure is possible on the Cisco hardware we have. I'm thinking there must be an easier way. Should I use an LMHOSTS file? Or just map by IP address? Also, I'm not terribly familiar with Windows networking, so which ports would I need to pass through my firewall in order to get the file sharing through?

• rsync over ssh backup failing after relocation of server

  - by OlduvaiHand

  I've got two FreeBSD machines set up; one serves video data and the other is the backup for the first. At this point I've got around 4TB of data. I add files to the video server a few at a time, and was planning to use rsync over ssh to keep the backup machine up to date. I did the initial, large backup with both machines hooked up to the same subnet at the lab with no problems using rsync. Then, when I moved the backup machine off-site (but still on the university network), I attempted a sync without changing anything other than the IP (as the machine is now on a different subnet) and got the following error: 2010/03/22 15:55:21 [1260] rsync: connection unexpectedly closed (6340840244 bytes received so far) [receiver] 2010/03/22 15:55:21 [1260] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [receiver=3.0.7] 2010/03/22 15:55:21 [1258] rsync: connection unexpectedly closed (60 bytes received so far) [generator] 2010/03/22 15:55:21 [1258] rsync error: unexplained error (code 255) at io.c(601) [generator=3.0.7] The script that handles the backup hasn't been changed, nor has the crontab that invokes it. Does anyone have any ideas about what might be causing the hiccup? I was under the impression that it might have something to do with the ssh connection timing out or something along those lines, but am not entirely clear on how to diagnose the cause of the problem.

• How to set up QoS on ADSL router (terracom) for prioritizing browsing

  - by DBZ_A

  I want to configure the ADSL router which connects 10+ machines to the internet. I want to give maximum priority to browsing (ports 80,443) and set low priority for bittorrent etc.(port 42180) I have been experimenting with settings , but with no luck. There are three settings which confuse me, along with my understanding. 802.1 Priority - Related to LAN level, possible values 0-7 , higher numbers means higher priority. 'Mark traffic priority' - clueless about this. IPP/DS - IP Precedence - possible values 0-7 ; 6 & 7 are reserved, so set 5 for highest priority. Or when using DSCP - set 46 for highest priority. Please help me in getting this done... Similer question for another model of router here , but with less number of confusing options :) How to configure QoS on home router Update: from discussion on another thread, QoS can control only upstream traffic (from router to the internet) , while this may in turn affect downstream traffic rate, there is no direct control over data coming into the router.

• Can't get simple Apache VHost up and running

  - by TK Kocheran

  Unfortunately, I can't seem to get a simple Apache VHost online. I used to simply have one VHost which bound to all: <VirtualHost *:80>, but this isn't appropriate for security anymore. I need to have one VHost for localhost requests (ie my dev server) and one for incoming requests via my domain name. Here's my new VHost: NameVirtualHost domain1.com <VirtualHost domain1.com:80> DocumentRoot /var/www ServerName domain1.com </VirtualHost> <VirtualHost domain2.com:80> DocumentRoot /var/www ServerName domain2.com </VirtualHost> After I restart my server, I see the following errors in my log: [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs What am I doing wrong?

• Is there a small business router that shows bandwidth usage graphs in the admin panel?

  - by Robert Drake

  I support a large number of public libraries that are having their networks upgraded in response to a grant application. These libraries are generally home to between 6-15 computers and have little or no tech services either onsite or contracted remotely. In order to justify current and future purchases, a number of the libraries have requested routers that can provide bandwidth usage graphs that they can show to their managing boards. Is there a small business router that displays traffic graphs in the router administration web interface? The router needs to suppport DHCP and basic firewalling. No other features are required. Further, the reports just need to show overall trends. It is not necessary to show traffic by IP, by protocol/application, or by time of day. They just need an overall week to week, month to month, trend line. I'm familiar with MRTG/PRTG/tools that collect SNMP data from the router, but the libraries don't have the expertise for the configuration. I've considered installing the tomato firmware on some cheap home/home office routers, but if there's a commercial product that can be purchased that would be significantly simpler. Also the library boards would be much more likely to approve the purchase of a commercial product over a 'hacked' one. Any assistance would be appreciated.

• 1 document pending in printer queue in System Tray that won't go away

  - by White Phoenix

  Edit: I didn't want to do it, but I restarted my computer - cleared the problem right away. Though if I were running a Windows 2003/2008 server, I would hate to have to restart the domain controller just to get rid of this irritating problem. If I run into this problem again, I'm going to try that remove printer/reinstall printer thing. Thanks for your help @Psychogeek. Points for your attempt. Running Windows 7, 32-bit Professional. My printer is an HP OfficeJet Wireless 8500. It's connected to my network wirelessly through TCP/IP as a standalone device. I was having some print problems awhile back and had to do some print spooler stuff as part of my troubleshooting (stopping the Print Spooler service, clearing the print spooler files from C:\Windows\System32\spool\PRINTERS and then restarting the service). I've finally narrowed it down to it being application specific, so that's that. However, as a leftover from all that troubleshooting, my printer icon is stuck in the tray - when I mouseover the icon, Windows says that there is 1 document(s) pending for my username. However, when I open up that printer's queue, there's nothing in there. I restarted the Printer Spooler service and also checked C:\Windows\System32\spool\PRINTERS if there's anything in there - nothing. I did a quick Google search and an answer from one of those "reps" at the Microsoft Socialnet site says for me to uninstall and reinstall the printer. The funny thing is, when I send print jobs, they print just fine - that 1 mystery document stuck in queue isn't stopping anything from happening. Short of having to do that, are there any other quick troubleshooting steps I may be missing?

• apache name virtual host - two domains and SSL

  - by Tom

  I'm trying to setup Apache(2.2.3) to run two websites with SSL using both different domains and IP addresses. Both websites run fine on port 80 but when I tried to enable SSL for website2 I get a ssl_error_bad_cert_domain error; website2 picks up the SSL cert for website1.

  My bugzilla system keep hit the following error: There was an error sending mail from '[email protected]' to '[email protected]':Can't send data I think that is some problem with my setting and configuration. First is the urlbase I have tried setting it to bugzilla.example.com, and http://127.0.0.1:81/, and http://10.0.0.236/ (My laptop IP address, I use this laptop to set up bugzilla) but the error still persists.

• Setting up 802.1X wireless connection on OSX

  - by hizki

  I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort (version 5.5.2). I am trying to connect to my university's wireless network, but it has a 802.1x security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my Mac? I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort (to version 5.5.2) it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password. Update: I have already tried to create a new "location", removed all the 802.1x user profiles and all the remembered networks, and made sure the in the TCP/IP tab 'Configure IPv4' is set to "Using DHCP". I also moved /Library/Preferences/SystemConfiguration/preferences.plist to my desktop in attempt to force the system to create a new set of settings. Still I can define the connection to work.

• Why can't I unblock postgres with shorewall?

  - by ryeguy

  I can't seem to unblock the port needed for postgres using Shorewall. I am developing a PHP app on my windows machine here, and then I upload it on my linux box to actually use it. The linux box runs the php files as well as hosts the db server. Since I need it working from both machines, in my PHP code I am referring to the database as the full IP instead of localhost. I can easily connect to postgres from my windows machine, but ironically, my PHP app can't connect to postgres even though it's on the same box. Here's what I have in /etc/shorewall/rules: #macro/action src dest PostgreSQL/ACCEPT net $FW PostgreSQL/ACCEPT loc $FW PostgreSQL/ACCEPT loc dmz PostgreSQL/ACCEPT net dmz PostgreSQL/ACCEPT loc net PostgreSQL/ACCEPT dmz $FW PostgreSQL/ACCEPT dmz loc PostgreSQL/ACCEPT dmz net PostgreSQL/ACCEPT dmz dmz Clearly I have a ton of crap there. The first line is all I needed to make it allow a connection from my windows machine. All the lines after it are me just trying everything to get it to work. What am I missing?

• New XPC: No video, no ethernet link, but drive spins

  - by Mike Pennington

  I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

• duplicity fail: not promping for password: "Running 'sftp user@host' failed"

  - by Thr4wn

  I have two linode VPS accounts and I want to back up one onto the other (the reasons are mainly for fun and to practice server administration.) the short version Duplicity isn't even asking for my password, but immediately says "invalid SSH password" (but I can ssh into the other server). why? the long version When I run duplicity /home/me scp://[email protected]//root/backup I get Invalid SSH password Running 'sftp [email protected]' failed (attempt #1) Invalid SSH password Running 'sftp [email protected]' failed (attempt #2) Invalid SSH password Running 'sftp [email protected]' failed (attempt #3) And it says Invalid SSH password immediately with no opportunity for me to actually type the password. When I type duplicity full -v9 --num-retries 4 /home/me scp://[email protected]//root/backup I get Main action: full Running 'sftp [email protected]' (attempt #1) State = sftp, Before = 'Connecting to 97.107.129.67... [email protected]'s' State = sftp, Before = '' Invalid SSH password Running 'sftp [email protected]' failed (attempt #1) I can ssh into [email protected] fine, and in fact have the ip in known_hosts before I tried any of this. serer 1 (from which I'm running the duplicity command) is Linode's default Ubuntu 8 setup with only a handful of programs installed via apt-get. server 2 (represented by x.x.x.x) is literally only Linode's default Ubuntu 8 setup I previously tried using SystemImager -- would that have changed settings in a destructive way? (I have removed and rebooted since then) Isn't Duplicity supposed to prompt for password? Am I using it wrong? are there common mistakes/dependencies I need to know about? Is there any way that x.x.x.x could be setup that could make this not work (I used Linode's default Ubuntu 8 setup and barely )?

• Fixing Poor Email

  - by Tiffany Walker

  I'm having an issue with SenderBase. My IPs are not blocked in any BLs but people who use SenderBase/Ciscos stuff do not get my emails. Is this because my email system is setup poorly? They list the following: Your email server or a computer in your network may be infected with malware and may be used to send spam. You may have an insecure network which is allowing other parties to use your network to send spam. Your email server may be misconfigured and might relay spam. You may be utilizing a dynamic IP that is not allowed to relay email directly to the Internet. I have just my site running CPanel. As far as I know there is no spam or abuse. What should I check to ensure that the mail systems (Exim) are up to standards? I have the server pretty well configured so I just can't see the system being abused without me knowing it. What standards should I be ensuring my e-mail server aligns up to?

• hadoop: port appears open locally but not remotelly

  - by miguel

  I am new to linux and hadoop and I am having the same issue as in this question. I think I understand what is causing it but I don't know how to solve it (Don't know what they mean by "Edit the Hadoop server's configuration file so that it includes its NIC's address."). The other post that they link says that the configuration files should refer to the machine's externally accessible host name. I think I got this right as every hadoop configuration file refers to "master" and the etc/hosts file lists the master by its private IP address. How can I solve this? Edit: I have 5 nodes: master, slavec, slaved, slavee and slavef all running debian. This is the hosts file in master: 127.0.0.1 master 10.0.1.201 slavec 10.0.1.202 slaved 10.0.1.203 slavee 10.0.1.204 slavef this is the hosts file in slavec (it looks similar in the other slaves): 10.0.1.200 master 127.0.0.1 slavec 10.0.1.202 slaved 10.0.1.203 slavee 10.0.1.204 slavef the masters file in master: master the slaves file in master: master slavec slaved slavee slavef the masters and slaves file in slavex has only one line: slavex
