  • best way to import mailing list archives

    - by Naveen Garg
    I tried reading mailing lists in gnus in emacs, but emacs stops responding with the slow nntp servers downloads. nabble, gmane etc are also kind of slow. So I thought about download the gzipped archives available from most mailing lists. here are some nice instructions to import these archives into thunderbird. Is there a similar streamlined way to read the unziped archives in emacs, or other software ?

  • Taskbar on secondary monitor in XP?

    - by Hemal Pandya
    I am looking for a free virtual-desktop program that will allow me to put a different virtual desktop on each of my two monitors (one on laptop and the other external) How I would like to use it: I do a lot of work connecting to other servers using remote desktop. I would like to use the external monitor to open remote desktop in full screen and use the laptop monitor for the local machine to view my mails, chat, browser, etc. I am using XP SP3.

  • Do I really need mod_security?

    - by Rob
    I'm doing a clean install of my server and I'm looking for some advice on whether or not I actually need the Apache mod_security module. I consider myself to be a bit security paranoid when it comes to my servers, but is it worth going through all the hassle to install and debug a new config of mod_security?

  • Samba with Active Directory - shares are readonly, NT_STATUS_MEDIA_WRITE_PROTECTED

    - by froh42
    I've set a samba server that seems to work, all shares are seemingly exported as readonly, however. The machine is called "lx". When I'm on lx I can run the following command: froh@lx:~$ smbclient //lx/export -UAdministrator Enter Administrator's password: Domain=[CUSTOMER] OS=[Unix] Server=[Samba 3.5.4] smb: \> mkdir wrzlbrmpf NT_STATUS_MEDIA_WRITE_PROTECTED making remote directory \wrzlbrmpf smb: \> ls . D 0 Fri Dec 3 19:04:20 2010 .. D 0 Sun Nov 28 01:32:37 2010 zork D 0 Fri Dec 3 18:53:33 2010 bar D 0 Sun Nov 28 23:52:43 2010 ork 1 Fri Dec 3 18:53:02 2010 foo 1 Sun Nov 28 23:52:41 2010 gaga D 0 Fri Dec 3 19:04:20 2010 How can I troubleshoot this? What I did: First I set up a fresh install of Ubuntu 10.10 x64. Second I got kerberos working with the following krb5.conf file: [libdefaults] ticket_lifetime = 24000 clock_skew = 300 default_realm = CUSTOMER.LOCAL [realms] CUSTOMER.LOCAL = { kdc = SB4.customer.local:88 admin_server = SB4.customer.local:464 default_domain = CUSTOMER.LOCAL } [domain_realm] .customer.local = CUSTOMER.LOCAL customer.local = CUSTOMER.LOCAL #[login] # krb4_convert = true # krb4_get_tickets = false I also added winbind to group, passwd and shadow in nsswitch.conf. Seemingly Kerberos works: root@lx:~# net ads testjoin Join is OK root@lx:~# wbinfo -a 'Administrator%MYSECRETPASSWORD' plaintext password authentication succeeded challenge/response password authentication succeeded wbinfo -u and wbinfo -g also spit out a list of users and a list of groups respectiveley. I noted that domain accounts did NOT include a domain and they are in german (as on the SBS 2003 that is the domain server). So I get a "Domänenbenutzer" in wbinfo -u's output not a "CUSTOMER+Domain User" or something similar. I'm not sure anymore what I did to the PAM configuration, but here is what I currently have: root@lx:/etc/pam.d# cat samba @include common-auth @include common-account @include common-session-noninteractive root@lx:/etc/pam.d# grep -ve '^#' common-auth auth [success=3 default=ignore] pam_krb5.so minimum_uid=1000 auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass auth [success=1 default=ignore] pam_winbind.so krb5_auth krb5_ccache_type=FILE cached_login try_first_pass auth requisite pam_deny.so auth required pam_permit.so root@lx:/etc/pam.d# grep -ve '^#' common-account account [success=2 new_authtok_reqd=done default=ignore] pam_unix.so account [success=1 new_authtok_reqd=done default=ignore] pam_winbind.so account requisite pam_deny.so account required pam_permit.so account required pam_krb5.so minimum_uid=1000 root@lx:/etc/pam.d# grep -ve '^#' common-session-noninteractive session [default=1] pam_permit.so session requisite pam_deny.so session required pam_permit.so session optional pam_krb5.so minimum_uid=1000 session required pam_unix.so session optional pam_winbind.so At some point I joined the linux box into the AD domain. After (manually) creating a home directory on the linux box I can log in using the Adminstrator user with the password taken from AD. Now I run samba with the following setup: [global] netbios name = LX realm = CUSTOMER.LOCAL workgroup = CUSTOMER security = ADS encrypt passwords = yes password server = 192.168.20.244 #IP des Domain Controllers os level = 0 socket options = TCP_NODELAY SO_RCVBUF=16384 SO_SNDBUF=16384 idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = Yes winbind enum groups = Yes preferred master = no winbind separator = + dns proxy = no wins proxy = no # client NTLMv2 auth = Yes log level = 2 logfile = /var/log/samba/log.smbd.%U template homedir = /home/%U template shell = /bin/bash [export] path = /mnt/sdc1/export read only = No public = Yes Currently I don't care whether export is exported to everyone or just one user, I want to see somebody WRITING to that directory before I start fiddling with the authentication settings. (Who may access it). As mentioned, accessing the share from smbclient results in this NT_STATUS_MEDIA_WRITE_PROTECTED . Accessing it from windows shows ACLs that look correct (The user may write) - but it does not work, I can only read files not write. The directory to be exported looks like this: root@lx:/etc/pam.d# ls -ld /mnt/ drwxr-xr-x 5 root root 4096 2010-11-28 01:29 /mnt/ root@lx:/etc/pam.d# ls -ld /mnt/sdc1/ drwxr-xr-x 4 froh froh 4096 2010-11-28 01:32 /mnt/sdc1/ root@lx:/etc/pam.d# ls -ld /mnt/sdc1/export/ drwxrwxrwx+ 5 administrator domänen-admins 4096 2010-12-03 19:04 /mnt/sdc1/export/ root@lx:/etc/pam.d# getfacl /mnt/ getfacl: Entferne führende '/' von absoluten Pfadnamen # file: mnt/ # owner: root # group: root user::rwx group::r-x other::r-x root@lx:/etc/pam.d# getfacl /mnt/sdc1/ getfacl: Entferne führende '/' von absoluten Pfadnamen # file: mnt/sdc1/ # owner: froh # group: froh user::rwx group::r-x other::r-x root@lx:/etc/pam.d# getfacl /mnt/sdc1/export/ getfacl: Entferne führende '/' von absoluten Pfadnamen # file: mnt/sdc1/export/ # owner: administrator # group: domänen-admins user::rwx group::rwx group:domänen-admins:rwx mask::rwx other::rwx default:user::rwx default:group::rwx default:group:domänen-admins:rwx default:mask::rwx default:other::rwx My, oh my what am I overlooking?

  • Making Active Directory changes atomic

    - by Matt Simmons
    I've got a Windows 2003 Active Directory infrastructure, and there are times (such as when terminating an employee) that I want instantaneous propagation across both of my AD servers. Currently, I make the change in both places, which I suspect is unhealthy, but it's the only way I know to make sure that the account is disabled to every machine. Is there a better way? Do I have to wait for the normal propagation time for convergence, or is there a way to "force" it?

  • Is sending email from EC2 / Rackspace Cloud a bad idea?

    - by Michael Buckbee
    In this article it mentions that TrendMicro is now treating all emails from Amazon's EC2 as coming from "Dial Up Users": likely to be spam and this is creating severe deliverability issues with their emails. We're having all kinds of issues sending email from our app servers on Rackspace cloud (which may or may not be DUL'd) and I wonder if this isn't just a losing battle and we should try to get a different host for our SMTP server.

  • CNAME to another domain fails on some office networks, why?

    - by crashalpha
    Our domain "aspenfasteners.com" is hosted by Volusion. We have CNAME records "find" and "search" which point to site indexing accounts on www.picosearch.com. These addresses fail on SOME private office networks which have their own DNS. We suspect the problem comes from Volusion's own name servers, n2.volusion.com and n3.volusion.com. Volusion support on problems this technical is non-existant. We have tried an NSLOOKUP on find.aspenfasteners.com with level 2 debugging info, and we got the results below. Is it possible that the local DNS is recursing to Volusion's name servers, and that while Volusion DOES return the canonical name, they do NOT resolve the address? Can anybody with expertise in this sort of stuff PLEASE look at the NSLOOKUP below and tell me if we are right, because Volusion is giving me absolutely NO support on this topic. I need proof of where the problem lies. Thanks VERY much!

  • What happens when the server that the Remote Desktop Connection Broker goes down?

    - by Frank Owen
    I would like to setup the Remote Desktop Connection Broker to allow better load balancing of the two terminal servers we have as well as allowing the user to re-establish to the correct server if they get disconnected. My worry is, if I set this up and the server this service is running goes down, does the terminal server stop accepting connections or will they just lose the benefit of having RDCB turned on? I don't want to add another point of failure in this equation unless I have to.

  • Should I switch to Linux for development?

    - by Alex
    Is there any advantage to use a Linux machine to develop instead of Windows? Everyone at work tells me to switch to Linux, since I'm developing hard-core on linux anyway. I manage 40 servers, and do everything from DB to data-backend to developing web services. I don't find anything wrong with Putty. I"m just too lazy to install another OS... What do you guys think?

  • DNS Problems with .me domain

    - by tchaymore
    I recently registered a .me domain through GoDaddy. I set the nameservers to my slicehost servers immediately, and that change has been reflected in the .me WHOIS since day one. However, after almost two weeks, still can't look up the site. Is there something specific to .me domains or slicehost that I'm missing?

  • Other then DDNS, can a fake primary DNS server break anything else?

    - by Nimmy Lebby
    I am aware that the primary server listed in SOA record has to be valid for DDNS to work. Is anyone aware of any other application that uses the SOA listed primary DNS server in one way or the other? By a fake primary server I mean either: Inaccessible by anything else other than secondary servers (this is called hidden primary correct? unsure). A completely fake domain name like dig +short soa spamhaus.org

  • Identify OpenVZ virtual machine from inside

    - by Alfred Godoy
    Is there any way for me to identify which OpenVZ container I am in, from inside the container? I am working on a setup where OpenVZ machines shall boot the same (read-only) disk image, so I can not configure them individually in the file system. I need a unique identification for each of the virtual servers, to be used by scripts running inside the OpenVZ containers. (I'm running Debian Lenny, BTW.)

  • What alternatives are available for shared folders encryption in Windows 2003 Server?

    - by snakepitar
    People in our company asked to encrypting some of the shared folders published in a local Windows 2003 File Server. The requirements are: Encrypt the files, so only a user or group or users can open them Avoid password protected files. The encryption process should be transparent to the users Though files are encrypted, the backup software (BackupExec) must be able to copy and access binary for verification Cannot install tools/software in user's PCs, they want this to work automatically As we have very little experience managing servers, we'll be grateful for any help or suggestion offered.

  • Weird IIS with Windows Authentication + IE problem

    - by Paulius Maruška
    I have a website running on IIS and using Windows Authentication. All users that are configured to get access to the site are form a AD domain (not local users). In the properties of a Website, I have set to use the AD domain as the realm. Now, when using Firefox, Safari or Chrome - Everything is fine. When the user tries to open the site, he get's the login box. he enters simply "username" and "password" (let's pretend that it's an actual login and password :P) and he get's into the site. When using IE, however, things get nasty. When the user tries to open the site - he get's the login box. User enters the "username" and "password" again, but those get rejected! And when the second time login box pops up - it has the username filled in as "web-server-domain-name\username" which is wrong, because web-server-domain-name is not the domain where all users reside (it's "ad-domain"). I've spent days trying to figure out what's going on... Note, that if I manually enter "ad-domain\username" - I get accepted into the site without problems. So, my guess is that IE sends wrong username if domain is not specified. Anyway, IE is the only browser that triggers this behavior! Is it possible to do a server-side fix? Maybe it's possible to somehow auto-map the users to AD users? If it's not solvable server-side - is there a client-side fix for this? Thank you. PS: I'm more of a programmer than a sys-admin, so configuring servers isn't the strong side of mine... :P UPDATE: @Evan: Yes, "Digest authentication for Windows domain servers" is also enabled. @Eric: IIS version is 6.0. The authentication methods enabled are: Integrated and digest - all other methods are disabled. As for the security log. I looked at it, when doing "username" and "password" login in Chrome/Firefox and when doing "ad-domain\username" and "password" login from IE - the generated log messages are the same (I see no difference, anyway). When entering "username" and "password" I don't see any errors in the security (or any other) log, so can't tell what method it's trying to use. UPDATE 2: As suggested by Eric in the comments - I played around with Fiddler... While playing with it, I noticed, that when "username" and "password" is entered in FF and IE - the "Authorization" header value (encrypted) sent by IE is longer (almost two times) than one sent by FF. I tried to disable Windows Integrated authentication and only leave the Digest enabled - that fixed the problem (meaning, IE used the right realm just like other browsers), but that caused bazillion other problems with my site, because with Digest - user impersonation on the server doesn't work (that causes problems, when connecting to database etc). Any ideas?

  • Monitoring the status of accounts with IT Service providers (ISP, Domain Registrar etc.)

    - by Sholom
    Hi All, Short version: You have software that tells you when your servers power-outlet is down. It monitors multiple servers from one management console, alerts you when something is wrong etc. Does anyone know of software that will let me take the same approach to monitor if the money-outlet (the bill!) is down (not paid) to my IT Services providers (ISP, Domain Registrar, MX Backup service etc). I need a top down, centrally managed service that is capable of sending out alerts. Just like the one that monitors my own exchange server etc. I don't mind if i have to manually enter every payment. Long version: Our very likable but absent minded bookkeeper keeps neglecting to pay our IT vendors on time. Just this past week our internet service was disconnected. Same could happen to many other mission critical accounts (domain registrar, backup MX, anti-virus license, HackerSafe (McAfee secure) service and even an 800 number to name a few). As the sysadmin, i monitor my severs to make sure they are plugged into the power-outlet. I believe i should also monitor my services to make sure they are plugged in to their money-outlet. To compound the problem, when the power goes out someone else will likely notice and notify me. But if a bill is not payed, no one will ever notice until service is lost. Lost as in losing our domain name which would cause a lot more damage then the power failing on our server. [Solution] = [Doesn't work because]: Retrain the bookkeeper = Wishful thinking. Notify my manager = Already have (via email). Protects me, does not solve problem. Fire bookkeeper = What makes you so sure the next one will never forget? Bottom line: Humans are humans and sooner or later something critical will be royally messed up. We need to partner with a machine to help us out here. Anybody have the same problem? What software/solution do you use? I would like software that emails me when a bill is passed due just like i get an email when the power outlet fails. Anyone hear of anything like that? Thanks

  • Multi-core processors: Better performance running multiple applications?

    - by aip.cd.aish
    I realize for single applications - the application itself has to be designed to take advantage of multiple cores. But what about executing many different applications simultaneously? On my development machine at an average instance, I run multiple servers (a database server, a web server), multiple instance of IDEs (either Visual Studio or NetBeans), Web-browser with multiple tabs (in Chrome, each tab is a process on its own), FTP client, SSH client etc. Does having a multi-core system improve the ability to run multiple applications simultaneously?

  • RDP session re-locks right after login

    - by Jon Bailey
    For some reason, after users do the initial authentication, the system logs in (or unlocks) and locks the screen again within a few seconds (without dropping the RDP session). I've seen this on XP SP3 and Server 2k3. Clients are both major versions of the MS client, and rdesktop. Update: We've seen the issue on a range of machines from 2k3 server (no logon/post logon scripts on servers) to XP SP3. Multiple machines have the same issue - even coming from a fresh and fully patched install.

  • Automatically restarting Perfmon Data Collector Sets

    - by Scott Herbert
    I have a number of User Defined Data Collector Sets running on a Windows 2008R2 server, collecting perfmon stats from various servers. Whenever there is a network interruption, or a server rebooted (at worst, when the server which is running all these DCSs is rebooted), I have to manually restart some or all of the Data Collector Sets. Is there a way to configure them to automatically restart, or otherwise be more resilient?
