  • Can't configure PAM + LDAP on Debian Lenny - Getting error=49 on server logs

    - by Jorge Suárez de Lis
    I've been migrating some servers and desktops using Ubuntu 10.04 from getting the users from an old OpenLDAP implementation to a newer Centos Active Directory. I haven't had any problems so far, until I reached a Debian Lenny server. I've set up the server as the others, setting /etc/ldap.conf and /etc/ldap/ldap.conf. However, when I issue "getent passwd", I get nothing from the LDAP server. Reading the pam_ldap manpage, I realized that /etc/ldap.conf was not an accepted file by pam_ldap -it worked with Ubuntu though-, so I renamed it to /etc/pam_ldap.conf. Same result. However, once I've changed the name of this file, when I login using SSH I get this on the LDAP server logs: [20/Jul/2012:11:19:40 +0200] conn=16501 fd=155 slot=155 connection from x.x.x.50 to 10.1.176.237 [20/Jul/2012:11:19:40 +0200] conn=16501 op=0 BIND dn="uid=ubuntu,ou=Applications,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:19:40 +0200] conn=16501 op=0 RESULT err=0 tag=97 nentries=0 etime=0 dn="uid=ubuntu,ou=applications,ou=citius,dc=inv,dc=usc,dc=es" [20/Jul/2012:11:19:40 +0200] conn=16501 op=1 SRCH base="ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" scope=2 filter="(uid=jorge.suarez)" attrs=ALL [20/Jul/2012:11:19:40 +0200] conn=16501 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U [20/Jul/2012:11:19:40 +0200] conn=16501 op=2 BIND dn="uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:19:40 +0200] conn=16501 op=2 RESULT err=49 tag=97 nentries=0 etime=0 The password isn't working. I don't know that could be wrong, anything else seems to be OK.

Maybe this is not supported by Debian Lenny? On pam_ldap.conf, I've set up this, as in all the other servers: # Do not hash the password at all; presume # the directory server will do it, if # necessary. This is the default. pam_password md5 Also tried clear, but it didn't work. Anyways, it's weird that issuing getent passwd still gets me no users. However, if I use pamtest from the package libpam-dotfile to test login, it works. # pamtest ssh jorge.suarez Trying to authenticate <jorge.suarez> for service <ssh>. Password: Authentication successful. # pamtest foo jorge.suarez Trying to authenticate <jorge.suarez> for service <foo>. Password: Authentication successful. But "su" won't work also: # su jorge.suarez Id. descoñecido: jorge.suarez Just the output from getent passwd : # getent passwd root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/bin/sh bin:x:2:2:bin:/bin:/bin/sh sys:x:3:3:sys:/dev:/bin/sh sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/bin/sh man:x:6:12:man:/var/cache/man:/bin/sh lp:x:7:7:lp:/var/spool/lpd:/bin/sh mail:x:8:8:mail:/var/mail:/bin/sh news:x:9:9:news:/var/spool/news:/bin/sh uucp:x:10:10:uucp:/var/spool/uucp:/bin/sh proxy:x:13:13:proxy:/bin:/bin/sh www-data:x:33:33:www-data:/var/www:/bin/sh backup:x:34:34:backup:/var/backups:/bin/sh list:x:38:38:Mailing List Manager:/var/list:/bin/sh irc:x:39:39:ircd:/var/run/ircd:/bin/sh gnats:x:41:41:Gnats Bug-Reporting System (admin):/var/lib/gnats:/bin/sh nobody:x:65534:65534:nobody:/nonexistent:/bin/sh libuuid:x:100:101::/var/lib/libuuid:/bin/sh Debian-exim:x:101:103::/var/spool/exim4:/bin/false statd:x:102:65534::/var/lib/nfs:/bin/false sshd:x:104:65534::/var/run/sshd:/usr/sbin/nologin luser:x:1000:1000:Usuario local de Burdeos,,,:/home/luser:/bin/bash messagebus:x:105:107::/var/run/dbus:/bin/false sge-admin:x:1001:1001:Administrador do SGE,,,:/home/cluster/sge-admin:/bin/bash ntp:x:107:110::/home/ntp:/bin/false haldaemon:x:108:111:Hardware abstraction layer,,,:/var/run/hald:/bin/false vde2-net:x:109:114::/var/run/vde2:/bin/false uml-net:x:110:115::/home/uml-net:/bin/false polkituser:x:111:116:PolicyKit,,,:/var/run/PolicyKit:/bin/false Debian-pxe:x:113:65534:Dummy user for Debian pxe package,,,:/home/Debian-pxe:/bin/false Nscd was stopped from the beginning.

  • How do you cache web pages with a personalized header using caching reverse proxy such as Squid, Var

    - by Continuation
    Pretty much every page of my website is dynamically generated. However they don't change that frequently (kinda similar to a forum page). So I'd like to cache them using a caching reverse proxy such as Squid, varnish or Nginx. The problem is that for my logged-in users, each of them will see a personalized header saying "Welcome John Doe. Logout" on the upper right corner of the page (just like serverfault). While users who aren't logged in will see a header that says "Login" instead. So basically even though every user will see the same page in general, they all slightly different version due to that personalized header. Is there any way so that I can cache the "main" part of the page and serve it from cache while generate the personalized header dynamically for each individual user? This must be a very common problem. How is it solved in general?

  • Strange DNS problem [seems to be IPv6 issue]

    - by Homer J. Simpson
    Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • CPU load, USB connection vs. NIC

    - by T.J. Crowder
    In general, and understanding the answer may vary by manufacturer and model (and driver, and...), in consumer-grade workstations with integrated NICs, does the NIC rely on the CPU for a lot of help (as is typically the case with a USB controller, for instance), or is it fairly intelligent and capable on its own (like, say, the typical Firewire controller)? Or is the question too general to answer? (If it matters, you can assume Linux.) Background: I'm looking at connecting a device (digital television capture) that will be delivering ~20-50 Mbit/sec of data to a somewhat under-powered workstation. I can get a USB 2 High-speed device, or a network-attached device, and am interested in avoiding impacting the CPU where possible. Obviously, if it's a 100Mbit NIC, that's roughly half its theoretical inbound bandwidth, whereas it's only roughly a tenth of the 480 Mbit/second the USB 2 "High Speed" interface. But if the latter requires a lot of CPU support and the former doesn't...

  • How to integrate Windows Server 2008 R2's NPS with Cisco switches?

    - by Massimo
    I need to evaluate in a lab environment the use of Windows Server 2008 R2's NPS for 802.1x authentication with Cisco Catalyst 3750 switches; the general idea is to only let clients connect to the company network if they can provide valid domain logon credentials, placing them in a restricted VLAN instead if they can't. NAP would also be a bonus, but it can be evaluated later; the main point now is only 802.1x authentication. Although I have very good knowledge of Windows and Active Directory (on the Microsoft side) and quite good knowledge of Catalyst switches (on the Cisco side), I'm totally new to 802.1x; I'd really like some general guidelines and help here, and some sort of implementation guide would also be very useful.

  • Puppet, Nagios, Munin on cPanel based hosts

    - by WinkyWolly
    I've been managing 20-30~ cPanel based hosts over the past year with Puppet, Nagios and Munin for general monitoring / trending however a lot of the methods I've had to use to deploy / manage things such as configurations a pain. For those of you who aren't familiar with cPanel - it adds a few things to yum exclude such as perl*, ruby* and so forth. This causes issues with me being able to bootstrap monitoring on a new server via Puppet (well via the Package type) due to a bunch of conflicts with installing via Yum. Now I could create a custom RPM for everything and remove certain dependencies from the spec file however I would like to avoid this if possible. Does anyone have any proposed functional ways to manage this sort of environment? Currently I install Puppet, Facter and Munin via RPM's and force install using --nodeps and such (since they're installed, just no the ones Yum wants). Nagios I installed manually from source at this time (likely will create RPM's however I want to tackle this general issue first).

  • Good set of web hosting permissions?

    - by Jorge Israel Peña
    Hey guys, I just got a linode and I'm in the process of configuring it. It's running nginx with php-fpm and passenger. nginx was compiled and is running as user nginx. php-fpm (php with fastcgi process manager) is running as www-data (in group www-data). My sites are currently in /var/www, so for example /var/www/test.com I'm just wondering what the general 'flow' of things is. So for example, /var/www is owned by root, should I chown of /var/www/test.com to nginx or www-data? Or should I put nginx in the www-data group? How should site uploading work, I just transfer files to the /var/www/test.com directory as root (sudo) and then chown -R www-data:www-data .? Thanks. I'm capable of figuring things out on my own, I'm just wondering what the typical/general way of handling users/groups/permissions/site-files is on linux with a webserver.

  • Why Standards Place Limits on Data Transfer Rates?

    - by Mehrdad
    This is a rather general question about hardware and standards in general: Why do they place limits on data transfer rates, and disallow manufacturers from exceeding those rates? (E.g. 100 Mbit/s for Wireless G, 150 Mbit/s for Wireless N, ...) Why not allow for some sort of handshake protocol, whereby the devices being connected agree upon the maximum throughput that they each support, and use that value instead? Why does there have to be a hard-coded limit, which would require a new standard for every single improvement to a data rate?

  • Would NetBSD be a good choice for a web server?

    - by Alexander
    I've the choice of crafting a NetBSD image for a Xen VPS host, and was just wanting to play around as I like BSD and wished to use it for my general web hosting. I will be hosting a low-mid traffic website and maybe a few other simple services. Do you think NetBSD would be a sufficient choice, in terms of general performance of multiple system users and fair amount of traffic to Apache compared to what Linux could normally handle? I am concerned if I do start to really like it and keep it, I may be limiting myself if I am to move further with my web host and get more traffic (and maybe a lot of FTP access and user shell accounts) Ken

  • Enabling Compiz Viewport Switcher key bindings

    - by David Moles
    I'm running compiz 0.8.2 with compizconfig on Scientific Linux 6.2 with Gnome 2.28.2. In the compizconfig "General Options" I have "Desktop Size" set as follows: Horizontal Virtual Size: 6 Vertical Virtual Size: 1 Number of Desktops: 1 This gets me the layout I want, i.e. 6 workspaces in a horizontal layout. Ctrl-alt-cursor-keys work fine for switching between them. However, I can't figure out how to get key bindings for specific workspaces. I've tried enabling "Viewport Switcher" in compizconfig, and tried various combinations both in "Number-based viewport switching" and "Go to specific viewport", to no apparent effect. My first thought was that something else was eating the specific key bindings I chose, but I think I've tried every combination of shift, control, alt and super (i.e., the Windows key) by now. I tried setting 6 desktops under "General Options" instead of one desktop with horizontal virtual size 6, but that doesn't seem to make a difference either. What am I missing?

  • How do I examine my Windows firewall outbound rules?

    - by David
    I need a program to listen to port 9000 on localhost with my Windows firewall. I've created an outgoing and an incoming rule for my program but I can only see my incomming rule in the Windows firewall general menu? I've also noticed that I've many more outgoing rules in my outgoing rule menu but I can only see 4 outgoing rules in my general firewall menu but I see many many more incomming rules? The program doesn't listen to port 9000 or it doesn't working. I've also tried netstat -a -p to no avail. I didn't see 0.0.0.0:9000 in the output? How can I check if my program listen to port 9000 or connect to port 9000 when it's open?

  • Windows terminating system processes

    - by jemper
    To be sure nobody will answer me with advice on not trying to terminate critical (system) processes - I'm relatively experienced in programming and Windows in general - I'd know what I'm doing so far. So there are these processes that can't be terminated with taskkill - system processes in general. But there also is, for example my Anti Virus program that makes itself "unterminateable". How can I access and mainly terminate system processes under windows? (kill.exe by Microsoft doesn't work) How do processes like anti-virus programs protect themselves? How can you turn them off again, then?

  • How do networking ports work? Can I configure the ports that client and server use?

    - by joedotnot
    Let's say i have a "server" program listening on address 1.2.3.4:69 (i.e. remote port 69) When i connect from a "client" program to it, typically i would specify the IP address + port of the target or server system; But what port would the client be using ? And how does the server know which port to connect back to the client on? I understand this question is very general, but just wanting to get a general feel for how things work. Then extending this to a specific protocol, say FTP (typical port 21), can I change it such that the server uses port 69, but the client uses port 100? And similarly, for Remote Desktop in WinXP (typical port 3389), i know how to change the server port to be something other than 3389, but how does one change what port the client uses (if at all possible)?

  • Mitigating the 'firesheep' attack at the network layer?

    - by pobk
    What are the sysadmin's thoughts on mitigating the 'firesheep' attack for servers they manage? Firesheep is a new firefox extension that allows anyone who installs it to sidejack session it can discover. It does it's discovery by sniffing packets on the network and looking for session cookies from known sites. It is relatively easy to write plugins for the extension to listen for cookies from additional sites. From a systems/network perspective, we've discussed the possibility of encrypting the whole site, but this introduces additional load on servers and screws with site-indexing, assets and general performance. One option we've investigated is to use our firewalls to do SSL Offload, but as I mentioned earlier, this would require all of the site to be encrypted. What's the general thoughts on protecting against this attack vector? I've asked a similar question on StackOverflow, however, it would be interesting to see what the systems engineers thought.

  • How do I install a language pack in Windows 7 Home Premium?

    - by ekaj
    Specifically, I want Korean (link), but I hope this helps other people in general. According to this page, it is only possible for Ultimate and Enterprise. Specifically, I'd like to enable my keyboard to type in Korean, and I specified Korean as the input language (Start - type "Input Languages", only result). Under the General tab, I selected Add, and specified Korean.. but it doesn't work, because the language pack isn't installed I presume. Would anyone know how to add different language input / packs to Windows 7 Home Premium? Also, I tried following this tutorial on adding a language pack to HP, but the .cab keeps disappearing so it will not work. Note: Unlike the link in the tutorial as well, I do not have an option to change the display language of Windows, only the option to change input methods.

  • AD Local Admins without password sharing

    - by Cocoabean
    My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

  • Why don't they clean up the Windows folder? [on hold]

    - by NeoLegends
    To me, that thing seems like an utter mess, at least most parts. Some are pretty organized (.NET and GAC-Folders), but most of the others (System32) are not. Wouldn't it improve the general developer productivity if they cleaned it all up? In general - I don't know why they didn't stop that folder becoming a huge mess, and why they don't take any efforts to reduce it. (Win 8 Settings App sits in System32 while Store sits in Root directory, iirc) FHS isn't perfect, but it's far better than that...
