Networking :: Cannot Start NSCD - PID Does Not Exist
Mar 1, 2010
Not sure this is correct place, but I think it's related to network. I'm using CentOS 5. I installed nscd successfully using yum. But I can't start nscd. It shows [ OK ], but stop right away, and I can't found any nscd process.
/var/log/nscd.log is empty, /var/run/nscd/nscd.pid has a PID that doesn't exist, and here's /etc/nscd.conf
Code:
#
# /etc/nscd.conf
#
# An example Name Service Cache config file. This file is needed by nscd.
#
# Legal entries are:
#
#logfile<file>
#debug-level<level>
#threads<initial #threads to use>
#max-threads<maximum #threads to use>
#server-user <user to run server as instead of root>
#server-user is ignored if nscd is started with -S parameters
#stat-user <user who is allowed to request statistics> .....

I'm a network services rookie and I am seeing this error, but it doesn't seem to be effecting functionality. Nov 22 12:12:16 r01 nscd: nss_ldap: reconnected to LDAP server ldap://10.5.1.4 after 1 attempt This error is scattered through out my logs. We are authenticating this Red Hat server to another OpenLdap server. Everything seems to work just fine and we are not even using Kerberos as this is a render server. We set-up ldap right in the GUI, nothing fancy.
RHEL 5.4, Basic install, again, nothing fancy. LDAP does seem to be working fine and allows the right people to login to the machine. We have two of these machines running and both are configured exactly the same and getting the same errors.

This is are magic file who kill 20 linux nodes today and.. of course i want to ask - What i can do for limiting size of nscd.log file? i try to find help in man files: nscd and nscd.conf - but nothing about log size. (just paranoia mode with auto restarting.. but this sounds ugly. i need just limit log file size)

I am a non-root user on my Lab computer with RHEL4 OS and am trying to install Glibc-2.11.1 on it .. for proper installation I used a directory other than the source directory of Glibc and ran configure which was fine, then I ran make which also ran fine.. but when I ran "make install" an error came up which was :
make subdir=nscd -C nscd ..=../ subdir_install
make[2]: Entering directory `/data/sandy/Desktop/Gotten/glibc-2.11.1/nscd'
gcc -pie -Wl,-O1 -nostdlib -nostartfiles -o /data/sandy/Desktop/Gotten/glibc-build/nscd/nscd -Wl,-dynamic-linker=/data/sandy/program2/glibc/lib/ld-
[Code].....
so I guess I don't need to specify the configparms .. but anyway I did it as earlier I wasn't sure what would solve my problem with NSCD.. Then I moved to make and all went fine, but the same error popped up during "make install"
install the Glibc package being a non-root user?

we're running an Ubuntu 10.04 LTS network on our company, authenticating against an Openldap/heimdal-kerberos server.Previously, the clients were authenticating against a Windows 2003 Domain without any problems.After modifying the krb.conf, ldap.conf, nsswitch.conf and nscd.conf files to authenticate the machines against the openldap/heimdal setup, we started experiencing strange problems.
One issue is, for example, the polkit-agent-gnome not starting. This component integrates policykit into gnome. It looks like the agent is unable to start due to some kind of delay with DBUS. Starting the agent manually keeps giving errors until about 70 seconds after login, when the agent can be started without problems. During the delay it is also impossible, for instance, to open the "shut down" menu on the top right of gnome. You can click on the menu, but nothing appears.Trying to start the polkit-agent manually gives these errors (I'll be attaching detailed errors when at work!):
Code:
DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken
GLIB ERROR ** default - Not enough memory to set up DBusConnection for use with GLib It really looks like DBus or something related to it is starting "too late" but I can't seem to find the reason. I'm pretty sure this has to do with some timings or whatever in the krb/ldap config files...

I was having a problem on my squid server whereby 1 website would timeout daily and return a nscd not found error: [url]....There may be other sites but this is the only one I know of. A selection of other sites still work correctly, which is the strange thing.I have found that by restarting the dns cache everything works again: /etc/init.d/nscd restart.I never know quite when this will timeout so it is not very good for people accessing that site on the server.

My company uses (as do many others) a common set of keys between the development machines. This has always seemed to work until recently... now the presence of any keys (server-side) causes the SSH server to crash, and the client immediately gets kicked. The interesting part is that the ONLY clients who crash the server are the ones with the common keys. If you are an unknown host, then you are prompted with a login, and you can get in. From the client you see this:
Code:
[root@localhost ~]# ssh localhost
Last login: Fri Apr 9 14:36:44 2010 from jjinno.foobar.local
Connection to localhost closed.
And from the server (the same box in this case) you see this:
Code:
Apr 9 14:37:59 cld10-2 kernel: sshd[19967]: segfault at 00000000000000f0 rip 00002b0bafc8d65b rsp 00007ffffd836c90 error 4

I'm getting millions of log entries in my nscd.log like the ones below. There's no connection to (or from) this IP address so I'm totally at a loss for what would cause this.

I've been fighting to get my wireless working and I've finally made some progress. I can actually manage to connect to my wireless network and so far it has been quite stable (fingers crossed).
However there is one slight nag. My wlan0 interface driver refuses to start at startup. When I type iwconfig its just not there. To fix this I have to manually run "rmmod rtl8187" and then "modprobe rtl8187". Then it works fine.
I've been trying to make a script to automate this but without success. I've tried both editing my rc.local and kde startup .xinitrc
How I could get those two commands to run automatically at startup after the boot process? I'm running Arch Linux and KDE 4.3

We purchased a virtual server from GoDaddy (1 month trial) to set up as a proxy for our networks (24 of them). I am having 2 separate issues. The first is I can't configure/install NAT and support is telling me the only way I can is to purchase a dedicated server. Here's the error:
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3128 iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Here's the fix: [URL] So, what I am hoping to do is configure this by just opening port 3128 directly, and only allowing access from our networks. As a test I did this and allowed only from our office and it did not work. However I can't connect, so I am wondering what I am doing wrong? Here's my squid configuration:

This is my first question, I am not a linux expert. I found an interesting thread about this but it is related to RH 9 (http://www.linuxquestions.org/questi...-src-rpm-78937) I'm wondering if this database exists for RH EL5 too and in case if someone can point me to the right path to get it and how to install it. the system where I'd need to apply it is 2.6.18-92.el5 x86_64 GNU/Linux. The system is not connected to Internet.

I just started setting up a linux box in the office...I have some experience with ssh commands but not setting up a linux system and stuff.The box is connected to our network but I have no clue how to make windows & osx talk with it. How can I go by doing that and also setting up an apache server to be able to connect through network. Right now I have apache/linux/mysql running it works when i go to localhost, but I would also like to let all the computers in office to access it. I would guess that will deal with virtual host which I know how to setup. I just need to setup an IP.

All my yum commands fail because it searches for pgdg90 : Error: Cannot retrieve repository metadata (repomd.xml) for repository: pgdg90. Please verify its path and try again. How can I stop it looking for a non existing location? If I use locate to find pgdg90 it returns /var/cache/yum/i386/12/pgdg90. If I ls /var/cache/yum/i386/12/ there is no pgdg90.

I installed Ubuntu 9 on my kids' computer a while back and usually the computer boots up and goes directly into Ubuntu. However, this morning when they booted it up, the following error message displayed: "The GDM user 'gdm' does not exist. Please correct GDM configuration and restart GDM." It seems that they had inadvertently messed up some configuration files. After pressing 'OK' it asked me for my user name and password, which I supplied, but that didn't work either. So, either I've forgotten my password or my kids seriously messed up their computer, so much so that I can even work with it in command line. I was thinking about simply reinstalling Ubuntu and possibly updating to version 10, but I'd rather not lose the files on the computer. Thus my question: Does anyone see a way of not losing my and my kids' files while getting back into Ubuntu?

I use Network Manager to create an Ad-Hoc setup, no security, dhcp, all the simple stuff. Theres just no button or anything to connect to it The internet guide i found said create the network and then use network manager to "connect to a hidden network". No success, not even the wifi attempting to connect when i manually type the SSID of my adhoc. Other than Ad-Hoc, wifi connections are super easy and fast, click any access point i find and type a password "tada!" Internet.this Ad-Hoc issue so i can finally kick the windows habit?Maybe this info will help:
atheros 9285 wifi adapter (ath9k driver)
Linux 2.6.35.9-64.fc14.i686
KDE 4.5.4

I have a Dell Inspiron 1464, I can not get the wireless to start. I can see my wireless router when I scan for wireless devices in knetwork manager. But there is a yellow shield next to it, so I'm guessing something is missing. I also see no network activity with tcpdump on another box on my home network
