I am trying to configure SNMP server using xinetd on red hat. I am using non-standard port for it. My connection to server fails. I see the following log messages in /var/log:
Jan 26 17:23:31 [userid] xinetd[15023]: START: my-snmp pid=15047 from=192.128.11.21 Jan 26 17:23:31 [userid] xinetd[15023]: EXIT: my-snmp status=1 pid=15047 duration=0(sec) Jan 26 17:23:32 [userid] xinetd[15023]: START: my-snmp pid=15050 from=192.128.11.21 Jan 26 17:23:32 [userid] xinetd[15023]: EXIT: my-snmp status=1 pid=15050 duration=0(sec)
can anybody help to point out what is wrong in my config?
I'm trying to understand dns and I think the following commands should give me an "OK" or something... what am I missing?
Code: # dig @a.root-servers.net . ns >| db.root # named-checkzone . db.root zone ./IN: NS 'K.ROOT-SERVERS.NET' has no address records (A or AAAA) zone ./IN: NS 'L.ROOT-SERVERS.NET' has no address records (A or AAAA) zone ./IN: NS 'M.ROOT-SERVERS.NET' has no address records (A or AAAA) zone ./IN: has 0 SOA records
This is my first post. After executing /usr/bin/mysqladmin -u root password 'thepass' as a root, I get this:
Code: /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' SELinux is off.

How do I connect to the MySQL server using phpmyadmin?It's asking me for a username and password and I was not asked for a root password when I installed MySQL (unlike in Windows).I tried no password, I tried root as a password, I tried$ mysqladmin -u root -p blahEnter password: mysqladmin: connect to server at 'localhost' failederror: 'Access denied for user 'root'@'localhost' (using password: YES)'Nothing I've tried is working obviously.Why does this have to be so stupid? Why couldn't MySQL ask me what password I want to use?
Is it possible to configure the RHEL 5.5 syslog to accept SNMP traps? That is I want to use a central logging server to pick up other systems syslogs, and SNMP messages from systems that cannot use remote syslog functions.
Is the term a 'simple SMTP relay' a contradiction in terms?!I have an elderly Dell server on which I have just made a fresh install of 10.04 LTS server. I had 8.04 running on it for a long time, but I haven't tried an SMTP server before. It is a headless server with CLI (no GUI) and the latest version of Webmin installed.I have a basic LAMP server installed for a few websites using PHPbb and Joomla, and also I run a Mediatomb server for our household. When I installed I also chose to install mail services, but these remain masked behind NAT at the moment
I now want to set up an SMTP relay server so when I am working away and using different wifi points or my notoriously unreliable 3G dongle I can always send emails through the home server (from my iPhone and my laptop) rather than having to look up the SMTP server for each ISP of the place where I am working.
What I want is an authenticated server which takes my email and redirects it to my home ISP's SMTP server. I need only 3 authenticated users to have access (myself, my wife and my son). I don't need (or want) any incoming mail services at all.
Useful modules installed are: Dovecot, Postfix, Procmail mail filter, PAM - but how do I set them up?
Is there any simple setup that I could do, preferably through Webmin, but I can handle CLI if necessary?
I have looked at the Ubuntu help pages, but it looks so complicated to set up something that seems like it should be so simple to me.
our 9.x servers are running perfect. Just setup 5 new webservers, running 10.04LTS. Have SNMPD running, installed and the same config for all the servers I just copied over, by config, I mean one line, that's it. So the servers have the following /etc/snmp/snmpd.conf file rocommunity public
That's it. Now the only difference is looking at the ps on the local box's, a working one shows;
snmp 1096 0.0 0.0 50480 3756 ? S Jul02 9:21 /usr/sbin/snmpd -Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid where this one shows snmp 4962 0.3 0.0 48540 5884 ?

It almost seems something firewall is blocking, apparmor is not running, is there something else out of the box 10.04 has that I am just completly brain farting on?
I have a asterisk server running on my ubuntu 10.10 server box. I also have a zabbix server monitoring my networks. Asterisk have the possibility to show very interesting statistic with SNMP. But I cannot managed to set it up. This is the result i get when I try to get the version information with snmpwalk:
i am justin i'm 17 years old and new with linux, i use ubuntu and linux mint 7 and a friends of my has a dedicated fedora server. he asked me to intall a desktop manager ( or something that is the same, dont know how to call it ) so he could use remote desktop to acces his server
i have connected the server trought ssh and i am in the terminal. Now i want to install kde or gnome so i and my friend could use the server as a mail en WWW bla bla bla server. and my question is how i need to do that i tryd : yum groupinstall "KDE (K Desktop Environment)" and yum groupinstall "X Window System" but none works i have seen those commands on this forum so i tryd it.
Are there programs for this? Really really simple page layouts that you can edit and host from a graphical desktop that has your web browsers and Pidgen and VLC media player and everything running on it at the same time?
Old Commodore Vic 20/DOS/Wintel guy here who wants to make a first foray ever into Linux by building a home server with 10.04. I've found so much seemingly conflicting information that I'm lost at sea about hard drives.
I bought the Official Ubuntu Server Book, The (2nd Edition), and started reading it, learning about file system and planning a different /home partition, potential software raid, and such pre-install considerations.
The cheap hardware I had considered is: HP ProLiant ML110 G6 Intel X3440 2.53GHz 2GB Memory w/ DVD ROM & 250GB HDD 3 x SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM 32MB Cache SATA 3.0Gb/s 3.5" 6 more GB RAM for total of 8 The Samsung drives are Advanced Format. I read some reviews about OS partition alignment issues, and the past 2 days I've been down numerous rabbit holes of search on this forum and google in general about whether this will be a problem in 10.04. I'm wallowing in my own search-overload-induced fear, uncertainty, doubt, and paranoia now.
The release notes lead me to believe that "no brainer" support for these drives is now baked in to 10.04 ? That if I just follow prompts, the new install will partition and format drives properly aligned?
I've been running denyhosts on Ubuntu 8.04 servers without any problems using the how-to found hereow that I have a new Ubuntu 10.04 server running, I thought I would just install denyhosts from the Ubuntu repository not realizing that the paths and filenames of the install are different from the how-to I am used to using.I figured out what the name of the new denyhosts config file is (at least new to me) and the new location, but I'm not sure about the "allowed-hosts" config file.Does anybody know where the new path for this file is and whether the filename is still the same?
I have used for a long time Filezilla FTP Server on a windows server, for multiple users in my company around the country.Lately the windows box died and I said let's try ubuntu server 9.10. I configured to my best as a Samba file server and from a speed point of view it works even faster than the Winbox.Now getting to FTP setup, I had the following problem when setting vsftpd.How can I enable more directories for the user, each with its own rights. By example, in Filezilla I had two folders for each user: one was a specific folder in which he could also write, and the other was read-only. They were setup with aliases, so that when user login, he sees one continous list of folders.I tried with symlink, but couldn't do it. Also I searched through the man page but also did not find something specific for this task I would appreciate any help you guys could give me in order to solve this issue, using the best practice for vsftpd. Also note that I am open to other FTP servers as well.
Starting with Ubuntu Server 9.04, when I log in at times the OS smartly reports the number of updates available. I have a couple of questions of how to extend this functionality:
1) How could I back-port that functionality to 8.04 servers? Does that happen somewhere in the /etc/cron.daily/apt script? (Just the checking on # of packages needing updates, does not need to appear on the login screen.)
2) Then with that information, if the number >0 then use mailx to send admins an email. Since 9.04 and higher already do the first item, then in my mind #2 is the only thing needed for 9.04 and higher servers, and #1 is also needed for 8.04 boxes.
I've recently migrated my office PCs to ubuntu. My server doesn't server any big purpose but to provide Internet Connection to the rest of the nodes. Things were quite easier during the windows era using ICS.
Even in Ubuntu we were able to do it using the "shared network" option, simple & straight forward. But things got complicated only after installing "squid". Needless to say it brought in a lot of add ons as far as the http proxy serving is concerned & we are enjoying a better internet(http only) connectivity without any doubt. But we are not able to use our email clients, MS Outlook or Thunderbird
But to best of my knowledge squid strictly is a http proxy hence doesn't support handling requests on ports other than 80. (465 & 995 in my case)
Now I have two queries, 1. Can "Squid" really be used to do what I want here??? using iptables, port forwarding or any other mean & 2. Can any one suggest a good pop3/imap proxy as good as squid is.
I am planning to deploy an OpenLDAP server in my LAN for basic authentication, but I have no idea how to do it. I would like to know how to configure an OpenLDAP Server, and I would also like to know about knowledge resources, if any.
I want to configure squid server with SSL so that users send clear text username/password and also data in encrypted mode. i googled but all of the configuration is for reverse proxy not requests from users to proxy server in LAN for example.
I have a small problem with lmsensors and snmp since I upgraded my small server from 9.10 to 10.04. I use cacti to monitor my servers usage, disk space as well as temps and fans. This was running very fine before the upgrade, but now I don't get data anymore from lmsensors. It seems that SNMP doesn't give this information as before. (Cacti log says: "No sensor data was returned from SNMP")
sensors give the following output:
Code:
w83627dhg-isa-0290 Adapter: ISA adapter Vcore: +1.12 V (min = +0.00 V, max = +1.74 V) AVCC: +3.41 V (min = +2.98 V, max = +3.63 V)
I am a newbie to linux and running ubuntu server 10.10 (no gui), I had it configured with a fixed ip address and all was fine till I changed internet poroviders and got issued with a new router.
I am trying to configure the server to reflect the new settings of the new service provider. here are the contents of /etc/network/interfaces
Just so I got this right can someone tell me if I am right here. address is the IP I wish to give to my server statically. and gateway is the ip of the router. When I try to ping the router I get
Code: Ping 192.168.15.1 (192.168.15.1) 56(84) bytes of data. From 192.168.15.1 icmp_seq=1 Destrination Host unreachable When I try to ping the internet i get :
[Code]...
Is there anyone that can shed some light on where my problem may be. As i said before I got the new router I had been working with the server no problem.
How to configure DNS server for my small network. In Fedora Linux operating system I want to use Linux as a DNS server for my small office. there are files " /etc/hosts" and "/etc/resolv.conf ".
what is the purpose of these files and in which situation we use these files? For configuring a new DNS server. how can i configure my own DNS server for my small office? Any blog or site in which they show steps to configure DNS server.
I've tried to configure DRBL server to use Clonezilla and that is required me to setup DHCP, TFTP servers.But I've gotten a lot of errors from them - so please look at my attachments from /var/log/messages and dhcpd.conf - help me to find out what are wrong with them.
I am trying to install and configure LTSP on a server for a HP thin client to boot off. The version of Ubuntu that I am using is 11.04 x86 and it is a fresh install on a dual core system with 2GB RAM. I followed a guide which comprised of these commands.
sudo apt-get install ltsp-server-standalone openssh-server sudo ltsp-build-client or if your on a 64-bit system with 32-bit machines do sudo ltsp-build-client arch i386 for editing the servers IP values use /etc/ltsp/dhcpd.conf after that you need to restart DHCP server sudo /etc/init.d/dhcp3-server restart and update sshkeys -sudo ltsp-update-sshkeys and if you updated dhcpd.conf then you need to update you image also by typing in terminal ltsp-update-image
Everything seemed to install as it should but when I try to boot from the thin client it just times out and says no DHCP or proxy invites received. I turned DHCP off on the router and even tried another router, but I still get nothing. I am at a bit of a loose end and I hope someone on here can point me in the right direction of where I am going wrong.
