I just have a caching nameserver on my Fedora PC:
I configured my DNS server addresses in the Network-Manager Applet: 127.0.0.1, 8.8.8.8
Even with Wireshark, I can see it:
So the big question: Why don't the host command or my web browser recognize that I have modified audit.median.hus IP address?
I have set up SSH and redirected the ssh server to listen on another port other than 22 for a bit of added security.
Now in hosts.deny I have:
ALL : ALL
In hosts.allow I have:
SSH : ip_address_of_client
I can no longer connect. I get the message: ssh_exchange_identification: Connection closed by remote host.
When I change hosts.allow to read:
ALL : ip_address_of_client
I can successfully connect the server.
However, I only want to allow SSH access in hosts.allow. What is the correct syntax?
I have tried and failed with each one of these:
SSH : ip_address:port_number
SSH2 : ipaddress
sshfwd-portnumber : ip_address_of_client
I'm not sure if this is best done in Perl or Bash. I'm thinking surely someone else has created something close to what I'm looking for. The results of the script would be that someone would kick off "linux_hosts.sh" r whatever you want to call it, then a top "folder" of options (with hosts contained within each of these top menu choices), then, based on which number corresponds to that top level, they're presented with a set of linux hosts that are relevant to that top level name. Example:
$ linux_hosts.sh
1. VMware hosts 4. Private Domain
2. ESX servers 5. Red Hat boxes

I have a VPS from Providerservice and I am their customer for over a year now. They've been great throughout the year. They had awesome support and awesome Network quality. I Host GameServers and since the last month, my Servers have been giving big lag jerks to all the clients connected. Like one big lag jerk every 5 minutes. When such a thing happens, the first thing I usually check is the Network. From 10 different machines, I did MTR traceroutes and there was not even a single packet that was lost so I was sure that the Network is not causing it. I observed my CPU usage, RAM usage, HDD usage and everything was normal but GameServers still lagged. Now today, I reloaded a complete new Debian OS and copied the Game Server files exactly from my other machines.
There was no extra program or software installed on the server, but that didn't help remove the Lag. So now I'm sure its not my VPS that causes it. Such a thing happened with me before. No Network packets were being lost and my VPS showed CPU/Ram/HDD to be normal. I asked my Provider and they said one of our user is spiking the CPU with a large number of SQL queries and that's why your lagging. But I talked to this company, they've checked their Host machine and they see nothing wrong with it. According to them, everything is normal at the Host machine. So we are short of ideas on what to do and that's why I'm here to take some expert opinions, the following things are for sure :
-> My Game Server files are exactly as I run on other machines without Lag and even on the current machine 1 month ago without Lag.
-> The VPS itself is not causing the Lag.
-> I've checked Network and no packets are loss, not sure about any difference between ICMP or UDP packets since the game is UDP.
The most probable thing is the Host machine itself. This usually happens when the Game Server falls out of resources and gets stuck.
I have installed bind9 for DNS. I have also installed Apache2, PHP5, MySQL, and correctly configured these together. When I view domain1.co.uk it currently works fine as required. I would like to change it to:
* /var/www/domain1.co.uk/prod/ - becomes the root dir of domain1.co.uk
* /var/www/domain2.co.uk/prod/ - becomes the root dir of domain2.co.uk
Nevertheless, I have created a the following files; these are copies of the "default" file and correctly amended. the required destination directories are in place!
* /etc/apache2/sites-available/domain1.co.uk
* /etc/apache2/sites-available/domain2.co.uk
I then executed:
Code:
sudo ln -s domain1.co.uk ../sites-enabled/domain1.co.uk
Code:
sudo ln -s domain2.co.uk ../sites-enabled/domain2.co.uk
It is important to understand domain1.co.uk and domain2.co.uk represent 2 Existing domain names I own, and both point to my server.
domain1.co.uk currently works in /var/www
Why I would like multiple domain names on the server.
apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.

View 1 Replies View RelatedI have been trying to build the HP Qlogic Netxen, nx_nic, driver on Ferdora13 kernel 2.6.33 but facing with "missing kernel-devel package" errors. As per the instructions in the driver spec, when i try to do rpm build, i get this error. I tried the rpm build installing kernel-devel-i686 pkg but it only shoots back with
error: Failed build dependencies:
kernel-devel-i586 = package is needed by hp-nx_nic-4.0.544-2.src
But when I installed kernel-devel-i586 pkg for kernel 2.6.30 the rpm build continued beyond this error point only to give some other RPM build error atleast to say there was no missing kernel-devel pkg error. Has anybody come across any such error with any other driver? or nx_nic in specific? Does this error mean kernel-devel-i586 a MUST for this driver? As far as I know there is no -i586 pkg for kernel 2.6.33 when i searched in kernel-devel repository! I am not sure, if this forum is right place for posting this question. If not, pls re-direct me to the right one.
In our environment we are using EMC for storage. We are using Qlogic provided drivers and PowerPath and the OS is RHEL5.3. Currently we have 2 Luns connected in one of our server (emcpowera & emcpowerb) and storage team has allocated another 100Gb Lun to that system, my doubt is if I execute "ql-dynamic-tgt-lun-disc.sh" script that would be enough to detect the Lun and see the device under /dev/ as emcpowerc or I need to execute "powermt config" and "powermt save" commands also.

View 6 Replies View RelatedWe had a problem with the NIC 10Gig Qlogic NICs and had to swap them with Emulex 10Gig NIC cards. The swap has been done. There are several severs (about 100)for which we need to check if the hands-on still left the q logic card in them. So, I wrote a script using dmesg and grepped for "qlogic" or " NC522SFp" and my script checked for all the servers and returned no presence of "qlogic". But few of them have q logic still in them. So, is there any other way through which we can exactly tell whether q logic card is still present or not? I used:
dmesg | grep -i "qlogic" or
dmesg | grep -i " NC522SFp"
and found nothing in the o/p. But when I checked using ifconfig -a, then I see the q logic mac ids for eth4 & eth5, which means the Q logic is still present.But not sure whether ifconfig is the real way to find out the presence of these cards.
My system is an Altix3000 running: (Linux sgialtix 2.4.21-sgi304r1 #1 SMP Sat Jan 29 22:43:29 PST 2005 ia64 ia64 ia64 GNU/Linux) (redhat-release=redhat-release-3AS-8.3).

View 1 Replies View RelatedI am trying to setup a blade server that has a QLOGIC 4062 mezzanine card to handle the iscsi traffic coming from an HP MSA 2312i SAN. I cannot seem to figure out how to get the HBA to talk to the SAN. Just to ensure the SAN was setup OK, I used the onboard netextreme NIC w/iSCSI to connect to the SAN with iscsiadm. This all works no problem. BUT, I bought the mezzanine cards to take this load of my NICs.
I know that the OS sees the two ports on the mezzanine card as dmesg shows them. This is my first time configuring a separate HBA on a blade system, so I'm kinda lost what to do with them. I have entries in the modprobe.conf file for eth2 and eth3 aliased to qla4xxx. What I am not sure about is the config for each eth2/3 device. If I ifconfig my device to the specific ip and subnet/netmask my SAN is on, I can get any response from the SAN.
Also I would have expected iscsiadm -m iface to pick up on the qlogic devices, but they don't show up in the ifaces directory. I tried to manually create an iface file for each, and it seems to be ok with that, but when I try to discover targets, I get communication errors. (I am compiling a file with all the outputs from various commands and errors, and will put them here once I have them).
What I don't understand is the process of setting up an HBA. I am quite able to setup iscsi over the regular NICs, been doing that for a while, but these HBAs have me stumped.
I also installed the qlogic qla4xxx driver and SANSurfer, but SANsurfer didn't see the HBAs. I think this was due to the age of the sansurfer software...other people have reported this as well.

We have a SuSE/SLES 9 server that boots from a fibre channel card, using volumes from a NetApp filer.
We previously had the server booting from the LUNs on the filer, but after some tinkering around with the fibre channel BIOS, we have the situation where the LUNS seem to be mounted, the OS boots, starts to initialise everything but then stalls, saying:

I'm trying to find out when QME2572 (Qlogic) card became support by the kernel. We have a RHEL 5.1 system that is moving to new hardware, however the kernel at this release doesn't support the new hardware, due to the Qlogic card change. I tired the Redhat KB and Bugzilla. Is there a Kernel change list etc I can search. Never really played around with the kernel too much so I'm just after some pointers for looking up this information. Offically its not supported until Redhat 5.3, I'm trying trying to research kernel info so I can tell the customer they have to upgrade.

I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.
I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)
