# iptables -t tproxy -n -L iptables v1.3.5: can't initialize iptables table `tproxy': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Does exist a tproxy module for CentOS's kernel (2.6.18) ?

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:

On my diskless cluster, I want to open a port on the image that nodes use it.Here is what I get:
Code:

View 1 Replies View RelatedI need to set up an ip table and a transparent squid proxy as followed: I have 3 machine: Machine 1 works as a squid proxy. It has 2 interface eth1 and eth2.
eth1: 192.168.99.2 (Connect to eth1 of machine 2)
eth2: 192.168.98.2 (Connect to eth1 of machine 3)
machine 2 works as a webserver
eth1: 192.168.99.4
machine 3 works as a web client.
eth1: 192.168.98.4
my responsibility is to send all tcp traffic from machine 3 at port 80 to my squid proxy. In order to fulfill the tasks, I have edited the squid.conf as followed: Code: http_access allow localnet http_access allow localhost and in machine 1, I tried 2 ip tables command: Code: iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 80 -j DNAT --to 192.168.99.2:80 iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 80 I don't know if it is right or wrong.
To expand: I'm trying to set up a box with l7-filter, and I need to patch and compile iptables 1.4.1.1 as part of the process. I ./configured it with the prefix= argument so it would install into /sbin instead of /usr/sbin, and I did a yum remove iptables before installing it so as not to get in the way of the original iptables, but I'm wondering if this is really necessary - it's kind of annoying, because removing the original iptables removes the init.d script, deregisters the service, etc. If I don't, is it possible that iptables 1.4.1.1 might get overwritten in a system update or something, or will yum see that I've got a custom/newer version in there and leave it be?

I have been beating my head against a wall with this for more than an hour.... I purchased a new Ethernet Card to bump up the other side of my network from 10/100 to Gigabit. I previously had a 3c905c 3com card in there before. the chipset I purchased was a realtek 8169 Gigabit..... I removed the old card and put the new one in. Then I ran netconfig but realized that it was holding onto eth0 with 3com's MAC address, so I went and removed the /etc/sysconfig/network-scripts/ifcfg-eth0 file. did a service network restart no eth0 trying to start - perfect... I reran netconfig and configured eth0 with all it settings "Netconfig Did recognise the Realtek 8169"
I saw device not initalized when doing an ifup eth0 So I lsmod and saw the 3com module still running - removed the module rmmod 3com - and checked for 8169 - not running... modprobe 8169 and then checked.. bingo its running... service network restart - same error r8169 device eth0 does not seem to be present... delaying initialization. ok - eff it - ill reboot It came up same thing - did not expect it to change... checked /etc/modprobe.conf - i see its aliased... Verified all things are running... I really don't know where to turn... Im sure I could just call it eth2 but then im going to be rewriting all my iptables "firewall rules" and im trying to avoid that.... ** yes I know I could just use sed to replace all eth0 with eth2 ** but then im not learning why and what i am missing...
heres my output
Code:
[root@router etc]# cat /etc/modprobe.conf |grep 8169 && lspci |grep 8169 && lsmod |grep 8169 && cat /etc/sysconfig/network-scripts/ifcfg-eth0
alias eth0 r8169

On my old centos 5.2 installation, yesterday my system stopped. The only daemon working was the ping. Every other were not working ( http, svnserver, vncserver, ssh ... ) but yesterday morning everything worked fine! Since the system is headless, I rebooted the computer this morning. Then it never came back. I placed a screen on the computer and when the computer boots, I can see : loading grub stage 2 then I have a black screen with grub>
There is something wrong ... I'm sad because I moved in my new house and did not took the time to restart my backups ( in fact, I did not found the AC adapter for the external drive ) ... I downloaded the brand new centos 5.5 installation DVD and when I try to upgrade my system the installer tells me that the partition on 1 hd is not readable. Then I ignore the message but before getting to the partition manager, it tells me that the partition table for the lvm 00 ( /home ) can not be found and I have to reboot. Since this hard disk is the biggest ( 1tb ) and all of my data is on this one, I'd like to know what I can do to recover this data ?

View 1 Replies View Relatedi did make a raid server out of some old hardware and 2 new sata disks.setup is: 15 Gb ide harddisk as hda,a pci serial ata controller, with two equal sata harddisk on it (320 Gb each)did a minimal install of centos 5.3 on this (with a yum update after install).i choose for a raid1 configuration of the serial disks.on the command line fdisk -l gives:hda1 hda2, hda3 (swap), hda4 (extended) and hda5 (logical, data partition).added to thatdev/sda1 linux raid autodetect (the first sata disk)dev/sdb1 linux raid autodetect (the second sata disk).both sata disks only have one folder /raiddiskthe last line of the fdisk -l output gives:/dev/md0the size is as each of the sata's is (320 Gb), the listed heads etc. are not equal to those of sda1 and sdb1 (which are fully equal to each other).
as the utmost 'last line' of the fdisk -l output there is a line stating:"disk /dev/md0 does not contain a valid partition table"when i output the fdisk -l command to a text file (fdisk -l > whattheheck.txt) that last line is not in the text file, so centos seems to print it additionally to what fdisk -l brings up.my concern: what does that last line about md0 mean, and how risky is it to ignore it?(writing to the sata disks seems to be okay, both seem to have the same data on them)

View 2 Replies View RelatedNew Centos 5.4 64bit install on vmware esx 4, NAT net setup. I can ping/trace other servers on IP, do nslookup's on name..Ping(traceroute on name gets me "distination unreachable", indicating an ICMP issue, so I checked the network setup, all looks like usual.Well, except that my routing table lacks the 127.0.0.0 and 0.0.0.0 def. gw entries, as in this working box example:
192.168.9.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

0.0.0.0 192.168.9.1 0.0.0.0 UG 0 0 0 eth0
FWIW, during install, I did the usual basic firewall steps,including SSH.Tried with/without iptables, no change; no wonder given the lacky routing table. Sure, I can add what's missing to the routing table, but I'd like to know why it's missing; i.e. what I missed on basic setup, as I'm going to repeat this with a nof new installations (replacing SLES).
