If the server restarts, does the information in iptables get lost? I have seen a number of pages where people recommend readding lines or creating bash scripts to get it to work again. What about files like squid.conf, ncsa_auth files, etc.?
View 10 RepliesI recently installed a new Ubuntu PC that runs iptables and PSAD. I had the same script on another Ubuntu PC, but when I copied the script onto the new PC, I got this error. I don't remember where I found the tutorial for this, all I know is that this is the script (Edited for my usage):

I am using Fedora 10 and when I first installed my machine, I had a DHCP assigned address to my network card. Later on I decided that I wanted to give my machine more of a server role, so I switched to static IP using the system-config-network utility. What happened after that was that I did change the IP address and routing information, but DNS information gets lost at every reboot, so I need to type it back again.
View 5 Replies View RelatedI am new to Scripting. My task is to create a script that would pull the old server(unix) and new server(linux) information and should display all the task information for migration/cutover purpose to the other areas. We already have a script that gives information about ip, subnet, gateway and other information as follows:
#readip ad30db01
Server IP Subnet Gateway VLAN
10.x.x.x 255.x.x.x 10.x.x.1 100
There is a main server which has info about all the servers and we execute the readip from the main server which gets info about any old or new server. So, in my script, I am calling this script, and I want to display only few contents of the readip output as follows:
Hostname: (I should display the server ip from the read ip only out)
Subnet: Should display the subnet from the readip output
Gateway: Same
Vlan: Same

There are about 8 users, and the thing is they many times user rar or some other disk-demanding programs. What I've noticed is that sometimes server will go with load over 20 (I know that's not good ...) and it will come down in few minutes and everything is OK, but sometimes it just restarts itself. I would like to disable that so it won't restart
View 9 Replies View RelatedRecently, I updated the kernel to the latest version and also installed Ruby and the Passenger module for Apache. The server was fine for a few days.However, today, it's been restarting randomly (usually a minute after I can log in).I tried booting with recover mode so I could view the logs for a longer period of time, but that caused it to restart before even allowing me to log in. Now, all boot modes will just cause the server to restart right after the GRUB messages appear.Our server setup complicates things. We have a RAID-1 mirroring for the /boot partition and a RAID-5 (software) for the / partition

First, (for samba) how do I determine whether my computer "gets IP address information from a dhcp server on the network," and whether "the dhcp server provides info about WINS servers ("NetBIOS name servers") present on the network," and consequently whether a change to my smb.conf file, "so that DHCP-provided WINS settings will automatically be read from /etc/samba/dhcp.conf," and whether the dhcp3-client package must be installed?

View 10 Replies View RelatedWhen trying to install 11.2 from DVD, the user information I entered at the beginning of the install gets lost. I get to the Automatic Configuration step at the end of the install where the computer needs to reboot, and it asks for my user ID and password (it shouldn't do that). It won't accept the user I created (always says login failed), but it will accept root. That really doesn't matter, because the Automatic Configuration step has done anything, and I have a busted install. I've tried the install 4 or 5 times, but it is always the same problem. I eventually reinstalled 11.1 without any problem (though I did have to click Use Entire Disk on the partition section so it would delete the ext4 partitions created by the 11.2 install and create ext3 partitions).

View 6 Replies View RelatedI have a server located remotely that I'd like to protect by allowing access to only my IP address (on any port). Currently anyone can access the server using ssh, http, and any other services that my server is running. (The reason I need to protect it for now is that it's a test/development server and really only needs to be accessed by me.)
The downside of doing this is every time my desktop IP address changes (from where I access the remote server), I would need to update the iptables configuration. (This could be a hassle, but based on my limited knowledge it seems to be the best way to allow access from only myself.)
Could anyone share how to allow access to my server using iptables from only my IP address and on any port?
I'm making a clever backupsystem based on nfs and rsync.Basically, I export folders from the clients to a backup server, and the backup server processes them and makes backups.The backupserver mounts the folders during startup, but if a client restarts, then I guess it would unmount from my backupserver, right?What can I do to make it automount the folder whenever the client gets back up again?All the clients are static servers without much interferance, without any risk of external people tampering with them and without internet access. Security is not an issue, and any kind of shady compromisingcripts will do.However, installing software on them is tricky as I have to download packet for packet and transfer them via usb manually.
View 9 Replies View RelatedI want my server to automatically shutdown at 23:59 and startup at 8:00. The startup is handled through by bios but the shutdown is to be managed through cron. I thought I had this working, I actually swear I had it working because I thought the uptime command showed the appropriate uptime. I happened to be up and was streaming a movie from my server when at the time it should've shutdown it actually just restarted. If I run the shutdown -h now command by itself it works well but the scheduled command just restarts the server. Here is the what is shown when I enter crontab -e.

How would you make NIS user information override local user information on client systems? This is what I think is right? Add nis on the passwd registration file on the second line Is this correct?
View 1 Replies View RelatedI'm curious but recently I was troubleshooting some iptables rules to allow nfs clients access to my nfs server. What was strange was that I setup a tcpdump session on my nfs server so that I can see which ports were being requested. I ran several tcpdump sessions with the following filters in place.
tcpdump -vv src ip_of_client and dst _ip_of_client
tcpdump -vv src hostname_of_client and dst hostname_of_client
However, the only packet I ever saw come over the wire to me was the client host asking for a arp resolution. Anyhow, I finally just ran 'rcpinfo -p' and added those ports to my iptables rules and it worked great. However, I would like to understand how nfs works in case I need to troubleshoot it in the future. I do understand that nfs uses portmappers, would this explain the behavior?
In my server the iptables and ip6tables services are not running. But still i am getting some iptables and ip6tables related alerts on my /var/log/messages. My technical leader told me that there might be some mis-configuration in iptables configuration file. But i didnt see anything wrong.

I've been tasked with setting up a RHEL FTP server to mirror one we currently have. From what I've read, I need to install and configure VSFTPD and then configure IPTables. From what I've been able to come up with, I need to follow the steps in this article to install and setup VSFTPD. Is this a good complete article to follow you think?Also, how do I copy the iptables config from that server to my new one? I think that iptables on our current server only allows certain IPs or blocks certain IPs (not sure which), so I need to have it do that on my new server as well

I've set this up as a primary dns server, Bind is the only thing running on it, no gui, etc. I followed the default settings so I have a named.conf, named.conf.options, and named.conf.local file.
I have a log file I labeled as named.log in this path /var/log/bind. I'm using logrotate to rotate out the file.
My problem is that after syslogd restarts in the morning. My named.log file don't start logging info until I restart Bind. The new named.log file gets created and the old files rotate out and compress. All of the other log files in /var/log, syslog, messages, mail, etc, rotate out and compress like they should, after syslogd restarts.
I know that I could restart Bind using Cron but I shouldn't have to.
Below are snips of the files I'm using.
I named this one 'bind' and it's in the directory /etc/logrotate.d
