I go in using nano /etc/ssh/sshd_config I change the port number.. I then restart ssh service restart.. I then run netstat -tupln and it still shows ssh as port 22!i am not sure what I am doing that is incorrect.Do I have to remove the # < ? I go to redit it and its still showing 2222 nano /etc/ssh/sshd_config ?
I want to change my ssh port from the default 22 to something else. I did the following: vi /etc/ssh/sshd_config; uncommented Port 22 and changed it to the desired port number. After that I run service sshd restart for the change to take an effect. Now, when I want to login into the new port I receive this message - Network error:Unable to route to host. When I change the port back to 22, I will be able to login again.
i need to change ssh port on the servers including centos and ubuntu when i make changes to /etc/ssh/sshd.config and change the port to something else restart sshd then i can determine that port 22 is not working but ssh does not connect to new port it says "no route to the host"
VERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
I edited "sshd_config" file and changed port 22 to a new port. After I restart ssh, it listens on port 22 and the new port. How can I disable SSH to listen on port 22? I'm using Debian.
I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?
i am trying to edit sshd_conf files to change the "#Port 22" to "Port 22" from a script.
I have tried this many different ways.
sshs1='s/#Port 22/Port 22/g' sed $sshs1 /home/l/Desktop/test
the reason i have it as a string in this instance is because $sshs1 gets a variable, but im not working on that right yet. I've tried changing the ' to ` and ". this is what i get:
sed: -e expression #1, char 7: unterminated `s' command sed: -e expression #1, char 8: extra characters after command sed: -e expression #1, char 8: extra characters after command " sed: -e expression #1, char 7: unterminated `s' command
i know it may have to do with my regex, but i cant seem to find a decent tut.
Can anyone here point me to a walk-through or discussion of how to use Webmin to set up port forwarding/NAT on a dual-NIC Centos 5.3 box? The layout will be simple:
Internet --- NIC1 [CentOS Box] NIC2 --- Switch to other PCs
We have a BUNCH of exposed services that are on special ports -- for example, to connect to one machine, you go in with [IP_Address]:12000, and to connect to another, [IP_Address]:12002, etc., etc. We're currently using OpenSuse 10.3 on this box, and YaST makes this criminally easy (you give it the incoming port number and the destination IP/port numbers and it just works). But OpenSuse 10.3 is nearing EOL, we're buying a new machine, and I'd like to use CentOS on the new one.
I've read the sparse Webmin documentation in their Wiki, and it leads one to believe that you simply insert a "NAT" rule. But there's obviously something they're leaving out. I *am* opening the ports in the firewall. But when I log in to [IP_Address]:port, it just times out. The port forwarding never occurs. The test in this case is SSH, and I know that SSHD is working properly because I can log into that machine just fine from another PC on the same internal subnet.
i am not able to port 8080 on my CentOS VPS server.I have followed all the instuctions as mentioned on iptables wiki page.Also I am able to telnet my ip address and port number, But can not access from browser.
we are going to install ASTERISK remotely, hence the port 22 in the server has to be open ,Can somebody reply me with exact commands?I tried these commands and got these results
Command : cat /etc/services | grep xxx Result : No Such file or directory Command :netstat -nan | grep 22
I have a program which requires running on port eth0. My current connection is named eth7. how can I change this? I went to /etc/network/interfaces but did not see the connections for eth0 or eth7 in that location. I also tried to change it in the "Network Manager" but that just broke my connection and returned errors. What Can I do?
When setting up a new pop3 accounr in evolution, I dont see any option to change the port, my pop3 server requires port 110.Is there a way to check or alter this in Evolution
I wish to use the VNC server built in to the Ubuntu to easily access it from other computers on my local network. I need to skew the VNC Server port off of the normal 5900 to something else because I am using VNC to access several computers (sometimes simultaneously) so each VNC server needs to be set with a different port #. At this point it is all local subnet connections with no incoming internet access and I am not worried about security.
I have Linux system with 6x500 GB sata drives on LVM. I want to change 1 of the disks with larger - 1 TB. I don't have available free sata ports, so I'll add pcie sata controller. I'll add the 1 TB disk to the pcie controller and will use "pvmove" to transfer the PEs from one of the 500 GB drives to the new 1 TB. Then I want to remove the 500 GB disk from the LVM. I want to remove the physical disk from the box and to place the 1 TB disk on its place. But I don't know if the LVM will recognize the disk? I want to remove the pcie controller from the box because the motherboards sata controller is better.
I am using Fedora 10 and I need to change the defaults that get set on the serial port.I know how to do what I need to in Windows, but I can't seem to figure it out in Linux.

I am looking to set up a system that will bring in an e-mail on a port like 4082 then sent it out to a standard e-mail port. this is a fire wall issue. I am looking for the best software I can use on an Ubuntu-Desktop platform to accomplish this and an idea on how to set this up?
I want to do a simple port redirect, i.e. whatever comes trough whatever interface on port AAAA will get redirected to port BBBBI thought that iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport AAAA -j REDIRECT --to-ports BBBBhowever it doesn't work, e.g. nc -v -w2 -z localhost AAAA gives:
nc: connect to localhost port AAAA (tcp) failed: Connection refused while nc -v -w2 -z localhost BBBB
but I'm not seeing anything from a GPS receiver in NMEA at 4800 no par 1 stp I know that was working about a year ago. I think udev was not helping ,as I was getting permission denied to the com port, I added myself to group dialout. and no message on startup now
I need to be able to talk to a piece of kit with 9600 baud and nothing. I have win32 s/w to drive it , but it falls over in wine. My laptop still has win7 on it in a tiny partition but no 9w d connector and I'm waiting for a USB converter cable. Too many variables ! I'd forgotten all the hassle of having to install drivers just to get basic things running. But as the stupid thing couldn't manage using the driver for my NIC, I was stuck with hyper-terminal, and nothing from the GPS board @4800 or another piece of equipment running at 9600. I suspect the com port on the new mobo doesn't wan to play
I am playing around with transparent proxies, The current way I am doing things is the program makes a request to a computer on port 80, I use
Code: iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy) so I want to do something like
Code: iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong,
I will be setting up a web server at my house. It will be a simple page for my family to keep in touch and maybe some other stuff. Here is the problem: I believe my ISP blocks port 80. So when setting up the firewall and it list the normal port 80 am I able to edit to say 8080? I have a ddns already setup for my router and I am waiting for an email back from DynDNS.com on setting up a new domain to forward to my already setup hostname. I just need to get everything redirected to another port beside 80.
