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 # < ?

View 18 RepliesI 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.

View 1 Replies View RelatedVERY 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

View 1 Replies View Relatedi 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

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 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've just had to change the MOBO and trying to get the serial port working, I see from previous posts there are some problems lurking in the past.

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've got 10.04 on a headless server on a home network. I've edited /etc/ssh ssh_config and changed line 39 from:
# Port 22
to:
Port 30000
I then
user@server$: sudo /etc/init.d/ssh reload
from the host
user@desktop$: ssh servername -p 30000
ssh: connect to host servername port 30000: Connection refused
What am I doing wrong? I've also tried completely restarting the computer.
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.
