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"
View 9 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 6 Replies View RelatedI'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

Port 30000

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.

View 5 Replies View RelatedI 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.

When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.
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.
View 6 Replies View RelatedI am running OpenVZ.I wanted to use the VPSs IP at a particular port to load the Servers Web Pages e.g. The IP 88.88.88.88 is the VPS IP and 77.77.77.77 is the servers main ip.My files are on the main server at /usr/local/pages/
I want to load the page from the URL: https://88.88.88.88:8888
These should load the files from the main server at /usr/local/pages/ Virtuozzo a OpenVZ panel does it. So how is this going to be possible ? Will DNAT do the trick : iptables -t nat -A PREROUTING -p tcp -d 88.88.88.88 --dport 8888 -i eth0 -j DNAT --to-destination 192.168.0.1:8888

View 3 Replies View RelatedI am researching how to make an effective backup on Ubuntu Server. This server will have Vsftp, VPN, Samba stuff , many other added packages +many printers, many users + data. I know I can use tar for the data /u no problem. 1. I was testing tar on the /home directory on a few user directories. I then created a new directory and did a restore of the users directories on it. I noticed the /home/user owner and group were root. The files in each directory remained the same. This gave me concern. If I had a crash and had to restore these to a new HD. I would have to change these, what else would I need to change? 2. Since I have many config files, how do I back up them? I know I can do a dump, but then users shouldn't be on the system. The system files will change as they add users, printers, etc, and asking users to not work, is not really an option while dump is running. I thought I could do a tar on whole system. (cron late at night .. not as many users) Then in event of crash of HD.
1. Boot from live cd
2. format the new drive
3. tar back in the whole system
Will this work right? Is there something I am missing?
I have written simple application in cpp which listens on port 8080. But when I start the application and check the port it is listening on (using netstat -nap), I can see that the application is listening on port which is > 30000.
This port number keeps on changing if I re-run the application.Please let us know if I have to do any kind of a seeting so that application starts listening on 8080 port.I am using CentOS 5.5 (I tried same on CentOs 5.2)

I have a fresh installation of CentOS 5 I'm using for a server, and I'm having issues with port configuration. I have iptables running, and it started with no /etc/sysconfig/iptables file. I added a few basic rules (port 53, port 10000 for webmin), saved the file, and restarted the service. I tried connecting to webmin, scanned ports, and traffic was blocked. I set iptables to allow all traffic and restarted the service, and it still showed basically every port as being blocked. It seems port 80 and port 22 work for some reason, even when I tell iptables to block all ports.
I'm not sure what's going on here. Iptables is reading the /etc/sysconfig/iptables file, and if I use lynx localhost:someport it responds as it should according to the file. However, if I try connecting by IP, it's like there's some other firewall or something running that does whatever it's configured to do.....
A lot of activity is happening on our local server and I want to know which port is getting the most used and which daemon is using the port. I think it will be some modification of netstat command.
