General :: SFTP Server Port Blocked On Uni Network / Need To Change Listening Port
Oct 21, 2010VERY 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.
General :: Close Listening Port In Ubuntu 10.04?

Security :: IPtables And FTP When Server Listening On Non-Standard Port?
Nov 9, 2009I'm using iptables with modules ip_contrack_ftp to be able to use passive ftp. It works well as long as port 21 is being used as listening port. Is there any way to make it work when I configure my ftp server (vsftpd) to listen on an alternative port, lets say 21001 or something? The helper module only seems to be working properly with the standard port, so I was wondering whether there was a way to "tell it" that another port is being used? I mean, of course I make a rule in fw to allow traffic to the alternative port.
But once it's time to start passive connection, then the iptable module cannot handle it properly. I could solve the problem by making a range of passive ports in the ftp-server configuration and allow the incoming traffic to them, but then using helper modules doesn't make any sense. I just want to allow the traffic to the listening port and then want the ip_contrack_ftp module to take care of the rest. This is what I do today - but only port 21 seems to be working. Is there a way to do this with a non-standard ftp port?
Fedora Servers :: Syslog Listening On Port 514 For Both Firewall And IDS Logs?
Jan 17, 2010Currently Im having a syslog server that consolidate firewall logs on port 514 udp. Im also having a IDS device that I wish to push its logs to this particular syslog server so that I can retrieve my IDS logs on this server as well.
Is it possible to do so?Having syslog listening on port 514 for both firewall and IDS logs? If it is possible will the logs be recorded in a single log file?Or will it be recorded in a separate log file ie. firewall.log, IDS.log etc?? I wish to have them in separate individual log files or else there will be hard time segregating the log entries in a single file. Can anyone advice on how to achieve this??

Ubuntu Networking :: How To Determine Which Port Needs Opening
Aug 2, 2011I am unable to open my webmail on my small business computers (all ubuntu 10.04 LTS using a Billion router) but am able to access it from my home computers (also ubuntu 10.04 LTS but with a different router).
The most likely problem is obviously that the firewall in the router is blocking access. I know how to open ports in the router's firewall, but how do I determine which port or ports need to be opened?
I have asked my email provider, and that have replied that the port can vary and I need to get my technical support people to do it. Obviously they struggle to understand the concept of 'small business"!

FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.
