I'm confused as to what protocols 50 and 51 are.
Code:
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
The '-p' option is not for a network port but for a protocol. I've never heard of 50 and 51 protocols.
how do you configure your network time protocol to use a specific time server ip address
View 2 Replies View RelatedI am working as a system administrator, i got challenging work from my team leader i.e., configuring network printer in redhat 4.2/centos 5. Initially i started with redhat linux 4.2. Unfortunately i didn't get any default man pages. I downloaded the rpm package mit-lprng.3.8.27-10-rhe4.i386.rpm and ran it. I got man pages of lpd but i couldn't able to start lpd services. then i downloaded the lpd daemon startup script from this site :Now i could able start lpd services.In server system i have configured the printer locally (shared and used LPD protocol). In client system i am unable to take test page even though it is connected to desired print server.Even some times it shows "remote host cannot accept control file(data file) 32

View 13 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.

I recently purchased a Dell Vostro v130 which came with Win 7 pre-loaded. I've been using it for a few weeks with no problems, but now I'd like to install ubuntu studio. I made it through the the partitioning part but now I'm getting a networking error: "Network autoconfiguration failed. Your network is probably not using the DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly."
I've been using the wireless connection in win 7 without any problem so I don't know why I'm having a problem now.

My server is going to be running Gentoo. I also need something where i can access it over the internet(and I'm using dyndns for my internet access(acessing from a outside machine)) with encryption and little hassle. I need the ability to be able to mount in finder and multiple users to be able to open a file.

I run (trying to/have to) multiple TOMCAT servers.
I am trying to have each tomcat instance listen to on separate IP address for example:
What i am trying to do is to redirect
a) tomcat 1 -
a) tomcat 2 -
And so on.
I know that it has to be possible.
I do have just eth0/
Is is it possible. Do I have to create "vittual interfaces"? eth0:1, .......... and do redirection ?
"Server" has got just single interface - just 1 ethernet calbe goes to that server. I am planning to have 10-15 tomcat's on that server (I have to unfortunatley) and each has to run on port 80
Is it possible to "grant" permissions to normal users to run app on port 80 - that would solve me lots of problems if impossible to redirect.

I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol.
I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour :
In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame.
In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog.
I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.
