I am using csf to secure my server. I want to open the ssh port for certain ip only. So I edit csf.allow and add the following line:
tcp:in:d=22=192.168.0.100
Then restarted.
But I can still access the server from IP addresses other than 192.168.0.100. Anyone know how can I restruct certain IP address to access certain port?
I seem to have a strange problem (I am hoping that if I fix this, it will fix another problem I am having).
For some reason (I most probably did by accident) when I run the command lsof -i tcp:80. The information that comes up says that my IP address xx.xxx.xxx.172 is being used to listen to port 80. Yet the IP address that was asignned to me is xx.xxx.xxx.171. I am wondering how I would go about removing wrong IP address so that the right one is listening to the correct port.
I am running centos OS.
Have to type the full address with port number....

View 1 Replies View RelatedI have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?
My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively.
- the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11
- the external ip addresses resolve to the above internal addresses
- the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
Code:
<VirtualHost 192.168.10.10:80>
...
ProxyPass /app http://app_server1:7777/app
ProxyPassReverse /app http://app_server1:7777/app
RewriteRule ^/$ /app/app1 [R,L]
...
<VirtualHost>
and
Code:
<VirtualHost 192.168.10.11:80>
...
ProxyPass /app http://app_server2:7777/app
ProxyPassReverse /app http://app_server2:7777/app
RewriteRule ^/$ /app/app2 [R,L]
...
<VirtualHost>
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?

I am using virtuozzo firewall to secure access.
I enter 58.27.175.211/255.255.255.0 for Source Address and Netmask for port 22.
But still I can connect using 58.181.103.217 or 58.27.151.120.
Second is it possible to enter two different ip address in source address?
I just bought a new ip address and want to setup this new ip as my server's main ip, making the 'existing main ip' as the secondary ip.
Which means, this new ip will be the server's default ip address for all services, including when connecting to other server.
I'm using CentOs 4.5 and swsoft's panels: HSPcomplete & Virtuozzo Power Panel, and Webmin.
I want to redirect a website to a particular URL so that the address bar shows the same URL and not the destination URL. I know it is possible via URL masking, however, I want it in such a way that whenever somebody clicks on any link in the website, the address bar should still show the original URL. To put it in simple words, Suppose I want to redirect [url] to [url]. Now if there is a link named contact/index.htm and somebody clicks on it the address bar should display [url]and not redirect to [url]
How can it be possible using URL Rewrite method in .htaccess file?
The problem usually goes like this:
- I can't access the webserver
- I'll try to restart httpd, and I'll get
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:443
To fix this, I run
[root@www1 ~]# lsof -i tcp:443
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
perl 11307 apache 4u IPv6 476943447 TCP *:https (LISTEN)
There is always leftover process that is causing the restart to fail. Once i force kill the process, I am able to restart httpd properly.
Now it is ok if this just occurs once in a while, but this problem keeps repeating itself almost everyday at 4am server time (cron time?). What can I do to permanently fix this?
I am using proftpd...How do i instruct that the server don't listen on high ports 49152-65534 but only to 21?
The reason is because my client's firewall setup is very strict and i need to give a good reason to open those high ports. Right now, i can ftp to port 21 only but can't do nothing more than that coz the higher ports are blocked.
i now have root access at a site i manage and the previous admin has set up a different SSH port.
I think this because i get " Connection Refused " and that user has access for SSH.
When restarting my SSH services i recive;
Quote:
sshd has failed, please contact the sysadmin.
And from looking that error up it means the port has been changed.
So i have WHMC access and all other root passwords etc, but how can i find out the port?

I'm a bit new to this, and I wanted to host my server on a VPS. I tried connecting, but that just didn't work. Do I need to portforward the VPS? Sorry, Like I said, I'm a bit new.
View 6 Replies View RelatedI know this is a bit of an odd question but I have a VPS which has port 1189 open. Is it normal by default to have this port listening on a OpenVZ VPS under HyperVM? or is this something a little concerning? Never noticed it before, just checking I don't want any illegal applications being hosted on my server by clients.
It's most probably nothing to be concerned about, just wanted to double check.
