So I requested a total of 5 to 6 times for a reboot from my DC. Whenever I try to start my AFP firewall, it just hang my server. Even after I reinstall AFP and start it, it still hang my server! Is there any log file where I can keep track of the problem?

A spammer (probably www.powerball.com) is sending spams using one of my email addresses as his / her "from" address. This hanged my mail server last week and it took more than 60 hours to solve the problem.
My host replied me the problem was "You have over 100,000 emails in your mail queue due to a large amount of Frozen emails that were either deferred by the remote servers or sent to invalid addresses repeatedly".
From this morning, my emails are blocked again. I can't send / receive mails using any of my email accounts (from this server). I don't know how long this will take again to solve the situation, and I'm afraid that this may not be the last time.
Now I don't know what to do. Ideally, a logical solution could be to delete any bounced mail automatically (I'm using nutsmail + squirrel mail).
My video sharing site has high traffic, alexa rate:3,000
My site has 2 servers to split the load. 2 servers share a mysql server. Using rrdns to load the balance.
Server A running mysql 5.0,lighttpd
Server B running lighttpd.
Server B connect to A's mysql database.
During peak time. B can not connect to A's mysql server. It says server not responding. But A still running fine.
When I check mysql log file.
/usr/libexec/mysqld: Forcing close of thread .....
And when run top, the load average is 20.
The spec of Server A
Intel(R) Xeon(TM) CPU 3.06GHz dual core.
2G Ram.
Here is the my.cnf
Quote:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
max_connections = 1000
wait_timeout=60
connect_timeout=10
interactive_timeout=120

query_cache_size=128M
query_cache_limit=2M
max_allowed_packet=16M
table_cache=1024
sort_buffer_size=2M
read_buffer_size=2M
My question, do I need another maching C to run lighttpd, and just keep mysql on A.
Or I can do some mysql optimization on A.
Also, if my site keeps going, can I have 1 mysql server and 5 http servers?
We are hosting a site on w2k3 server and every couple of days it just hangs. type in the url and it will not load, it timesout then u see the typical 404 error page.
We have about 150 websites hosted on the same server, it just happens to this one.
Restart the application and its back up like it's never been down, speedy and running smoothly. I have tried looking for memory leaks, i've put it in its own application pool and it still happens.
Our client is getting frustrated by this and so are we with ourselves for not being able to resolve it.
I have a VPS in which mails are hanging in Mailqueue. When I use these commands at SSH(iptables -D OUTPUT 2 iptables -D OUTPUT 1 ), every thing goes fine and mails are started delivering but after 8 or 9 hours same problem occurs.
So my question is:
Can there be a permanent solution for this problem?
Ordered a server from a reseller and they informed me that they are no longer reselling dealing with this company.
This was just after i had moved all my sites over to them after numerous problems with setup.
I had just paid an admin to do the transition........its a free site benefiting animal causes. So my budget is smallie
of course the TOS states no refunds....but they provided the wrong hardware on two occasions.....
im not sure if i have any recourse....
During downloading the files for the upgrade, it is hanging at downloading the following file:
plesk.msi
When I look at the C:ParallelsInstallerparallelsPANEL-WIN_11.0.9dist-msi-Microsoft-2003-i386 I see that the file is .tmp and cannot be deleted.
I do not know how to stop the upgrade, delete the .tmp file and download the files again.
I've got a client who seems to be having a problem with his e-mail on my VPS.
When he tries to download mails his browser(thunderbird) says 'Receiving one of 80' and hangs. The only solution is to go into webmail and delete some of the mails then try and receive them again. One thing that puzzles me is he doesn't have 80 mails in his account, he only have 33.
This isn't happening with anyone else who's using thunderbird and my VPS.
After the micro update, the database copy function started to hung even just for copying database with 4 tables with less than 10 rows of recrods. Although I followed the link below to remove the hung database copy and remove the unfinished database copied. URL....However, no successful database was copied at all even after the timeout was adjusted.
View 1 Replies View RelatedDo you recommend a software firewall when behind a hardware firewall?
All of our servers are behind Cisco ASA 5505 firewalls which we rent from Liquidweb. All are being managed correctly and setup to there optimal levels. With hardware firewalls firmly in place, do you still recommend a software firewall such as APF or IPTables (we're talking linux); in our opinion we see it as an extra administration overhead. If this is however untrue, we will change out thinking.
How do you modify a server's firewall? We have a dedicated server with WHM installed and it appears we can't get into mail.domain.com because of a firewall setting (our host disabled the firewall and it worked fine, then of course put it back up).

View 7 Replies View RelatedI want to install APF firewall on my vps server.
My server is OpenVZ based with hypervm.
But i dont know wich port used by hypervm and lxadmin and must be open in firewall.
I'm looking to colo 5 servers, 3 app servers, 1 db, 1 backup/sparedb. I am looking for something to provide a bit of protection in, and it seems like the ASA5505 is a good firewall, but I was wondering if anyone had any other recommendations?
I probably won't need ridiculous features, I wish it had gigE ports (I need to get a separate gigE switch for now, just for internal transfers+backups).
Is there anything else that might be a little cheaper, or do I need to upgrade to the 5510? Myself and one other person are the only people who would be VPNing to the internal server cluster, so we don't need massive connection rights.
I do not think I will be pushing 100mbits of data transfer, so I'm not worried about the throughput of the server.
What's the best firewall to use on a dedicated server? Maybe something free, or at a low cost - it's a necessary expense after all.
View 6 Replies View RelatedWe have a Dell 1950 server with WinServer 2003 which is at the moment unprotected and exposing our entire network to the internet. At the moment we don't have a hardware firewall and want to install a software firewall in the meantime for ACL. We could use the default firewall that comes with the server but apparently that's easy to exploit. I tried one called Kerio, however this particular firewall can't be configured from RDP because it needs to be active in order to input the IPs for it to allow. Any suggestions on a software based firewall solution that's easy to install and manage remotely?

View 6 Replies View RelatedI've found a dedicated server at a great price and plan to stick with it, my first ( already have 2 vps accounts ). I don't have the money for a hardware firewall. However, I do have a chance to renew a Kerio WinRoute Firewall license from way back.
Does anyone think this would be better than the default windows 2003 firewall?
A firewall will run me another $100. Is it worth it? Do any of you run a Windows server w/o a firewall.

Questions About Self-Managed Dedicated Server
View 11 Replies View Relatedwe had 2 Xen serverers in colohouse, each with 30 IPs yet.
Now we are going to purchase third server and started to think about renting small rack and putting own firewall infront of the servers.
Actual bandwidth is 5Mbits for both servers together.
We are thinking about to have something like this:
Colohouse-->Firewall<-->switch<--->Xen server(s)
With scenario we would like to add:
1) traffic monitoring per IP
2) traffic shapping per IP
3) firewalling whole segment of our public IPs
FW will get single IP and range of public IPs routed to that IP
4) be able to put one public IP for VPS on to any Xen server
What firewall and switch you will recommend for this scenario?
I have a server with Windows Server 2003 and for some days alguian is trying to enter using terminal server.
How I can block the ip of the attacker?
What firewall you recommend me to install in the server?
can anyone recommend firewall software for Windows 2003 Server. I'm aware it has a firewall on board, but this one doesn't allow me to specific access to specific IP address on the server, which are configured on a single adapter.
Also, I've looked into IPsec, which is my backup solution if I cannot find a decent firewall. Unfortunately, IPsec is kind of restrictive and not particularly stateful.
I'm looking for a simple firewall, which is not too expensive. This is only for one simple server.
I just uninstall apf and install csf firewall on 4 servers
There is a problem after that. 2 of the server actually was OFFLINE by 12 midnight sharp yesterday night. This is the second time (second day) it happens.
I went into the datacenter and
#ping yahoo.com
*Host not found*
#service csf stop
#ping yahoo.com
*Responding*
So how is this related to eth0 making my server offline by itself? Was it Iptable problem or Csf problem? or Kernel problem?
I have Windows 2003 Server on my dedicated server...
PLESK 8.1
When I go into the Control Panel -> Windows Firewall.
It won't allow me to open Windows Firewall to configure it.
I get the following error....
"due to unidentified problem windows cannot display Windows Firewall settings".
I have checked PLESKs control panel. And there does not seem to be a service in there for Windows firewall.
My Host suppose to have contacted PLESK about this problem but they are taking far to long to resolve the issue.
We are looking for good firewall and HIDS for our windows server
