I have to create a structure in which there is a client, a server and an authentication authority.
The authentication authority verifies the identity of both the client and server before they can communicate, so that the client can access the content offered by the server. Everything must be made using HTTP with SSL (HTTPS).
For now I have installed xampp on my pc with ubuntu, I performed the initial configuration and was able to view a test page locally hosted by entering the URL of the virtual server "www.server.it" (added to the configuration of apache2).
I need to clean up the .spamassassin directory for all the accounts on the server. The Bayes files are getting too big and causing mail handling issues.
How would I do that?
I assume this won't work - and don't want to try it until I hear a little feedback:
rm -f /home/*/.spamassassin/*bayes*
Basically, I need a command that will do what the above command looks like it would do - I just don't think the wildcards will work in that manner, and don't want to try it for fear of deleting items outside of the .spamassassin directory.
I'm running CentOS 5.3.x with cPanel/WHM - if it matters...
And feel free to suggest other spam blocking software - but we've gotten rather good at tweaking SA to get the job done. Just this annoyance of the bayes files growing continuously is a pain sometimes...
I've been with RockMyWeb.net for exactly one month now, and I want to share my experiences. This is a one-month experience, so it will be mainly about new purchase and initial support. This is a quite long post, I wasn't really considering to write that long.
I'm a shared hosting provider in local language. One of the websites I host has grown too much to be on a shared server. It didn't even fit on a standart VPS with 256 MB guaranteed, 1 GB burst ram. So we decided to go with VirtuallyDedicated, [url]
with the plan 1.5 GHP, since it was better than a dedicated server with pentium-4 processor and 1 Gb ram, and was cheaper. The website being hosted is www.trforumcu.com, along with a dozen of small websites.
Purchase: I requested a custom quote, with cPanel and management, less diskspace. They prepared the quote within 3 hours, I paid within 24 hours, they set up the VPS within 12 hours, including initial management. The process was painless.
Initial support: We had some requests about the VPS within the first 3 days, before moving the websites. The tickets was being responded within 2 minutes, some being even within the same minute. That is the fastest response time I've ever got from a provider (I've been with 6 different VPS providers, as far as I remember.) It looks like someone is always waiting for tickets at any time. My tickets were usually being opened in their nights, due to the time zone difference between us. I'm very satisfied with their knowledgeable support.
One point about their support is that they act as if the customer is their friend. I mean, They don't send this reply:
Quote:
Hello,
The issue is being worked on.
Best Regards, Blah Blah Customer Service Represantative RockMyWeb.net
Instead, they send this within the minute:
Quote:
Hi, I'm having a look at it right away.
I, myself, actually use the former type of reply to my own customers. But the latter was quite nice, considering they are sending it right away, and start working on the actual problem within the minute. And they are solving the problem, too.
Support within the month: After initial configurations, we had some problems. Our website was using too much resources, and the server needed to be optimized a little bit. I opened a ticket. They replied 4 times, without my reply. They informed me about the process well. After 4 replies, they said the server should be fine now.
After 2 days, they sent me an email, asking if I'm satisfied with the optimization. This is the first time I'm getting an email from a provider after some time, asking about my satisfaction.
We also had a cPanel licence issue (cPanel suddenly forgot about its licence, and started saying "cannot read licence file"). This was solved within 36 hours. They said the problem needs to be fixed by cPanel support staff itself, and their support over weekend is not the best. They kept updating me every 12 hours, saying they are waiting the cPanel staff. After 36 hours, the issue was fixed.
About their system: Their VPS technology is different from my other VPSs with other providers. They don't use Virtuozzo, they use some kind of custom system (it doesn't seem to be VMware or like). This is the only thing I can complain, I was used to VZ and their custom panel is quite different. They provide VPS restart utility, and this is actually the only thing I need from a VPS remote panel.
They don't provide equal-share CPU, they allocate guaranteed CPU. This was very important for us, because the website we were hosting was being kicked off the VPS providers due to high CPU usage. With rockmyweb's allocated CPU, we are not interfering with other VPSs on the system, and we feel quite more comfortable. Also, we have 1.5 processor cores guaranteed, much higher than any other VPS providers will provide for this cost.
Their backup system is also satisfying. They charge 0.25 per GB backup used, not allocated. So I don't pay for unused backup space.
Overall, I'm satisfied with their service, and very happy with their support over the first month. I'll update this topic with additional information and comments (both positive and negative) over the time.
With the dedicatedplace.com ongoing saga, I'm looking for a new dedicated server. I'm considering Sago Networks [url] Anyone have any experience with them?
I am interested to setup two Ironport appliances in my company network. As the current company is about 120 users, and each user send and receive an average of 100 email per day (including newsletter, signup, etc) it’s about 12000 email a day.
I am interested in :
For the mail side of the company, I am thinking about an Ironport C150 and for web filtering, I am thinking about S350. The current company outgoing banwidth is 60 Mbit/s at peaks, but I want to be able to be able to continue to use it with traffic up to 200 Mbit/s, as we will maybe take some server in the company network in a few months.
Some questions :
- Is it really « setup and forget » appliances (except monitoring them)?
- Are they hard to setup and configure?
- Do they support many email languages?
- What is the price for both appliance, like around 5k each, 10k each?
I would like properly address Matt Ayer's (WiseOne) continual claims that user created swap in xen can lead to disastrous situations. This doesn't make any sense from a Kernel point of view. Linux kernel treats Swap not as a additional memory, but as auxiliary storage, and will use it only sparingly. So a larger than ordinary swap has effectively zero impact on performance.
Quote:
I just don't have the time. Try this quick though. Create as many 64MB RAM Xen VPS's as you can, make a 1GB swap file inside each VPS, run a memory hogger, and then finally watch your system die due to horrific disk I/O. Not fun, I'll tell you that.
Conclusion: User controlled swap in a shared environment is a very, very, very bad thing.
Now let us assume there is a hostile user who is egregiously bent on creating excess disk I/O for the host and has purposefully hired vps to enact his revenge on the provider. Further assume that, for this nefarious purpose he has taken a 64MB xen and is running a full 1GB real memory allocated workload (To get create such a load itself would be difficult unless he writes his own programs to do this). Now note that, for the offending vps, the impact of the disk I/O is at the memory level, while the impact on the host is at the disk level. So very trivially, the vps would be so crippled to make it pretty much useless much before this starts having significant effect on the main server. And if engendering excess disk I/O is the sole purpose of user, then all he need to do is write a program to consecutively load and free all the files in the entire harddisk. This will create worse disk I/O than the convoluted method of using large swap. And the latter can be done on both virtuozzo and Xen--though I think in recent versions both have methods to throttle disk I/O.
The problem that UnixShell ran into with Xen was owing to their use of Snapshot, which is something that's prohibited, unless of course, you are running on a desktop with a single virtual machine. LVM snapshot will exactly double the disk I/O. The real problem that the usage is insidious and will not affect the actual vps that's leading to the excess load, but will affect the entire server as a whole.
Xen does have some drawbacks, but it can have all the important features which most providers here think are unique to virtuozzo.
Considering skipping VPS and going to a colo setup for a handful of sites. Nothing major, so the server will be very entry level, but with redundancy in mind (software RAID1 and 2 nics). But I have a few basic questions:
How good is hot swapping in Linux? This was very hard to me to find out online. I am getting a 1U rack with a hot swap backplane and 2 SATA drives. I won't be using any commercial software with my setup.
How does redundant NIC work? This is new to me and am wondering how this is setup.
I think I can shop around NYC for a 1U slot for around $40 a month. I don't need a lot of transfer, but would like a decent pipe. The thought of 1Mbit sounds unattractive (transfer is around 100KBytes/s, right?). How much would 10Mbit cost? I found some quotes but they seem way too much (I could be wrong).
I'm running the latest port version on FreeBSD of Postfix, Spamassassin (Razor & Pryzor), ClamAV, and Amavisd-new. I haven't gotten any spam for a while. The 2-3 days including today i've been getting 10+ spams per day. This seemed to happen after the update of spamassasin recently.
Anyone else experiencing this? My rules are pretty quick, at spam-score "5" I reject the mail.
I installed SpamAssasin and set it up in DA, I also use Spam Filter option in DirectAdmin (DA).
The problem is that if someone send me an email which contains any adult word in the body and a regular subject then it will not go to the Spam box, but if that email contains any adult word in the subject and no matter the body has adult word or not it will go to Spam box.
How do i send all the emails contain adult word in body to Spam box?
Hi i'm trying to use spamassassin from each user using .qmail from each mail user but i can't it dosen't works. Also i wish to know if i have any rule on spamassassin to check some words like sex viagra ,etc and if it's found it will delete it.
here to install spamassassin but however have a few questions as im new to doing technical things in ssh.

On step 3 of the tutorial, we are asked to change things in the /etc/exim.conf file, what is the proper command to navigate to this file and how to replace those text?
Quote:
The global spamassassin config file is in /etc/mail/spamassassin/local.cf
You'll want to make sure that you have the correct call to spamc in the spamcheck transport in your exim.conf: transport_filter = /usr/bin/spamc -u ${lookup{$domain}lsearch*{/etc/virtual/domainowners}{$value}}
For the lines i quoted, im not sure what i have to do here and how to do it.
Lastly how do i know if im installing latest version of spamas and how to test weather it is working against spam?
some good hosts that use more than just SpamAssassin (SA) for their spam filtering?
For instance, MediaTemple uses the Cloudmark plug-in, which greatly improves the stopping of spam. SA out of the box is horrible; and yes, I realize that with some tweaking it "can" be good.
I am setting up spam assassin white list and it says I can put *@domain.com so does that mean it will white list everything from domain.com ?

I am using cPanel 11 one of my Linux server with O.S. as Fedora core 4. For one of my websites I had enabled spam assassin a few days before. But now I want to disable it but not getting any option to do so.
there is a quota problem , i have checked my server
home/username/.spamassassing
.Spamassassing directoy using much Space .
would you please let me know , what is that dirctory doing ? and what will happen if i will delete all the files in the directory (Specially : auto_whitelist)
I have a dedicated server. It is a Fedora Core 6. It came with "Plesk 30 domain license". However, this license of Plesk doesn't have SpamAssassin enabled. In order to get the license with SpamAssassin, it costs an extra $30 a month.
I believe SpamAssassin by default is in fact installed on the sever, but some of my users are reporting that they are getting Spam. How can I check is SpamAssassin is running? How do I configure SpamAssassin to filter spam on all the e-mail addresses that are created in Plesk?
I want to setup Remote Spamassassin for Smartermail server. I want to the setup the spamassassin on a linux box. Can anybody help me with this as I am not getting any definitive guide for the same?
The problem I currently have is that all e-mails tagged by SpamAssassin as spam are deleted even though they are supposed to be moved to a different "probably-spam" file. In addition, I'd like to use the spamc + spamd configuration and I'm not using it now.
I tested that procmail is installed on my CentOS 5 server that's also using sendmail.
yum remove spamassassin // In case it is pre-installed. It was the last time I did this.
// Download it at spamassassin.apache.org: wget [url]
tar xvfz Mail-SpamAssassin-3.2.3.tar.gz
cd /Mail-SpamAssassin-3.2.3
perl build/check_dependencies // Checks which perl module dependencies are missing that need to be installed before proceeding. Then install them
perl Makefile.PL
make
make install

I figured that this might be a permissions problem but what I can do without risking security?
