Hi List, My Mail/Proxy server has from time to time refuse to accept accept network connection. If I restart the network service, the service will again start to accept connection but after some time will again refuse connection. I use CentOS 4.5 with Squid, DansGuardian, Postfix. Please can someone point me what are the possible cause of this. Thank you. junji aisalen.wordpress.com Linux

Hi Friends, I am planning to upgrade my mail server from CentOS4.5 to CentOS5. By this, I also planned to replace my postfix mail server with Scalix although the community edition limit me to just 25 premium user, I think it is suffice for us with the remaining user as standard user (with approx. <> 100 users total). Is there a catch on using Scalix based on your experience. I see that

Hi, I just wonder if I can replace PIX firewall with machine having IPTable as my firewall. I want to control our firewall but due to the lack of knowledge in configuring PIX, i want to replace it with Linux or BSD. I do not have the time now to learn the complexity of PIX and yet I want to know what happening in my firewall and control it as much as possible. Do you think it is justifiable for

Hi, The Ping service in Nagios has "unknown" status which was previously OK, this happens after i messed up some of the files owner and accidentally change it to Apache. Although I restored most of the file permission back to Root, the problem above still appears which I suspect is due to permission. Does anybody have idea where to look at.

Hi, I just finished replacing my mail server with the new one from CentOS 4.6 to CentOS 5.1. The mail are running smoothly with user able to send/receive mail from Outlook using IMAP or POP3 and Webmail locally. My problem is that when I am outside my network like in home, I cannot able to access the Webmail. In my prior mail server, it is ok. Is there anybody here have clues for me to look for?

Hi, I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify. Is there a way to do this

Hi, Last year, I tried to installed and evaluate the following OSS web base trouble ticketing system. This is for me to track history on our IT related issues. Those that I tried are the PHP Ticket, DanPHPSupport, Epix Power Support, ruQueue, Ticket Express, OTRS, PMOS Help Desk and eTicket. From those, PMOS and eTicket are my top picks. I have problem installing OTRS the last time, so I am

>Firewall? What have you done to try and find out what the problem is? I disable firewall and SELinux on mail server machine and the PIX firewall where the machine connects to outside world allow port 80 and 443 just as before but still the problem persist. I will try to up later the old machine and will check if the web mail becomes accessible and then restore the new machine (this is in

I search from google on how to restrict user from sending mail and I did trial and errors for three days already but to no success. What I want to do is to restrict some user in sending mail while some unrestricted user will send mail to internet and intranet. I am able to restrict outside address (i.e. gmail, yahoo) to not send mail on restricted users but the vice versa I can not do. Is there

Hi, I had successfully installed CentOS 5.1 fully updated in old Fujitsu Primergy MS610 server. There was no problem except that during startup, I found many message saying "ohci_hcd 0000:00:0f.2: wakeup". Searched the internet and did what is written to avoid this to no avail. Anyone have ideas on how to resolve this? It seems that it was related to USB port which, I will not use

Hi. In order for restoration to work fine, I have to create a folder using the interface (e.g RounCube) which also creates the required structures. Then I copied the emailfile e.g xyz:s to /myrestoredemail/cur/ How do i properly create a folder with its structures(index,etc) without using the RoundCube web inteface ? Thanks CoolAtt

Hi All, Which is the best signalling to use when connecting an FXS inteface on a TDM400 to a standard telephone. I see that all examples use fxo_ks, but it is my understanding that kewl start is really designed for connections to the CO so that hangup etc. can be detected. So does it make any sense to configure a telephone for fxo_ks? Or should it be configured for fxo_ls? Regards Garry Taylor

Hi All, I'm not sure if this is a problem specific to samba, or to cups, or to something else. I have a samba 3.0.7 server acting as a PDC, and print server for my wonderfully overcomplicated home network setup. The problem is when I send a PDF to the cups server to be printed, it only prints the first page then the cups mgmt interface will say that the job is completed. If it's a
