I have some problem getting masquerade works, but no luck. I created a cronjob that do a backup which will notify me by email. I was able to received the email with from "root@domain.mydomain.com" I want to change this to root@mydomain.com, I tried do the masquerade and it does not work.
View 6 Repliesl have been trying to enable masquerading in sendmail. I've started from scratch. Here's what I did:
1.My Mail Server name is "ids.com" and local hostname is "server"
2. When I send the mail from my user to other user. The mail goes with user@server
All this allows me to send mail from all of my computers. Now, to get masquerading:
3. I have MASQUERADE_AS(`ids.com'), MASQUERADE_DOMAIN(`ids.com'), and FEATURE(`masquerade_entire_domain'). I also added "ids.com" to /etc/mail/local-host-names to be able to receive mail addressed to that domain.
This masquerades mail originating on the server, but still the mail from the other computers has a "From:" line of the form user@hostname.
I have set up OpenVPN Server on a VM (Ubuntu 10.10) running virtualbox bridged to the host. Everything is working fine excepts the fact that I cant seem to be able to assign internal IP (VPN Server) to client connecting. Let me explain: All my clients are connecting and accessing the internet without any issue. Where I have an issue is that all my clients come out the other way on the internet with my server ip address which kind of defeat the purpose. Is there a way (keeping in mind that I am running the server in a VM) to have all my clients accessing the internet with an IP provided by the VPN Server?
View 4 Replies View RelatedI have a Centos 5.5 Server, Servername is CentOS1. It has a Forum and a HelpDesk. The Help Desk software SENDS and acknowledgement to the user and emails to all the people on the support desk. Users can reply to emails only by accessing the helpdesk NOT by mail. Thus the server is configured to only SEND mail and not to receive any mail at all.
Mail Server is Sendmail.
Hosts file reads : -
# Do not remove the following line, or various programs that require network functionality will fail.
127.0.0.1CentOS1.tech.xxxxx.com CentOS1 localhost.localdomain localhost
::1localhost6.localdomain6 localhost6
There is NO MX Record because this server receives NO mail, it's send only. Unfortunately, the mail it sends has a From Header which is @CentOS1.tech.xxxxx.com. I want it to send from @xxxxx.com. I've read all the howtos on Masquerading and I've tried many, many things, but with the same results. It will NOT change the From. I had it working perfectly a long time ago with a SuSE server, but I can't for the life of me remember what I did. I know I also battled a bit.
The last few lines of sendmail.mc read : -
LOCAL_DOMAIN('localhost.localdomain')dnl

I've tried each one of the MAQUERADE_DOMAIN in turn, none of them work and yes, I have remade it.
Have a router running OpenSUSE 11.3. I have 3 interfaces
eth0 192.168.0.0/24 - local network
eth1 - The Internet if
eth2 - Citynet
I have configured routing and it works. I can browse the Internet from local net. However, I want to connect to my workstation (192.168.0.3) from Citynet interface. I've made masquerading rule in Yast it works just fine like a proxy do (on 192.168.0.2 local server). Now I need to run VPN server in my local net to connect from Citynet interface, and I have problems with it. I've configured pptpd on the router and it work for local network and I have a vpn server under Windows on 192.168.0.2
So my questions are:
1. What do I need to do in yast to allow vpn (pptp) ftom eth2 to 192.168.0.2?
2. What do I need to do in yast to allow vpn on router?
Some how I succeed to make redirection to 192.168.0.2 and it worked, but I've tried to change it to router and can't get it work again.
In all these cases client has the next message:
pptp[109]: LCP: timeout sending Config-Requests

I mean would I need to logically seperate out a series of passive ports and then open them using my custom routers NAT, so each passive port goes to its own virtual host as such? Just a bit confused about what the next steps would entail I mean I don't have any firewall on my Linux box, don't see the point since I use pfSense and an IPS/IDS and it's never been hacked since!
How to Nat. I wanted to be able to resolve something like
ftp.myfirstdomain.com to 192.168.0.2
Then ftp.mysecond.com to 192.168.0.3
Just as a random example, I know these cannot be done using name based virtual hosts like in Apache. But I got this working internally using my LAN connection and the 2 IP addresses above, with Bind DNS pointing the dns's to those 2 ip addresses respectively. This worked, yet when I tried connecting from my work place to transfer some files, it kept going to the default user's home directory. Just wanted to get this project finished, 2 domains and one public facing IP address.
first of all, ill provide you with the package name i got [URL]...i went to /usr/src/redhat/SOURCES/bwbar-1.2.2 did ./configure ; make
then i get this problem : [root@server bwbar-1.2.2]# ./bwbar ./bwbar: /usr/local/lib/libpng12.so.0: no version information available (required by ./bwbar) i have installed libpng & libpng-devel
[Code]...
after looking around a bit i thought it would be better to get the sources from kernel.org directly and try to compile that one, but then i found it to have the exact same error. would be very nice if someone could direct me to a solution for this. i have the bwbar already installed on another server which runs CENTOS 4 , i installed it there AGES ago , so i dont really remember what was my method back then.
the CENTOS 5 server dose not like me installing bwbar on it for some reason. maybe its bwbar's fault?, im no coder so i hope anyone that got a clue could check this out for me.
I installed the latest version of Centos 5.4.It came with Xen version 3.0.2 I think.I am running it on a Dell R510. It supports hardware virtualization.I was able to virtualize Windows XP and Windows 2003 server on it by selecting the install from DVD option.I was having problems trying to get a PCI DekTek card seen by the virtualized Windows domains so I tried to upgrade XEN to 3.4.2.I used the repos available from Gitmo and it went easy.
The only problem is now that when I try to create a "New virtual host" it only allows me to use HTTP, FTP option and not the iso or DVD option. They are greyed out. I was wondering if anyone has had this problem and might know a work around for the Xen 3.4.2 problem. Perhaps a better location for the kernel or something.

I turned on the memberof plugin, here's the section from dse.ldif:
I'm currently messing with the value on memberofgroupattr. The only thing that seems to do anything is with it set the way above, in the error log I get:
So if I'm understanding, it's trying to mod the user entry and the attribute isn't allowed.
Setting the memberofgroupattr to anything else gets me nothing noticeable. ldapsearch isn't showing memberof:
I've run the fixup-memberof.pl in /usr/lib64/dirsrv/slapd-hostname and I get:
I'm using ldapadmin from a Windows box to assign/delete people from groups. What I'm a little confused on is the difference between a group and a groupofuniquenames. I also see a difference when using the web gui (directory server gateway) in users. The gateway creates and entry while in ldapadmin I'm creating users. Not sure how that factors but the memberofgroupattr relies on what object class it is and I'm obviously trying the wrong things or something is busted elsewhere.
The error log isn't showing any other errors.
I can restart dirsrv just fine, nothing funny in the log when I do that:

vsftpd ver: vsftpd-2.0.5-12.el5_3.1
I installed vsftpd server in one of my servers using "yum install vsftpd" command. NFS server is running in the other server and mounted as "/data" in this FTP server. root in FTP server has also root authority in NFS server. All the files and sub-folders under "/data" in FTP server have 755 or 766 mode. Even I modified vsftpd setting to allow root login.
When I login as root to FTP server with FileZilla client, I can see all the file list in root home directory and move to /data directory. I can download any file in a local HDD but I can not download any file in /data directory.
I am trying to figure out why yum on my server isn't working.Whenever I run a yum update it fails with a segmentation fault.

I run mysqld on another server. I just switched to another dedicated server now, and i'm having trouble connecting to the mysqld server.

However, if i run the script from apache ( http://localhost/connect.php ) it returns this: Can't connect to MySQL server on '(mysqld real ip)' (13) Mysql connection from another server(old httpd server) works perfectly, so it's not from the database server.
View 4 Replies View RelatedCentOS 5.2. Openldap server-2.3.27-8.el5_2.4 I'm trying to get the server to do two things. One is allow authentication--that is, if a client is configured to use openldap for authentication, it should be able to access this server.
In other words, on machine_2, a client, doing getent passwd (as a quick test) will show the users in the openldap database. The more or less out of the box configuration works for this. However, as soon as I start trying to add ACLs, it stops working. For example, I want to restrict access to an address book which is also in the database. So I have
access to base.dn(changing base to subtree makes no difference) "ou=addressbook,dc=example, dc=com"
by users read by anonymous auth Now, even though this is just the address book, after that, an ldap client can no longer get the names of users in ou=People, and using the ldap server for authentication doesn't work.
I don't understand what I'm missing. ACLs are supposed to work first match wins. *IF* I add under that, access to * by * read, it will work, but the address book can then be accessed without a bind dn.
I am not sure what I'm overlooking. If I put in any sort of access control, the only way that clients can continue to use the server for authentication is adding that access to * (or to dc=example,dc=com"), by * read. I tried using access to ou=Group and ou=Peoplle by * read, thinking that would allow the clients to authenticate, but that doesn't work either, The idea is to allow any machine configured as a client to use it for authentication, but also to restrict viewing the address book only to those with a proper bind dn name.
