I've ben punding myhead on this issue. I've setup a new postifx server on rhel5. After editing the needed entries, i can't seem to send any outbound mails to yahoo or any other domains.My postconf -n is as follows:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
[code]...
I've been trying to ssh out of my home network to school computers and I keep getting:
ssh: connect to host sage.math.washington.edu port 22: Connection timed out
I've tried this on my machine (running Ubuntu 10.04) and on a windows 7 machine (using putty). I have been successful ssh'ing to this machine using either of the laptops from every other network I've tried, so I'm pretty sure it's something about my home network.
Is there a way I can count inbound/outbound mails for a particular user? I'm using sendmail as MTA and dovecot for POP3.
View 1 Replies View RelatedIn a little over my head here but eager to learn. Running Fedora 10 on an IBM T41. Trying to set up a local server so that I can run PHP and test webpages locally (I'm a client-side web designer). Went through the SendDerek tutorial and everything went great until I tried to check the port with canyouseeme.org. I get "Connection timed out" every time.
- The httpd service is started via the terminal.
- Port 80 is unblocked via "Firewall Configuration."
- I set up port forwarding on my router.
What am I missing? I just want to be able to have the local computer run my PHP scripts instead of having to upload them to a remote server every time I make a change.
when I am run:
ssh -v "login"@"server"
I get:
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to server ["address"] port 22.
debug1: connect to address "address" port 22: Connection timed out
ssh: connect to host "server" port 22: Connection timed out
I suppose this is because I am connecting from a public institute where there is a firewall that is blocking an outbound connection on port 22.Is there anyway I can bypass the firewall using the internet ?
How long normaly keep the mail server send mails on the outbox queue and try to send? What about hotmail, gmx and gmail mail server?
View 1 Replies View Relatedi have two PCs A and B, both are connected via LAN PC A Configuration is
IP Address 10.102.6.232
Broadcast Address 10.102.6.255
Subnet Mask 255.255.255.0
Default Route 10.102.6.2
Primary DNS 144.16.192.55

I am trying to connect B from A using command shh -X devendra@144.16.205.236, and facing error like ssh port 22 connection timed out.
I'm having an issue where a server in CA (1000/full) and in VA (100/full) have very lopsided data transfer.
CA -> VA with iperf shows ~20Mbps
VA -> CA with iperf shows ~93Mbps
If we change the CA server to 100/FULL, transfer speed is 93Mbps both ways.
Some tuning was done to TCP window scaling parameters, but it won't correct the issue, just improve the CA -> VA numbers to what is listed above. I will say, turning TCP window scaling OFF will lower the transfer speed both ways to < 20Mbps.
The only clue I have when looking at wireshark dumps is that the window scale going OUT would never go past 10240 (scale is 8, so 2^8 x 40bytes). In the opposite direction, the window size will go above 3MB (scaled).
It is not a bandwidth problem as iperf with UDP shows 93Mbps both ways. Local transfers (CA 1000/full to CA 100/full) show full speed both ways, so I feel it is strictly related to TCP window scaling.
RedHat 5 64-bit on both sides. Any ideas why it won't scale above 10240?
I have been playing with this for awhile now and I am ready to go postal.
I just want to move some files around and potentially rsync my net book with my desktop as well as learn the software (my primary reason)
Steps Taken.
Set Static IP address to machines on LAN
Turned on Port Forwarding (22)
Added Rule to UFW allow 22/TCP

Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf
I need to build a system that can provide me capacity to send more than 50.000 mails per hour.

View 8 Replies View RelatedI have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?

View 1 Replies View RelatedI've set up a fully functional e-mail server and can send and receive e-mails to and from an array of virtual domains without a problem. The only hiccup I have is that only root is able to send e-mails via mutt. I have not stipulated a sendmail line in the mutt configuration so it's sending e-mail with default configuration. How can I get it so that all users on the server can send outgoing e-mails via mutt?
Update: Solved this by following this http://inmyplace.info/2008/05/07/pos...ission-denied/
My sendmail doesn't accept connection from my own host.

I have 2 different networks :the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [url]..... on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7, CentOS 5.
I could say that the problem in DNS:because when I use this command in the private network machine: [url]...., it says connection timed out; no servers could be reached ,while in the public one, it works properly.....
