Hello, I've got a FreeBSD 6 server running on my network that I used as a file server for my main computer. However I've really become frustrated with the slow up/down speeds I'm getting, about 100KB/s, which is about as bad as if I was using a "real" server. My setup is as follows:
Here are the results of tracert:
It seems to be since we're just going over the LAN, I should really be getting at least 500KB/s+ right? Is this a PowerLine issue, cable issue, FreeBSD issue, PC hardware isssue... etc? I'd be very thankful if I can get some ideas where to start to identify the bottleneck here, thanks a lot.
On one of of solaris 7 boxes whenever i telnet or ftp it takes sometime before i get the prompt...any quick ideas where I should look...Thanks (3 Replies)
One of our most frequent questions is how to automate ftp transfers. There are several approaches. Since I'm writing this post, we will start with my favorite technique. :)
In Automated FTP task I present a simple example of my ksh co-process technique. And note that later in this thread I... (0 Replies)
just as the title says.
thanks.

When I ssh to my box, an Ultra 5. I get prompted for password immediately. I enter it and have to wait sometimes a full minute for it to prompt for a password.
The same thing happens when i try to ftp to the box, it will say connected, but it takes forever to prompt for password, and... (2 Replies)

Hi again guys,
Earlier today, just all of a sudden, all SSH and FTP connections to my internal Linux box just slowed down to a crawl. After the connection/authentication though, everything was back to normal speed. Until you have to connect again. A box reboot didnt work either.
Now, from... (1 Reply)
How can one find the name and size of files ftp'ed during an old ftp transfer.
Is there any log where these details are stored or any UNIX command which can provide these details.
Thanks in advance. (4 Replies)
Hi All.
We are using AIX 5.3 ML9. There is 1 Gig NIC installed on two servers (Primary and Secondary) with Full Duplex Mode. We have scheduled a cronjob to copy the backup from primary to secondary thru FTP on WAN. The total data size is 15 GB and it took 9 Hours and 18 Mins with transfer rate... (6 Replies)
hi,
good morning.
Ma trying to ftp from one AIX machine to another on the same segment of the network. The ftp to eshtablish connection from machine A to machine B is quick, but the reverse is taking is much time (2 mins).

if_gre
GRE(4) BSD Kernel Interfaces Manual GRE(4)NAME
gre -- encapsulating network device
SYNOPSIS
To compile the driver into the kernel, place the following line in the kernel configuration file:
device gre
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_gre_load="YES"
DESCRIPTION
The gre network interface pseudo device encapsulates datagrams into IP. These encapsulated datagrams are routed to a destination host, where
they are decapsulated and further routed to their final destination. The ``tunnel'' appears to the inner datagrams as one hop.
gre interfaces are dynamically created and destroyed with the ifconfig(8) create and destroy subcommands.
This driver corresponds to RFC 2784. Encapsulated datagrams are prepended an outer datagram and a GRE header. The GRE header specifies the
type of the encapsulated datagram and thus allows for tunneling other protocols than IP. GRE mode is also the default tunnel mode on Cisco
routers. gre also supports Cisco WCCP protocol, both version 1 and version 2.
The gre interfaces support a number of additional parameters to the ifconfig(8):
grekey Set the GRE key used for outgoing packets. A value of 0 disables the key option.
enable_csum Enables checksum calculation for outgoing packets.
enable_seq Enables use of sequence number field in the GRE header for outgoing packets.
EXAMPLES
192.168.1.* --- Router A -------tunnel-------- Router B --- 192.168.2.*
/
/
+------ the Internet ------+
Assuming router A has the (external) IP address A and the internal address 192.168.1.1, while router B has external address B and internal
address 192.168.2.1, the following commands will configure the tunnel:
On router A:
ifconfig greN create
ifconfig greN inet 192.168.1.1 192.168.2.1
ifconfig greN inet tunnel A B
route add -net 192.168.2 -netmask 255.255.255.0 192.168.2.1
On router B:
ifconfig greN create
ifconfig greN inet 192.168.2.1 192.168.1.1
ifconfig greN inet tunnel B A
route add -net 192.168.1 -netmask 255.255.255.0 192.168.1.1
NOTES
The MTU of gre interfaces is set to 1476 by default, to match the value used by Cisco routers. This may not be an optimal value, depending
on the link between the two tunnel endpoints. It can be adjusted via ifconfig(8).
For correct operation, the gre device needs a route to the decapsulating host that does not run over the tunnel, as this would be a loop.
The kernel must be set to forward datagrams by setting the net.inet.ip.forwarding sysctl(8) variable to non-zero.
SEE ALSO gif(4), inet(4), ip(4), me(4), netintro(4), protocols(5), ifconfig(8), sysctl(8)
A description of GRE encapsulation can be found in RFC 2784 and RFC 2890.

BUGS
The current implementation uses the key only for outgoing packets. Incoming packets with a different key or without a key will be treated as
if they would belong to this interface.
The sequence number field also used only for outgoing packets.
