Hello,
I have just installed ubuntu 16.04 into my pc.
Locally everything works fine, it takes data from internet, I am also able to connect to apache in the same local network. When I try to reach from mobile network, I can't establish ssh, apache site is not displaying in my browser etc.
Ifconfig:
interfaces:
I also set static ip as DMZ host in router. To be sure I rebooted both pc and router but nothing changes.
Hi,
How do I get my working directory always shown in the unix editor? i.e if I am now at /Home/abc/xyz/, I want to see this absolute path displayed ( and now only display when I type pwd).
thanks for the kind help.

I am trying to obtain the file name (not including sub file name), however, I still cannot have the string output. :(
2 existed files at /tmp, AAA.new and BBB.last
Originally, the output result is needed to be shown as follows,

Hi,
On solaris 10, t5120,
I don't understand what are the last 2 file systems
so last 2 file systems what are they, why are they getting shown and also confused why the swap is shown so many times and different size when I set it to 16 G at the time of installing solaris 10. ( rest... (3 Replies)
Hello,
This is a 2 node sun cluster 3.2 on solaris 10(x86)
I am using an unique ~512M disk (c0d1) on each node and slice 6 on this disk for globaldevices. While everything looks like fine, the 'Fail' is bothering me.

Hi All,
I am having knowledge on some basics of ssh and wanted to know what are the public keys and how can we create and implement it in connecting server.
Please provide the information for the above, it would be helpful for me.

Hi
I am using the dd command on solaris 10 and the output doesn't include the MB/s statistic that you get in Linux,
is this not available or am I missing a switch of some sort

I'm currently running a CUPS server and it shows the printers on other computers just fine, but after a while they disappear. I found out, that restarting /etc/init.d/cups-browsed fixes the problem (for about 15min).
When the printers disappear, the cups-browsed service is still running, so I... (0 Replies)

netmasks
netmasks(4) File Formats netmasks(4)NAME
netmasks - network mask database
SYNOPSIS
/etc/inet/netmasks
/etc/netmasks
DESCRIPTION
The netmasks file contains network masks used to implement IP subnetting. It supports both standard subnetting as specified in RFC-950 and
variable length subnetting as specified in RFC-1519. When using standard subnetting there should be a single line for each network that is
subnetted in this file with the network number, any number of SPACE or TAB characters, and the network mask to use on that network. Network
numbers and masks may be specified in the conventional IP `.' (dot) notation (like IP host addresses, but with zeroes for the host part).
For example,
128.32.0.0 255.255.255.0
can be used to specify that the Class B network 128.32.0.0 should have eight bits of subnet field and eight bits of host field, in addition
to the standard sixteen bits in the network field.
When using variable length subnetting, the format is identical. However, there should be a line for each subnet with the first field being
the subnet and the second field being the netmask that applies to that subnet. The users of the database, such as ifconfig(1M), perform a
lookup to find the longest possible matching mask. It is possible to combine the RFC-950 and RFC-1519 form of subnet masks in the net-
masks file. For example,
128.32.0.0 255.255.255.0
128.32.27.0 255.255.255.240
128.32.27.16 255.255.255.240
128.32.27.32 255.255.255.240
128.32.27.48 255.255.255.240
128.32.27.64 255.255.255.240
128.32.27.80 255.255.255.240
128.32.27.96 255.255.255.240
128.32.27.112 255.255.255.240
128.32.27.128 255.255.255.240
128.32.27.144 255.255.255.240
128.32.27.160 255.255.255.240
128.32.27.176 255.255.255.240
128.32.27.192 255.255.255.240
128.32.27.208 255.255.255.240
128.32.27.224 255.255.255.240
128.32.27.240 255.255.255.240
128.32.64.0 255.255.255.192
can be used to specify different netmasks in different parts of the 128.32.0.0 Class B network number. Addresses 128.32.27.0 through
128.32.27.255 have a subnet mask with 28 bits in the combined network and subnet fields (often referred to as the subnet field) and 4 bits
in the host field. Furthermore, addresses 128.32.64.0 through 128.32.64.63 have a 26 bits in the subnet field. Finally, all other
addresses in the range 128.32.0.0 through 128.32.255.255 have a 24 bit subnet field.
Invalid entries are ignored.
