IOS XR - ipv4 virtual address

In case when there is failover between RP on the GSR; tend to lose the ssh /
telnet session for few mintues.
is this ipv4 virtual address needs to be configured. how does it help? i have configured it but still loses my connection.
ipv4 virtual address 10.10.138.19 255.255.255.248
MgmtEth0/8/CPU0/0 unassigned Up Up
MgmtEth0/9/CPU0/0 10.10..138.20 Up Up
Thanks.

Hello Atif,
in order to have a working virtual address both management interfaces need to have an IP address in the same IP subnet
see from one of our CRS:
sh ip int br | inc Mgmt
MgmtEth0/RP1/CPU0/0 10.85.17.50 Up Up
MgmtEth0/RP0/CPU0/0 10.85.17.49 Up Up
then you configure the virtual IP address in the same IP subnet
sh run | inc 10.85.17.
Building configuration...
ipv4 virtual address 10.85.17.51 255.255.255.240
10 permit ipv4 10.85.17.48 0.0.0.15 any
ipv4 address 10.85.17.49 255.255.255.240
ipv4 address 10.85.17.50 255.255.255.240
Hope to help
Giuseppe

Java programs are run by a virtual machine which is running in userland. They don't "mess" with the kernel.
OTOH, each userland program interacts with the kernel through system calls, signals, pageing activity, ...
My guess is that it's either broken hardware, or a fault in the linux kernel.
Is the crash reproducible? Does ist always crash with the same error message, at the same "eip" location?
If the crashes are sporadic and non deterministic, with different error messages each time, then I'd say it's
a hardware problem. Otherwise, it could be a linux kernel software problem.

Can we assign IPv4 IP address pool to IPv6 VPN Client

We are planning to enable IPv6 SSL VPN clients, Let me explain the current setup
We have Cisco ASA firewall used for SSL VPN and Cisco ACS for user authentication and RSA for two factor authentication.
LAN Server are in IPv4 only..
Requirement :
Client (IPv6) --- Cloud (IPv6) ---- Outsite(IPv6) -Cisco ASA - Inside(IPv4) ----- ACS (IPv4) & RSA (IPv4)
Client with IPv6 internet connectivity connect to SSL VPN with IPv6, Cisco ASA outside interface with IPv6 address will receive the request.
Qus:
1. Will Cisco ASA check two factor authentication with ACS and RSA both are in IPv4 address for an IPv6 client ?
2. Once if authenticated, Cisco ASA can assign IPv4/IPv6 address pool to the client, if i prefer only IPv4 address pool and client will get IPv4 address as tunnel interface IP address. Will it work? Means IPv4 over IPv6 SSL VPN tunnel.
Thanks
Sankar

AFAIR, with SSL we support IPv4 and IPv6 assigned IP addresses, with IPsec IKEv2 we only support IPv4 addressing.
Query to AAA servers are separate process, from user<-> headend authentication flow, unless we're talking about IKEv2 with standard EAP methods.

Ipv4 mapped addresses bind problem: address already in use.

Hello. It's me again with another, may be newbie, question.
This time I observe different behavior binding different type of ip addresses on tcp sockets. For instance
- when I bind ipv4 mapped addresses, if there is a remaining old socket in TIME_WAIT state from a previous run
I get the error 'Address already in use', event with SO_REUSEADDR set.
- when I bind another type of ipv6 or just ipv4 addresses. if there if a remaining old socket in TIME_WAIT state from
a previous run, the bind is successful (SO_REUSEADDR is set).
How can be explained this behavior?
Thanks a lot.
Details
=======
I made a small program to test this. This program:
- dump the addresses to be used in bind() and connect()
- creates a LISTEN SOCKET calling
- socket(AF_INET6, SOCK_STREAM, 0)
- fcntl(F_SETFD, fcntl(F_GETFD) | FD_CLOEXEC)
- fcntl(F_SETFL, fcntl(F_GETFL) | O_NONBLOCK),
- setsockopt(SO_REUSEADDR),
- setsockopt(SO_KEEPALIVE),
- setsockopt(TCP_NODELAY),
- bind()
- listen()
- creates a CONNECTING SOCKET calling
- socket(AF_INET6, SOCK_STREAM, 0)
- fcntl(F_SETFD, fcntl(F_GETFD) | FD_CLOEXEC)
- fcntl(F_SETFL, fcntl(F_GETFL) | O_NONBLOCK),
- setsockopt(SO_REUSEADDR),
- setsockopt(SO_KEEPALIVE),
- setsockopt(TCP_NODELAY),
- connect()
- creates a ACCEPTED SOCKET calling
- accept()
- fcntl(F_SETFD, fcntl(F_GETFD) | FD_CLOEXEC)
- fcntl(F_SETFL, fcntl(F_GETFL) | O_NONBLOCK),
- setsockopt(SO_REUSEADDR),
- setsockopt(SO_KEEPALIVE),
- setsockopt(TCP_NODELAY),
- issue a std::system( "netstat -an | grep 10329" )
- wait with select() for a write event in the CONNECTING SOCKET
- wait with select() for a write event in the ACCEPTED SOCKET
- close the accepted socket
- close the connecting socket
- close the listen socket
- issue another std::system( "netstat -an | grep 10329" )
- exit(0)
Note: please don't get confused with my notation of addresses, the last component, after the last colon, is the port.
I run it with ipv4 mapped listen address, with this result:
$ ./test_reuseaddr listen_address=0.0.0.0:10329 connect_address=127.0.0.1:10329

Sorry, to use such short forms in forums as i dont know much about this. i rarly use java forum. well, i removed the code that i gave u for server starting. but still it is giving me the same error. this time i put it in a java bean file.(Hint "u" is just another short form).
Did you try the suggestion to put a log statement just before you start the server? Or put a breakpoint at that line and see how often it is reached.
Because the only reason for this problem is that something is already listening at that port.
And if there's really nothing listening before you start you application, then only your application itself can listen there already, so the logical conclusion for me would be that you're starting the Server twice.

Hide my Ip address Show virtual address

Dear Friends,
I am developing an JSP application and using Tomcat 4.1, for running my application i have to type my ip address and port number
http://<<ip address>>:<<port no>>/ <<Root folder name>>.
I need to type any virtual address http://programs_java instead of http://127.1.1.0:8080/programs_java
Thanks in advance
Rengaraj.R

You cannot do anything by installing some software. If you are inside a network then there will be some DNS servers where the mapping of ipaddress and names are stored. So you have to get your ip mapped to a name which you want to type in address bar, in the DNS server. Ask your network administrator for more details on how to get it mapped.

How can I check the virtual-address up using show command in ACE?

I want to check the virtual-address using show command.
however, there are not in ACE. So I used the ping to check virtual-address status in ACE
I want to know the command what is verify virtual-address status , using show command
Thank :)

Try -> show arp
There you have a Type column and a Status column.
Look for the entry "VSERVER" in the Type column

Virtual address location in process WSDL

Hi,
now we use following approach:
We refer to default WSDL at http://<server>:<port>/orabpel/<domain>/<process name>/<process name>?wsdl
Where address location is the default revision of the process: http://<server>:<port>/orabpel/<domain>/<process name>/<revision>
Is there any possibility to refer to WSDL with 'virtual address location' that always refers to default revision?
We want that our partner has one WSDL with address location
and we can transparently change process revisions without notifying our partner to clear wsdl caches and refresh address location?
Are there any possibilities?
(we use BPEL 10.1.2.0.0 )
Thank You and Reagrds
Karel

Hi,
To always use the latest revision of a process you need to exclude the <revision> part of the Location url. To dynamically set the url's at runtime you can use the following in a assign activity:
<copy>
<from expression="string(bpws:getVariableData('urlVariable','/ns1:ParameterCollection/ns1:location'))"/>
<to partnerLink="RunUcmJasperReport" bpelx:property="location"/>
</copy>
<copy>
<from expression="string(bpws:getVariableData('urlVariable','/ns1:ParameterCollection/ns1:wsdlLocation'))"/>
<to partnerLink="RunUcmJasperReport" bpelx:property="wsdlRuntimeLocation"/>
</copy>
Make sure you assign both wsdlLocation and Location and that the <from> part explicitly is a string. This works in 10.1.3 but i do not know if it also was available in 10.1.2
Kind Regards,
Andre

Physical Address to Virtual address

Hi all,
Are there any DDI/DKI API's to convert physical address to virtual address and vice versa. If there are no API's available is there any other way/method to achive this.
Regards and Thanx in advance
Pradeep

in general, you're not supposed to need to do that, although hat_getpkfnum will work. If you are trying to use dma, it is better to use the dma functions such as ddi_dma_alloc_handle with ddi_dma_mem_alloc and ddi_dma_addr_bind_handle, or dvma_kaddr_load.

How does OpenSPARC translate Virtual Address to Physical Address or Vice V

The i386 page address system has three levels: dir, page, offset. The 32 bits virtual address consists of dir, page, offset. When the process releases a virtual address to read a memory content, the MMU of i386 will translate the virtual address to physical address as follows:1,Based on the value of CR3 register and dir of virtual address, MMU returns the base address of page.2, Based on the the base address of page and value of page of virtual address, MMU returns the base address of physical page.3, Based on the base address of physical page and value of offset of virtual address, MMU returns physical memory address. 4, Read the content of physical memory address.
However, when I read the source code of the bw_r_tlb of OpenSPARC�s MMU, I am puzzled. I am not clear how is the page address system of OpenSPARC implement.
Will you offer me some hints about it ? And are there any documents about it?
Thanks a lot!

It would be good to add the definition of Hypervisor in the wikipedia.
Thanks

find the Hypervisor API (such as sun4v_intr_setstate, sun4v_intr_gettarget) has been
integrated with Linux kernel. In other words, it is implemented in Linux kernel. All the time, I think
Hypervisor API is an independent layer which provides an easy way to switch among all kinds of OS. But now,
I find it is a part of Linux. If so, what a role does Hypervisor API take? Why do we name it Hypervisor API
rather than a part of Linux? It do puzzle me, am I wrong?
The Hypervisor API ("application programming interface") is fully described in the UltraSPARC T1 Hypervisor API Specification, which is downloadable from page http://opensparc-t1.sunsource.net/index.html .
As a brief digression ... the term "Hypervisor API" has always seemed a bit oxymoronic to me -- given the historic equivalency of "application" to "nonprivileged". After all, isn't it more of an "SPI" (supervisor programming interface) because it services privileged supervisor (operating system) software, not nonprivileged (application) software? But if you think of a guest OS as an "application" (in the general sense of the word) supported by the Hypervisor, then "Hypervisor API" makes some sense.
Now, regarding Hypervisor API and Linux. If you read the UltraSPARC T1 Hypervisor API Specification, you'll find that Hypervisor API calls are defined (appropriately enough) in terms of native SPARC assembly language. I haven't looked at the Linux source code, but I'd bet a considerable sum of money that the Linux sun4v_intr_gettarget() function is a C-language wrapper around a SPARC assemly-language routine that sets up arguments, performs a trap to the Hypervisor intr_gettarget function, and returns the result(s) to the caller.
In any case, all actual Hypervisor code is fully implemented in the Hypervisor, not in Linux or Solaris or FreeBSD or Wind River Linux or any other OS running on top of the Hypervisor. Each OS may implement some "wrapper" code around Hypervisor calls, but no actual Hypervisor functionality actually resides in a guest OS. In fact, it can't reside in a guest OS because it must run in hyperprivileged mode and guest operating systems run in "merely" Privileged mode.

Virtual address to physical address

Hi,
How do i convert kernel virtual address to physical address.... do we have
any DDI function for this.?.. i am writing a driver for a pci card... my
card needs the physical address of the memory location so that it can dump
data to this location..
OS: SOlaris 7 on intel pc..
gurus any idea how to do this stuff???....
TIA
azad

The recommended way to do this is by using the ddi_dma* functions. I would suggest reading the entire "Writing Device Drivers", but pay particular attention to the chapters on DMA and the section in the chapter on character drivers that deals with DMA.

Nope. After turning it off, FF became NOT RESPONDING. Restarted, and happened again. Using Safe Mode now.

IPv4 Multicast address range

Hello there.
How can we classify the IPv4 multicast range ( 224.0.0.0 - 239.255.255.255 ) in terms of Public or Private addresses ?
regards.

It's a mixture of private and public addresses depending on the particular subnet within that range. See below

Virtual address configure listener.ora and tnsnames.ora files on Solaris10

Hi,
I have installed Oracle 10g R2 on Solaris 10 U4 SPARC.
I need to configure Oracle 10g to work with Storage Foundation for Oracle v5.0.
After Oracle installation listener.ora listens on host IP address.
So I have changed to listens on the Virtual IP address. This is a requirement:
All listeners to be configured must listen to the same virtual IP address
Could you please tell what to correct to have my Oracle working correctly?
listener.ora:
-bash-3.00$ cat listener.ora
# listener.ora Network Configuration File: /export/home/u01/app/oracle/product/10.2.0/Db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /export/home/u01/app/oracle/product/10.2.0/Db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.160.19.64)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
tnsnames.ora:
-bash-3.00$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /export/home/u01/app/oracle/product/10.2.0/Db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.160.19.64)(PORT = 1158))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
Also connecting by web browser http://10.160.19.64:1158/em I am not able to start listener:
Details TNS-12541: TNS:no listener
Using the command listener start it starts successfully.
Kind regards,
Daniel

The port in listener.ora nad tnsnames.ora are now the same - 1521
After this trying logining by Web page there is an error:
Error
Io exception: The Network Adapter could not establish the connection
When I run netca tool and I reconfigure listener netca change the IP address to sun3 which has 10.160.19.49. After this listener works fine and I am able to connect by Web page.
bge0 10.160.19.49 - is the base IP address
bge0:2 10.160.19.64 - is the virtual IP address
I want listener to listen on 10.160.19.64.

IPv4 private addressing tradeoff: small footprint vs even VLSM length?

Is minimising one's use of the private address space to avoid unnecesary potential overlap worth the hassle of having un-even VLSM lengths?
I am designing my first non-trivial IPv4 addressing scheme in the 10.0.0.0/8 range. Just two small branch offices, but on the access-layer, I'm putting servers, printers, desktops and phones onto separate VLANs. (In fact, when doing L3 at the access-layer, you can quickly end up with multiple VLANs).
Now, few of these VLANs are so big that they'll need a /24 all to themselves. In fact, a /27 for phones and printers will be fine. I'll give a /24 to desktops because 255.255.255.0 is the only mask which semi-technical users understand. Maybe a /25 for servers, which gives a bit of room for further subnetting and putting VMs onto their own VLANs.
I'll summarise each site over DMVPN as a /21 subnet. Neat.
But at each site the routing tables look messy, with the router sporting addresses like 10.9.13.129/27 and there isn't any real pattern between the L3 address and the VLAN number.
Why don't I just dole out /24's to each VLAN, After all, I'm hardly going to minimise conflict with private IP addresses chosen by prospective partners by using /20's instead of /21's for each site (right?), and even if they do, NAT can handle all these situations elegantly (right?).
What about you, would you minimise your footprint in the address space and deal with 'unevenness' in subnet sizes? Or would you be easier on your eyes now and simply bite the bullet if you had to NAT one day?
thanks!
David.

I chose Alessio's as the 'correct' answer, since it mentioned route summarisation. But both answers were correct in the sense that they were quite reasonable.
In the end, I decided to go wtih my varying-length VLSM approach, to keep the address-sprawl at each site confined to a /21 subnet. I don't find the varying-length VLSM to be much of an nuisance in practice. I miss out on being able to make the 3rd octet 'line up' with the VLAN, but I feel that's a pretty delicate affair anyhow. Some person just has to give VLAN100 as a 'best practice' for the Voice VLAN, for example, and you either start working with a /17 at each site (minimally), or abandon your numbering scheme. You'd really have to go with a /16 for each site to ensure you can number 254 VLANs in this fashion. And that means for each site that you chose, there's a 1-in-256 chance you'll pick the same second octet as someone else. With my scheme, there is a 1 in 8192 chance that I'll pick the same address range, so I've decreased the likelyhood of a conflict by a factor of 32.
At the end of the day though, so long as route summarisation works, all other considerations seem to be a matter of taste.
