Autoselect ppp problems

Hi,
After upgrading old C2500 analog dial-in router with ext. modem pool and with IOS v.11.2.17 to new C3845 router with int. NM-8AM-V2 and IOS v. 12.4.10 i have folloing problems:
1. ppp session does not starts automatically with
'autoselect ppp' command in configuration
2. ppp session starts only when both 'autoselect ppp' and 'autoselect during-login' are configured, but remote users need access both EXEC-mode and PPP-mode w/o 'autoselect during-login' command and Username prompt.
Any ideas?
Router C2500 with old v.11.2.17 IOS configuration:
modemcap entry zyxel:FD=&f*m1s0=1s7=120s10=250:SPD=s20=3:DTE=19200

Removing "autoselect during-login" and adding "autoselect timeout 5". Doing this will allow AAA authentication not to be taken immediately after the connection is made.

Solaris 10 ppp problems

Hi!
I've big problems connecting to my isp using pppd included in Solaris 10 x86. I have Ericsson HiS modem, IDSL technology, connected to /dev/cua0 max speed set to 115200 kbps, it doesn't require chat script. I'd like to notice that there are no problems connecting my ISP on Linux with the same options used. I think the problem is a buggy PAP authentication negotiation with peer (diffs between linux and solaris in pppd debug log). Is there problem with configuration or (buggy?) old 2.4.0b1 version of ppp?? Any suggestions appreciated.

I need help especially from polish users, who experienced problems, or not, with HiS Ericsson iDSL modem (115,2 kbps) and Sun's ppp. Why can't I connect the same way as in for ex. FreeBSD or linux systems? Do I need a special configuration of serial port or modem? This is a fragment from typical pppd debug log:

PPP problems

Hello everyone !
I use pppd to establish a connection to the internet.
I open a /dev/ptmx and /dev/ptsX pair. I start pppd with STDIN and STDOUT set to the /dev/ptsX device.
The /dev/ptmx device is connected to a software that emulates an AT-command modem using a special USB modem.
The problem is:
* LCP, CHAP/PAP and IPCP packets work correctly.
* Incoming TCP/IP packets are sent to the kernel
(kdebug option of pppd shows that the TCP/IP packets arrive at the kernel)
* PPP does NOT send any outgoing TCP/IP packet
Q: Why does PPP not send any outgoing TCP/IP packets ?
I even tried the "notty" option of pppd.
Any ideas ?
Thanks.
Martin

I found out that the first PPP connection (over the network device sppp0) works.
Following connections over sppp0 work, too while connections over sppp1 etc. do NOT work.
I think this is a routing problem; the "default route" is bound to sppp0 and cannot be changed to sppp1.
I'm not 100% sure and I do not know how to handle this.
Another problem is that a non-blocking read() from /dev/ptmx sometimes returns 0 instead of errno=EWOULDBLOCK. Unfortunately I use read()==0 as hang-up detection.
Any ideas ?
Thanks.
Martin.

Multilink PPP problem

Hi Guys,
i got a situation here and hope someone will be able to help me out. Recently i configured a PPP multilink and am facing some issues after that.
Issue 1:
There seems to be lot of input error on multilink interface (150 errors in 40 mins)
Issue 2:
when any of the multilink member interface goes down (all other links are active), am getting packrt drops and request timed out when i ping my other end multi link interface atleast for some 30 sec , after which my response is ok.

Can't connect to Internet since 12/20/09???? PPP problem

I haven't been able to connect to internet here in Plymouth, MA since 12/19? Called numerous time to support and they say it is outage problems in area. My DSL light is steady on modem but when trying to connect the Internet light goes steady red! Anyone else having this problem in South East MA area? Does it normally take over a week to correct?

Outages almost never last a week. Verizon can't afford to leave customers without service for that long. I would suggest contacting Tech Support again. If the agent tells you that it's just an outage, ask to speak to their supervisor.

Strings panel autoselecting leading problems

I have a couple of dynamic text fields containing RETURN
(charCode 13).
They work fine when the Strings panel is set to "manual using
stage language", but when I switch to "automatically at runtime"
the leading seems to double. I use Flash 8 and flash player 8.
After searching all the Flash 8 litterature available on the
Adobe site, checking for autoinserted characters, and a number of
non-scientific trial-and-errors, I'm stuck.
The obvious work-around would be to publish each language
version separately, but all software demos I'm to produce would
benefit greatly from the auto-language feature.
Does anybody know what I'm doing wrong?
Wille

Yes, the format validation for it is number. I'm reasonably certain it always used to be number, though.
Should their be any detriment elsewhere if I had it changed to Char?
The field (in our test system) is protected against update - how can I remove the protection to test this?
Thanks for your help so far :)

RSA New Pin mode over PPP dialer

I have an RSA v6.1 server running SecurID and Steel Belted RADIUS. This is performing authentication requests, via RADIUS, to a Cisco router at an ISP which hosts a PPP dial in service over PSTN.
Currently I can dial successfully into the system using the standard windows ppp dialer over PSTN using my username and RSA pin+tokencode. However when the token is set to 'New Pin mode' or 'Next Token code' the connection fails to connect as it isn't prompting me for a new pin.
The RSA website says in order to support Next Token mode & New Pin Mode require the RADIUS client to
work in terminal mode before initiating ppp negotiation.
Does this problem ring any bells with anyone out there? What command to use on the cisco device to forward new pin mode requests to the dialer?

Andrew,
For new pin mode to work, you will need to enable interactive AKA exec logins. To do this you need to have following configuration.
interface Group-AsyncX
ip unnumbered Loopback0
encapsulation ppp
async mode interactive ! watch for framed and exec connections
peer default ip address pool dialin_pool
no keepalive
ppp authentication pap ! clear ok for one time pass
group-range 1/00 1/59
line x/x 1/x
login authentication default ! default command doesn't show in config
no flush-at-activation
modem InOut
autoselect during-login
autoselect ppp
autocommand ppp neg ! start ppp before giving exec prompt
To explain. SecureID users will enable a post terminal dial window in DialUp Networking config. When they connect, they will be prompted for user/token and pin if configured for that. If the Exec authentication an
authorization succeeds. The AS5350 will execute the ppp negotiate command,
which starts PPP for the session. The user may see garbage text in terminal depending on what version of DialUp Networking or client software they are using. They will need to click on the close/done/continue button.
The PC and AS5350 will then proceed with PPP.
However, we are going to by pass ppp authentication because we have already
authenticated for exec and we don't want the token to time out and cause a failure. PPP authorization should proceed as normal using the credentials provided for exec login.
Please use CHAP as PAP does not work for interactive authentication.
Regards,
~JG

Need ppp dailup to 2600 with NM-8AM

Router is 2600 with 12.3 IOS
I can't get my PPP sessions that are dialing in to use the defined radius server. Sessions connect, but don't authenticate. All this will be used for is emergency dialin.
What am I missing here?
doing a sho radius stats shows zero packets being exchanged between radius server and router.

fyi, if I have Winxp do a "pop-up" window after modem connects, I don't get ppp characters, but am prompted for username..
This makes no sense since I am forcing the connection to PPP in the Async group.

Slow ARP response for dial-in clients

I’ve been experiencing an intermittent issue with remote PC’s connecting to a Cisco AS5350 Universal Gateway - basically, a RAS server.
The issue as far as I’ve been able to pinpoint seems to be related to the amount of time it takes the dial-in client to register an ARP entry on the local network where the RAS server and other servers are connected.   If I start an extend ping to one of the servers on the local network (not to the RAS server) once my dial-up connection has been established, I typically see anywhere between 3 and 18 ICMP request timeouts before I start receiving replies. And if at the same time I start an extended ping to the IP address of the RAS server, ICMP replies are received immediately with no request timeouts.

The switch that the AS5350 and the servers are connected to is a WS-C2960G-8TC-L layer-2 switch with a very basic config. Basically they only thing I’ve changed during the course of my troubleshooting is the STP mode, STP forward time and to enabled STP portfast on the uplinks to the AS5350 and the server… see configuration below:

For troubleshooting, I enabled “debug arp” on the switch and attempted a dial-up connection to the AS5350. Once the call was established and I received a DHCP lease (192.168.240.131), I started an extended ping to a server (192.168.240.21) on the network… see below:

192.168.240.131 (0000.0000.0000) = PPP dial-in client on RAS server.

The first line of the debug shows the switch creating an “incomplete entry” for the dial-in client (192.168.240.131).
For all subsequent ICMP requests, you can see that the dial-in client has a MAC address of 0000.0000.0000 – I guess you would call this an incomplete entry.
On the last line of the debug output, you can see that the dial-in client (192.168.240.131) finally gets the MAC address of the AS5350 (000d.280c.fe1b) assigned to it – this is when we start getting ICMP replies.
So during this capture, there were 12 ICMP request timeouts before the dial-in client started receiving replies.

Cisco AS5350 IOS: c5350-ik9s-mz.123-11.T11.bin
Is anyone aware of an IOS bug or an error in my configurations that could be causing the delay in creating an ARP entry for the dial-in client?
I am open to any suggestions.
BTW, if I add static arp entries on the server, ICMP replies are typically received after one or two request timeouts.
However, I feel this is not a solution to the problem, only a band-aid fix.

Hi Krishnamraj,
How many records are you gettnig from server..?? Are they very huge..??

Configure ras dial up internet

I have an AS5300
Cisco Internetwork Operating System Software
IOS (tm) 5300 Software (C5300-I-M), Version 12.2(16), RELEASE SOFTWARE (fc3)
This is a machine that I inherited which allows users to dial a number which comes in to the Cisco via a PRI and gives them an IP address, allowing them internet access.
the problem I am having is that users can dial via their PC modem and they get an IP address assigned to them from the Cisco. But they have no internet connectivity at all. They are not even able to ping the Cisco.
I am pretty new to Cisco in general, so any kind of information would be useful, including debug methods and commands. Pointer to sample configurations would help out a lot as well. Below is my config

Ok, i managed to get it to work. When setting up the pptp adapter on my windows xp I checked the box 'Negotiate multi-link for single link connections'.
However I still don't understand how this makes the connection work. I am not using multi link.
Could this be anything to do with the fact that I am not doing any form of authentication and authorization? It is a open RAS where any one can connect so long as they dial the right number.

How to configure Null Modem on serial port?

Previously, I use a windows XP to accept incoming connection by Network Connections > Create a New Connection > Accept Incoming Connection
I would like to deploy an Cisco router to replace this XP, how can i configure it? I convert the RS232 to smart serial cable, here is my configuration, fa0/0 connected to office LAN and S0/0 connected to null modem devices
The connection is up, however, the S0/0 is flapping up and down, and return packet is dropped by the router with msg encryption error

Thank you Ravens Fan
I used your idea on the receive part and it worked fine but it has two problems:
1) when I use the waveform graph it keeps increasing the X scale infinitely.
2) when using the waveform chart and set the chart history to 100 it work fine at first but it goes out of shape after a while.
I think that's all due to the n dimention array is there a way to make a 100 dimention array in a way that new elements erase old ones.
Another thing I
wanted to be sure I understand it right, on the sending loop I should set the “digital
waveform to binary” to U16 so that at the receiving part the chart (or graph)
will read it as U32 ,but shouldn’t the receiving signal be different than the
sent signal; since different points.
I attached the new VI.
Thank you

Cisco 2811 PVDM 32

Hi guys
I am currently trying to configure a 2811 with a PVDM2-36DM and a HWIC-1CE1T1-PRI to allow remote users to dial in using both ISDN and pstn modem access. Is this possible using this combination of WICS?

this is the config we are running. we can dial a Windows XP machine in using PSTN no problem, however ISDN will authenticate the link, and then can't negotiate a PPP link
this is the config we are applying

Reverse SSH not working for Cisco 3750.Plz help.

Hi,
I have configured the reverse ssh mentioned on the cisco document:http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gt_rssh.html#wp1051457.
But now I am running into the issue that When I issue command ssh -l alex:rotary1 192.38.6.8 from the cli of the router I’m presented with a password prompt.
I enter my password and get connected. However at this point when I type, for example, the atdt command I don’t see any output displayed.
So I tried typing command atdt <tel no.> and at the same time ran a debug modem on a separate session. It was from the separate session I could see the call been made to the remote device and connected successfully. However almost immediately the modem debug displays message 0236596: Dec 7 2010 12:18:18.236 GMT: TTY69: cleanup pending. Delaying DTR. At no point do I see output displayed on the session where I connected to the modem.
When using telnet to connect, i.e using the same modem and the same remote device, we have had no problems it is just with SSH.
Any suggestion on this will be highly appriciated.
Thanks
Alex.

Philip,
I first thank you for coming forward to help me on this.
I use the 30DM(Digital Modem) Card on the router. I have configured on of this modem on the PRI card(1/18) to make outbound calls. We use this dailup to cyclades the devices located on our remote office. Hence we loose the main internet connectivity we use this option as a backup.

Please let me know is this a bug or anything else. AS the same setup works fine when I use TElnet rather than ssh.
Thanks in advance.
