Example 1
ER75iX daemon.debug pppd[2363]: rcvd [LCP TermReq id=0x0 "Normal Termination by NCP"]
ER75iX daemon.info pppd[2363]: LCP terminated by peer (Normal Termination by NCP)
ER75iX daemon.debug pppd[2363]: sent [LCP TermAck id=0x0]
ER75iX daemon.info pppd[2363]: Hangup (SIGHUP)
ER75iX daemon.notice pppd[2363]: Modem hangup
ER75iX daemon.notice pppd[2363]: Connection terminated.
ER75iX daemon.info pppd[2363]: Terminating on signal 15
ER75iX daemon.info pppd[2363]: Exit.
The key line is highlighted in bold. The reason for such an error is incorrect access point (APN). Check the point name for errors. Another possible reason is the use of the access point designed to get the external IP address without connection of this service. The third reason is that number *99# is used instead of dial-up number *99***1#. Siemens modules operate properly only with the number *99***1#.

The reason for this error is that operator does not give DNS addresses, and Get DNS addresses from operator is ticked in the router settings. Remove this tick on the page Configuration > GPRS reconnect. Note: in this case, it becomes impossible to work with DNS addresses. Use the IP addresses or specify the DNS server on the computer. For example, 208.67.222.222 is Open DNS server address.
Yes, but it is not configurable. If the operating system hangs, then restart will be done automatically in 60 seconds. Forced daily reboot can be configured through the web interface in Configuration -> Daily reboot section. Also using user script you can configure reboot by SMS. Script example:
FROM="+71234567890"
CMD="zxcvbnm"
INT=60
while true; do
for i in `sms list`; do
sms read $i > /tmp/sms
sms delete $i
from=`cat /tmp/sms |head -n 2|tail -n 1`
msg=`cat /tmp/sms |head -n 4|tail -n 1`
if [ "$from" = "$FROM" ]; then
echo $msg|grep -q $CMD && reboot
fi
done
sleep $INT
done
Setting:
- Copy the text to the section "Administration -> Startup script" after the line "## This script will be executed at system startup".
- Change parameters:
- FROM - phone number from which it is allowed to receive command.
- CMD - code sequence. It is recommended to use random text to avoid false response.
- INT – interval in seconds in which new messages will be checked. It is not necessary to put less than 60.
- Tick the box "Run script at startup" and click "Save Script” button. Then you should either restart the router, or by connecting via telnet run the command "/mnt/settings/startup &" (without the quotes).
Note that the script deletes all the SMS after reading, regardless of whether they have command.
All devices of RUH (RUH, RUH2 and RC1) family support RS232 interface (3 wires RX, TX, COM; RC1 model additionally has power output 5.5 V on CTS line). Additionally, RUH, RUH2 and RC1 models optionally available on request with RS485 or RS422 interfaces with galvanic isolation or without it.
If you need to use interface RS485/422 on devices supporting RS232, you have to install the interfaces converter between the device to be connected and the router.
However, when using the converter (transforming the signal voltage level) together with the model RC1 additional power for the converter is not required because it is fed through "CTS" line of RS232 interface. You should use an active converter for all other models.
Yes. To do this you need to use the manual available for download from our website:
- How to restore the software for the router ER75iX Twin
- How to restore the router family RUH software
After the instructions download you should retrieve the device circuit board and do cable installation; cable installation is described in the downloaded document. Then connect the device via cable to your computer and follow the instructions.
No, but their support is planned and will be implemented in the next models. At the moment, for this purpose we recommend to use TC65 terminal solutions: GSM modem iRZ TC65i-485GI,GSM modem iRZ TC65 Lite, GSM modem iRZ TC65Smart (terminal).
You should make sure that if IPSec is disabled, the connection between the subnets nodes can be established (e.g. using ping). If not, make sure that the router and the remote device have set up routes to remote subnet through an external interface of the gateway.
If you use a third party device and the connection between nodes in a subnet is successfully installed, you should check ISAKMP and IPSEC encryption protocols.
Parameters for Cisco 870 series:
ISAKMP policy:
- encr 3des
- authentication pre-share
- group 2
- lifetime 3600
IPSEC (tunnel mode + proto ESP by default)
- crypto ipsec transform-set CRYPTO-SET esp-3des esp-sha-hmac
No, for these purposes we recommend using the wide range of iRZ modems.
It is possible to set different levels of detail logging in OpenVPN: you can use the configuration directive verb, it can take values from 0 to 11, where:
0 - disable all messages but critical;
1-4 - the optimal detail level;
5 - adds the ability to see network activity of the connection;
6-11 - full display; it is often used for debugging;
However, for parameter to take effect you need to switch to "read configuration from file" (Configuration -> OpenVPN Tunnel -> Take settings from => Configuration File) and add the configuration field with all necessary options and their values. More details about the use of this option you can find at official site of OpenVPN developer.
No, but it is planned; you can use Linux scripts support written in the shell (sh) language as an alternative. Also, in some cases, we are ready to make advances and consider the inclusion of Java VM in the specified router model. At the moment, for this purpose we recommend using TC65 terminal solutions: GSM modem iRZ TC65i-485GI,GSM modem iRZ TC65 Lite, GSM modem iRZ TC65Smart (terminal).
Answer 1: During connection using ser2net program - it is protocol, extended on the basis of RFC 2217 recommendations.
Answer 2: During connection according to the scheme COM <-> COM - own resources of serialoverip program are used.
Answer 1: Yes, the router firmware consists of software products distributed under GNU General Public License and Berkley Software Distribution License.
Answer 2: Note: If you want to use the software on the third-party manufacturer device, it is recommended to fully comply with the technological base and iRZ RUH router construction for firmware starting and functioning properly.
Yes. Currently this feature is present and is compatible with Link Fast Ethernet USB 2.0 Adapter, DUB E-100 model.
Startup script starts the last. Please note that the current edition of the system initialization program – init - does not support restart during signal sending, i.e. kill –HUP 1 command is useless.
At the moment there is AFTOGEN solution that is under active testing. If necessary, you can request to receive the program in order to test it in real conditions. Test report can be sent to support@radiofid.ru, or dafanasiev@radiofid.ru. Information about the test results will help us to promptly resolve problems and shorten the release terms of stable version.
Shure. We would be glad to represent you all information, improtant for developing process.
