It looks to me as if you are working with way too many unknowns to do any satisfactory trouble shooting. First, if you try to connect from your server to the services that you have set up, can you connect to the FTP server? If not, you need to fix your application configuration. If that...

I believe that you will need to look at ports 20 and 21 (ftp-data and ftp). Right now I believe that you are only capturing the control channel of the session, not the data flow. Try: tcpdump -i eth0 port (ftp or ftp-data) -n -tttt > /etc/outfile.txt & If you are ftping in PASV mode, you...

The port showing up as blocked does not necessarily mean that your port forwarding is not working. It could just as easily mean that your machine does not have its firewall rules updated, or your application is not yet listening on 5921. I would run netstat -na to ensure that your application...

No personal experience, but from what I read it is a Copper Clad Aluminum cable, which is fully capable of supporting Cat5e rates and distances (high frequency signals only travel on the skin of the wire, which is still copper). The possible downside that I have seen complaints about is that...

Can't say that I've ever seen a nibble flip in transmission or data storage. I've seen an MSB/LSB flip, which would yield a 0x4980 in your example. I've also seen a big endian/little endian reversal (for processors that have differing endianess, which would yield a 0x9201 in your example...

Have you tried the "Transparent Bridging" option? That should eliminate the second NAT at the PK5000. http://www.qwest.com/internethelp/modems/pk5000/modemDetail_pk5000_advanced.html pansophic

I couldn't find enough information on the Conexant D850 to determine if it is voice capable or not. I recall that NetWaiting was designed to suspend an active PPP connection while you took a voice call, then restore your PPP connection. Since it was designed to detect a call waiting while in a...

Assuming that your software runs on a Windows platform Dialogic may offer a solution. http://www.dialogic.com/products/tdm_boards/system_release_software/Diva_for_Windows_2000.htm?techspec=1&regID=5054 I'm assuming that you are doing POS or credit card / ATM authorization based on your...

Do you have a rule something like this: exten => _8.,n,Dial(SIP/+${EXTEN:1}@sipcarrier) in your dial plan? If I recall correctly, you would change it to: exten => _8.,n,Dial(SIP/+${EXTEN}@sipcarrier) essentially telling Asterisk not to drop the 8 on the outbound call leg. pansophic

Does a fax work on that line? Everything is pointing to a configuration issue with the line, not the modem. The configuration could be software or hardware as G0AOZ suggests. If a fax will work on the line, a modem should work as well. There are some obvious VoIP implementations were that is...

Obvious question first, can you remotely manage the Macs from on the LAN using the same software (preferably the same computer)? Is the firewall enabled on the Macs? If so, is the firewall configured to allow remote control? From an outside host (or the subnet associated with your VPN...

If I read your question correctly, you are dialing in from outside the PBX and you are not receiving modem answer tones? Can you tell if the modem has answered your call from the outside? If you stand next to the modem and call from your mobile, does the modem answer and try to handshake? If...

It is an Avocent Multiport Serial card. They were used quite a bit in the dial-up modem days and are still used in many Point-Of-Sale applications. www.connectivity.avocent.com/product-pdfs/0207-sstmp-tp.pdf But it could be one of their multi-modem cards as well, there wasn't much difference...

Sounds as if you have a virus or trojan on your machine and the bad guy is attempting to deploy some additional tools onto your system. The good news is that it is likely that there is only a minimally functional piece of malware on your system today, but it also sounds like they are attempting...

When ADSL first came out, the uplink speeds were very slow, typically no faster than your dialup modem (56Kbps). That technology has improved, but the tech people are probably just accustomed to telling employees that it won't work. You should try to convince the company that DSL is OK, but if...
