Remote login and Download Problem

[selva.k]

Hai All,

In our office we were using Aitel net connection with windows xp as gateway.Now we have changed our gateway machine to linux and bought a new beteel 220bxi modem/router and connected net using PPPoE mode and connected modem to linux machine by ethernet connection.Now we have following problems :

1)When we login into our remote servers using SSH,after a few minutes the connection breaks down with the following message :
Read from remote host "server name": Connection reset by peer
Connection to "server name" closed.

2)We can't uplaod files to our sites using FTP and can't send mails with attachment from windows machine.

3)When we download big file ( > 100mb) ,the download ends in half way.

pls help me to solve the problem....
Thanks,
Selva

Which was the modem you used for XP setup ? try with that.

If any problem in LINUX set up: No idea.
Please wait for other's comments.

which distro is the linux machine running? if possible post an ifconfig output from the linux machine

@essbebe
Ssh is a secure protocol run on machines and not routers.. mostly on linux machines..it does stuff like ftp etc but in a highly secure way..

Hai....
Thanks for replaying to my post.

I am using RHEL 5 and output of ifconfig :

[root@localhost ~]# ifconfig

@essbebe
Thanks for the information , didnt think that routers would have ssh support..

@selva.k
i presume when you said remote servers, you mean you wish to ssh to a remote machine.Your ifconfig looks good.. post output of sudo iptables -L .. incase something is blocking traffic

 

[selva.k]

I found that problem is not in gataway(linux) because i have connected modem directly to switch and i have encounterd the same problem . The problem is in modem.I have also got complients from my LAN clients that, yahoo messenger also disconnets frequently...

 

[superprash2003]

it could be that your modem gets disconnected often.. login to your modem , and under STATUS, post your SNR info . Another option would be to change your MTU values

@selva.k

Can you please confirm in menu options
in Beetel 450BX1"SSH"is listed anywhere ?
( Say access control Page)like FTP TELNET HTTP
for WAN LAN.

@superprash2003
Consider PF option.
