[Aaron Ooi]

Hi all,

Today i facing some issue on my unix box 11.23 with putty version 0.60. I unable to use putty to telnet, ssh and ssh2 to the server. However i able to telnet using window command prompt to telnet to the server.

i have use all kind of putty version but still cannot ssh to the server, somehow after 2 hour i able to use putty to ssh to the server. In syslog i saw some abnormal message:-

Did anyone of you having the same issue before. I have check with the network guy, there is no network interruption at that time.

I know nothing, but that looks to me more
like a problem with sshd on the server than
any problem with the SSH client.

That talks to telnetd, not to sshd.

How old is your sshd? "sshd -xxx"?

[Aaron Ooi]

ok first of all, i need to let you know telnet using putty is not able also, only able to telnet using command prompt.

i have try to refresh the sshd and telnetd daemon but it still no luck. But somehow after about 40 minute i restart both daemon i able to connect using putty again either ssh or telnet with putty.

if you can try also "RESET" -> LAN

reset the lan interfaces...
lanadmin ----> lan ----> reset lan interfaces..

Hi Guy today the problem happen again, i notice everytime i login using ssh with putty this error recorded in syslog

fatal: mm_memvalid: end < address: 0 < -140000

Do anyone know what does this mean, i have search around no info found. I have even rebooted the server, restart inetd, sshd and telnetd as well . But it still no luck

HI,
Un-installt the putty and install it again or used putty.exe if you dont want to install the same.

Is this secret information? (Why?)

[mvpel]

Aaron - PuTTY version 0.60 (latest) has telnet, rlogin, serial port, and raw modes in addition to SSH. Look for the radio buttons under the hostname box in the Session tab.

[Aaron Ooi]

Hi Johnson,

I have reset the LAN interface, it still the same. Btw i dbelieve is not the LAN interface problem as i still able to telnet in.

Hi Surai,
I have uninstall and reinstall the new version of putty it still no luck, other than that i have use other such as secure crt but it still not helping.

Hi Steven,
I not sure what you mean by how old is your sshd. btw this is the version:-

OpenSSH_4.4p1-hpn12v11, OpenSSL 0.9.7l 28 Sep 2006
HP-UX Secure Shell-A.04.40.011, HP-UX Secure Shell version

For the daemon i have restarted it as well.

Hi mvpel,
Yup i know we can connect using other option in putty, but the problem is i have some schedule job need to use ssh to connect. Btw connect using telnet in putty is no issue.

You might consider trying a newer version:
